This observational field study attempted to quantify the objective task load imposed on emergency department (ED) providers, determine the degree of subjective workload they experience, and to correlate these data with ED operational metrics, mainly ED crowding metrics. Participants were a convenience sample of 10 emergency care providers; the 3 female and 7 male participants represented a variety of provider levels (6 physicians, 3 physician assistants, and 1 nurse practitioner). Forty-two hours of data were collected. ED variables were obtained from the hospital's existing information system each hour and included the Emergency Severity Index (ESI), number of people in the waiting room, patient/doctor ratio, patient/nurse ratio, number of patients assigned, number of providers on duty and crowding variables; Emergency Department Work Index (EDWIN) and occupancy level. Providers were shadowed and observed each hour by a researcher who recorded the type of tasks they performed, the number of tasks they performed, the time they spent on each task and the number of times they were interrupted. Subjective workload ratings (NASA-TLX) were obtained from providers at the end of each hour of observation. Correlations were performed to evaluate the relation of observed...
