Background Because residents are often on the frontlines of patient care and are likely to witness adverse events firsthand, it is critical they report patient safety events. They may, however, be underreporting. Objective We examined the current literature to identify strategies to increase patient safety event reporting by residents. Methods We used CINAHL (EBSCO Information Services, Ipswich, MA), EMBASE (Elsevier, Amsterdam, the Netherlands), PsycINFO (APA Publishing, Washington, DC), and PubMed (National Center for Biotechnology Information, Bethesda, MD) databases. The search was limited to English-language articles published in peer-reviewed journals through March 2020. Key terms included “residents, trainees, fellows, interns, graduate medical education, house staff, event reporting, patient safety reporting, incident reporting, adverse event, and medical error.” To organize findings, we adapted a published framework of strategies for encouraging self-protective behavior. Results We identified 68 articles that described strategies used to increase event reporting. The most sustainable interventions used a combination of 3 of the 5 strategies: behavior modeling, surveys and messaging, and required limited financial support. The survey creates awareness; the behavior modeling is critical for educational purposes, and the reminders help to reinforce the new behavior and embed it into routine patient care activities. We noted a dearth of studies involving trainees in root cause analysis following submission of event reports. Conclusions The most successful sustainable interventions were those that combined strategies that minimized time for busy physicians, incorporated accessible event reporting in already existing medical records, and became part of a normal workflow in patient care.
