Increasingly, physicians rely on computerized tomography (CT) to aid in the workup of acute appendicitis (AA) in children despite the potential negative effects of CT-associated radiation exposure. Few studies have investigated the context or location in which the decision to perform CT for AA is made. We sought to determine where the decision to use CT was made during the initial workup of pediatric patients who later underwent an appendectomy. We reviewed the medical record of all patients at a children's hospital (CH) receiving appendectomy over 10.5 years. We abstracted clinical variables using an established clinical AA scoring system, demographics and outcome variables. Patients who underwent CT were compared with those who did not. Additionally, we identified the location where the CT was performed. Our children's hospital was compared with referring hospitals (RHs) with regard to utilization of CT imaging. Five hundred and forty-six patients underwent appendectomy for AA at CH. Of these, 50 per cent underwent CT. Patients who initially presented at the RHs underwent CT at a significantly higher rate than those first presenting to CH (P < 0.0001). Moreover, we found that unlike at the RHs, patients with a higher AA score underwent CT at CH less often (P < 0.0002). RHs used CT more often than CH to diagnose AA in our cohort. CH avoided CT for patients with higher Alvarado scores. Further research is needed to elucidate factors that lead healthcare providers to use CT for children with suspected AA to eliminate unnecessary CT-associated radiation exposure.

Objectives: The number of older adults struggling to maintain adequate housing is growing. Prior studies have used various criteria to measure housing insecurity; however, no standardized definition exists to date. Using a multidimensional approach, our study sought to calculate population-based estimates of various forms of housing insecurity among community-living older Americans and determine how these estimates differ across key characteristics., Methods: This study utilized data from the 2011 round of the National Health and Aging Trends Study (NHATS), a prospective longitudinal study of Medicare beneficiaries aged 65 years or older. Three key forms of housing insecurity were operationalized: poor housing affordability (PHA), poor housing quality (PHQ), and poor neighborhood quality (PNQ). Population-based estimates of these forms of housing insecurity were calculated using analytic sampling weights and stratified by age, gender, race and ethnicity, frailty status, and dementia status., Results: Totally 6466 participants were included in the analysis, representing 29,848,119 community-living older Americans. The mean (standard deviation) age was 77.3 (7.7) years; by weighted percentages, 56.0% identified as female, 81.3% as White, 8.2% Black, and 7.1% Hispanic. At least one form of housing insecurity was identified in 38.5% of older Americans. Individually, the prevalence of PHA was 14.8%, PHQ 24%, and PNQ 12.5%. The prevalence of at least one form of housing insecurity was higher among persons of color (62.9% Black and 66% Hispanic vs White; p < 0.001), those with frailty (40.9% pre-frail and 49.4% frail vs robust; p < 0.001), and those with cognitive impairment (48.1% possible and 51% probable dementia vs no dementia; p < 0.001)., Discussion: Nearly one in three community-living older Americans experience at least one form of housing insecurity. This was most common among vulnerable subgroups. Our multidimensional approach to defining various forms of housing insecurity can be used for future studies focused on improving social determinants of health among high-risk older adults., (© 2024 The American Geriatrics Society.)

Background: Among older persons, neighborhood disadvantage is a granular and increasingly used social determinant of health and functional well-being. The frequency of transitions into or out of a disadvantaged neighborhood over time is not known. These transitions may occur when a person moves from one location to another or when the Neighborhood Atlas, the data source for the area deprivation index (ADI) that is used to identify disadvantaged neighborhoods at the census-block level, is updated., Methods: From a prospective longitudinal study of community-living persons, aged 70 years or older in South Central Connecticut, neighborhood disadvantage was ascertained every 18 months for 22 years (from March 1998 to March 2020). ADI scores higher than the 80th state percentile were used to distinguish neighborhoods that were disadvantaged (81-100) from those that were not (1-80)., Results: At baseline, 205 (29.3%) of the 699 participants were living in a disadvantaged neighborhood. Changes in neighborhood disadvantage during 14 consecutive 18-month intervals were relatively uncommon, ranging from 1.5% to 11.8%. Nearly 80% of participants had no change in neighborhood disadvantage and less than 4% had more than one change over a median follow-up of more than 9 years. Overall, the rate of transitions into or out of neighborhood disadvantage was only 2.7 per 100 person-years. These transitions were most common when the Neighborhood Atlas was updated (2013, 2015, 2018, and 2020). Comparable results were observed when decile changes in ADI scores during the 18-month intervals were evaluated., Conclusions: In longitudinal studies of older persons with extended follow-up, it may not be necessary to update information on disadvantaged neighborhoods in circumstances when it is possible, and the degree of misclassification of neighborhood disadvantage should be relatively low in circumstances when updated information cannot be obtained., (© 2024 The American Geriatrics Society.)

Background: Cognitive decline may be an early indicator of major health issues in older adults, though research using population-based data is lacking. Researchers objective was to assess the relationships between distinct cognitive trajectories and subsequent health outcomes, including health status, depressive symptoms, and mortality, using a nationally representative cohort., Methods: Data were drawn from the National Health and Aging Trends Study. Global cognition was assessed annually between 2011 and 2018. The health status of 4 413 people, depressive symptoms in 4 342 individuals, and deaths among 5 955 living respondents were measured in 2019. Distinct cognitive trajectory groups were identified using an innovative Bayesian group-based trajectory model. Ordinal logistic, Poisson, and logistic regression models were used to examine the associations between cognitive trajectories and subsequent health outcomes., Results: Researchers identified five cognitive trajectory groups with distinct baseline values and subsequent changes in cognitive function. Compared with the group with stably high cognitive function, worse cognitive trajectories (ie, lower baseline values and sharper declines) were associated with higher risks of poor health status, depressive symptoms, and mortality, even after adjusting for relevant covariates., Conclusions: Among older adults, worse cognitive trajectories are strongly associated with subsequent poor health status, high depressive symptoms, and high mortality risks. Regular screening of cognitive function may help to facilitate early identification and interventions for older adults susceptible to adverse health outcomes., (© The Author(s) 2024.

Importance: While immunotherapy is being used in an expanding range of clinical scenarios, the incidence of immunotherapy initiation at the end of life (EOL) is unknown., Objective: To describe patient characteristics, practice patterns, and risk factors concerning EOL-initiated (EOL-I) immunotherapy over time., Design, Setting, and Participants: Retrospective cohort study using a US national clinical database of patients with metastatic melanoma, non-small cell lung cancer (NSCLC), or kidney cell carcinoma (KCC) diagnosed after US Food and Drug Administration approval of immune checkpoint inhibitors for the treatment of each disease through December 2019. Mean follow-up was 13.7 months. Data analysis was performed from December 2022 to May 2023., Exposures: Age, sex, race and ethnicity, insurance, location, facility type, hospital volume, Charlson-Deyo Comorbidity Index, and location of metastases., Main Outcomes and Measures: Main outcomes were EOL-I immunotherapy, defined as immunotherapy initiated within 1 month of death, and characteristics of the cohort receiving EOL-I immunotherapy and factors associated with its use., Results: Overall, data for 242 371 patients were analyzed. The study included 20 415 patients with stage IV melanoma, 197 331 patients with stage IV NSCLC, and 24 625 patients with stage IV KCC. Mean (SD) age was 67.9 (11.4) years, 42.5% were older than 70 years, 56.0% were male, and 29.3% received immunotherapy. The percentage of patients who received EOL-I immunotherapy increased over time for all cancers. More than 1 in 14 immunotherapy treatments in 2019 were initiated within 1 month of death. Risk-adjusted patients with 3 or more organs involved in metastatic disease were 3.8-fold more likely (95% CI, 3.1-4.7; P < .001) to die within 1 month of immunotherapy initiation than those with lymph node involvement only. Treatment at an academic or high-volume center rather than a nonacademic or very low-volume center was associated with a 31% (odds ratio, 0.69; 95% CI, 0.65-0.74; P < .001) and 30% (odds ratio, 0.70; 95% CI, 0.65-0.76; P < .001) decrease in odds of death within a month of initiating immunotherapy, respectively., Conclusions and Relevance: Findings of this cohort study show that the initiation of immunotherapy at the EOL is increasing over time. Patients with higher metastatic burden and who were treated at nonacademic or low-volume facilities had higher odds of receiving EOL-I immunotherapy. Tracking EOL-I immunotherapy can offer insights into national prescribing patterns and serve as a harbinger for shifts in the clinical approach to patients with advanced cancer.

