- Abstract
BACKGROUND: Surgeons in the Netherlands, Canada and the US participate in the FAITH trial (Fixation using Alternative Implants for the Treatment of Hip fractures). Dutch sites are managed and visited by a financed central trial coordinator, whereas most Canadian and US sites have local study coordinators and receive per patient payment. This study was aimed to assess how these different trial management strategies affected trial performance. METHODS: Details related to obtaining ethics approval, time to trial start-up, inclusion, and percentage completed follow-ups were collected for each trial site and compared. Pre-trial screening data were compared with actual inclusion rates. RESULTS: Median trial start-up ranged from 41 days (P25-P75 10-139) in the Netherlands to 232 days (P25-P75 98-423) in Canada (p = 0.027). The inclusion rate was highest in the Netherlands; median 1.03 patients (P25-P75 0.43-2.21) per site per month, representing 34.4% of the total eligible population. It was lowest in Canada; 0.14 inclusions (P25-P75 0.00-0.28), representing 3.9% of eligible patients (p < 0.001). The percentage completed follow-ups was 83% for Canadian and Dutch sites and 70% for US sites (p = 0.217). CONCLUSIONS: In this trial, a central financed trial coordinator to manage all trial related tasks in participating sites resulted in better trial progression and a similar follow-up. It is therefore a suitable alternative for appointing these tasks to local research assistants. The central coordinator approach can enable smaller regional hospitals to participate in multicenter randomized controlled trials. Circumstances such as available budget, sample size, and geographical area should however be taken into account when choosing a management strategy.

- Abstract
BACKGROUND: Clinical results for the treatment of displaced intra-articular calcaneal fractures are mainly expressed using disease-specific outcome scores, physical examination and radiographs. We hypothesized that plantar pressure and foot position analysis is a valuable tool in assessing foot function in patients with a unilateral displaced intra-articular calcaneal fracture treated percutaneously. MATERIALS AND METHODS: With a followup of at least one year, 21 patients with a unilateral displaced intra-articular calcaneal fracture treated percutaneously participated in the study. The pedobarographic measurements in the injured foot were compared with the contralateral control foot. Correlations between the ratios (injured/control) of plantar pressure and foot position variables and outcome scores, the physical exam items ratios, the fracture classification, and the radiological parameters were calculated. RESULTS: Statistically significant differences between the injured and the control foot were found for the weight distribution (p = 0.002), total contact time (p < 0.001), and the maximum pressure under the first metatarsal (p = 0.02) after a median followup of 18 months. Of all correlations calculated, only the heel time ratio correlated significantly with the heel width ratio (p = 0.004). CONCLUSION: Significant differences in plantar pressure distribution between the injured and uninjured foot were found, indicating that plantar pressure analysis and foot position analysis is an objective test to assess deviations in foot function. Plantar pressure data revealed limited correlation with outcome scores. Therefore, plantar pressure analysis should not be used instead of but in addition to established outcome scores.

- Abstract
Several naturally occurring food components or nonsteroidal anti-inflammatory drugs (NSAIDs) may reduce gastrointestinal cancer rates. Recently we have shown that dietary administration of such compounds enhanced the glutathione S-transferase (GST) enzyme activity and class alpha, mu and pi isoenzyme levels in the rat gastrointestinal tract. Elevation of the levels of GSTs, a family of biotransformation enzymes with many functions such as detoxification of carcinogens, might be one of the mechanism that lead to cancer prevention. We therefore investigated whether the anticarcinogens α-angelicalactone, α-tocopherol, β-carotene, coumarin, ellagic acid, flavone, indole-3-carbinol, d-limonene, oltipraz, phenethylisotheiocyanate (PEITC) and the sulphoraphane analogue compound-30 affect gastrointestinal rGSTT1-1 protein levels in male Wistar rats. rGSTT1-1 protein levels were determined in cytosolic fractions of liver and oesophageal-, gastric-, small intestinal- and colonic mucosa by densitometrical analyses of western blots after immunodetection with an anti-human GSTT1-1 monoclonal antibody, that cross-reacts with rGSTT1-1. In control Wistar rats, gastrointestinal rGSTT1-1 protein levels were highest in the liver and decreased in the order liver > stomach > colon > oesophagus > small intestine. Gastric rGSTT1-1 protein levels were enhanced by α-angelicalactone, α-tocopherol, coumarin, ellagic acid, oltipraz, PEITC and the sulphoraphane analogue compound-30. Oesophageal rGSTT1-1 protein levels were elevated by α-angelicalactone and coumarin, whereas colonic rGSTT1-1 protein levels were elevated by coumarin. Ellagic acid, on the other hand, reduced hepatic rGSTT1-1 protein levels to 53% of the control. In conclusion, dietary anticarcinogens are capable of inducing rGSTT1-1 protein levels in the rat gastrointestinal tract, and are most pronounced in the stomach. Enhanced rGSTT1-1 protein levels might lead to an increase of enzyme activity and to a more efficient detoxification of carcinogens and thus could contribute to prevention of carcinogenesis.

van Lieshout, EMM and Peters, WHM
- Abstract
Glutathione S-transferases (GSTs) are a family of enzymes involved in the detoxification of a wide range of chemicals including chemical carcinogens. Human cytosolic GSTs are divided into four major classes; α, μ, π, and θ. This study was performed to evaluate the influence of age and gender on the GST isoenzyme expression and glutathione (GSH) content in lymphocytes. Blood was collected from 124 healthy controls, which were divided into age groups of 20-40 years (21 females, 20 males), 40-60 years (20 females, 21 males) and 60-80 years (20 females, 22 males). Lymphocytes were isolated by density centrifugation on Histopaque-1077. After homogenization, cytosolic fractions were isolated. Herein, GST isoenzyme levels were determined by densitometrical analysis of western blots after immunodetection with monoclonal antibodies. Total GSH content was determined by high performance liquid chromatography after conjugation with monobromobimane. Spearman rank correlation and Wilcoxon rank sum tests were used for statistical evaluation. Lymphocytic GSTμ and π levels were not correlated with age or gender. GSTα was not detectable in lymphocytes. GSH contents were not different in males and females, but decreased with age in both males and females. In age group 60-80, GSH content was significantly lower as compared with age groups 20-40 and 40-60 in both sexes. Since high GSH is an essential factor in the detoxification of many compounds, these data indicate that the detoxification potential of the GSH/GST system in lymphocytes may decrease with age in man.

- Abstract
Objectives: Physician staffed Helicopter Emergency Medical Services (P-HEMS) care in the Netherlands has transitioned from predominantly trauma management to handling a variety of medical conditions. Relevant outcome parameters for Dutch P-HEMS research have not been previously defined. National consensus was sought to identify relevant long term patient outcome parameters, process outcome parameters and performance outcome parameters for Dutch P-HEMS care., Methods: This was a mixed methods Delphi consensus study. A list of potentially relevant outcome parameters was identified using a systematic literature review. These parameters were subsequently surveyed in a Delphi consensus study. Helicopter Emergency Medical Services physicians and relevant stakeholders were invited to participate in this Delphi survey, where they were allowed to suggest additional outcome parameters. Descriptive analysis was performed on all data sets., Results: Forty-nine potential outcome parameters for Dutch P-HEMS care were surveyed. Of 71 invited participants, 53 (75%), 40 (56%), and 20 (28%) participated in the first, second, and third round of the Delphi study, respectively. Consensus was reached on 25 (51%) of 49 outcome parameters as being important. These consisted of seven long term patient related outcome parameters, four short term patient related outcome parameters, five process outcome parameters and nine performance outcome parameters., Conclusions: In conclusion, this study identified 25 outcome parameters relevant for Dutch physician staffed HEMS care. These parameters should be considered when designing future studies and should be routinely collected for each dispatch if possible.

- Abstract
Background: Emergency Reflex Action Drills (ERADs) are meant to decrease stress-associated cognitive demand in high urgency situations. The aim of this study was to develop and test an ERAD for witnessed traumatic cardiac arrest (TCA), an event in which potentially reversible causes need to be systematically addressed and treated in a short period of time. We hypothesize that this ERAD (the TCA-Drill) helps ground Emergency Medical Services (EMS) nurses in overcoming performance decline during this specific high-pressure situation., Methods: This was a prospective, experimental one-group pre-post intervention study. Ground EMS nurses participated in a session of four simulated scenarios, with an in-between educational session to teach the TCA-Drill. Scenarios were video recorded, after which adherence and time differences were analyzed. Self-confidence on clinical practice was measured before and after the scenarios., Results: Twelve ground EMS nurses participated in this study. Overall median time to address reversible causes of TCA decreased significantly using the TCA-Drill (132 vs. 110 s; p = 0.030) compared with the conventional ALS strategy. More specifically, participants adhering to the TCA-Drill showed a significantly lower time needed for hemorrhage control (58 vs. 37 s; p = 0.012). Eight of 12 (67 %) ground EMS nurses performed the ERAD without protocol deviations. Reported self-confidence significantly increased on 11 of the 13 surveyed items., Conclusions: The use of an ERAD for TCA (the TCA-Drill) significantly reduces the time to address reversible causes for TCA without delaying chest compressions in a simulated environment and can be easily taught to ground EMS nurses and increases self-confidence., Implications for Clinical Practice: The use of an ERAD for TCA (the TCA-Drill can significantly reduce the time to address reversible causes for TCA without delaying chest compression. This drill can be easily taught to ground EMS nurses and increases their self-confidence in addressing TCA-patients., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024.

