Diabetes registers from primary care were from a random sample of eight Tayside general practices.
A detailed manual study of relevant records for the 35 144 patients registered with these eight general practices allowed for validation of the case ascertainment.
Tayside region of Scotland, population 391 274 on 1 January 1996.
Prevalence of diabetes ; population of patients identified by different data sources ; sensitivity and positive predictive value of ascertainment methods.
Electronic record linkage identified 7596 diabetic patients, giving a prevalence of known diabetes of 1.94% (0.21% insulin dependent diabetes, 1. (...)
