Evaluation of nonadherence to treatment among patients with schizophrenia attending psychosocial care centers in the south region of Brazil.

ABSTRACT

INTRODUCTION: The treatment of schizophrenia aims to reduce symptoms, improve quality of life and promote recovery from debilitating effects. Nonadherence to treatment is related to several factors and may lead to persistence of symptoms and relapse. Worldwide, the rate of nonadherence to treatment in individuals with schizophrenia is around 50%. OBJECTIVES: To compare the clinical profile of nonadherent and adherent patients among individuals diagnosed with schizophrenia receiving treatment at psychosocial care centers in a city in southern Brazil. METHOD: The clinical-epidemiological profile of patients with schizophrenia was retrospectively analyzed based on medical records entered into the system between January and December 2016, evaluating data at one-year follow-up. RESULTS: 112 patients were included. The disease was more prevalent in men; mean age was 40.5 years, being lower among men. Most of the sample had a low level of education, was unemployed/retired, did not have children and resided with relatives. The highest rate of diagnosis was among young adults. Psychotic symptoms were most frequently described, and the most commonly prescribed antipsychotic was haloperidol. The nonadherence rate was 15.2%; only one patient required admission to a psychiatric hospital. Among nonadherent patients, the mean time of attendance was 6 months; there were more nonadherent women than men. The most prevalent age range of nonadherence was 41-64 years. Psychosocial and clinical data were similar across the whole sample. CONCLUSION: A nonadherence rate of 15.2% was found among individuals receiving treatment for schizophrenia, suggesting that psychosocial care centers were effective in treating and monitoring these patients.