- Abstract
Introduction: Patients sustaining pulmonary contusion (PC) have a higher risk of complications and long-term respiratory difficulty. Computed tomography (CT) scans have a high sensitivity for PC. However, since PC develops over time, CT scans made directly post-trauma may underestimate the full extent of PC. This creates a need to better define in which PC-patients complications are more likely. The aim of this systematic review was to identify different classification systems of PC, and investigate the association between amount of PC and in-hospital outcomes., Methods: A systematic review was conducted in accordance with PRISMA guidelines. Studies reporting a classification system for PC after blunt thoracic trauma based on a CT scan were included. Outcomes were classification method of PC and the relation between classification and pulmonary complications and in-hospital outcomes., Results: Twenty studies were included. Total number of patients ranged from 49 to 148,140 patients. The most common classification system used was calculating the percentage of contused lung volume. Other classification methods were based on Blunt Pulmonary Contusion score-6 and -18, Abbreviated Injury Score and Thoracic Trauma Severity scores. Worse outcomes were generally associated with between > 18 to > 24% contusion volume., Discussion: The heterogeneity of currently available literature makes comparing classification methods challenging. The most common classification of PC was based on volumetric analysis. Calculating a percentage of PC as part of the total volume allows for the highest level of segmentation of lung parenchyma as compared to using BPC-6, BPC-18, or AIS. Contusion volume exceeding 18-24% was generally associated with worse outcomes., (© 2024. The Author(s).)

- Abstract
Purpose: This study aims to ascertain the prevalence of rib fractures and other injuries resulting from CPR and to compare manual with mechanically assisted CPR. An additional aim was to summarize the literature on surgical treatment for rib fractures following CPR., Design: Systematic review and meta-analysis., Data Sources: Embase, Medline Ovid, Cochrane Central, Web of Science, and Google Scholar., Review Methods: The databases were searched to identify studies reporting on CPR-related injuries in patients who underwent chest compressions for a non-traumatic cardiopulmonary arrest. Subgroup analysis was conducted to compare the prevalence of CPR-related injuries in manual versus mechanically assisted chest compressions. Studies reporting on surgery for CPR-related rib fractures were also reviewed and summarized., Results: Seventy-four studies reporting CPR-related injuries were included encompassing a total of 16,629 patients. Any CPR-related injury was documented in 60% (95% confidence interval [95% CI] 49-71) patients. Rib fractures emerged as the most common injury, with a pooled prevalence of 55% (95% CI 48-62). Mechanically assisted CPR, when compared to manual CPR, was associated with a higher risk ratio for CPR-related injuries of 1.36 (95% CI 1.17-1.59). Eight studies provided information on surgical stabilization of CPR-related rib fractures. The primary indication for surgery was the inability to wean from mechanical ventilation in the presence of multiple rib fractures., Conclusion: Rib fractures and other injuries frequently occur in patients who undergo CPR after a non-traumatic cardiopulmonary arrest, especially when mechanical CPR is administered. Surgical stabilization of CPR-related rib fractures remains relatively uncommon., Level of Evidence: Level III, systematic review and meta-analysis., (© 2024. The Author(s).)

- Abstract
Introduction: Severely injured patients are often incapacitated to provide informed consent for clinical studies. Deferred consent could facilitate unbiased enrollment in studies involving these patients. Little is known about how healthcare professionals (HCPs) perceive deferred consent and how this impacts patient enrollment. The aim of this study was to identify factors that could influence HCPs decision-making during recruitment of patients for interventional studies in (pre)hospital emergency trauma research., Methods: This was a qualitative study in which physicians and nurses working in prehospital or in-hospital care were interviewed using a semi-structured interview guide. Interviews were audio-recorded, transcribed, and analyzed according to thematic analysis as described by Braun and Clarke., Results: Ten semi-structured interviews were conducted with six physicians and four nurses. Eight themes were identified as being relevant consent related factors influencing HCPs' decision-making during patient recruitment in studies using deferred consent: (1) HCPs' lack of knowledge; (2) Patients' and proxies' inability to be informed; (3) Practical (im)possibilities for informed consent; (4) Nature of intervention; (5) HCPs' personal beliefs; (6) Importance of emergency care research; (7) HCPs' trust in legal base; and (8) Communication and collaboration., Conclusions: Eight consent-related factors influencing HCPs' decision making were identified. Insufficient knowledge about consent procedures among HCPs leads to significant negative attitudes towards deferred consent., Competing Interests: Declaration of competing interest None of the authors have any conflicts of interest to declare., (Copyright © 2024.

- Abstract
Background: The proportion of Open Pelvic fractures in the paediatric population is relatively high. While operative fixation is the primary approach for managing Open Pelvic fractures in adults, there is limited literature on treatment outcomes in Children, particularly regarding long-term musculoskeletal, neurological, and urogenital function., Methods: This multicentre case series included paediatric patients (<18 years old) with Open Pelvic ring fractures treated at one of two major trauma centres in the Netherlands between January 1, 2001 and December 31, 2021. Data collection involved clinical records and long-term assessments, including musculoskeletal function, growth disorders, urogenital function, sexual dysfunction, and sensory motor function., Results: A total of 11 patients were included, primarily females (73 %), with a median age at trauma of 12 years (P
25 -P75 7-14). Most patients had unstable Pelvic ring fractures resulting from high-energy trauma. Surgical interventions were common, with external fixation as the main initial surgical approach ( n = 7, 70 %). Complications were observed in eight (73 %) patients. Musculoskeletal function revealed a range of issues in the lower extremity, daily activities, and mental and emotional domain. Long-term radiologic follow-up showed high rates of Pelvic malunion ( n = 7, 64 %). Neurological function assessment showed motor and sensory function impairment in a subset of patients. Urogenital function was moderately affected, and sexual dysfunction was limited with most respondents reporting no issues., Conclusion: Paediatric Open Pelvic fractures are challenging injuries associated with significant short-term complications and long-term musculoskeletal and urogenital issues. Further research is needed to develop tailored treatment strategies and improve outcomes of these patients., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2024 The Authors.)- Published

- Abstract
Introduction: Health care patient records have been digitalised the past twenty years, and registries have been automated. Missing registrations are common, and can result in selection bias., Objective: To assess the prevalence and characteristics of missed registrations in a Dutch regional trauma registry., Methods: An automatically generated trauma registry export was done for ten out of eleven hospitals in trauma region Southwest Netherlands, between June 1 and August 31, 2020. Second, lists were checked for being falsely flagged as 'non-trauma'. Finally, a list was generated with trauma tick box flagged as 'trauma' but were not automatically in the export due to administrative errors. Automated and missed registration datasets were compared on patient characteristics and logistic regression models were run with random intercepts and missed registration as outcome variable on the complete dataset., Results: A total of 2,230 automated registrations and 175 (7.3 %) missed registrations were included for the Dutch National Trauma Registry, ranging from 1 to 14 % between participating hospitals. Patients of the missed registration dataset had characteristics of a higher level of care, compared with patients of automated registrations. Level of trauma care (level II OR 0.464 95 % CI 0.328-0.666, p < 0.001; level III OR 0.179 95 % CI 0.092-0.325, p < 0.001), major trauma (OR 2.928 95 % CI 1.792-4.65, p < 0.001), ICU admission (OR 2.337 95 % CI 1.792-4.650, p < 0.001), and surgery (OR 1.871 95 % CI 1.371-2.570, p < 0.001) were potential predictors for missed registrations in multivariate logistic regression analysis., Conclusion: Missed registrations occur frequently and the rate of missed registrations differs greatly between hospitals. Automated and missed registration datasets display differences related to patients requiring more intensive care, which held for the major trauma subset. Checking for missed registrations is time consuming, automated registration lists need a human touch for validation and to be complete., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: All authors have no financial and personal relationships with other people or organizations that could inappropriately influence (bias) the submitted manuscript ‘Missing patients in a Dutch regional trauma registry: Prevalence and epidemiology’., (Copyright © 2024 The Author(s).

