Abstract
INTRODUCTION Time-To-OR is a critical process measure for trauma performance. However, this measure has not consistently demonstrated improvement in outcome. STUDY DESIGN Using TQIP, we identified facilities by 75th percentile time-to-OR to categorize slow, average, and fast hospitals. Using a GEE model, we calculated odds of mortality for all penetrating abdominal trauma patients, firearm injuries only, and patients with major complication by facility speed. We additionally estimated odds of mortality at the patient level. RESULTS Odds of mortality for patients at slow facilities was 1.095; 95% CI: 0.746, 1.608; p = 0.64 compared to average. Fast facility OR = 0.941; 95% CI: 0.780, 1.133; p = 0.52. At the patient-level each additional minute of time-to-OR was associated with 1.5% decreased odds of in-hospital mortality (OR 0.985; 95% CI:0.981, 0.989; p < 0.001). For firearm-only patients, facility speed was not associated with odds of in-hospital mortality (p-value = 0.61). Person-level time-to-OR was associated with 1.8% decreased odds of in-hospital mortality (OR 0.982; 95% CI: 0.977, 0.987; p < 0.001) with each additional minute of time-to-OR. Similarly, failure-to-rescue analysis showed no difference in in-hospital mortality at the patient level (p = 0.62) and 0.4% decreased odds of in-hospital mortality with each additional minute of time-to-OR at the patient level (OR 0.996; 95% CI: 0.993, 0.999; p = 0.004). CONCLUSION Despite the use of time-to-OR as a metric of trauma performance, there is little evidence for improvement in mortality or complication rate with improved time-to-OR at the facility or patient level. Performance metrics for trauma should be developed that more appropriately approximate patient outcome.

Abstract
BACKGROUND After officer-involved shootings (OIS), rapid delivery of emergency medical care is critical but may be delayed due to scene safety concerns. The purpose of this study was to describe medical care rendered by law enforcement officers (LEOs) after lethal force incidents. METHODS Retrospective analysis of open-source video footage of OIS occurring from February 15, 2013 through December 31, 2020. Frequency and nature of care provided, time until LEO and Emergency Medical Services (EMS) care, and mortality outcomes were evaluated. The study was deemed exempt by the Mayo Clinic Institutional Review Board. RESULTS Three hundred forty-two (342) videos were included in the final analysis; LEOs rendered care in 172 (50.3%) incidents. Average elapsed time from time-of-injury (TOI) to LEO-provided care was 155.8 (SD = 198.8) seconds. Hemorrhage control was the most common intervention performed. An average of 214.2 seconds elapsed between LEO care and EMS arrival. No mortality difference was identified between LEO versus EMS care (P = .1631). Subjects with truncal wounds were more likely to die than those with extremity wounds (P < .00001). CONCLUSIONS It was found that LEOs rendered medical care in one-half of all OIS incidents, initiating care on average 3.5 minutes prior to EMS arrival. Although no significant mortality difference was noted for LEO versus EMS care, this finding must be interpreted cautiously, as specific interventions, such as extremity hemorrhage control, may have impacted select patients. Future studies are needed to determine optimal LEO care for these patients.

Abstract
Importance The burden of firearm violence in US cities continues to rise. The role of access to trauma center care as a trauma system measure with implications for firearm injury mortality has not been comprehensively evaluated. Objective To evaluate the association between geospatial access to care and firearm injury mortality in an urban trauma system. Design, Setting, and Participants Retrospective cohort study of all people 15 years and older shot due to interpersonal violence in Philadelphia, Pennsylvania, between January 1, 2015, and August 9, 2021. Exposures Geospatial access to care, defined as the predicted ground transport time to the nearest trauma center for each person shot, derived by geospatial network analysis. Main Outcomes and Measures Risk-adjusted mortality estimated using hierarchical logistic regression. The population attributable fraction was used to estimate the proportion of fatalities attributable to disparities in geospatial access to care. Results During the study period, 10 105 people (910 [9%] female and 9195 [91%] male; median [IQR] age, 26 [21-28] years; 8441 [84%] Black, 1596 [16%] White, and 68 other [<1%], including Asian and unknown, consolidated owing to small numbers) were shot due to interpersonal violence in Philadelphia. Of these, 1999 (20%) died. The median (IQR) predicted transport time was 5.6 (3.8-7.2) minutes. After risk adjustment, each additional minute of predicted ground transport time was associated with an increase in odds of mortality (odds ratio [OR], 1.03 per minute; 95% CI, 1.01-1.05). Calculation of the population attributable fraction using mortality rate ratios for incremental 1-minute increases in predicted ground transport time estimated that 23% of shooting fatalities could be attributed to differences in access to care, equivalent to 455 deaths over the study period. Conclusions and Relevance These findings indicate that geospatial access to care may be an important trauma system measure, improvements to which may result in reduced deaths from gun violence in US cities.

