Perceptions and Practices towards Medication Non-Adherence among Hypertensive Patients: An Observational Study

Background The present study broadly evaluates the adherence to pharmacotherapy, perceptions, and practices among ambulatory hypertensive patients attending a cardiac institution in Karachi, Pakistan. Methods A cross-sectional, single-center study was conducted at the National Institute of Cardiovascular Diseases Karachi, Pakistan. The study continued from 4 July 2019 to 3 September 2019. A total of 200 patients with a primary diagnosis of hypertension (HTN) were recruited for the study. The data was collected through a questionnaire based on a nine-item modified adherence predictor scale to assess medication adherence. Along with the demographic details patients smoking status, history of comorbidities and past complications were noted. Results It was found that the mean age of the study population was 56.45±12.36 years. A total of 62.5% of patients were taking medication daily while 15.5% were consuming medications intermittently and only 6.5% patients were not adherent at all. Around 35% patients preferred follow-up visits once in a month. Besides this, 35.5% patients never monitored their blood pressure while more than half of the studied population believed that their BP has mostly been controlled and skipped the prescribed medication. Conclusion The study indicated that the perception and awareness among the hypertensive patients regarding their medical condition are suboptimal. Concerted strategies like health education program and campaigns must be launched in order to help the sufferers.
