Abstract
INTRODUCTION: Nonadherence is an important and highly prevalent issue in bipolar disorder, which may have serious consequences. Surprisingly, few studies have been carried out in patients with clinical stability to explore risk factors for nonadherence.
METHOD: Adherence was assessed in 76 bipolar disorder patients with clinical stability using objective and subjective methods, both with a cross-sectional approach and a 3-year retrospective period. Possible associations between nonadherence and sociodemographic, clinical, treatment-related, psychopathological, psychological-subjective and result variables were also assessed.
RESULTS: 36.8% of patients were nonadherent. These patients showed greater concerns about medicines, worse functionality, a greater number of episodes and depressive episodes, higher prevalence of psychiatric comorbidities, present and/or past substance use or abuse and a history of depressive episodes with psychotic symptoms. A multivariate analysis revealed that concern about medicines, present and/or past substance use or abuse and psychiatric comorbidities were independently associated with nonadherence.
CONCLUSIONS: Nonadherence is a frequent phenomenon in bipolar disorder, even in patients with clinical stability. Clinicians should assess patients’ beliefs and attitudes towards medicines and help them reevaluate those issues with a more realistic perspective. Clinicians should also take actions to prevent substance use or abuse. Identification of nonadherence risk profile in bipolar disorder patients in clinical stability, adds complementary information to the identified risk profile in acute phases of the disease.
