Investigating the 2016 surge in firearm violence in Illinois, USA, through community-based organisations: a qualitative study.

BACKGROUND: Illinois experienced a historic firearm violence surge in 2016 with a decline to baseline rates in 2018. This study aimed to understand this 2016 surge through the direct accounts of violence prevention community-based organisations (CBOs) in Illinois. METHODS: We conducted semistructured interviews with 20 representatives from 13 CBOs from the south and west sides of greater Chicago metropolitan area. Interviews were audio recorded, coded and analysed thematically. RESULTS: We identified lack of government-derived infrastructure and systemic poverty as the central themes of Illinois's 2016 firearm violence surge. Participants highlighted the Illinois Budget Impasse halted funding for violence prevention efforts, leading to 2016's violence. This occurred in the context of a strained relationship with the criminal justice system, where disengagement from police and mistrust in the justice system led victims and families to seek justice outside of the judicial system. Participants emphasised that systemic poverty and the obliteration of community support structures led to overwhelming desperation, which, in turn, increased risky behaviours perceived as necessary for survival. Participants disproportionately identified that this impacted the young people in their communities. CONCLUSIONS: Lack of government-derived infrastructure and systemic poverty were the central themes of the 2016 firearm violence surge. The insights gained from the 2016 surge are applicable to understanding both current and future surges. CBOs focused on violence prevention offer insights into the context and conditions fuelling surges in the epidemic of violence.

Exploratory qualitative study of firearm storage practices among surgeons in the USA: contexts and motivations.

BACKGROUND: A US survey of surgeons found that 32% store firearms unlocked and loaded. This study explored conditions and contexts impacting personal firearm storage methods among surgeons. METHODS: We conducted semi-structured interviews with English-speaking fellows of the American College of Surgeons who treated patients injured by firearms and who owned or lived in homes with firearms. Participants were recruited through email and subsequent snowball sampling from April 2022 to August 2022. All interviews were audio-recorded and transcribed verbatim. Thematic analysis was applied to transcripts to identify codes. A mixed deductive and inductive approach was used for data reduction and sorting. RESULTS: A total of 32 surgeons were interviewed; most were male and white. Dominant themes for firearm storage practices were based on (1) attitudes; (2) perceived norms; (3) personal agency; and (4) intention of firearm use. Personal agency often conflicted with attitudes and perceived norms for surgeons owning firearms for self-defence. CONCLUSIONS: Storage practices in this sample of firearm-owning surgeons were driven by intent for firearm use, coupled with attitudes, perceived norms and personal agency. Personal agency often conflicted with attitudes and perceived norms, especially for surgeons who owned their firearm for self-defence.

The association between gun shows and firearm injuries: An analysis of 259 gun shows across 23 US cities.

Guns shows are estimated to account for 4-9% of firearm sales in the US. Increased regulation of firearm sales at gun shows has been proposed as one approach to reducing firearm injury rates. This study evaluated the association between gun shows and local firearm injury rates. Data regarding the date and location of gun shows from 2017 to 2019 were abstracted from the Big Show Journal. Firearm injury rates were estimated using discharges from trauma centers serving counties within a 25-mile radius of each gun show. Clinical data were derived from the National Trauma Databank (NTDB). We used Poisson regression modeling to adjust for potential confounders including seasonality. We evaluated injury rates before and after 259 gun shows in 23 US locations using firearm injury data from 36 trauma centers. There were 1513 hospitalizations for firearm injuries pre-gun show and 1526 post-gun show. The adjusted mean 2-week rate of all-cause firearm injury per 1,000,000 person-years was 1.79 (1.16-2.76) before and 1.82 (1.18-2.83) after a gun show, with an incident rate ratio of 1.02 (0.94, 1.08). The adjusted mean 2-week rate did not vary significantly by intent after a gun show, (p = 0.24). Within two weeks after a gun show, rates of hospitalization for all-cause firearm injury do not increase significantly within the surrounding communities. The relatively small increase in available firearms after a show and the short time horizon evaluated may account for the absence of an association between gun show firearm sales and local firearm injury rates.

