Adesão medicamentosa de pacientes hipertensos usuários do sistema único de saúde e da rede suplementar

Abstract

Background: The lack of adherence to medication is a significant risk factor contributing to the inadequate treatment of systemic arterial hypertension and its consequent negative repercussions. Objective: To evaluate the current situation of the degree of drug adherence of hypertensive patients and to relate them with the influencing factors in this process. Methods: An observational, cross-sectional study was performed with hypertensive patients over 18 years of age, attended at a single health hospital and two hospitals in the supplementary network, in Aracaju (SE), through interviews conducted during the 2017 to December 2018. Adherence was determined by a validated therapeutic adherence scale. Patients with a score equal to 8 on the scale were considered adherent. Results: The frequency of therapeutic adherence among the 331 patients interviewed was 19.9%, with 80.1% considered non-adherent. Among the latter, 54.1% presented low therapeutic adherence, and 26%, mean adherence. Among the variables investigated in this study, only sex (p = 0.017), diagnosis time (p = 0.016), and non-scheduled visit in the last 12 months (p = 0.002) were associated with adherence. Conclusion: There was an inadequate medication adherence in the patients investigated. Most were considered non-adherent. Of these, more than half had a low degree of adhesion
