An interventional study of Task-shifting to lower-cadre providers at PMTCT sites and POC CD4+ cell count testing in Suspected Damage to Fetus From Viral Disease in the Mother and HIV, sponsored by Vanderbilt University. Completed at 12 sites in 2 countries. Per ClinicalTrials.gov, last updated 2016-11-02.
Sponsored by Vanderbilt University · Not applicable, Interventional, and Prevention
Each year, an estimated 230,000 HIV-infected women in need of services for prevention of mother-to-child transmission of HIV (PMTCT) give birth in Nigeria, more than in any other nation in the world. Vanderbilt University (VU), through its affiliate, Friends in Global Health (FGH), is currently supporting HIV/AIDS services in North-Central Nigeria. These sites are predominantly rural primary health centers (PHCs) where shortages of high-cadre health care providers and insufficient laboratory capacity to perform CD4+ cell count testing have been major barriers to effective PMTCT scale-up. A systematic reassignment of patient care responsibilities coupled with the adoption of point-of-care (POC) CD4+ cell count testing will facilitate the ability of lower-cadre health providers to manage PMTCT care, including the provision and scale-up of antiretroviral treatment (ART) to pregnant women in these rural, decentralized sites. A system wherein men are facilitated to accompany their wives to ANC appointments will create an important opportunity to address entrenched gender norms. The investigators therefore propose using community and facility-based measures to encourage male partners to accompany their spouses for ANC. As influential community members, male partners can assist their spouses to utilize culturally-sensitive, sustainable and integrated PMTCT care provided by lower-cadre providers in these resource-constrained settings.
The investigators propose a parallel, cluster randomized trial to evaluate the impact of a family-focused PMTCT package that includes: 1) task-shifting to lower-cadre providers at PMTCT sites; 2) POC CD4+ cell count testing; (3) integrated mother-infant care; and (4)) a prominent role for influential family members (male partners), working in close partnership with community-based health workers/volunteers. The specific aims of this study are:
In addition, two qualitative evaluations will be conducted in order to:
The investigators propose a parallel cluster randomized trial to evaluate the effects of the intervention. Twelve primary and secondary level health care facilities in Niger State will be randomized to the control (standard-of-care) or intervention arms. The investigators will match clinics on patient volume and level of facility and randomize to intervention and standard-of-care/control arms - 6 clinics per arm.
The investigators will make the proposed intervention available to all eligible women attending clinics that are randomized to the intervention arm. The drug regimens and general HIV care services provided as part of the package are standard of care, based on Nigerian national guidelines.
Inclusion Criteria: (1) HIV-infected women (and their infants) who present to ANC or delivery with unknown HIV status; (2) HIV-infected women (and their infants) with previous history of ARV prophylaxis or treatment, but who are not on prophylaxis or treatment at the time of presentation for antenatal care or delivery.
Exclusion Criteria: HIV-infected women with known status who are on ARV prophylaxis or treatment at the time of presentation to ANC.
Home-based care (HBC) workers will track clients who miss appointments at control and intervention sites. The HBC workers will document clients as terminated care if they: (1) discontinued services due to death or personal decision; (2) transferred their care to another clinic; or (3) are lost to follow-up (defined as being 90 days late for a clinic appointment plus 5 failed attempts at tracking the client). Clients will not receive any remuneration for participating in the study. Clients will be allowed to discontinue participation and decide that their medical data cannot be used in the analysis.

Intervention package includes: 1) task-shifting to lower-cadre providers at PMTCT sites; 2) POC CD4+ cell count testing; (3) integrated mother-infant care; and (4) a prominent role for influential family members (male partners), working in close partnership with community-based health workers/volunteers. Patients attending sites randomized to this arm will also receive group health education; opt-out HIV testing, same-day HIV test results; infant feeding counseling; HBC services; infant prophylaxis, early infant diagnosis, and linkage to family spacing services, if desired.
Other: Task-shifting to lower-cadre providers at PMTCT sites · Other: POC CD4+ cell count testing · Other: integrated mother-infant care · Other: Prominent role for influential family members (male partners) in collaboration with CHWs
Arm will receive standard of care activities, namely: group health education; opt-out HIV testing, same-day HIV test results; infant feeding counseling; HBC services; infant prophylaxis, early infant diagnosis, linkage to family spacing services, if desired.
Proportion of eligible pregnant women who initiate ART for purposes of PMTCT
The primary outcome is the proportion of eligible women who initiate ARV medications for PMTCT. This will be determined through data in our electronic medical records system. The investigators will report the total proportion of women who initiate ARV drugs, presenting the results stratified by regimen (cART, ZDV, NVP) and type of facility. The investigators will also collect information on duration of cART.
Time frame: 18 months
Postpartum retention of mother-infant pairs at 6 and 12 weeks post delivery
Mother-infant pairs who have presented for their 6-week postpartum appointment will be considered active in the program (retained in care). The investigators will assess retention at both 6 week and 12-week time points in order to examine the impact of our intervention package on early (6 week) and later (12-week) postpartum retention.
Time frame: 12 weeks
HIV-free infant survival at 6 weeks postpartum
The study is not adequately powered to test this outcome.
Time frame: 6 weeks post delivery
Cost effectiveness analysis of impact of integrated PMTCT package
For the CEA, the basic outcome is the cost-effectiveness ratio (CER). The CER will be computed for both intervention and the standard-of-care arms. The investigators will also measure the incremental cost-effectiveness ratio (ICER). A separate ICER will be calculated for the two primary study outcomes (the cost/HIV-infected women who initiated treatment for PMTCT and the cost/mother-infant pair retained in care at 6 weeks postpartum) and for the secondary outcome (cost per infant infection averted at 6 weeks of age).
Time frame: 18 months
Plan to share: No — IPD will not be available to other researchers.
