A Single Hospital-Wide Antibiogram is Insufficient to Account for Differences in Antibiotic Resistance Patterns Across Multiple ICUs.

BACKGROUND: Infection is a common cause of mortality within intensive care units (ICUs). Antibiotic resistance patterns and culture data are used to create antibiograms. Knowledge of antibiograms facilitates guiding empiric therapies and reduces mortality. Most major hospitals utilize data collection to create hospital-wide antibiograms. Previous studies have shown significant differences in susceptibility patterns between hospital wards and ICUs. We hypothesize that institutional or combined ICU antibiograms are inadequate to account for differences in susceptibility for patients in individual ICUs. METHODS: Culture and susceptibility data were reviewed over a 1-year period for 13 bacteria in the following ICUs: Surgical/Trauma, Medical, Neuroscience, Burn, and Emergency department. Antibiotic management decisions are made by individual teams. RESULTS: Nine species had sufficient data for inclusion into an All-ICU antibiogram. E coli and S aureus were the most common isolates. Seven species had significant differences in susceptibility patterns between ICUs. E cloacae showed higher rates of resistance to multiple antibiotics in the STICU than other ICUs. P aeruginosa susceptibility rates in the NSICU and BICU were 88% and 92%, respectively, compared to 60% and 55% in the STICU and MICU. Cephalosporins and Aztreonam had reduced efficacy against E coli in the NSICU, however remain effective in other ICUs. CONCLUSIONS: The results of this study show that different ICUs do have variability in antibiotic susceptibility patterns within a single hospital. While this only represents a single institution, it shows that the use of hospital-wide antibiograms is inadequate for creating empiric antibiotic protocols within individual ICUs.

Effects of the COVID-19 Pandemic on the Trauma Population in a Level 1 Trauma Center.

In this study, we evaluated the effects of the pandemic on our trauma population. We performed a retrospective review of the trauma registry in the 2 years prior, and then 2 years during the pandemic. We evaluated age, race, gender, injury severity score (ISS), mechanism of trauma, rate of self-inflicted injury, rate of gunshot wounds (GSW), presence of EtOH, drug screen results, mortality, rate of burn traumas, and zip code of residence. Our query captured 5 054 patients before, and 5 731 during the pandemic. We found no statistical difference in age, gender, mechanism of trauma, rate of self-inflicted injuries, and mortality during the pandemic when compared to before. There were statistically significant differences in race, ISS, rate of GSWs, EtOH use, drug screen results, and burn traumas. Geospatial mapping found a rise in GSWs for zip code 36606. Gun violence and substance use rose in our trauma population during COVID-19.

Identifying Radiographic and Clinical Indicators to Reduce the Occurrence of Nontherapeutic Laparotomy for Blunt Bowel and Mesenteric Injury.

BACKGROUND: Roughly 5% of patients with blunt abdominal trauma (BAT) have a blunt bowel and/or mesenteric injury (BBMI). Determining the need for operative management in these patients can be challenging when hemodynamically stable. Single center studies have proposed scoring systems based on CT findings to guide management. Our study aimed to determine the predictability of abdominopelvic CT scan (CT A/P) findings in conjunction with clinical exam to determine the necessity of operative intervention for BBMI. METHODS: Patients presenting from 2017 to 2022 to the University of South Alabama Level 1 Trauma Center after motor vehicle collision were retrospectively reviewed. Patients with CT findings suggestive of BBMI were further analyzed, noting CT findings, Glasgow coma scale (GCS), shock index, abdominal exam, operative or nonoperative management, and intraoperative intervention. RESULTS: 1098 patients with BAT underwent CT A/P. 139 patients had ≥1 finding suggestive of BBMI. 38 patients underwent surgical exploration and 30 had surgically confirmed BBMI. 27 patients required intervention for BBMI. Univariate analysis indicated that pneumoperitoneum (p < 0.0001), active extravasation of contrast (p = 0.0001), hemoperitoneum without solid organ injury (SOI) (p < 0.0001), peritonitis (p < 0.0001), and mesenteric stranding(p < 0.05) were significantly associated with intervention. CONCLUSION: In total, 30 patients had surgically confirmed BBMI. Active extravasation, pneumoperitoneum, hemoperitoneum without SOI, mesenteric stranding, and peritonitis were significant indicators of BBMI requiring intervention. CT and clinical findings cannot reliably predict the need for surgical intervention without ≥1 of these findings. Initial nonoperative management with serial clinical exams should be strongly considered to reduce incidence of nontherapeutic laparotomies.

Project Inspire pilot study: A hospital-led comprehensive intervention reduces gun violence among juveniles delinquent of gun crimes.