- Abstract
Proximal femoral fractures in frail patients have a poor prognosis. Despite the high mortality, little is known about the quality of dying (QoD) while this is an integral part of palliative care and could influence decision making on nonoperative- (NOM) or operative management (OM). To identify the QoD in frail patients with a proximal femoral fracture. Data from the prospective FRAIL-HIP study, that studied the outcomes of NOM and OM in institutionalized older patients ≥70 years with a limited life expectancy who sustained a proximal femoral fracture, was analyzed. This study included patients who died within the 6-month study period and whose proxies evaluated the QoD. The QoD was evaluated with the Quality of Dying and Death (QODD) questionnaire resulting in an overall score and 4 subcategory scores (Symptom control, Preparation, Connectedness, and Transcendence). In total 52 (64% of NOM) and 21 (53% of OM) of the proxies responded to the QODD. The overall QODD score was 6.8 (P
25 -P75 5.7-7.7) (intermediate), with 34 (47%) of the proxies rating the QODD 'good to almost perfect'. Significant differences in the QODD scores between groups were not noted (NOM; 7.0 (P25 -P75 5.7-7.8) vs OM; 6.6 (P25 -P75 6.1-7.2), P = .73). Symptom control was the lowest rated subcategory in both groups. The QoD in frail older nursing home patients with a proximal femoral fracture is good and humane. QODD scores after NOM are at least as good as OM. Improving symptom control would further increase the QoD., 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.- Published

- Abstract
Background: While current preoperative and postoperative assessment of the fractured and surgically reconstructed calcaneus relies on computed tomography (CT)-imaging, there are no established methods to quantify calcaneus morphology on CT-images. This study aims to develop a semi-automated method for morphological measurements of the calcaneus on three-dimensional (3D) models derived from CT-imaging., Methods: Using CT data, 3D models were created from healthy, fractured, and surgically reconstructed calcanei. Böhler's angle (BA) and Critical angle of Gissane (CAG) were measured on conventional lateral radiographs and corresponding 3D CT reconstructions using a novel point-based method with semi-automatic landmark placement by three observers. Intraobserver and interobserver reliability scores were calculated using intra-class correlation coefficient (ICC). In addition, consensus among observers was calculated for a maximal allowable discrepancy of 5 and 10 degrees for both methods., Results: Imaging data from 119 feet were obtained (40 healthy, 39 fractured, 40 reconstructed). Semi-automated measurements on 3D models of BA and CAG showed excellent reliability (ICC: 0.87-1.00). The manual measurements on conventional radiographs had a poor-to-excellent reliability (ICC: 0.22-0.96). In addition, the percentage of consensus among observers was much higher for the 3D method when compared to conventional two-dimensional (2D) measurements., Conclusions: The proposed method enables reliable and reproducible quantification of calcaneus morphology in 3D models of healthy, fractured and reconstructed calcanei., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://qims.amegroups.com/article/view/10.21037/qims-24-142/coif).

Purpose: The aim of this study was to provide a comprehensive overview of (preoperative and geriatric) diagnostic testing, abnormal diagnostic tests and their subsequent interventions, and clinical relevance in frail older adults with a hip fracture., Methods: Data on clinical consultations, radiological, laboratory, and microbiological diagnostics were extracted from the medical files of all patients included in the FRAIL-HIP study (inclusion criteria: hip fracture, > 70 years, living in a nursing home with malnourishment/cachexia and/or impaired mobility and/or severe co-morbidity). Data were evaluated until hospital discharge in nonoperatively treated patients and until surgery in operatively treated patients., Results: A total of 172 patients (88 nonoperative and 84 operative) were included, of whom 156 (91%) underwent laboratory diagnostics, 126 (73%) chest X-rays, and 23 (13%) CT-scans. In 153/156 (98%) patients at least one abnormal result was found in laboratory diagnostics. In 82/153 (50%) patients this did not result in any additional diagnostics or (pharmacological) intervention. Abnormal test results were mentioned as one of the deciding arguments for operative delay (> 24 h) for 10/84 (12%) patients and as a factor in the decision between nonoperative and operative treatment in 7/172 (4%) patients., Conclusion: A large number and variety of diagnostics were performed in this patient population. Abnormal test results in laboratory diagnostics were found for almost all patients and, in majority, appear to have no direct clinical consequences. To prevent unnecessary diagnostics, prospective research is required to evaluate the clinical consequences and added value of the separate elements of preoperative diagnostic testing and geriatric assessment in frail hip fracture patients., (© 2024.

- Abstract
Background: Fracture-related infection is a serious complication after trauma. CERAMENT® G combines dead-space management with local release of gentamicin in a single-stage procedure. Bacterial resistance against antibiotics is increasing. The local effect of CERAMENT® G on bacteria resistant to systemically administered gentamicin is unknown., Questions/purposes: (1) What is the in vitro elution pattern of gentamicin from CERAMENT® G using a full washout model? (2) What is the in vitro antimicrobial activity (zone of inhibition) of CERAMENT® G against bacterial isolates found in fracture-related infection with different susceptibility levels toward gentamicin?, Methods: Elution of gentamicin from CERAMENT® G was determined in vitro over a period of 2 months. Elution experiments were performed in fivefold, with gentamicin being sampled in threefold at 19 different timepoints within 2 months. Antimicrobial activity was determined using the four most-frequently cultured bacterial species found in fracture-related infection: Staphylococcus aureus, Staphylococcus epidermidis, Pseudomonas aeruginosa, and Enterobacter cloacae . For each of the species, four different isolates with a different susceptibility to gentamicin were used. According to the European Committee on Antimicrobial Susceptibility Testing, the susceptibility of each isolate was classified into four different groups: fully susceptible (minimum inhibitory concentration 0.064 to 4 mg/L), minimally resistant (minimum inhibitory concentration 4 to 16 mg/L), moderately resistant (minimum inhibitory concentration 8 to 96 mg/L), and highly resistant (minimum inhibitory concentration 24 to 1024 mg/L), depending on each organism. The antimicrobial activity of CERAMENT® G was determined according to the European Committee on Antimicrobial Susceptibility Testing disk protocol. The experiment was performed in fivefold for each isolate. The zone of inhibition was compared between each bacterial isolate and within each of the four separate species. Nonlinear regression statistics were calculated between the zone of interest and logarithmic minimum inhibitory concentration for each bacterial species., Results: After 24 hours, 95% of all available gentamicin was eluted, and gentamicin was still detectable after 2 months. CERAMENT® G showed antimicrobial activity against all bacterial species; only S taphylococcus aureus (with a minimum inhibitory concentration > 1024 mg/L) was not susceptible. The zone of interest of the different bacterial isolates was correlated with the logarithmic minimum inhibitory concentration., Conclusion: CERAMENT® G offers a bone substitute capable of releasing high levels of gentamicin within a short period of time. This study shows that CERAMENT® G has antimicrobial activity against bacterial isolates that are resistant to gentamicin when systemically administered. This finding raises the question of whether European Committee on Antimicrobial Susceptibility Testing cutoff points for systemic application are useful for the use of local CERAMENT® G. Standardized experiments to determine local antibiotic antimicrobial activity in fracture-related infection treatment are needed to form guidelines for the use of local antibiotics and ultimately improve fracture-related infection treatment., Clinical Relevance: Local concentrations of gentamicin with CERAMENT® G are much higher than when systemically administered. It seems effective against certain bacterial strains that are not affected by systemically reachable concentrations of gentamicin. CERAMENT® G might still be effective when bacteria that are resistant to systemically administered concentrations of gentamicin are occulated from patients with fracture-related infection., Competing Interests: Each author certifies that there are no funding or commercial associations (consultancies, stock ownership, equity interest, patent/licensing arrangements, etc.) that might pose a conflict of interest in connection with the submitted article related to the author or any immediate family members.

- Abstract
Background: Rib fracture nonunion is a probable cause of chronic pain following chest trauma, although its prevalence remains unknown. The aims of this study were to determine rib fracture nonunion prevalence following nonoperative management and to determine if presence of nonunion was associated with the number of rib fractures, or the rib fracture classification of anatomical location, type, and displacement., Methods: This multicenter prospective cohort study included trauma patients with three or more fractured ribs but without a flail segment, who participated in the nonoperative management group of the FixCon trial between January 2019 and June 2022. The number and classification of rib fractures were assessed on trauma chest CT. Chest CTs conducted six months post-trauma were evaluated for the presence of nonunion. Radiological characteristics of nonunions were compared with normally healed rib fractures using the Mann-Whitney U, χ
2 test, and Fisher's exact test as appropriate. A generalized linear model adjusted for multiple observations per patient when assessing the associations between nonunion and fracture characteristics., Results: A total of 68 patients were included with 561 post-traumatic fractures in 429 ribs. Chest CT after six months revealed nonunions in 67 (12 %) rib fractures in 29 (43 %) patients with a median of 2 (P25 -P75 1-3) nonunions per patient. Nonunion was most commonly observed in ribs seven to 10 (20-23 %, p < 0.001, adjusted p = 0.006). Nonunion occurred in 14 (5 %) undisplaced, 22 (19 %) offset, and 20 (23 %) displaced rib fractures (p < 0.001). No statistically significant association between rib fracture type and nonunion was found., Conclusions: Forty-three percent of patients with multiple rib fractures had radiographic nonunion six months after trauma. Fractures in ribs seven to 10 and dislocated fractures had an increased risk of rib fracture nonunion., Competing Interests: Declaration of competing interest none., (Copyright © 2024 The Author(s).

