Satisfaction With Statin Treatment Among Adult Coronary Artery Disease Patients: An Experience From a Resource-Constrained Setting.

BACKGROUND

Statins are the most widely prescribed hypolipidaemic drugs for coronary artery disease (CAD) patients, but have been found to cause muscle and nerve related adverse effects which can affect patient satisfaction with treatment. Literature on treatment satisfaction among statin users, especially from resource-limited settings is inadequate. The aim of this cross-sectional study was to assess the level of satisfaction with treatment among statin users and evaluate the relationship between adverse effects experienced by patients and their satisfaction with the medication.

METHODS

This study included 300 adult CAD patients visiting the cardiology department of a tertiary care hospital in the northern region of India, who were prescribed statins for their diagnoses. An interviewer administered, validated and standardised Treatment Satisfaction Questionnaire for Medication (version 1.4) was used for data collection.

RESULTS

Around three quarters of the population reported being overall satisfied with their medication. Mean scores were calculated for Effectiveness, Convenience, Side-Effects and Global Satisfaction. The patients reported high scores (above 60%) for all domains. Those experiencing any adverse effect were found to be more likely to report lower effectiveness. Additionally, medication effectiveness showed a positive correlation with overall treatment satisfaction.

CONCLUSIONS

The study shows that treatment satisfaction is critical to gauge patient experiences with the treatment which can impact medication adherence and compliance. It's a crucial measure especially among CAD and other chronic disease patients since greater satisfaction can improve clinical outcomes. More research is warranted to better understand the relationship between medication effectiveness and treatment satisfaction.
