PURPOSE: American College of Cardiology/American Heart Association guidelines recommend high-intensity statin therapy and consideration for nonstatin therapy for patients with peripheral vascular disease (PVD); however, utilization rates remain suboptimal. The primary objective of this study was to determine whether pharmacist intervention for patients with PVD could improve the percentage of patients discharged on a high-intensity statin.

METHODS: The study used a single-center pre/post design and included patients with PVD who underwent peripheral bypass during their admission. Postintervention patients managed with an order set including a preselected consult for a pharmacy lipid protocol were compared to preintervention patients managed using the order set without the consult. The primary outcome was the percentage of patients discharged on a high-intensity statin. Secondary outcomes included intensification of statin therapy, the addition of ezetimibe, and referral to an outpatient lipid clinic.

RESULTS: A total of 175 patients were included in the analysis, with 94 patients in the preintervention group and 81 patients in the postintervention group. The primary outcome met statistical significance, with an increase in the percentage of patients discharged on a high-intensity statin in the postintervention group (70.4%) compared to the preintervention group (38.3%) (P < 0.001; 95% confidence interval, 1.37-2.46). Secondary outcomes that met statistical significance included an increase in the percentage of patients with any increase in statin intensity (35.8% vs 20.2%; P = 0.02).

CONCLUSION: The addition of a pharmacist consult led to an increase in the percentage of patients discharged on a high-intensity statin and an increase in overall statin intensification.