A Qualitative study on diverse perspectives and identities of firearm owners.

OBJECTIVE: Research surrounding firearm ownership is often contextualised within the perspectives of older white men. We expand this description using the perceptions of a diverse group of firearm-owning stakeholders. METHODS: We conducted semistructured interviews from October 2020 to May 2021 with Colorado/Washington State stakeholders representing (1) firearm ranges/retailers; (2) law enforcement agencies or (3) relevant state/national firearm organisations. Data were analysed using standard qualitative techniques and included 25 participants, representing varied sociocultural groups including racial and ethnic minorities, political minorities and sexual minorities. RESULTS: Participants for this analysis were of different self-identified sociocultural groups including racial and ethnic minorities (African American, Hispanic and Asian), political minorities (liberal) and sexual minorities, defined as Lesbian, Gay, Bisexual, and Transgender (LGBT). Perspectives on firearm ownership included an idea of gun culture as a component of (1) personal identity, (2) an expression of full citizenship and (3) necessary for self-protection. A strong subtheme was the intersection of minority group and firearm owner identities, creating a need for divergent social communities because of ideas on traditional gun culture. These communities are a safe place for individuals belonging to minority groups to escape negative external and internal group associations with firearms. CONCLUSION: Perspectives on firearms and firearm ownership in the secondary analysis were heterogeneous and related to personal experiences, external and internal group pressures that influence individual behaviour. Understanding the breadth of perspectives on firearm ownership is imperative to engaging individuals for risk reduction. This study adds to the literature by expanding an understanding of the motivation for firearm ownership among diverse communities.

Long-term Outcomes of Firearm Injury Survivors in the United States: The National Trauma Research Action Plan Scoping Review.

SUMMARY BACKGROUND/OBJECTIVE: To describe the current literature regarding long-term physical, mental, and social outcomes of firearm injury survivors in the United States. METHODS: We systematically searched the PubMed/MEDLINE and Embase databases for articles published from 2013 to 2019 that involved survivors of acute physical traumatic injury aged 18 or older and reported health outcomes between 6 months and 10 years postinjury. Out of 747 articles identified, seven reported outcomes on United States-based civilian patients whose mechanism of injury involved firearms. We extended our publication date criteria from 1995 to 2020 and expanded the search strategy to include medical subject headings terms specific for firearm injury outcomes. Ultimately, ten articles met inclusion criteria. RESULTS: When studied, a significant proportion of patients surviving firearm injury screened positive for posttraumatic stress disorder (49%-60%) or were readmitted (13%-26%) within 6 months postinjury. Most studies reported worse long-term outcomes for firearm injury survivors when compared both to similarly injured motor vehicle collision survivors and to the United States general population, including increased chronic pain, new functional limitations, and reduced physical health composite scores. Studies also reported high rates of posttraumatic stress disorder, reduced mental health composite scores, lower employment and return to work rates, poor social functioning, increased alcohol, and substance abuse. CONCLUSIONS: Research on the long-term health impact of firearm injury is scant, and heterogeneity in available studies limits the ability to fully characterize the outcomes among these patients. A better understanding of the long-term health impact of firearm injury would support systematic change in policy and patient care to improve outcomes.

Complications from Needle Thoracostomy: Penetration of the Myocardium.

We report a rare but serious complication of needle thoracostomy, penetration of the myocardium. Needle thoracostomy is typically performed in the prehospital setting or upon arrival in the emergency department for suspected tension pneumothorax. Needle decompression is generally taught and done anteriorly, in the 2nd intercostal space on the midclavicular line (MCL). An alternative approach is laterally, along the anterior axillary line (AAL) in the 4th intercostal space. Our case supports prior literature that the anterior MCL location has a low rate of efficacy to decompress the chest, as well as a high rate of complications. We recommend performing needle decompression laterally at the AAL whether in the field or in the emergency department.

Pelvic organ prolapse: An unusual cause of small bowel obstruction.

