A 42-year-old man with a history of posttraumatic stress disorder (PTSD), alcohol use disorder and anxiety disorder, was seen in the emergency department (ED) after a high-risk suicide attempt by hanging. The patient was agitated and attempted to escape from the ED while on an involuntary psychiatric commitment. The ED staff treated him as a “routine boarder” awaiting an inpatient bed, with insufficiently robust behavioral monitoring.

This case describes an older adult patient with generalized abdominal pain who was eventually diagnosed with inoperable bowel necrosis. Although she appeared well and had stable vital signs, triage was delayed due to emergency department (ED) crowding, which is usually a result of hospital crowding. She was under-triaged and waited three hours before any diagnostic studies or interventions commenced. Once she was placed on a hallway gurney laboratory and imaging studies proceeded hastily.

This piece discusses virtual nursing, an approach to care that incorporates an advanced practice nurse into hospital-based patient care through telehealth. Virtual nursing increases patient safety and may enable expert nurses to continue to meet patient needs in future staffing shortages.

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.

Human factors engineering or ergonomics (HFE) is a scientific discipline broadly focused on interactions among humans and other elements of a system.
