Clinical microsystems, part 2. Learning from micro practices about providing patients the care they want and need

Usual medical care in the United States is frequently not a satisfying experience for either patients or primary care physicians. Whether primary care can be saved and its quality improved is a subject of national concern. An increasing number of physicians are using microsystem principles to radically redesign their practices. Small, independent practices-micro practices-are often able to incorporate into a few people the frontline attributes of successful microsystems such as clear leadership, patient focus, process improvement, performance patterns, and information technology.

An exemplary microsystem will (1) have as its primary purpose a focus on the patient-a commitment to meet all patient needs; (2) make fundamental to its work the study, measurement, and improvement ofcare-a commitment to process improvement; and (3) routinely measure its patterns of performance, "feed back" the data, and make changes based on the data.

The literature and experience with micro practices suggest that they (1) constitute an important group in which to demonstrate the value of microsystem thinking; (2) can become very effective clinical microsystems; (3) can reduce their overhead costs to half that of larger freestanding practices, enabling them to spend more time working with their patients; (4) can develop new tools and approaches without going through layers of clearance; and (5) need not reinvent the wheel.

Patient-reported data demonstrate how micro practices are using patient focus, process improvement, performance patterns, and information technology to improve performance. Pati ents should be able to report that they receive "exactly the care they want and need exactly when and how they want and need it."
