Evaluating Firearm Violence After New Jersey's Cash Bail Reform.

Importance: Reducing the pretrial detention population has been a cornerstone of movements to end mass incarceration. Across many US cities, there are ongoing public debates on policies that would end pretrial detention due to the inability to afford bail, with some raising concerns that doing so would increase community violence. Objective: To evaluate changes in firearm violence after New Jersey's 2017 bail reform policy that eliminated financial barriers to avoiding pretrial detention. Design, Setting, and Participants: This case-control study used synthetic control methods to examine changes in firearm mortality and combined fatal and nonfatal shootings in New Jersey (2014-2019). New Jersey was chosen because it was one of the first states to systematically implement cash bail reform. Outcomes in New Jersey were compared with a weighted combination of 36 states that did not implement any kind of reform to pretrial detention during the study period. Data were analyzed from April 2023 to March 2024. Exposure: Implementation of New Jersey's cash bail reform law in 2017. Main Outcomes and Measures: Quarterly rates of fatal and nonfatal firearm assault injuries and firearm self-harm injuries per 100 000 people. Results: Although New Jersey's pretrial detention population dramatically decreased under bail reform, the study did not find evidence of increases in overall firearm mortality (average treatment effect on the treated, -0.26 deaths per 100 000) or gun violence (average treatment effect on the treated, -0.24 deaths per 100 000), or within racialized groups during the postpolicy period. Conclusions and Relevance: Incarceration and gun violence are major public health problems impacting racially and economically marginalized groups. Cash bail reform may be an important tool for reducing pretrial detention and advancing health equity without exacerbating community violence.

Firearm-Related Injuries and the US Opioid and Other Substance Use Epidemic: A Nationwide Evaluation of Emergency Department Encounters.

INTRODUCTION: There has been a sharp climb in the Unites States' death rate among opioid and other substance abuse patients, as well as an increased prevalence in gun violence. We aimed to investigate the association between substance abuse and gun violence in a national sample of patients presenting to US emergency departments (EDs). METHODS: We queried the 2018-2019 Nationwide Emergency Department Sample for patients ≥18 years with substance abuse disorders (opioid and other) using International Classification of Diseases, 10th Revision, Clinical Modification codes. Within this sample, we analyzed characteristics and outcomes of patients with firearm-related injuries. The primary outcome was mortality; secondary outcomes were ED charges and length of stay. RESULTS: Among the 25.2 million substance use disorder (SUD) patients in our analysis, 35,306 (0.14%) had a firearm-related diagnosis. Compared to other SUD patients, firearm-SUD patients were younger (33.3 versus 44.7 years, P < 0.001), primarily male (88.6% versus 54.2%, P < 0.001), of lower-income status (0-25th percentile income: 56.4% versus 40.5%, P < 0.001), and more likely to be insured by Medicaid or self-pay (71.6% versus 53.2%, P < 0.001). Firearm-SUD patients had higher mortality (1.4% versus 0.4%, P < 0.001), longer lengths of stay (6.5 versus 4.9 days, P < 0.001), and higher ED charges ($9269 versus $5,164, P < 0.001). Firearm-SUD patients had a 60.3% rate of psychiatric diagnoses. Firearm-SUD patients had 5.5 times greater odds of mortality in adjusted analyses (adjusted odds ratio: 5.5, P < 0.001). CONCLUSIONS: Opioid-substance abuse patients with firearm injuries have higher mortality rates and costs among these groups, with limited discharge to postacute care resources. All these factors together point to the urgent need for improved screening and treatment for this vulnerable group of patients.

Lactic acid levels are associated with morbidity, length of stay, and total treatment costs in urban trauma patients with lower extremity long bone fractures.

