Validity of register data on acute myocardial infarction and acute stroke : The Skaraborg Hypertension Project
Sammanfattning
In the evaluation of a hypertension treatment program, the end-point surveillance included incidence of acute myocardial infarction and acute stroke identified from hospital in-patient registers and the national mortality register. To ascertain the validity, in-patient records containing the ICD-codes 410-411 and 430-438 were validated.
