2011 National Healthcare Quality and Disparities Reports

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.

^a. Rates were computed using 2000-based postcensal estimates of the civilian noninstitutionalized population as of July 1 of each data year. Adverse effects of medical care were identified as office-based physician and hospital outpatient department visits for which a checkbox indicated that an adverse medical/surgical or medicinal drug effect had occurred. For emergency visits, adverse effects were identified by International Classification of Diseases, 9th Revision codes 995.0, 995.2, 995.4, or 996-999, or by a verbatim reason for visit or cause of injury indicating adverse medical, surgical, or drug effects.

^b. Race was missing from 14.3% of the 2008-2009 visit data. Missing data were imputed, and standard errors were inflated consistent with the guidance in 2007 NAMCS Microdata File Documentation, ftp://ftp.cdc.gov/pub/Health_Statistics/NCHS/Dataset_Documentation/NAMCS/doc07.pdf. These data should be interpreted with caution.

DSU - Data do not meet the criteria for statistical reliability, data quality, or confidentiality.

Key: AI/AN: American Indian or Alaska Native; NHOPI: Native Hawaiian or Other Pacific Islander; MSA: metropolitan statistical area; SE: standard error.
