Medication adherence in first-episode psychosis patients in Singapore.

Abstract:

AIM:Early intervention programmes for first episode psychosis (FEP) aim to reduce the duration of untreated psychosis (DUP) and improve functional outcomes. The sustained maintenance of improved outcomes depends largely on patients' adherence to prescribed treatment. This paper examines the prevalence of non-adherence in a cohort of patients with FEP and the sociodemographic and clinical factors associated with non-adherent behaviour. METHODS:The sample included consecutive patients accepted from 2007 to 2012 into the Early Psychosis Intervention Programme (EPIP) in Singapore. Sociodemographic variables as well as DUP, insight, severity of psychopathology and clinical diagnoses were collected. Patients were assessed at baseline and 1 year with the PANSS and Global Assessment of Functioning Scale (GAF). Medication adherence was grouped into 3 categories: no-adherence, partial adherence and regular adherence. RESULTS:Of the 445 patients included, 51% were male with a mean age of 26.3 years, 74.6% had schizophrenia spectrum and delusional disorders, 14% had affective psychosis and 11.3% had brief psychotic disorder or psychotic disorder not otherwise specified. At 1 year follow up, 65.5% reported regular adherence, 18.7% were partially adherent and 15.8% were non-adherent. Non-adherence was correlated with male gender, living alone and having poorer judgement and insight. Partial adherence was associated with Malay ethnicity and having undergone national service. CONCLUSION:Medication adherence is prevalent in FEP and associated with a variety of factors. This study supports the use of culturally appropriate interventions in addressing barriers to adherence. Further studies would need to be done to address specific factors affecting adherence outcomes.