We present the rare case of a small bowel obstruction secondary to pelvic organ prolapse (POP). A 77-year-old female presented with four days of abdominal pain, nausea, and vomiting. She had a history of abdominal hysterectomy with bilateral salpingo-opherectomy and a mildly symptomatic cystocele. She was found to have an enterocele causing small bowel obstruction. The enterocele was manually reduced and subsequently managed non-operatively with a pessary. Prior case reports of small bowel obstructions secondary to POP required emergent surgical intervention. Post-menopausal women should be asked about symptoms or presence of pelvic organ prolapse and in the correct patient population, pelvic examination can be important for diagnosis and treatment of small bowel obstruction. If the enterocele is manually reduced non-operative management can be safe and effective.

Impact of Medicaid Expansion and Firearm Legislation on Cost of Firearm Injuries.

INTRODUCTION: Firearm injury-related hospitalizations in the U.S. cost $900 million annually. Before the Affordable Care Act, government insurance programs covered 41% of the costs. This study describes the impact of Affordable Care Act Medicaid expansion and state-level firearm legislation on coverage and costs for firearm injuries. METHODS: This cross-sectional study included 35,854,586 hospitalizations from 27 states in 2013 and 2016. Data analyses were performed in 2022. Firearm injuries were classified by mechanism: assault, unintentional, self-harm, or undetermined. The impact of the Affordable Care Act expansion was determined using difference-in-differences analysis. Differences in per capita costs between states with stronger and weak firearm legislation were compared using univariable and multivariable analyses. RESULTS: The authors identified 31,451 initial firearm injury-related hospitalizations. In states with weak firearm legislation, hospitalization costs per 100,000 residents were higher from unintentional ($25,834; p=0.04) and self-inflicted ($11,550; p=0.02) injuries; there were no state-level differences in assault or total per capita firearm-related hospitalization costs. Affordable Care Act expansion increased government coverage of costs by 15 percentage points (95% CI=3, 29) and decreased costs to uninsured/self-pay by 14 percentage points (95% CI=6, 21). In 2016, states with weak firearm legislation and no Affordable Care Act expansion had the highest proportion of hospitalization costs attributed to uninsured/self-pay patients (24%, 95% CI=15, 34). CONCLUSIONS: Affordable Care Act expansion increased government coverage of hospitalizations for firearm injuries. Unintentional and self-harm costs were significantly higher for states with weak firearm legislation. States with weak firearm legislation that did not expand Medicaid had the highest proportion of uninsured/self-pay patients.

Appendicitis Hospitalization Care Costs Among Patients With Delayed Diagnosis of Appendicitis.

Importance: Delayed appendicitis diagnosis is associated with worse outcomes. Appendicitis hospital care costs associated with delayed diagnosis are unknown. Objective: To determine whether delayed appendicitis diagnosis was associated with increased appendicitis hospital care costs. Design, Setting, and Participants: This cohort study used data from patients receiving an appendectomy aged 18 to 64 years in 5 states (Florida, Maryland, Massachusetts, New York, Wisconsin) that were captured in the Healthcare Cost and Utilization Project State Inpatient and Emergency Department databases for the years 2016 and 2017 with no additional follow-up. Data were analyzed January through April 2023. Exposures: Delayed diagnosis was defined as a previous emergency department or inpatient hospital encounter with an abdominal diagnosis other than appendicitis, and no intervention 7 days prior to appendectomy encounter. Main Outcomes and Measures: The main outcome was appendicitis hospital care costs. This was calculated from aggregated charges of encounters 7 days prior to appendectomy, the appendectomy encounter, and 30 days postoperatively. Cost-to-charge ratios were applied to charges to obtain costs, which were then adjusted for wage index, inflation to 2022 US dollar, and with extreme outliers winsorized. A multivariable Poisson regression estimated appendicitis hospital care costs associated with a delayed diagnosis while controlling for age, sex, race and ethnicity, insurance status, care discontinuity, income quartile, hospital size, teaching status, medical school affiliation, percentage of Black and Hispanic patient discharges, core-based statistical area, and state. Results: There were 76 183 patients (38 939 female [51.1%]; 2192 Asian or Pacific Islander [2.9%], 14 132 Hispanic [18.5%], 8195 non-Hispanic Black [10.8%], 46 949 non-Hispanic White [61.6%]) underwent appendectomy, and 2045 (2.7%) had a delayed diagnosis. Delayed diagnosis patients had median (IQR) unadjusted cost of $11 099 ($6752-$17 740) compared with $9177 ($5575-$14 481) for nondelayed (P < .001). Patients with delayed diagnosis had 1.23 times (95% CI, 1.16-1.28 times) adjusted increased appendicitis hospital care costs. The mean marginal cost of delayed diagnosis was $2712 (95% CI, $2083-$3342). Even controlling for delayed diagnosis, non-Hispanic Black patients had 1.22 times (95% CI, 1.17-1.28 times) the adjusted increased appendicitis hospital care costs compared with non-Hispanic White patients. Conclusions and Relevance: In this cohort study, delayed diagnosis of appendicitis was associated with increased hospital care costs.

