Introduction: Surgery is often delayed in patients with proximal femoral fractures who receive oral anticoagulants, to avoid complications related to perioperative bleeding. However, surgery delay may increase the risk of postoperative mortality. Our primary goal was to understand whether anticoagulated patients benefit from early surgery in terms of survival and perioperative complications., Methods: This is a multicenter retrospective cohort study of 581,189 patients with proximal femoral fractures. About 2.0 % (n = 11,385) received direct oral anticoagulants (DOAC) and 1.5 % (n = 8,726) received warfarin. Surgery was performed within 48 h in 37.6 % of DOAC patients, 27.6 % of warfarin patients and in 41.9 % of nonanticoagulated patients. Survival analysis was applied to compare mortality rate, blood transfusions, systemic complications and surgical complications during hospitalization between the study groups., Results: Patients receiving anticoagulation were older and had more comorbidities than patients without anticoagulation. There were overall similar rates of mortality (0.8 %, 1.1 % and 1.2 %) and surgical complications (2.1 %, 2.1 % and 2.2 %) in non-anticoagulated, DOAC and warfarin patients. Blood transfusions and systemic complications were higher in all anticoagulated patients regardless of surgery timing. There were comparable rates of early surgery (41.9 %, 37.6 % and 27.6 %, respectively). When operated early, DOAC patients had more surgical complications (OR=1.24, p = 0.04). Warfarin patients operated early had higher mortality (OR=1.48, p = 0.08) and higher risk of blood transfusions (OR=1.24, p < 0.001)., Discussion: Age and comorbidities could explain higher rates of postoperative systemic complications in anticoagulated patients. Nevertheless, overall short-term mortality was similar between the groups. Early surgery was associated with higher rates of surgical complications in DOAC patients. When operated early, patients receiving warfarin were at an increased risk of mortality (p = 0.08) and perioperative blood transfusions., Competing Interests: Declaration of competing interest All authors have no conflict of interest., (Copyright © 2024 Elsevier Ltd.

Background: Hip fractures carry a substantial risk of complications and death. This study aimed to report the 90-day incidence of mortality, major perioperative complications and in-hospital timelines after a hip fracture in the Spanish HIP ATTACK-1 trial cohort, comparing with the non-Spanish cohort., Methods: Prospective cohort study of Spanish patients nested in the HIP ATTACK-1 trial. The HIP ATTACK-1 was an international, randomized, controlled trial (17 countries, 69 hospitals, 7 in Spain, highest recruiting country). Patients were randomized to either accelerated surgery (goal of surgery within 6 h of diagnosis) or standard care. Participants were ≥45 years of age who presented with a low-energy hip fracture requiring surgery., Results: Among 534 patients in the Spanish cohort, 69 (12.9 %) patients died at 90 days follow-up, compared to 225 (9.2 %) in the non-Spanish cohort (p = 0.009), mostly due to higher nonvascular related mortality. A composite of major postoperative complication occurred in 126 patients (23.6 %). The most common perioperative complications were myocardial injury (189 patients, 35.4 %), infection with no sepsis (86 patients, 16.1 %) and perioperative delirium (84 patients, 15.7 %); all these complication rates in Spain were significantly higher than the non-Spanish patients (29.2 % p = 0.005; 11.9 % p = 0.008 and 9.2 % p < 0.0001, respectively). Spanish cohort patients were older and had more comorbidities than the non-Spanish cohort, evidencing their greater frailty at baseline. Among Spanish patients, the median time from hip fracture diagnosis to surgery was 30.0 h (IQR 21.1-53.9) in the standard-care group, with 68.8 % of patients receiving surgery within 48 h of diagnosis. This median time was lower in the non-Spanish cohort (22.8 h, IQR 9.5-37.0), where 82.1 % of patients were operated within 48 h., Conclusions: In the HIP ATTACK-1 trial, 1 in 8 patients died 90 days after a hip fracture in Spain. The most common complication after a hip fracture was myocardial injury, followed by infection and delirium. Spanish patients had worse outcomes than non-Spanish patients. Research needs to focus on new interventions such as accelerated surgery and perioperative troponin measurement with the appropriate investment of resources, to prevent and identify early these complications with a goal of improving mortality for this high-risk population., Level of Evidence: II., Competing Interests: Declaration of competing interest Dr. Ernesto Guerra-Farfán and Dr. PJ Devereaux received research grants from Smith & Nephew for this investigator-initiated trial.

Background: Proximal femoral fractures are severe injuries in geriatric patients. Additionally, geriatric patients are at a high risk of death due to coronavirus disease 2019 (COVID-19)., Objective: To identify predictors of mortality in geriatric patients with COVID-19 and concurrent proximal femoral fractures., Material and Methods: Patients who underwent surgical treatment for proximal femoral fractures and also tested positive for COVID-19 were included. The age, gender, the American Society of Anesthesiology (ASA) score and the admission from a nursing home were considered as variables. The rate of reoperations, the mortality at 3 months and discharge home were evaluated as outcomes., Results: In this study 46 patients with COVID-19 (female/male 31/15, median age 87.0 years with an interquartile range [IQR] of 9.8 years) met the inclusion criteria. Of these, 32 patients (69.6%) had to be cared for in the intensive care unit and 26 patients (56.5%) had a severe course of COVID-19 with pneumonia. The median length of hospital stay for survivors was 19 (IQR 17.5) days and 4 of the patients (8.7%) required surgical revision. The in-hospital and 3‑month mortality were 40.0% (n = 17) and 43.5% (n = 20), respectively. The factors which influenced the in-hospital and 3‑month mortality rates were admission from a nursing home, the presence of pneumonia (increased the risk of death) and female gender (protective)., Conclusion: The occurrence of COVID-19 in patients with proximal femoral fractures has a high mortality. Admission from a nursing home and the presence of pneumonia increased the risk of death, whereas women were at lower risk., (© 2024.

We studied factors affecting osteoporotic hip fracture mortality in Hawai'i, a region with unique geography and racial composition. Men, older adults, higher ASA score, lower BMI, and NHPI race were associated with higher mortality. This is the first study demonstrating increased mortality risk after hip fracture in NHPI patients., Purpose: To estimate mortality rates and identify specific risk factors associated with 1-year mortality after osteoporotic hip fracture in Hawai'i., Methods: A retrospective review of adults (≥ 50 years) hospitalized with an osteoporotic hip fracture at a large multicenter healthcare system in Hawai'i from 2011 to 2019. The Kaplan-Meier curves and log-rank tests examined survival probability by sex, age group, race/ethnicity, primary insurance, body mass index (BMI), and American Society of Anesthesiologists (ASA) physical status classification. After accounting for potential confounders, adjusted hazard ratios (aHR) and 95% confidence intervals (CI) were obtained from Cox proportional hazards regression models., Results: We identified 1755 cases of osteoporotic hip fracture. The cumulative mortality rate 1 year after fracture was 14.4%. Older age (aHR 3.50; 95% CI 2.13-5.76 for ≥ 90 vs 50-69), higher ASA score (aHR 5.21; 95% CI 3.09-8.77 for ASA 4-5 vs 1-2), and Native Hawaiian/Pacific Islander (NHPI) race (aHR 1.84; 95% CI 1.10-3.07 vs. White) were independently associated with higher mortality risk. Female sex (aHR 0.64; 95% CI 0.49-0.84 vs male sex) and higher BMI (aHR 0.35; 95% CI 0.18-0.68 for obese vs underweight) were associated with lower mortality risk., Conclusion: In our study, men, older adults, higher ASA score, lower BMI, and NHPI race were associated with significantly higher mortality risk after osteoporotic hip fracture. NHPIs are an especially vulnerable group and comprise a significant portion of Hawai'i's population. Further research is needed to address the causes of higher mortality and interventions to reduce hip fractures and associated mortality., (© 2024.

Objective: To determine country/region-specific mortality (in-hospital, 30-day and 1-year) following hip fracture across the Asia Pacific region., Methods: Five databases MEDLINE, PUBMED, EMBASE, Web of Science and the Cochrane Library were searched to identify studies that reported mortality following hospitalisation for low-trauma hip fracture in adults aged ≥50 years with data from 2010 to 30 September 2021. There were no restrictions on study design or language. Pooled mortality estimates for countries/regions with ≥2 studies were calculated using random-effects models., Results: In total 244 studies were included in the meta-analysis. 123 studies (1,382,810 patients, 13 countries/regions) reported in-hospital mortality which ranged from 1.4 % in Japan [95 %CI 1.2-1.7], Singapore [95 %CI 1.0-1.6], China [95 %CI 0.8-2.3] and Hong Kong SAR [95 %CI 0.8-2.6] to 5.5 % [95 %CI 4.1-7.2] in New Zealand. 92 studies (628,450 patients, 13 countries/regions) reported 30-day mortality which ranged from 1.2 % in Japan [95 %CI 0.9-1.5] and Thailand [95 %CI 0.7-2.0] to 7.4 % [95 %CI 7.0-7.8] in Australia. 142 studies (1,139,752 patients, 14 countries/regions) reported 1-year mortality which ranged from 10.8 % [95 %CI 9.6-12.1] in Singapore to 23.3 % [95 %CI 22.3-24.5] in Australia and 23.8 % in New Zealand., Conclusion: There is substantial variation in mortality across the Asia Pacific region. Short-term mortality rates in Asian countries, notably Japan and Singapore, are up to four-fold lower than for Australia and New Zealand. This difference, although less marked, is sustained at 1-year with a two-fold lower mortality rate in Asia. This meta-analysis is the first to delineate these differences, further studies are required to understand the reasons for this variation., Competing Interests: Declaration of competing interest Lara Harvey, Narelle Payne, Azriel Tan, Jing Zhang, Yong Chang Lai, Morag Taylor, Elizabeth Armstrong, Catherine McVeigh, Anna Stefanie Mikolaizak, Rismah Hairu, Taylor Scott, Madeleine Bishop, and Jacqueline Close declare that they have no conflict of interest., (Copyright © 2024.

