The diabetes audit and research in Tayside Scotland (DARTS) study : electronic record linkage to create a diabetes register.
To identify all patients with diabetes in a community using electronic record linkage of multiple data sources and to compare this method of case ascertainment with registers of diabetic patients derived from primary care.
Electronic capture-recapture linkage of records included data on all patients attending hospital diabetes clinics, all encashed prescriptions for diabetes related drugs and monitoring equipment, all patients discharged from hospital, patients attending a mobile unit for eye screening, and results for glycated haemoglobin and plasma glucose concentrations from the regional biochemistry database.
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.
Main outcome measures
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. (...)
