Using the IOM definition of diagnostic error, this study interviewed hospitalized adults to characterize their experiences with diagnostic errors and their perspectives on causes, impacts and prevention strategies. Nearly 40% of patients interviewed reported at least one diagnostic error in the past 5 years that adversely impacted their emotional and physical well-being. Qualitative analysis revealed five main themes underlying the causes of diagnostic error: problems with clinical evaluation, limited time with clinicians, poor communication between clinicians and patients or between clinicians, and systems failures. Suggested strategies to reduce diagnostic error included improvements to clinical management, increase patient access to clinicians, communication improvements between patients and clinicians and between clinicians, and self-advocacy by patients.

Research has suggested that health care providers’ emotions may impact patient safety. These authors conducted 86 semi-structured interviews with emergency department (ED) nurses and physicians to better understand their emotional triggers, beliefs about emotional influences on patient safety, and emotional management strategies. Patients often triggered both positive and negative emotions; hospital- or systems-level factors primarily triggered negative emotions. Providers were aware that negative emotions can adversely impact clinical decision-making and place patients at risk; future research should explore whether emotional regulation strategies can mitigate these safety risks.

This retrospective cohort study used root cause analysis (RCA) to examine safety reports from emergency departments at Veterans Health Administration hospitals over a two-year period. Of the 144 cases identified, the majority involved delays in care (26%), elopements (15%), suicide attempts and deaths (10%), inappropriate discharges (10%) and errors following procedures (10%). RCA revealed that primary contributory factors leading to adverse events were knowledge/educational deficits (11%) and policies/procedures that were either inadequate (11%) or lacking standardization (10%).