Patient and Hospital Characteristics Associated with Admission Among Patients With Minor Isolated Extremity Firearm Injuries: A Propensity-Matched Analysis.

Objective: To quantify the association between insurance and hospital admission following minor isolated extremity firearm injury. Background: The association between insurance and injury admission has not been examined. Methods: This was an observational retrospective cohort study of minor isolated extremity firearm injury captured in the Healthcare Cost and Utilization Project State Inpatient and Emergency Department Databases in 6 states (New York, Arkansas, Wisconsin, Massachusetts, Florida, and Maryland) from 2016 to 2017 among patients aged 16 years or older. The primary exposure was insurance. Admitted patients were propensity score matched to nonadmitted patients on age, extremity Abbreviated Injury Score, and Elixhauser Comorbidity Index with exact matching within hospital to adjust for selection bias. A general estimating equation logistic regression estimated the association between insurance and odds of admission in the matched cohort while controlling for sex, race, injury intent, injury type, hospital profit type, and trauma center designation with observations clustered by propensity score-matched pairs within hospital. Results: A total of 8151 patients presented to hospital with a minor isolated extremity firearm injury between 2016 and 2017 in 6 states. Patients were 88.0% male, 56.6% Black, and 71.7% aged 16 to 36 years old, and 22.1% were admitted. A total of 2090 patients were matched on propensity for admission. Privately insured matched patients had 1.70 higher adjusted odds of admission and 95% confidence interval of 1.30 to 2.22, compared with uninsured after adjusting for patient and hospital characteristics. Conclusions: Insurance was associated with hospital admission for minor isolated extremity firearm injury.

A multidimensional approach to identifying high-performing trauma centers across the United States.

INTRODUCTION: The differentiators of centers performing at the highest level of quality and patient safety are likely both structural and cultural. We aimed to combine five indicators representing established domains of trauma quality and to identify and describe the structural characteristics of consistently performing centers. METHODS: Using American College of Surgeons Trauma Quality Improvement Program data from 2017 to 2020, we evaluated five quality measures across several care domains for adult patients in levels I and II trauma centers: (1) time to operating room for patients with abdominal gunshot wounds and shock, (2) proportion of patients receiving timely venous thromboembolism prophylaxis, (3) failure to rescue (death following a complication), (4) major hospital complications, and (5) mortality. Overall performance was summarized as a composite score incorporating all measures. Centers were ranked from highest to lowest performer. Principal component analysis showed the influence of each indicator on overall performance and supported the composite score approach. RESULTS: We identified 272 levels I and II centers, with 28 and 27 centers in the top and bottom 10%, respectively. Patients treated in high-performing centers had significant lower rates of death major complications and failure to rescue, compared with low-performing centers ( p < 0.001). The median time to operating room for gunshot wound was almost half that in high compared with low-performing centers, and rates of timely venous thromboembolism prophylaxis were over twofold greater ( p < 0.001). Top performing centers were more likely to be level I centers and cared for a higher number of severely injured patients per annum. Each indicator contributed meaningfully to the variation in scores and centers tended to perform consistently across most indicators. CONCLUSION: The combination of multiple indicators across dimensions of quality sets a higher standard for performance evaluation and allows the discrimination of centers based on structural elements, specifically level 1 status, and trauma center volume. LEVEL OF EVIDENCE: Therapeutic /Care Management; Level IV.

