Fatores associados a não adesão aos retrovirais através do registro de dispensação de farmácia em um centro de referência no Sul do Brasil

Abstract

Objective: Evaluate non adherence to antiretroviral therapy and its associated factors in patients living with HIV / AIDS (PLWHA) treated at a referral Center in Southern Brazil. Methods: The ecological study of retrospective survey was developed in the Specialized Care Service (SAE) in the city of Pelotas. Adherence was assessed using the antiretroviral dispensing record (ARV) for the dispenser unit of drugs (UDM). The sample consisted of patients who withdrew their ARV in the first fifteen days of June 2013 and were followed for one year. The associated factors were evaluated by retrospective data collection from medical records. The mean time between removals was calculated to categorize patients into proper adherence and non-adherence. Patients who had taken ARV higher than the average of 37 days between withdrawals and / or abandoned the withdrawal of ARV were considered non-adherent. Results: 473 patients were eligible for the study. The prevalence of non-adherence was 25.6 %.The variables significantly associated with non-adherence were age < 45 years (p = 0.001), detectable viral load (p < 0.001), absence of clinical comorbidity of ischemic heart disease (p < 0.001). They have tended to increase risk of nonadherence: not present dyslipidemia (p=0. 07) and be in current or initial use scheme with IP (95% IC 0,99 to 1,14). Conclusions: Younger and seemingly healthier patients have higher proportions of non-adherence. Strategies to promote better adherence in this population should be prioritized by PLWHA services.