INTRODUCTION: Lactic acid is well studied in the trauma population and is frequently used as a laboratory indicator that correlates with resuscitation status and has thus been associated with patient outcomes. There is limited literature that assesses the association of initial lactic acid with post-operative morbidity and hospitalization costs in the orthopedic literature. The purpose of this study was to assess the association of lactic acid levels and alcohol levels post-operative morbidity, length of stay and admission costs in a cohort of operative lower extremity long bone fractures, and to compare these effects in the ballistic and blunt trauma sub-population. METHODS: Patients presenting as trauma activations who underwent tibial and/or femoral fixation at a single institution from May 2018 to August 2020 were divided based on initial lactate level into normal, (< 2.5) intermediate (2.5-4.0), and high (> 4.0). Mechanism of trauma (blunt vs. ballistic) was also stratified for analysis. Data on other injuries, surgical timing, level of care, direct hospitalization costs, length of stay, and discharge disposition were collected from the electronic medical record. The primary outcome assessed was post-operative morbidity defined as in-hospital mortality or unanticipated escalation of care. Secondary outcomes included hospital costs, lengths of stay, and discharge disposition. Data were analyzed using ANOVA and multivariate regression. RESULTS: A total of 401 patients met inclusions criteria. Average age was 34.1 ± 13.0 years old, with patients remaining hospitalized for 8.8 ± 9.5 days, and 35.2% requiring ICU care during their hospitalization. Patients in the ballistic cohort were younger, had fewer other injuries and had higher lactate levels (4.0 ± 2.4) than in the blunt trauma cohort (3.4 ± 1.9) (p = 0.004). On multivariate regression, higher lactate was associated with post-operative morbidity (p = 0.015), as was age (p < 0.001) and BMI (p = 0.033). ISS, ballistic versus blunt injury mechanism, and other included laboratory markers were not. Lactate was also associated with longer lengths of stay, and higher associated direct hospitalization cost (p < 0.001) and lower rates of home disposition (p = 0.008). CONCLUSION: High initial lactate levels are independently associated with post-operative morbidity as well as higher direct hospitalization costs and longer lengths of stay in orthopedic trauma patients who underwent fixation for fractures of the lower extremity long bones. Ballistic trauma patients had significantly higher lactate levels compared to the blunt cohort, and lactate was not independently associated with increased rates of post-operative morbidity in the ballistic cohort alone. LEVEL OF EVIDENCE: III.

The Medical Costs of Firearm Injuries in the United States: A Systematic Review.

BACKGROUND: Firearm injury poses a significant public health burden in the United States. OBJECTIVES: The purpose of this systematic review was to provide a comprehensive accounting of the medical costs of firearm injuries in the United States. METHODS: A systematic literature review was conducted to identify studies published between January 1, 2000 and July 13, 2022 that reported medical costs of firearm injuries. A search of Embase, PubMed, and the Cochrane Library databases was performed by a medical librarian. The National Institutes of Health Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies was used to evaluate for risk of bias. Health care-related charges and costs per firearm injury were presented and trends were identified. RESULTS: Sixty-four studies were included in the analysis. Study sample sizes ranged from 18 to 868,483 patients. Reported costs per injury ranged from $261 to $529,609. The median cost reported was $27,820 (interquartile range [IQR] $15,133-$40,124) and median charge reported was $53,832 (IQR $38,890-$98,632). Studies that divided initial hospitalization costs and follow-up medical costs identified that initial hospitalization accounts for about 60% of total costs. CONCLUSIONS: We found a significant volume of literature about the medical costs of firearm injury, which identified a highly heterogeneous cost burden. A significant amount of cost burden occurs after the index hospitalization, which is the only cost reported in most studies. Limitations of this study include reporting bias that favors hospitalized patients as well as a large focus on hospital charges as measurements of cost identified in the literature.

Outcomes of Hospitalized Injured Suspects Sustaining Gunshot Wounds From Law Enforcement Action.

BACKGROUND: Although firearms are implicated in the majority of law enforcement intervention (LEI)-related deaths, scientific research is lacking. The present study sought to characterize clinical and financial outcomes between injured suspects and other gunshot wound (GSW) patients. STUDY DESIGN: The 2016-2020 National Inpatient Sample was queried for patients ≥16 years old admitted following GSW. Patients were categorized as injured suspects (ISs) if they were injured in LEI and non-IS otherwise. The primary outcome was in-hospital mortality with complications, hospitalization duration (LOS), and costs secondarily considered. Multivariable regression models were used to adjust for patient characteristics, injury burden using the Trauma Mortality Prediction Model (TMPM), and hospital factors. RESULTS: Of 143,125 hospitalizations, 1575 (1.10%) were IS. Compared to non-IS, ISs were less frequently Black (24.4% vs 54.3%) but had a higher proportion of psychiatric conditions (19.4% vs 6.4%) (P < .05). Although having a similar requirement for major operations and TMPM score, ISs more frequently underwent thoracic (11.4% vs 4.1%) and gastrointestinal operations (33.0% vs 25.7%) (P < .05). After adjustment, IS was associated with similar odds of mortality but was associated with greater odds of cardiac complications, respiratory failure, and need for intensive care. While LOS was similar, IS was associated with greater costs (ß: +$14,300, 95% CI: 6,200-22,400). CONCLUSIONS: Suspects injured during law enforcement intervention have similar in-hospital mortality but greater complication rates and costs. Through the quantification of the clinical and financial burden of IS, our findings may help inform further policy discussions regarding use of potentially lethal force in law enforcement intervention.

