Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The investigators hypothesize that a strategy of establishing facility-based mother support groups (MSGs) for HIV-positive mothers will result in increased retention rates of HIV-exposed infants in clinic-based PMTCT follow-up systems twelve months post-delivery compared to clinics that lack MSGs. The study will be conducted in health facilities in rural Mutare and Makoni health districts in Manicaland province, Zimbabwe. A two-arm cluster controlled study design will be used in 30 rural clinics randomly assigned to either arm to compare the effectiveness of MSGs. Arm 1 of the study consists of standard of care whilst arm 2 consists of standard of care together with facility-based MSGs.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

PRIMARY OBJECTIVE To test whether MSGs lead to increased retention of HIV-exposed infants in PMTCT programmes

SECONDARY OBJECTIVES

1. To assess whether MSGs lead to increased retention of mothers in postnatal HIV follow-up care
2. To assess whether male participation in PMTCT activities is increased at clinics with MSGs
3. To assess whether selected maternal and infant health indicators are improved in HIV-positive mothers and their exposed infants at facilities with MSGs, viz. (1) Antenatal attendance; (2) Delivery in facilities; (3) Infant immunisation uptake; (4) Infant feeding methods and nutrition status; (5) Infant nevirapine prophylaxis; (6) Infant co-trimoxazole prophylaxis; (7) Infant HIV testing; and (8) Family planning uptake

MOTHER SUPPORT GROUP INTERVENTION MSGs were designed following formative research. A non-governmental organisation established MSGs by recruiting HIV+ mothers and volunteer coordinators (MSGCs) prior to commencing enrolment. MSGCs were HIV-positive mothers who were trained in MSG establishment and maintenance, retention activities and data collection. MSGs meet each two weeks with the MSGC or health worker facilitating an information session using a curriculum of eight PMTCT-related topics. MSGCs send standard message reminders to members, contact non-attending members by phone and inform health workers (HWs) to assist retention. HWs conduct retention actions of non-attending patients in PMTCT programmes.

SAMPLE SIZE AND RANDOMISATION We excluded from the study low-volume facilities that recorded booking fewer than 10 HIV-positive antenatal mothers per annum. We randomly selected facilities in the two study districts to either of the study arms. Based on estimated infant retention rates for control and intervention arms, we calculated the minimum sample size of 10 HIV-positive mothers to be enrolled at each health facility.

DATA COLLECTION, ANALYSIS AND QUALITY ASSURANCE The study utilizes the existing health information system (e.g. antenatal care (ANC) Register, Exposed Infant Follow-Up Register, Anti-retroviral treatment (ART) Register), supplemented by EPAZ study-related data collection and patient tracking systems. Study staff will work with clinic- and district-level staff to improve and collect routine and study-specific data. Data will be entered, coded, cleaned and locked before analyses are made. Data will be analysed on an intention-to-treat basis. A mobile team of well-trained quality assurance and control study staff will be deployed throughout the data collection period to ensure quality of the intervention and of data generated and collected at each study site. A pre-specified proportion of patient visit records will be reviewed from each site.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Mother support groups for HIV+ mothers

Facility-based mother support groups (MSGs) for HIV+ mothers. MSGs were established prior to study enrolment. MSGs are facilitated by volunteer mothers. Groups meet every two weeks. Health information is provided by health workers during MSGs. Mothers receive HIV prevention, psychosocial and treatment support, reinforce safe feeding practices, promote linkages with family planning services and support disclosure by HIV+ mothers to partners, male attendance and male HIV treatment. Mothers leave MSGs 6 months postnatally. Volunteer MSG coordinators contact defaulting mothers visits using cell phones; VHWs may conduct home visits to to defaulting MSG members to reduce LTFU;

Standard of Care Arm

Standard of Care: Nurses may identify HIV+ mothers lost to follow-up (LTFU); village health workers (VHWs) may conduct home visits to reduce LTFU of HIV+ mothers. LTFU activities are not standardised throughout all Ministry of Health and Child Care facilities.
