This case study focuses on Norman Regional Health System's achievement in providing recommended treatment on process-of-care, or "core," measures. Nearly a decade ago, Norman’s Board chair and a top physician administrator became champions for quality improvement, motivated by the fact that Norman had achieved just average scores on quality measures. Organizational, cultural, and system changes at Norman Regional, including the development of order sets and care plans, performance data transparency, concurrent review for certain patient groups, as well as a pharmacist-driven intervention, have led to sustained progress. For further information about the public hospital selection process and cross-cutting lessons about their improvement efforts, please see our introduction to the public hospital case study series.
