ABSTRACT

The Area Deprivation Index (ADI) has been shown to be a determinant of healthcare outcomes in both medical and surgical fields, and is a measure of the socioeconomic status of patients. We sought to analyze outcomes in patients with upper extremity vascular injuries that were admitted over a five-year period to a Level I trauma center sorted by ADI. All patients with upper extremity vascular injury presenting to a level one trauma center between January 2013 and January 2017 were retrospectively collected. The patients were divided into two groups based on their ADI with the first group representing the lowest quartile of patients and the second group the higher three quartiles. Patient's demographics were analyzed as well as modes of trauma, hospital transfer status prior to receiving care, type of intervention received, follow-up rates and outcomes including both complication and amputation rates. Over this time period, a total of 88 patients with traumatic upper extremity vascular injuries were identified. The majority of injuries were due to penetrating trauma (74/88, 84%) with 41% (10/24) of patients in the lower ADI being victims of gunshot wounds compared to 27% (17/64) of those in the higher ADI (P = 0.19). Patients in the lowest ADI quartile were more likely to be African Americans (P= 0.0001), and more likely to be transferred to our university hospital prior to receiving care (P= 0.007). Arrival Glasgow Coma Scale and Injury Severity Score were similar as was time spent in the emergency room. Length of stay trended longer in the lowest ADI quartile as compared to the higher ADI (7.5 vs. 11.8, P= 0.59). The rates of long term follow-up were significantly lower in patients with the lowest ADI scores as opposed to the higher ADI group (P= 0.0098), however, there was no statistically significant difference in outcomes between the two groups including both complication and amputation rates. The ADI is associated with lower rates of long term follow-up after upper extremity vascular injuries, despite patients in both the high and low ADI groups having similar outcomes in regards to complication and amputation rates. Further study is warranted to investigate the role of the socioeconomic status in outcomes following traumatic injury.

ABSTRACT

CONTEXT: Illegal drug use and need for surgery are common in trauma. This allows examination of the effects of perioperative drug use. AIM: The aim was to study the effects of illegal drug use on perioperative complications in trauma. SETTING AND DESIGN: Propensity-matched analysis of perioperative complications between drug screen-positive (DSP) and drug screen-negative (DSN) patients from the National Trauma Data Bank (NTDB). METHODS: The NTDB reports drug screening as a composite. We compared complications for DSP, DSN, and specific chronic drug disorders. Time to first procedure was analyzed to determine whether delay to surgery was associated with reduced complications. STATISTICS: Logistic regression with 11 predictor variables was used to calculate propensity scores. Categorical and continuous variables were compared using Chi-square and Student's t-test, respectively. RESULTS: 752,343 patients (21.9%) were tested for illegal drugs. DSP was protective for mortality-relative risk (RR) 0.84 (P < 0.001) and arrhythmia RR 0.87 (P = 0.02). All complications (AC) were higher for DSP with a RR of 1.08 (P < 0.001). Cocaine, cannabis, and opioids were associated with reduced mortality. Cocaine was associated with increased myocardial infarction (MI). All four chronic drug disorders were associated with markedly higher arrhythmia. All except cannabis were associated with higher AC. Mortality was significantly lower for DSP for every time interval until first procedure. Continuous-time until procedure was associated with increased MI and arrhythmia. CONCLUSIONS: DSP was protective of mortality and cardiac complications. Drug disorders were protective for mortality but increased arrhythmia and AC. Delay until the surgery does not diminish cardiac or overall risk.

ABSTRACT

INTRODUCTION: Conservative management of penetrating renal trauma is emerging, with data originating from centers with variable level of trauma care. This study reviews the outcomes of renal salvage after penetrating trauma at a level I trauma center. MATERIALS AND METHODS: An institutional review board approved trauma registry at Saint Louis University Hospital was retrospectively analyzed, for patients with penetrating renal trauma from 2009 to 2014. Patients were divided into nephrectomy group (NG) or non-nephrectomy group (non-NG), and compared. A multi-variable analysis was performed to determine predictors of nephrectomy, with cross validation to evaluate the performance of the multi-variable model. Data was analyzed using R version 3.3.2. A p value of < 0.05 was considered as significant. RESULTS: A total of 121 patients were identified with penetrating renal trauma. Gunshot injury was the leading cause of injury (87%). Eighteen (15%) patients required nephrectomy. The overall mean injury severity score (ISS). was 20. High grade (grade 4-5) renal injuries were noted in 41 patients (34%). Among these, 14 patients (34%) underwent a nephrectomy, while 27 patients (66%) were managed conservatively to salvage renal units. CT grade of renal injury was the only predictor of nephrectomy, on multi-variable analysis (OR 17.09 CI 2.75-105.99, p = 0.002). CT grade of injury and injury severity score were predictors of endoscopic intervention on a sub group analysis of non-NG. CONCLUSIONS: CT grade of injury predicts nephrectomy after penetrating renal trauma. Conservative management is a feasible option in penetrating renal trauma even with a higher grade of injury.
