Sensitivity of a bedside reagent strip for the detection of spontaneous bacterial peritonitis in ED patients with ascites.

STUDY OBJECTIVE: To determine the sensitivity of a highly sensitive bedside leukocyte esterase reagent strip (RS) for detection of spontaneous bacterial peritonitis (SBP) in emergency department (ED) ascites patients undergoing paracentesis. METHODS: We conducted a prospective, observational cohort study of ED ascites patients undergoing paracentesis at two academic facilities. Two practitioners, blinded to each other's results, did a bedside RS analysis of the peritoneal fluid in each patient and documented the RS reading at 3-min according to manufacturer-specified colorimetric strip reading as either "negative", "trace", "small", or "large". The primary outcome measure was sensitivity of the RS strip for SBP (absolute neutrophil count ≥ 250 cells/mm3) at the "trace" threshold (positive equals trace or greater). RESULTS: There were 330 cases enrolled, with 635 fluid analyses performed. Of these, 40 fluid samples had SBP (6%). Bedside RS had a sensitivity, specificity, positive predictive value, and negative predictive value of 95% (95% CI 82%-99%), 48% (95% CI 44%-52%), 11% (95% CI 10%-11%), and 99% (95% CI 97%-99%) respectively at the "trace" threshold for the detection of SBP. CONCLUSION: Bedside use of the RS in ED ascites patients demonstrated high sensitivity for SBP. Given the wide confidence intervals, we cannot currently recommend it as a stand-alone test. We recommend further study with a larger number of SBP patients, potentially combining a negative RS result with low clinical suspicion to effectively rule out SBP without formal laboratory analysis.

Virtual Reality as an Interview Technique in Evaluation of Emergency Medicine Applicants.

NEED FOR INNOVATION: Current interviewing strategies and the standardized letter of evaluation may not provide enough insight into preferred resident characteristics. Emergency medicine (EM) residency programs are challenged with identifying trainees who can problem solve, communicate, and work well with fellow health professionals. BACKGROUND: Structured interviews have previously been used and can help predict success but candidates have reported a negative impression with their use. OBJECTIVE OF INNOVATION: This structured virtual reality (VR) interviewing method was designed so that interviewers can observe the communication abilities, subtle personality traits, and teamwork skills of applicants interviewed at an EM residency program. DEVELOPMENT PROCESS: A consumer VR headset became available and in combination with an interactive team game was incorporated into a standardized team-based interview session. This session was designed to allow observation of candidates' communication, problem solving, and teamwork skills. IMPLEMENTATION PHASE: Surveys were collected to examine the satisfaction of EM residency applicants who participated in this novel standardized interviewing method using a VR headset. After the submission of rank lists, but prior to Match Day, those who interviewed were e-mailed a voluntary, anonymous, and confidential survey asking about their interview experience, specifically about the VR portion. The survey was sent to 102 applicants with 63 responses for a 62% response rate at the completion of the 2015 to 2016 interview season. OUTCOMES: Overall study findings suggested that participants had a highly favorable impression of the VR portion of the interview. Specifically, participants reported that this interview technique was appropriate and worthwhile. Additionally, participants attested that the Oculus portion of the interview gave insight to their work ethic, personality, and communication skills and how they work with others. REFLECTIVE DISCUSSION: The novel interviewing method used in this study allowed interviewers to gain insight beyond that of the paperwork and brief face-to-face interaction. Study findings suggest that interviewees accepted the use of this novel interview method. It has been incorporated into our interview process for three consecutive years.