Pediatric Surgery Firearm Injury Collaborative Symposium.

Injury from a firearm is now the leading cause of death of children and youth under age 19 in the United States (U.S.) [1] and the incidence of these deaths continues to increase each year [2]. For every death from firearm violence, there are several young people who have been injured by a bullet but not killed. As pediatric surgeons, we are on the front lines of treating these young patients. We have the unforgettable memories of delivering the horrible news to parents in "quiet rooms." [3]. As these injuries fall within our scope of practice, it is incumbent on us as professionals to work to prevent these injuries, apply best practices and work for the best pathways to recovery for our patients who do survive. There is a diverse community of pediatric surgeons tackling this public health problem in a variety of ways [4]. In a pre-meeting symposium at the APSA 2023 Annual meeting, we brought together a community of pediatric surgeons working on this critical area. The following summarizes the presentations of the symposium, with topics including Risk Factors, Injury Prevention, Treatment, Public Initiatives, and National Collaborative Efforts. TYPE OF STUDY: Review Article, Proceedings of a Symposium. LEVEL OF EVIDENCE: 1 through 4 all presented.

Hospital variation in adoption of balanced transfusion practices among injured patients requiring blood transfusions.

BACKGROUND: This study sought to measure hospital variability in adoption of balanced transfusion following the Pragmatic, Randomized Optimal Platelet and Plasma Ratios (PROPPR) guidelines. We hypothesized hospital adoption rates of balanced transfusion would be low, and vary significantly among hospitals after controlling for patient, injury and hospital characteristics. STUDY DESIGN AND METHODS: This was an observational cohort study of injured adult patients (≥16 years) in Trauma Quality Improvement Program hospitals 2016-2021. Inclusion criteria were hypotensive patients receiving one transfusion of packed red blood cells, fresh frozen plasma, platelets, or cryoprecipitate. Balanced transfusion was defined as ≥1 ratio of plasma to packed red blood cells or platelets to packed red blood cells or whole blood use at 4 hours. Hierarchical multivariable logistic regression quantified residual hospital-level variability in balanced transfusion rates after adjusting for patient and hospital characteristics. RESULTS: Among 172,457 injured patients who received transfusions, 30,386 (17.6%) underwent balanced transfusion. Patient-level balanced transfusion rates were 11% in 2016, rose to 14.0% in 2019, and jumped up once whole blood transfusions were measured to 24.0% in 2020 and to 25.9% in 2021. Approximately 26% of the variability in balanced transfusion rates was attributable to the hospital. Verified level I hospitals had a 2.09 increased adjusted odds of balanced transfusion (95% CI 1.88-2.21) compared to nonverified hospitals. University teaching status had a 1.29 increased adjusted odds of balanced transfusion (95% CI 1.08-1.54) compared with community hospitals. Overall, 150 (23.5%) hospitals were high outliers (high performing) in balanced transfusion adoption and 124 (19.4%) hospitals were low outliers. CONCLUSION: There was significant variability in hospital adoption of balanced transfusion.

Morbidity and Length of Stay After Injury Among People Experiencing Homelessness in North America.

