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.

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.

A multi-dimensional 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 ACS-TQIP data from 2017-2020, we evaluated five quality measures across several care domains for adult patients in level I and II trauma centers; 1) time to operating room (OR) for patients with abdominal gunshot wounds (GSW) and shock, 2) proportion of patients receiving timely venous thromboembolism (VTE) 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 (PCA) showed the influence of each indicator on overall performance and supported the composite score approach. RESULTS: We identified 272 level 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 to low performing centers (p < 0.001). The median time to OR for GSW was almost half that in high compared to low performing centers, and rates of timely VTE prophylaxis were over two-fold 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. CONCLUSIONS: 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: Prognostic and Epidemiological, III.

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.

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.

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.

Years of Life Lost to Firearm Suicide Among Young People in the US.

This cross-sectional study examines years of life lost among the top 3 causes of death and compares firearm suicide with other methods of suicide among individuals aged 10 to 24 years in the US.

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.

Injury Patterns and Hospital Admission After Trauma Among People Experiencing Homelessness.

Importance: Traumatic injury is a major cause of morbidity for people experiencing homelessness (PEH). However, injury patterns and subsequent hospitalization among PEH have not been studied on a national scale. Objective: To evaluate whether differences in mechanisms of injury exist between PEH and housed trauma patients in North America and whether the lack of housing is associated with increased adjusted odds of hospital admission. Design, Setting, and Participants: This was a retrospective observational cohort study of participants in the 2017 to 2018 American College of Surgeons' Trauma Quality Improvement Program. Hospitals across the US and Canada were queried. Participants were patients aged 18 years or older presenting to an emergency department after injury. Data were analyzed from December 2021 to November 2022. Exposures: PEH were identified using the Trauma Quality Improvement Program's alternate home residence variable. Main Outcomes and Measures: The primary outcome was hospital admission. Subgroup analysis was used to compared PEH with low-income housed patients (defined by Medicaid enrollment). Results: A total of 1 738 992 patients (mean [SD] age, 53.6 [21.2] years; 712 120 [41.0%] female; 97 910 [5.9%] Hispanic, 227 638 [13.7%] non-Hispanic Black, and 1 157 950 [69.6%] non-Hispanic White) presented to 790 hospitals with trauma, including 12 266 PEH (0.7%) and 1 726 726 housed patients (99.3%). Compared with housed patients, PEH were younger (mean [SD] age, 45.2 [13.6] years vs 53.7 [21.3] years), more often male (10 343 patients [84.3%] vs 1 016 310 patients [58.9%]), and had higher rates of behavioral comorbidity (2884 patients [23.5%] vs 191 425 patients [11.1%]). PEH sustained different injury patterns, including higher proportions of injuries due to assault (4417 patients [36.0%] vs 165 666 patients [9.6%]), pedestrian-strike (1891 patients [15.4%] vs 55 533 patients [3.2%]), and head injury (8041 patients [65.6%] vs 851 823 patients [49.3%]), compared with housed patients. On multivariable analysis, PEH experienced increased adjusted odds of hospitalization (adjusted odds ratio [aOR], 1.33; 95% CI, 1.24-1.43) compared with housed patients. The association of lacking housing with hospital admission persisted on subgroup comparison of PEH with low-income housed patients (aOR, 1.10; 95% CI, 1.03-1.19). Conclusions and Relevance: Injured PEH had significantly greater adjusted odds of hospital admission. These findings suggest that tailored programs for PEH are needed to prevent their injury patterns and facilitate safe discharge after injury.

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.

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.

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.

Language of violence: Do words matter more than we think?

Firearm violence is a leading cause of morbidity and mortality among young adults. Identification of intervention targets is crucial to developing and implementing effective prevention efforts. Hospital Violence Intervention Programs (HVIPs) have used a multiprong social care approach to mediate the cycle of interpersonal violence. One struggle continually encountered is how to change the conversation around the future. Speech patterns have been associated with health outcomes and overall behavior modification. During violence prevention efforts, young victims of violence say things such as 'I'm living on borrowed time' and 'why should I worry about getting an education when I'll likely die soon anyway?' Such speech patterns may contribute to the cycle of violence and increase the likelihood of reinjury. Presented is a narrative review of the impact language has on health outcomes and how psychotherapy may be able to change thought patterns, alter language structure, and ultimately reduce risk of reinjury. The biopsychosocial model of health posits that a person's health is dictated by a combination of biological, psychological, and social factors. By understanding that language exists in the personal context, it can serve as both an indicator and a tool for targeted interventions. Cognitive-behavioral therapy (CBT) works by retraining thought and speech patterns to affect change in emotion, physiology, and behavior. It is proposed here that CBT could be used in the HVIPs' multidisciplinary case management model by involving trained psychotherapists. Language is an important indicator of a patient's psychological state and approach to life-changing decisions. As such, language alteration through CBT could potentially be used as a novel method of injury prevention. This concept has not before been explored in this setting and may be an effective supplement to HVIPs' success.

National evaluation of the association between stay-at-home orders on mechanism of injury and trauma admission volume.

