Child Health, Implementation, Mortality
Conditions
Brief summary
This cluster-randomized trial aims to compare the impact of different delivery approaches to azithromycin distribution on coverage, costs, and feasibility outcomes. The investigators hypothesize that door-to-door delivery will have higher coverage and costs and similar feasibility and acceptability compared to fixed-point delivery.
Detailed description
Azithromycin distribution has been shown to reduce mortality in children 1-59 months. This trial aims to contribute evidence on viable approaches to implementation as high mortality countries consider this intervention to improve child survival. From a pool of eligible rural and peri-urban communities in the Dosso Region in Niger, 80 will be randomly selected and randomized to receive door-to-door or fixed-point delivery of a single dose of azithromycin distribution to children 1-59 months of age via community health workers biannually. Treatment coverage, costs and cost-effectiveness, and feasibility and acceptability will be compared by arm.
Interventions
Azithromycin will be administered as a single dose in oral suspension form for children as follows: * Single-dose of 20mg/kg in children (up to the maximum adult dose of 1g) * For children 1 to \<12 months of age, weight-based dosing will be used * For children 12 to 59 months of age, height-based dosing will be used via height-stick approximation as currently performed by Niger's trachoma program.

Masking description
In the delivery trial, participants, implementers, and outcome assessors will not be actively masked from the delivery approach given the nature of the intervention.
Intervention model description
The AVENIR delivery trial is a two-armed, cluster-randomized trial in the Dosso region in Niger. 80 Communities will be randomized in a 1:1 allocation to either door-to-door delivery or fixed-point delivery of azithromycin to children 1-59 months of age.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Treatment Coverage | 6 months | Treatment coverage as defined by the number of doses of azithromycin administered in each community divided by the total eligible population |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Fidelity of intervention rollout | 6 months | Fidelity of intervention rollout reported as the percent of protocol steps with complete adherence by the field team |
| Acceptability of intervention | 6 months | Participant and provider perception of acceptability of delivery approaches as measured by surveys conducted post-distribution |
| Program Costs | 6 months | Program costs as captured by routine administrative data collection during the study period and by micro-costing activities |