Importance: Traumatic injury is a leading cause of hospitalization among people experiencing homelessness. However, hospital course among this population is unknown. Objective: To evaluate whether homelessness was associated with increased morbidity and length of stay (LOS) after hospitalization for traumatic injury and whether associations between homelessness and LOS were moderated by age and/or Injury Severity Score (ISS). Design, Setting, and Participants: This retrospective cohort study of the American College of Surgeons Trauma Quality Programs (TQP) included patients 18 years or older who were hospitalized after an injury and discharged alive from 787 hospitals in North America from January 1, 2017, to December 31, 2018. People experiencing homelessness were propensity matched to housed patients for hospital, sex, insurance type, comorbidity, injury mechanism type, injury body region, and Glasgow Coma Scale score. Data were analyzed from February 1, 2022, to May 31, 2023. Exposures: People experiencing homelessness were identified using the TQP's alternate home residence variable. Main Outcomes and Measures: Morbidity, hemorrhage control surgery, and intensive care unit (ICU) admission were assessed. Associations between homelessness and LOS (in days) were tested with hierarchical multivariable negative bionomial regression. Moderation effects of age and ISS on the association between homelessness and LOS were evaluated with interaction terms. Results: Of 1 441 982 patients (mean [SD] age, 55.1 [21.1] years; (822 491 [57.0%] men, 619 337 [43.0%] women, and 154 [0.01%] missing), 9065 (0.6%) were people experiencing homelessness. Unmatched people experiencing homelessness demonstrated higher rates of morbidity (221 [2.4%] vs 25 134 [1.8%]; P < .001), hemorrhage control surgery (289 [3.2%] vs 20 331 [1.4%]; P < .001), and ICU admission (2353 [26.0%] vs 307 714 [21.5%]; P < .001) compared with housed patients. The matched cohort comprised 8665 pairs at 378 hospitals. Differences in rates of morbidity, hemorrhage control surgery, and ICU admission between people experiencing homelessness and matched housed patients were not statistically significant. The median unadjusted LOS was 5 (IQR, 3-10) days among people experiencing homelessness and 4 (IQR, 2-8) days among matched housed patients (P < .001). People experiencing homelessness experienced a 22.1% longer adjusted LOS (incident rate ratio [IRR], 1.22 [95% CI, 1.19-1.25]). The greatest increase in adjusted LOS was observed among people experiencing homelessness who were 65 years or older (IRR, 1.42 [95% CI, 1.32-1.54]). People experiencing homelessness with minor injury (ISS, 1-8) had the greatest relative increase in adjusted LOS (IRR, 1.30 [95% CI, 1.25-1.35]) compared with people experiencing homelessness with severe injury (ISS ≥16; IRR, 1.14 [95% CI, 1.09-1.20]). Conclusions and Relevance: The findings of this cohort study suggest that challenges in providing safe discharge to people experiencing homelessness after injury may lead to prolonged LOS. These findings underscore the need to reduce disparities in trauma outcomes and improve hospital resource use among people experiencing homelessness.

Patient and Hospital Characteristics Associated With Delayed Diagnosis of Appendicitis.

