Importance of the Emergency Medicine Application Components: The Medical Student Perception.

BACKGROUND: The National Resident Matching Program (NRMP) application has several elements. With limited time and resources, students must prioritize the key application elements on which to focus. It is unclear if medical students applying to emergency medicine (EM) prioritize the same items as program directors. OBJECTIVE: We sought to determine medical student perception of the importance of each factor of the NRMP application to an EM residency. METHODS: This was a cross-sectional study approved by the Institutional Review Board at an academic tertiary care Level I trauma center. A pilot-tested and validated survey tool was given to all medical students rotating in EM during an 18-month period. The students ranked each application item on a 5-point scale (1 = not important and 5 = very important) with verbal anchors. RESULTS: Of 136 medical students, 85.3% responded. Excluded were 31% who were not planning to apply to EM, leaving 80 responses for analysis. Items ranked higher were EM rotation grade, interview, clinical rotation grades, and letters of recommendation. Less emphasis was placed on Alpha Omega Alpha (AOA) honor society status, publication in medical literature, and personal statement. Items most agreed upon and believed to be most important by the students were EM rotation grade, interviews, and clinical rotation grades. CONCLUSIONS: This is similar to previously reported rankings by program directors. Although medical students agreed on the importance of most aspects of the NRMP application, areas of discordance included emphasis on extracurricular activities and AOA. This can have implications for medical student mentoring and advising.

Rural Trauma Team Development Course Positively Impacts its Desired Objectives.

BACKGROUND: The Rural Trauma Team Development Course (RTTDC) is designed to help rural hospitals better organize and manage trauma patients with limited resources. Although RTTDC is well-established, limited literature exists regarding improvement in the overall objectives for which the course was designed. The aim of this study was to analyze the goals of RTTDC, hypothesizing improvements in course objectives after course completion. METHODS: This was a prospective, observational study from 2015 through 2021. All hospitals completing the RTTDC led by our Level 1, academic trauma hospital were included. Our institutional database was queried for individual patient data. Cohorts were delineated before and after RTTDC was provided to the rural hospital. Basic demographics were obtained. Outcomes of interest included: Emergency Department (ED) dwell time, decision time to transfer, number of total images/computed tomography scans obtained, and mortality. Chi square and non-parametric median test were used. Significance was set at P < .05. RESULTS: Sixteen rural hospitals were included with a total of 472 patients transferred (240 before and 232 after). Patient demographics were similar before and after RTTDC. ED dwell time was significantly reduced by 64 min (P = .003) and decision to transfer time was cut by 62 min (P = .004) after RTTDC. Mean total radiographic images and CT scans were significantly reduced (P < .001 and P = .002, respectively) after RTTDC. Mortality was unaffected by RTTDC completion (P = .941). CONCLUSION: The RTTDC demonstrates decreased ED dwell time, decision time to transfer, and number of radiographic images obtained prior to transfer. More rural hospitals should be offered this course.

Duration of Antibiotic Therapy in Necrotizing Soft Tissue Infections: Shorter is Safe.

Background: Early debridement improves outcome in necrotizing soft tissue infection (NSTI), but there is no consensus on duration of antimicrobial therapy. We recently changed practice to discontinue antibiotic agents early with a goal of 48 hours after adequate source control. We hypothesized that discontinuing antibiotic agents after a short course is safe in the treatment of NSTI. Patients and Methods: This was a prospective study of patients with NSTI comparing short duration of antibiotic agents to a control population after a change in practice. In 2018 we began discontinuing antibiotic agents within 48 hours of source control (absence of cellulitis and no evidence of active infection). Previously, antibiotic duration was at the discretion of the attending surgeon (generally 7-10 days). Patients were excluded from analysis if they were initially debrided at a referring facility, immune compromised, or died prior to source control. Patient characteristics and outcomes were evaluated. The primary outcome was treatment failure requiring antibiotic agents to be restarted with or without further debridement of infected tissue. Secondary outcomes included the duration of antibiotic therapy after source control. Results: We evaluated 151 patients; 119 admitted between January 1, 2011 and January 31, 2018 (PRE) and 32 admitted after January 31, 2018 (POST). Patients were not statistically different regarding characteristics, admission physiologic variables, and comorbidities. The median duration of antibiotic agents after source control in the PRE group was 180.3 hours (interquartile range [IQR], 100.7-318.8) versus 48 hours (IQR, 32.3-100.8) in the POST group (p < 0.01). Patients in each group were treated as described above, and treatment failure occurred in seven (5.9%) PRE patients and two (6.3%) POST (99.3% post hoc power at non-inferiority limit 20%, significance p < 0.05). Thirty-day all-cause mortality was not different between groups (6.7% vs. 6.3%; p = 0.94). Conclusions: Short-duration (48 hours) antibiotic agents after NSTI source control is as safe and effective as a longer course.

Focusing in on gallbladder disease. Do current imaging modalities accurately depict the severity of final pathology?

BACKGROUND: Accuracy of imaging modalities for gallbladder disease(GBD) remains questionable. We hypothesize ultrasonography(US), computed tomography(CT), and magnetic resonance imaging(MRI) poorly correlate with final pathologic analysis. METHODS: This was a retrospective review of all patients who underwent cholecystectomy at our institution. Primary outcome was agreement between US, CT, and MRI, and final pathology report of the gallbladder. Cohen's Kappa statistic was used to describe the level of agreement (0 = agreement equivalent to chance, 0.1-0.2 = slight agreement, 0.21-0.40 = minimal/fair agreement, 0.41-0.60 = moderate agreement, 0.61-0.80 = substantial agreement, 0.81-0.99 = near perfect agreement, 1 = perfect agreement). Significance was set at p < 0.05. RESULTS: 1107 patients were enrolled. Average age was 48.6(±17.6); 64.2% were female. There was minimal agreement between the three imaging modalities and final pathology (US = 0.363; CT = 0.223; MRI = 0.351;p < 0.001). CONCLUSION: Poor agreement exists between imaging modalities and final pathology report for GBD. Urgent surgical intervention for patients presenting with symptoms of GBD should be considered, despite imaging results.

Successful Non-Operative Management of Adhesive Small Bowel Obstruction: Is it Really a Success?

BACKGROUND: In adhesive small bowel obstructions (ASBOs), literature has shown that passage of a water-soluble contrast challenge at either 8 hours or 24 hours is predictive of successful non-operative management (NOM) for an ASBO, but the long-term outcomes between these two groups are unknown. We hypothesized that patients who require longer transit times to the colon have a higher one-year recidivism of ASBO. METHODS: This was a 4-year review of patients with presumed ASBO undergoing successful NOM. Those requiring operation or those with an SBO due to something other than adhesions were excluded. Patients were divided into two groups (8 hour and 24 hour) based on when contrast reached their right colon. Patients were followed for one year to determine ASBO recurrence. RESULTS: 137 patients underwent NOM; 112 in the 8-hour group and 25 in the 24-hour group. One-year recurrence rate was 21.4% in the 8-hour group and 40% in the 24-hour group (P = 0.05). The median time to recurrence was 113 days in the 8-hour group and 13 days in the 24-hour group (P = 0.02). Of those who recurred in the 24-hour group, 60% recurred within 30 days (P = 0.01). On univariable analysis, first-time ASBO and 24-hour transit time were risk factors for recurrence. CONCLUSIONS: Adhesive small bowel obstruction patients undergoing NOM in the 24-hour group had a recurrence rate nearly twice that of patients in the 8-hour group and may benefit from an operative exploration during the index hospitalization at the 8-hour mark of a water-soluble contrast challenge, especially if experiencing a first-time ASBO.
