The specialist model of care has been demonstrated to be acceptable and associated with improved clinical outcomes for persons with SMD engaged in the service in Ethiopia thus making this an appropriate comparison model against which to evaluate non-inferiority of the task sharing model.\n\nMethods Setting Meskan and Mareko districts, Gurage Zone, and Silti Zone, Southern Nations, Nationalities and People's Region, Ethiopia.\n\nDesign A parallel group, randomized, single-blinded, controlled non-inferiority trial.\n\nParticipants Adults (aged between 25 and 65 years) with severe mental disorders (DSM-IV diagnoses of schizophrenia or schizoaffective disorder, bipolar disorder or major depressive disorder) of a severity requiring continuing care who were (1) identified during a population-based survey carried out between 1998 and 2001, and are still under active follow-up, or (2) recruited from Butajira hospital psychiatric outpatient clinic.\n\nParticipants will be recruited and randomised in two phases. Phase 1 will include participants who are clinically stable, not pregnant or breastfeeding, not on depot medication and who have no co-morbid substance use or complex medical conditions. After a three month evaluation period, and if no safety or quality issues arise, the study will proceed to Phase 2. Phase 2 will include participants who have more complex needs or are less clinically stable.\n\nNew intervention Participants in the new intervention arm will receive a task sharing model of locally-delivered mental health care integrated into PHC. The intervention will be offered for 18 months.\n\nComparison intervention Participants in the active control arm will receive the established model of specialist mental health care delivered by psychiatric nurses at an out-patient clinic within Butajira general hospital and supported by outreach from project workers.\n\nGeneral objective To determine the acceptability, affordability, effectiveness and sustainability of mental health care for persons with SMD delivered by trained and supervised non-specialist, primary health care workers compared with an existing psychiatric nurse-led service.\n\nSpecific objectives For persons suffering from SMD in Butajira, Ethiopia,\n\n1. To determine the effectiveness and cost-effectiveness of task sharing mental health care with PHC, compared to psychiatric nurse-led mental health care, on the primary outcome measure of symptom severity and on a series of secondary outcome measures.\n2. To examine factors influencing the implementation of the task sharing intervention and future scale up, by examining feasibility, sustainability, quality, and safety, and by qualitative exploration of the experience of task sharing from the perspectives of both PHC workers and patients.\n\nHypothesis Persons with SMD who receive mental health care task-shared with PHC will have a non-inferior clinical outcome, defined as a difference in the mean symptom score on the Brief Psychiatric Rating Scale, expanded version (BPRS-E), of no more than six points higher, compared to persons with SMD who receive a psychiatric nurse-led model of mental health care, after 12 months of care under the comparison service models.\n\nSample size A total of 324 participants (162 in each arm) will be required to detect a six point higher mean BPRS-E score in the new intervention arm compared to the active control arm, at 90% power and 95% confidence, allowing for 30% refusals and loss to follow-up (n = 124 for Phase 1 and n = 200 for Phase 2).\n\nRandomisation Sequence generation: Computerized generation of randomization list. Blocked randomization stratified by health centre catchment area.\n\nAllocation concealment: Labelled, sealed envelopes containing cards with intervention allocation administered by an independent clinician.\n\nImplementation: Enrollment will occur after participants have been screened for eligibility, given informed consent (or permission given by guardian) and undergone baseline evaluation. After enrollment, an independent clinician will inform the participant of their allocation status.\n\nConcealment Partial concealment. Outcome assessment and data analysis will be carried out by investigators who are masked to the intervention allocation of participants.\n\nStatistical methods Intention to treat will be the primary approach to data analysis, but per protocol analyses will also be used as this is thought to more conservative in the case of non-inferiority trials. The primary outcome measure will be analysed using linear regression adjusting for baseline symptom severity measured using BPRS-E."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '25 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion criteria for phase 1\n\n* Participant in the ongoing Butajira SMD cohort study (at baseline (between 1998 and 2001), cohort participants were aged between 15 and 49 years, resident in the area for at least six months and had a DSM-IV (SCAN) diagnosis of schizophrenia or schizoaffective disorder, bipolar disorder or major depressive disorder)\n* Ongoing need for continuing mental health care due to:\n\n 1. being on psychotropic medication at assessment or,\n 2. not on medication but symptomatic at the time of assessment, or\n 3. have experienced partial or full relapse within the two years preceding the assessment\n* Stable clinical condition: either in remission from SMD or with residual symptoms that have been stable over the preceding three months.\n* Planning to stay resident in the area for 18 months.\n* Able to communicate in Amharic, the official language of Ethiopia.\n* Willing to be randomised to either of the service models as described in the protocol.\n* Has capacity to consent to participation or permission given by guardian and not refusing to participate\n* Resident in catchment area of TaSCS health centres (excluding Butajira health centre)\n\nExclusion criteria for phase 1\n\n* Suicide attempt within the preceding three months\n* Current active suicide intent\n* Prescribed Thioridazine, Valproate, Lithium or second generation antipsychotic medications (Risperidone and Olanzapine), as these medications are not be available in psychiatric nurse-led units or PHC settings in Ethiopia.
