Mixed-methods process evaluation of a respiratory-culture diagnostic stewardship intervention.
The purpose of this study was to perform an evaluation of a diagnostic stewardship initiative for respiratory culture in the healthcare setting within a pediatric intensive care unit (PICU) in a tertiary-care center. The study found that the frequency of culture collection per day of service differed among attending physicians, ranging from 2.2 to 27 cultures per 100 days. A total of 14 interviews were conducted, and 87 clinicians (response rate: 47%) along with 77 nurses or respiratory therapists (response rate: 17%) participated in the survey. There was a variation in clinicians' stated practices concerning culture ordering, which was influenced by both their specialty and their perception of the respiratory culture's usefulness. Additionally, group "default" practices, fear, and hierarchy affected the decision to order cultures. Obstacles to standardization encompassed concerns about missing a diagnosis and the conflict between standardized practices and individual judgment.
