Item A commentary on domestic firearm violence against women (2018–2021)(Elsevier, 2024-02-20) Schutzman, Linda M.; Jenkins, Peter C.; Surgery, School of MedicineThe COVID-19 pandemic has exposed some of our best and worst qualities as a country. This commentary on “Domestic Firearm Violence Against Women (2018-2021)” discusses weaknesses in federal legislation and proposes ways for states to fill these gaps.Item Asynchronous Conferencing Through a Secure Messaging Application Increases Reporting of Medical Errors in a Mature Trauma Center(Sage, 2023) Lee, Joy L.; Isenberg, Scott; Adams, Georgann; Thurston, Maria; Hammer, Peter M.; Mohanty, Sanjay K.; Jenkins, Peter C.; Surgery, School of MedicineBackground: Medical errors occur frequently, yet they are often under-reported and strategies to increase the reporting of medical errors are lacking. In this work, we detail how a level 1 trauma center used a secure messaging application to track medical errors and enhance its quality improvement initiatives. Methods: We describe the formulation, implementation, evolution, and evaluation of a chatroom integrated into a secure texting system to identify performance improvement and patient safety (PIPS) concerns. For evaluation, we used descriptive statistics to examine PIPS reporting by the reporting method over time, the incidence of mortality and unplanned ICU readmissions tracked in the hospital trauma registry over the same, and time-to-loop closure over the study period to quantify the impact of the processes instituted by the PIPS team. We also categorized themes of reported events. Results: With the implementation of a PIPS chatroom, the number of events reported each month increased and texting became the predominant way for users to report trauma PIPS events. This increase in PIPS reporting did not appear to be accompanied by an increase in mortality and unplanned ICU readmissions. The PIPS team also improved the tracking and timely resolution of PIPS events and observed a decrease in time-to-loop closure with the implementation of the PIPS chatroom. Conclusions: The adoption of clinical texting as a way to report PIPS events was associated with increased reporting of such events and more timely resolution of concerns regarding patient safety and healthcare quality.Item Clinical indicators of hemorrhagic shock in pregnancy(BMJ, 2017-11-07) Jenkins, Peter C.; Stokes, Samantha M.; Fakoyeho, Stephen; Bell, Teresa M.; Zarzaur, Ben L.; Surgery, School of MedicineBackground Several hemodynamic parameters have been promoted to help establish a rapid diagnosis of hemorrhagic shock, but they have not been well validated in the pregnant population. In this study, we examined the association between three measures of shock and early blood transfusion requirements among pregnant trauma patients. Methods This study included 81 pregnant trauma patients admitted to a level 1 trauma center (2010–2015). In separate logistic regression models, we tested the relationship between exposure variables—initial systolic blood pressure (SBP), shock index (SI), and rate over pressure evaluation (ROPE)—and the outcome of transfusion of blood products within 24 hours of admission. To test the predictive ability of each measure, we used receiver operating characteristic (ROC) curves. Results A total of 10% of patients received blood products in the patient cohort. No patients had an initial SBP≤90, so the SBP measure was excluded from analysis. We found that patients with SI>1 were significantly more likely to receive blood transfusions compared with patients with SI<1 (OR 10.35; 95% CI 1.80 to 59.62), whereas ROPE>3 was not associated with blood transfusion compared with ROPE≤3 (OR 2.92; 95% CI 0.28 to 30.42). Furthermore, comparison of area under the ROC curve for SI (0.68) and ROPE (0.54) suggested that SI was more predictive than ROPE of blood transfusion. Conclusion We found that an elevated SI was more closely associated with early blood product transfusion than SBP and ROPE in injured pregnant patients. Level of evidence Prognostic, level IIIItem Comparison of a Trauma Comorbidity Index with Other Measures of Comorbidities to Estimate Risk of Trauma Mortality(Wiley Online Library, 2021-04-29) Jenkins, Peter C.; Dixon, Brian E.; Savage, Stephanie A.; Carroll, Aaron E.; Newgard, Craig D.; Tignanelli, Christopher J.; Hemmila, Mark R.; Timsina, Lava; Surgery, School of MedicineBackground