- Abstract
Background and Purpose: Recent research has highlighted non-operative management (NOM) as a viable alternative for frail older adults with hip fractures in the final phase of life. This study aims to guide Dutch physicians and hospitals nationwide in a standardised implementation of shared decision-making regarding surgery or NOM in selected frail older adults with a hip fracture., Methods and Analysis: The patient population for implementation includes frail older adults aged ≥70 years with an acute proximal femoral fracture, nursing home care or a similar level of care elsewhere and at least one additional criterion (ie, malnutrition, severe mobility impairment or ASA≥4). The 2-year implementation study will be conducted in four phases. In phases 1 and 2, barriers and facilitators for implementation will be identified and an implementation protocol, educational materials and patient information will be developed. Phase 3 will involve an implementation pilot in 14 hospitals across the Netherlands. The protocol and educational material will be improved based on healthcare provider and patient experiences gathered through interviews. Phase 4 will focus on upscaling to nationwide implementation and the effect of the implementation on NOM rate will be measured using data from the Dutch Hip Fracture Audit., Ethics and Dissemination: The study was exempted by the local Medical Research Ethics Committee (MEC-2023-0270, 10 May 2023) and Medical Ethics Committee United (W23.083, 26 April 2023). The study's results will be submitted to an open access international peer-reviewed journal. Its protocols, tools and results will be presented at several national and international academic conferences of relevant orthogeriatric (scientific) associations., Trial Registration Number: NCT06079905 ., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

- Abstract
Background: The likelihood of return of spontaneous circulation with conventional advanced life support is known to have an exponential decline and therefore neurological outcome after 20 min in patients with a cardiac arrest is poor. Initiation of venoarterial ExtraCorporeal Membrane Oxygenation (ECMO) during resuscitation might improve outcomes if used in time and in a selected patient category. However, previous studies have failed to significantly reduce the time from cardiac arrest to ECMO flow to less than 60 min. We hypothesize that the initiation of Extracorporeal Cardiopulmonary Resuscitation (ECPR) by a Helicopter Emergency Medical Services System (HEMS) will reduce the low flow time and improve outcomes in refractory Out of Hospital Cardiac Arrest (OHCA) patients., Methods: The ON-SCENE study will use a non-randomised stepped wedge design to implement ECPR in patients with witnessed OHCA between the ages of 18-50 years old, with an initial presentation of shockable rhythm or pulseless electrical activity with a high suspicion of pulmonary embolism, lasting more than 20, but less than 45 min. Patients will be treated by the ambulance crew and HEMS with prehospital ECPR capabilities and will be compared with treatment by ambulance crew and HEMS without prehospital ECPR capabilities. The primary outcome measure will be survival at hospital discharge. The secondary outcome measure will be good neurological outcome defined as a cerebral performance categories scale score of 1 or 2 at 6 and 12 months., Discussion: The ON-SCENE study focuses on initiating ECPR at the scene of OHCA using HEMS. The current in-hospital ECPR for OHCA obstacles encompassing low survival rates in refractory arrests, extended low-flow durations during transportation, and the critical time sensitivity of initiating ECPR, which could potentially be addressed through the implementation of the HEMS system. When successful, implementing on-scene ECPR could significantly enhance survival rates and minimize neurological impairment., Trial Registration: Clinicaltyrials.gov under NCT04620070, registration date 3 November 2020., (© 2024.

- Abstract
Background/Objectives: Severe traumatic brain injury (TBI) is a frequent cause of morbidity and mortality worldwide. In the Netherlands, suspected TBI is a criterion for the dispatch of the physician-staffed helicopter emergency medical services (HEMS) which are operational 24 h per day. It is unknown if patient outcome is influenced by the time of day during which the incident occurs. Therefore, we investigated the association between the time of day of the prehospital treatment of severe TBI and 30-day mortality. Methods: A retrospective analysis of prospectively collected data from the BRAIN-PROTECT study was performed. Patients with severe TBI treated by one of the four Dutch helicopter emergency medical services were included and followed up to one year. The association between prehospital treatment during day- versus nighttime, according to the universal daylight period, and 30-day mortality was analyzed with multivariable logistic regression. A planned subgroup analysis was performed in patients with TBI with or without any other injury. Results: A total of 1794 patients were included in the analysis, of which 1142 (63.7%) were categorized as daytime and 652 (36.3%) as nighttime. Univariable analysis showed a lower 30-day mortality in patients with severe TBI treated during nighttime (OR 0.74, 95% CI 0.60-0.91, p = 0.004); this association was no longer present in the multivariable model (OR 0.82, 95% CI 0.59-1.16, p = 0.262). In a subgroup analysis, no association was found between mortality rates and the time of prehospital treatment in patients with combined injuries (TBI and any other injury). Patients with isolated TBI had a lower mortality rate when treated during nighttime than when treated during daytime (OR 0.51, 95% CI 0.34-0.76, p = 0.001). Within the whole cohort, daytime versus nighttime treatments were not associated with differences in functional outcome defined by the Glasgow Outcome Scale. Conclusions: In the overall study population, no difference was found in 30-day mortality between patients with severe TBI treated during day or night in the multivariable model. Patients with isolated severe TBI had lower mortality rates at 30 days when treated at nighttime.

- Abstract
Objective: This study aimed to provide population based trends in incidence rate, hospital length of stay (HLOS), trauma mechanism, and costs for healthcare and lost productivity of subtrochanteric femur fractures in the Netherlands., Methods: Data on patients with subtrochanteric femur fractures sustained between January 1, 2000 and December 31, 2019 were extracted from the National Medical Registration of the Dutch Hospital Database. Incidence rates, HLOS, health care and productivity costs were calculated in sex- and age-specific groups., Results: A total of 14,399 patients sustained a subtrochanteric fracture in the 20-year study period. Incidence rates in the entire population dropped by 15.5 % from 4.5 to 3.8 per 100,000 person years (py). This decline was larger in women (6.4 to 5.2 per 100,000 py, -19.8 %) than in men (2.6 to 2.5 per 100,000 py, -4.0 %). HLOS declined by 62.5 % from a mean of 21.6 days in 2000-2004 to 8.1 days in 2015-2019. Subtrochanteric fractures were associated with total annual costs of €15.5 M, of which 91 % (€14.1 M) were health care costs and €1.3 M were costs due to lost productivity. Mean healthcare costs per case were lower in men (€16,394) than in women (€23,154)., Conclusion: The incidence rates and HLOS of subtrochanteric fractures in the Netherlands have decreased in the 2000-2019 study period and subtrochanteric fractures are associated with a relatively small total annual cost of €15.5 M. Increasing incidence rates and a bimodal age distribution, described in previous studies from other European countries, were not found in the Dutch population., Competing Interests: Declaration of competing interest Miliaan L.

- Abstract
Background: Over the last two decades, the acute management of rib fractures has changed significantly. In 2021, the Chest Wall injury Society (CWIS) began recognizing centers that epitomize their mission as CWIS Collaborative Centers. The primary aim of this study was to determine the resources, surgical expertise, access to care, and institutional support that are present among centers., Methods: A survey was performed including all CWIS Collaborative Centers evaluating the resources available at their hospital for the treatment of patients with chest wall injury. Data about each chest wall injury center care process, availability of resources, institutional support, research support, and educational offerings were recorded., Results: Data were collected from 20 trauma centers resulting in an 80% response rate. These trauma centers were made up of 5 international and 15 US-based trauma centers. Eighty percent (16 of 20) have dedicated care team members for the evaluation and management of rib fractures. Twenty-five percent (5 of 20) have a dedicated rib fracture service with a separate call schedule. Staffing for chest wall injury clinics consists of a multidisciplinary team: with attending surgeons in all clinics, 80% (8 of 10) with advanced practice providers and 70% (7 of 10) with care coordinators. Forty percent (8 of 20) of centers have dedicated rib fracture research support, and 35% (7 of 20) have surgical stabilization of rib fracture (SSRF)-related grants. Forty percent (8 of 20) of centers have marketing support, and 30% (8 of 20) have a web page support to bring awareness to their center. At these trauma centers, a median of 4 (1-9) surgeons perform SSRFs. In the majority of trauma centers, the trauma surgeons perform SSRF., Conclusion: Considerable similarities and differences exist within these CWIS collaborative centers. These differences in resources are hypothesis generating in determining the optimal chest wall injury center. These findings may generate several patient care and team process questions to optimize patient care, patient experience, provider satisfaction, research productivity, education, and outreach., Level of Evidence: Therapeutic/Care Management; Level V., (Copyright © 2023 Wolters Kluwer Health, Inc.

