Design outcomes

Primary

MeasureTime frame
The infant HIV infection incidence between EPI-2 and M18

Secondary

MeasureTime frame
Interviews to explore the contextual and individual factors influencing achievement of recruiting the target population;EPI-2 attendance of mothers living with HIV compared to the number of recruited participants;Analysis of the data routinely collected on HIV negative mothers to evaluate factors related to mother’s seroconversion during breastfeeding;Interviews to evaluate which factors influencing the effectiveness of the strategy;The high risk period for HIV transmission to infants, defined by the cumulative duration when the mother's viral load is = 1000 copies/mL, and the child is not on PNP (based on registers and missed visits);The proportion of mothers with viral load < 1000 copies/mL at 18 months ;Interviews to explore factors associated with the acceptability of the PROMISE-ZERO intervention;Interviews to explore factors related to the actual delivery of the strategy proposed in the study;Lost to follow-up rate at M18 between both arms (defined as infant with no HIV rapid test at M18);Comparison of time to get the results for viral load and diagnosis in children in the 2 arms;The proportion of observed time on lamivudine (based on registers and missed visits);Direct, medical costs, direct non-medical costs, indirect costs and composite outcomes to estimate the cost-effectiveness and budget impact of the intervention;Carbon footprint of the intervention compared to the standard of care to estimate the environmental impact of the intervention;Interviews to explore setting-level factors related to program maintenance after the clinical trial
