Sex-related disparities in vehicle crash injury and hemodynamics.

Objective: Multiple studies evaluate relative risk of female vs. male crash injury; clinical data may offer a more direct injury-specific evaluation of sex disparity in vehicle safety. This study sought to evaluate trauma injury patterns in a large trauma database to identify sex-related differences in crash injury victims. Methods: Data on lap and shoulder belt wearing patients age 16 and up with abdominal and pelvic injuries from 2018 to 2021 were extracted from the National Trauma Data Bank for descriptive analysis using injuries, vital signs, International Classification of Disease (ICD) coding, age, and injury severity using AIS (Abbreviated Injury Scale) and ISS (Injury Severity Score). Multiple linear regression was used to assess the relationship of shock index (SI) and ISS, sex, age, and sex*age interaction. Regression analysis was performed on multiple injury regions to assess patient characteristics related to increased shock index. Results: Sex, age, and ISS are strongly related to shock index for most injury regions. Women had greater overall SI than men, even in less severe injuries; women had greater numbers of pelvis and liver injuries across severity categories; men had greater numbers of injury in other abdominal/pelvis injury regions. Conclusions: Female crash injury victims' tendency for higher (AIS) severity of pelvis and liver injuries may relate to how their bodies interact with safety equipment. Females are entering shock states (SI > 1.0) with lesser injury severity (ISS) than male crash injury victims, which may suggest that female crash patients are somehow more susceptible to compromised hemodynamics than males. These findings indicate an urgent need to conduct vehicle crash injury research within a sex-equity framework; evaluating sex-related clinical data may hold the key to reducing disparities in vehicle crash injury.

A Pilot Project of a Post Discharge Care Team for Firearm Injury Survivors Decreases Emergency Department Utilization, Hospital Readmission Days, and Cost.

BACKGROUND: Persons of low socioeconomic status are overrepresented in the firearm injury patient population and may experience challenges in accessing complex outpatient health systems. Consequently, outpatient care for these patients is plagued by poor follow-up and increased emergency department (ED) utilization. We developed a Post Discharge Care Team (PDCT) consisting of a dedicated trauma nurse navigator and medical social worker to bridge the gap between hospital discharge and outpatient care to improve recovery. METHODS: Adult firearm injury survivors admitted to the trauma service were randomized 1:1 to receive either PDCT services or standard of care (SOC) workflows. The PDCT nurse provided education and set expectations regarding injuries, wound care, and outpatient follow up. The PDCT social worker performed a comprehensive assessment to identify concerns including housing and financial instability, food insecurity, or transportation issues. The primary outcome was ED utilization, with secondary outcomes including readmissions and overall healthcare costs compared between groups. RESULTS: In the first six months of the study, a total of 44 patients were randomized to PDCT and 47 to SOC. There were 10 patients who visited the ED in the PDCT group compared to 16 in the SOC group (p = 0.23) for a total of 14 and 23 ED visits, respectively. There were 14 patients in the PDCT and 11 patients in the SOC groups who were readmitted (p = 0.31), but the PDCT group was readmitted for 27.9 fewer hospital days. After accounting for programmatic costs, the PDCT had a hospital savings of $34,542.71. CONCLUSION: A collaborative, specialized Post Discharge Care Team for firearm injury survivors consisting of a dedicated trauma nurse navigator and medical social worker decreased outpatient ED utilization, readmission days, and was cost effective. Trauma centers with high volumes of penetrating trauma should consider a similar model to improve outpatient care for firearm injury survivors.

Trends in Adult Suicide Rates in Milwaukee County, Wisconsin, 2002 through 2020.

BACKGROUND: Monitoring suicide rates is an important public health strategy to inform prevention efforts. We describe rates of adult suicide in Milwaukee County, Wisconsin, over a 19-year period. METHODS: Data on all adult suicides from 2002 through 2020 (n = 981) were obtained from the Milwaukee County Medical Examiner's Office. Subpopulation rates were identified using the Wisconsin Interactive Statistics on Health System. RESULTS: Suicide rates increased significantly over the study period, with disproportionate increases among Black and Latinx residents. DISCUSSION: Expanded prevention efforts are needed to reverse this concerning trend. Further research should guide development of culturally relevant interventions, provide data for the equitable allocation of limited resources.

Suicide Data in Trauma Centers: Implications of Imprecision.

