Introduction Standard of care after an acute myocardial infarction (AMI) includes high‐intensity statin therapy to lower the risk of future cardiovascular events. However, the use of high‐intensity statins post‐AMI remains suboptimal, presenting an opportunity for clinical pharmacist services to improve clinical care. Objective To evaluate the impact of a cardiology clinical pharmacist intervention upon the rate of high‐intensity statins issued at hospital discharge after AMI. Methods This was a single‐center, pre‐post study that included patients 18 to 75 years of age who were discharged from one investigative site with a primary diagnosis of AMI (as determined by ICD‐10 codes) between July 2019 to December 2020. The primary outcome was the proportion of patients prescribed high‐intensity statins, defined as atorvastatin 40 to 80 mg or rosuvastatin 20 to 40 mg daily, at discharge pre and postimplementation of a cardiology clinical pharmacist intervention. Patients were stratified into two groups for comparison: pre‐ (07/01/2019‐3/31/2020) and post‐ (04/01/2020‐12/31/2020) intervention, for which the latter included cardiology pharmacist‐driven communication and documentation via the electronic health record. Results A total of 418 patients were included: 223 (53.3%) preintervention and 195 (46.7%) postintervention. The overall cohort was approximately two‐thirds men and 90% Caucasian, with a mean ± SD age of 61.4 ± 9.7 years; the pre and postintervention groups were similar in terms of demographics. The rate of high‐intensity statin prescribing at discharge improved from 83.0% preintervention to 95.4% postintervention (P <.0001). A total of 9.9%, 1.8%, and 5.4% of patients in the preintervention group received moderate‐intensity, low‐intensity, or no statin at discharge, respectively, lowering to 3.1%, 1.0%, and 0.5% postintervention. Conclusion There was a statistically significant increase in the rate of high‐intensity statin prescribing post‐AMI after the implementation of targeted cardiology clinical pharmacist services.
