註釋One key driver of improvement in surgical outcomes is a surgeon's prior experience. However, research notes that not all experience provides equal value for performance. How then should surgeons accumulate experience to improve quality outcomes? In this paper we investigate the differential effects of focal and related (i.e., tasks similar to, but not identical to, the focal task) experience. We open up the black box of the volume-outcome relationship by going beyond just dividing experience into focal and related categories, but also considering how sub-tasks, and context (i.e., the organization in which the work takes place) affect performance. To understand these issues, we assemble a novel data set on 71 cardiothoracic surgeons who performed over 6,500 procedures during a period of 10 years since the introduction of a breakthrough surgical procedure. We find that as compared to related experience, surgeon focal experience has a greater effect on surgeon performance. We also demonstrate that sub-task experience has different, non-linear performance relationships for focal and related experience. Finally, we find that focal experience is more firm-specific than related experience and that non-firm experience reduces the learning rate for both focal and related experience. We discuss implications of our findings for healthcare delivery and operations management.