- Abstract
Purpose: Surgical stabilization of rib fractures (SSRF) improves outcomes in certain patient populations. The Chest Wall Injury Society (CWIS) began a new initiative to recognize centers who epitomize their mission as CWIS Collaborative Centers (CWIS-CC). We sought to describe incidence and epidemiology of SSRF at our institutions., Methods: A retrospective registry evaluation of all patients (age > 15 years) treated at international trauma centers from 1/1/20 to 7/30/2021 was performed. Variables included: age, gender, mechanism of injury, injury severity score, abbreviated injury severity score (AIS), emergency department disposition, length of stay, presence of rib/sternal fractures, and surgical stabilization of rib/sternal fractures. Classification and regression tree analysis (CART) was used for analysis., Results: Data were collected from 9 centers, 26,084 patient encounters. Rib fractures were present in 24% (n = 6294). Overall, 2% of all patients underwent SSRF and 8% of patients with rib fractures underwent SSRF. CART analysis of SSRF by AIS-Chest demonstrated a difference in management by age group. AIS-Chest 3 had an SSRF rate of 3.7, 7.3, and 12.9% based on the age ranges (16-19; 80-110), (20-49; 70-79), and (50-69), respectively (p = 0.003). AIS-Chest > 3 demonstrated an SSRF rate of 9.6, 23.3, and 39.3% for age ranges (16-39; 90-99), (40-49; 80-89), and (50-79), respectively (p = 0.001)., Conclusion: Anticipated rate of SSRF can be calculated based on number of rib fractures, AIS-Chest, and age. The disproportionate rate of SSRF in patients age 50-69 with AIS-Chest 3 and age 50-79 with AIS-Chest > 3 should be further investigated, as lower frequency of SSRF in the other age ranges may lead to care inequalities., (© 2023.

- Abstract
Background: Severe traumatic brain injury is a leading cause of morbidity and mortality among young people around the world. Prehospital care focuses on the prevention and treatment of secondary brain injury and commonly includes tracheal intubation after induction of general anesthesia. The choice of induction agent in this setting is controversial. This study therefore investigated the association between the chosen induction medication etomidate versus S(+)-ketamine and the 30-day mortality in patients with severe traumatic brain injury who received prehospital airway management in the Netherlands., Methods: This study is a retrospective analysis of the prospectively collected observational data of the Brain Injury: Prehospital Registry of Outcomes, Treatments and Epidemiology of Cerebral Trauma (BRAIN-PROTECT) cohort study. Patients with suspected severe traumatic brain injury who were transported to a participating trauma center and who received etomidate or S(+)-ketamine for prehospital induction of anesthesia for advanced airway management were included. Statistical analyses were performed with multivariable logistic regression and inverse probability of treatment weighting analysis., Results: In total, 1,457 patients were eligible for analysis. No significant association between the administered induction medication and 30-day mortality was observed in unadjusted analyses (32.9% mortality for etomidate versus 33.8% mortality for S(+)-ketamine; P = 0.716; odds ratio, 1.04; 95% CI, 0.83 to 1.32; P = 0.711), as well as after adjustment for potential confounders (odds ratio, 1.08; 95% CI, 0.67 to 1.73; P = 0.765; and risk difference 0.017; 95% CI, -0.051 to 0.084; P = 0.686). Likewise, in planned subgroup analyses for patients with confirmed traumatic brain injury and patients with isolated traumatic brain injury, no significant differences were found. Consistent results were found after multiple imputations of missing data., Conclusions: The analysis found no evidence for an association between the use of etomidate or S(+)-ketamine as an anesthetic agent for intubation in patients with traumatic brain injury and mortality after 30 days in the prehospital setting, suggesting that the choice of induction agent may not influence the patient mortality rate in this population., (Copyright © 2024 The Author(s).

- Abstract
Objective: The aim of this systematic review was to compare extramedullary fixation and intramedullary fixation for AO type 31-A2 trochanteric fractures in the elderly, with regard to functional outcomes, complications, surgical outcomes, and costs., Methods: Embase, Medline, Web of Science, Cochrane Central Register of Controlled Trials, and Google Scholar were searched for randomized controlled trials (RCTs) and observational studies. Effect estimates were pooled across studies using random effects models. Results are presented as weighted risk ratio (RR) or weighted mean difference (MD) with corresponding 95% confidence interval (95% CI)., Results: Fourteen RCTs (2039 patients) and 13 observational studies (22,123 patients) were included. Statistically superior results in favor of intramedullary fixation were found for Harris Hip Score (MD 4.09, 95% CI 0.91-7.26, p = 0.04), Parker mobility score (MD - 0.67 95% CI - 1.2 to - 0.17, p = 0.009), lower extremity measure (MD - 4.07 95% CI - 7.4 to - 0.8, p = 0.02), time to full weight bearing (MD 1.14 weeks CI 0.92-1.35, p < 0.001), superficial infection (RR 2.06, 95% CI 1.18-3.58, p = 0.01), nonunion (RR 3.67, 95% CI 1.03-13.10, p = 0.05), fixation failure (RR 2.26, 95% CI 1.16-4.44, p = 0.02), leg shortening (MD 2.23 mm, 95% CI 0.81-3.65, p = 0.002), time to radiological bone healing (MD 2.19 months, 95% CI 0.56-3.83, p = 0.009), surgery duration (MD 11.63 min, 95% CI 2.63-20.62, p = 0.01), operative blood loss (MD 134.5 mL, 95% CI 51-218, p = 0.002), and tip-apex distance > 25 mm (RR 1.73, 95% CI 1.10-2.74, p = 0.02). No comparable cost/costs-effectiveness data were available., Conclusion: Current literature shows that several functional outcomes, complications, and surgical outcomes were statistically in favor of intramedullary fixation when compared with extramedullary fixation of AO/OTA 31-A2 fractures. However, as several of the differences found appear not to be clinically relevant and for many outcomes data remains sparse or heterogeneous, complete superiority of IM fixation for AO type 31-A2 fractures remains to be confirmed in a detailed cost-effectiveness analysis., (© 2023.

- Abstract
Background: Chest pain following a thoracotomy for esophageal cancer is frequently reported but poorly understood. This study aimed to (1) determine the prevalence of thoracotomy-related thoracic fractures on postoperative imaging and (2) compare complications, long-term pain, and quality of life in patients with versus without these fractures., Methods: This retrospective cohort study enrolled patients with esophageal cancer who underwent a thoracotomy between 2010 and 2020 with pre- and postoperative CTs (<1 and/or >6 months). Disease-free patients were invited for questionnaires on pain and quality of life., Results: Of a total of 366 patients, thoracotomy-related rib fractures were seen in 144 (39%) and thoracic transverse process fractures in 4 (2%) patients. Patients with thoracic fractures more often developed complications (89% vs. 74%, p = 0.002), especially pneumonia (51% vs. 39%, p = 0.032). Questionnaires were completed by 77 after a median of 41 (P
25 -P75 28-91) months. Long-term pain was frequently (63%) reported but was not associated with thoracic fractures (p = 0.637), and neither were quality of life scores., Conclusions: Thoracic fractures are prevalent in patients following a thoracotomy for esophageal cancer. These thoracic fractures were associated with an increased risk of postoperative complications, especially pneumonia, but an association with long-term pain or reduced quality of life was not confirmed., (© 2024 The Authors.

- Abstract
Purpose: This retrospective study aimed to validate the ACS NSQIP Surgical Risk Calculator (SCR) to predict 30-day postoperative outcomes in patients with one of the following subacute orthopedic trauma diagnoses; multiple rib fractures, pelvic ring/acetabular fracture, or unilateral femoral fracture., Methods: Data of patients with these diagnoses treated between January 1, 2015 and September 19, 2020 were extracted from the patients' medical files. Diagnostic performance, discrimination, calibration, and accuracy of the ACS NSQIP SRC to predict specific outcomes developing within 30 days after surgery was determined., Results: The total cohort of the three diagnoses consisted of 435 patients. ACS NSQIP SRC underestimated the risk for serious complications, especially in patients with multiple rib fractures (8.3% predicted vs 17.2% observed) or pelvic ring/acetabular fracture (6.1% vs 19.8%). Underestimation was more pronounced for the composite outcome 'any complication'. Sensitivity ranged from 16.7% to 100% and specificity from 41.1% to 97.1%. Specificity exceeded sensitivity for pelvic ring/acetabular and femoral fractures. Discrimination was good for predicting death (femoral fracture), fair for readmission (femoral fracture), serious complication (multiple rib fractures), and any complication (multiple rib fractures), but poor in all other outcomes and diagnoses. Calibration and accuracy were adequate for all three diagnoses (p-value for Hosmer-Lemeshow test >0.05 and Brier scores <0.25)., Conclusion: Performance of the ACS NSQIP SRC in the studied cohort was variable for all three diagnoses. Although it underestimated the risk of most outcomes, calibration and accuracy seemed generally adequate. For most outcomes, adequate diagnostic performance and discrimination could not be confirmed., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2024 The Authors.)

