Effectiveness of Doctor Clerks Supporting Physicians' Work in Japan: A Systematic Review

The burgeoning administrative workload on physicians in Japan's healthcare system has necessitated innovative approaches to optimize clinical care. Integrating doctor clerks, tasked with administrative and clerical duties, has emerged as a potential solution to alleviate this burden. This systematic review aims to evaluate the effectiveness of doctor clerks in improving physicians' working conditions and patient care quality. A comprehensive literature search was conducted using Ichushi Web and Google Scholar from January 2000 to September 2023. Data were extracted on publication year, study setting, department focus, work scope, and outcomes of doctor clerk implementation. The search identified 3570 studies, with 17 meeting the inclusion criteria. Most studies were performed in general hospitals with 76.5% (13/17). The studies regarding university hospitals were 17.6% (3/17). Only one study was performed in a community hospital with 5.9% (1/17). More than half of doctor clerks worked not explicitly allocated to one department and did their work not specific to one department with 52.9% (9/17). Three studies report that doctor clerks collaborate with orthopedic surgeons. Two studies report that doctor clerks collaborate with emergency medicine physicians. Each study reports that doctor clerks collaborate with respiratory or general medicine. The most frequent is document support, with 94.1% (16/17). The second most frequent working content is consultation support, with 47.1% (8/17). The third most frequently working content is ordering support, with 23.5% (4/17). Call response, secretary work, education support, research support, conference support, and other professional support are included, each with 5.9% (1/17). Regarding clinical outcomes, five studies assessed a reduction in physician paperwork time (29.4%). Four studies assessed the frequency of the contents of doctor clerks' work (23.5%). Four studies assessed the positive perception of physicians (23.5%). Four studies assessed the amount of the reduction in physicians' overtime work (23.5%). Three studies assess the amount of the reduction in hospital costs (17.6%). One study assessed part-time physicians' fatigue reduction (5.9%). Each study assessed the quality of patient care, such as doctor's clerk education for standardization, increase in the number of patients accepted, reduction in medical incidents, decrease in patient waiting time, and primary to tertiary prevention. Introducing doctor clerks in Japan's healthcare system shows promise in enhancing physicians' working conditions and potentially improving patient care. However, conclusive evidence on the impact on patient care quality necessitates further investigation, serving as a foundation for future policy and healthcare system optimization.