The article was designed to explore the clinical efficacy of 'Fast-track Management' guided by ERAS concept under the multidisciplinary collaboration model for early operation of femoral intertrochanteric fracture in the elderly. The clinical data of 198 intertrochanteric fracture in the elderly were retrospectively analyzed. According to the diagnosis and treatment mode, they were divided into cooperative group and routine group. The preoperative waiting time, preoperative deep venous thrombosis, operation time, intraoperative bleeding, hospitalization time, Harris score, VAS score, intervention effect of eras concept, complication occurrence, and 1-year mortality were made a comparison. There were notable differences in the preoperative waiting time, the number of cases of preoperative deep vein thrombosis and the length of hospital stay between the cooperative group and routine group. The incidence of complications in the cooperative group was 9.38%, which was significantly lower than that in the conventional group, 54.90%. The 1-year mortality rate was clearly lower in the cooperative group than in the routine group. At 1 and 2 weeks after operation, VAS, HAMA and PSQI of the cooperative group were lower, but Harris and Barthel were higher than the routine group. At 1 month after operation, there was no clear difference in VAS and Harris between the cooperative group and routine group. The establishment of 'Fast-track Management' based on ERAS concept in the multidisciplinary collaboration model can effectively alleviate the pain of femoral intertrochanteric fracture in the elderly, shorten the hospital stay, reduce the occurrence of postoperative complications and the mortality within 1 year.

Objective: To investigate the risk factors influencing 1-year mortality after intramedullary nail fixation for fragile intertrochanteric fracture in elderly individuals., Methods: The medical records of 622 consecutive elderly patients (aged ≥ 65 years) with fragile intertrochanteric fractures treated with proximal femoral nail anti-rotation (PFNA) and followed-up were retrospectively analyzed. The patients were divided into death and survival groups according to their survival status within 1 year after surgery, and the differences in age, sex, region of residence, tobacco use, alcohol use, body mass index (BMI), comorbidities (hypertension, diabetes mellitus, coronary heart disease, stroke, dementia, chronic obstructive pulmonary disease, pneumonia), preoperative hemoglobin, preoperative albumin, deep vein thrombosis, fracture type (AO classification), injury-to-surgery time, American Society of Anesthesiologists (ASA) score, anesthesia modality, duration of surgery, intraoperative blood loss, and blood transfusion were compared. The Kaplan-Meier method was used for univariate analysis to screen for statistically significant differences between the two groups, and the data were entered into the Cox proportional hazards model for multivariate analysis to determine independent risk factors affecting 1-year postoperative mortality. For subgroup analysis, we explored the varying effects of hypoproteinemia and being underweight in patients of different genders, as well as the effects of different age ranges, different injury-to-surgery times, and different blood transfusion volumes on 1-year postoperative mortality., Results: The mortality rates at 1, 3, and 6 months, and 1 year after surgery were 3.9%, 7.2%, 10.1%, and 15.3%, respectively. Univariate analysis showed that advanced age, male sex, tobacco use, underweight (BMI < 18.5), coronary heart disease, stroke, dementia, pneumonia, number of comorbidities ≥ 3, hypoproteinemia and injury-to-surgery time ≤ 2 days were associated with the 1-year postoperative survival status (P < 0.1). Multivariate analysis revealed that advanced age, male sex, dementia, number of comorbidities ≥ 3, hypoalbuminemia, and being underweight were independent risk factors for 1-year postoperative mortality. Subgroup analysis showed that being underweight was associated with 1-year postoperative mortality only in male patients but not in female patients, whereas hypoproteinemia was associated with 1-year postoperative mortality in both male and female patients. Furthermore, an injury-to-surgery time of less than 2 days improved patient survival, and patients more than 80 years old showed an elevated risk of postoperative mortality., Conclusions: Preoperative health status is a critical predictor of postoperative outcomes in elderly patients with fragile intertrochanteric fractures. Priority care should be given to the patients who are elderly, male, have dementia, have comorbidities, or are malnourished. Prompt nutritional reinforcement should be provided to patients with intertrochanteric fractures with comorbid hypoproteinemia and underweight. Furthermore, surgery should be performed as early as possible in patients with fewer comorbidities., (© 2024. The Author(s).)

Background: The aims of this study were to assess whether delayed admission from the ED influenced mortality risk, length of acute hospital stay, risk of developing delirium and return to domicile for patients presenting with a hip fracture., Methods: A single centre service evaluation was undertaken including patients aged over 50 years who were admitted to a Scottish hospital through the ED with a hip fracture during a 42-month period (from January 2019 to June 2022). Delay was defined as spending >4 hours in the ED from arrival. Patient demographics and perioperative variables and mortality were collected. Cox regression analysis (adjusting for age, sex, season, socioeconomic status, American Society of Anesthesiologists grade, place of residence, fracture type, delirium and time from ward to theatre) was used to determine the independent association between delayed disposition from the ED and mortality (90 days and final follow-up) as recorded on a regional database., Results: The cohort consisted of 3266 patients with a mean age of 81 years, of which 2359 (72.2%) were female. 1261 (38.6%) patients stayed >4 hours in ED. The median follow-up was 529 days, during which time there were 1314 (40.2%) deaths. Survival at 90 days was significantly lower (hazard ratio [HR] 0.76, 95% CI 0.63 to 0.91) for patients who stayed >4 hours (92.9%) compared with those who stayed ≤4 hours (95.7%). Delayed disposition was independently associated with an increased mortality risk at 90 days (adjusted HR 1.36, 95% CI 1.12 to 1.63, p=0.001) and at final follow-up (adjusted HR 1.15, 95% CI 1.03 to 1.29, p=0.017). Delay was also associated with a longer length of hospital stay (difference in medians of 1 day, p<0.001). There were no differences in the risk of delirium on the ward (p=0.256) or return to place of residence (p≥0.315)., Conclusion: Delayed disposition from our ED was associated with an increased mortality risk and longer length of hospital stay in patients presenting with a hip fracture., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Purpose: The primary goal of this randomised controlled trial was to investigate whether there are differences in the outcome between the Gamma3 nail and a sliding hip screw (SHS) regarding quality of life 1 year after surgery., Methods: In a controlled randomised trial, we compared the Gamma3 nail (Stryker) and a SHS (Omega, Stryker) in the treatment of 193 patients with pertrochanteric fractures. The follow-up period was 12 months. The outcomes included the surgical duration, health-related quality of life measured with the EQ-5D Index and a Visual Analogue Scale (VAS), the living situation and use of walking aid before trauma and 52 weeks after surgery; the Parker Mobility Score; the Harris Hip Score; and the revision, complication and mortality rates., Results: The Gamma3 group had a significantly shorter surgical duration than the SHS group (p < 0.0001). Implant-related complications were significantly lower in the Gamma3 group (p > 0.05). The revision rate was significantly lower in the Gamma3 group based on intention-to-treat (p = 0.0336) as well as as-treated (p = 0.0302) analyses. Otherwise, we did not find significant difference between the two groups regarding the EQ-5D Index and VAS scores, the Parker Mobility Score, the Harris Hip Score, the mortality rate, the use of walking aids and the living situation., Conclusion: There were no detectable differences between the groups in terms of quality of life and clinical scores 12 months after surgery. The surgical duration and revision rate were superior for the Gamma3 group., (© 2024. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.)

Objective: To explore the relationship between anion gap (AG) and length of stay (LOS) in patients undergoing hip fracture surgery., Methods: Clinical data of patients diagnosed with hip fracture and undergoing surgery were extracted from the Medical Information Mart for Intensive Care IV (MIMIC-IV) database. Logistic regression analysis by adjusting different covariables and threshold effect analysis were used to analyze the relationship between AG and LOS. Subgroup analysis and interaction test were also performed to detect their relationship. Receiver Operating Characteristic (ROC) analysis was performed to identify the prediction performance and cutoff value of AG.Kaplan-Meier (KM) survival analysis was used to explore the influence of AG on overall survival., Results: A total of 1508 patients were enrolled and the median LOS was 4.9 days. The correlation between AG and LOS > 7 days was observed among 3 regression models when regarding AG as continuous variables (all OR > 1, all P < 0.05). After stratifying samples with AG quartiles, their relationship was only presented in the Q4 group both in model 1 and model 2 (all P < 0.001). The risk of LOS > 7 days gradually increased with increasing AG quartiles (all P for trend < 0.05). Further, threshold effect analysis found that their association was mainly observed when AG ≥ 14 mEq/L (OR = 1.122, P < 0.001). Subgroup analysis showed that their correlation was not influenced by sex, age, BMI, ethnicity, classification of fracture, therapeutic method, CHD, hypertension, osteoporosis, diabetes and admitted to the ICU (all P for interaction > 0.05). ROC analysis identified 14.5 as the cutoff value of AG for predicted LOS > 7 days. Survival analysis found that patients in the AG < 14.5 group had better overall survival., Conclusion: In patients undergoing hip fracture surgery, the AG was positively correlated with LOS, and 14.5 mEq/L AG was the cutoff value for predicting LOS > 7 days. The cutoff value can favorably distinguish the survival difference of patients., (© 2024. The Author(s).)

Context: Current clinical guidelines recommend a drug holiday after extended use of oral bisphosphonates. However, no studies have investigated the effect of drug holidays before hip fractures on postfracture mortality., Objective: This work aimed to investigate the effect of a drug holiday on postfracture mortality in patients with extended use of oral bisphosphonates., Methods: This retrospective, population-based cohort study took place among all patients with hip fractures in Victoria, Australia, from 2014 to 2018. Patients were adherent to oral alendronate or risedronate for 5 years or more prior to hip fracture. Group-based trajectory modeling categorized patients into different bisphosphonate usage after 5-year good adherence. The main outcome measure was postfracture mortality., Results: We identified 365 patients with good adherence (medication possession ratio ≥80%) to oral alendronate/risedronate for 5 years or more. Most patients (69%) continued to use oral bisphosphonates until admission for hip fracture; 17% had discontinued for 1 year and 14% had discontinued for 2 years. Postfracture mortality was higher in patients who had discontinued risedronate for 1 year (hazard ratio [HR] 2.37; 95% CI, 1.24-4.53) and 2 years (HR 3.08; 95% CI, 1.48-6.41) prior to hip fracture. No increase or decrease in postfracture mortality was observed in patients who had discontinued alendronate for 1 year (HR 0.59; 95% CI, 0.29-1.18) or 2 years (HR 1.05; 95% CI, 0.57-1.93) prior to hip fracture., Conclusion: Postfracture mortality is higher in people who discontinue risedronate, but not alendronate, for 1 or 2 years after being adherent to treatment for at least 5 years. The type of bisphosphonate may be a factor to consider when planning drug holidays., (© The Author(s) 2024. Published by Oxford University Press on behalf of the Endocrine Society.)

