IJCM_195A: Prevalence of Drug Adherence Among Hypertensive Patients attending Primary Health Centre - A Cross sectional Study

Abstract

Background: There is an increase in prevalence of hypertension 31.5% in urban and 26.2% in rural dwellers of Tamil Nadu (ICMR-INDIAB study). Adherence to hypertension medication is very important for improving the quality of life and preventing complications. In this study we aim to estimate the drug adherence among hypertensive patients using Morisky Medication Adherence Scale. Objectives: To estimate the prevalence of drug adherence and its influencing factors among hypertensive patients in Rural Health Training Centre areas of Madras Medical College. Methodology: 180 Hypertensive patients attending Non-Communicable Disease clinic from two rural health centres 90 patients from each Padiyanallur PHC and Medavakkam PHC were recruited for the study. In this study we have used The Morisky Scale MMAS-4 to address medication adherence. Results: Study results showed that 32.62% of hypertensive patients had high adherence to antihypertensive medications,53.48% patients had medium adherence whereas 13.9% patients had low adherence. Adherence to drug is higher among females (36.9%) than males (29.1%). Patients with low to medium adherence to antihypertensive drugs are having more than 10% risk of developing cardiovascular disease (OR – 3.6, 95% CI – 1.86 to 6.75) than their counterpart. Patients with good knowledge (42%) had high adherence than people with poor knowledge (24.2%) Conclusion: The study reported only 32.62% were found to be adherent to antihypertensive medications. To ensure high level of control among hypertensive sustained and focussed interventions should be implemented at all levels of health care.