- Abstract
Introduction: Defining major trauma (MT) with an Injury Severity Score (ISS) > 15 has limitations. This threshold is used for concentrating MT care in networks with multiple levels of trauma care., Objective: This study aims to identify subgroups of severely injured patients benefiting on in-hospital mortality and non-fatal clinical outcome measures in an optimal level of trauma care., Methods: A multicentre retrospective cohort study on data of the Dutch National Trauma Registry, region South West, from January 1, 2015 until December 31, 2019 was conducted. Patients ≥ 16 years admitted within 48 h after trauma transported with (H)EMS to a level I trauma centre (TC) or a non-level I trauma facility with a Maximum Abbreviated Injury Scale (MAIS) ≥ 3 were included. Patients with burns or patients of ≥ 65 years with an isolated hip fracture were excluded. Logistic regression models were used for comparing level I with non-level I. Subgroup analysis were done for MT patients (ISS > 15) and non-MT patients (ISS 9-14)., Results: A total of 7,493 records were included. In-hospital mortality of patients admitted to a non-level I trauma facility did not differ significantly from patients admitted to the level I TC (adjusted Odds Ratio (OR): 0.94; 95% confidence interval (CI) 0.68-1.30). This was also applicable for MT patients (OR: 1.06; 95% CI 0.73-1.53) and non-MT patients (OR: 1.30; 95% CI (0.56-3.03). Hospital and ICU LOS were significantly shorter for patients admitted to a non-level I trauma facilities, and patients admitted to a non-level I trauma facility were more likely to be discharged home. Findings were confirmed for MT and non-MT patients, per injured body region., Conclusion: All levels of trauma care performed equally on in-hospital mortality among severely injured patients (MAIS ≥ 3), although patients admitted to the level I TC were more severely injured. Subgroups of patients by body region or ISS, with a survival benefit or more favorable clinical outcome measures were not identified. Subgroups analysis on clinical outcome measures across different levels of trauma care in an inclusive trauma network is too simplistic if subgroups are based on injuries in specific body region or ISS only., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 The Author(s).

- Abstract
Introduction: Quality improvement in prehospital emergency medical services (EMS) can only be achieved by high-quality research and critical appraisal of current practices. This study examines current opportunities and barriers in EMS research in the Netherlands., Methods: This mixed-methods consensus study consisted of three phases. The first phase consisted of semi-structured interviews with relevant stakeholders. Thematic analysis of qualitative data derived from these interviews was used to identify main themes, which were subsequently discussed in several online focus groups in the second phase. Output from these discussions was used to shape statements for an online Delphi consensus study among relevant stakeholders in EMS research. Consensus was met if 80% of respondents agreed or disagreed on a particular statement., Results: Forty-nine stakeholders participated in the study; qualitative thematic analysis of the interviews and focus group discussions identified four main themes: (1) data registration and data sharing, (2) laws and regulations, (3) financial aspects and funding, and (4) organization and culture. Qualitative data from the first two phases of the study were used to construct 33 statements for an online Delphi study. Consensus was reached on 21 (64%) statements. Eleven (52%) of these statements pertained to the storage and use of EMS patient data., Conclusion: Barriers for prehospital EMS research in the Netherlands include issues regarding the use of patient data, privacy and legislation, funding and research culture in EMS organizations. Opportunities to increase scientific productivity in EMS research include the development of a national strategy for EMS data and the incorporation of EMS topics in research agendas of national medical professional associations., (© 2023.

- Abstract
Background: Truncal and junctional hemorrhage is the leading cause of potentially preventable deaths in trauma patients. To reduce this mortality, the application of advanced bleeding control techniques, such as resuscitative endovascular balloon occlusion of the aorta (REBOA), junctional tourniquets, Foley catheters, or hemostatic agents should be optimized. This study aimed to identify trauma patients with non-compressible truncal and junctional hemorrhage (NCTJH) who might benefit from advanced bleeding control techniques during initial trauma care. We hypothesized that there is a substantial cohort of Dutch trauma patients that can possibly benefit from advanced bleeding control techniques., Methods: Adult trauma patients with an Abbreviated Injury Scale ≥3 in the torso, neck, axilla, or groin region, who were presented between January 1st, 2014 and December 31st, 2018 to two Dutch level-1 trauma centers, were identified from the Dutch Trauma Registry. Potential indications for advanced bleeding control in patients with NCTJH were assessed by an expert panel of three trauma surgeons based on injury characteristics, vital signs, response to resuscitation, and received treatment., Results: In total, 1719 patients were identified of whom 249 (14.5 %) suffered from NCTJH. In 153 patients (60.6 %), hemorrhagic shock could have been mitigated or prevented with advanced bleeding control techniques. This group was younger and more heavily injured: median age of 40 versus 48 years and median ISS 33 versus 22 as compared to the entire cohort. The mortality rate in these patients was 31.8 %. On average, each of the included level-1 trauma centers treated an NCTJH patient every 24 days in whom a form of advanced bleeding control could have been beneficial., Conclusions: More than half of included Dutch trauma patients with NCTJH may benefit from in-hospital application of advanced bleeding control techniques, such as REBOA, during initial trauma care. Widespread implementation of these techniques in the Dutch trauma system may contribute to reduction of mortality and morbidity from non-compressible truncal and junctional hemorrhage., Competing Interests: Declaration of Competing Interest The authors declare that there are no conflicts of interest that could inappropriately influence (bias) their work. We confirm that this submission has not been published elsewhere and is not under consideration by another journal. All authors have made substantial contributions to all of the following: (1) the conception and design of the study, or acquisition of data, or analysis and interpretation of data, (2) drafting the article or revising it critically for important intellectual content, (3) final approval of the version to be submitted., (Copyright © 2023 The Author(s).

- Abstract
Introduction: Population-based knowledge on the occurrence of femoral shaft fractures is necessary for allocation of health care services, optimization of preventive measures, and research purposes. This nationwide study aimed to provide an overview on the incidence of femoral shaft fractures over a 15-year period and to gain insight into health care consumption and work absence with associated costs in the Dutch population., Methods: Data of patients who sustained an acute femoral shaft fracture in the years 2005-2019 were extracted from the National Medical Registration of the Dutch Hospital Database. The incidence rate, hospital length of stay (HLOS), direct medical costs, productivity costs, and years lived with disability were calculated for age- and gender specific groups., Results: A total of 15,847 patients with a femoral shaft fracture were included. The incidence rate increased with 13 % over this 15-year period (5.71/100,000 persons per year in 2005 and 6.47/100,000 in 2019). The mean HLOS per patient was 13.8 days in 2005-2009 versus 8.4 days in 2015-2019 for the entire group. Mean HLOS per patient increased with age (10.0 days for age group 0-9 and 12.7 days for age group >80), but declined over time from 13.6 days in 2005-2009 to 8.8 days in 2015-2019 in males, and from 13.7 days and to 8.2 days, respectively, in females. The costs due to work absence was higher in males. Cumulative health care costs were highest in females >80 years (8.4 million euros versus 1.6 million in males)., Conclusion: The incidence rate of femoral shaft fractures increased over the past 15 years in the Netherlands. Mean HLOS per patient has decreased in all age groups and in both sexes. Health care costs were highest for female octogenarians., Competing Interests: Declaration of Competing Interest All authors declare that they have no conflict of interests or any competing interests., (Copyright © 2023 The Author(s).

- Abstract
The objective of this study was to determine whether there is an association between sex and outcome in trauma patients presented with severe traumatic brain injury (TBI). A retrospective multicenter study was performed in trauma patients aged ≥ 16 years who presented with severe TBI (Head Abbreviated Injury Scale (AIS) ≥ 4) over a 4-year-period. Subgroup analyses were performed for ages 16-44 and ≥45 years. Also, patients with isolated severe TBI (other AIS ≤ 2) were assessed, likewise, with subgroup analysis for age. Sex differences in mortality, Glasgow Outcome Score (GOS), ICU admission/length of stay (LOS), hospital LOS, and mechanical ventilation (MV) were examined. A total of 1566 severe TBI patients were included (831 patients with isolated TBI). Crude analysis shows an association between female sex and lower ICU admission rates, shorter ICU/hospital LOS, and less frequent and shorter MV in severe TBI patients ≥ 45 years. After adjusting, female sex appears to be associated with shorter ICU/hospital LOS. Sex differences in mortality and GOS were not found. In conclusion, this study found sex differences in patient outcomes following severe TBI, potentially favoring (older) females, which appear to indicate shorter ICU/hospital LOS (adjusted analysis). Large prospective studies are warranted to help unravel sex differences in outcomes after severe TBI.

- Abstract
Background and Purpose: Little is known about the activities of daily living (ADL) of patients with a bone-anchored prosthesis (BAP). We aimed to objectively measure ADL without and with BAP during standard care of follow-up. Our secondary aim was to measure mobility and walking ability., Patients and Methods: Patients aged 18-99 years who underwent surgery for transfemoral or transtibial BAP between September 11, 2017, and February 11, 2021, were eligible for inclusion in this retrospective case series of patients with socket prosthesis. ADL was measured with a continuous recording activity monitor (hours [h]) before surgery, and at 6, 12, and 24 months with BAP. Mobility and walking ability were assessed by the Timed Up and Go test (TUG) (seconds [s]) and 6 Minute Walk Test (6MWT) (meters [m]), respectively., Results: 48 of the 57 eligible patients provided informed consent and were included. Their age was 59 (1st quartile to 3rd quartile 51-63) years. Total daily activity before BAP was 1.6 h (0.82-2.1) and increased to 2.1 h (1.4-2.5) at 6, 2.0 h (1.5-2.7) at 12, and 2.7 h (2.0-3.3) at 24 months with BAP. Daily walking increased from 1.3 h (0.79-1.9) before BAP to 1.8 h (1.6-2.3) at 6, to 1.7 h (1.2-2.4) at 12, and 2.0 h (1.6-2.6) at 24 months. Median TUG decreased from 12 s (9.1-14) before BAP to 8.9 s (7.7-10) at 24 months. Mean 6MWT increased from 272 m (SD 92) before BAP to 348 m (SD 68) at 24 months., Conclusion: Objective measurements on ADL positively changed in patients with BAP. This effect was also seen in mobility and walking ability at 24 months.

