Dimensions of Access to Antihypertensive Medications in Ceilândia, Distrito Federal, Brazil

Abstract

Access can be understood as the sum of a number of elements of the interface between patients and the health care system. This study took a comprehensive approach to the dimensions of access to medications, employing indicators to evaluate the dimensions of access to antihypertensive medications in Ceilândia, DF, Brazil. This was a cross-sectional epidemiological study, administering questionnaires during home visits. The survey covered epidemiological and socioeconomic profiles, behavioral habits and the dimensions of access to antihypertensive medications comprising physical, financial, and geographic availability and accept ability according to the hypertensive population of Ceilândia. The total sample comprised 400 individuals and the hypertensive subset numbered 140 (35%). Indicators of physical availability of medications revealed that users found it difficult to acquire their drugs on almost one third of occasions and in some cases were unable to access any of these products. The greatest barriers to access were reported by users of pharmacies belonging to the Brazilian National Health Service (SUS) and on the "People's Pharmacies" network. More than one third of the hypertensive sample spent their own money on medications they could not find at these pharmacies. The majority of the hypertensive subsets were overweight/obese, a minority engaged in physical activity and 40% were smokers/ex-smokers. More women reduced their salt intake. Men had higher incomes, educational level, and socioeconomic status. Failure to keep the public health care system supplied has prejudiced access to essential medications for hypertension treatment, transferring the costs onto users. This population has lifestyle habits that increase the risk of exacerbation of hypertension. These results reveal a F. X. C. Salgado et al. 1518 need for effective public policies to ensure access to antihypertensive medications and involve users of the health care system in changing their habits and behaviors in order to achieve adequate and lasting control of systemic arterial hypertension.
