Abstract

Non-adherence to treatment for hypertension increases the risk of disease complications. The factors associated with non-adherence in a resource poor settings should be determined so as to lower the impact of the disease on the health systems which are already overburdened with infectious diseases. This study was therefore carried out among a sample of 804 hypertensive patients to determine factors that are associated with non-adherence to antihypertensive treatment. A cross sectional study was carried out from April to December 2009 in District McGann hospital, a tertiary care centre and teaching hospital in Shimoga, Karnataka. The participants were chosen from the out-patients of General Medicine department using systematic sampling. They were aged 35 years and above, had been taking antihypertensive treatment for at least one month and gave informed consent to participate. Non adherence to antihypertensive therapy in the study population was 28.9%. Factors that were independently associated with non-adherence were: female sex, not understanding the drug regimen well, affordability to only some or none of prescribed drugs and longer time since last since last visit to a health care facility. Hence it is suggested that there is need to improve it through strategies helping patients understand their drug regimens, always availing drugs in the hospital so that they do not have to buy them and giving shorter time between visits to the nearest health care facility.
