Laboratory reporting of framingham risk score increases statin prescriptions in at-risk patients

The under-utilization of cardiovascular preventative therapy with statins warrants novel interventions to optimize prescriptions in at-risk patients. We investigated the role of a laboratory generated Framingham Risk Score (FRS) provided to primary care clinicians in changing statin use in a primary care setting.

Data was acquired from the electronic medical records of 1573 anonymized patients undergoing routine lipid testing. Follow-up statin use and low-density lipoprotein cholesterol levels were obtained for 2 years post intervention. FRS parameters were entered into a laboratory information system, and provided to ordering physicians along with the cholesterol profile and the appropriate current Canadian Dyslipidemia treatment recommendation in a single report. Statin prescription rates following the intervention were compared with historical use 6 months prior to the study.

A total of 1283 participants (mean age of 60 ± 11 years) had an FRS report and were considered for analysis. Two hundred individuals filled a statin prescription in the 6 months prior to their index lipid test, and an additional 84 filled a statin prescription following the intervention (42% increase). The relative and absolute increase in statin prescription was 47.3% and 13.6% in the high-risk group p < 0.001, 53.3% and 8.1% in the intermediate-risk group p < 0.001, and 17.0% and 1.42% in the low-risk group p = 0.008, respectively.

The use of the laboratory reported FRS was associated with a significant increase in the rate of statin prescription across all risk groups. The expansion of FRS reporting across other health regions would improve cardiovascular risk prevention.