Aims: To determine if patient ethnicity among patients with a hip fracture influences the type of fracture, surgical care, and outcome., Methods: This was an observational cohort study using a linked dataset combining data from the National Hip Fracture Database and Hospital Episode Statistics in England and Wales. Patients' odds of dying at one year were modelled using logistic regression with adjustment for ethnicity and clinically relevant covariates., Results: A total of 563,640 patients were included between 1 April 2011 and 1 October 2020. Of these, 476,469 (85%) had a coded ethnicity for analysis. Non-white patients tended to be younger (mean 81.2 vs 83.0 years), and were more commonly male (34.9% vs 28.5%; p < 0.001). They were less likely to be admitted from institutional care (12.9% vs 21.8%; p < 0.001), to have normal cognition (53.3% vs 62.0%; p < 0.001), and to be free of comorbidities (22.0% vs 26.8%; p < 0.001), but were more likely to be from the most deprived areas (29.4% vs 17.3%; p < 0.001). Non-white patients were more likely to experience delay to surgery for medical reasons (14.8% vs 12.7%; p < 0.001), more likely to be treated with an intramedullary nail or a sliding hip screw (52.5% vs 45.1%; p < 0.001), and less likely to be mobilized by the day after surgery (74.3% vs 79.0%; p < 0.001). Mortality was higher among non-white inpatients (9.2% vs 8.4% for white), but was lower at one year after hip fracture (26.6% vs 30.3%)., Conclusion: Our study identified serious problems with the quality of NHS ethnicity data. Despite this, we have shown that there is complex variation in case-mix and hip fracture morphology between ethnic groups. We have also identified variations in care received between ethnic groups, and that disparities in healthcare may contribute to poorer outcome. Inpatient mortality is higher in non-white patients, although this finding reverses after discharge, and one-year mortality is lower. Patients from ethnic minority backgrounds experience disparities in healthcare, however at one year postoperatively non-white patients have a statistically significant lower mortality after controlling for relevant clinical covariates., Competing Interests: S.

Purpose: To analyse the time-to-surgery of a centre of excellence in hip fractures of the elderly and its influence on inpatient mortality and postoperative complications., Methods: A cross-sectional cohort study was conducted. The sample universe consisted of 4,364 patients admitted to a university clinic in Chía, Colombia during the year 2018 to 2023 with ICD-10 diagnoses corresponding to femur fractures. After eliminating duplicates and application of inclusion and exclusion criteria, the final sample included was 269 patients. Qualitative and quantitative variables were analysed, such as: sex, age, age group, type of fracture, type of surgical procedure, time-to-surgery, time to discharge, inpatient mortality and postoperative complications., Results: The mean time-to-surgery from admission was 70.16 h or 2.92 days (IQR 37-87). Patients were divided into three subgroups of time in which they were taken to surgery: <24 h (11.89%), 24-48 h (33.82%) and > 48 h (54.27%). The overall mortality rate was 1.85% for a total of five deceased patients, two of whom belonged to the 24-48-hour group and three to the > 48 h group. Higher rates of postoperative complications were observed in the > 48-hours group (n: 39, 14.49%), followed by the 24-48-hour group (n: 25, 9.29%) and the < 24-hour group (n: 7, 2.6%)., Conclusions: Patients operated for a hip fracture in > 48 h since admission had a slightly higher rate of postoperative complications. No significant difference was observed regarding inpatient mortality when compared to the 24-48-hour group., (© 2024. The Author(s) under exclusive licence to SICOT aisbl.)

Background: The aim of this study was to analyse the association between use of cement for stem fixation in hip hemiarthroplasty and the outcomes of mobility, mortality, and discharge destination., Methods: The Irish Hip Fracture Database was examined from 2016 to 2020 to assess for any difference in post op mobility, 7-day, 14-day and inpatient mortality, and discharge destination., Results: A total of 7109 hemi-arthroplasties were identified from 2016 to 2020. 71.6 % were cemented (n = 5,172), with 28.4 % uncemented (1,937). There was no difference in day 1 post op mobilisation (79.7 % vs 80.9 %) or cumulative ambulatory score on discharge (2.5 vs 2.4). The mortality rate was equivocal at all time points between the cemented and uncemented groups (7 day (.9 % vs 1.2 %), 14 day (1.9 % vs 2.3 %), inpatient (4 % vs 5.1 %)). There was no difference in length of stay (11 vs 12 days) or discharge to home directly (21 % vs 27 %)., Conclusion: The use of cement did not have any significant difference on post op mortality, mobility or discharge destination., (Copyright © 2023.

Fragility fractures of the hip are one of the most important triggers of poor health outcomes in older adults. They often result in limitations in the ability of patients to care for themselves and mortality remains high. Orthogeriatric co-management may improve outcomes for this high-risk population. However, the impact on long-term results has not yet been definitively clarified. The purpose of this study was to present the influence of orthogeriatric co-management on mortality and self-care ability, as measured by the Barthel score, one year after hip fracture in people ≥ 60 years.A systematic literature search was performed in accordance with the process steps of identification, selection, and evaluation, with a systematic search of the MEDLINE, CINAHL Complete and Cochrane Library databases in the period from February to March 2022. Articles in English and German published between 2012 and 2022 were included. Twelve studies were finally used.Six studies demonstrated a statistically significant reduction in the one-year mortality rate. Only one of four studies evaluating self-care ability showed a significant improvement when the patient was treated on a specialised ward.Orthogeriatric co-management seems to be beneficial in positively influencing one-year mortality and self-care ability. In view of the heterogeneous results, the implementation of this care model can only be recommended to a limited extent., Competing Interests: Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (Thieme.

A validation of the GeRi-Score on 120-day mortality, the impact of a pre-operative visit by a geriatrician, and timing of surgery on the outcome was conducted. The score has predictive value for 120-day mortality. No advantage was found for surgery within 24 h or a preoperative geriatric visit., Purpose: Numerous tools predict mortality among patients with hip fractures, but they include many variables, require time-consuming assessment, and are difficult to calculate. The GeRi-Score provides a quick method of pre-operative assessment. The aim of this study is to validate the score in the 120-day follow-up and determine the impact of a pre-operative visit by a geriatrician and timing of surgery on the patient outcome., Methods: A retrospective analysis of the AltersTraumaRegister DGU ® from 2017 to 2021 was conducted, including all proximal femur fractures. The patients were divided into low-, moderate-, and high-risk groups based on the GeRi-Score. Mortality was analyzed using logistic regression. To determine the influence of the time to surgery and the preoperative visit by a geriatrician, matching was performed using the exact GeRi-Score, preoperative walking ability, type of fracture, and the time to surgery., Results: The study included 38,570 patients, divided into 12,673 low-risk, 18,338 moderate-risk, and 7,559 high-risk patients. The moderate-risk group had three times the mortality risk of the low-risk group (OR 3.19 (95% CI 2.68-3.79; p<0.001)), while the high-risk group had almost eight times the mortality risk than the low-risk group (OR 7.82 (95% CI 6.51-9.93; p<0.001)). No advantage was found for surgery within the first 24 h across all groups. There was a correlation of a preoperative geriatric visit and mortality showing an increase in the moderate and high-risk group on in-house mortality., Conclusions: The GeRi-Score has predictive value for 120-day mortality. No advantage was found for surgery within 24 h. The analysis did not demonstrate a benefit of the preoperative geriatric visit, but more data are needed., (© 2024.

Background and Purpose:  Fracture-related infections (FRIs) after osteosynthesis for hip fractures have not been thoroughly investigated. Our primary aim was to assess the association between FRIs and mortality after osteosynthesis for hip fracture. Secondary aims were to investigate the incidence, microbiology, and general epidemiological aspects of these FRIs., Methods:  This retrospective single-center study included 1,455 patients > 18 years old with non-pathological hip fractures treated with osteosynthesis between 2015 and 2019. Medical records were reviewed and FRIs were diagnosed based on current consensus criteria. The follow-up period was 2 years. Mortality was estimated using Kaplan-Meier survival analysis. Cox regression analyses were performed to investigate the potential association between FRIs, as a time-dependent variable, and increased mortality., Results: The median age for the entire cohort was 83 (interquartile range 75-89) years and 69% were females. At the 2-year follow-up mark, the crude mortality rate was 33% in the non-FRI group and 69% (11 of 16 patients) in the FRI group. Cox regression analysis assessing mortality risk revealed a hazard ratio of 3.5 (95% confidence interval [CI] 1.9-6.4) when adjusted for confounders. The incidence of FRI was 1.1% (16 of 1,455 patients). Staphylococcus aureus was the most common pathogen. Most FRI patients (94%) required at least 1 revision and 56% underwent ≥ 2 revision., Conclusion:  We found an association between FRIs after hip fracture osteosynthesis and increased mortality, underscoring the critical need for FRI prevention measures in this frail patient group. The incidence and microbiological findings were consistent with previous studies.