Comorbidities influence the outcomes of injured patients, yet a lack of consensus exists regarding how to quantify that association. This study details the development and internal validation of a trauma comorbidity index (TCI) designed for use with trauma registry data and compares its performance to other existing measures to estimate the association between comorbidities and mortality. Methods Indiana state trauma registry data (2013-2015) was used to compare the TCI with the Charlson and Elixhauser comorbidity indices, a count of comorbidities, and comorbidities as separate variables. The TCI approach utilized a randomly selected training cohort and was internally validated in a distinct testing cohort. The C-statistic of the adjusted models was tested using each comorbidity measure in the testing cohort to assess model discrimination. C-statistics were compared using a Wald test, and stratified analyses were performed based on predicted risk of mortality. Multiple imputation was used to address missing data. Results The study included 84,903 patients (50% each in training and testing cohorts). The Indiana TCI model demonstrated no significant difference between testing and training cohorts (p = 0.33). It produced a C-statistic of 0.924 in the testing cohort, which was significantly greater than that of models using the other indices (p < 0.05). The C-statistics of models using the Indiana TCI and the inclusion of comorbidities as separate variables – the method used by the American College of Surgeons Trauma Quality Improvement Program – were comparable (p = 0.11) but use of the TCI approach reduced the number of comorbidity-related variables in the mortality model from 19 to one. Conclusions When examining trauma mortality, the TCI approach using Indiana state trauma registry data demonstrated superior model discrimination and/or parsimony compared to other measures of comorbidities.Item The conference effect: National surgery meetings are associated with increased mortality at trauma centers without American College of Surgeons verification(PLOS, 2019-03-26) Jenkins, Peter C.; Painter, Scott; Bell, Teresa M.; Kline, Jeffrey A.; Zarzaur, Ben L.; Surgery, School of MedicineBACKGROUND: Thousands of physicians attend scientific conferences each year. While recent data indicate that variation in staffing during such meetings impacts survival of non-surgical patients, the association between treatment during conferences and outcomes of a surgical population remain unknown. The purpose of this study was to examine mortality resulting from traumatic injuries and the influence of hospital admission during national surgery meetings. STUDY DESIGN: Retrospective analysis of in-hospital mortality using data from the Trauma Quality Improvement Program (2010-2011). Identified patients admitted during four annual meetings and compared their mortality with that of patients admitted during non-conference periods. Analysis included 155 hospitals with 12,256 patients admitted on 42 conference days and 82,399 patients admitted on 270 non-conference days. Multivariate analysis performed separately for hospitals with different levels of trauma center verification by state and American College of Surgeons (ACS) criteria. RESULTS: Patient characteristics were similar between meeting and non-meeting dates. At ACS level I and level II trauma centers during conference versus non-conference dates, adjusted mortality was not significantly different. However, adjusted mortality increased significantly for patients admitted to trauma centers that lacked ACS trauma verification during conferences versus non-conference days (OR 1.2, p = 0.008), particularly for patients with penetrating injuries, whose mortality rose from 11.6% to 15.9% (p = 0.006). CONCLUSIONS: Trauma mortality increased during surgery conferences compared to non-conference dates for patients admitted to hospitals that lacked ACS trauma level verification. The mortality difference at those hospitals was greatest for patients who presented with penetrating injuries.Item The Effect of Trauma Center Verification on Outcomes of Traumatic Brain Injury Patients Undergoing Interfacility Transfer(Wiley, 2021) Jenkins, Peter C.; Newgard, Craig; Surgery, School of MedicineItem Emergency Department Pediatric Readiness and Disparities in Mortality Based on Race and Ethnicity(American Medical Association, 2023-09-05) Jenkins, Peter