Determinants of adherence to antihypertensive treatment among patients attending a primary care clinic with limited medical armamentarium in Delhi, India: A qualitative study.

OBJECTIVE

To determine perspectives on reasons for non-adherence to antihypertensive therapy and its socioeconomic determinants among patients attending a primary care center in a low-income area in Delhi, India.

METHODS

We conducted in-depth interviews with a total of 30 patients having hypertension at a primary care facility located in a low-income urban area in Delhi.

RESULTS

All the participants were aware that hypertension was a serious illness, and medication intake was necessary throughout life to prevent uncontrolled hypertension. All participants in varying quantities practiced salt restriction, but the consumption of fresh fruit and vegetables was low primarily due to economic reasons. The participants were unable to differentiate the concept of exercise from physical activity. Medication adherence was suboptimal, and significant reasons for non-adherence were forgetfulness, carelessness and running out of drug stocks. Blood pressure control was also suboptimal in a majority of the participants, but combination therapy was restricted due to limited medical armamentarium at the clinic. Laboratory investigations for monitoring target end-organ damage were either delayed or not conducted in most participants.

DISCUSSION

Hypertensive patients undergoing treatment at primary care facilities often report suboptimal medical adherence and treatment outcomes, with socioeconomic causes being a major driver of non-adherence.