Importance: Nationally representative estimates of hospital readmissions within 30 and 180 days after major surgery, including both fee-for-service and Medicare Advantage beneficiaries, are lacking., Objectives: To provide population-based estimates of hospital readmission within 30 and 180 days after major surgery in community-living older US residents and examine whether these estimates differ according to key demographic, surgical, and geriatric characteristics., Design, Setting, and Participants: A prospective longitudinal cohort study of National Health and Aging Trends Study data (calendar years 2011-2018), linked to records from the Centers for Medicare & Medicaid Services (CMS). Data analysis was conducted from April to August 2023. Participants included community-living US residents of the contiguous US aged 65 years or older who had at least 1 major surgery from 2011 to 2018. Data analysis was conducted from April 10 to August 28, 2023., Main Outcomes and Measures: Major operations and hospital readmissions within 30 and 180 days were identified through data linkages with CMS files that included both fee-for-service and Medicare Advantage beneficiaries. Data on frailty and dementia were obtained from the annual National Health and Aging Trends Study assessments., Results: A total of 1780 major operations (representing 9 556 171 survey-weighted operations nationally) were identified from 1477 community-living participants; mean (SD) age was 79.5 (7.0) years, with 56% being female. The weighted rates of hospital readmission were 11.6% (95% CI, 9.8%-13.6%) for 30 days and 27.6% (95% CI, 24.7%-30.7%) for 180 days. The highest readmission rates within 180 days were observed among participants aged 90 years or older (36.8%; 95% CI, 28.3%-46.3%), those undergoing vascular surgery (45.8%; 95% CI, 37.7%-54.1%), and persons with frailty (36.9%; 95% CI, 30.8%-43.5%) or probable dementia (39.0%; 95% CI, 30.7%-48.1%). In age- and sex-adjusted models with death as a competing risk, the hazard ratios for hospital readmission within 180 days were 2.29 (95% CI, 1.70-3.09) for frailty and 1.58 (95% CI, 1.15-2.18) for probable dementia., Conclusions and Relevance: In this nationally representative cohort study of community-living older US residents, the likelihood of hospital readmissions within 180 days after major surgery was increased among older persons who were frail or had probable dementia, highlighting the potential value of these geriatric conditions in identifying those at increased risk.

Objectives: To evaluate the relationship between distressing symptoms and changes in disability after major surgery and to determine whether this relationship differs according to the timing of surgery (nonelective vs elective), sex, multimorbidity, and socioeconomic disadvantage., Background: Major surgery is a common and serious health event that has pronounced deleterious effects on both distressing symptoms and functional outcomes in older persons., Methods: From a cohort of 754 community-living persons, aged 70 or older, 392 admissions for major surgery were identified from 283 participants who were discharged from the hospital. The occurrence of 15 distressing symptoms and disability in 13 activities were assessed monthly for up to 6 months after major surgery., Results: Over the 6-month follow-up period, each unit increase in the number of distressing symptoms was associated with a 6.4% increase in the number of disabilities [adjusted rate ratio (RR): 1.064; 95% CI: 1.053, 1.074]. The corresponding increases were 4.0% (adjusted RR: 1.040; 95% CI: 1.030, 1.050) and 8.3% (adjusted RR: 1.083; 95% CI: 1.066, 1.101) for nonelective and elective surgeries. Based on exposure to multiple (ie, 2 or more) distressing symptoms, the adjusted RRs (95% CI) were 1.43 (1.35, 1.50), 1.24 (1.17, 1.31), and 1.61 (1.48, 1.75) for all, nonelective, and elective surgeries. Statistically significant associations were observed for each of the other subgroups with the exception of individual-level socioeconomic disadvantage for the number of distressing symptoms., Conclusions: Distressing symptoms are independently associated with worsening disability, providing a potential target for improving functional outcomes after major surgery., Competing Interests: The authors report no conflicts of interest., (Copyright © 2023 Wolters Kluwer Health, Inc.

Purpose: Studies on inguinal hernia repair in patients with ascites are limited, small, and inconsistent, exacerbating a challenging clinical dilemma for surgeons. To fill this gap in the literature, this retrospective cohort study used a national US database to examine the impact of ascites on the outcomes of open inguinal herniorrhaphy., Methods: Patients who underwent open inguinal herniorrhaphy between 2005 and 2019 were identified in the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database. Two groups were defined by the presence or absence of nonmalignant preoperative ascites. Ascites patients were propensity matched 1:10 with non-ascites patients. Surgical outcomes at 30 days for the matched groups, stratified by electiveness of procedure, were compared, with the primary end points of mortality and the NSQIP composite outcome "serious complication"., Results: The study included 682 patients with ascites. Compared to matched controls, those with ascites had significantly increased odds of mortality (OR 3.3, 95% CI 1.5-7.0) after elective repair, but not after nonelective repair. Ascites was associated with increased odds of serious complication after both elective (OR 1.7, 1.2-2.3) and nonelective (OR 2.0, 1.3-3.0) surgery. Among ascites patients, age ≥ 65 years was associated with increased mortality (risk-adjusted OR 3.8, 1.2-14.4) and serious complication (OR 2.2, 1.2-3.9)., Conclusion: In this largest study to date on patients with ascites undergoing open inguinal herniorrhaphy, ascites increased the odds of mortality after elective repair and of serious complication after elective and nonelective repair. Age ≥ 65 was a risk factor for poor outcome. Inguinal herniorrhaphy is fraught with complications in this population., (© 2023.

Background: Relatively little is known about how distressing symptoms change among older persons in the setting of major surgery. Our objective was to evaluate changes in distressing symptoms after major surgery and determine whether these changes differ according to the timing of surgery (nonelective vs. elective), sex, multimorbidity, and socioeconomic disadvantage., Methods: From a prospective longitudinal study of 754 nondisabled community-living persons, 70 years of age or older, 368 admissions for major surgery were identified from 274 participants who were discharged from the hospital from March 1998 to December 2017. The occurrence of 15 distressing symptoms was ascertained in the month before and 6 months after major surgery. Multimorbidity was defined as more than two chronic conditions. Socioeconomic disadvantage was assessed at the individual level, based on Medicaid eligibility, and neighborhood level, based on an area deprivation index (ADI) score above the 80th state percentile., Results: In the month before major surgery, the occurrence and mean number of distressing symptoms were 19.6% and 0.75, respectively. In multivariable analyses, the rate ratios, denoting proportional increases in the 6 months after major surgery relative to presurgery values, were 2.56 (95% confidence interval [CI], 1.91-3.44) and 2.90 (95% CI, 2.01-4.18) for the occurrence and number of distressing symptoms, respectively. The corresponding values were 3.54 (95% CI, 2.06-6.08) and 4.51 for nonelective surgery (95% CI, 2.32-8.76) and 2.12 (95% CI, 1.53-2.92) and 2.20 (95% CI, 1.48-3.29) for elective surgery; p-values for interaction were 0.030 and 0.009. None of the other subgroup differences were statistically significant, although men had a greater proportional increase in the occurrence and number of distressing symptoms than women., Conclusions: Among community-living older persons, the burden of distressing symptoms increases substantially after major surgery, especially in those having nonelective procedures. Reducing symptom burden has the potential to improve quality of life and enhance functional outcomes after major surgery., (© 2023 The American Geriatrics Society.)

Objective: To identify the factors associated with days away from home in the year after hospital discharge for major surgery., Background: Relatively little is known about which older persons are susceptible to spending a disproportionate amount of time in hospitals and other health care facilities after major surgery., Methods: From a cohort of 754 community-living persons, aged 70+ years, 394 admissions for major surgery were identified from 289 participants who were discharged from the hospital. Candidate risk factors were assessed every 18 months. Days away from home were calculated as the number of days spent in a health care facility., Results: In the year after major surgery, the mean (SD) and median (interquartile range) number of days away from home were 52.0 (92.2) and 15 (0-51). In multivariable analysis, 5 factors were independently associated with the number of days away from home: age 85 years and older, low score on the Short Physical Performance Battery, low peak expiratory flow, low functional self-efficacy, and musculoskeletal surgery. Based on the presence versus absence of these factors, the absolute mean differences in the number of days away from home ranged from 31.2 for age 85 years and older to 53.5 for low functional self-efficacy., Conclusions: The 5 independent risk factors can be used to identify older persons who are particularly susceptible to spending a disproportionate amount of time away from home after major surgery, and a subset of these factors can also serve as targets for interventions to improve quality of life by reducing time spent in hospitals and other health care facilities., Competing Interests: The authors report no conflicts of interest., (Copyright © 2022 Wolters Kluwer Health, Inc.