Importance: Racial disparities in timely diagnosis and treatment of surgical conditions exist; however, it is poorly understood whether there are hospital structural measures or patient-level characteristics that modify this phenomenon. Objective: To assess whether patient race and ethnicity are associated with delayed appendicitis diagnosis and postoperative 30-day hospital use and whether there are patient- or systems-level factors that modify this association. Design, Setting, and Participants: This population-based, retrospective cohort study used data from the Healthcare Cost and Utilization Project's state inpatient and emergency department (ED) databases from 4 states (Florida, Maryland, New York, and Wisconsin) for patients aged 18 to 64 years who underwent appendectomy from January 7, 2016, to December 1, 2017. Data were analyzed from January 1, 2016, to December 31, 2017. Exposure: Delayed diagnosis of appendicitis, defined as an initial ED presentation with an abdominal diagnosis other than appendicitis followed by re-presentation within a week for appendectomy. Main Outcomes and Measures: A mixed-effects multivariable Poisson regression model was used to estimate the association of delayed diagnosis of appendicitis with race and ethnicity while controlling for patient and hospital variables. A second mixed-effects multivariable Poisson regression model quantified the association of delayed diagnosis of appendicitis with postoperative 30-day hospital use. Results: Of 80 312 patients who received an appendectomy during the study period (median age, 38 years [IQR, 27-50 years]; 50.8% female), 2013 (2.5%) experienced delayed diagnosis. In the entire cohort, 2.9% of patients were Asian or Pacific Islander, 18.8% were Hispanic, 10.9% were non-Hispanic Black, 60.8% were non-Hispanic White, and 6.6% were other race and ethnicity; most were privately insured (60.2%). Non-Hispanic Black patients had a 1.41 (95% CI, 1.21-1.63) times higher adjusted rate of delayed diagnosis compared with non-Hispanic White patients. Patients at hospitals with a more than 50% Black or Hispanic population had a 0.73 (95% CI, 0.59-0.91) decreased adjusted rate of delayed appendicitis diagnosis compared with hospitals with a less than 25% Black or Hispanic population. Conversely, patients at hospitals with more than 50% of discharges of Medicaid patients had a 3.51 (95% CI, 1.69-7.28) higher adjusted rate of delayed diagnosis compared with hospitals with less than 10% of discharges of Medicaid patients. Additional factors associated with delayed diagnosis included female sex, higher levels of patient comorbidity, and living in a low-income zip code. Delayed diagnosis was associated with a 1.38 (95% CI, 1.36-1.61) increased adjusted rate of postoperative 30-day hospital use. Conclusions and Relevance: In this cohort study, non-Hispanic Black patients had higher rates of delayed appendicitis diagnosis and 30-day hospital use than White patients. Patients presenting to hospitals with a greater than 50% Black and Hispanic population were less likely to experience delayed diagnosis, suggesting that seeking care at a hospital that serves a diverse patient population may help mitigate the increased rate of delayed diagnosis observed for non-Hispanic Black patients.

The gap between hospital-based violence intervention services and client needs: A systematic review.

BACKGROUND: Survivors of intentional interpersonal violence face social challenges related to social determinants of health that led to their initial injury. Hospital-based violence intervention programs reduce reinjury. It is unclear how well they meet clients' reported needs. This systematic review aimed to quantify how well hospital-based violence intervention program services addressed clients' reported needs. METHODS: Medline, The Cochrane Library, CINAHL Plus with Full Text, and PsycInfo were queried for studies addressing hospital-based violence intervention programs services and intentional injury survivors' needs in the United States. Case reports, reviews, editorials, theses, and studies focusing on pediatric patients, victims of intimate partner violence, or sexual assault were excluded. Data extracted included program structure, hospital-based violence intervention program services, and client needs assessments before and after receiving hospital-based violence intervention program services. RESULTS: Of the 3,339 citations identified, 13 articles were selected for inclusion. Hospital-based violence intervention programs clients' most reported needs included mental health (10 studies), employment (7), and education (5) before receiving hospital-based violence intervention programs services. Only 4 studies conducted quantitative client needs assessments before and after receiving hospital-based violence intervention program services. All 4 studies were able to meet at least 50% of each of the clients' reported needs. The success rate depended on the need and program location: success in meeting mental health needs ranged from 65% to 90% of clients. Conversely, time-intensive long-term needs were least met, including employment 60% to 86% of clients, education 47% to 73%, and housing 50% to 71%. CONCLUSION: Few hospital-based violence intervention programs studies considered clients' reported needs. Employment, education, and housing must be a stronger focus of hospital-based violence intervention programs.

How does Injury Severity Score derived from International Classification of Diseases Programs for Injury Categorization using International Classification of Diseases, Tenth Revision, Clinical Modification codes perform compared with Injury Severity Score derived from Trauma Quality Improvement Program?

