Access to Care: Health Care Utilization 2008 National Healthcare Quality and Disparities ReportsThe 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.
