Design outcomes

Primary

MeasureTime frame
Safety outcomes: 1.Incidence of serious adverse events (SAE) and adverse events (AE) within 7-14 days of study drug administration. AMR outcomes: Phenotypic macrolide resistance among Streptococcus pneumoniae, K. pneumoniae, and S. aureus in the nasopharyngeal samples and E. coli, Salmonella spp. and Shigella spp strains isolated from stool samples among 1-11 month-old children, at 0, 6, 12, 18 and 24 months during MDA.

Secondary

MeasureTime frame
Mortality outcome: Mortality (deaths / 1000 years at risk) among children who were 1-11 months old at the time of study drug administration, based on a birth history approach or similar as used in routine population-based surveys such as Demographic Health Surveys. Cost and cost-effectiveness outcomes: Cost per child treated and cost per death averted. Cost data will be collected following an ingredients approach, based on a semi-structured questionnaire and by consultation of the programme accounting system. The work will also present an analysis of the full cost of scaled programme in all high-mortality states in Nigeria. Feasibility and acceptability outcomes: A qualitative evaluation will seek to identify and describe key assumptions and conditions underlying the implementation, sustainability and scaling-up of the different delivery approaches. Investigation will focus on (i) feasibility, including a situation and stakeholder analysis of the structural, organizational and management factors that enhance or constrain effective implementation, and (ii) community acceptability
