Prevalence and pattern of use of complementary and alternative medicine (CAM) in hypertensive patients of a tertiary care center in India

Abstract

Objective: To study the prevalence and pattern of use of complementary and alternative medicine (CAM) in patients with essential hypertension.

Method: 521 consecutive patients visiting the Hypertension Clinic at the Postgraduate Institute of Medical Education and Research, Chandigarh, India, over a 6-month period were interviewed. Information was gathered on the patients' demographics, type(s) of CAM used, sequence of seeking CAM and conventional medicine, sources of recommendation, reasons for opting for CAM and areas of satisfaction and dissatisfaction associated with the use of CAM. Patients were also asked if they had informed their doctor about CAM use.

Results: It was observed that 63.9% of patients overall used CAM. Ayurveda was the most commonly used CAM (56.7%), followed by herbal medicines (14.4%). The most commonly cited reason by patients for using CAM was fear of adverse drug reactions of conventional medicines (59.0%). However, more than half of the patients eventually became dissatisfied using CAM. Only 5.4% of CAM users had informed their medical doctors about the use of CAM.

Conclusion: A significant proportion of patients receiving conventional treatment for hypertension also use CAM therapies. A better understanding of the pattern of CAM use amongst these patients will help dispel prevalent misconceptions concerning CAM and, at the same time, assist conventional practitioners to critically evaluate possible gaps or omissions in their own prescribing habits.
