Beyond night float? The impact of call structure on internal medicine residents

Limitation of resident working hours has been a critical issue for training programs in recent years. At Providence Medical Center, residents and faculty collaborated in developing goals, implementation strategies, and an evaluation process for a new ward float system. The goals of the float system were to reduce fatigue, facilitate education, maintain continuity of care, and minimize the negative impact of training on residents' personal lives. Evaluation revealed: 1) 74% of the residents preferred Providence Medical Center float system (PMCF) to either night float (NF) (13%) or standard every-fourth-night call (EFNC) (13%); and 2) PMCF was perceived to ensure quality patient care to a greater degree than was NF, to better facilitate resident education than was NF, and to have a less negative impact on personal lives than was EFNC.
