The validity of the diagnosis of acute myocardial infarction in routine statistics: a comparison of mortality and hospital discharge data with the Danish MONICA registry

Madsen, M·2003·Journal of Clinical Epidemiology

Abstract

We analyzed the validity of the diagnosis of acute myocardial infarction (MI) in national registries by individual record linkage with the Danish MONICA registry. MI events were identified by record linkage between The National Hospital Registry and The National Death Registry. The sensitivity and specificity were estimated based on three different definitions of an MI event. For events with MI as the primary diagnosis or underlying cause of death the predictive value was 93.6% and sensitivity 77.6% when compared to DANMONICA definite or possible MI. Compared to DANMONICA, definite MI the predictive value was 75.0% and the sensitivity 92.8%. When secondary diagnosis and contributory cause of death were included, the sensitivity increased and the predictive value decreased only slightly. The combination of the national registries was found to be a valid and powerful tool for monitoring the population incidence of MI.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