C.; Lin, Amber; Ames, Stefanie G.; Newgard, Craig D.; Lang, Benjamin; Winslow, James E.; Marin, Jennifer R.; Cook, Jennifer N. B.; Goldhaber-Fiebert, Jeremy D.; Papa, Linda; Zonfrillo, Mark R.; Hansen, Matthew; Wall, Stephen P.; Malveau, Susan; Kuppermann, Nathan; Pediatric Readiness Study Group; Surgery, School of MedicineImportance: Presentation to emergency departments (EDs) with high levels of pediatric readiness is associated with improved pediatric survival. However, it is unclear whether children of all races and ethnicities benefit equitably from increased levels of such readiness. Objective: To evaluate the association of ED pediatric readiness with in-hospital mortality among children of different races and ethnicities with traumatic injuries or acute medical emergencies. Design, setting, and participants: This cohort study of children requiring emergency care in 586 EDs across 11 states was conducted from January 1, 2012, through December 31, 2017. Eligible participants included children younger than 18 years who were hospitalized for an acute medical emergency or traumatic injury. Data analysis was conducted between November 2022 and April 2023. Exposure: Hospitalization for acute medical emergency or traumatic injury. Main outcomes and measures: The primary outcome was in-hospital mortality. ED pediatric readiness was measured through the weighted Pediatric Readiness Score (wPRS) from the 2013 National Pediatric Readiness Project assessment and categorized by quartile. Multivariable, hierarchical, mixed-effects logistic regression was used to evaluate the association of race and ethnicity with in-hospital mortality. Results: The cohort included 633 536 children (median [IQR] age 4 [0-12] years]). There were 557 537 children (98 504 Black [17.7%], 167 838 Hispanic [30.1%], 311 157 White [55.8%], and 147 876 children of other races or ethnicities [26.5%]) who were hospitalized for acute medical emergencies, of whom 5158 (0.9%) died; 75 999 children (12 727 Black [16.7%], 21 604 Hispanic [28.4%], 44 203 White [58.2%]; and 21 609 of other races and ethnicities [27.7%]) were hospitalized for traumatic injuries, of whom 1339 (1.8%) died. Adjusted mortality of Black children with acute medical emergencies was significantly greater than that of Hispanic children, White children, and of children of other races and ethnicities (odds ratio [OR], 1.69; 95% CI, 1.59-1.79) across all quartile levels of ED pediatric readiness; but there were no racial or ethnic disparities in mortality when comparing Black children with traumatic injuries with Hispanic children, White children, and children of other races and ethnicities with traumatic injuries (OR 1.01; 95% CI, 0.89-1.15). When compared with hospitals in the lowest quartile of ED pediatric readiness, children who were treated at hospitals in the highest quartile had significantly lower mortality in both the acute medical emergency cohort (OR 0.24; 95% CI, 0.16-0.36) and traumatic injury cohort (OR, 0.39; 95% CI, 0.25-0.61). The greatest survival advantage associated with high pediatric readiness was experienced for Black children in the acute medical emergency cohort. Conclusions and relevance: In this study, racial and ethnic disparities in mortality existed among children treated for acute medical emergencies but not traumatic injuries. Increased ED pediatric readiness was associated with reduced disparities; it was estimated that increasing the ED pediatric readiness levels of hospitals in the 3 lowest quartiles would result in an estimated 3-fold reduction in disparity for pediatric mortality. However, increased pediatric readiness did not eliminate disparities, indicating that organizations and initiatives dedicated to increasing ED pediatric readiness should consider formal integration of health equity into efforts to improve pediatric emergency care.Item Emergency Department Pediatric Readiness and Short-term and Long-term Mortality Among Children Receiving Emergency Care(American Medical Association, 2023-01-03) Newgard, Craig D.; Lin, Amber; Malveau, Susan; Cook, Jennifer N. B.; Smith, McKenna; Kuppermann, Nathan; Remick, Katherine E.; Gausche-Hill, Marianne; Goldhaber-Fiebert, Jeremy; Burd, Randall S.; Hewes, Hilary A.; Salvi, Apoorva; Xin, Haichang; Ames, Stefanie G.; Jenkins, Peter C.; Marin, Jennifer; Hansen, Matthew; Glass, Nina E.; Nathens, Avery B.; McConnell, K. John; Dai, Mengtao; Carr, Brendan; Ford, Rachel; Yanez, Davis; Babcock, Sean