Guide to Inpatient Quality Indicators: Quality of Care in Hospitals. Volume, Mortality, and Utilization. (Revision 4, December 22, 2004)

摘要

In health care as in other arenas, that which cannot be measured is difficult to improve. Providers, consumers, policy makers, and others seeking to improve the quality of health care need accessible, reliable indicators of quality that they can use to flag potential problems or successes; follow trends over time; and identify disparities across regions, communities, and providers. The Agency for Healthcare Research and Quality (AHRQ) Quality Indicators (QIs) are one Agency response to this need for multidimensional, accessible quality indicators. They include a family of measures that providers, policy makers, and researchers can use with inpatient data to identify apparent variations in the quality of inpatient or outpatient care. AHRQ's Evidence-Based Practice Center (EPC) at the University of California San Francisco (UCSF) and Stanford University adapted, expanded, and refined these indicators based on the original Healthcare Cost and Utilization Project (HCUP) Quality Indicators developed in the early 1990s. The AHRQ QIs are organized into three modules: Prevention Quality Indicators, Inpatient Quality Indicators, and Patient Safety Indicators. This report focuses on health care provided within the inpatient hospital setting. The Inpatient Quality Indicators include three distinct types of measures. Volume measures examine the volume of inpatient procedures for which a link has been demonstrated between the number of procedures performed and outcomes such as mortality. In-hospital mortality measures examine outcomes following procedures and for common medical conditions. Utilization examines procedures for which questions have been raised about overuse, underuse, and misuse.