- Abstract
Introduction: Fractures of the proximal femur accompanied by a fracture of the femoral shaft are relatively rare, with a reported prevalence between 1 and 12%. Multiple surgical options are available, consisting of treatment with a single implant or with double implants. Controversy exists about the optimal management. A systematic review and pooled analysis were performed to assess the most reliable treatment for bifocal femoral fractures of the femur., Materials and Methods: A literature search was conducted on July 15, 2022. Selected studies were screened on title and abstract by two researchers independently, and full texts were read by both authors. Emphasis was put on adverse events such as postoperative infection, healing complications, malalignment, and functional outcome using either a single implant or double implants., Results: For the proximal femoral fractures, no significant difference could be confirmed for avascular necrosis of the femoral neck (5.1% for single implant and 3.8% for double implants), nonunion (6.4% for single implant and 7.8% for double implants), or varus malalignment (6.6% for single implant and 10.9% for double implants). This study also suggests that the number of implants is irrelevant for complications of the femoral shaft regarding the rates of postoperative infection and healing complications. Pooled rates of bone healing complications were 1.6-2.7-fold higher when patients were treated with a single implant, but statistical significance could not be confirmed. For hardware failure, revision surgery, leg length discrepancy, and functional outcome, no difference between the two groups was found either., Conclusions: The pooled proportions of all postoperative complications had overlapping confidence intervals; thus, no inference about a statistically significant difference on the number of implants used for treating ipsilateral fractures of the femur can be made. Both treatment groups showed a similar functional outcome at the last moment of follow-up, with more than 75% of the patients reporting a good outcome., (© 2023. The Author(s).)

- Abstract
Aims: The aim of this study was to investigate the association between fracture displacement and survivorship of the native hip joint without conversion to a total hip arthroplasty (THA), and to determine predictors for conversion to THA in patients treated nonoperatively for acetabular fractures., Methods: A multicentre cross-sectional study was performed in 170 patients who were treated nonoperatively for an acetabular fracture in three level 1 trauma centres. Using the post-injury diagnostic CT scan, the maximum gap and step-off values in the weightbearing dome were digitally measured by two trauma surgeons. Native hip survival was reported using Kaplan-Meier curves. Predictors for conversion to THA were determined using Cox regression analysis., Results: Of 170 patients, 22 (13%) subsequently received a THA. Native hip survival in patients with a step-off ≤ 2 mm, > 2 to 4 mm, or > 4 mm differed at five-year follow-up (respectively: 94% vs 70% vs 74%). Native hip survival in patients with a gap ≤ 2 mm, > 2 to 4 mm, or > 4 mm differed at five-year follow-up (respectively: 100% vs 84% vs 78%). Step-off displacement > 2 mm (> 2 to 4 mm hazard ratio (HR) 4.9, > 4 mm HR 5.6) and age > 60 years (HR 2.9) were independent predictors for conversion to THA at follow-up., Conclusion: Patients with minimally displaced acetabular fractures who opt for nonoperative fracture treatment may be informed that fracture displacement (e.g. gap and step-off) up to 2 mm, as measured on CT images, results in limited risk on conversion to THA. Step-off ≥ 2 mm and age > 60 years are predictors for conversion to THA and can be helpful in the shared decision-making process., Competing Interests: All ICMJE Conflict of Interest forms for authors are on file with the publication and can be viewed on request.

- Abstract
Introduction: Humeral shaft fractures can be treated non-operatively or operatively. The optimal management is subject to debate. The aim was to compare non-operative and operative treatment of a humeral shaft fracture in terms of fracture healing, complications, and functional outcome., Methods: Databases of Embase, Medline ALL, Web-of-Science Core Collection, and the Cochrane Central Register of Controlled Trials (CENTRAL) were systematically searched for publications reporting clinical and functional outcomes of humeral shaft fractures after non-operative treatment with a functional brace or operative treatment by intramedullary nailing (IMN; antegrade or retrograde) or plate osteosynthesis (open plating or minimally invasive). A pooled analysis of the results was performed using MedCalc., Results: A total of 173 studies, describing 11,868 patients, were included. The fracture healing rate for the non-operative group was 89% (95% confidence interval (CI) 84-92%), 94% (95% CI 92-95%) for the IMN group and 96% (95% CI 95-97%) for the plating group. The rate of secondary radial nerve palsies was 1% in patients treated non-operatively, 3% in the IMN, and 6% in the plating group. Intraoperative complications and implant failures occurred more frequently in the IMN group than in the plating group. The DASH score was the lowest (7/100; 95% CI 1-13) in the minimally invasive plate osteosynthesis group. The Constant-Murley and UCLA shoulder score were the highest [93/100 (95% CI 92-95) and 33/35 (95% CI 32-33), respectively] in the plating group., Conclusion: This study suggests that even though all treatment modalities result in satisfactory outcomes, operative treatment is associated with the most favorable results. Disregarding secondary radial nerve palsy, specifically plate osteosynthesis seems to result in the highest fracture healing rates, least complications, and best functional outcomes compared with the other treatment modalities., (© 2023.

- Abstract
This study evaluated the incidence rates and societal burden of hip fractures in The Netherlands. Although incidence in the elderly population is decreasing and hospital stay is at an all-time low, the burden of medical costs and crude numbers of proximal femoral fractures are still rising in our aging population., Purpose: The aim of this nationwide study was to provide an overview of the incidence rate and economic burden of acute femoral neck and trochanteric fractures in The Netherlands., Methods: Data of patients who sustained acute proximal femoral fractures in the period January 1, 2000, to December 31, 2019, were extracted from the National Medical Registration of the Dutch Hospital Database. The incidence rate, hospital length of stay (HLOS), health care and lost productivity costs, and years lived with disability (YLD) were calculated for age- and sex-specific groups., Results: A total of 357,073 patients were included. The overall incidence rate increased by 22% over the 20-year study period from 16.4 to 27.1/100,000 person-years (py). The age-specific incidence rate in elderly > 65 years decreased by 16% (from 649.1 to 547.6/100,000 py). The incidence rate in men aged > 90 has surpassed the incidence rate in women. HLOS decreased in all age groups, hip fracture subtypes, and sexes from a mean of 18.5 to 7.2 days. The mean health care costs, over the 2015-2019 period, were lower for men (€17,723) than for women (€23,351) and increased with age to €26,639 in women aged > 80. Annual cumulative costs reached €425M, of which 73% was spent on women., Conclusion: The total incidence of hip fractures in The Netherlands has increased by 22%. Although incidence in the elderly population is decreasing and HLOS is at an all-time low, the burden of medical costs and crude numbers of proximal femoral fractures are still rising in our aging population., (© 2023.

- Abstract
Introduction: Several studies have shown the additional benefit of point-of-care ultrasound (POCUS) by prehospital Emergency Medical Services (EMS). Since organization of EMS may vary significantly across countries, the value of POCUS likely depends on the prehospital system in which it is used. In order to be able to optimally implement POCUS and develop a tailored training curriculum, it is important to know how often POCUS is currently used, for which indications it is used, and how it affects decision making. The aims of this study were: (1) to determine the percentage of patients in whom POCUS was used by Dutch Helicopter Emergency Medical Services (HEMS) crews; (2) to determine how often POCUS findings led to changes in on-scene management; and (3) what these changes were., Methods: Patients who received prehospital care from December 1, 2020 through March 31, 2021 by a single HEMS crew were included in this prospective cohort study. Clinical data and specific data on POCUS examination, findings, and therapeutic consequences were collected and analyzed., Results: During the study period, on-scene HEMS care was provided to 612 patients, of which 211 (34.5%) patients underwent POCUS. Of these, 209 (34.2%) patients with a median age of 45 years were included. There were 131 (62.7%) trauma patients, and 70 (33.7%) of the included patients underwent cardiopulmonary resuscitation (CPR). The median reported time of POCUS examination was three (P
25 -P75 2-5) minutes. Median prolongation of on-scene time was zero (P25 -P75 0-1) minutes. In 85 (40.7%) patients, POCUS examination had therapeutic consequence: POCUS was found to impact treatment decisions in 34 (26.0%) trauma patients and 51 (65.4%) non-trauma patients. In patients with cardiac arrest, POCUS was most often used to aid decision making with regard to terminating or continuing resuscitation (28 patients; 13.4%)., Conclusion: During the study period, POCUS examination was used in 34.5% of all prehospital HEMS patients and had a therapeutic consequence in 40.7% of patients. In trauma patients, POCUS seems to be most effective for patient triage and evaluation of treatment effectiveness. Moreover, POCUS can be of significant value in patients undergoing CPR. A tailored HEMS POCUS training curriculum should include ultrasound techniques for trauma and cardiac arrest.- Published

