The Impact of Mentor Mothers on PMTCT Service Outcomes in Nigeria (MoMent)

• Proportion of HIV-exposed infants presenting for DNA PCR testing by 2 months of age. [ Time Frame: At 2 months (62 days) of age for the HIV-exposed infant. ]
  Early infant diagnosis (EID) is defined as the collection and processing of an HIV DNA PCR test for an HIV-exposed infant by 2 months of age. EID is done to ensure that HIV-positive infants will be promptly enrolled into HIV treatment programs and can start lifesaving Antiretroviral Therapy (ART) in timely fashion.
  
  
• Proportion of HIV-positive mothers retained in PMTCT care at 6 months post-delivery. [ Time Frame: At 180 days (6 months) post-delivery ]
  Maternal retention is determined by evaluating for at least 1 clinic visit made for each 30-day period for the first 180 days postpartum. The proportion of women making at least 3 of 6 monthly appointments are designated retained; this proportion is calculated for each study arm.
  
  

• Maternal viral suppression at 6 months postpartum [ Time Frame: 6 months (169 to 197 days) post-delivery ]
  Proportion of HIV-positive mothers with undetectable viral load (<20 copies/ml), measured at 6 months postpartum.
  
  
• Proportion of infants HIV-positive at 2 and 6 months post-delivery. [ Time Frame: At 2 months (62 days) and at 6 months (197 days) post-delivery. ]
  All exposed infants who tested positive by DNA-PCR at 6 - 8 weeks of age and at 6 months are included in analysis for "early" MTCT and "late" MTCT, respectively. Any infants testing positive at first/early DNA PCR are excluded for testing at 6 months of age.
  
  
• Proportion of HIV-positive mothers retained in PMTCT care at 12 months post-delivery. [ Time Frame: At 360 days (12 months) post-delivery ]
  Maternal retention is determined by evaluating for at least 1 clinic visit made for each 30-day period for the first 360 days postpartum. The proportion of women making at least 6 of 12 monthly appointments are designated retained; this proportion is calculated for each study arm.
  
  

Nigeria has had a national HIV/AIDS care and treatment program in place since 2003. Included in this national program are prevention programs; the largest of which is the prevention-of-mother-to-child transmission (PMTCT) program. Despite more than 10 yrs of providing PMTCT, Nigeria still has significant problems with uptake of, and retention in these services. Only 30% of HIV-positive pregnant women receive HIV drugs for both treatment and prophylaxis, and Nigeria has an estimated 41,000 new child infections annually, the highest of any country in the world.

Mentor Mothers (MM) are women living with HIV who are experienced users and navigators of HIV services, particularly PMTCT. Public health interventions engaging MM to support other HIV-positive women for linkage and retention in PMTCT and treatment services has been tested in South Africa, and has been adopted and applied in several other African countries. Similar MM programs have also been adopted and implemented in Nigeria since 2007; however, objective evaluations of MM impact on PMTCT service uptake and retention have not been performed to date.

While MM and similar peer support interventions have shown some success in other African countries, their implementation between and within countries has not been standardized. Incremental impact may be gained with more structured, objective-specific MM programming and service delivery.

The MoMent (MOther MENTor) is an implementation research study that is evaluating the impact of structured vs routine peer support on PMTCT outcomes in Nigeria, focusing on two North-Central states, the Federal Capital Territory and Nasarawa. The intervention consists of a simple but detailed standardized training curriculum for MMs coupled with daily MM supervision by dedicated personnel as well as standardized, user-friendly tools for both MMs and their supervisors to use for service delivery. These trained MM, along with trained MM Supervisors, form the basis of the Mentor Mother Intervention package. The choice of rural areas served by Primary Healthcare Centers is due to the fact that PMTCT coverage and uptake is lowest in these areas; the study sites are located in hard-to-reach-areas where a significant number of PMTCT-eligible clientele live.
