Given the high number of errors and negative events committed within medical settings, the emphasis on patient safety culture is becoming more prevalent. Despite this effort, underreporting has been and continues to be an issue in this area. Some research has shown a link between underreporting and lack of management responsiveness, but more work is necessary to identify reasons for underreporting and potential mitigating solutions. The objective of the present research is to answer questions regarding the impact supervisors have on staff’s patient safety perceptions and event reporting, through the use of archival survey data collected with the AHRQ Hospital Safety Culture Survey (2004). Probable moderators and mediators of key relationships were explored as well. Results are presented and their implications are discussed herein.
