Preventing mother-to-child transmission of HIV in resource-limited settings

Process Evaluation of Prevention of Mother-to-Child Transmission of HIV Service at Gondar City Administration Governmental Health Facilities, Northwest Ethiopia: A Mixed Approach Case Study Evaluation Design

INTRODUCTION

Mother-to-child HIV transmission (MTCT), or vertical transmission of HIV, is one mode of HIV transmission from mother to baby during pregnancy, delivery and after childbirth. The continuation of new pediatric HIV infection due to the improper prevention of MTCT is a challenge in developing countries; however, the program is not evaluated yet in Ethiopia. Therefore, this study was aimed to assess the process of PMTCT service implementation status.

OBJECTIVE

This evaluation study evaluated the implementation of process levels and identified problems of PMTCT service at Gondar city administration governmental health facilities.

METHODS

A case study evaluation design with a mixed method was conducted from March to May 2020. A systematic random sampling technique was used to select participants. Data were collected using an interviewer-administered questionnaire and document review, observation, and key informant interviews. Collected data were entered using EPI data version 7 and analyzed using SPSS version 25.

RESULTS

The study found that, generally, the PMTCT program implementation was complying with the Ethiopian national guidelines by 78.32%. All facilities had most of the minimum required resources recommended by the guidelines by 75%. The services required to be provided by the facilities were highly accommodated by 90.18%, acceptable by 77.2%, with 78% compliance. Trained human resources and continuous supply of material are the main gaps.

CONCLUSION

The overall level of program implementation was judged to be good. However, there is a need for improvements such as ensuring the privacy of counselling rooms, availability of human, test kits, guidelines, beds, waiting areas, drugs, and refresher training for provider. Also, counsellors should record properly the services provided to clients in their cards, such as counselling sessions.

Tracing defaulters in HIV prevention of mother-to-child transmission programmes through community health workers: results from a rural setting in Zimbabwe

Introduction

High retention in care is paramount to reduce vertical human immunodeficiency virus (HIV) infections in prevention of mother-to-child transmission (PMTCT) programmes but remains low in many sub-Saharan African countries. We aimed to assess the effects of community health worker–based defaulter tracing (CHW-DT) on retention in care and mother-to-child HIV transmission, an innovative approach that has not been evaluated to date.

Methods

We analyzed patient records of 1878 HIV-positive pregnant women and their newborns in a rural PMTCT programme in the Tsholotsho district of Zimbabwe between 2010 and 2013 in a retrospective cohort study. Using binomial regression, we compared vertical HIV transmission rates at six weeks post-partum, and retention rates during the perinatal PMTCT period (at delivery, nevirapine [NVP] initiation at three days post-partum, cotrimoxazole (CTX) initiation at six weeks post-partum, and HIV testing at six weeks post-partum) before and after the introduction of CHW-DT in the project.

Results

Median maternal age was 27 years (inter-quartile range [IQR] 23 to 32) and median CD4 count was 394 cells/µL³ (IQR 257 to 563). The covariate-adjusted rate ratio (aRR) for perinatal HIV transmission was 0.72 (95% confidence intervals [95% CI] 0.27 to 1.96, p=0.504), comparing patient outcomes after and before the intervention. Among fully retained patients, 11 (1.9%) newborns tested HIV positive. ARRs for retention in care were 1.01 (95% CI 0.96 to 1.06, p=0.730) at delivery; 1.35 (95% CI 1.28 to 1.42, p<0.001) at NVP initiation; 1.78 (95% CI 1.58 to 2.01, p<0.001) at CTX initiation; and 2.54 (95% CI 2.20 to 2.93, p<0.001) at infant HIV testing. Cumulative retention after and before the intervention was 496 (85.7%) and 1083 (87.3%) until delivery; 480 (82.9%) and 1005 (81.0%) until NVP initiation; 303 (52.3%) and 517 (41.7%) until CTX initiation; 272 (47.0%) and 427 (34.4%) until infant HIV testing; and 172 (29.7%) and 405 (32.6%) until HIV test result collection.

Conclusions

The CHW-DT intervention did not reduce perinatal HIV transmission significantly. Retention improved moderately during the post-natal period, but cumulative retention decreased rapidly even after the intervention. We showed that transmission in resource-limited settings can be as low as in resource-rich countries if patients are fully retained in care. This requires structural changes to the regular PMTCT services, in which community health workers can, at best, play a complementary role.

Towards a family-centered approach to HIV treatment and care for HIV-exposed children, their mothers and their families in poorly resourced settings

This article provides a summary of emerging psychosocial evidence relevant to the success of comprehensive family-centered approaches to HIV prevention, treatment, care and support programs in poorly resourced settings. This report synthesizes current evidence on maternal, paternal and family experiences of HIV prevention, diagnosis, treatment, adherence and disclosure, with special focus on HIV-infected mothers and HIV-exposed children. Taking a developmental approach, we explore the current challenges and opportunities towards a family-centered approach within the continuum of HIV treatment and care, beginning in pregnancy and following the course of childhood. The discussion is limited to early and middle childhood and excludes discussion of special issues emergent in adolescence, which would warrant discussion outside the scope of this article. Attention is drawn to the complexity of problems arising within the family context and the need for improvements in the integration of aspects of treatment, care and support. While this article focuses on examples from sub-Saharan Africa, the lessons learnt and future challenges outlined are applicable to most low- and middle-income countries, and to poorly resourced contexts in higher-income countries.

Project Masihambisane: a cluster randomised controlled trial with peer mentors to improve outcomes for pregnant mothers living with HIV

BACKGROUND

Pregnant women living with HIV (WLH) face daily challenges maintaining their own and their babies' health and mental health. Standard Prevention of Maternal to Child Transmission (PMTCT) programs are not designed to address these challenges.

METHODS/DESIGN

As part of a cluster randomized controlled trial, WLH are invited to attend four antenatal and four postnatal small group sessions led by a peer WLH (a Peer Mentor). The WLH and their babies are assessed during pregnancy and at one week, six months, and twelve months post-birth. Mobile phones are used to collect routine information, complete questionnaires and remain in contact with participants over time. Pregnant WLH (N = 1200) are randomly assigned by clinic (N = 8 clinics) to an intervention program, called Masihambisane (n = 4 clinics, n = 600 WLH) or a standard care PMTCT control condition (n = 4 clinics; n = 600 WLH).

DISCUSSION

Data collection with cellular phones are innovative and effective in low-resource settings. Standard PMTCT programs are not designed to address the daily challenges faced by WLH; Peer Mentors may be useful in supporting WLH to cope with these challenges.
