A steady flow of efficiency and effectiveness-focused Managed Care articles in recent months have prompted the launch of this special edition. Managed Care services are one-stop healthcare provider networks, such as Health Maintenance and Preferred Provider Organizations (HMO and PPO). Financial control and service quality as well as practice regulation and shared risk taking are important considerations in these organizations. This poses the question that even if Managed Care regulators keep service quality on the front burner and finances aren’t allowed to dominate then is there a risk that QA gets lost in the Managed Care milieu? In this e-book the authors have pushed back the frontiers to generate original insights in to the efficiency and effectiveness of Managed Care organizations.