BACKGROUND: Injury Severity Score (ISS) is a measurement of injury severity based on the Abbreviated Injury Scale. Because of the difficulty and expense of Abbreviated Injury Scale coding, there have been recent efforts in mapping ISS from administrative International Classification of Diseases ( ICD ) codes instead. Specifically, the open source and freely available International Classification of Diseases Programs for Injury Categorization (ICDPIC) in R (Foundation for Statistical Computing, Vienna, Austria) converts International Classification of Diseases, Ninth Revision, codes to ISS. This study aims to compare ICDPIC calculations versus manually derived Trauma Quality Improvement Program (TQIP) calculations for International Classification of Diseases, Tenth Revision ( ICD-10 ), codes. Moderate concordance was chosen as the hypothetical relationship because of previous work by both Fleischman et al. ( J Trauma Nurs. 2017;24(1):4-14) who found moderate to substantial concordance between ICDPIC and ISS and Di Bartolomeo et al. ( Scand J Trauma Resusc Emerg Med. 2010;18(1):17) who found none to slight concordance. Given these very different findings, we thought it reasonable to predict moderate concordance with the use of more detailed ICD-10 codes. METHODS: This was an observational cohort study of 1,040,728 encounters in the TQIP registry for the year 2018. International Classification of Diseases Programs for Injury Categorization in R was used to derive ISS from the ICD-10 codes in the registry. The resulting scores were compared with the manually derived ISS in TQIP. RESULTS: The median difference between ISS calculated by ICDPIC-2021 using ICD-10, Clinical Modification (ISS-ICDPIC), and manually derived ISS was -3 (95% confidence interval, -5 to 0), while the mean difference was -2.09 (95% confidence interval, -2.10 to -2.07). There was substantial concordance between ISS-ICDPIC and manually derived ISS ( κ = 0.66). The ISS-ICDPIC was a better predictor of mortality (area under the curve, 0.853 vs. 0.836) but a worse predictor of intensive care unit admission (area under the curve, 0.741 vs. 0.757) and hospital stay ≥10 days (AUC, 0.701 vs. 0.743). The ICDPIC has substantial concordance with TQIP for the firearm ( κ = 0.69), motor vehicle trauma ( κ = 0.71), and pedestrian ( κ = 0.73) injury mechanisms. CONCLUSION: When TQIP data are unavailable, ICDPIC remains a valid way to calculate ISS after transition to ICD-10 codes. The ISS-ICDPIC performs well in predicting a number of outcomes of interest but is best served as a predictor of mortality. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level III.

Hospital variability in adoption of alcohol and drug screening in adult trauma patients.

BACKGROUND: Despite recommendations to screen all injured patients for substance use, single-center studies have reported underscreening. This study sought to determine if there was significant practice variability in adoption of alcohol and drug screening of injured patients among hospitals participating in the Trauma Quality Improvement Program. METHODS: This was a retrospective observational cross-sectional study of trauma patients 18 years or older in Trauma Quality Improvement Program 2017-2018. Hierarchical multivariable logistic regression modeled the odds of screening for alcohol and drugs via blood/urine test while controlling for patient and hospital variables. We identified statistically significant high and low-screening hospitals based on hospitals' estimated random intercepts and associated confidence intervals (CIs). RESULTS: Of 1,282,111 patients at 744 hospitals, 619,423 (48.3%) were screened for alcohol, and 388,732 (30.3%) were screened for drugs. Hospital-level alcohol screening rates ranged from 0.8% to 99.7%, with a mean rate of 42.4% (SD, 25.1%). Hospital-level drug screening rates ranged from 0.2% to 99.9% (mean, 27.1%; SD, 20.2%). A total of 37.1% (95% CI, 34.7-39.6%) of variance in alcohol screening and 31.5% (95% CI, 29.2-33.9%) of variance in drug screening were at the hospital level. Level I/II trauma centers had higher adjusted odds of alcohol screening (adjusted odds ratio [aOR], 1.31; 95% CI, 1.22-1.41) and drug screening (aOR, 1.16; 95% CI, 1.08-1.25) than Level III and nontrauma centers. We found 297 low-screening and 307 high-screening hospitals in alcohol after adjusting for patient and hospital variables. There were 298 low-screening and 298 high-screening hospitals for drugs. CONCLUSION: Overall rates of recommended alcohol and drug screening of injured patients were low and varied significantly between hospitals. These results underscore an important opportunity to improve the care of injured patients and reduce rates of substance use and trauma recidivism. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level III.