Background: This study aims to quantitatively assess use of the NSQIP surgical risk calculator (NSRC) in contemporary surgical practice and to identify barriers to use and potential interventions that might increase use., Materials and Methods: We performed a cross-sectional study of surgeons at seven institutions. The primary outcomes were self-reported application of the calculator in general clinical practice and specific clinical scenarios as well as reported barriers to use., Results: In our sample of 99 surgeons (49.7% response rate), 73.7% reported use of the NSRC in the past month. Approximately half (51.9%) of respondents reported infrequent NSRC use (<20% of preoperative discussions), while 14.3% used it in ≥40% of preoperative assessments. Reported use was higher in nonelective cases (30.2% vs 11.1%) and in patients who were ≥65 years old (37.1% vs 13.0%), functionally dependent (41.2% vs 6.6%), or with surrogate consent (39.9% vs 20.4%). NSRC use was not associated with training status or years in practice. Respondents identified a lack of influence on the decision to pursue surgery as well as concerns regarding the calculator's accuracy as barriers to use. Surgeons suggested improving integration to workflow and better education as strategies to increase NSRC use., Conclusions: Many surgeons reported use of the NSRC, but few used it frequently. Surgeons reported more frequent use in nonelective cases and frail patients, suggesting the calculator is of greater utility for high-risk patients. Surgeons raised concerns about perceived accuracy and suggested additional education as well as integration of the calculator into the electronic health record., Competing Interests: Disclosures/Conflicts of interest Neither this group nor its members have any disclosures or conflicts of interest to disclose.

Background: Initiation of oncologic care is often delayed, yet little is known about delays in hepatopancreatobiliary (HPB) cancers or their impact. This retrospective cohort study describes trends in time to treatment initiation (TTI), assesses the association between TTI and survival, and identifies predictors of TTI in HPB cancers., Methods: The National Cancer Database was queried for patients with cancers of the pancreas, liver, and bile ducts between 2004 and 2017. Kaplan-Meier survival analysis and Cox regression were used to investigate the association between TTI and overall survival for each cancer type and stage. Multivariable regression identified factors associated with longer TTI., Results: Of 318,931 patients with HPB cancers, median TTI was 31 days. Longer TTI was associated with increased mortality in patients with stages I-III extrahepatic bile duct (EHBD) cancer and stages I-II pancreatic adenocarcinoma. Patients treated within 3-30, 31-60, and 61-90 days had median survivals of 51.5, 34.9, and 25.4 months (log-rank P<0.001), respectively, for stage I EHBD cancer, and 18.8, 16.6, and 15.2 months for stage I pancreatic cancer, respectively (P<0.001). Factors associated with increased TTI included stage I disease (+13.7 days vs. stage IV, P<0.001), treatment with radiation only (β=+13.9 days, P<0.001), Black race (+4.6 days, P<0.001) and Hispanic ethnicity (+4.3 days, P<0.001)., Conclusions: Some HPB cancer patients with longer time to definitive care experienced higher mortality than patients treated expeditiously, particularly in non-metastatic EHBD cancer. Black and Hispanic patients are at risk for delayed treatment.

Introduction: Natural disasters may lead to increases in community violence due to broad social disruption, economic hardship, and large-scale morbidity and mortality. The effect of the COVID-19 pandemic on community violence is unknown., Methods: Using trauma registry data on all violence-related patient presentations in Connecticut from 2018 to 2021, we compared the pattern of violence-related trauma from pre-COVID and COVID pandemic using an interrupted time series linear regression model., Results: There was a 55% increase in violence-related trauma in the COVID period compared with the pre-COVID period (IRR: 1.55; 95%CI: 1.34-1.80; p-value<0.001) driven largely by penetrating injuries. This increase disproportionately impacted Black/Latinx communities (IRR: 1.61; 95%CI: 1.36-1.90; p-value<0.001)., Conclusion: Violence-related trauma increased during the COVID-19 pandemic. Increased community violence is a significant and underappreciated negative health and social consequence of the COVID-19 pandemic, and one that excessively burdens communities already at increased risk from systemic health and social inequities., Competing Interests: Declaration of competing interest All authors have no conflicts of interest to disclose., (Copyright © 2022 Elsevier Inc.

Objective: To identify the rates and possible predictors of alcohol withdrawal syndrome (AWS) among adult trauma patients., Methods: This is a retrospective review of all adult patients (18 years or older) included in the 2017 and 2018 American College of Surgeons Trauma Quality Program Participant User File (PUF). The main outcomes were rates and predictors of AWS., Results: 1 677 351 adult patients were included in the analysis. AWS was reported in 11 056 (0.7%). The rate increased to 0.9% in patients admitted for more than 2 days and 1.1% in those admitted for more than 3 days. Patients with AWS were more likely to be male (82.7% vs. 60.7%, p<0.001), have a history of alcohol use disorder (AUD) (70.3% vs. 5.6%, p<0.001) and have a positive blood alcohol concentration (BAC) on admission (68.2% vs. 28.6%, p<0.001). In a multivariable logistic regression, history of AUD (OR 12.9, 95% CI 12.1 to 13.7), cirrhosis (OR 2.1, 95% CI 1.9 to 2.3), positive toxicology screen for barbiturates (OR 2.1, 95% CI 1.6 to 2.7), tricyclic antidepressants (OR 2.2, 95% CI 1.5 to 3.1) or alcohol (OR 2.5, 95% CI 2.4 to 2.7), and Abbreviated Injury Scale head score of ≥3 (OR 1.7, 95% CI 1.6 to 1.8) were the strongest predictors for AWS. Conversely, only 2.7% of patients with a positive BAC on admission, 7.6% with a history of AUD and 4.9% with cirrhosis developed AWS., Conclusion: AWS after trauma was an uncommon occurrence in the patients in the PUF, even in higher-risk patient populations., Level of Evidence: IV: retrospective study with more than one negative criterion., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Objective: The objective of this study was to estimate the incidence and cumulative risk of major surgery in older persons over a 5-year period and evaluate how these estimates differ according to key demographic and geriatric characteristics., Background: As the population of the United States ages, there is considerable interest in ensuring safe, high-quality surgical care for older persons. Yet, valid, generalizable data on the occurrence of major surgery in the geriatric population are sparse., Methods: We evaluated data from a prospective longitudinal study of 5571 community-living fee-for-service Medicare beneficiaries, aged 65 or older, from the National Health and Aging Trends Study from 2011 to 2016. Major surgeries were identified through linkages with Centers for Medicare and Medicaid Services data. Population-based incidence and cumulative risk estimates incorporated National Health and Aging Trends Study analytic sampling weights and cluster and strata variables., Results: The nationally representative incidence of major surgery per 100 person-years was 8.8, with estimates of 5.2 and 3.7 for elective and nonelec-tive surgeries. The adjusted incidence of major surgery peaked at 10.8 in persons 75 to 79 years, increased from 6.6 in the non-frail group to 10.3 in the frail group, and was similar by sex and dementia. The 5-year cumulative risk of major surgery was 13.8%, representing nearly 5 million unique older persons, including 12.1% in persons 85 to 89 years, 9.1% in those ≥90 years, 12.1% in those with frailty, and 12.4% in those with probable dementia., Conclusions: Major surgery is a common event in the lives of community-living older persons, including high-risk vulnerable subgroups., Competing Interests: The authors report no conflicts of interest., (Copyright © 2021 Wolters Kluwer Health, Inc.

Importance: Despite their importance to guiding public health decision-making and policies and to establishing programs aimed at improving surgical care, contemporary nationally representative mortality data for geriatric surgery are lacking., Objective: To calculate population-based estimates of mortality after major surgery in community-living older US adults and to determine how these estimates differ according to key demographic, surgical, and geriatric characteristics., Design, Setting, and Participants: Prospective longitudinal cohort study with 1 year of follow-up in the continental US from 2011 to 2018. Participants included 5590 community-living fee-for-service Medicare beneficiaries, aged 65 years or older, from the National Health and Aging Trends Study (NHATS). Data analysis was conducted from February 22, 2021, to March 16, 2022., Main Outcomes and Measures: Major surgeries and mortality over 1 year were identified through linkages with data from the Centers for Medicare & Medicaid Services. Data on frailty and dementia were obtained from the annual NHATS assessments., Results: From 2011 to 2017, of the 1193 major surgeries (from 992 community-living participants), the mean (SD) age was 79.2 (7.1) years; 665 were women (55.7%), and 30 were Hispanic (2.5%), 198 non-Hispanic Black (16.6%), and 915 non-Hispanic White (76.7%). Over the 1-year follow-up period, there were 206 deaths representing 872 096 survey-weighted deaths and 13.4% (95% CI, 10.9%-15.9%) mortality. Mortality rates were 7.4% (95% CI, 4.9%-9.9%) for elective surgeries and 22.3% (95% CI, 17.4%-27.1%) for nonelective surgeries. For geriatric subgroups, 1-year mortality was 6.0% (95% CI, 2.6%-9.4%) for persons who were nonfrail, 27.8% (95% CI, 21.2%-34.3%) for those who were frail, 11.6% (95% CI, 8.8%-14.4%) for persons without dementia, and 32.7% (95% CI, 24.3%-41.0%) for those with probable dementia. The age- and sex-adjusted hazard ratios for 1-year mortality were 4.41 (95% CI, 2.53-7.69) for frailty with a reduction in restricted mean survival time of 48.8 days and 2.18 (95% CI, 1.40-3.40) for probable dementia with a reduction in restricted mean survival time of 44.9 days., Conclusions and Relevance: In this study, the population-based estimate of 1-year mortality after major surgery among community-living older adults in the US was 13.4% but was 3-fold higher for nonelective than elective procedures. Mortality was considerably elevated among older persons who were frail or who had probable dementia, highlighting the potential prognostic value of geriatric conditions after major surgery.

