말라위에서 모자간 HIV 전파를 근절하기 위한 차별화된 현장 진료 활성 사례 찾기 및 관리 모델 평가 (PAC-Man)

2026년 9월 17일 업데이트: University of North Carolina, Chapel Hill

UNCPM 22401 - 말라위 릴롱웨와 망고치에서 HIV 모자 전파 근절을 위한 차별화된 현장 진료 활성 사례 찾기 및 관리 모델 평가

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

  1. Estimate the effect of the PAC-Man model, compared to SOC, on the proportion of infants who receive timely EID testing.
  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. Compare implementation outcomes between the PAC-Man model and SOC.

Participants: The total study sample size is 2,426, including 2,304 mother-infant pair (MIP) survey participants, 48 high-risk pregnant/breastfeeding women living with HIV for in-depth interviews (from high-risk MIPs who participated in a survey); 10 PMTCT policy makers and Ministry of Health (MOH)/ President's Emergency Plan for AIDS Relief (PEPFAR) implementing partner senior managers for key informant interviews; and about 48-64 professional and lay health providers for focus group discussions and implementation actor surveys.

To rigorously evaluate the PAC-Man model, investigators will use a hybrid (type 3) effectiveness-implementation incomplete stepped-wedge trial design. The hybrid incomplete stepped-wedge design is a rigorous quasi-experimental design that allows for incremental "rollout" of the PAC-Man model and serial measurement of both health outcomes (for infants and mothers in Objectives 1 and 2, respectively), as well as implementation outcomes (Objective 3). The incomplete stepped-wedge design is more efficient than a complete design, minimizes costs, and reduces participant burden, without sacrificing statistical precision. Using this design, sequential crossover from control (i.e., the SOC) to intervention (i.e., SOC plus the PAC-Man model) takes place at each 'step' using cluster randomization until all clusters (defined as a group of "sites," or health facilities plus the surrounding communities in its catchment area) receive the intervention. The 12 sites included in our study will be divided into 4 clusters of 3 sites each.

상세 설명

PAC-Man Model:

PAC-Man represents an integrated differentiated services delivery (DSD) model for mothers and infants that brings the following three evidence-based practices into the community for elimination of mother to child transmission (EMTCT): 1) pediatric active case finding using novel point-of-care (POC) early infant diagnosis (EID) technology; 2) same-day antiretroviral therapy (ART) initiation for infants newly diagnosed with HIV infection; and 3) maternal viral load (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 in which the mother living with HIV did not initiate ART, started ART late during pregnancy or breastfeeding, dropped off treatment following ART initiation, was unsuppressed on ART, was identified with HIV infection for the first-time during the post-partum period, and/or did not return with her infant for EID testing. Because these evidence-based practices are already recommended by the Ministry of Health and will be functioning at the site and not the individual level, 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.

PAC-Man Implementation Approaches:

The overall implementation strategy being evaluated in this study is the creation of mobile care teams to deploy m-PIMA™ and provide EMTCT services in the community. Complementing this overarching strategy will be two sub-strategies used to enhance PAC-Man adoption: 1) task shifting of active case finding, EID and mVL testing, ART initiation, and back-to-care services to community health workers (CHWs), community nurses, and HIV diagnostic assistants; and 2) changing service sites to convenient locations in the community to overcome barriers to EID and mVL delivery. These strategies are intended to work in concert with the above evidence-based practices to integrate PAC-Man into the EMTCT program.
