A mixed methods study exploring patient safety culture at 4 VHA Hospitals.

In 2019, the Veterans Health Administration (VHA) implemented a high reliability organization (HRO) strategy to improve care delivery and patient safety. This mixed methods study compared qualitative data from key informants at four VHA sites with quantitative data from a large patient safety culture (PSC) survey of VHA employees across two years. The researchers found that qualitative data aligned with most PSC survey domains but identified significant variation across sites.
