In its 2001 report Crossing the Quality Chasm, the Institute of Medicine outlined six domains of quality in medical care: safety, effectiveness, patient-centeredness, timeliness, efficiency and equity. But, Dr. Tara Bishop writes in a new viewpoint article published online March 21, in the Journal of the American Medical Association (JAMA), current quality measures for the outpatient setting do not include all of these domains. As a result, quality measurement and quality improvement efforts in the outpatient setting have neglected critical areas of high quality care.
