    Power of mentorship for recruitment and retainment of trauma staff

    by Diane Wintz, Kathryn Schaffer, Jennifer Hites, Laura Zgliniec, Miriah Boettcher

    Introduction: Healthcare teams throughout the nation noted workforce realignment during the COVID-19 pandemic, which impacted staff recruitment and retainment. The trauma team implemented a dedicated curriculum and multifaceted education in 2017 and amplified these efforts during the COVID-19 pandemic to ensure that nursing assistants assigned to trauma would continue to pursue their original career pathways. Methods: Mentorship recipients were HealthCare Partners (HCPs), employees at nursing-assistant level assigned to the trauma room during their shifts. HCPs with a minimum of 6 months of experience in the general emergency department (ED) were eligible for this position. Data regarding each HCP’s tenure as well as post-HCP career was tracked from 2017 to 2023 and reviewed to understand retainment. Results: There were 194 HCPs who worked in the ED full time during the 7 years. 90 HCPs were dedicated to trauma and received the trauma nursing curriculum (46%). More than 80% of the HCPs year-over-year retained their employment in the trauma position. Almost all HCPs (88/90; 98%) either went on to major healthcare or prehospital careers or continued to work in this same capacity in trauma to date. Conclusions: Recruitment and retainment are realistic if the opportunity matches the needs or incites motivation in the employee. We have designed an effective mentorship plan that accomplishes both goals and could be replicated in any healthcare system.

    An Abdominal Seat Belt Sign is Associated With Similar Incidence of Hollow Viscus Injury but Increased In-Hospital Mortality in Older Adult Trauma Patients: A PCSA Multicenter Study

    by Brittany G. Sullivan, Patrick T. Delaplain, Morgan Manasa, Erika Tay-Lasso, Walter L. Biffl, Kathryn B. Schaffer, Margaret Sundel, Samar Behdin, Mira Ghneim, Todd W. Costantini, et al.

    Background: The abdominal seat belt sign (SBS) is associated with an increased risk of hollow viscus injury (HVI). Older age is associated with worse outcomes in trauma patients. Thus, older trauma patients ≥65 years of age (OTPs) may be at an increased risk of HVI with abdominal SBS. Therefore, we hypothesized an increased incidence of HVI and mortality for OTPs vs younger trauma patients (YTPs) with abdominal SBS. Study Design: This post hoc analysis of a multi-institutional, prospective, observational study (8/2020-10/2021) included patients >18 years old with an abdominal SBS who underwent abdominal computed tomography (CT) imaging. Older trauma patients were compared to YTPs (18-64 years old) with bivariate analyses. Results: Of the 754 patients included in this study from nine level-1 trauma centers, there were 110 (14.6%) OTPs and 644 (85.4%) YTPs. Older trauma patients were older (mean 75.3 vs 35.8 years old, P < .01) and had a higher mean Injury Severity Score (10.8 vs 9.0, P = .02). However, YTPs had an increased abdominal abbreviated-injury scale score (2.01 vs 1.63, P = .02). On CT imaging, OTPs less commonly had intraabdominal free fluid (21.7% vs 11.9%, P = .02) despite a similar rate of abdominal soft tissue contusion ( P > .05). Older trauma patients also had a statistically similar rate of HVI vs YTPs (5.5% vs 9.8%, P = .15). Despite this, OTPs had increased mortality (5.5% vs 1.1%, P < .01) and length of stay (LOS) (5.9 vs 4.9 days P < .01). Conclusion: Despite a similar rate of HVI, OTPs with an abdominal SBS had an increased rate of mortality and LOS. This suggests the need for heightened vigilance when caring for OTPs with abdominal SBS.

    The Effect of 2019 Coronavirus Stay-at-Home Order on Geriatric Trauma Patients in Southern California

    by Morgan Manasa, Eric O Yeates, Areg Grigorian, Cristobal Barrios, Morgan Schellenberg, Natthida Owattanapanich, Galinos Barmparas, Daniel Margulies, Catherine Juillard, Kent Garber, et al.

    Background: California issued stay-at-home (SAH) orders to mitigate COVID-19 spread. Previous studies demonstrated a shift in mechanisms of injuries (MOIs) and decreased length of stay (LOS) for the general trauma population after SAH orders. This study aimed to evaluate the effects of SAH orders on geriatric trauma patients (GTPs), hypothesizing decreased motor vehicle collisions (MVCs) and LOS. Methods: A post-hoc analysis of GTPs (≥65 years old) from 11 level-I/II trauma centers was performed, stratifying patients into 3 groups: before SAH (1/1/2020-3/18/2020) (PRE), after SAH (3/19/2020-6/30/2020) (POST), and a historical control (3/19/2019-6/30/2019) (CONTROL). Bivariate comparisons were performed. Results: 5486 GTPs were included (PRE-1756; POST-1706; CONTROL-2024). POST had a decreased rate of MVCs (7.6% vs 10.6%, P = .001; vs 11.9%, P < .001) and pedestrian struck (3.4% vs 5.8%, P = .001; vs 5.2%, P = .006) compared with PRE and CONTROL. Other mechanisms of injury, LOS, mortality, and operations performed were similar between cohorts. However, POST had a lower rate of discharge to skilled nursing facility (SNF) (20% vs 24.5%, P = .001; and 20% vs 24.4%, P = .001). Conclusion: This retrospective multicenter study demonstrated lower rates of MVCs and pedestrian struck for GTPs, which may be explained by decreased population movement as a result of SAH orders. Contrary to previous studies on the generalized adult population, no differences in other MOIs and LOS were observed after SAH orders. However, there was a lower rate of discharge to SNF, which may be related to a lack of resources due to the COVID-19 pandemic, and thus potentially negatively impacted recovery of GTPs. Keywords

    Adolescent Trauma During the COVID Pandemic: Just Like Adults, Children, or Someone Else?

    by Perisa Ruhi-Williams, Eric O. Yeates, Areg Grigorian, Morgan Schellenberg, Natthida Owattanapanich, Galinos Barmparas, Daniel Margulies, Catherine Juillard, Kent Garber, Henry Cryer, et al.

