The 5Cs of Consultation: Training Medical Students to Communicate Effectively in the Emergency Department.

BACKGROUND: Effective communication is critical for health care professionals, particularly in the Emergency Department (ED). However, currently, there is no standardized consultation model that is consistently practiced by physicians or used for training medical graduates. Recently, the 5Cs of Consultation model (Contact, Communicate, Core Question, Collaborate, and Close the Loop) has been studied in Emergency Medicine residents using simulated consultation scenarios. OBJECTIVE: Using an experimental design, we aimed to evaluate the efficacy of the 5Cs consultation model in a novel learner population (medical students) and in a "real time and real world" clinical setting. METHODS: A prospective, randomized, controlled study was conducted at eight large, academic, urban, tertiary-care medical centers (U.S. and Canada). Intervention involved two experimental groups (asynchronous and live training) compared to a baseline control group. All participants placed up to four consult phone calls. A senior physician observed and assessed each call using a preapproved 5Cs checklist and a Global Rating Scale (GRS). RESULTS: Participants who received training (asynchronous or live) scored significantly higher on the 5Cs checklist total and GRS than the control group. Both training methods (asynchronous and live) were equally effective. Importantly, learning gains were sustained as students' 5Cs checklist total and GRS scores remained consistently higher at their second, third, and fourth consult (relative to their first consult). At posttest, all participants reported feeling more confident and competent in relaying patient information. CONCLUSION: Medical students can be trained to use the 5Cs model in a timely, inexpensive, and convenient manner and increase effectiveness of physician consultations originating from the ED.

Comparing diagnostic performance and the utility of clinical vignette-based assessment under testing conditions designed to encourage either automatic or analytic thought.

PURPOSE: Although decades of research have yielded considerable insight into physicians' clinical reasoning processes, assessing these processes remains challenging; thus, the authors sought to compare diagnostic performance and the utility of clinical vignette-based assessment under testing conditions designed to encourage either automatic or analytic thought. METHOD: This 2011-2012 multicenter randomized study of 393 clinicians (medical students, postgraduate trainees, and faculty) measured diagnostic accuracy on clinical vignettes under two conditions: one encouraged participants to give their first impression (FI), and the other led participants through a directed search (DS) for the correct diagnosis. The authors compared accuracy, feasibility, reliability, and relation to United States Medical Licensing Exam (USMLE) scores under each condition. RESULTS: A 2 (instructional condition) × 2 (vignette complexity) × 3 (experience level) analysis of variance revealed no difference in accuracy as a function of instructional condition (F[1,379] = 2.44, P = .12), but demonstrated the expected main effects of vignette complexity (F[1,379] = 965.2, P < .001) and experience (F[2,379] = 39.6, P < .001). Pearson correlations revealed greater associations between assessment scores and USMLE performance in the FI condition than in the DS condition (P < .001). Spearman-Brown calculations consistently indicated that alpha ≥ 0.75 could be achieved more efficiently under the FI condition relative to the DS condition. CONCLUSIONS: Instructions to trust one's first impres-sions result in similar performance when compared with instructions to consider clinical information in a systematic fashion, but have greater utility when used for the purposes of assessment.

Single-dose etomidate for intubation in the trauma patient.

BACKGROUND: Concerns over adrenal suppression caused by a single dose of etomidate for intubation led to limiting its use in trauma patients in 2006. OBJECTIVE: The purpose of this study was to compare mortality, hypotension, and intensive care unit (ICU) and hospital length of stay (LOS) for trauma patients requiring intubation during periods of liberal vs. limited etomidate use. METHODS: A retrospective review of trauma patients requiring emergent intubation who presented between August 2004 and December 2008, before and after we decided to limit the use of etomidate. Data were collected on patient demographics, induction agents used, episodes of hypotension in the first 24h, ICU and total hospital LOS, and survival. RESULTS: Of 1325 trauma patients intubated in the Emergency Department during the study period, 443 occurred during the 23 months before July 2006 (liberal etomidate use) and 882 in the 30 months after July 2006 (limited etomidate use). During the liberal use period, 258/443 (58%) were intubated using etomidate, compared to 205/882 (23%, p<0.0001) during the period of limited use. We found no significant differences in mortality (30% vs. 29%, p=0.70), mean ICU days (8.2 vs. 8.8, p=0.356), or mean hospital LOS (13.8 vs. 14.4 days, p=0.55). Episodes of hypotension were more common in the limited etomidate use group (45% vs. 33%, p<0.0001). CONCLUSIONS: A significant reduction in the use of etomidate in trauma patients was not associated with differences in mortality, ICU days, or hospital LOS, but was associated with an increase in episodes of hypotension within 24h of presentation.

Magnetic resonance imaging identifies occult hip fractures missed by 64-slice computed tomography.

BACKGROUND: Citing the enhanced resolution of 64-slice computed tomography (CT), some clinicians now use CT instead of magnetic resonance imaging (MRI) to detect occult hip fracture. OBJECTIVE: Our objective was to determine the incidence of occult hip fractures missed by 64-slice CT but detected by MRI. METHODS: We reviewed the medical records and radiology reports of patients over age 60 years with a hip fracture (acetabular, intertrochanteric, trochanteric, femoral neck, and femoral head) during a 3-year period, January 1, 2007 through December 31, 2009. We also reviewed all hip CT and MRI scans ordered during that period. Occult fractures were those visualized on CT or MRI but with negative plain films. We compared CT and MRI findings, and calculated percentages and 95% confidence intervals (CIs). RESULTS: Of 235 hip fractures, 211 were visible on initial plain films (90%, 95% CI 85-93%) and 24 (10%, 95% CI 6-15%) were occult. Eighteen occult fractures (7.6%, 95% CI 4.6-11.8%) were identified by CT (MRI not done), one (0.4%, 95% CI 0-2%) by MRI (CT not done), one (0.4%, 95% CI 0-2%) by both CT and MRI, and 4 patients (1.7%, 95% CI 0.5-4.3%) had a positive MRI but negative CT scan. CONCLUSION: Although 64-slice CT detected the majority of occult fractures, it missed four (2%) significant fractures detected by MRI. CT scan is helpful in the diagnosis of occult hip fracture, but one should not completely exclude the diagnosis based on a negative 64-slice CT scan in a patient with persistent, localized hip pain who cannot bear weight.