Introduction: Geographic variation is an inherent feature of the US health system. Despite efforts to account for geographic variation in trauma system strengthening, it remains unclear how trauma "regions" should be defined. The objective of this study is to evaluate the utility of a novel definition of Trauma Referral Regions (TRR) for assessing geographic variation in inpatient trauma across the age span of hospitalized trauma patients., Methods: Using 2016-2017 State Inpatient Databases, we assessed the extent of geographic variability in three common metrics of hospital use (localization index, market share index, net patient flow) among TRRs and, as a comparison, trauma regions alternatively defined based on Hospital Referral Regions, Hospital Service Areas, and counties., Results: A total of 860,593 admissions from 102 TRRs, 127 Hospital Referral Regions, 884 Hospital Service Areas, and 583 counties were included. Consistent with expectations for distinct trauma regions, TRR presented with high average localization indices (mean [standard deviation]: 83.4 [11.7%]), low market share indices (mean [standard deviation]: 11.9 [7.0%]), and net patient flows close to 1.00. Similar results were found among stratified pediatric, adult, and older adult patients. Associations between TRRs and variations in important demographic features (e.g., travel time by road to the nearest Level I or II Trauma Center) suggest that while indicative of standalone trauma regions, TRRs are also able to simultaneously capture critical variations in regional trauma care., Conclusions: TRRs offer a standalone set of geographic regions with minimal variation in common metrics of hospital use, minimal geographic clustering, and preserved associations with important demographic factors. They provide a needed, valid means of assessing geographic variation among trauma systems., (Copyright © 2022 Elsevier Inc. All rights reserved.)

Background: The regional extent of the risk of repeat firearm-related injury (FRI) and homicide mortality for victims of firearm injury in Connecticut is unknown. In this study, we evaluate the risk of repeat firearm injury in survivors of firearm violence in Connecticut., Methods: Using medical record data from the Yale New Haven Health (YNHH) system and data from the Connecticut Office of the Chief Medical Examiner, we conducted a cohort study of patients with an FRI in 2014 to determine their risk of a repeat firearm injury or mortality from homicide in the ensuing 5 years compared with nonviolence-related trauma patient controls., Results: We identified 94 patients with an FRI in the YNHH system from 2014 who survived to discharge. Of these patients, 8.5% (8 of 94) had a repeat FRI and 2% (2 of 94) died from homicide within the next 5 years. Compared with nonviolence-related trauma patients from 2014 (n = 2001), those with an FRI had 12 times the odds of a repeat firearm injury (odds ratio: 12.0, P = 0.047) in the next 5 years after adjustment for relevant covariates., Conclusions: Of the patients presenting with an initial FRI in the YNHH system, one in twelve will experience another firearm injury within the next 5 years. These data indicate that firearm-related reinjury is common in Connecticut and suggest the need for further violence prevention efforts., (Copyright © 2021 Elsevier Inc. All rights reserved.)

Background: Dementia and cancer are both more common in adults as they age. As new cancer treatments become more popular, it is important to consider how these treatments might affect older patients. This study evaluates metastatic renal cell carcinoma (mRCC) as a risk factor for older adults developing mild cognitive impairment or dementia (MCI/D) and the impact of mRCC-directed therapies on the development of MCI/D., Methods: We identified patients diagnosed with mRCC in a Surveillance, Epidemiology, and End Results (SEER)-Medicare dataset from 2007 to 2015 and matched them to non-cancer controls. Exclusion criteria included age < 65 years at mRCC diagnosis and diagnosis of MCI/D within the year preceding mRCC diagnosis. The main outcome was time to incident MCI/D within one year of mRCC diagnosis for cases or cohort entry for non-cancer controls. Cox proportional hazards models were used to measure associations between mRCC and incident MCI/D as well as associations of oral anticancer agent (OAA) use with MCI/D development within the mRCC group., Results: Patients with mRCC (n = 2533) were matched to non-cancer controls (n = 7027). mRCC (hazard ratio [HR] 8.52, p < .001), being older (HR 1.05 per 1-year age increase, p < .001), and identifying as Black (HR 1.92, p = .047) were predictive of developing MCI/D. In addition, neither those initiating treatment with OAAs nor those who underwent nephrectomy were more likely to develop MCI/D., Conclusions: Patients with mRCC were more likely to develop MCI/D than those without mRCC. The medical and surgical therapies evaluated were not associated with increased incidence of MCI/D. The increased incidence of MCI/D in older adults with mRCC may be the result of the pathology itself or risk factors common to the two disease processes., (Copyright © 2021 Elsevier Ltd.

Introduction: Alcohol use remains a significant contributing factor in traumatic injuries in the United States, resulting in substantial patient morbidity and societal cost. Because of this, the American College of Surgeons Verification, Review, and Consultation Program requires the screening of 80% of trauma admissions. Multiple studies suggest that patients who use alcohol are subject to stigma by health care providers and may ultimately face legal and financial ramifications of a positive alcohol screening test. There is also evidence that sociodemographic factors may dictate drug and alcohol screening patterns among patients. Because this screening target is often not uniformly achieved among all patients presenting with injury, we sought to investigate whether there are any discrepancies in screening across sociodemographic groups., Methods: We investigated the Trauma Quality Program Participant User File for all trauma cases admitted during 2017 and compared the rates of the serum alcohol screening test across different demographic factors, including race and ethnicity. We then performed an adjusted multivariable logistic regression to determine the odds ratio (OR) for receiving a test based on these demographic factors adjusted for hospital and clinical factors., Results: There were 729,174 traumas included in the study. Of this group, 345,315 (47.4%) were screened with a serum alcohol test. Screening rates varied by injury mechanism and were highest among motorcycle crashes (66.0% of patients screened) and lowest among falls (32.8% of patients screened). Overall, Asian and Pacific Islander (52.5% screened), Black (57.7% screened), and other race (58.4% screened) had higher rates of alcohol screening than White patients (43.7% screened, P < 0.001). Similarly, Hispanic patients were screened at higher rates than non-Hispanic patients (56.4% screening versus 46.2% screening, P < 0.001). These differences persisted across nearly all injury categories. In multivariable logistic regression, Asian and Pacific Islanders were associated with the highest odds of being screened (OR 1.34, P < 0.001) followed by other race (OR 1.25, P < 0.001) in comparison to White patients., Conclusions: There are consistent and significant differences in alcohol screening rates across race and ethnicity, despite accounting for injury mechanism and comorbidities., (Copyright © 2022 Elsevier Inc.

Background: Strong epidemiologic evidence linking indicators of geriatric vulnerability to long-term functional outcomes after major surgery is lacking. The objective of this study was to evaluate the association between geriatric vulnerability and the burden of disability after hospital discharge for major surgery., Methods: From a prospective longitudinal study of 754 nondisabled community-living persons, aged 70 years or older, 327 admissions for major surgery were identified from 247 participants who were discharged from the hospital from March 1997 to December 2017. The indicators of geriatric vulnerability were ascertained immediately prior to the major surgery or during the prior comprehensive assessment, which was completed every 18 months. Disability in 13 essential, instrumental and mobility activities was assessed each month., Results: The burden of disability over the 6 months after major surgery was considerably greater for non-elective than elective surgery. In multivariable analysis, 10 factors were independently associated with disability burden: age 85 years or older, female sex, Black race or Hispanic ethnicity, neighborhood disadvantage, multimorbidity, frailty, one or more disabilities, low functional self-efficacy, smoking, and obesity. The burden of disability increased with each additional vulnerability factor, with mean values (credible intervals) increasing from 1.6 (1.4-1.9) disabilities for 0-1 vulnerability factors to 6.6 (6.0-7.2) disabilities for 7 or more vulnerability factors. The corresponding values were 1.2 (0.9-1.5) and 5.9 (5.0-6.7) disabilities for elective surgery and 2.6 (2.1-3.1) and 8.2 (7.3-9.2) disabilities for non-elective surgery., Conclusions: The burden of disability after hospital discharge for major surgery increases progressively as the number of geriatric vulnerability factors increases. These factors can be used to identify older persons who are particularly susceptible to poor functional outcomes after major surgery, and a subset may be amenable to intervention, including frailty, low functional self-efficacy, smoking, and obesity., (© 2022 The American Geriatrics Society.)