R.; Lang, Benjamin; Mann, N. Clay; Pediatric Readiness Study Group; Surgery, School of MedicineImportance: Emergency departments (EDs) with high pediatric readiness (coordination, personnel, quality improvement, safety, policies, and equipment) are associated with lower mortality among children with critical illness and those admitted to trauma centers, but the benefit among children with more diverse clinical conditions is unknown. Objective: To evaluate the association between ED pediatric readiness, in-hospital mortality, and 1-year mortality among injured and medically ill children receiving emergency care in 11 states. Design, setting, and participants: This is a retrospective cohort study of children receiving emergency care at 983 EDs in 11 states from January 1, 2012, through December 31, 2017, with follow-up for a subset of children through December 31, 2018. Participants included children younger than 18 years admitted, transferred to another hospital, or dying in the ED, stratified by injury vs medical conditions. Data analysis was performed from November 1, 2021, through June 30, 2022. Exposure: ED pediatric readiness of the initial ED, measured through the weighted Pediatric Readiness Score (wPRS; range, 0-100) from the 2013 National Pediatric Readiness Project assessment. Main outcomes and measures: The primary outcome was in-hospital mortality, with a secondary outcome of time to death to 1 year among children in 6 states. Results: There were 796 937 children, including 90 963 (11.4%) in the injury cohort (mean [SD] age, 9.3 [5.8] years; median [IQR] age, 10 [4-15] years; 33 516 [36.8%] female; 1820 [2.0%] deaths) and 705 974 (88.6%) in the medical cohort (mean [SD] age, 5.8 [6.1] years; median [IQR] age, 3 [0-12] years; 329 829 [46.7%] female, 7688 [1.1%] deaths). Among the 983 EDs, the median (IQR) wPRS was 73 (59-87). Compared with EDs in the lowest quartile of ED readiness (quartile 1, wPRS of 0-58), initial care in a quartile 4 ED (wPRS of 88-100) was associated with 60% lower in-hospital mortality among injured children (adjusted odds ratio, 0.40; 95% CI, 0.26-0.60) and 76% lower mortality among medical children (adjusted odds ratio, 0.24; 95% CI, 0.17-0.34). Among 545 921 children followed to 1 year, the adjusted hazard ratio of death in quartile 4 EDs was 0.59 (95% CI, 0.42-0.84) for injured children and 0.34 (95% CI, 0.25-0.45) for medical children. If all EDs were in the highest quartile of pediatric readiness, an estimated 288 injury deaths (95% CI, 281-297 injury deaths) and 1154 medical deaths (95% CI, 1150-1159 medical deaths) may have been prevented. Conclusions and relevance: These findings suggest that children with injuries and medical conditions treated in EDs with high pediatric readiness had lower mortality during hospitalization and to 1 year.Item Evaluation of Emergency Department Pediatric Readiness and Outcomes Among US Trauma Centers(American Medical Association, 2021) Newgard, Craig D.; Lin, Amber; Olson, Lenora M.; Cook, Jennifer N.B.; Gausche-Hill, Marianne; Kuppermann, Nathan; Goldhaber-Fiebert, Jeremy D.; Malveau, Susan; Smith, McKenna; Dai, Mengtao; Nathens, Avery B.; Glass, Nina E.; Jenkins, Peter C.; McConnell, K. John; Remick, Katherine E.; Hewes, Hilary; Mann, N. Clay; Pediatric Readiness Study Group; Surgery, School of MedicineImportance: The National Pediatric Readiness Project is a US initiative to improve emergency department (ED) readiness to care for acutely ill and injured children. However, it is unclear whether high ED pediatric readiness is associated with improved survival in US trauma centers. Objective: To evaluate the association between ED pediatric readiness, in-hospital mortality, and in-hospital complications among injured children presenting to US trauma centers. Design, setting, and participants: A retrospective cohort study of 832 EDs in US trauma centers in 50 states and the District of Columbia was conducted using data from January 1, 2012, through December 31, 2017. Injured children younger than 18 years who were admitted, transferred, or with injury-related death in a participating trauma center were included in the analysis. Subgroups included children with an Injury Severity Score (ISS) of 16 or above, indicating overall seriously injured (accounting for all injuries); any Abbreviated Injury Scale (AIS) score of 3 or above, indicating at least 1 serious injury; a head