A multicenter study of the coding accuracy of hospital discharge administrative data for patients admitted to cardiac care units in Ontario.

摘要: Abstract Background Cardiac health services researchers frequently use cohorts derived from administrative hospital discharge abstract data to study the outcomes and treatment of coronary artery disease. However, relatively limited exist on accuracy coding cardiac diagnoses in data. The goal this was examine acute myocardial infarction other Canadian Institute Health Information abstracts. Methods Patients admitted 58 care units (CCUs) Ontario that participated Fastrak II Acute Coronary Syndromes registry were linked CIHI most responsible diagnosis at compared with CCU clinical registry. Results A total 58,816 patients specificity, sensitivity, positive predictive value a 92.8%, 88.8%, 88.5%, respectively. specificity codes for arrhythmia, congestive heart failure, unstable angina, chest pain not yet diagnosed all least 93.9%. sensitivity these no greater than 60.7%. Furthermore, values larger 80.8%. Conclusion Myocardial is generally accurately coded are less reliably (Am Heart J 2002;144:290-6.)
