How valid is register data for identifying acute myocardial infarction and acute stroke compared to hospital records?
Register data for acute myocardial infarction and acute stroke has high positive predictive value (94-96%), but suspected or unspecified diagnoses also contain a significant proportion of definite events, necessitating validation with hospital records.
Lindblad et al. (1993) conducted a cohort in Acute myocardial infarction and acute stroke. Register data vs. Hospital records was evaluated on Confirmation of first event of acute myocardial infarction and acute stroke.