Background: There are no clear recommendations for optimal transfusion thresholds for patients with coronary artery disease who undergo noncardiac surgery. By comparing restrictive and liberal transfusion strategies for coronary artery disease combined with hip surgery, this study hopes to provide recommendations for transfusion strategies in this special population., Methods: A total of 805 patients from the FOCUS trial (Transfusion Trigger Trial for Functional Outcomes in Cardiovascular Patients Undergoing Surgical Hip Fracture Repair) with coronary artery disease combined with hip surgery were divided into two groups based on transfusion thresholds: restricted transfusion (a hemoglobin level of 8 g/deciliter) and liberal transfusion (a hemoglobin threshold of 10 g/deciliter). The primary outcome of this study was a composite endpoint including in-hospital death, myocardial infarction, unstable angina, and acute heart failure. The secondary endpoints included other in-hospital adverse events and 30- and 60-day follow-up events. Analyses were performed by intention to treat., Results: Except for the proportion of congestive heart failure patients, the baseline levels of the two groups were comparable. The median number of transfusion units in the liberal transfusion group was 2 units, and the median transfusion volume in the restricted transfusion group was 0 units. The primary outcome was not significantly different between the two groups (9.2% vs. 9.4%, p = 0.91). The incidence of in-hospital myocardial infarction events was lower in the liberal transfusion group than in the restricted transfusion group (3.2% vs. 6.2%) (OR = 0.51, P = 0.048). The remaining in-hospital endpoint events, except for myocardial infarction, were not significantly different between the two groups. The 30-day and 60-day endpoints of death and inability to walk independently were not significantly different between the two groups, with ORs (95% CI) of 1.00 (0.75-1.31) and 1.06 (0.80-1.41), respectively. We also found no interaction between transfusion strategies and factors such as age, sex, or multiple underlying comorbidities at the 60-day follow-up., Conclusions: There was no significant difference in the in-hospital, 30-day or 60-day outcome endpoints between the two groups. However, this study demonstrated that a liberal transfusion strategy tends to reduce the incidence of in-hospital myocardial infarction events in patients with coronary artery disease combined with hip surgery compared to a restrictive transfusion strategy. More high-quality studies should be designed to investigate the optimal transfusion threshold in patients with coronary artery disease treated without cardiac surgery., (© 2024. The Author(s).)

The outcome of this study was to identify 9-year survivors of intertrochanteric fracture at each stage of chronic kidney disease (CKD) and to investigate the risk factors associated with mortality following surgery with proximal femoral nail anti-rotation (PFNA). 443 elderly intertrochanteric fractures underwent PFNA fixation were recruited. Mortality rate was identified until 9 years. We compared the survival time of hip fracture in each stage of CKD. A regression analysis was used to determine the association between risk factors and one-year mortality. The overall median survival time was 7.1 years. The Kaplan-Meier curve was significantly different in each CKD stage especially in CKD5. In addition, the incidence rate of mortality was highest in CKD 5 (17.4%) and the median survival time in CKD 5 was 3.3 years. The multivariate analysis demonstrated that heart disease, operative time > 60 min, presence of pulmonary embolism, and poor to fair Harris hip score were significantly increased mortality. CKD stage 5 is associated with the highest mortality rate and the shortest median time of survival during the 9-year follow up. Patients who have high risk should focus on long-term care planning, including the counseling for their healthcare providers and families., (© 2024. The Author(s).)

The first Fragility Hip Fracture Registry has been established in Greece. The in-hospital length of stay was 10.8 days and was significantly influenced by the delayed surgical fixation. The increased age, the higher ASA grade, and the male gender influenced negatively the 30-day mortality, which reached 7.5%., Background: The increased incidence of fragility hip fractures constitutes a great challenge to the health care professionals and causes a significant burden on national health care systems around the globe. Fragility hip fracture registries have been used in many countries in order to document the cotemporary situation in each country and to identify potential weaknesses of the local health care systems., Aim: The aim of the herein study is to present the results of the pilot implementation of the first fragility hip fracture registry in Greece, which was developed by the Greek Chapter of Fragility Fracture Network (FFN Gr), and use the neural networks in the analysis of the results., Materials and Methods: Seven orthopaedic departments from six different hospitals in Greece participated in the present pilot study. All fragility hip fractures from September 2022 until December 2023 were prospectively collected and documented using a central database. For this purpose, the 22 points of minimum common data set, proposed by the Global Fragility Fracture Network, with the addition of the 30-day mortality was used., Results: A total of 1009 patients who sustained a fragility hip fracture were included in the study. The mean age of the cohort was 82.2 ± 8.6 years with the majority of patients being female (72%). Sixty percent (60%) of the patients had an extracapsular hip fracture, with a mean ASA grade 2.6 ± 0.8. Intramedullary nailing and hip hemiarthroplasty were the surgical treatments of choice in the majority of extra- and intra-capsular hip fractures respectively. The mean hospital length of stay of the patients was 10.8 ± 8.5 days, and the 30-day mortality was 7.5%. The multivariant analysis revealed that the age, the ASA grade and the male gender had a significant contribution to the 30-day mortality. The neural network model had a significant under-the-curve predictive value (0.778), with age being the most important predictive factor. The length of stay was significantly influenced only by the delayed surgical fixation (more than 36 h from admission)., Conclusions: The present pilot study provides evidence that establishing a fragility hip fracture registry in Greece is feasible and demonstrates that the minimum common data set can be used as the base of any new registry. In Greece, patients with a fragility hip fracture stay in the hospital for approximately 11 days and have 7.5% 30-day mortality. Unfortunately, due to the logistics of the public healthcare system, they do not receive surgical fixation in a timely manner, which is a factor that negatively affects their length of in-hospital stay., (© 2024.

The population has aged; there is a greater risk of osteoporosis and hip fracture. We describe the standards of care for hip fractures in various hospitals of Mexico. A total of 1042 subjects participated. The acute mortality was 4.3%., Significance: Hip fracture registries provide a means to compare care and establish improvement processes., Background: The Mexican population has aged; thus, there is a greater risk of osteoporosis, and its main consequence is hip fracture due to fragility. Its incidence is high, and it is expected to increase due to aging in our country. International guidelines provide standardized recommendations for the care of people with hip fractures, while hip fracture registries provide a means to compare care with local, national, and international clinical standards and establish improvement processes., Objective: Describe the standards of care for hip fractures in various hospital centers of the Mexican Social Security Institute., Methods: This was an observational, multicenter, longitudinal, and descriptive study. It included 24 hospital centers in Mexico. Informed consent was obtained. Data were recorded during the hospital stay, epidemiological data, and management, and follow-up was carried out 30 and 120 days after discharge. The information was analyzed using SPSS version 22.0., Results: A total of 1042 subjects aged 79.5 ± 7.6 years participated, mostly women (n = 739; 70.9%) from the community (n = 1,021; 98.0%) and with functional independence (Barthel 80.9 ± 22.2). The transfer time to the emergency room was 4.6 ± 14.6 days. Pertrochanteric hip fracture was the most common (n = 570, 54.7%). The most common type of procedure was dynamic hip screw (DHS) (n = 399; 40.1%). Documented thromboprophylaxis was granted in 91.5% (n = 953) and antibiotic prophylaxis in 53.0% (n = 552) of the patients. The goal of 36 h for the surgical procedure was achieved in 7.6% of the subjects (n = 76), with the most frequent cause being a delay in scheduling (n = 673, 67.6%). The mean time from emergency room to surgery was 7.8 ± 7.0 days. The acute mortality rate was 4.3%. Secondary pharmacologic prevention upon discharge occurred in 64.2% of patients. At 30 days, 370 subjects (37.1%) were lost to follow-up, with a mortality of 3%, while at 120 days, 166 subjects (27.8%) were lost, with a mortality of 2.8%., Conclusion: In the hospital centers where the study was carried out, there are still no standards of care for hip fractures, which makes it necessary to rethink the care for this population group through a strategy focused on meeting those standards., (© 2024.

Background: Hip fractures in older people result in increased mortality., Objective: We developed and validated an accurate and simple prognostic scoring system for hip fractures that can be used preoperatively., Design: Retrospective study., Setting: Multicenter., Participants: Patients aged ≥65 years with hip fractures who underwent surgery between 2011 and 2021 were enrolled., Methods: The significant factors were determined with logistic regression analysis, and a scoring system was developed. The patients were classified into three groups, and a log-rank test was performed to evaluate 1-year survival rates. The model was internally and externally validated using the 5-fold cross-validation and data from another hospital, respectively., Results: We included 1026 patients. The analysis revealed eight significant prognostic factors: sex, body mass index, history of chronic heart failure and malignancy, activities of daily living (ADLs) before injury, hemoglobin and the prognostic nutritional index (PNI) at injury, and the American Society of Anesthesiologists Physical Status. The area under the receiver operating characteristic curve (AUC) after internal validation was 0.853. The external validation data consisted of 110 patients. The AUC of the model for the validation data was 0.905, showing outstanding discrimination. Sensitivity and specificity were 88.7% vs. 100% and 93.3% vs. 95.2% for the development and validation data, respectively., Conclusions: We developed and validated an accurate and simple prognostic scoring system for hip fractures using only preoperative factors. Our findings highlight PNI as an important predictor of prognosis in hip fracture patients., (© The Author(s) 2024. Published by Oxford University Press on behalf of the British Geriatrics Society.

Background: Hip fractures are frequent injuries in older patients and are associated with high mortality rates. This study assessed the association between serum lactate level and 30-day mortality in older patients with unilateral hip fractures and examined the prognostic value of this association on the clinical outcomes of these patients., Methods: This retrospective, single-center study included patients aged ≥65 years admitted to the emergency department due to low-energy trauma and diagnosed with unilateral hip fracture upon admission. The additional inclusion criteria were patients with independent ambulation or walker or cane assistance before the injury, with available data on serum lactate levels on venous blood gas analysis, and who underwent surgery., Results: Among the 330 included patients, 30.9% experienced postoperative complications and 10.3% died within 30 days. Using a lactate cut-off value of 2 mmol/L to distinguish between living and deceased patients, the sensitivity and specificity were 41% and 88%, respectively. Multivariate logistic regression analysis revealed that high lactate and low albumin levels and male sex were associated with mortality., Conclusion: Identifying risk factors for mortality in geriatric patients with hip fractures is important. Male sex, low albumin levels, and particularly increased lactate levels were independent predictors of short-term mortality in these patients.

