In recent years, the Joint Commission on Accreditation of Healthcare O
rganizations (JCAHO) has expanded its traditional role as a leading ev
aluator of health care organizations to incorporate new attitudes and
strategies in the areas of quality and performance improvement. This p
aper outlines plans for modifying the current accreditation process, a
nd includes a proposition that accredited organizations actively parti
cipate in a quality measurement system and become involved in the proc
ess of selecting appropriate measures. The paper presents current and
proposed methods for measuring performance standards, compares major a
ccreditation systems, and explores the public's expectations for healt
h care quality and the JCAHO's role in quality improvement and cost co
ntainment.