BACKGROUND: The COVID-19 pandemic had numerous negative effects on the US healthcare system. Many states implemented stay-at-home (SAH) orders to slow COVID-19 virus transmission. We measured the association between SAH orders on the injury mechanism type and volume of trauma center admissions during the first wave of the COVID-19 pandemic. METHODS: All trauma patients aged 16 years and older who were treated at the American College of Surgeons Trauma Quality Improvement Program participating centers from January 2018-September 2020. Weekly trauma patient volume, patient demographics, and injury characteristics were compared across the corresponding SAH time periods from each year. Patient volume was modeled using harmonic regression with a random hospital effect. RESULTS: There were 166,773 patients admitted in 2020 after a SAH order and an average of 160,962 patients were treated over the corresponding periods in 2018-2019 in 474 centers. Patients presenting with a pre-existing condition of alcohol misuse increased (13,611 (8.3%) vs. 10,440 (6.6%), p <0.001). Assault injuries increased (19,056 (11.4%) vs. 15,605 (9.8%)) and firearm-related injuries (14,246 (8.5%) vs. 10,316 (6.4%)), p<0.001. Firearm-specific assault injuries increased (10,748 (75.5%) vs. 7,600 (74.0%)) as did firearm-specific unintentional injuries (1,318 (9.3%) vs. 830 (8.1%), p<0.001. In the month preceding the SAH orders, trauma center admissions decreased. Within a week of SAH implementation, hospital admissions increased (p<0.001) until a plateau occurred 10 weeks later above predicted levels. On regional sub-analysis, admission volume remained significantly elevated for the Midwest during weeks 11-25 after SAH order implementation, (p<0.001).

Nine years of pediatric gunshot wounds: A descriptive analysis.

Pediatric firearm violence carries significant morbidity and mortality. Studies targeting children ≤14 years are limited. Our goal was to study the distribution and determinants of GSWs in the pediatric population. We performed a retrospective review of children ≤14 years presenting with GSWs at this level 1 trauma center. This cohort was split into younger children, 0-12 years, and older children, 13-14 years. Summary and bivariate statistics were calculated using Stata v10. 142 patients (68.3% black, 76.7% male) were identified. Injuries more often occurred at home (39.6%) by family or friends (60.7%). Older children often suffered handgun injuries (85.5%) and more often were sent immediately to the OR on presentation (29.2%). Younger children more often suffered from air-gun (50%) and pistols (40%). Younger children more commonly had blood transfusions (9.4%) compared to exploratory laparotomy in older children (13.5%). The most common disposition from the ED was home (36.2%). Descriptive data entailing incident specifics such as time of injury and CPS involvement were frequently missing in the healthcare record. Older children were more likely to be injured by strangers, have longer lengths of stay especially associated with surgical operations, and have a disposition of immediate arrest compared to their younger cohort. Consequently, this group may benefit from interventions typically aimed at older patients such as violence intervention programs. When available, differences in demographics and outcomes were identified which could shape novel prevention strategies for firearm injury.

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.

Sex-Based Disparities in Timeliness of Trauma Care and Discharge Disposition.

Importance: Differences in time to diagnostic and therapeutic measures can contribute to disparities in outcomes. However, whether there is an association of timeliness by sex for trauma patients is unknown. Objective: To investigate whether sex-based differences in time to definitive interventions exist for trauma patients in the US and whether these differences are associated with outcomes. Design, Setting, and Participants: This was a retrospective cohort study conducted from July 2020 to July 2021, using the 2013 to 2016 Trauma Quality Improvement Program (TQIP) databases from level I to III trauma centers in the US. Patients 18 years or older with an Injury Severity Score (ISS) greater than 15 and who carried diagnoses of traumatic brain injury, intra-abdominal injury, pelvic fracture, femur fracture, and spinal injury as a result of their trauma were included in the study. Data were analyzed from July 2020 to July 2021. Main Outcomes and Measures: Primary outcomes assessed timeliness to interventions, using Wilcoxon signed rank and χ2 tests. Secondary outcomes included location of discharge after injury, using propensity score-matched generalized estimating equations modeling. Results: Of the 28 332 patients included, 20 002 (70.6%) were male patients (mean [SD] age, 43.3 [18.2] years) and 8330 (29.4%) were female patients (mean [SD] age, 48.5 [21.1] years), with significantly different distributions of ISS scores (ISS score 16-24: male patient, 10 622 [53.1%]; female patient, 4684 [56.2%]; ISS score 41-74: male patient, 2052 [10.3%]; female patient, 852 [10.2%]). Male patients more frequently had abdominal (4257 [21.3%] vs 1268 [15.2%]) and spinal cord (3989 [20.0%] vs 1274 [15.3%]) injuries, whereas female patients experienced greater proportions of femur (3670 [44.0%] vs 8422 [42.1%]) and pelvic (3970 [47.6%] vs 6963 [34.8%]) fractures. Female patients experienced significantly longer emergency department length of stay (median [IQR], 184 [92-314] minutes vs 172 [86-289] minutes; P < .001), longer time in pretriage (median [IQR], 52 [36-80] minutes vs 49 [34-77] minutes; P < .001), and increased likelihood of discharge to nursing or long-term care facilities instead of home after matching by age, ISS, mechanism, and injury type (male patient:female patient, odds ratio, 0.72; 95% CI, 0.67-0.78). Conclusions and Relevance: Results of this cohort study suggest that female trauma patients experienced slightly longer delays in trauma care and had a higher likelihood of discharge to long-term care facilities than their male counterparts.
