Race differences in estimates of sudden coronary heart disease mortality, 1980-1988: The impact of ill-defined death

Race differences in estimates of sudden coronary heart disease mortality, 1980-1988: The impact of ill-defined death

Journal of Clinical Epidemiology 49(11): 1247-1251

Coronary heart disease (CHD) deaths occurring outside of hospitals or in emergency rooms (OH/ER) have been used to estimate sudden CHD mortality. This study quantifies the potential impact of natural deaths coded to an unspecified cause on race differences in sudden CHD estimates, during 1980-1988. Death certificate data for OH/ER deaths in 40 U.S. states were used to create annual age-adjusted rates for sudden CHD and sudden CHD rates revised to include deaths with an unspecified cause (ICD9, 780-799). Revising the mortality rates to include unspecified deaths results in greater racial disparities for estimates of sudden CHD. In 1980, black-white race differences went from 89 to 128 and 103 to 121 (per 100,000) for men and women, respectively, with revision. Among blacks, revised sudden CHD mortality declined approximately 22%, during 1980-1988, compared to 10% for unrevised sudden CHD; with no observed effect of revision on percent declines among whites. Previous studies may have underestimated declines in racial disparities of sudden CHD, due to improved quality of OH/ER death certification among blacks. Improved access to routine and emergency medical care, through increased affordability and greater availability, may be important to address higher OH/ER CHD among blacks.
