As patients with safety concerns frequently report the concerns to their nurse, nurses' responses must be consistent across patients and free from bias. In this vignette study, nurses were presented with hypothetical patient complaints with varying combinations of patient demographics (e.g., race), complaint type (e.g., communication), and patient communication approach (e.g., confrontational). Nurses were asked to rate the credibility of the complaint, their level of concern, and intention to report the complaint to their incident reporting system. Results varied by patient and nurse characteristics.
