From the Agency for Healthcare Research and Quality (AHRQ):
The National Healthcare Quality Report (NHQR) is a comprehensive national overview of quality of health care in the United States. It is organized around four dimensions of quality of care: effectiveness, patient safety, timeliness, and patient centeredness. The National Healthcare Disparities Report (NHDR) examines disparities in health care among priority populations, such as women and racial and ethnic minority groups. The reports are compiled from multiple Federal, State, and private data sources, including databases and surveys.
