Pharmaceutical Follow-up of Coronary Heart Disease (CHD) Patients

Objectives To explore the impact of a clinical pharmacist-led 12 month lasting follow-up program for patients with established coronary heart disease (CHD) discharged from the North Norway University Hospital. Methods A total of 102 patients aged 18-82 years were enrolled in a non-blinded, randomized controlled trial. The intervention comprised medication reconciliation, medication review and patient education during three meetings; at discharge, after three months and after twelve months. The control group received standard care from their general practitioner. Primary outcomes were adherence to clinical guideline recommendations concerning prescription, therapy goal achievement and lifestyle education defined in the medication assessment tool for secondary prevention of CHD (MAT-CHDSP). Secondary outcomes included changes in the biomedical risk factors cholesterol, blood pressure and blood glucose. Key findings Ninety-four patients completed the trial, 48 intervention group patients and 46 controls.

Appropriate prescribing was high, but therapy goal achievement was low in both study groups throughout the study. Overall adherence to MAT-CHDSP criteria increased in both groups and was significantly higher in the intervention group at study end compared to the control group, 78.1% vs. 61.4%, P < 0.001. The difference was mainly due to an increased documentation of lifestyle advices in intervention group patients.

No significant improvements in biomedical risk factors were observed in favor of the intervention group, possible due to an underpowered study. Conclusion The clinical pharmacist-led follow-up program significantly increased documented lifestyle advices defined in the MAT-CHDSP for the intervention group, but did not lead to significant improvements in biomedical risk factor measures in favor of the intervention group. Even if prescribing was high, therapy goal achievement was low in both study groups. Changes to the follow-up program are warranted, in addition to a larger, adequately powered study, before implementation in standard patient care can be recommended.