Background: Laparoscopy is superior to open surgery for elective colectomy, but its role in emergency colectomy remains unclear. Previous studies were small and limited by confounding because surgeons may have selected lower-risk patients for laparoscopy. We therefore studied the effect of attempting laparoscopy for emergency colectomies while adjusting for confounding using multiple techniques in a large, nationwide registry., Methods: Using National Surgical Quality Improvement Program data, we identified emergency colectomy cases from 2014 to 2018. We first compared outcomes between patients who underwent laparoscopic versus open surgery, while adjusting for baseline variables using both propensity scores and regression. Next, we performed a negative control exposure analysis. By assuming that the group that converted to open did not benefit from the attempt at laparoscopy, we used the observed benefit to bound the effect of unmeasured confounding., Results: Of 21,453 patients meeting criteria, 3,867 underwent laparoscopy, of which 1,375 converted to open. In both inverse probability of treatment weighting and regression analyses, attempting laparoscopy was associated with improved 30-day mortality, overall morbidity, anastomotic leak, surgical site infection, postoperative septic shock, and length of hospital stay compared with open surgery. These effects were consistent with the lower bounds computed from the converted group., Conclusion: Laparoscopic surgery for colorectal emergencies appears to improve outcomes compared with open surgery. The benefit is observed even after adjusting for both measured and unmeasured confounding using multiple statistical approaches, thus suggesting a benefit not attributable to patient selection., (Copyright © 2021 Elsevier Inc.

Objective: To define geographic variations in emergency general surgery (EGS) care, we sought to determine how much variability exists in the rates of EGS operations and subsequent mortality in the Northeastern and Southeastern United States (US)., Summary Background Data: While some geographic variations in healthcare are normal, unwarranted variations raise questions about the quality, appropriateness, and cost-effectiveness of care in different areas., Methods: Patients ≥18 years who underwent 1 of 10 common EGS operations were identified using the State Inpatient Databases (2011-2012) for 6 states, representing Northeastern (New York) and Southeastern (Florida, Georgia, Kentucky, North Carolina, Mississippi) US. Geographic unit of analysis was the hospital service area (HSA). Age-standardized rates of operations and in-hospital mortality were calculated and mapped. Differences in rates across geographic areas were compared using the Kruskal-Wallis test, and variance quantified using linear random-effects models. Variation profiles were tabulated via standardized rates of utilization and mortality to compare geographically heterogenous areas., Results: 227,109 EGS operations were geospatially analyzed across the 6 states. Age-standardized EGS operation rates varied significantly by region (Northeast rate of 22.7 EGS operations per 10,000 in population versus Southeast 21.9; P < 0.001), state (ranging from 9.9 to 29.1; P < 0.001), and HSA (1.9-56.7; P < 0.001). The geographic variability in age-standardized EGS mortality rates was also significant at the region level (Northeast mortality rate 7.2 per 1000 operations vs Southeast 7.4; P < 0.001), state-level (ranging from 5.9 to 9.0 deaths per 1000 EGS operations; P < 0.001), and HSA-level (0.0-77.3; P < 0.001). Maps and variation profiles visually exhibited widespread and substantial differences in EGS use and morality., Conclusions: Wide geographic variations exist across 6 Northeastern and Southeastern US states in the rates of EGS operations and subsequent mortality. More detailed geographic analyses are needed to determine the basis of these variations and how they can be minimized., Competing Interests: The authors report no conflicts of interest., (Copyright © 2020 Wolters Kluwer Health, Inc.

Background: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is being increasingly adopted to manage noncompressible torso hemorrhage, but a recent analysis of the 2015 to 2016 Trauma Quality Improvement Project (TQIP) data set showed that placement of REBOA was associated with higher rates of death, lower extremity amputation, and acute kidney injury (AKI). We expand this analysis by including the 2017 data set, quantifying the potential role of residual confounding, and distinguishing between traumatic and ischemic lower extremity amputation., Methods: This retrospective study used the 2015 to 2017 TQIP database and included patients older than 18 years, with signs of life on arrival, who had no aortic injury and were not transferred. Resuscitative endovascular balloon occlusions of the aorta placed after 2 hours were excluded. We adjusted for baseline variables using propensity scores with inverse probability of treatment weighting. A sensitivity analysis was then conducted to determine the strength of an unmeasured confounder (e.g., unmeasured shock severity/response to resuscitation) that could explain the effect on mortality. Finally, lower extremity injury patterns of patients undergoing REBOA were inspected to distinguish amputation indicated for traumatic injury from complications of REBOA placement., Results: Of 1,392,482 patients meeting the inclusion criteria, 187 underwent REBOA. After inverse probability of treatment weighting, all covariates were balanced. The risk difference for mortality was 0.21 (0.14-0.29) and for AKI was 0.041 (-0.007 to 0.089). For the mortality effect to be explained by an unmeasured confounder, it would need to be stronger than any observed in terms of its relationship with mortality and with REBOA placement. Eleven REBOA patients underwent lower extremity amputation; however, they all suffered severe traumatic injury to the lower extremity., Conclusion: There is no evidence in the TQIP data set to suggest that REBOA causes amputation, and the evidence for its effect on AKI is considerably weaker than previously reported. The increased mortality effect of REBOA is confirmed and could only be nullified by a potent confounder., Level of Evidence: Therapeutic/care management, level IV., (Copyright © 2021 Wolters Kluwer Health, Inc.

Introduction: Anticoagulation (AC) is associated with worse outcomes after trauma in some but not all studies. To further investigate the effect of AC on outcomes in patients with splenic injury, we analyzed the Trauma Quality Programs Participant Use File (PUF) METHODS: The 2017 PUF was used to identify adult (18+ y) with all mechanisms and grades of splenic injury. Demographics, comorbidities, hospital course and outcomes were compared between AC and non-AC patients., Results: A total of 18,749 patients were included, 622 were on AC. The AC patients were older but had comparable gender composition to non-AC patients. Injury Severity Score (18.2 versus 22.5) and rates of serious (AIS ≥ 3) injury were all lower in the AC group (P = 0.001). AC patients received fewer units of RBC (5.7 versus 8.0 units, P < 0.001) and FFP (3.9 versus 5.4 units, P < 0.001) in the first 24 h but underwent angiography at similar rates (23.6 versus 24.5%, P = 0.8). Among those who underwent angiography, patients were more likely to undergo embolization if they were on AC (89.7 versus 73.9%, P = 0.04). Rates of splenic surgery were comparable (19.3 versus 21.5%, P = 0.2) between AC versus non-AC patients. Median LOS was longer in AC patients (6.3 versus 5.6 d, P = 0.002). AC patients had a higher mortality (13.3 versus 7.0%, P = 0.001). In a multivariable binary logistic regression, AC was an independent risk factor for mortality with OR 1.4 (95% CI: 1.1-1.9) CONCLUSIONS: Anticoagulation is associated with increased mortality in patients with splenic injury., Competing Interests: Disclosure The authors reported no proprietary or commercial interest in any product mentioned or concept discussed in this article., (Published by Elsevier Inc.)

Study Objectives: To describe nationwide hospital-based emergency department (ED) closures and mergers, as well as the utilization of emergency departments and inpatient beds, over time and across varying geographic areas in the United States., Methods: Observational analysis of the American Hospital Association (AHA) Annual Survey from 2005 to 2015. Primary outcomes were hospital-based ED closure and merger. Secondary outcomes were yearly ED visits per hospital-based ED and yearly hospital admissions per hospital bed., Results: The total number of hospital-based EDs decreased from 4,500 in 2005 to 4,460 in 2015, with 200 closures, 138 mergers, and 160 new hospital-based EDs. While yearly ED visits per hospital-based ED exhibited a 28.6% relative increase (from 25,083 to 32,248), yearly hospital admissions per hospital bed had a 3.3% relative increase (from 45.4 to 43.9) from 2005 to 2015. The number of hospital admissions and hospital beds did not change significantly in urban areas and declined in rural areas. ED visits grew more uniformly across urban and rural areas., Conclusions: The number of hospital-based ED closures is small when accounting for mergers, but occurs as many more patients are presenting to a stable number of EDs in larger health systems, though rural areas may differentially affected. EDs were managing accelerating patient volumes alongside stagnant inpatient bed capacity., Competing Interests: The authors have declared that no competing interests exist.

