Root cause analysis to identify major barriers to the promotion of patient safety in Japan

Abstract

Objectives Despite existing patient safety measures, both outside and inside hospitals, barriers to patient safety prevail. We aimed to identify the current contributory factors to patient safety in Japan. Methods This qualitative study included nine expert Japanese health care providers working both inside and outside hospitals. These participants, who included six physicians, one nurse, one pharmacist, and one physical therapist, work across a broad spectrum in government policy and public health, academia, and safety management. Root cause analysis using the online Kawakita Jiro method (KJ method or affinity diagram) was conducted. We labeled and summarized the classification in a fishbone diagram to elucidate barriers to patient safety in Japan. Results We identified specific factors in six main groups: the hospital system, education, law and policy, culture and society, patient centricity, and multidisciplinary cooperation. Quality of care, patient engagement, and shortage of patient safety specialists were crucial factors for multiple groups. Conclusions This study clarifies components of patient safety in Japan and provides basic data for promoting comprehensive patient safety in the future. Periodic root cause analysis of comprehensive patient safety issues can help develop strategies to promote patient safety at both the hospital and national levels.