Financial burden of pediatric firearm-related injury admissions in the United States.

Pediatric firearm-related injuries pose a significant public health problem in the United States, yet the associated financial burden has not been well described. This is the first study examining national data on the cost of initial hospitalization for pediatric firearm-related injuries. In this retrospective review, the Healthcare Cost and Utilization Project Kids' Inpatient Database from the years 2003, 2006, 2009, and 2012 was used to identify all patients 18 years of age and under who were admitted with firearm-related injuries. We compared demographic and discharge-level data including injury severity score, hospital length of stay, income quartile, injury intent, and inflation-adjusted hospital costs across age groups (0-5, 6-9, 10-15, 16-18 years). There were approximately 4,753 pediatric firearm-related admissions each year, with a median hospitalization cost of $12,984 per patient. Annual initial hospitalization costs for pediatric firearm injuries were approximately $109 million during the study period. Pediatric firearm-related injuries predominately occured among older teenagers (74%, 16-18 years), males (89%), black individuals (55%), and those from the lowest income quartile (53%). We found significant cost variation based on patient race, income quartile, injury severity score, intent, hospital length of stay, disposition, and hospital region. Inflation-adjusted hospitalization costs have increased significantly over the study period (p < 0.001). Pediatric firearm-related injuries are a large financial burden to the United States healthcare system. There are significant variations in cost based on predictable factors like hospital length of stay and injury severity score; however, there are also substantial discrepancies based on hospital region, patient race, and income quartile that require further investigation.

National Trends in the Cost Burden of Pediatric Gunshot Wounds Across the United States.

OBJECTIVE: To characterize hospitalization costs attributable to gun-related injuries in children across the US. STUDY DESIGN: The 2005-2017 National Inpatient Sample was used to identify all pediatric admissions for gunshot wounds (GSW). Patients were stratified by International Classification of Diseases procedural codes for trauma-related operations. Annual trends in GSW hospitalizations and costs were analyzed with survey-weighted estimates. Multivariable regressions were used to identify factors associated with high-cost hospitalizations. RESULTS: During the study period, an estimated 36 283 pediatric patients were admitted for a GSW, with 43.1% undergoing an operative intervention during hospitalization. Admissions for pediatric firearm injuries decreased from 3246 in 2005 to 3185 in 2017 (NPtrend < .001). The median inflation-adjusted cost was $12 408 (IQR $6253-$24 585). Median costs rose significantly from $10 749 in 2005 to $16 157 in 2017 (P < .001). Compared with those who did not undergo surgical interventions, operative patients incurred increased median costs ($18 576 vs $8942, P < .001). Assault and self-harm injuries as well as several operations were independently associated with classification in the highest cost tertile. CONCLUSIONS: Admissions for pediatric firearm injuries were associated with a significant socioeconomic burden in the US, with increasing resource use over time. Pediatric gun violence is a major public health crisis that warrants further research and advocacy to reduce its prevalence and social impact.

Penetrating Trauma Rapid Estimated Disability Scale: Assessing Facial Self-Inflicted Gunshot Wounds.

Objectives: Self-inflicted facial gunshot wounds (GSWs) result in complex but consistent injuries that are often survivable. We suggest a novel method for rapid stratification into groups that may be associated with hospital course and cost after self-inflicted facial GSWs. Methods: This is retrospective review of self-inflicted facial GSWs between January 1, 2009, and December 31, 2018, at a tertiary academic center. Patients were given a penetrating trauma rapid estimated disablity (PRED) score (1-4) based solely on radiologic imaging injury patterns. Clinicopathologic factors were then compared between groups. Results: There were 2 PRED 1 patients (15.1%), 8 PRED 2 patients (29.6%), 5 PRED 3 patients (18.5%), and 12 PRED 4 patients (44.4%). An increased PRED score was statistically associated with increasing mean days in intensive care unit (2.5 PRED 1, 4.2 PRED 2, 6 PRED 3, 11.6 PRED 4, p = 0.001), mean length of hospitalization (5.5 PRED 1, 13.1 PRED 2, 25.6 PRED 3, 39.8 PRED 4, p = 0.007), and mean cost ($) of hospitalization (22,000 PRED 1, 29,000 PRED 2, 37,000 PRED 3, 63,000 PRED 4, p = 0.01). Conclusions and Relevance: The PRED score for self-inflicted GSWs to the face is strongly associated with length of hospital stay and cost of hospitalization.

