^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 event had occurred. For emergency visits, adverse effects were identified by International Classification of Diseases, Ninth Revision (ICD-9) codes of 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 A proportion of race data were missing in each year. Race data were missing from 30.2% of the 2007–2008 and 14.3 % of 2008–2009 adverse effect 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.

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

Key: MSA: metropolitan statistical area; SE: standard error.