- Abstract
Objective: This systematic review and meta-analysis compared extramedullary fixation and intramedullary fixation for stable two-part trochanteric femoral fractures (AO type 31-A1) with regards to functional outcomes, complications, and surgical outcomes., Methods: Embase, Medline, Web of Science, Cochrane Central Register of Controlled Trials, and Google Scholar were searched for randomized controlled trials (RCTs) and observational studies. Effect estimates were pooled across studies using random effects models. Results were presented as weighted risk ratio (RR) or weighted mean difference (MD) with corresponding 95% confidence interval (95% CI)., Results: Five RCTs (397 patients) and 14 observational studies (21,396 patients) were included. No significant differences in functional outcomes, complications, or surgical outcomes were found between extramedullary and intramedullary fixation devices, except for a difference in duration of surgery (MD 14.1 min, CI 5.76-22.33, p < 0.001) and intra-operative blood loss (MD 92.30 mL, CI 13.49-171.12, p = 0.02), favoring intramedullary fixation., Conclusion: Current literature shows no meaningful differences in complications, surgical, or functional outcomes between extramedullary and intramedullary fixation of stable two-part trochanteric femoral fractures. Both treatment options result in good outcomes. This study implicates that, costs should be taken into account when considering implants or comparing fixation methods in future research., (© 2023.

- Abstract
Background: Plate osteosynthesis (referred to throughout as plating) and intramedullary nailing (referred to throughout as nailing) are the most common operative strategies for humeral shaft fractures. However, it is undecided which treatment is more effective. This study aimed to compare functional and clinical outcomes of these treatment strategies. We hypothesized that plating would result in an earlier recovery of shoulder function and fewer complications., Methods: From October 23, 2012, to October 3, 2018, adults with a humeral shaft fracture, OTA/AO type 12A or 12B, were enrolled in a multicenter, prospective cohort study. Patients were treated with plating or nailing. Outcome measures included the Disabilities of the Arm, Shoulder and Hand (DASH) score, Constant-Murley score, ranges of motion of the shoulder and elbow, radiographic healing, and complications until 1 year. Repeated-measure analysis was done with correction for age, sex, and fracture type., Results: Of the 245 included patients, 76 were treated with plating and 169 were treated with nailing. Patients in the plating group were younger, with a median age of 43 years compared with 57 years for the nailing group (p < 0.001). The mean DASH score after plating improved faster over time, but did not differ significantly from the score after nailing at 12 months (11.7 points [95% confidence interval (CI), 7.6 to 15.7 points]) for plating and 11.2 points [95% CI, 8.3 to 14.0 points] for nailing). The Constant-Murley score and shoulder abduction, flexion, external rotation, and internal rotation displayed a significant treatment effect (p treatment ≤ 0.001), in favor of plating. The plating group had 2 implant-related complications, whereas the nailing group had 24, including 13 nail protrusions and 8 screw protrusions. Plating resulted in more postoperative temporary radial nerve palsy (8 patients [10.5%] compared with 1 patient [0.6%]; p < 0.001) and a trend toward fewer nonunions (3 patients [5.7%] compared with 16 patients [11.9%]; p = 0.285) than nailing., Conclusions: Plating of a humeral shaft fracture in adults results in faster recovery, especially of shoulder function. Plating was associated with more temporary nerve palsies, but fewer implant-related complications and surgical reinterventions, than nailing. Despite heterogeneity in implants and surgical approach, plating seems to be the preferred treatment option for these fractures., Level of Evidence: Therapeutic Level II .

- Abstract
Background: Surgical stabilization of rib fractures (SSRF) is associated with improved respiratory symptoms and shorter intensive care admission in patients with flail chest. For multiple rib fractures, the benefit of SSRF remains a topic of debate. This study investigated barriers and facilitators of healthcare professionals to SSRF as treatment for multiple traumatic rib fractures., Methods: Dutch healthcare professionals were asked to complete an adapted version of the Measurement Instrument for Determinants of Innovations questionnaire to identify barriers and facilitators of SSRF. If ≥ 20% of participants responded negatively, the item was considered a barrier, and if ≥ 80% responded positively, the item was considered a facilitator., Results: Sixty-one healthcare professionals participated; 32 surgeons, 19 non-surgical physicians, and 10 residents. The median experience was 10 years (P
25 -P75 4-12). Sixteen barriers and two facilitators for SSRF in multiple rib fractures were identified. Barriers included lack of knowledge, experience, evidence on (cost-)effectiveness, and the implication of more operations and higher medical costs. Facilitators were the assumption that SSRF alleviates respiratory problems and the feeling that surgeons are supported by colleagues for SSRF. Non-surgeons and residents reported more and several different barriers than surgeons (surgeons: 14; non-surgical physicians: 20; residents: 21; p < 0.001)., Conclusion: For adequate implementation of SSRF in patients with multiple rib fractures, implementation strategies should address the identified barriers. Especially, improved clinical experience and scientific knowledge of healthcare professionals, and high-level evidence on the (cost-) effectiveness of SSRF potentially increase its use and acceptance., (© 2023.

- Abstract
Background: Trauma networks have multiple designated levels of trauma care. This classification parallels concentration of major trauma care, creating innovations and improving outcome measures., Objectives: The objective of this study is to assess associations of level of trauma care with patient outcomes for populations with specific severe injuries., Methods: A systematic literature search was conducted using six electronic databases up to April 19, 2022 (PROSPERO CRD42022327576). Studies comparing fatal, nonfatal clinical, or functional outcomes across different levels of trauma care for trauma populations with specific severe injuries or injured body region (Abbreviated Injury Scale score ≥3) were included. Two independent reviewers included studies, extracted data, and assessed quality. Unadjusted and adjusted pooled effect sizes were calculated with random-effects meta-analysis comparing Level I and Level II trauma centers., Results: Thirty-five studies (1,100,888 patients) were included, of which 25 studies (n = 443,095) used for meta-analysis, suggesting a survival benefit for the severely injured admitted to a Level I trauma center compared with a Level II trauma center (adjusted odds ratio [OR], 1.15; 95% confidence interval [CI], 1.06-1.25). Adjusted subgroup analysis on in-hospital mortality was done for patients with traumatic brain injuries (OR, 1.23; 95% CI, 1.01-1.50) and hemodynamically unstable patients (OR, 1.09; 95% CI, 0.98-1.22). Hospital and intensive care unit length of stay resulted in an unadjusted mean difference of -1.63 (95% CI, -2.89 to -0.36) and -0.21 (95% CI, -1.04 to 0.61), respectively, discharged home resulted in an unadjusted OR of 0.92 (95% CI, 0.78-1.09)., Conclusion: Severely injured patients admitted to a Level I trauma center have a survival benefit. Nonfatal outcomes were indicative for a longer stay, more intensive care, and more frequently posthospital recovery trajectories after being admitted to top levels of trauma care. Trauma networks with designated levels of trauma care are beneficial to the multidisciplinary character of trauma care., Level of Evidence: Systematic review and meta-analysis; Level III., (Copyright © 2023 The Author(s).

- Abstract
Purpose: Data on the epidemiology, treatment, and outcome of burn patients treated at non-burn centre hospitals are not available. The primary aim was to compare the burn characteristics of patients admitted to a hospital with or without a specialized burn centre., Methods: This multicentre, prospective, cohort study enrolled patients with burns admitted to a hospital without a burn centre and patients with < 10% total body surface area (TBSA) burned admitted to the burn centre. Primary outcome measure was the burn-related injury characteristics. Secondary outcome measures were adherence to the Emergency Management of Severe Burns (EMSB) referral criteria, treatment (costs), quality of life, and scar quality., Results: During the 2-year study period, 48 patients were admitted to a non-burn centre and 148 patients to the burn centre. In the non-burn centre group, age [44 (P
25 -P75 26-61) versus 30 (P25 -P75 8-52) years; P = 0.007] and Injury Severity Score [2 (P25 -P75 1-4) versus 1 (P25 -P75 1-1); P < 0.001] were higher. In the burn centre group, the TBSA burned was significantly higher [4% (P25 -P75 2-6) versus 2% (P25 -P75 1-4); P = 0.001], and more surgical procedures were performed (in 54 versus 7 patients; P = 0.004). At 12 months, > 85% of the non-burn centre group and > 75% of the burn centre group reported no problems in quality of life. Scar quality score was < 1.5 in both groups, with significantly poorer scores in the burn centre group (P ≤ 0.007)., Conclusion: Both groups differed in patient, burn, and treatment characteristics. At 12 months, quality of life and scar quality were good in both groups. Significantly poorer scar quality scores were found in the burn centre group. This might be related to their larger burns and more frequent surgery. The organization of burn care in the Netherlands seems to work adequately. Patients are treated locally when possible and are transferred when necessary., (© 2023. The Author(s).)- Published
