Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In Myanmar, community health workers, known as malaria volunteers, have played a key role in reducing the malaria burden in the malaria control phase, providing essential malaria services in rural areas where the coverage of formal health services is limited. However, the community-delivered models that have worked well for malaria control may not work well for malaria elimination. In parallel with switching from interventions for malaria control to those for elimination, the motivation and social importance of malaria volunteers has declined along with the decline of the malaria burden. To sustain volunteer motivation, the social importance and effectiveness in the malaria elimination program, the Community-delivered Integrated Malaria Elimination model for Myanmar (CIME model) was developed based on global evidence and qualitative consultations with community members, leaders, volunteers and health stakeholders in Myanmar. This study will assess the level of effectiveness of the CIME model in increasing malaria testing by its application in an open cluster-randomised controlled stepped-wedge trial.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The CIME model integrates interventions for malaria, dengue, tuberculosis, childhood diarrhoea and Rapid Diagnostic Test (RDT)-negative fever. It will involve the recruitment and training of a volunteer to implement the CIME model in each village.

The primary outcome of the trial is blood examination rate as determined by number of RDTs for malaria performed per week per village. 140 villages in 8 townships across Ayeyarwaddy, Bago and Yangon Regions and Kayah State in Myanmar will be sampled at random with probability proportional to size. Study populations include villages with ICMVs who will be re-trained as CIME volunteers (intervention phase) and the community members in the service catchment areas of those volunteers. An open stepped-wedge cluster-randomised controlled trial, randomized at the volunteer level (i.e. the volunteer and the village / workplaces they service), will be conducted over 6-months to evaluate the effectiveness and cost-effectiveness of the CIME model intervention. The stepped-wedge design will comprises 24 weekly measurements of the number of malaria blood examinations performed by each village, with villages grouped into 10 blocks of 14 villages and transitioned from control to intervention phases at bi-weekly intervals following a universal two-week control period. Differences in the per weekly rate of blood examination (primary outcome), will be estimated across intervention and control phases using a generalised linear (e.g. Poisson or negative-binomial link functions) mixed modelling analytical approach with maximum likelihood estimation.

CIME intervention

Community-delivered Integrated Malaria Elimination (CIME). The CIME intervention model integrates interventions for malaria, dengue, tuberculosis, childhood diarrhoea and RDT-negative fever.

Group Type EXPERIMENTAL

Community-delivered Integrated Malaria Elimination (CIME) intervention model

Intervention Type OTHER

Malaria: Malaria Diagnosis using RDT, treatment, referral and reporting; Prevention interventions (Behavioral Change Communication, net and repellent distribution); assisting in case and foci investigation and larval source management.

Dengue: Assisting in dengue prevention; Referral of cases. Tuberculosis (TB): Detection and referral of suspected cases; Contact tracing; Directly observed treatment, short-course (DOTS) providers; defaulter tracing; follow-up sputum examinations; assisting in TB health education talks and active case detection activities.

Childhood diarrhea: Prevention; Health education and Water, sanitation and hygiene (WASH) promotion; Diagnosis and dehydration assessment; Treatment and referral; Rehydration therapy using Oral Rehydration Solution (ORS) and oral Zinc tablet; assisted referral.

RDT-negative fever: Prevention and health education; Symptomatic treatment with antipyretics and immediate assisted referral.

ICMV standard of care

Integrated Community Malaria Volunteer (ICMV) model - this is the current standard of care. This model involves malaria volunteers undertaking additional screening and referral services for a range of other diseases including: dengue, lymphatic filariasis, tuberculosis, HIV/AIDS and leprosy.