Introduction: Early surgery for hip fracture, within 48 hours of hospital admission, is effective in reducing mortality. However, the average preoperative waiting time for hip fractures in Japan is 4.5 days and the 1-year mortality rate after a hip fracture is 10% in Japan. This study aimed to investigate whether early surgery, within 48 hours, could reduce the 1-year mortality rate in patients with hip fractures in Japan., Methods: This cohort study involved 402 consecutive patients with hip fractures who underwent surgical treatment between January 2013 and September 2019. The exclusion criteria were an age of <60 years and in-hospital injury. A total of 389 patients were included in this study. The patients were divided into two groups: those who underwent early surgery within 48 hours of admission (early group) and those who di not undergo early surgery (delayed group). We compared patient characteristics and treatment outcomes between the 2 groups., Results: A comparison of patient characteristics revealed that the early group had lower hemoglobin levels (P=0.046), lower C-reactive protein levels ( P  = 0.031), lower numbers of patients with weekend hospitalization, lower numbers of patients with a history of using medications that may cause bleeding ( P  < 0.01), and who received general anaesthesia ( P  < 0.01). However, there were no significant differences with regard to the other variables between the 2 groups. A treatment outcome analysis showed that the early group had shorter waiting times for surgery ( P  < 0.01) and shorter stays in acute-care wards ( P  < 0.01). However there were no differences in the total hospital stay, Barthel index at discharge, home discharge rates, in-hospital mortality rates, and 1-year mortality., Conclusion: Our findings indicate that early surgery did not reduce the 1-year mortality rate in older patients with hip fractures in Japan., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: Femoral neck fractures (FNFs) in elderly patients are associated with major morbidity and mortality. The influence of postoperative discharge location on recovery and outcomes after arthroplasty for hip fractures is not well understood., Methods: A multisite retrospective cohort from 9 academic centers identified patients who had FNF treated with hemiarthroplasty or total hip arthroplasty between 2010 and 2019. Patients who had diagnoses of dementia, stroke, age > 80 years, or high energy fracture were excluded. Discharge location was identified, including home-based health services (HHS), inpatient rehabilitation (IPR), or a skilled nursing facility (SNF). Rates of reoperation, periprosthetic joint infection (PJI), and mortality were compared between cohorts. Multivariate logistic regressions were performed, adjusting for age, American Society of Anesthesiologists (ASA) score, body mass index, sex, and tobacco use. Statistical significance was defined as P < .05., Results: A total of 672 patients (315 HHS, 144 IPR, and 213 SNF) were included in this study. The average follow-up was 30 months. The SNF cohort was significantly older (P < .0001) with higher ASA scores (P < .0001) than the HHS cohort. In a logistic regression model adjusting for age, ASA score, and body mass index, the SNF cohort had higher mortality rates than the HHS cohort (P = .0296) and were more likely to have PJI within 90 days (odds ratio = 4.55, 95% confidence interval = 1.40, 4.74) and within 1 year (odds ratio = 3.08, 95% confidence interval = 1.08, 8.78). Time to PJI was significantly shorter in the SNF cohort (SNF 38 versus HHS 231 days, P = .0155). No differences were seen in dislocation or reoperation rates between the SNF and HHS cohorts. No differences were seen in complication rates between the IPR and HHS cohorts., Conclusions: Discharge to a SNF after arthroplasty for FNF is associated with increased mortality and higher rates of PJI. Hip fracture care pathways that uniformly discharge patients to SNFs may need to be re-evaluated, and surgeons should consider discharge to home with HHS when possible., (Copyright © 2024 Elsevier Inc.

Background: The impact of hip fracture on older adults is significant, including increased mortality, reduced activity levels and abilities and reduced quality of life。 Hip fractures often occur in the elderly and increase the risk of death. The purpose of this study is to analyze the risk factors associated with 28-day mortality in elderly patients with severe hip fractures using two models, XG Boost and multivariate logistic regression, and to compare the predictive value of the two models., Methods: MIMIC database is a powerful tool to provide clinical data to clinical researchers. The database was established in 2003 with funding from the National Institutes of Health by the Computational Physiology Laboratory at the Massachusetts Institute of Technology, Beth Israel Deaconess Medical Center (BIDMC) at Harvard Medical School, and Philips Medical. Patients with severe hip fractures in the elderly were included based on the MIMIC-IV database and were divided into a death group and a survival group based on the death 28 days after admission to the ICU. Baseline data differences between the two groups of patients were compared, and risk factors associated with 28-day mortality in severe elderly patients with hip fractures were analyzed using XG Boost and multivariate logistic regression models, respectively. The predictive power of the two models was compared using receiver operation characteristics curves., Results: 287 elderly patients with severe hip fractures were included, including 43 cases (15.0%) in the death group and 244 cases (85.0%) in the survival group. Logistic regression analysis showed that advanced age, male, congestive heart failure (CHF), chronic obstructive pulmonary disease (COPD), high sepsis-related organ failure (SOFA) score, high heart rate, high white blood cell count, high creatinine, high mean arterial pressure, and high hemoglobin levels were associated with 28-day mortality after admission to the ICU, while the higher the mean arterial pressure and the hemoglobin level, the lower the risk of death. Although the rate of using mechanical ventilation and receiving blood transfusion in the death group was higher than that in the survival group, neither of them reached statistical significance. The XG Boost model shows that the top 5 factors associated with 28-day mortality are Sequential organ failure score (SOFA) score (31 points), chronic heart failure (20 points), chronic structural pulmonary disease (18 points), age (17 points), and male (15 points). The higher the mean arterial pressure and the hemoglobin level, the lower the risk of death. The area under the ROC curve predicted by the multivariate logistic regression model for mortality risk was 0.729 (95% CI: 0.701-0.783), and the Jordan index was 0.412. The area under the ROC curve predicted by the XG Boost model for mortality risk was 0.804 (95% CI: 0.720-0.837), and the Jordan index was 0.492., Conclusion: The ability of the XG Boost model to predict the 28-day mortality risk in elderly patients with severe hip fractures is better than the multivariate logistic regression model, which will help healthcare professionals provide more support for elderly patients with hip fracture.

Background: Hip fractures constitute a major public health problem for older individuals. They are associated with functional deterioration, limited mobility, and increased mortality, while contributing to economic and social hardships that are compounded by a second hip fracture. With the aging US population and increasing rates of hip fractures, it is essential to understand factors surrounding subsequent contralateral hip fractures., Materials and Methods: This descriptive study was a retrospective review of patients 60 years and older who were identified in the institutional geriatric hip fracture database as having had an initial and subsequent contralateral hip fracture, with the second treated at our tertiary referral center., Results: The incidence of subsequent hip fracture was 13.2%. The mean time to second hip fracture was 3.5 years after the initial injury. The first fracture tended to be a femoral neck fracture, whereas the second injury was more likely to have an intertrochanteric pattern. There was a higher complication rate after a subsequent hip fracture. Patients taking osteoporosis and adjuvant medication prior to admission for the second fracture tended to have a lower 90-day mortality rate. Patients with a history of any fracture prior to the first hip fracture, with cancer, and with osteopenia had shorter intervals to the subsequent event., Conclusion: Subsequent hip fractures carry high morbidity and mortality rates. Steps should be taken after the initial injury to optimize outcomes in the case of a subsequent event. Patients discharged after initial hip fracture should be maintained with osteoporosis medication. [ Orthopedics . 2024;47(5):264-269.].

Objectives: Prognostic models have the potential to aid clinical decision-making after hip fracture. This systematic review aimed to identify, critically appraise, and summarize multivariable prediction models for mortality or other long-term recovery outcomes occurring at least 30 days after hip fracture., Study Design and Setting: MEDLINE, Embase, Scopus, Web of Science, and CINAHL databases were searched up to May 2023. Studies were included that aimed to develop multivariable models to make predictions for individuals at least 30 days after hip fracture. Risk of bias (ROB) was dual-assessed using the Prediction model Risk Of Bias ASsessment Tool. Study and model details were extracted and summarized., Results: From 5571 records, 80 eligible studies were identified. They predicted mortality in n = 55 studies/81 models and nonmortality outcomes (mobility, function, residence, medical, and surgical complications) in n = 30 studies/45 models. Most (n = 46; 58%) studies were published since 2020. A quarter of studies (n = 19; 24%) reported using 'machine-learning methods', while the remainder used logistic regression (n = 54; 68%) and other statistical methods (n = 11; 14%) to build models. Overall, 15 studies (19%) presented 18 low ROB models, all predicting mortality. Common concerns were sample size, missing data handling, inadequate internal validation, and calibration assessment. Many studies with nonmortality outcomes (n = 11; 37%) had clear data complexities that were not correctly modeled., Conclusion: This review has comprehensively summarized and appraised multivariable prediction models for long-term outcomes after hip fracture. Only 15 studies of 55 predicting mortality were rated as low ROB, warranting further development of their models. All studies predicting nonmortality outcomes were high or unclear ROB. Careful consideration is required for both the methods used and justification for developing further nonmortality prediction models for this clinical population., Competing Interests: Declaration of competing interest M.E.W. reports financial support was provided by Health Research Board.

Background: Persistent inflammation is associated with adverse health outcomes, but its impact on mortality has not been investigated previously among hip fracture patients. This article aims to investigate the influence of changes in levels of cytokines in the 2 months after a hip fracture repair on 5-year mortality., Methods: This is a prospective cohort study from the Baltimore Hip Studies (BHS) with 191 community-dwelling older men and women (≥65 years) who had recently undergone surgical repair of an acute hip fracture, with recruitment from May 2006 to June 2011. Plasma interleukin-6 (IL-6), soluble tumor necrosis factor alpha receptor1 (sTNFα-R1), and interleukin-1 receptor agonist (IL-1RA) were obtained within 22 days of admission and at 2 months. All-cause mortality over 5 years was determined. Logistic regression analysis tested the associations between the cytokines' trajectories and mortality over 5 years, adjusted for covariates (age, sex, education, body mass index, lower extremity physical activities of daily living, and Charlson comorbidity index)., Results: High levels of IL-6 and sTNFα-R1 at baseline with small or no decline at 2 months were associated with higher odds of 5-year mortality compared with those with lower levels at baseline and greater decline at 2 months after adjustment for age, and other potential confounders (OR = 4.71, p = 0.01 for IL-6; OR = 15.03, p = 0.002 for sTNFα-R1). Similar results that failed to reach significance were found for IL-1RA (OR = 2.40, p = 0.18). Those with higher levels of cytokines at baseline with greater decline did not have significantly greater mortality than the reference group, those with lower levels at baseline and greater decline., Conclusion: Persistent elevation of plasma IL-6 and sTNFα-R1 levels within the first 2 months after hospital admission in patients with hip fracture is associated with higher 5-year mortality. These patients may benefit from enhanced care and earlier intensive interventions to reduce the risk of death., (© 2024 The American Geriatrics Society.)

