A 56-year-old woman presented to the emergency department (ED) with shaking, weakness, poor oral intake and weight loss, constipation for several days, subjective fevers at home, and mild pain in the chest, back and abdomen. An abdominal x-ray confirmed a large amount of stool in the colon with no free air and her blood leukocyte count was 11,500 cells/μL with 31% bands. She received intravenous fluids but without any fecal output while in the ED.

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.

In the past several decades, technological advances have opened new possibilities for improving patient safety. Using technology to digitize healthcare processes has the potential to increase standardization and efficiency of clinical workflows and to reduce errors and cost across all healthcare settings.¹ However, if technological approaches are designed or implemented poorly, the burden on clinicians can increase. For example, overburdened clinicians can experience alert fatigue and fail to respond to notifications. This can lead to more medical errors.
