OBJECTIVE: Describe the development and implementation of a theory-informed professional practice model (PPM) and examine associated workforce, quality, engagement, and financial outcomes. BACKGROUND: Healthcare organizations face persistent challenges related to workforce turnover, disengagement, and fragmented care delivery. PPMs align nursing practice, leadership, and outcomes, but are often insufficiently operationalized. METHODS: This evidence-based practice QI initiative implemented a PPM grounded in Convergent Care Theory using a structured, multiphase clinical inquiry infrastructure. Aggregated organizational data were analyzed to assess workforce, patient quality and safety, staff engagement, and conservative cost avoidance. RESULTS: More than 2500 nurses engaged in system-wide inquiry and strategic planning. One-year RN turnover decreased from 22.14% to 10.42% (P=0.002), associated with an estimated $4.6 million in conservative cost avoidance. Catheter-associated urinary tract infection rates decreased by 48%, and Leapfrog Hospital Safety Grades improved. CONCLUSIONS: Operationalizing theory through a system-wide PPM improved workforce retention, patient outcomes, engagement, and organizational cost avoidance.