AIS score of 3 or above, indicating serious brain injury; and need for early use of critical resources. Exposures: Emergency department pediatric readiness for the initial ED visit, measured through the weighted Pediatric Readiness Score (range, 0-100) from the 2013 National Pediatric Readiness Project ED pediatric readiness assessment. Main outcomes and measures: In-hospital mortality, with a secondary composite outcome of in-hospital mortality or complication. For the primary measurement tools used, the possible range of the AIS is 0 to 6, with 3 or higher indicating a serious injury; the possible range of the ISS is 0 to 75, with 16 or higher indicating serious overall injury. The weighted Pediatric Readiness Score examines and scores 6 domains; in this study, the lowest quartile included scores of 29 to 62 and the highest quartile included scores of 93 to 100. Results: There were 372 004 injured children (239 273 [64.3%] boys; median age, 10 years [interquartile range, 4-15 years]), including 5700 (1.5%) who died in-hospital and 5018 (1.3%) who developed in-hospital complications. Subgroups included 50 440 children (13.6%) with an ISS of 16 or higher, 124 507 (33.5%) with any AIS score of 3 or higher, 57 368 (15.4%) with a head AIS score of 3 or higher, and 32 671 (8.8%) requiring early use of critical resources. Compared with EDs in the lowest weighted Pediatric Readiness Score quartile, children cared for in the highest ED quartile had lower in-hospital mortality (adjusted odds ratio [aOR], 0.58; 95% CI, 0.45-0.75), but not fewer complications (aOR for the composite outcome 0.88; 95% CI, 0.74-1.04). These findings were consistent across subgroups, strata, and multiple sensitivity analyses. If all children cared for in the lowest-readiness quartiles (1-3) were treated in an ED in the highest quartile of readiness, an additional 126 lives (95% CI, 97-154 lives) might be saved each year in these trauma centers. Conclusions and relevance: In this cohort study, injured children treated in high-readiness EDs had lower mortality compared with similar children in low-readiness EDs, but not fewer complications. These findings support national efforts to increase ED pediatric readiness in US trauma centers that care for children.Item Extending Trauma Quality Improvement Beyond Trauma Centers: Hospital Variation in Outcomes Among Nontrauma Hospitals(Wolters Kluwer, 2022) Jenkins, Peter C.; Timsina, Lava; Murphy, Patrick; Tignanelli, Christopher; Holena, Daniel N.; Hemmila, Mark R.; Newgard, Craig; Surgery, School of MedicineObjective: The American College of Surgeons (ACS) conducts a robust quality improvement program for ACS-verified trauma centers, yet many injured patients receive care at non-accredited facilities. This study tested for variation in outcomes across non-trauma hospitals and characterized hospitals associated with increased mortality. Summary background data: The study included state trauma registry data of 37,670 patients treated between January 1, 2013, and December 31, 2015. Clinical data were supplemented with data from the American Hospital Association and US Department of Agriculture, allowing comparisons among 100 nontrauma hospitals. Methods: Using Bayesian techniques, risk-adjusted and reliability-adjusted rates of mortality and interfacility transfer, as well as Emergency Departments length-of-stay (ED-LOS) among patients transferred from EDs were calculated for each hospital. Subgroup analyses were performed for patients ages >55 years and those with decreased Glasgow coma scores (GCS). Multiple imputation was used to address missing data. Results: Mortality varied 3-fold (0.9%-3.1%); interfacility transfer rates varied 46-fold (2.1%-95.6%); and mean ED-LOS varied 3-fold (81-231 minutes). Hospitals that were high and low statistical outliers were identified for each outcome, and subgroup analyses demonstrated comparable hospital variation. Metropolitan hospitals were associated increased mortality [odds ratio (OR) 1.7, P = 0.004], decreased likelihood of interfacility transfer (OR 0.7, P ≤ 0.001), and increased ED-LOS (coef. 0.1, P ≤ 0.001) when compared with nonmetropolitan hospitals and risk-adjusted. Conclusions: Wide variation in trauma outcomes exists across nontrauma hospitals. Efforts to improve trauma quality should include engagement of nontrauma hospitals to reduce variation in outcomes of injured patients treated at those facilities.