Purpose: Modular dual-mobility cups (MDMCs) have a lower risk for dislocation after total hip arthroplasty (THA). The primary aims of our study were to analyze implant survivorship and to determine complications, especially dislocation, and revision rates of primary THAs used for hip fracture patients and for revision THAs. Secondary aims were to evaluate mortality after MDMC surgery and to find out if introduction of MDMC at our institution (Kuopio University Hospital, Finland) have decreased dislocation rate., Methods: This retrospective cohort study consisted of 101 MDMC patients who were consecutively operated at our institution between April 1, 2018 and June 30, 2020. The implant survival rate, complications and mortality were evaluated with minimum of 2-year follow-up. Finnish Hospital Discharge Register was used to find out yearly dislocation rates following THA at our institution., Results: The cumulative estimate implant survival after MDMC in the primary THA group was 97% at 2 years, and in the revision THA group, it was 90% at 2 years. Dislocation was a rare complication in the primary THA group (1.4%), while it was common in revision THA group (12.9%). The cumulative estimate for mortality after MDMC in the primary THA group was 13% at 2 years, and in the revision group, it was also 13% at 2 years. The yearly number of patients who had re-hospitalization period due to THA dislocation decreased 46% after implementation of MDMC., Conclusion: Short-term survival and complication rates after MDMC were excellent after primary THA and moderate after revision THA. Implementation of MDMC THA for hip fracture patients seems to have effectively decrease dislocation rate during a short follow-up., (© 2024. The Author(s).)

Purpose: Despite the ongoing rise in hip fractures and the adverse effects of hearing impairment (HI) on increased mortality and morbidity, research addressing the influence of HI on mortality risk or complications in patients with hip fractures remains absent. This study aimed to analyze the effects of HI on mortality and treatment outcomes among patients with hip fracture., Methods: We retrospectively collected data from consecutive patients diagnosed with hip fractures between January 2007 and March 2022 who had auditory examination records. From the initially enrolled 265 patients, data for 58 with HI and 58 without HI (control group) were extracted using a 1:1 propensity score matching. The primary outcome included comparison of mortality rates, and the secondary outcome encompassed the comparison of postoperative medical and surgical complications., Results: The 1-year cumulative mortality rate was not significantly different between the HI and control groups, but the overall cumulative mortality rate was significantly higher in the HI than in the control group (63.0 % and 48.6, respectively; P = 0.046) in a follow-up period of up to 16 years. The HI group had a significantly higher incidence of "second hip fractures due to falls" than the control group (P = 0.016), although no differences in other medical and surgical complications were revealed., Conclusions: Awareness of the long-term risk of higher mortality when managing patients with hip fracture and HI is important. To reduce the risk of second hip fractures, paying more attention to fall prevention education and taking a more proactive approach, especially for those with HI., Competing Interests: Declaration of competing interest The authors, their immediate families, and any research foundations with which they are affiliated have not received any financial payments or other benefits from any commercial entity related to the subject of this article., (Copyright © 2024 Elsevier B.V.

Objective: To investigate the 1 year mortality after hip fractures in super advanced age patients and summarize the death associated risk factors in order to provide basis for targeted intervention countermeasures., Methods: The clinical data of 332 super advanced age patients with femoral neck or intertrochanteric fractures treated by hip replacement or intramedullary femoral nail fixation from January 2015 to January 2023 were retrospectively analyzed. There were 128 males and 204 females with the mean age of (92.2±2.5) years ranging from 90 to 103 years old. Among them, 92 cases died within 1 year after surgery. Correlation with the occurrence of death on age, gender, body mass index, fracture type, treatment method, timing of operation, preoperative hemoglobin and serum albumin level, operation time, combined medical diseases, pre-injury mobilityand American Society of Anesthesiology(ASA) classification were analyzed. The risk factors of death within 1 year after operation were screened by univariate analysis. The results were entered into the multivariate Logistic regression analysis, screening the high risk factors for 1 year mortality after hip fractures., Results: The mortality of super advanced age patients with hip fracture within 1 year after surgery accounted for 27.7%(92/332). Univariate analysis showed high body mass index, long interval from injury to surgery, low preoperative serum albumin levels, inability to walk independently before injury, accompanied by heart failure, pulmonary infection, obstructive pulmonary disease, stroke, and a higher proportion of ASA grades Ⅲ-Ⅳ. Multivariate Logistic regression analysis showed preoperative serum albumin below 30g g·L -1 [ OR =2.973, 95% CI (2.461, 5.344), P =0.039], inability to walk independently before injury [ OR =3.519, 95% CI (2.224, 5.413), P =0.018], heart function grade C-D[ OR =4.213, 95% CI (2.952, 6.99), P =0.021], pulmonary infection[ OR =3.927, 95% CI (2.187, 7.731), P =0.016] and ASA Ⅲ-Ⅳ[ OR =5.124, 95% CI (3.092, 8.235), P =0.032] were the independent risk factors for death within 1 year in super advanced age patients with hip fractures., Conclusion: Preoperative serum albumin below 30g.L-1, poor preinjury activity, heart function grade C-D, pulmonary infection, and ASA grade Ⅲ-Ⅳ are independent risk factors for postoperative mortality in super advanced age patients with hip fractures.

Importance: Most patients presenting with a hip fracture regardless of their comorbidities are surgically treated. A growing body of research states that a certain type of elderly patient could benefit more from a palliative approach., Objective: Identify the patient who would benefit most from a palliative care approach instead of a surgery., Design: Exploratory-matched retrospective cohort study between 2015 and 2021., Setting: Single Level 1 Trauma Center., Participants: There were 2240 hip fracture patients admitted to our institution between 2015 and 2021. Patients over 65 years old with intertrochanteric or femoral neck fractures could be included. A total of 129 patients opted for palliative care (Palliative Group = PG). This cohort was compared to a matched cohort (for age, sex and fracture type) who underwent surgery but died within three months of the procedure (Surgery Deceased Group = SDG) and another matched cohort who survived more than three months (Surgery Alive Group = SAG) following surgery., Main Outcomes and Measures: Medical charts were reviewed for patient demographics, autonomy level, level of care, neurocognitive disorders (NCD), fracture type, in-hospital data and outpatient death within three months of admission. Analysis was performed through univariate and multivariate models with SAS OnDemand for Academics (alpha 0.05)., Results: Patients in the PG (n = 129) were 88.2 ± 7.2 years old, 71.3% were females, and 61.2% had a femoral neck fracture. Patients in the SDG (n = 95) and SAG (n = 107) were well matched. The PG differed from the SDG (n = 95) and SAG (n = 107) regarding NCD (85.3% vs. 57.9% vs. 36.4%, p < 0.01) and the presence of Behavioral and psychological symptoms of dementia (BPSD) (19.4% vs. 5.3% vs. 3.7%, p < 0.01). There were more known heart failure (24.2% vs. 16.3%, p < 0.01) and Chronic Obstructive Pulmonary Disease (COPD) in the SDG group than in the PG group (26.6 vs. 14.7%, p = 0.02). Patients in the SAG have a significant lower rate of NCD (OR 2,7 (95%CI 1,5-5,0)), heart failure (OR 5,7 (95%CI 1,9-16,4)) and COPD (OR 2,8 (95%CI 1,2-6,3)) than other groups. Prefracture mobility, autonomy and living situation significantly differed between the groups. Median survival was six days in PG and 17 days in SDG. All groups lost autonomy and mobility. There were more complications in the SDG group than in the PG group. The end-of-care trajectory was death or hospice for most patients in the PG and SDG groups. More than 30% of the SAG group could not return home at discharge., Conclusion: The presence of an NCD and diminished prefracture autonomy strongly support counseling for palliative care. The high rate of complications when surgery is proposed for frail patients with multiple comorbidities suggests that the concept of palliative surgery needs to be revisited., (© 2024.

BACKGROUND It is unclear whether preoperative thyroid-stimulating hormone (TSH) level is correlated with long-term mortality in the elderly after hip fracture surgery. We aimed to assess the association between TSH levels and 3-year mortality in these patients. MATERIAL AND METHODS We enrolled patients aged 65 and above who had hip fracture surgery and thyroid function tests upon admission from 2018 to 2019. Patients were categorized based on TSH median value, quartiles, or thyroid function status. The median follow-up time was 3.1 years. Cox proportional hazards models were used to examine the correlation between TSH levels and mortality, adjusting for covariates. RESULTS Out of 799 eligible patients, 92.7% (741/799) completed the follow-up, with 20.6% (153/741) of those having died by the end of the follow-up. No statistically significant differences in mortality risks were found when stratified by TSH median value (HR 0.88, 95% CI 0.64-1.22, P=0.448) or quartiles (HR ranging from 0.90 to 1.13, P>0.05). Similarly, when categorized based on admission thyroid function status, patients who presented with hypothyroidism, subclinical hypothyroidism, hyperthyroidism, and subclinical hyperthyroidism upon admission did not demonstrate a statistically significant difference in mortality risk compared to those who were considered euthyroid (HR 1.34, 95% CI 0.72-2.49, P=0.359; HR 0.77, 95% CI 0.38-1.60, P=0.489; HR 1.15, 95% CI 0.16-8.30, P=0.890; HR 1.07, 95% CI 0.34-3.38, P=0.913, respectively). CONCLUSIONS Admission TSH is not significantly associated with 3-year mortality in geriatric patients after hip fracture surgery.

Hip fractures remain a substantial health concern, particularly among elderly individuals with osteoporosis, leading to high global mortality rates. This study aimed to analyze the association between body mass index (BMI) and postoperative mortality in patients who underwent surgery for hip fractures. A total of 680 patients treated at a single institution between January 2018 and December 2022 were included. Factors such as age, BMI, sex, Charlson Comorbidity Index (CCI), preoperative hemoglobin levels, American Society of Anesthesiologists score, anesthesia method, duration of surgery, and time from injury to surgery were assessed. Underweight status, male sex, higher CCI, and general anesthesia were significantly associated with 1-year and in-hospital mortality. Notably, underweight individuals exhibited a higher risk of mortality than normal-weight individuals, and female patients had lower mortality rates. This study underscores the importance of considering BMI, along with other demographic and clinical factors, in predicting postoperative mortality among patients with hip fractures, aiding the development of tailored management strategies to improve outcomes and reduce complications in this vulnerable patient population., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2024 the Author(s).

