Title: Evaluating the Impact of a Community Health Worker Program in Neno, Malawi: A Stepped-Wedge Cluster Randomized Controlled Trial
Brief Summary: This protocol concerns the implementation and evaluation of an intervention designed to realign the existing cadre of Community Health Workers (CHW) in Neno District, Malawi to better support the care needs of the clients they serve. The proposed intervention is a 'Household Model' where CHWs will be assigned to households, rather than HIV or TB specific patients, and will be trained to provide support for a wider range of conditions including HIV, hypertension, diabetes, and pediatric malnutrition. The new model is designed to improve retention in care for clients with chronic, non-communicable diseases, along with increased uptake of women's health services and treatment for pediatric malnutrition, while sustaining the high retention rates for clients in the HIV program. Eleven sites (health centres and hospitals) were arranged into six clusters by estimated size of the catchment area populations, with a population range of 11,680 to 26,260 and an average population of 20,400. The order in which the intervention will be rolled out across the sites will be randomized so that the intervention can be evaluated in a stepped-wedge cluster randomized controlled trial. These clusters were grouped based mostly on geographic location but also on catchment area sizes, in order to maximize feasibility of training for the CHW team and not overload CHW training sessions with too many trainees.


Options:
A: Inclusion Criteria:

* Reproductive age women (aged 15-49 years)
* Permanently living in the study area
* No plans to leave the study area in the subsequent three years
* Written informed consent is obtained

Exclusion Criteria:

* Non-permanent community members (i.e. seasonal migrants)
* Plans to leave study area in the subsequent three years
B: Inclusion Criteria:

* Resident of one of the 11 catchment areas
* Seeks routine health care from a health facility in Neno District

Exclusion Criteria:

* Not a resident and/or does not reside predominantly in Neno District
C: Inclusion criteria for phase 1

* 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)
* Ongoing need for continuing mental health care due to:

  1. being on psychotropic medication at assessment or,
  2. not on medication but symptomatic at the time of assessment, or
  3. have experienced partial or full relapse within the two years preceding the assessment
* Stable clinical condition: either in remission from SMD or with residual symptoms that have been stable over the preceding three months.
* Planning to stay resident in the area for 18 months.
* Able to communicate in Amharic, the official language of Ethiopia.
* Willing to be randomised to either of the service models as described in the protocol.
* Has capacity to consent to participation or permission given by guardian and not refusing to participate
* Resident in catchment area of TaSCS health centres (excluding Butajira health centre)

Exclusion criteria for phase 1

* Suicide attempt within the preceding three months
* Current active suicide intent
* 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. Within the Butajira SMD cohort, only people who have received care from psychiatrist-led units in the capital city, Addis Ababa, might be receiving these medications. At present, fewer than 10 patients are known to be taking one of these medications.
* Prescribed depot medication
* Complex or unstable medical condition interfering with management of psychiatric disorder or requiring ongoing medical treatment from Butajira hospital
* Alcohol or khat dependence or abuse within the last 12 months
* Pregnant or breast-feeding
* Restrained at home
* Refusing to participate in the study

Inclusion criteria for Phase 2 As for Phase 1, but if we are unable to recruit enough participants from the existing Butajira SMD cohort then we will expand recruitment to people with SMD attending the psychiatric out-patient clinic at Butajira hospital. A semi-structured diagnostic interview will be carried out to determine diagnostic eligibility (DSM-IV diagnosis of schizophrenia or schizoaffective disorder, bipolar disorder or major depressive disorder). For participants recruited from Butajira hospital psychiatric out-patient clinic, the minimum age will be 25 years and the participants should have had their first contact with specialist mental health services at least two years prior to recruitment into the trial to ensure comparability with the Butajira SMD cohort sample.

Exclusion criteria for Phase 2

* Current active suicide intent
* Prescribed Thioridazine, Valproate, Lithium or second generation antipsychotic medications (Risperidone and Olanzapine).
* Pregnant or breast-feeding and prescribed depot
* Refusing to participate in the study
* Medical condition requiring ongoing medical treatment from Butajira hospital
D: Inclusion Criteria:

* children aged 06-59 months at the time of the study
* children who live in a village in the health district participating in the study

Exclusion Criteria:

* children whose legal guardian refuses to participate in the study
