Background: Japanese physician training programs are currently not subject to rigorous national standardization. Despite residency restructuring in 2004, little is known about the current work allocation of residents in Japan.
Aims: We quantified the amount of time that Japanese junior residents spend in service versus education in the context of caseload, fatigue, and low-value administrative work.
Methods: In this prospective, time-and-motion study, the activity of 1st- and 2nd-year residents at three Japanese community hospitals was observed at 5-min intervals over 1 week, and categorized as patient care, academic, non-patient care, and personal. Self-reported sleep data and caseload information were simultaneously collected. Data were subanalyzed by gender, training level, hospital, and shift.
Results: A total of 64 participating residents spent substantially more time in patient care activities than education (59.5% vs. 6.8%), and little time on low-value, non-patient work (5.1%). Residents reported a median 5 h of sleep before shifts and excessive sleepiness (median Epworth score, 12). Large variations in caseload were reported (median 10 patients, range 0-60).
Conclusions: New physicians in Japan deliver a large volume of high-value patient care, while receiving little structured education and enduring substantial sleep deprivation. In programs without work-hour restrictions, caseload limits may improve safety and quality.