United States trends in healthcare charges for pediatric firearm injuries.

BACKGROUND: From 2009 to 2016, >21,000 children died and an estimated 118,000 suffered non-fatal injuries from firearms in the United States. Limited data is available on resource utilization by injury intent. We use hospital charges as a proxy for resource use and sought to: 1) estimate mean charges for initial ED and inpatient care for acute firearm injuries among children in the U.S.; 2) compare differences in charges by firearm injury intent among children; and 3) evaluate trends in charges for pediatric firearm injuries over time, including within intent subgroups. METHODS: In this repeated cross-sectional analysis of the 2009-2016 Nationwide Emergency Department Sample, we identified firearm injury cases among children aged ≤19 years using ICD-9-CM and ICD-10-CM external cause of injury codes (e-codes). Injury intent was categorized using e-codes as unintentional, assault-related, self-inflicted, or undetermined. Linear regressions utilizing survey weighting were used to examine associations between injury intent and healthcare charges, and to evaluate trends in mean charges over time. RESULTS: Among 21,951 unweighted cases representing 102,072 pediatric firearm-related injuries, mean age was 16.6 years, and a majority were male (88.2%) and publicly insured (51.5%). Injuries were 53.9% assault-related, 37.7% unintentional, 1.8% self-inflicted, and 6.7% undetermined. Self-inflicted injuries had higher mean charges ($98,988) than assault-related ($52,496) and unintentional ($28,618) injuries (p < 0.001). Self-inflicted injuries remained associated with higher mean charges relative to unintentional injuries, after adjusting for patient demographics, hospital characteristics, and injury severity (p = 0.015). Mean charges for assault-related injuries also remained significantly higher than charges for unintentional injuries in multivariable models (p < 0.001). After adjusting for inflation, mean charges for pediatric firearm-related injuries increased over time (p-trend = 0.018) and were 23.1% higher in 2016 versus 2009. Mean charges increased over time among unintentional injuries (p-trend = 0.002), but not among cases with assault-related or self-inflicted injuries. CONCLUSIONS: Self-inflicted and assault-related firearm injuries are associated with higher mean healthcare charges than unintentional firearm injuries among children. Mean charges for pediatric firearm injuries have also increased over time. These findings can help guide prevention interventions aimed at reducing the substantial burden of firearm injuries among children.

Prevalence and hospital charges from firearm injuries treated in US emergency departments from 2006 to 2016.

BACKGROUND: Age- and intent-related differences in the burden and costs of firearm injury treated in emergency departments are not well-documented. METHODS: We performed a serial cross-sectional study of the Healthcare Cost and Utilization Program Nationwide Emergency Department Survey from 2006 to 2016. We used International Classification of Diseases diagnoses codes revisions 9 and 10 to identify firearm injuries. We calculated survey-weighted counts, proportions, means, and rates and confidence intervals of national, age-specific (0-4, 5-9, 10-14, 15-17, 18-44, 45-64, 65-84, >84) and intent-specific (assault, unintentional, suicide, undetermined) emergency department discharges for firearm injuries. We used survey-weighted regression to assess temporal trends. RESULTS: There was a total of 868,483 (25.5 per 100,000) emergency department visits for firearm injuries from 2006 to 2016, and 7.8% died in the emergency department. Overall, firearm injury rates remained steady (P = .78). The largest burden was among those 25 to 44 years of age, but their rates remained stable (10.8 per 100,000). Overall assault injuries declined from 39.7% to 36.4%, and overall unintentional injuries increased from 46.4% to 54.7%. Legal-intervention injuries declined from 0.6 to 0.3 per 100,000. The charges (total $4,059,070,364, $369,006,396/year) increased across time in age and intent groups. The mean predicted charges increased from $1,922 to $3,348 in those alive versus $3,741 to $6,515 among those who died. CONCLUSION: Interventions and programs to manage the consequences of firearm injury in persons who live with ongoing morbidity and economic burden are warranted.

Increases in Actual Health Care Costs and Claims After Firearm Injury.