BACKGROUND: Gun violence disproportionately affects young Black men, but the impact extends to families and communities. Those at highest risk are teens delinquent of gun crimes. While there is no nationally accepted juvenile rate of recidivism, previous literature reveals rearrest rates from 50% to 80% in high-risk youth, and some reports show that up to 40% of delinquent juveniles are incarcerated in adult prisons before the age of 25 years. We hypothesize that Project Inspire, a hospital-led comprehensive intervention, reduces recidivism among high-risk teens. METHODS: Led by a level 1 trauma center, key community stakeholders including the juvenile court, city, and city police department joined forces to create a community-wide program aimed at curbing gun violence in high-risk individuals. Participants, aged 13 to 18 years, are selected by the juvenile gun court. They underwent a rigorous 3-week program with a curriculum incorporating the following: trauma-informed training and confidence building, educational/professional development, financial literacy, entrepreneurship, and career-specific job shadowing and mentorship. Rates of recidivism were measured annually. RESULTS: Project Inspire has hosted two classes in 2018 and 2019, graduating nine participants aged 14 to 17 years. Sixty-seven percent were Black. All were males. At 1 year, none of the graduates reoffended. At 2 years, one participant reoffended. At 3 years, no additional participants reoffended. No graduate reoffended as a juvenile. Thus, the overall rate of recidivism for Project Inspire is 11% to date. Eighty-nine percent of graduates received a diploma, general educational development, or obtained employment. CONCLUSION: Project Inspire is a hospital-led initiative that effectively reduces recidivism among juveniles delinquent of gun crimes. This sets the framework for trauma centers nationwide to lead in establishing impactful, comprehensive, gun-violence intervention strategies. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level V.

Blunt Cerebrovascular Injury (BCVI) Management: Is There a Right Answer?

Blunt cerebrovascular injury (BCVI) results from blunt trauma causing injury to the carotid and/or vertebral arteries. Its most severe manifestation is stroke. The purpose of this study was to evaluate the incidence, management, and outcomes of BCVI at a level one trauma/stroke center. Data on patients diagnosed with BCVI from 2016 to 2021 were extracted from the USA Health trauma registry with associated intervention performed and patient outcomes. Of the 97 patients identified, 16.5% presented with stroke-like symptoms (SS). Medical management was employed for 75%. Intravascular stent alone was utilized for 18.8%. The mean age of symptomatic BCVI patients was 37.6 with a mean injury severity score (ISS) of 38.2. Within the asymptomatic population, 58% received medical management and 3.7% underwent combination therapy. The mean age of asymptomatic BCVI patients was 46.9 with a mean ISS of 20.3. There were 6 mortalities, only one BCVI related.

Social Determinants of Health Impact Physical Recovery After Blunt Injury.

As defined by the United States Department of Health and Human Services, the Social Determinants of Health (SDOH) are conditions in the environment that affect health function and outcomes. The SDOH are divided into the following categories: economic stability, education access and quality, health care access and quality, neighborhood and built environment, and social and community content. It is known that SDOH impact long-term health outcomes. The influence that SDOH have on physical recovery after acute injury is less understood, however. In this study, patients who suffered a traumatic blunt injury completed a survey 12-14 months post-injury to assess their SDOH and physical health before and after their injury. The results showed that for the cohort of patients studied SDOH was the greatest predictor of long-term recovery, having a stronger correlation with recovery than injury severity score (ISS) or hospital length of stay (HLOS).

Overutilization of Helicopter Emergency Medical Services in Central Gulf Coast Region Results in Unnecessary Expenditure.

INTRODUCTION: When appropriately used, helicopter emergency medical services (HEMSs) allow for timely delivery of severely injured patients to definitive care. Inappropriate utilization of HEMSs results in increased cost to the patient and trauma system. The purpose of this study was to review current HEMS criteria in the central Gulf Coast region and evaluate for potential areas of triage refinement and cost savings. We hypothesized that a significant number of patients received potentially unwarranted HEMS transport. METHODS: A retrospective cohort study of all patients with trauma arriving to a level I trauma center by helicopter over 28 mo was performed; 381 patients with trauma and with HEMS transport from the scene were included. Data were collected from prehospital sources, as well as hospital chart review for each patient. The primary outcome was the rate of unwarranted HEMS transport. RESULTS: A total of 381 adult patients with trauma transported by the HEMS were analyzed, of which 34% were deemed potentially nonwarranted transports. The significant factors correlating with warranted HEMS transport included age, multiple long bone fractures, penetrating mechanism, and vehicle ejection. Insurance demographics did not correlate to transport modality. Many of these patients were transported from a location within the same county or the county adjacent to the trauma center. When comparing patients transported by ground and HEMSs from the same scene, no time savings were identified. Unwarranted transports at the trauma center represented an estimated health care expenditure of over $3 million. CONCLUSIONS: HEMSs may be overused in the central Gulf Coast region, creating the risk for a substantial resource and financial burden to the trauma system. Further collaboration is needed to establish HEMS triage criteria, that is, more appropriate use of resources.
