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

Appropriate follow-up of incidental abnormal radiological findings is an ongoing patient safety challenge. Inadequate follow-up can contribute to missed or delayed diagnosis, potentially resulting in poorer patient outcomes. This study describes implementation of an electronic health record-based referral system for patients with incidental radiologic finding in the emergency room. 

A 47-year-old man underwent a navigational bronchoscopy with transbronchial biospy under general anesthesia without complications. The patient was transferred to the post-acute care unit (PACU) for observation and a routine post-procedure chest x-ray (CXR). After the CXR was taken, the attending physician spoke to the patient and discussed his impressions, although he had not yet seen the CXR. He left the PACU without communicating with the bedside nurse, who was caring for other patients. The patient informed the nurse that the attending physician had no concerns.

This WebM&M highlights two cases of patient safety events that occurred due to medication dosing related to diagnostic imaging. The commentary highlights the challenges of administering sedation for diagnostic imaging, the use of risk stratification to understand patient risk for oversedation, and strategies for appropriate monitoring and communication.
