AB Background Primary care teams record cardiovascular risk factor data on their patients to help them identify and treat patients eligible for prevention. However, it is not known to what extent this information is already available to clinicians, or the extent to which it is used.Aim To assess the extent to which risk factor is recorded, and to determine the cost-effectiveness of using recorded risk factor information in order to identify and treat eligible patients.Design of study An Excel-based model of the incremental costs and benefits of assessment and treatment.Setting Two general practices in the West Midlands.Method Untreated, non-diabetic patients, aged 35–74 years, were identified from each practice, and risk factor data was uploaded into an Excel spreadsheet. The completeness of risk factor data was assessed. The costs and benefits of assessing and treating patients, in descending order of estimated cardiovascular risk, were then modelled.Results In each practice, 72.9% and 77.7% of patients had a record of their blood pressure, 26.9% and 25.7% were eligible for at least one treatment: aspirin was the most common treatment followed by antihypertensives. With patients systematically assessed in descending order of cardiovascular risk, 78% of eligible patients and 87% of preventable cardiovascular events are found in the first two deciles of the target population.Conclusions Lack of risk factor information is not the principal constraint on cardiovascular prevention. Practices have sufficient risk factor data to inform an efficient, targeted prevention strategy.