Objective: To evaluate the functional effects of intervening illnesses and injuries, that is, events, in the year after major surgery., Background: Intervening events have pronounced deleterious effects on functional status in older persons, but have not been carefully evaluated after major surgery., Methods: From a cohort of 754 community-living persons, aged 70+ years, 317 admissions for major surgery were identified from 244 participants who were discharged from the hospital. Functional status (13 activities) and exposure to intervening hospitalizations, emergency department (ED) visits, and restricted activity were assessed each month. Comprehensive assessments (for covariates) were completed every 18 months., Results: In the year after major surgery, exposure rates (95% CI) per 100-person months to hospitalizations, ED visits, and restricted activity were 10.0 (8.0-12.5), 3.9 (2.8-5.4), and 12.3 (10.2-14.8) for functional recovery and 7.2 (6.1-8.5), 2.5 (1.9-3.2), 11.2 (9.8-12.9) for functional decline. Each of the 3 intervening events were independently associated with reduced recovery, with adjusted hazard ratios (95% CI) of 0.20 (0.09-0.47), 0.35 (0.15-0.81), and 0.57 (0.36-0.90) for hospitalizations, ED visits, and restricted activity. For functional decline, the corresponding odds ratios (95% CI) were 5.68 (3.87-8.33), 1.90 (1.13-3.20), and 1.30 (0.96-1.75). The effect sizes for hospitalizations and ED visits were larger than those for the covariates., Conclusions: Intervening illnesses/injuries are common in the year after major surgery, and those leading to hospitalization and ED visit are strongly associated with adverse functional outcomes, with effect sizes larger than those of traditional risk factors., Competing Interests: The authors report no conflicts of interest., (Copyright © 2020 Wolters Kluwer Health, Inc.

Although the impact of COVID-19 has varied greatly across the United States, there has been little assessment of hospital resources and mortality. We examine hospital resources and death counts among hospital referral regions from March 1 to July 26, 2020. This was an analysis of American Hospital Association data with COVID-19 data from the New York Times. Hospital-based resource availabilities were characterized per COVID-19 case. Death count was defined by monthly confirmed COVID-19 deaths. Geographic areas with fewer intensive care unit beds (incident rate ratio [IRR], 0.194; 95% CI, 0.076-0.491), nurses (IRR, 0.927; 95% CI, 0.888-0.967), and general medicine/surgical beds (IRR, 0.800; 95% CI, 0.696-0.920) per COVID-19 case were statistically significantly associated with an increased incidence rate of death in April 2020. This underscores the potential impact of innovative hospital capacity protocols and care models to create resource flexibility to limit system overload early in a pandemic.

Background: Patients on warfarin with traumatic intracranial hemorrhage often have the warfarin effects pharmacologically reversed. We compared outcomes among patients who received 4-factor prothrombin complex concentrate (PCC), fresh frozen plasma (FFP), or no reversal to assess the real-world impact of PCC on elderly patients with traumatic intracranial hemorrhage (ICH)., Materials and Methods: This was a retrospective analysis of 150 patients on preinjury warfarin. Data were manually abstracted from the electronic medical record of an academic level 1 trauma center for patients admitted between January 2013 and December 2018. Outcomes were ICH progression on follow-up computed tomography scan, mortality, need for surgical intervention, and trends in the use of reversal agents., Results: Of 150 patients eligible for analysis, 41 received FFP, 60 PCC, and 49 were not reversed. On multivariable analysis, patients not reversed [OR 0.25 95% CI (0.31-0.85)] and women [OR 0.38 95% CI (0.17-0.88)] were less likely to experience progression of their initial bleed on follow-up computed tomography while subdural hemorrhage increased the risk [OR 3.69 95% CI (1.27-10.73)]. There was no difference between groups in terms of mortality or need for surgery. Over time use of reversal with PCC increased while use of FFP and not reversing warfarin declined (P < 0.001)., Conclusions: Male gender and using a reversal agent were associated with progression of ICH. Choice of reversal did not impact the need for surgery, hospital length of stay, or mortality. Some ICH patients may not require warfarin reversal and may bias studies, especially retrospective studies of warfarin reversal., (Copyright © 2020 Elsevier Inc. All rights reserved.)

Background: Benzodiazepine is first-line therapy for alcohol withdrawal syndrome (AWS), and phenobarbital is an alternative therapy. However, its use has not been well validated in the surgical-trauma patient population., Objective: To describe the use of fixed-dose phenobarbital monotherapy for the management of patients at risk for AWS in the surgical-trauma intensive care unit., Methods: Surgical-trauma critically ill patients who received phenobarbital monotherapy, loading dose followed by a taper regimen, for the management of AWS were included in this evaluation. The effectiveness of phenobarbital monotherapy to treat AWS and prevent development of AWS-related complications were evaluated. Safety end points assessed included significant hypotension, bradycardia, respiratory depression, and need for invasive mechanical ventilation., Results: A total of 31 patients received phenobarbital monotherapy; the majority of patients were at moderate risk for developing AWS (n = 20; 65%) versus high risk (n = 11; 35%). None of the patients developed AWS-related complications; all patients were successfully managed for their AWS. Nine patients (29%) received nonbenzodiazepine adjunct therapy for agitation post-phenobarbital initiation. Three patients (10%) experienced hypotension, and 3 (10%) were intubated. None of the patients had clinically significant bradycardia or respiratory depression., Conclusion and Relevance: Fixed-dose phenobarbital monotherapy appears to be well tolerated and effective in the management of AWS. Further evaluation is needed to determine the extent of benefit with the use of phenobarbital monotherapy for management of AWS.

Background: Trauma-related disorders rank among the top five most costly medical conditions to the health care system. However, the impact of out-of-pocket (OOP) health expenses for traumatic conditions is not known. In this cross-sectional study, we use nationally representative data to investigate whether patients with a traumatic injury experienced financial hardship from OOP health expenses., Methods: Using data from the Medical Expenditure Panel Survey from 2010 to 2015, we analyzed the financial burden associated with a traumatic injury. Primary outcomes were excess financial burden (OOP>20% of annual income) and catastrophic medical expenses (OOP>40% of annual income). A multivariable logistic regression analysis evaluated whether these outcomes were associated with traumatic injury, adjusting for demographic, socioeconomic, and health care factors. We then completed a descriptive analysis to elucidate drivers of total OOP expenses., Results: Of the 90,964 families in the cohort, 6434 families had a traumatic injury requiring a visit to the emergency room and 668 families had a traumatic injury requiring hospitalization. Overall 1 in 8 households with an injured family member requiring hospitalization experienced financial hardship. These families were more likely to experience excess financial burden (OR: 2.04, 95% CI: 1.13-3.64) and catastrophic medical expenses (OR: 3.08, 95% CI: 1.37-6.9). The largest burden of OOP expenses was due to prescription drug costs, with inpatient costs as a major driver of OOP expenses for those requiring hospitalization., Conclusions: Households with an injured family member requiring hospitalization are significantly more vulnerable to financial hardship from OOP health expenses than the noninjured population. Prescription drug and inpatient costs were the most significant drivers of OOP health expenses., (Copyright © 2020 Elsevier Inc. All rights reserved.)

Objective: This study aimed to answer 2 questions: first, to what degree does hospital operative volume affect mortality for adult patients undergoing 1 of 10 common emergency general surgery (EGS) operations? Second, at what hospital operative volume threshold will nearly all patients undergoing an emergency operation realize the average mortality risk?, Background: Nontrauma surgical emergencies are an underappreciated public health crisis in the United States; redefining where such emergencies are managed may improve outcomes. The field of trauma surgery established regionalized systems of care in part because studies demonstrated a clear relationship between hospital volume and survival for traumatic emergencies. Such a relationship has not been well-studied for nontrauma surgical emergencies., Methods: Retrospective cohort study of all acute care hospitals in California performing nontrauma surgical emergencies. We employed a novel use of an ecological analysis with beta regression to investigate the relationship between hospital operative volume and mortality., Results: A total of 425 acute care hospitals in California performed 165,123 EGS operations. Risk-adjusted mortality significantly decreased as volume increased for all 10 EGS operations (P < 0.001 for each); the relative magnitude of this inverse relationship differed substantially by procedure. Hospital operative volume thresholds were defined and varied by operation: from 75 cases over 2 years for cholecystectomy to 7 cases for umbilical hernia repair., Conclusions: Survival rates for nontrauma surgical emergencies were improved when operations were performed at higher-volume hospitals. The use of ecological analysis is widely applicable to the field of surgical outcomes research.

Background: Survivors of gun violence may develop significant mental health sequelae and are at higher risk for reinjury through repeat violence. Despite this, survivors of gun violence often return to the community where they were injured with suboptimal support for their mental health, emotional recovery, and well-being. The goal of this study was to characterize the posthospitalization recovery experience of survivors of gun violence., Methods: We conducted a qualitative research study with a community-based participatory research approach. In partnership with a community-based organization, we conducted in-depth one-on-one interviews and used snowball sampling to recruit survivors of gun violence. We applied the constant comparison method of qualitative analysis to catalogue interview transcript data by assigning conceptual codes and organizing them into a consensus list of themes. We presented the themes back to the participants and community members for confirmation., Results: We conducted 20 interviews with survivors of gun violence; all were black men, aged 20 years to 51 years. Five recurring themes emerged: (1) Isolation, physical and social restriction due to fear of surroundings; (2) Protection, feeling unsafe leading to the desire to carry a gun; (3) Aggression, willingness to use a firearm in an altercation; (4) Normalization, lack of reaction driven by the ubiquity of gun violence in the community; and (5) Distrust of health care providers, a barrier to mental health treatment., Conclusion: Survivors of gun violence describe a disrupted sense of safety following their injury. As a result, they experience isolation, an increased need to carry a firearm, a normalization of gun violence, and barriers to mental health treatment. These maladaptive reactions suggest a mechanism for the violent recidivism seen among survivors of gun violence and offer potential targets to help this undertreated, high-risk population., Level of Evidence: Care management/Therapeutic V.

