The 1990s is truly the era of increased accountability in the practice of medicine. Through the methods of cost and quality measurement and the introduction of a manager (i.e., the MCO), society as a whole will benefit from a medical delivery system that focuses on linking the outcomes of care delivered to the processes of the care provided. Report cards serve an important tool by which information about quality and costs can be quantified and shared with the purchasers and users of the medical delivery system. Purchasers and patients are asking for greater accountability from payers and providers. The increased accountability of physicians to health plans, IDSs, hospitals, and patients with whom they interact has major implications on the definition of success in the managed medical delivery system of today. The theme of accountability has been described by the examples of the HEDIS Quality Report Card for health plans and Quality Report Cards for hospitals, PCPs, and specialists. Physicians must provide high-quality care to each patient they see but must also develop the mindset and structures to manage an entire population of patients. The expectations of each of the entities with whom they interact must be understood, and physicians need to develop the skills and infrastructure to put total quality management and information technology to work to help them facilitate the delivery of high-quality care in a cost-effective manner. Everyone involved in the health care system--from purchasers to payers to consumers--shares the same goals as physicians: provide the highest-quality care and achieve the best possible outcomes in the most cost-effective manner.