BACKGROUND: Trauma registries exist to provide data for evaluating the quality of care of trauma patients. These data facilitate research and can be used for outreach, planning, and improvement in trauma patient outcomes. However, the accuracy of registry data related to suicide has not been well studied. OBJECTIVE: This study sought to evaluate the accuracy of current trauma registry coding practices related to labeling injury as a suicide attempt among patients presenting to a Level I trauma center after self-inflicted injury. METHODS: We conducted a single-center, retrospective cohort analysis of a Level I trauma center trauma registry on all patients with self-inflicted injuries from 2011 to 2021. Manual chart review was used to identify cases wherein patients' injuries were categorized as suicidal despite the absence of suicidal intent. RESULTS: During this 11-year period, 537 patients were identified as having presented to the trauma center for traumatic self-inflicted injuries. Manual chart review revealed that 16% of these patients were incorrectly categorized as having attempted suicide despite their self-inflicted injury lacking suicidal intent (e.g., accidents, nonsuicidal self-harm). CONCLUSION: We found that 16% of trauma registry patients were overcategorized as having attempted suicide. Trauma registry data are an important source of information for activities related to injury prevention in trauma centers. Imprecise coding of self-inflicted injury may lead to poorly targeted programs and interventions due to incorrectly represented injury causes and patterns in trauma patient populations, including suicide prevention.

Mechanisms of traumatic injury by demographic characteristics: an 8-year review of temporal trends from the National Trauma Data Bank.

BACKGROUND/PURPOSE: This 8-year retrospective study of the National Trauma Data Bank describes temporal trends of traumatic injury by mechanism of injury (MOI) by demographic characteristics from 2012 to 2019 for adult patients 18 years and older. METHODS: Overall, 5 630 461 records were included after excluding those with missing demographic information and International Classification of Disease codes. MOIs were calculated as proportions of total injury by year. Temporal trends of MOI were evaluated using two-sided non-parametric Mann-Kendall trend tests for (1) all patients and (2) within racial and ethnic groups (ie, Asian, 2% of total patient sample; Black, 14%; Hispanic or Latino, 10%; Multiracial, 3%; Native American, <1%; Pacific Islander, <1%; White, 69%) and stratified by age and sex. RESULTS/OUTCOMES: For all patients, falls increased over time (p=0.001), whereas burn (p<0.01), cut/pierce (p<0.01), cyclist (p=0.01), machinery (p<0.001), motor vehicle transport (MVT) motorcyclist (p<0.001), MVT occupant (p<0.001) and other blunt trauma (p=0.03) injuries decreased over time. The proportion of falls increased across all racial and ethnic groups and significantly for those aged 65 and older. There were further differences in decreasing trends of MOI by racial and ethnic categories and by age groups. CONCLUSIONS: These results suggest that falls are an important injury prevention target with an ageing US population across all racial and ethnic groups. Differing injury profiles by racial and ethnic identity indicate that injury prevention efforts be designed accordingly and targeted specifically to individuals most at risk for specific MOIs. STUDY TYPE: Level I, prognostic/epidemiological.

Use of Theory in Quality Innovations: Shift Change Protocol in the Emergency Department.

BACKGROUND: Inconsistent and nonstandardized patient handoffs can increase the risk of adverse events. Using change theory may promote adoption of effective handoff processes. LOCAL PROBLEM: A Midwest emergency department (ED) had no standardized practice for shift change handoffs. Previous handoff quality improvement efforts had been unsuccessful. METHODS: A pre/postintervention pilot project design was used. Nurses' compliance with the new handoff protocol was evaluated. INTERVENTIONS: Using Diffusion of Innovation (DOI) theory, an evidence-based shift change protocol was designed and implemented, which included a comprehensive handoff tool specific to the ED. RESULTS: Four elements in the new shift change process saw statistically significant improvements after implementation, including discussion of the patient's illness severity ( P = .001), synthesis of the patient's care ( P < .001), completing a bedside safety checklist ( P < .001), and providing a formal transition-of-care process ( P < .001). CONCLUSIONS: Using DOI theory may improve the adoption of new shift change practices.

Relationship Between Decreased Cortisol and Development of Chronic Pain in Traumatically Injured.

BACKGROUND: The relationship between pain and stress is widely accepted, yet the underlying neuroendocrine mechanisms are poorly understood. Cortisol secretion during a stress response, may distract attention from a painful stimulus, inhibiting pain. However, when pain is the stressor, cortisol secretion may intensify the pain experience and condition a fear-based memory of pain. This study attempts to determine the relationship between acute pain, chronic pain, and cortisol in the traumatically injured population. METHODS: Secondary analyses of a prospective observational study with participants from a Midwestern Adult Level I Trauma Center post traumatic injury, with interview and serum cortisol taken at hospitalization (baseline) and 6 mo after discharge, was completed using Ward's Method hierarchical cluster analysis, Pearson's correlations, and linear regressions. RESULTS: Two major clusters were identified. The Chronic Pain group were those who had severe pain at discharge and continued to have severe pain as defined by Numeric Pain Score. The Resolved Pain group were those who had moderate pain at discharge and their pain improved or resolved. Pain score at discharge significantly, negatively correlated with baseline cortisol levels (r = -0.142, P = 0.02). Minority status, single individuals, low cortisol at baseline, and greater psychological distress at baseline significantly increased the likelihood of developing chronic pain. CONCLUSIONS: Low cortisol and greater psychological stress, which are also associated with minority status and single individuals, contribute to chronic pain in the traumatically injured population. Trauma victims without an adequate cortisol response to acute injury and pain are at risk for development of chronic pain after injury.
