我们通过与丹麦MONICA登记处的个体记录联系，分析了国家登记处中急性心肌梗死（MI）诊断的有效性。MI事件通过国家医院登记处和国家死亡登记处之间的记录联系确定。根据MI事件的三种不同定义估计灵敏度和特异性。与DANMONICA明确或可能的MI相比，MI作为主要诊断或潜在死亡原因的事件的预测值为93.6%，灵敏度为77.6%。与DANMONICA比较，明确MI的预测值为75.0%，敏感性为92.8%.当包括次要诊断和死亡原因时，敏感性增加，预测值仅略有下降。国家登记系统的组合被认为是监测MI人群发病率的有效和强大的工具。(C)2003年爱思唯尔科学公司All rights reserved.
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. (C) 2003 Elsevier Science Inc. All rights reserved.
