Complementary and alternative medicine use among hypertensive patients receiving biomedical treatment: a cross-sectional survey at the LEKMA General Hospital in Accra, Ghana

Background: Complementary and alternative medicine (CAM) use is on the increase globally and there is an increased rate of usage among hypertensive patients. Objective: This study was designed to describe CAM use among hypertensive patients at a municipal hospital. Methods: A cross-sectional survey of hypertensive patients at a Municipal Assembly Hospital was conducted. Respondents were made up of 209 (99 CAM users and 110 non-Cam users) selected randomly from patients attending the hypertension clinic. The pattern of CAM use, clinical profiles of respondents, and their attitudes toward CAM were examined. Descriptive statistics and the Chi Square test were used for data analysis. Results: Out of the 209 patients interviewed, 99 (47.36%) had used at least one type of CAM mostly herbal products (72.72%, n = 72). The CAM users demonstrated poorer adherence to antihypertensive medications (30.30%, n =30) as compared to non-CAM users (8.08%, n = 80). We observed a positive association between non-CAM use and medication adherence (p = 0.001). The majority (72.72%, n = 72) of the CAM users claimed to have obtained the expected effect, however, 89.89% (n = 89) did not disclose their CAM use to their physician. They cited lack of inquiry by physicians as the main reason for non-disclosure. Conclusion: A considerable proportion of hypertensive patients receiving conventional treatment at a municipal hospital also use CAM therapies. Physicians should be encouraged to inquire about the history of CAM use among their patients to be able to advise patients concerning the possible adverse reactions and drug interactions.
