Clinical and Economic Impact of Clinical Pharmacy Service on Hyperlipidemic Management in Hong Kong

Objective: To assess the clinical and economic outcomes of a clinical pharmacy service (CPS) in dyslipidemic management. Method: This was a 24-month prospective controlled trial conducted at the lipid clinic of a public hospital in Hong Kong. In the intervention group, a clinical pharmacist assessed low-density lipoprotein cholesterol (LDL-C) levels and provided recommendations in accordance to the Adult Treatment Panel III (ATP III) guidelines. Medication compliance and the proper use of drugs were assessed. Education on healthy lifestyles was reinforced. Monthly telephone follow-ups were made to check on the progress of patients. In the control group, patients received usual medical care with no pharmacist intervention. Primary outcome was the percentage of patients achieving the ATP III LDL-C goal at the end of study. The estimated cost of such service was also evaluated. Results: A total of 300 patients were recruited into the study (150 in intervention group and 150 in control group). In the intervention group, 58.7% patients achieved LDL-C goals compared with 45.3% in the control group (P < .05). The intervention group achieved 26.4%, 17.4%, and 30.0% mean reduction in LDL-C, total cholesterol (TC), and triglycerides (TG) levels, respectively, compared with 12.6%, 6.6%, and 11.5% in the control group (P < .05). The estimated cost for this clinical service was US$385/month for a total of 600 dyslipidemic patients seen per year. Conclusion: The results of this study demonstrate the positive impact CPS can have on achieving treatment goals in lipid management. Similar services for other problematic conditions such as hypertension and diabetes mellitus may also be benefited by similar CPSs.
