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, 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.