Objective: The objectives of the current study were 2-fold: first, to evaluate the incidence and time to recovery of premorbid function within 6 months of major surgery and second, to identify factors associated with functional recovery among older persons who survive a major surgery with increased disability., Background: Most older persons would not choose a surgical treatment resulting in persistently increased postsurgical disability, even if survival was assured. Potential predictors of functional recovery after major surgery have, however, not been well-studied among geriatric patients., Methods: It is a prospective longitudinal study of 754 community-living persons 70 years or older. The analytic sample included 266 person-admissions in which participants survived major surgery with increased disability and were monitored on a monthly basis for 6 months., Results: Of the 266 person-admissions assessed, 174 (65.4%) recovered to their presurgical level of function, with median time to recovery of 2 months (interquartile range, 1-3), whereas 16 (6.0%) died. Two factors were significantly associated with an increased likelihood of functional recovery: being nonfrail (hazard ratio 1.60; 95% confidence interval 1.03-2.51; P = 0.038) and having elective surgery (hazard ratio 1.72; 95% confidence interval 1.14-2.59; P = 0.009). Three factors were associated with a reduced likelihood of functional recovery: hearing impairment, greater increase in postsurgical disability in the month after hospital discharge, and years of education., Conclusions: Among older persons, nonfrailty and elective surgery were positively associated with functional recovery, whereas hearing impairment, greater increases in postsurgical disability, and years of education were associated with higher risk of protracted disability.

Background: The American College of Surgeons maintains that surgical care in the US has not reached optimal safety and quality. This can be driven partially by higher-risk, emergency operations in geriatric patients. We therefore sought to answer 2 questions: First, to what degree does standardized postoperative mortality vary in hospitals performing nonelective operations in geriatric patients? Second, can the differences in hospital-based mortality be explained by patient-, operative-, and hospital-level characteristics among outlier institutions?, Study Design: Patients 65 years and older who underwent 1 of 8 common emergency general surgery operations were identified using the California State Inpatient Database (2010 to 2011). Expected mortality was obtained from hierarchical, Bayesian mixed-effects logistic regression models. A risk-adjusted hospital-level standardized mortality ratio (SMR) was calculated from observed-to-expected in-hospital deaths. "Outlier" hospitals had an SMR 80% CI that did not cross the mean SMR of 1.0. High-mortality (SMR >1.0) and low-mortality (SMR <1.0) outliers were compared., Results: We included 24,207 patients from 107 hospitals. SMRs varied widely, from 2.3 (highest) to 0.3 (lowest). Eleven hospitals (10.3%) were poor-performing high-SMR outliers, and 10 hospitals (9.3%) were exceptional-performing low-SMR outliers. SMR was 3 times worse in the high-SMR compared with the low-SMR group (1.7 vs 0.6; p < 0.001). Patient-, operation-, and hospital-level characteristics were equivalent among outlier-hospitals., Conclusions: Significant hospital variation exists in standardized mortality after common general surgery operations done emergently in older patients. More than 10% of institutions have substantial excess mortality. These findings confirm that the safety of emergency operation in geriatric patients can be significantly improved by decreasing the wide variability in mortality outcomes., (Copyright © 2020 American College of Surgeons.

Background: It has been theorized that a tiered, regionalized system of care for emergency general surgery (EGS) patients-akin to regional trauma systems-would translate into significant survival benefits. Yet data to support this supposition are lacking. The aim of this study was to determine the potential number of lives that could be saved by regionalizing EGS care to higher-volume, lower-mortality EGS institutions., Methods: Adult patients who underwent one of 10 common EGS operations were identified in the California Inpatient Database (2010-2011). An algorithm was constructed that "closed" lower-volume, higher-mortality hospitals and referred those patients to higher-volume, lower-mortality institutions ("closure" based on hospital EGS volume-threshold that optimized to 95% probability of survival). Primary outcome was the number of lives saved. Fifty thousand regionalization simulations were completed (5,000 for each operation) employing a bootstrap resampling method to proportionally redistribute patients. Estimates of expected deaths at the higher-volume hospitals were recalculated for every bootstrapped sample., Results: Of the 165,123 patients who underwent EGS operations over the 2-year period, 17,655 (10.7%) were regionalized to a higher-volume hospital. On average, 128 (48.8%) of lower-volume hospitals were "closed," ranging from 68 (22.0%) hospital closures for appendectomy to 205 (73.2%) for small bowel resection. The simulations demonstrated that EGS regionalization would prevent 9.7% of risk-adjusted EGS deaths, significantly saving lives for every EGS operation: from 30.8 (6.5%) deaths prevented for appendectomy to 122.8 (7.9%) for colectomy. Regionalization prevented 4.6 deaths per 100 EGS patient-transfers, ranging from 1.3 for appendectomy to 8.0 for umbilical hernia repair., Conclusion: This simulation study provides important new insight into the concept of EGS regionalization, suggesting that 1 in 10 risk-adjusted deaths could be prevented by a structured system of EGS care. Future work should expand upon these findings using more complex discrete-event simulation models., Level of Evidence: Therapeutic/Care Management, level IV.

Background: Expected performance rates for various outcome metrics are a hallmark of hospital quality indicators used by Agency of Healthcare Research and Quality, Center for Medicare and Medicaid Services, and National Quality Forum. The identification of outlier hospitals with above- and below-expected mortality for emergency general surgery (EGS) operations is therefore of great value for EGS quality improvement initiatives. The aim of this study was to determine hospital variation in mortality after EGS operations, and compare characteristics between outlier hospitals., Methods: Using data from the California State Inpatient Database (2010-2011), we identified patients who underwent one of eight common EGS operations. Expected mortality was obtained from a Bayesian model, adjusting for both patient- and hospital-level variables. A hospital-level standardized mortality ratio (SMR) was constructed (ratio of observed to expected deaths). Only hospitals performing three or more of each operation were included. An "outlier" hospital was defined as having an SMR with 80% confidence interval that did not cross 1.0. High- and low-mortality SMR outliers were compared., Results: There were 140,333 patients included from 220 hospitals. Standardized mortality ratio varied from a high of 2.6 (mortality, 160% higher than expected) to a low of 0.2 (mortality, 80% lower than expected); 12 hospitals were high SMR outliers, and 28 were low SMR outliers. Standardized mortality was over three times worse in the high SMR outliers compared with the low SMR outliers (1.7 vs. 0.5; p < 0.001). Hospital-, patient-, and operative-level characteristics were equivalent in each outlier group., Conclusion: There exists significant hospital variation in standardized mortality after EGS operations. High SMR outliers have significant excess mortality, while low SMR outliers have superior EGS survival. Common hospital-level characteristics do not explain the wide gap between underperforming and overperforming outlier institutions. These findings suggest that SMR can help guide assessment of EGS performance across hospitals; further research is essential to identify and define the hospital processes of care which translate into optimal EGS outcomes., Level of Evidence: Epidemiologic Study, level III.

Background: There is a longstanding interest in the field of management science to study high performance organizations. Applied to medicine, research on hospital performance indicates that some hospitals are high performing, while others are not. The objective of this study was to identify a cluster of high-performing emergency general surgery (EGS) hospitals and assess whether high performance at one EGS operation was associated with high performance on all EGS operations., Methods: Adult patients who underwent one of eight EGS operations were identified in the California State Inpatient Database (2010-2011), which we linked to the American Hospital Association database. Beta regression was used to estimate a hospital's risk-adjusted mortality, accounting for patient- and hospital-level factors. Centroid cluster analysis grouped hospitals by patterns of mortality rates across the eight EGS operations using z scores. Multinomial logistic regression compared hospital characteristics by cluster., Results: A total of 220 acute care hospitals were included. Three distinct clusters of hospitals were defined based on assessment of mortality for each operation type: high-performing hospitals (n = 66), average performing (n = 99), and low performing (n = 55). The mortality by individual operation type at the high-performing cluster was consistently at least 1.5 standard deviations better than the low-performing cluster (p < 0.001). Within-cluster variation was minimal at high-performing hospitals compared with wide variation at low-performing hospitals. A hospital's high performance in one EGS operation type predicted high performance on all EGS operation types., Conclusion: High-performing EGS hospitals attain excellence across all types of EGS operations, with minimal variability in mortality. Poor-performing hospitals are persistently below average, even for low-risk operations. These findings suggest that top-performing EGS hospitals are highly reliable, with systems of care in place to achieve consistently superior results. Further investigation and collaboration are needed to identify the factors associated with high performance., Level of Evidence: Prognostic, level III.

