Cost-Justification of a Clinical Pharmacist-Managed Anticoagulation Clinic

Abstract

A cost-benefit evaluation of a clinical pharmacist-managed anticoagulation clinic (AC) was performed. Outpatient and hospital records were examined for 26 patients in the treatment group with an AC clinic and 26 patients in the control group. Therapeutic prothrombin times were maintained within the treatment group to a significantly greater extent than within the control group (p<0.001). The AC was successful in preventing hospitalizations resulting from hemorrhage or thromboembolic admissions (p<0.05, p<0.005, respectively). Patients were hospitalized 3.22 days and .048 days per patient-treatment-year in the control and treatment groups, respectively. The net savings in reduced hospitalization costs per year in the treatment group was $211,776. The benefit:cost ratio (B:C) was 6.55, suggesting the program is socially valuable. This clinical pharmacist-managed AC was effective in maintaining therapeutic prothrombin times, and reducing the incidence of hospitalizations resulting from anticoagulation complications, and can be cost-justified based on a cost-benefit analysis.
