Throughout 2022, AHRQ PSNet has shared research that elucidates the complex nature of misdiagnosis and diagnostic safety. This Year in Review explores recent work in diagnostic safety and ways that greater safety may be promoted using tools developed to improve diagnostic practices.

This Spotlight Case describes an older man incidentally diagnosed with prostate cancer, with metastases to the bone. He was seen in clinic one month after that discharge, without family present, and scheduled for outpatient biopsy. He showed up to the biopsy without adequate preparation and so it was rescheduled. He did not show up to the following four oncology appointments.

The Patient Safe-D(ischarge) program used standardized tools to educate patients about their discharge needs, test understanding of those needs, and improve medication reconciliation at admission and discharge. A quasi-randomized controlled trial of the program found that it significantly increased patients' understanding and knowledge of their diagnoses, treatment, and required follow-up care.
