The evolving relationship between hospitals and physicians has become a focal point for healthcare managers and researchers, particularly as the healthcare system undergoes a revamp with quality at its core. While hospital-physician integration holds promise as a solution to the challenges faced by hospitals, its effects have been mixed. This study conducts econometric analyses using patient-visit-level data for cardiac surgery in Florida, USA, and adopts an activity-based measure of integration (ABI) to investigate the relationship between integration and clinical care outcomes, such as patient mortality risk, length of stay (LOS) performance, and 30-day readmission risk. This study contributes to the literature by proposing a non-linear relationship between exposure to different levels of ABI and clinical care outcomes. Further, this study suggests that a moderate level of integration could be desirable and provides implications for administrators evaluating their hospital's physician integration initiatives.
