A Mixed Methods Study Exploring Patient Safety Culture at Four VHA Hospitals.

Background: Patient safety culture (PSC) fosters an environment of trust where people are encouraged to share information to promote psychological safety. To measure PSC, the Veteran's Health Administration (VHA) developed a PSC survey consisting of 20 items administered to all VHA employees. The survey comprises four scales: (1) risk identification and Just Culture, (2) error transparency and mitigation, (3) supervisor communication and trust, and (4) team cohesion and engagement. Our objective was to compare the PSC survey data to qualitative data regarding high reliability organization (HRO) implementation from four purposively selected VHA hospitals to assess how it manifests and converges.

Methods: Qualitative data focused on understanding HRO implementation efforts were collected from key informants between 2019 and 2020 at 4 of the 18 VHA HRO implementation hospitals. To explore the extent and manifestation of each of the PSC scales among the 4 sites, we combined the qualitative data with the PSC survey data from each hospital using a joint display.

Results: Survey responses were significantly different between the 4 hospitals for all 4 PSC scales. Of the 20 PSC survey items, 12 (60.0%) significantly differed across the 4 hospitals. For example, we saw cross-hospital differences in the following survey items: "We are given feedback about changes put into place based on event reports" and "We take the time to identify and assess risks to patient safety." Qualitative data supported manifestations for 80.0% (16/20) of PSC individual survey items among hospitals.

Conclusion: The authors found that the qualitative data manifestations were well aligned with the VHA PSC scales, but relationships were not always consistent between data sources. Further research is necessary to elucidate these relationships.
