Verbal or physical violence towards healthcare workers can result in harm of both staff and patients. Based on semi-structured interviews with 25 registered nurses working in the emergency department (ED) at one large academic health system, the authors explored nursing perspectives on how EHR-based behavioral flags – used to identify incidents of workplace violence – can promote clinician safety. Participants identified benefits of the flags as well as concerns (e.g., introduction of bias, potential damage to the patient-clinician relationship), highlighted necessary system improvements, and how related challenges in the ED (e.g., unmet mental health needs of patients, COVID-19-related burnout) can contribute to workplace violence.
