Quality improvement: an imperative for medical care.

For continuous process improvement to be successful at the site of care, an organizational structure for quality improvement should be in place. Quality improvement requires (1) an environment for quality improvement and (2) tools for improvement, including statistical and meeting tools. Physicians and all other care givers and support personnel must cooperate for process knowledge to be complete and usable. Perhaps there is no such thing as a purely "clinical" system, because the contiguous systems influence clinical behavior so completely they are almost inseparable. Process improvement specifications are not the same thing as standards as we now understand them. Process improvement specification are process based. They expect, are designed for, and handle divergent pathophysiologic conditions by focusing on processes. Individual institutions define and measure their outputs, but these outputs are judged against their customers' needs and expectations (thereby becoming outcomes) for performance, features, reliability, conformance, durability, serviceability, aesthetics, and perceived quality. Outcomes research as known today can help us understand the needs and expectations of our customers. Moreover, any team can improve the framework of quality improvement.