BACKGROUND: The incidence of firearm injury and death in the United States is increasing. Although the health care-related effect of firearm injury is estimated to be high, existing data are largely cross-sectional, do not include data on preinjury and postinjury health care visits and related costs, and use hospital charges rather than actual monetary payments. OBJECTIVE: To compare actual health care costs (that is, actual monetary payments) and utilizations within the 6 months before and after an incident (index) firearm injury. DESIGN: Before-after study. SETTING: Blue Cross Blue Shield plans of Illinois, Texas, Oklahoma, New Mexico, and Montana. PARTICIPANTS: Plan members continuously enrolled for at least 12 months before and after an index firearm injury sustained between 1 January 2015 and 31 December 2017. MEASUREMENTS: Eligible costs, out-of-pocket costs, and firearm injury-related International Classification of Diseases, Ninth or 10th Revision, codes. RESULTS: Total initial (emergency department [ED]) health care costs for persons with index firearm injuries who were discharged from the ED were $8 158 786 ($5686 per member). Total initial (hospital admission) costs for persons with index firearm injuries who required hospitalization were $41 255 916 ($70 644 per member). Compared with the 6 months before the index firearm injury, in the 6 months after, per-member costs increased by 347% (from $3984 to $17 806 per member) for those discharged from the ED and 2138% (from $4118 to $92 151 per member) for those who were hospitalized. The number of claims increased by 187% for patients discharged from the ED and 608% for those who were hospitalized. LIMITATION: Firearm injury intent was not specified because of misclassification concerns. CONCLUSION: In the 6 months after a firearm injury, patient-level health care visits and costs increased by 3 to 20 times compared with the 6 months prior. The burden of firearm injury on the health care system is large and quantifiable. PRIMARY FUNDING SOURCE: None.

Financial burden of orthopaedic gunshot-related injury management at a major trauma centre.

BACKGROUND: Violence and injuries are a significant global public health concern, and have a substantial emotional, physical and economic impact on society. In South Africa (SA), the Western Cape Injury Mortality Profile shows that homicides increased from 38 deaths per 100 000 in 2010 to 52 deaths per 100 000 in 2016. This increase is directly related to an increase in firearm-related homicides, which doubled from 2010 to 2016. Previous research estimated the average cost per gunshot wound (GSW)-related orthopaedic patient at USD2 940. GSW-related patient numbers as well as treatment costs have escalated exponentially over the past few years. OBJECTIVES: To calculate the financial costs involved in managing gunshot-related orthopaedic injuries both surgically and non-surgically at a tertiary centre in SA. METHODS: After ethics approval, a retrospective review of all GSW patients seen in the emergency unit at Tygerberg Hospital in 2017 was undertaken. Patient records yielded data on the following parameters: injury site and characteristics, imaging modalities, orthopaedic management, hospital admission and duration of hospitalisation, theatre episodes, orthopaedic implants and blood products administered. Cost analysis was performed using this information. RESULTS: A total of 389 patients (360 male and 29 female), average age (range, standard deviation) 28 (3 - 69, 9.50) years, were treated during the study period. Patient records identified a total of 449 orthopaedic injuries. A total of 187 patients were admitted, with 175 requiring surgical fixation. The conservatively calculated cost of managing this patient group was ZAR10 227 503. The average management cost per patient was ZAR26 292, with an average of ZAR46 670 per case requiring surgical management and ZAR8 810 for non-surgical cases (the average USD-ZAR exchange rate in 2017 was USD1-ZAR13.30). CONCLUSIONS: The total cost of managing 389 patients with gunshot-related orthopaedic injuries at a tertiary hospital was ZAR10 227 503. Improved understanding of these costs will help the healthcare system better prioritise orthopaedic trauma funding and training and highlights the urgent need for cost-saving measures, specifically primary prevention initiatives.

National Trends and Cost Burden of Surgically Treated Gunshot Wounds in the US.

BACKGROUND: Gun violence remains a major burden on the US healthcare system, with annual cost exceeding $170 billion. Literature on the national trends in cost and survival of gun violence victims requiring operative interventions is lacking. STUDY DESIGN: All adults admitted with a diagnosis of gunshot wound requiring operative intervention were identified using the 2005-2016 National Inpatient Sample. The ICD Injury Severity Score, a validated prediction tool, was used to quantify the extent of traumatic injuries. Survey-weighted methodology was used to provide national estimates. Hospitalizations exceeding the 66th percentile of annual cost were considered as high-cost tertile. Multivariable logistic regressions with stepwise forward selection were used to identify factors associated with mortality and high-cost tertile. RESULTS: During the study period, 262,098 admissions met inclusion criteria with a significant increase in annual frequency and decrease in ICD Injury Severity Scores. A decline in mortality (8.6% to 7.6%; parametric test of trend = 0.03) was accompanied by increasing mean cost ($25,900 to $33,000; nonparametric test of trend < 0.001). After adjusting for patient and hospital characteristics, head and neck (adjusted odds ratio 31.2; 95% CI, 11.0 to 88.4; p < 0.001), vascular operations (adjusted odds ratio 24.5; 95% CI, 19.2 to 31.1; p < 0.001), and gastrointestinal (adjusted odds ratio 27.8; 95% CI, 17.2 to 44.8; p < 0.001) were independently associated with high-cost tertile designation compared with patients who did not undergo these operations. CONCLUSIONS: During the past decade, the increase in gun violence and severity has resulted in higher cost. Operations involving selected surgical treatments incurred higher in-hospital cost. Given the profound economic and social impact of surgically treated gunshot wounds, policy and public health efforts to reduce gun violence are imperative.

