Community-based intervention for people with schizophrenia successfully provided by supervised community health workers in a low-resource setting Harry Minas Global and Cultural Mental Health Unit, Centre for Mental Health, School of Population and Global Health, The University of Melbourne, Melbourne, Victoria, Australia; [email protected]
WHAT IS ALREADY KNOWN ON THIS TOPIC? There is a critical global shortage of specialist human resources for mental health, particularly in low-income and middle-income countries (LMICs). In settings with inadequate numbers of mental health professionals, evidence suggests that task shifting is an effective human resources strategy and that minimally trained community health workers can increase access to mental health services while maintaining or improving the quality of clinical and social outcomes.1 WHAT DOES THIS PAPER ADD? ▸ While previous studies have focused on community health treatments for people with common mental disorders, this trial focuses on the public health problem of services for people with schizophrenia in low-resource settings. ▸ The study demonstrates the impact of the intervention, particularly on disability, and assesses the additional cost of community-based care. ▸ Significant outcomes from the intervention occurred only in the site with the most limited resources, with no significant additional benefit in the better-resourced sites. LIMITATIONS ▸ The findings are limited to a subgroup with long-standing schizophrenia, with median duration of illness of 7 years. ▸ Longer follow-up is needed for an intervention focusing on people with moderate or severe schizophrenia with persistent symptoms and disability. ▸ While the additional costs of the intervention were examined, the economic benefits of reduced disability were not estimated.
can be prevented by incorporating the intervention in early intervention programmes that are being established in LMICs. ▸ Apply well-developed methods for estimating the economic benefits of reducing severity of disability as well as additional economic costs of the approach.2 Such estimates are important in LMICs with limited capacity for investment in mental health. Evidence of return on investment will strengthen mental health advocacy. ▸ Different outcomes across sites suggest the need for more reliable data on the health systems and the economic and social contexts within which the model is being applied and evaluated. COULD THESE RESULTS CHANGE YOUR PRACTICES AND WHY? This study will change my mental health system development practice in LMICs by presenting further evidence for the positive impact of community health workers. It will change the practice of psychiatrists and other specialist mental health professionals in LMICs, who currently spend a great deal of their time in direct assessment and treatment, by demonstrating the value of a stronger focus on training and supervision of community health workers. Even the modest improvements in clinical and disability outcomes demonstrated in this study strengthen the case for task shifting as a viable human resources strategy. Competing interests None.