Introduction: Pulmonary hypertension (PHTN) is associated with increased morbidity and mortality in noncardiac surgery and elective surgery. This population of patients has a low physiological reserve and is prone to cardiac arrest as a result. This study aims to identify the impact that PHTN has on outcomes among geriatric hip fracture patients., Methods: A 3:1 propensity-score-matched retrospective case (PHTN)-control (no PHTN [N]) study of hip fracture patients from 2014 to 2022 was performed. Patients were matched utilizing propensity score matching of a validated geriatric trauma risk assessment tool (STTGMA). All patients were reviewed for hospital quality measures and outcomes. Comparative univariable and multivariable analyses were conducted between the two matched cohorts. A sub-analysis compared patients across PHTN severity levels (mild, moderate, severe) based on pulmonary artery systolic pressures (PASP) as measured by transthoracic echocardiogram., Results: PHTN patients (n = 67) experienced a higher rate of inpatient, 30-day, and 1-year mortality, major complications, and 90-day readmissions as compared to the N cohort (n = 201). PHTN patients with a PASP > 60 experienced a significantly higher rate of major complications, need for ICU, longer admission length, and worse 1-year functional outcomes. Pulmonary hypertension was found to be independently associated with a 3.5 × higher rate of 30-day mortality (p = 0.016), 2.7 × higher rate of 1-year mortality (p = 0.008), 2.5 × higher rate of a major inpatient complication (p = 0.028), and 1.2 × higher rate of 90-day readmission (p = 0.044)., Conclusion: Patients who had a prior diagnosis of pulmonary hypertension before sustaining their hip fracture experienced significantly worse inpatient and post-discharge outcomes. Those with a PASP > 60 mmHg had worse outcomes within the PHTN cohort. Providers must recognize these at-risk patients at the time of arrival to adjust care planning accordingly., Level of Evidence: III., (© 2024.

In this retrospective cohort study, we investigated: (1) The impact of comorbid chronic kidney disease (CKD) on postoperative mortality in patients with a hip fracture; (2) mortality variations by dialysis type, potentially indicating CKD stage; (3) the efficacy of different hip fracture surgical methods in reducing mortality for patients with CKD. This study included 25,760 patients from the Korean National Health Insurance Service-Senior cohort (2002-2019) who underwent hip fracture surgery. Participants were categorized as CKD and Non-CKD. Mortality rate was determined using a generalized linear model with a Poisson distribution. The effect size was presented as a hazard ratio (HR) through a Cox proportional-hazard model. During follow-up, we ascertained that 978 patients (3.8%) had CKD preoperatively. Compared to the Non-CKD group, the mortality risk (HR) in the CKD group was 2.17 times higher (95% confidence interval [CI], 1.99-2.37). In sensitivity analysis, the mortality risk of in patients who received peritoneal dialysis and hemodialysis was 6.21 (95% CI, 3.90-9.87) and 3.62 times (95% CI, 3.11-4.20) higher than that of patients who received conservative care. Mortality risk varied by surgical method: hip hemiarthroplasty (HR, 2.11; 95% CI, 1.86-2.40), open reduction and internal fixation (HR, 2.21; 95% CI, 1.94-2.51), total hip replacement (HR, 2.27; 95% CI, 1.60-3.24), and closed reduction and percutaneous fixation (HR, 3.08; 95% CI, 1.88-5.06). Older patients with CKD undergoing hip fracture surgery had elevated mortality risk, necessitating comprehensive pre- and postoperative assessments and management., (© 2024.

Background: Timing of surgery remains a topic of debate for hip fracture treatment in the geriatric patient population. The quality indicator "early surgery" was implemented in 2014 at the Department of Trauma Surgery of the University Hospitals Leuven to enhance timely operative treatment. In this follow-up study, we aim to evaluate the performance of this quality indicator, the clinical outcomes, and room for improvement., Methods: The charts of 1190 patients surgically treated for an acute hip fracture were reviewed between June 2017 and May 2022 at the University Hospitals Leuven. Primary endpoints were adherence to early surgery, defined as surgery within the next calendar day, and the evaluation of the reasons for deviating from this protocol. Secondary endpoints were length of stay (LOS); intensive care unit (ICU) admission and length of ICU stay; mortality after 30 days, 60 days, 90 days, and 6 months; and 90-day readmission rate. Pearson's Chi-square test and Mann-Whitney U test were used for data analysis., Results: One thousand eighty-four (91.1%) patients received early surgery versus 106 (8.9%) patients who received delayed surgery. The main reasons for surgical delay were the use of anticoagulants (33%), a general health condition not allowing safe surgery and/or existing comorbidities requiring workup prior to surgery (26.4%), and logistical reasons (17.9%). Patient delay and transfer from other hospitals were responsible for respectively 8.5% and 6.6% of delayed surgery. Early surgery resulted in a significantly shorter LOS and ICU stay (12 [8-25] vs. 18 [10-36] and 3 [2-6] vs. 7 [3-13] days, early vs. delayed surgery, respectively). No significant reduction was observed in ICU admission, mortality, and readmission rate., Conclusion: We have been able to maintain the early surgery hip fracture protocol in approximately 90% of the patients. Comorbidities and anticoagulant use were responsible for delayed surgery in the majority of the patients. Correct implementation of the existing protocol on anticoagulant use could lead to a one-third decrease in the number of delayed surgeries. Subsequently, since the LOS and ICU stay in the delayed surgery group were significantly longer, a further increase of early surgery will lower the current economic burden., (© 2024.

Objectives: To investigate the association between the Comprehensive Geriatric Assessment-based Frailty Index and adverse outcomes in older adult patients undergoing hip fracture surgery., Design: Retrospective cohort study., Setting: Academic Level 1 Trauma Center., Patients: All patients aged 65 or older who underwent surgical repair of a hip fracture between May 2018 and August 2020 were identified through institutional database review., Outcome Measures and Comparisons: Data including demographics, FI, injury presentation, and hospital course were collected. Patients were grouped by FI as nonfrail (FI < 0.21), frail (0.21 ≤ FI < 0.45), and severely frail (FI > 0.45). Adverse outcomes of these groups were compared using Kaplan Meier survival analysis. Risk factors for 1-year rehospitalization and 2-year mortality were evaluated using Cox hazard regression., Results: Three hundred sixteen patients were included, with 62 nonfrail, 185 frail, and 69 severely frail patients. The total population was on average 83.8 years old, predominantly white (88.0%), and majority female (69.9%) with an average FI of 0.33 (SD: 0.14). The nonfrail cohort was on average 78.8 years old, 93.6% white, and 80.7% female; the frail cohort was on average 84.5 years old, 92.4% white, and 71.9% female; and the severely frail cohort was on average 86.4 years old, 71.0% white, and 55.1% female. Rate of 1-year readmission increased with frailty level, with a rate of 38% in nonfrail patients, 55.6% in frail patients, and 74.2% in severely frail patients (P = 0.001). The same pattern was seen in 2-year mortality rates, with a rate of 2.8% in nonfrail patients, 36.7% in frail patients, and 77.5% in severely frail patients (P < 0.0001). Being classified as frail or severely frail exhibited greater association with mortality within 2 years than age, with hazard ratio of 17.81 for frail patients and 56.81 for severely frail patients compared with 1.19 per 5 years of age., Conclusions: Increased frailty as measured by the Frailty Index is significantly associated with increased 2-year mortality and 1-year hospital readmission rates after hip fracture surgery. Degree of frailty predicts mortality more strongly than age alone. Assessing frailty with the Frailty Index can identify higher-risk surgical candidates, facilitate clinical decision making, and guide discussions about goals of care with family members, surgeons, and geriatricians., Level of Evidence: Prognostic Level III.

Background: In patients who have hip fractures, treatment within 24 hours reduces mortality and complication rates. A similar relationship can be assumed for patients who have hip periprosthetic femoral fractures (PPFs) owing to the similar baseline characteristics of the patient populations. This monocentric retrospective study aimed to compare the complication and mortality rates in patients who had hip PPF treated within and after 24 hours., Methods: In total, 350 consecutive patients who had hip PPF in a maximum-care arthroplasty and trauma center between 2006 and 2020 were retrospectively evaluated. The cases were divided into 2 groups using a time to surgery (TTS) of 24 hours as the cutoff value. The primary outcome variables were operative and general complications as well as mortalities within 1 year., Results: Overall, the mean TTS was 1.4 days, and the 1-year mortality was 14.6%. The TTS ≤ 24 hours (n = 166) and TTS > 24 hours (n = 184) groups were comparable in terms of baseline characteristics and comorbidities. Surgical complications were equally frequent in the 2 groups (16.3 versus 15.2%, P = .883). General complications occurred significantly more often in the late patient care group (11.4 versus 28.3%, P < .001). In addition, the 30-day mortality (0.6 versus 5.5%, P = .012), and 1-year mortality (8.3 versus 20.5%, P = .003) rates significantly increased in patients who had TTS > 24 hours. Cox regression analysis yielded a hazard ratio of 4.385 (P < .001) for the TTS > 24 hours group., Conclusions: Prompt treatment is required for patients who have hip PPF to reduce mortality and overall complications., (Copyright © 2024 Elsevier Inc.

Purpose: Time to surgery from admission is one of the few variables known to influence outcome after a hip fracture. We reviewed our hip fracture database to determine correlation between delays to surgery and mortality in our elderly hip fracture population., Methods: Data on all hip fracture patients admitted to a large district hospital were prospectively collected between January 1989 and August 2021. Time of the injury, time of admission and time of surgery were recorded. Patients over 60 years old with a hip fracture requiring operative management were included. Patients with pathological fractures, those managed conservatively, and patients delayed for medical reasons were excluded. Surgical timing categories were divided into; under 12 h, 12-24 h, 24-72 h and over 72 h., Results: Time from admission to surgery was recorded for 10,659 patients, of these time of fall was available for 10,346 patients. Mean age was 82.2 years (sd 8.39) for the cohort and 30 day mortality was 6.20%. Odds of 30-day mortality was 1.43 (CI 1.057-1.988, p = 0.025) for delay to surgery from admission of over 12 h compared to under 12 h. Odds ratios for 30-day mortality were not significant at any other time threshold. The odds of 30-day mortality for delay to surgery from time of fall were 1.550 (CI 1.026-2.459, p = 0.048) at the 12 h threshold., Conclusion: This is the largest prospective study to date in elderly patients with hip fractures demonstrating a statistically significant increase in 30-day mortality with a delay to surgery over 12 h., (© 2024.

