Writing in 1988, Arnold Relman heralded the dawning of the “third revolution“ in medical care. The first revolution, at the end of World War II, had inaugurated an Era of Expansion, with an explosion of hospitals, physicians, and research. Medicare and Medicaid were passed, and medicine experienced a golden age of growth. Inevitably, according to Relman, this yielded to an Era of Cost Containment starting in the 1970s. The federal government and private employers revolted against soaring costs, brandishing the weapons of prospective payment, managed care, and global budgeting. Yet these blunt instruments of cost-cutting eventually produced concern over how to evaluate the quality of health care, to promote the good while trimming the bad. Thus Relman announced the arrival of the Era of Assessment and Accountability.
This chronology helps explain the current importance of quality. Quality assessment and more recently, quality improvement techniques, occupy a central place in this new era.
