RESUMO
AIM: Existing clinical guidelines have not yet identified an optimal duration of maintenance antipsychotic drug treatment for stable, remitted first-episode psychosis patients. This study compares the perception of relapse risk and attitudes towards maintenance medication among professionals in nursing and social work fields who have direct clinical experience with first-episode psychosis patients. We explore a perception model that identifies the decision-making factors in the clinical dilemma between relapse and maintenance. METHODS: A specially designed survey addressing perceptions of relapse risk and optimal duration of maintenance treatment was conducted among 63 experienced health-care professionals (30 nurses and 33 social workers) in the field of early psychosis in Hong Kong. RESULTS: Two clinically relevant themes were identified that affected professionals' judgment on the optimal duration of maintenance treatment in stable, remitted first-episode psychosis patients: (i) the remission period; and (ii) professionals' perceptions of relapse risk involved in medication discontinuation. The remission period was a significant predictor of the perceived relapse risk. Compared with social workers, mental health nurses perceived a higher relapse risk for patients before Bonferroni adjustment. CONCLUSIONS: The three key clinical components discussed--remission period, perceived relapse risk and perceived optimal duration of maintenance treatment--are interconnected, collectively influencing health-care professionals' attitudes towards relapse and maintenance for patients. Our study identified differences between the perceptions of nursing and social work professionals, indicating a need for communication and discussion among professional groups in order to arrive at a coherent, efficacious team consensus.