Guns, scalpels, and sutures: The cost of gunshot wounds in children and adolescents.

BACKGROUND: Firearm injuries are the second leading cause of death among US children. While injury prevention has been shown to be effective for blunt mechanisms of injury, the rising incidence of accidental gunshot wounds, school shootings, and interpersonal gun violence suggests otherwise for firearm-related injuries. The purpose of the study is to describe the incidence, injury severity, and institutional costs of pediatric gun-related injuries in Colorado. METHODS: Pediatric patients (≤18 years), who sustained firearm injuries between 2008 and 2018, were identified from the trauma registries of three pediatric trauma centers in Colorado. Patients were stratified based on age: those younger than 14 years were defined as children and those 15 years to 18 years as adolescents. RESULTS: Our cohort (n = 308) was predominantly male (87%), with a median age of 14 years. The overall mortality rate was 11% (34/308), with significantly fewer children (5%) dying from their injuries when compared with adolescents (14%; p = 0.04). Sixty-five (21%) patients required blood product transfusions, with 23 (7.4%) patients receiving a massive transfusion. Overall, 52% (161/308) required a major operation, with 15% undergoing an exploratory laparotomy. One third (4/13) of the patients who had a thoracotomy in the emergency department survived to hospital discharge. Overall, 14.0% of patients had psychiatric follow-up at both 30 days and 1 year. The readmission rate for complications was 11.6% at 30 days and 14% at 1 year. The total cost of care for all pediatric firearm-related injuries was approximately US $26 million. CONCLUSION: The survivors of pediatric firearm injuries experience high operative and readmission rates, sustain long-term morbidities, and suffer from mental health sequelae. Combining these factors with the economic impact of these injuries highlights the immense burden of disease. This burden may be palliated by a multipronged approach, which includes the development and dissemination of injury prevention strategies and better follow-up care for these patients. LEVEL OF EVIDENCE: Epidemiological, Level III.

The cost of gunshot abdominal vascular injuries. Its impact on patient, family and hospital.

BACKGROUND: Violent trauma with penetrating injuries is a relevant public health issue. Penetrating abdominal wounds cause 90-95% of vascular injuries, which not only have high associated morbidity and lethality, but also involve high attention costs. Cost analysis in hospitals has become a topic of great interest, as it justifies changes in hospital organization and management. OBJECTIVE: Determine the cost of gunshot abdominal vascular injuries for the patient, his family and the hospital. MATERIAL AND METHODS: We drove an observational, descriptive, prospective and longitudinal study of patients with of gunshot abdominal vascular injuries admitted in the Mexican Red Cross Trauma Center in the Federal District from January 1st to October 31st, 2018. RESULTS: 8149 patients were admitted in the emergency department, 149 with a diagnosis of gunshot injury, of which 6 (0.07%) had abdominal vascular injury. The total cost of medical care these patients was on average $174,770.79 (median $132,999.50) per capita, amount that surpasses their annual income and implies an institutional absorption of expenditure up to 95.5%. CONCLUSIONS: Institutional investment on the attention of high-impact pathologies and the development of strategies that facilitate access to health services are a real and priority necessity.