    COVID-19 stay-at-home (SAH) orders were impactful on adolescence, when social interactions affect development. This has the potential to change adolescent trauma. A post-hoc multicenter retrospective analysis of adolescent (13-17 years-old) trauma patients (ATPs) at 11 trauma centers was performed. Patients were divided into 3 groups based on injury date: historical control (CONTROL:3/19/2019-6/30/2019, before SAH (PRE:1/1/2020-3/18/2020), and after SAH (POST:3/19/2020-6/30/2020). The POST group was compared to both PRE and CONTROL groups in separate analyses. 726 ATPs were identified across the 3 time periods. POST had a similar penetrating trauma rate compared to both PRE (15.8% vs 13.8%, P = .56) and CONTROL (15.8% vs 14.5%, P = .69). POST also had a similar rate of suicide attempts compared to both PRE (1.2% vs 1.5%, P = .83) and CONTROL (1.2% vs 2.1%, P = .43). However, POST had a higher rate of drug positivity compared to CONTROL (28.6% vs 20.6%, P = .032), but was similar in all other comparisons of alcohol and drugs to PRE and POST periods (all P > .05). Hence ATPs were affected differently than adults and children, as they had a similar rate of penetrating trauma, suicide attempts, and alcohol positivity after SAH orders. However, they had increased drug positivity compared to the CONTROL, but not PRE group.

    Effects of the COVID-19 pandemic on pediatric trauma in Southern California

    by Eric O. Yeates, Areg Grigorian, Morgan Schellenberg, Natthida Owattanapanich, Galinos Barmparas, Daniel Margulies, Catherine Juillard, Kent Garber, Henry Cryer, Areti Tillou, et al.

    Purpose: The COVID-19 pandemic resulted in increased penetrating trauma and decreased length of stay (LOS) amongst the adult trauma population, findings important for resource allocation. Studies regarding the pediatric trauma population are sparse and mostly single-center. This multicenter study examined pediatric trauma patients, hypothesizing increased penetrating trauma and decreased LOS after the 3/19/2020 stay-at-home (SAH) orders. Methods: A multicenter retrospective analysis of trauma patients ≤ 17 years old presenting to 11 centers in California was performed. Demographic data, injury characteristics, and outcomes were collected. Patients were divided into three groups based on injury date: 3/19/2019–6/30/2019 (CONTROL), 1/1/2020–3/18/2020 (PRE), 3/19/2020–6/30/2020 (POST). POST was compared to PRE and CONTROL in separate analyses. Results: 1677 patients were identified across all time periods (CONTROL: 631, PRE: 479, POST: 567). POST penetrating trauma rates were not significantly different compared to both PRE (11.3 vs. 9.0%, p = 0.219) and CONTROL (11.3 vs. 8.2%, p = 0.075), respectively. POST had a shorter mean LOS compared to PRE (2.4 vs. 3.3 days, p = 0.002) and CONTROL (2.4 vs. 3.4 days, p = 0.002). POST was also not significantly different than either group regarding intensive care unit (ICU) LOS, ventilator days, and mortality (all p > 0.05). Conclusions: This multicenter retrospective study demonstrated no difference in penetrating trauma rates among pediatric patients after SAH orders but did identify a shorter LOS.

    Self-inflicted injury and the older trauma patient: a 20 year review of suicide attempts and outcomes

    by Kathryn B. Schaffer, Tala Dandan, Dunya Bayat, Matthew R. Castelo, Summer H. Reames, Linda Hutkin-Slade, Walter L. Biffl

    Purpose: Older patients (Older) have complex health management needs often requiring additional resources. Mental health disorders are common among trauma patients, yet minimal information on older suicidal related injury and outcomes exists. A review of trauma patients with intentional self-inflicted injury at one trauma center was done to describe and identify unique elements of this cohort of patients. Methods: Trauma registry data from 2000 to 2019 were reviewed for intentional injury and data abstracted included demographics, injury severity, diagnoses, comorbidities and outcomes. Cohorts by age were compared: Older (65 +) vs Younger (< 65). Values considered significant at p ≤ 0.05. Results: 557 suicide attempts were identified with 9% among Older patients. Most patients were male with median age of 75 years for Older and 35 years for Younger cohort, with similar length of stay (LOS) and injury severity scores (ISS). Penetrating injury was more common among Older patients with firearm used most often, 34% vs 14% for Younger. Differences were evident between male and female Older patients with ISS 16.7 vs 5, p < 0.01 and mortality, p = 0.03. The outcome of discharge to home was significantly different between Older and Younger, 6% vs 20% (p < 0.05). A difference in mortality was evident, Older 38% vs Younger 18% (p < 0.05). Conclusion: With the growing aging population, it is important to acknowledge the resultant increase in concomitant mental health issues and suicidality among older patients, where depression may be undiagnosed and untreated. Providing care within this cohort may reduce future attempts and lessen the burden on the health care system.
