Impact of a physician-in-triage process on resident education.

introductionEmergency department (ED) crowding negatively impacts patient care quality and efficiency. To reduce crowding many EDs use a physician-in-triage (PIT) process. However, few studies have evaluated the effect of a PIT processes on resident education. Our objective was to determine the impact of a PIT process implementation on resident education within the ED of an academic medical center.

methodsWe performed a prospective cross-sectional study for a 10-week period from March to June 2011, during operationally historic trended peak patient volume and arrival periods. Emergency medicine residents (three-year program) and faculty, blinded to the research objectives, were asked to evaluate the educational quality of each shift using a 5-point Likert scale. Residents and faculty also completed a questionnaire at the end of the study period assessing the perceived impact of the PIT process on resident education, patient care, satisfaction, and throughput. We compared resident and attending data using Mann-Whitney U tests.

resultsDuring the study period, 54 residents and attendings worked clinically during the PIT process with 78% completing questionnaires related to the study. Attendings and residents indicated "no impact" of the PIT process on resident education [median Likert score of 3.0, inter-quartile range (IQR): 2-4]. There was no difference in attending and resident perceptions (p-value =0.18). Both groups perceived patient satisfaction to be "positively impacted" [4.0, IQR:2-4 for attendings vs 4.0, IQR:1-5 for residents, p-value =0.75]. Residents perceived more improvement in patient throughput to than attendings [3.5, IQR:3-4 for attendings vs 4.0, IQR:3-5 for residents, p-value =0.006]. Perceived impact on differential diagnosis generation was negative in both groups [2.0, IQR:1-3 vs 2.5, IQR:1-5, p-value = 0.42]. The impact of PIT on selection of diagnostic studies and medical decision making was negative for attendings and neutral for residents: [(2.0, IQR:1-3 vs 3.0, IQR:1-4, p-value =0.10) and (2.0, IQR:1-4 vs 3.0, IQR:1-5, p-value =0.14 respectively].

conclusionImplementation of a PIT process at an academic medical center was not associated with a negative (or positive) perceived impact on resident education. However, attendings and residents felt that differential diagnosis development was negatively impacted. Attendings also felt diagnostic test selection and medical decision-making learning were negatively impacted by the PIT process.