Background: As the geriatric population grows, the need for hospitals performing high quality emergency general surgery (EGS) on older patients will increase. Identifying clusters of high-performing geriatric emergency general surgery hospitals would substantiate the need for in-depth analyses of hospital-specific structures and practices that benefit older EGS patients. The objectives of this study were therefore to identify clusters of hospitals based on mortality performance for geriatric patients undergoing common EGS operations and to determine if hospital performance was similar for all operation types., Methods: Hospitals in the California State Inpatient Database were included if they performed a range of eight common EGS operations in patients 65 years or older, with a minimum requirement of three of each operation performed over 2 years. Multivariable beta regression models were created to define hospital-level risk-adjusted mortality. Centroid cluster analysis was used to identify groups of hospitals based on mortality and to determine if mortality-performance differed by operation., Results: One hundred seven hospitals were included, performing a total of 24,279 operations in older patients. Hospitals separated into three distinct clusters: high, average, and low performers. The high-performing hospitals had survival rates 1 to 2 standard deviations better than the low-performers (p < 0.001). For each cluster, high performance in any one EGS operation consistently translated into high performance across all EGS operations., Conclusion: Hospitals conducting EGS operations in the geriatric patient population cluster into three distinct groups based on their survival performance. High-performing hospitals significantly outperform the average and low performers across every operation. The high-performers achieve reliable, high-quality results regardless of operation type. Further qualitative research is needed to investigate the perioperative drivers of hospital performance in the geriatric EGS population., Level of Evidence: Study Type Prognostic, level III.

Background: Within the growing geriatric population, there is an increasing need for emergency operations. Optimizing outcomes can require a structured system of surgical care based on key quality indicators. To investigate this, the current study sought to answer 2 questions. First, to what degree does hospital emergency operative volume impact mortality for geriatric patients undergoing emergency general surgery (EGS) operations? Second, at what procedure-specific hospital volume will geriatric patients undergoing an emergency operation achieve at or better than average mortality risk?, Study Design: Retrospective cohort study of geriatric patients (aged 65 years and older) who underwent 1 of 10 EGS operations identified from the California State Inpatient Database (2010 to 2011). β-Logistic generalized linear regression was used, with the hospital as the unit of analysis, to investigate the relationship between hospital operative volume and in-hospital riskv-adjusted mortality. Hospital operative volume thresholds to optimize probability of survival were defined., Results: There were 41,860 operations evaluated at 299 hospitals. For each operation, mortality decreased as hospital emergency operative volume increased (p < 0.001 for each operation); for every standardized increase in volume (meaning +1 natural logarithm of volume), the reduction in mortality ranged from 14% for colectomy to 61% for appendectomy. Hospital volume thresholds, which optimize to 95% probability of survival, varied by procedure, with a mean of 14 operations over 2 years. More than 50% of hospitals did not meet the threshold benchmarks, representing 22% of patients., Conclusions: Survival rates for geriatric patients were improved substantially when emergency operations were performed at hospitals with higher operative volumes. Consistent with all active Quality Programs of the American College of Surgeons, hospital operative volume appears to be an important metric of surgical quality for older patients undergoing emergency operations., (Copyright © 2019 American College of Surgeons.

Background: The postoperative outcomes of emergency general surgery patients can be fraught with uncertainty. Although surgical risk calculators exist to predict 30-day mortality, they are often of limited utility in preparing patients and families for immediate perioperative complications. Examination of trends in mortality after emergent colectomy may help inform complex perioperative decision-making. We hypothesized that risk factors could be identified to predict early mortality (before postoperative day 5) to inform operative decisions., Methods: This analysis was a retrospective cohort study using the American College of Surgeons National Surgical Quality Improvement Program database (2012-2014). Patients were stratified into three groups: early death (postoperative day 0-4), late death (postoperative day 5-30), and those who survived. Multivariable logistic regression was used to explore characteristics associated with early death. Kaplan-Meier models and Cox regression were used to further characterize their impact., Results: A total of 18 803 patients were analyzed. Overall 30-day mortality was 12.5% (3316); of these, 37.1% (899) were early deaths. The preoperative factors most predictive of early death were septic shock (OR 3.62, p<0.001), ventilator dependence (OR 2.81, p<0.001), and ascites (OR 1.63, p<0.001). Postoperative complications associated with early death included pulmonary embolism (OR 5.78, p<0.001), presence of new-onset or ongoing postoperative septic shock (OR 4.45, p<0.001) and new-onset renal failure (OR 1.89, p<0.001). Patients with both preoperative and postoperative shock had an overall mortality rate of 47% with over half of all deaths occurring in the early period., Conclusions: Nearly 40% of patients who die after emergent colon resection do so before postoperative day 5. Early mortality is heavily influenced by the presence of both preoperative and new or persistent postoperative septic shock. These results demonstrate important temporal trends of mortality, which may inform perioperative patient and family discussions and complex management decisions., Level of Evidence: Level III. Study type: Prognostic., Competing Interests: Competing interests: None declared.

Objectives: We hypothesized that distinct sets of functional trajectories can be identified in the year before and after major surgery, with unique transition probabilities from pre to postsurgical functional trajectories, and that outcomes would be better among participants undergoing elective versus nonelective surgery., Background: Major surgery is common and can be highly morbid in older persons. The relationship between the course of disability (ie, functional trajectory) before and after surgery in older adults has not been well-studied for most operations., Methods: Prospective cohort study of 754 community-living persons 70 years or older. The analytic sample included 250 participants who underwent their first major surgery during the study period., Results: Before surgery, 4 functional trajectories were identified: no disability (n = 60, 24.0%), and mild (n = 84, 33.6%), moderate (n = 73, 29.2%), and severe (n = 33, 13.2%) disability. After surgery, 4 functional trajectories were identified: rapid (n = 39, 15.6%), gradual (n = 76, 30.4%), partial (n = 70, 28.0%), and little (n = 57, 22.8%) improvement. Rapid improvement was seen for n = 31 (51.7%) participants with no disability before surgery, but was uncommon among those with mild disability (n = 8, 9.5%) and was not observed in the moderate and severe trajectory groups. For participants with mild to moderate disability before surgery, gradual improvement (n = 46, 54.8%) and partial improvement (n = 36, 49.3%) were most common. Most participants with severe disability (n = 27, 81.8%) before surgery exhibited little improvement. Outcomes were better for participants undergoing elective versus nonelective surgery., Conclusions: Functional prognosis in the year after major surgery is highly dependent on premorbid function.

Background: Patients requiring emergency surgery have increased rates of morbidity and mortality. Transfer from outside institution delays effective control of ongoing infection and has been linked with worse outcomes. Previous research suggests transfer status negatively impacts survival but has not examined the effect of location and type of institution prior to transfer. This study aims to characterize the effect of type of transferring institution on postoperative outcomes after emergency colon surgery., Methods: Data originated from the American College of Surgeons National Surgical Quality Improvement Program database from 2010 to 2012. Patients undergoing emergent colectomy were stratified based on location: not transferred, transferred from outside emergency department (ED), transferred from outside hospital inpatient unit, or transferred from a nursing home. Patient variables were stratified and compared via χ and analysis of variance. A backward-multivariable logistic regression and adjusted multivariate Cox regression analysis were performed to determine factors predicting 30-day mortality., Results: A total of 14,245 patients were identified, of whom 22% (3,203) were transfer patients. Among transfers, 48% (1,531) came from outside hospital inpatient units. Thirty-day mortality varied significantly (p < 0.001) among transfer location: 12.8% when not transferred, 19.4% from outside EDs, 25.7% from outside hospital inpatient units, and 34.2% from nursing homes. Hazard ratios were 1.30 (p < 0.001) after transfer from outside hospital inpatient ward and 1.50 (p < 0.001) after transfer from nursing home. Patients transferred from nursing homes were more likely to have septic shock (26.9% vs. 11.6%, p < 0.001) and longer hospitalizations (13 days vs. 10 days, p < 0.001) versus those not transferred., Conclusion: Transfer status is an independent contributor to death in emergency general surgery patients undergoing colectomy. Patients transferred from an outside hospital ED, nursing home or chronic care facility have the poorest outcomes. These results reinforce the importance of rapid triage and transfer of patients with early physiologic decompensation to ensure timely surgical evaluation and intervention., Level of Evidence: Prognostic, level III; Therapeutic, level IV.
