NCT06493357

Brief Summary

Purpose: To conduct a hybrid effectiveness-implementation stepped-wedge trial to:

  1. 1.Estimate the effect of the PAC-Man model, compared to SOC, on the proportion of infants who receive timely EID testing.
  2. 2.Estimate the effect of the PAC-Man model, compared to SOC, on the proportion of pregnant and breastfeeding women living with HIV who receive guideline-adherent viral load testing.
  3. 3.Compare implementation outcomes between the PAC-Man model and SOC.

Outcome Measures

  • Proportion of high-risk infants who receive EID testing by age 6 months

    Within 12 months of MIP enrollment in the national EMTCT program

  • Proportion of infants who initiate ART

    Within 12 months of MIP enrollment in the national EMTCT program

  • +20 more secondary outcomes

Study Arms (2)

PAC-Man Model

EXPERIMENTAL

PAC-Man represents an integrated DSD model for mothers and infants that brings the following three evidence-based practices into the community for EMTCT: 1) pediatric active case finding using novel POC EID technology; 2) same-day ART initiation for infants newly diagnosed with HIV infection; and 3) mVL testing and back-to-care services. PAC-Man uses a mobile approach to offer EMTCT services in the community and reach "high risk" MIPs. Delivering the PAC-Man model will be done under the auspices of routine care, applying an overarching implementation strategy of creating new mobile care teams equipped with new diagnostic technology who deploy the m-PIMA in community settings.
