A 32-year-old man presented to the hospital with a comminuted midshaft femoral fracture after a bicycle accident. Imaging suggested the fracture was pathologic and an open biopsy specimen was submitted to pathology for intraoperative consultation.
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.
A 50-year-old unhoused patient presented to the Emergency Department (ED) for evaluation of abdominal pain, reportedly one day after swallowing multiple sharp objects. Based on the radiologic finding of an open safety pin or paper clip in the distal stomach, he was appropriately scheduled for urgent esophagogastroduodenoscopy and ordered to remain NPO (nothing by mouth) to reduce the risk of aspirating gastric contents.
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.

Dr. Pascale Carayon, PhD, is a professor emerita in the Department of Industrial and Systems Engineering and the founding director of the Wisconsin Institute for Healthcare Systems Engineering (WIHSE). Dr. Nicole Werner, PhD, is an associate professor in the Department of Health and Wellness Design at the Indiana University School of Public Health-Bloomington. We spoke with both of them about the role of human factors engineering has in improving healthcare delivery and its role in patient safety.
A 49-year-old woman was referred by per primary care physician (PCP) to a gastroenterologist for recurrent bouts of abdominal pain, occasional vomiting, and diarrhea. Colonoscopy, esophagogastroduodenoscopy, and x-rays were interpreted as normal, and the patient was reassured that her symptoms should abate. The patient was seen by her PCP and visited the Emergency Department (ED) several times over the next six months. At each ED visit, the patient’s labs were normal and no imaging was performed.

Remle Crowe, PhD, NREMT, is the Director of Clinical and Operational Research at ESO. In her professional role, she provides strategic direction for the research mission of the organization, including oversight of a warehouse research data set of de-identified records (the ESO Data Collaborative). We spoke with her about how data is being used in the prehospital setting to improve patient safety.

After a breast mass was identified by a physician assistant during a routine visit, a 60-year-old woman received a diagnostic mammogram and ultrasound. The radiology assessment was challenging due to dense breast tissue and ultimately interpreted as “probably benign” findings. When the patient returned for follow-up 5 months later, the mass had increased in size and she was referred for a biopsy.