Change in outcomes for trauma patients over time: Two decades of a state trauma system. Injury 2022; 53:2915-2922. [PMID: 35752485 DOI: 10.1016/j.injury.2022.06.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/19/2022] [Revised: 05/26/2022] [Accepted: 06/09/2022] [Indexed: 02/02/2023]
Abstract
BACKGROUND Trauma center mortality rates are benchmarked to expected rates of death based on patient and injury characteristics. The expected mortality rate is recalculated from pooled outcomes across a trauma system each year, obscuring system-level change across years. We hypothesized that risk-adjusted mortality would decrease over time within a state-wide trauma system. METHODS We identified adult trauma patients presenting to Level I and II Pennsylvania trauma centers, 1999-2018, using the Pennsylvania Trauma Outcomes Study. Multivariable logistic regression generated risk-adjusted models for mortality in all patients, and in key subgroups: penetrating torso injury, blunt multisystem trauma, and patients presenting in shock. RESULTS Of 162,646 included patients, 123,518 (76.1%) were white and 108,936 (67.0%) were male. The median age was 49 (interquartile range [IQR] 29-70), median injury severity score was 16 (IQR 10-24), and 87.5% of injuries were blunt. Overall, 9.9% of patients died, and compared to 1999, no year had significantly higher adjusted odds of mortality. Overall mortality was significantly lower in 2007-2009 and 2011-2018. Of patients with blunt, multisystem injuries, 17.7% died, and adjusted mortality improved over time. Mortality rates were 24.9% for penetrating torso injury, and 56.9% for shock, with no significant change. Mortality improved for patients with ISS < 25, but not for the most severely injured. CONCLUSIONS Over 20 years, Pennsylvania trauma centers demonstrated improved risk-adjusted mortality rates overall, but improvement remains lacking in high-risk groups despite numerous innovations and practice changes in this time period. Identifying change over time can help guide focus to these critical gaps.

Abstract
BACKGROUND Police transport (PT) of penetrating trauma patients in urban locations has become routine in certain metropolitan areas; however, whether it results in improved outcomes over prehospital Advanced life support (ALS) transport has not been determined in a multicenter study. We hypothesized that PT would not result in improved outcomes. METHODS This was a multicenter, prospective, observational study of adults (18+ years) with penetrating trauma to the torso and/or proximal extremity presenting at 25 urban trauma centers. Police transport and ALS patients were allocated via nearest neighbor, propensity matching. Transport mode also examined by Cox regression. RESULTS Of 1,618 total patients, 294 (18.2%) had PT and 1,324 (81.8%) were by ALS. After matching, 588 (294/cohort) remained. The patients were primarily Black (n = 497, 84.5%), males (n = 525, 89.3%, injured by gunshot wound (n = 494, 84.0%) with 34.5% (n = 203) having Injury Severity Score of 16 or higher. Overall mortality by propensity matching was not different between cohorts (15.6% ALS vs. 15.0% PT, p = 0.82). In severely injured patients (Injury Severity Score ≥16), mortality did not differ between PT and ALS transport (38.8% vs. 36.0%, respectively; p = 0.68). Cox regression analysis controlled for relevant factors revealed no association with a mortality benefit in patients transported by ALS. CONCLUSION Police transport of penetrating trauma patients in urban locations results in similar outcomes compared with ALS. Immediate transport to definitive trauma care should be emphasized in this patient population. LEVEL OF EVIDENCE Prognostic and Epidemiologic; Level III.

Abstract
Background Traumatic tension pneumothoraces (TPT) are among the most serious causes of death in traumatic injuries, requiring immediate treatment with a needle thoracostomy (NT). Improperly placed NT insertion into the pleural cavity may fail to treat a life-threatening TPT. This study aimed to assess the accuracy of prehospital NT placements by paramedics in adult trauma patients. Methods A retrospective chart review was performed on 84 consecutive trauma patients who had received NT by prehospital personnel. The primary outcome was the accuracy of NT placement by prehospital personnel. Comparisons of various variables were conducted between those who survived and those who died, and proper versus improper needle insertion separately. Results Proper NT placement into the pleural cavity was noted in 27.4% of adult trauma patients. In addition, more than 19% of the procedures performed by the prehospital providers appeared to have not been medically indicated. Discussion Long-term strategies may be needed to improve the capabilities and performance of prehospital providers' capabilities in this delicate life-saving procedure. Level of evidence IV.
