The validity of the Finnish Hospital Discharge Register and Causes of Death Register data on coronary heart disease.
2005
Background and design The recent introduction of sensitive markers of myocardial injury is likely to affect the epidemiology of coronary heart disease (CHD). The American Heart Association together with other societies and research agencies have recently published a new definition on acute CHD to improve consistency in epidemiological and clinical studies (referred here as the ‘2003 definition').Methods In this study we compare the data on CHD events in the Finnish National Hospital Discharge Register (HDR) and the Causes of Death Register (CDR) with the population-based myocardial infarction (MI) register, FINMONICA/FINAMI. The FINMONICA/FINAMI events were classified according to the 2003 definition. The relevant International Classification of Diseases (ICD) codes from the HDR and CDR were used.Results Using the 2003 definition as the reference, the overall sensitivity of the ICD codes for MI in the combined HDR and CDR was 83% and the positive predictive value (PPV) was 90%. When the ICD codes for unst...