ANTECEDENTES: El trauma violento con lesiones penetrantes es un problema de salud pública relevante. Las heridas penetrantes abdominales causan el 90-95% de las lesiones vasculares, las cuales tienen elevada morbilidad asociada y letalidad, e implican elevados costos de atención. El análisis de costos en los hospitales es de gran interés, pues permite justificar cambios en la organización y la gestión hospitalaria. OBJETIVO: Determinar el costo de las lesiones vasculares abdominales por proyectil de arma de fuego para el paciente, su familia y el hospital. MATERIAL Y MÉTODOS: Se llevó a cabo un estudio observacional, descriptivo, prospectivo y longitudinal de pacientes con lesiones vasculares abdominales por proyectil de arma de fuego que ingresaron en el Centro de Trauma de Cruz Roja Mexicana en Ciudad de México entre enero y octubre de 2018. RESULTADOS: Ingresaron 8149 pacientes, 149 con diagnóstico de herida por proyectil de arma de fuego, de los cuales el 0.07% tuvieron lesión vascular abdominal. El costo total de la atención médica fue en promedio de $174,770.79 (mediana $132,999.50) por persona, el cual supera el ingreso anual de esos pacientes e implica una absorción institucional del gasto de hasta el 95.5%. CONCLUSIONES: La inversión institucional en la atención de patologías con alto impacto y el desarrollo de estrategias para facilitar el acceso a servicios de salud son una necesidad prioritaria real.

Pediatric firearm injuries: Racial disparities and predictors of healthcare outcomes.

BACKGROUND/PURPOSE: The U.S. has an alarming rate of firearm injuries. Racial disparities among victims and predictors of outcomes are not well established. Our objective was to assess costs, length of stay (LOS), and inpatient mortality among nonfatal and fatal pediatric firearm injuries that required hospitalization. METHODS: Pediatric (≤18 years of age) hospitalizations with a firearm injury discharge diagnosis were identified from the national Kids' Inpatient Databases (KID) for 2006 through 2012. Firearm injury intent, weapon type, and hospitalization rates by racial groups were examined. Inpatient mortality, costs, and length of stay were examined using regression models. RESULTS: Of 15,211 hospitalizations, the majority of injuries were due to assault (60%) and the intentions of firearm injury differed by race (p < 0.001). The median cost per hospitalization was $10,159 (interquartile range: $5071 to $20,565), totaling more than a quarter of a billion dollars. On regression analysis, Black (OR: 0.41; CI: 0.30-0.55) and Hispanic (OR: 0.47; CI: 0.34-0.66) patients were less likely to die than White patients. CONCLUSION: Pediatric firearm injury circumstances and survival vary by race with Whites being more likely to experience unintentional injury and suicide, while Blacks and Hispanics are more likely to experience inflicted injury. LEVEL OF EVIDENCE: Level II. TYPE OF STUDY: Clinical Research Study.

Human and economic costs of pediatric firearm injury.

PURPOSE: Pediatric firearm injury is a national crisis that inflicts significant trauma. No studies have captured risk factors for readmissions after firearm injury, including cost analysis. METHODS: Nationwide Readmissions Database (2010-2014) was queried for patients <18 years admitted after acute firearm injury. Outcomes included mortality, length of stay, hospital costs, and readmission rates (30-day and 1-year). Multivariable logistic regression identified risk factors, significance set at p < 0.05. RESULTS: There were 13,596 children admitted for firearm injury. Mortality rate was 6% (n = 797). Self-inflicted injury was the most lethal (37%, n = 218) followed by unintentional (5%, n = 186), and assault (4%, n = 340), all p < 0.01. Readmission rates at 30 days and 1-year were 6% (12% to different hospital) and 12% (19% to different hospital), respectively. Medicaid patients were more frequently readmitted to the index hospital, whereas self-pay and/or high income were readmitted to a different hospital. The total hospitalizations cost was over $382 million, with $5.4 million due to readmission to a different hospital. CONCLUSION: While guns cause significant morbidity, disability, and premature mortality in children, they also have a substantial economic impact. This study quantifies the previously unreported national burden of readmission costs and discontinuity of care for this preventable public health crisis.

Air Guns: A Contemporary Review of Injuries at Six Pediatric Level I Trauma Centers.

BACKGROUND: Studies spanning the last three decades demonstrated the injury causing capability of air gun (AG) projectiles. Recent studies have suggested the impact and incidence of these injuries may be declining because of edcational efforts. We hypothesize that injuries in the pediatric population resulting from AGs remain a significant health concern. METHODS: A retrospective review (1/1/2007 to 12/31/2016), of AG-injured children < 19 years old, was performed across six level I Pediatric Trauma Centers, part of the ATOMAC research consortium. AG injuries were defined as injuries sustained by ball-bearing or pellet air-powered guns. Paint ball and soft foam AGs were excluded. Following institutional review board approval, patients were identified by ICD code from the trauma registry. Included were demographic data, injury severity scores, length of stay (LOS), outcome at discharge, and overall cost of admission. Descriptive statistics and parametric tests were employed. RESULTS: A total of 499 patients sustained injuries. Mean age 9.5 (±4.0) y; 81% of victims were male; all survived to hospital discharge. 30% (n = 151) required operative intervention. Hospital LOS was 2.3 (±2.2) d; with mean cost of $23,756 (±$34,441). Injury severity score mean of 3.7 (±4.6) on admission. Over 40% of the injuries to the head/thorax that were severe (AIS ≥ 3) required operative intervention (P < 0.001). CONCLUSIONS: AG injuries to the head or thorax seen at trauma centers were likely to require operative management. While no fatalities occurred, the cost was substantial. This study demonstrates pediatric injuries resulting from AG projectiles remain a significant health concern.