Background: Various factors contribute to the development of mortality and morbidity in hip fracture surgeries. This study aims to investigate the effects of modifiable factors such as the type of anesthesia, anesthesia management, surgical method, and timing of surgery on 30-day mortality rates, intensive care unit admissions, and complications., Methods: A total of 400 patients who underwent hip fracture surgery between January 2021 and December 2023 at a Training and Research Hospital were retrospectively analyzed. Patients were divided into two groups: those followed in the ward, named Group 1 (n=304), and those in the intensive care unit, named Group 2 (n=96). Recorded data included demographic characteristics, American Society of Anesthesiologists (ASA) physical status scores, types of comorbidities, anesthesia type, surgical method, surgical delay time, duration of surgery, blood transfusion requirements, and complications., Results: Patients in Group 2 had higher mean age, comorbidity, and mortality rates compared to Group 1 (p<0.001). In terms of types of comorbidities, the rate of intensive care unit admission was higher in patients with coronary artery disease and chronic renal failure (p<0.001). Mean surgical delay and length of hospital stay were also higher in Group 2 (p<0.001). In multivariate logistic regression analysis, age (p<0.001, Odds Ratio [OR]=1.91, Confidence Interval [CI]=1.046-1.137), ASA score (p<0.001, OR=3.872, CI=1.913-7.838), duration of surgical delay (p<0.001, OR=2.029, CI=1.365-3.017), surgical method (p=0.003, OR=2.003, C=1.258-3.188), and length of hospital stay (p=0.006, OR=1.147, CI=1.04-1.266) were determined as predictive factors for 30-day mortality., Conclusion: This study found that age, ASA classification, length of hospital stay, surgical method, and surgical delay were predictive factors for both morbidity and mortality. Among these, surgical delay time appears to be a modifiable parameter when all factors are considered.

Purpose: Treatment with direct-acting oral anticoagulants (DOACs) is increasing among hip-fracture patients, with accompanying safety concerns regarding spinal anesthesia (SA). The aim of this study was to investigate if DOAC use is associated with increased waiting time before surgery, increased mortality, or other adverse events., Methods: Registry data on surgically treated hip-fracture cases at a single hospital between 2015 and 2021 were analyzed. Multivariable regression analyses were performed with DOAC-status and choice of anesthesia as exposures, and waiting time, length of stay, transfusion, and mortality as outcomes., Results: 2885 cases were included, 467 patients (16%) were using DOACs. DOAC users were older (86.3 vs. 82.2 years, p < 0.001), had a higher Charlson Comorbidity Index (2.1 vs. 1.5, p < 0.001) and had longer median time to surgery than non-DOAC cases (36 h vs 17 h, p < 0.001). General anesthesia (GA) was used in 19.3% of DOAC patients and in 3.0% of non-DOAC patients. DOAC-patients had an increased risk of one-month mortality (Adjusted Odds Ratio (AOR) 1.6 (1.1-2.3)) and one-year mortality (AOR 1.4 (1.1-1.8)). There were no differences in risk of blood transfusion. Patients on DOAC operated under GA had a lower risk of one-year mortality (AOR 0.5 (0.3-0.9)), but a similar one-month mortality to DOAC-patients operated under SA., Conclusion: DOAC users had a longer waiting time to surgery, indicating postponement of surgery due to concerns of the safety of SA. The clinical practice should be changed to allow earlier surgery for DOAC patients., (© 2024. The Author(s).)

Background: The association between allogenic blood transfusions and all-cause mortality in surgically treated hip fracture patients with perioperative transfusion (STHFPT) remained unknown. The authors aim to introduce transfusion-related factors, new variables to develop, and validate models to predict mortality in these patients., Methods: A prospective multicenter cohort study was conducted with STHFPT hospitalized during January 2018 and June 2021. The database was divided into training cohort and validation cohort in a ratio of 70-30% using the randomization method. All participants received a minimum of 2-year follow-up and all participants' overall and eight time-specific survival status were recorded. Prediction models were developed using multivariate logistic regression and Cox regression for variable selection. Model performance was measured by determining discrimination, calibration, overall model performance or precision, and utility. Sensitivity analyses were performed to test robustness of the results., Results: A total of 7074 consecutive patients were prospectively screened and assessed for eligibility to participate. Finally, 2490 patients met our inclusion and exclusion criteria and 1743 (70%) patients were randomized to the training cohort and 747 (30%) to the validation cohort. The median duration of follow-up was 38.4 months (IQR 28.0-62.0). Our novel models highlight that preoperative transfusion is of significance for short-term mortality while mid-term outcomes are predominantly determined by severe complications, pulmonary complications, and advanced age. Our models showed high discriminative power, good calibration, and precision for mortality prediction in both training and validation cohorts, especially in short-term mortality prediction., Conclusions: The authors introduce transfusion-related factors, new variables to develop, and validate models to predict mortality with STHFPT. The models can be further tested and updated with the ultimate goal of assisting in optimizing individual transfusion strategy., (Copyright © 2024 The Author(s).

Background: In-hospital mortality following hip fractures is a significant concern, and accurate prediction of this outcome is crucial for appropriate clinical management. Nonetheless, there is a lack of effective prediction tools in clinical practice. By utilizing artificial intelligence (AI) and machine learning techniques, this study aims to develop a predictive model that can assist clinicians in identifying geriatric hip fracture patients at a higher risk of in-hospital mortality., Methods: A total of 52 707 geriatric hip fracture patients treated with surgery from 90 hospitals were included in this study. The primary outcome was postoperative in-hospital mortality. The patients were randomly divided into two groups, with a ratio of 7:3. The majority of patients, assigned to the training cohort, were used to develop the AI models. The remaining patients, assigned to the validation cohort, were used to validate the models. Various machine learning algorithms, including logistic regression (LR), decision tree (DT), naïve bayesian (NB), neural network (NN), eXGBoosting machine (eXGBM), and random forest (RF), were employed for model development. A comprehensive scoring system, incorporating 10 evaluation metrics, was developed to assess the prediction performance, with higher scores indicating superior predictive capability. Based on the best machine learning-based model, an AI application was developed on the Internet. In addition, a comparative testing of prediction performance between doctors and the AI application., Findings: The eXGBM model exhibited the best prediction performance, with an area under the curve (AUC) of 0.908 (95% CI: 0.881-0.932), as well as the highest accuracy (0.820), precision (0.817), specificity (0.814), and F1 score (0.822), and the lowest Brier score (0.120) and log loss (0.374). Additionally, the model showed favorable calibration, with a slope of 0.999 and an intercept of 0.028. According to the scoring system incorporating 10 evaluation metrics, the eXGBM model achieved the highest score (56), followed by the RF model (48) and NN model (41). The LR, DT, and NB models had total scores of 27, 30, and 13, respectively. The AI application has been deployed online at https://in-hospitaldeathinhipfracture-l9vhqo3l55fy8dkdvuskvu.streamlit.app/ , based on the eXGBM model. The comparative testing revealed that the AI application's predictive capabilities significantly outperformed those of the doctors in terms of AUC values (0.908 vs. 0.682, P <0.001)., Conclusions: The eXGBM model demonstrates promising predictive performance in assessing the risk of postoperative in-hospital mortality among geriatric hip fracture patients. The developed AI model serves as a valuable tool to enhance clinical decision-making., (Copyright © 2024 The Author(s). Published by Wolters Kluwer Health, Inc.)

Globally, hip fractures represent a significant and growing public health concern, particularly as the elderly population increases. The timing for surgery following hospitalization for hip fractures is a crucial indicator of acute quality care following recommended surgical guidelines of within two days to minimize complications and mortality. However, factors influencing delayed surgery and its outcomes remain debated. This study, used a national administrative database in South Korea, aimed to examine surgery performed within two days of hospitalization and investigate factors affecting delayed surgical interventions and associated outcomes. Of the hip fracture patients analyzed, 40.6% underwent surgery within two days of hospitalization. Factors associated with delayed surgery included: male patients (OR 1.190; 95% CI 1.022 ~ 1.385), medical aid beneficiary (OR 1.385; 95% CI 1.120 ~ 1.713), higher comorbidity index (OR 1.365; 95% CI 1.163 ~ 1.603, OR 1.612, 95% CI 1.327 ~ 1.958), weekends admission (OR 2.384; 95% CI 2.804 ~ 2.729), admission via outpatient department (OR 1.298, 95% CI 1.071 ~ 1.574). ORIF (OR 0.823, 95% CI 0.691 ~ 0.980) was associated with a significantly low risk of late surgery. While early surgery did not significantly impact in-hospital mortality or complications, it was associated with short and postoperative lengths of stay. This study underscores the need for prompt surgical intervention, particularly in high-risk patient populations, as well as highlights the importance of further research to elucidate the relationship between the timing of surgery and postoperative outcomes., (© 2024.

To investigate the relationship between admission blood urea nitrogen (BUN) levels and postoperative length of stay (LOS) in hip fracture (HF) patients. This retrospective study retrieved related data from the MIMIC-IV database, of which the laboratory variables were taken preoperatively. The patients were divided into 4 groups according to the BUN quartile levels. After exploring the nonlinear relationship between BUN and LOS by generalized additive model, their connection was further analyzed using the generalized linear models, quantile regression models, and interaction analysis. Receiver operating characteristic curve analysis and decision curve analysis were performed to evaluate its value in predicting first intensive care unit admission and in-hospital mortality. Totally 1274 patients with HF were enrolled in the study. There was a nonlinear relationship between BUN and LOS (P < .05). Besides, BUN was an independent predictor for LOS after adjusting different covariates in 3 models (P < .05). Age served as a significant interactor in this relationship (P < .05). Moreover, receiver operating characteristic curve and decision curve analysis revealed the predictive value of BUN for intensive care unit admission and in-hospital mortality in HF. Admission BUN level as a cost-effective and easy-to-collect biomarker is significantly related to LOS in patients with HF. It helps clinicians to identify potential high-risk populations and take effective preventions before surgery to reduce postoperative LOS., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2024 the Author(s).
