This study investigated the impact of the use of a computer programme to collect data on cardiovascular risk factors, which could also provide patient education. A retrospective analysis was carried out of data recorded over three years in a general practice in Barnsley, an area with the second highest prevalence of ischaemic heart disease in England. The study found that use of a simple computer-based system by the primary care team led to 55% of the population being assessed within three years. Consequent patient education and lifestyle changes led to a reduction of risk factors in those at high risk who were re-screened. A possible reduction on admissions to hospital for cardiovascular disease was also noted.