The Effect of Opioid Dependence on Firearm Injury Treatment Outcomes: A Nationwide Analysis.

BACKGROUND: Both the opioid and gun violence epidemics are recurrent public health issues in the United States. We sought to determine the effect of opioid dependence on gunshot injury treatment outcomes. MATERIALS AND METHODS: Using the 2016 National Readmission Database, patients were included if they had a principal diagnosis of firearm injury. Opioid dependence was identified using appropriate International Classification of Diseases, 10th Revision, Clinical Modification codes. The primary outcome was 30-day all-cause readmission. Secondary outcomes were in-hospital and 1-year mortality, resource utilization, and most common reasons for admission and readmission. Confounders were adjusted for using multivariate regression analysis. RESULTS: A total of 31,303 patients were included, 695 of whom were opioid dependent. Opioid-dependent patients were more likely to be young (35.1 y, range: 33.4-36.7 y) and male (89.9%) compared with patients without opioid dependence. Opioid dependence was associated with higher 30-day readmission rates (adjusted odds ratio [aOR]: 1.67, 95% confidence interval [CI]: 1.12-2.50, P = 0.01). However, opioid dependence was associated with lower in-hospital (aOR: 0.16, CI: 0.07-0.38, P < 0.01) and 1-year (aOR: 0.15, CI: 0.06-0.38, P < 0.01) mortality, longer mean length of stay (adjusted mean difference [aMD]: 2.09 d, CI: 0.43-3.76, P = 0.03), and total hospitalization costs (aMD: $6,318, CI: $ 257-$12,380, P = 0.04). Both groups had similar total hospitalization charges (aMD: $$10,491, CI: -$12,618-$33,600, P-value = 0.37). CONCLUSIONS: Opioid dependence leads to higher rates of 30-day readmission and resource utilization among patients with firearm injuries. However, the in-hospital and 1-year mortality rates are lower among patients with opioid dependence secondary to lower injury acuity.

The financial burden of musculoskeletal firearm injuries in children with and without concomitant intra-cavitary injuries.

BACKGROUND: Musculoskeletal pediatric firearm injuries are a clinically significant and expensive public health problem in the United States. In this retrospective cohort analysis, we sought to characterize musculoskeletal firearm injuries in children and to describe the financial burden associated with these injuries. METHODS: This study is a single center, retrospective review. Patients were identified from January 2002 - December 2015 from an institutional database using ICD-9 codes pertaining to firearm injury. Inclusion criteria were: 1) age < 18 years at injury; 2) firearm injury to an extremity, spine, or pelvis; and 3) patient received orthopedic evaluation and/or treatment. 140 patients with 142 distinct orthopedic injuries meeting inclusion criteria were analyzed (N = 142). Primary measures were demographic and situational data including intent, length of stay, follow-up, and complications; and financial outcomes including charges, costs, and net revenues. RESULTS: Median age was 15.3 years [IQR: 13.3, 16.4], 84% were male, and 52% were African American. 59% of the firearm injuries were of violent intent. 32% of patients were privately insured, 61% were publicly insured, and 6% were uninsured. Median length of stay was 2 days [0, 4], with 73% of patients being admitted. 43% of patients required additional hospitalizations, emergency room visits, and/or outpatient surgeries, and 93% of patients had outpatient follow-up. 42% of patients experience an injury-related or long-term orthopedic complication. Total charges for the cohort were $11.4 million, with $3.7 million in costs and $45,042 in net revenues. In the multivariable analysis, more surgeries predicted higher charges, and more secondary encounters predicted higher costs and net revenues. Only privately-insured patients had a positive median net revenue. CONCLUSIONS: Children who sustain musculoskeletal injuries from firearms experience high rates of orthopedic complications. Institutional costs to manage these preventable injuries are excessive. Policy makers should continue to pursue measures to reduce gun violence and improve gun safety in the pediatric population. LEVEL OF EVIDENCE: Level III, economic/decision.
