Controlled trial of effect of documented cardiovascular risk scores on prescribing

Abstract
We recruited patients with type 2 diabetes who had no history of cardiovascular disease or renal disease. All patients were aged 35–75 years and attending a hospital outpatient clinic. We recruited 323 patients (167 men and 156 women) attending the clinic consecutively. Patients were seen by one of six doctors who were unaware of the ongoing project. We allocated patients alternately to the experimental and control groups (162 experimental, 161 control), and all doctors saw an equal number of experimental and control patients. The University of Dundee special study module subcommittee approved this project on behalf of Tayside Committee on Medical Research Ethics.
