Home-Based Intervention for the Prevention and Treatment of Malaria Among Children Younger Than 5 Years in the West Region of Cameroon: Protocol for a Randomized Controlled Trial
Bibliographic record
Abstract
BACKGROUND: Although malaria is preventable and curable, 1 child dies of this disease every 2 minutes in Africa. Home-based management of malaria reduces the progression of severe malaria by more than 50%. Scalable, efficacious, and cost-effective strategies are needed to empower the capacities of home caregivers of children younger than 5 years of age in health education, diagnosis, and treatment of malaria at home. OBJECTIVE: The main objective of this trial is to assess the impact of the management provided by home caregivers on the prevention, diagnosis, and treatment of malaria in children younger than 5 years as compared to the home-based malaria management component of the integrated community-directed intervention (CDI) strategy of community health workers (CHWs). METHODS: A randomized controlled trial will be conducted. CHWs have conducted a census of all households where there is at least one child younger than 5 years with their home caregivers. These children and their home caregivers have been randomly placed into the intervention or control groups among the households identified. The trial will allow malaria home-based prevention, diagnosis, and treatment of 350 children younger than 5 years old by home caregivers in the Fombap area (intervention group) where the integrated CDI strategy will not implemented. This group will be compared to the home-based malaria management component of the integrated CDI strategy in which 350 children in the same age group will be followed up by CHWs in the Baneghang area (control group). The primary outcomes will be the prevention, diagnosis, and treatment of malaria in children younger than 5 years of age by home caregivers at home. The secondary outcomes comprise the malaria follow-up indicators produced by home caregivers in the intervention group and those produced by CHWs in the control group. Both descriptive and one-way analysis of variance estimation techniques will be used to compare the mean difference in the 2 strategies. RESULTS: From September 2019 to October 2019, all home caregivers with children younger than 5 years of age were identified in the intervention and control group by CHWs. Following this, 203 home caregivers with their 350 children younger than 5 years were randomly selected and enrolled in the intervention group, while 225 home caregivers with their 350 children younger than 5 years were enrolled in the control group. In the intervention group, 203 home caregivers were trained in November 2019. This home treatment effectively started in December 2019 and will continue until May 2020. CONCLUSIONS: Findings from this randomized controlled trial will contribute to resolving the challenges of severe malaria and to limiting the death due to malaria of children younger than 5 years. This will bring benefits to home caregivers who will know how to promptly diagnose and properly treat malaria in their children at home.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
