Understanding the uptake and determinants of prevention of mother-to-child transmission of HIV services in East Africa: Mixed methods systematic review and meta-analysis. PLoS One 2024; 19:e0300606. [PMID: 38635647 PMCID: PMC11025786 DOI: 10.1371/journal.pone.0300606] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2023] [Accepted: 02/28/2024] [Indexed: 04/20/2024] Open
Abstract
BACKGROUND Prevention of mother-to-child transmission (PMTCT) of HIV service is conceptualized as a series of cascades that begins with all pregnant women and ends with the detection of a final HIV status in HIV-exposed infants (HEIs). A low rate of cascade completion by mothers' results in an increased risk of HIV transmission to their infants. Therefore, this review aimed to understand the uptake and determinants of key PMTCT services cascades in East Africa. METHODS We searched CINAHL, EMBASE, MEDLINE, Scopus, and AIM databases using a predetermined search strategy to identify studies published from January 2012 through to March 2022 on the uptake and determinants of PMTCT of HIV services. The quality of the included studies was assessed using the Mixed Methods Appraisal Tool. A random-effects model was used to obtain pooled estimates of (i) maternal HIV testing (ii) maternal ART initiation, (iii) infant ARV prophylaxis and (iv) early infant diagnosis (EID). Factors from quantitative studies were reviewed using a coding template based on the domains of the Andersen model (i.e., environmental, predisposing, enabling and need factors) and qualitative studies were reviewed using a thematic synthesis approach. RESULTS The searches yielded 2231 articles and we systematically reduced to 52 included studies. Forty quantitative, eight qualitative, and four mixed methods papers were located containing evidence on the uptake and determinants of PMTCT services. The pooled proportions of maternal HIV test and ART uptake in East Africa were 82.6% (95% CI: 75.6-88.0%) and 88.3% (95% CI: 78.5-93.9%). Similarly, the pooled estimates of infant ARV prophylaxis and EID uptake were 84.9% (95% CI: 80.7-88.3%) and 68.7% (95% CI: 57.6-78.0) respectively. Key factors identified were the place of residence, stigma, the age of women, the educational status of both parents, marital status, socioeconomic status, Knowledge about HIV/PMTCT, access to healthcare facilities, attitudes/perceived benefits towards PMTCT services, prior use of maternal and child health (MCH) services, and healthcare-related factors like resource scarcity and insufficient follow-up supervision. CONCLUSION Most of the identified factors were modifiable and should be considered when formulating policies and planning interventions. Hence, promoting women's education and economic empowerment, strengthening staff supervision, improving access to and integration with MCH services, and actively involving the community to reduce stigma are suggested. Engaging community health workers and expert mothers can also help to share the workload of healthcare providers because of the human resource shortage.

Abstract
Uptake of services and retention throughout the Prevention of Mother-to-Child Transmission continuum are necessary to achieve the goal of reducing Mother-to-Child Transmission of Human Immunodeficiency Virus (HIV). Adopting a retrospective cohort design, we tracked the uptake of services in a district hospital in Ghana from antenatal booking through to six weeks postnatal when early infant diagnosis was conducted. Of the 1252 pregnant women booked antenatally, 94.1% (n = 1178) received pre-test counselling, 96.3% (1134) opted for HIV testing and 3.8% (n = 43) women tested positive for HIV throughout the continuum. The retention rate at six weeks postpartum was 67.4%. Missed opportunities occurred throughout the programme and the highest disengagement, 58.9% (23/39) occurred antenatally. Instances of re-engagement were also recorded. Establishing measures to promote retention throughout the programme is critical to ensuring HIV-infected mothers maintain their health and their exposed newborns are HIV-free. This phase of the study provided a comprehensive view of retention in the absence of any baseline.

Abstract
BACKGROUND Maternal and infant HIV status influences the decision of BCG immunization of infants at birth. The objective of this study was to determine the HIV status of HIV-exposed infants (HEIs) by the first HIV DNA PCR test and the rate of BCG uptake among the HEIs who were confirmed HIV negative. METHODS This was a retrospective descriptive cross-sectional study involving the review of results of 99 dried blood samples (DBS) for the first HIV DNA PCR test of HEIs whose mothers were diagnosed HIV positive on presentation of the infants at first immunization visit at a Primary Health Centre from January 2018 to January 2019. RESULTS Of the 99 DBS examined, 86; 86.9% (95% CI 80.1-93.6) were HIV negative, 9; 9.1% (95% CI 3.3-14.8) were positive while the results of 4 (4.0%) infants were not in the register. Only 7; 7.1% (95% CI 1.9-12.2) of the 99 HEIs returned for BCG immunization at the centre. BCG immunization status of the HEIs after first PCR results was not significantly associated with sex of the infants or availability of phone number of the guardians (p = 0.70 and 0.12, respectively). CONCLUSION The majority of HEIs were HIV negative at first HIV DNA PCR test. Few of these HIV negative infants returned for BCG immunization. Hence, all HEIs should be given BCG immunization according to WHO GAVCS committee recommendation on BCG immunization for settings with poor HIV diagnostic and treatment facilities for mothers and infants.

Abstract
Introduction Even though advancement in mother-to-child HIV transmission prevention services is observed, many infants are lost to follow-up and could not access the full package of mother-to-child HIV transmission prevention services as a result. This is one of the obstacles to the effectiveness of the program. Therefore, determining the magnitude of lost to follow-up and its predictors is important among HIV-exposed infants. Method This institution-based retrospective cohort study was conducted from August 2013 to June 2018 at the University of Gondar Comprehensive Specialized Hospital. We retrieved charts of 423 child–mother pairs through a simple random sampling technique. Data collectors extracted data by using a data extraction tool adapted from the Ethiopian Federal Ministry of Health HIV-exposed infant follow-up form. Bivariable and multivariable Cox regression models were fitted to identify predictors of lost to follow-up. Result A total of 402 child–mother pairs were included in the study. Of the study participants, 6.0% were lost to follow-up for more than 3 months before the declaration of their HIV status. Born from rural residence mother (AHR = 3.5; 95% CI 1.549–7.894), infants whose mothers have three and more children (AHR = 3; 95% CI 1.284–6.963), and low birth weight infants (AHR = 3.2; 95% CI 1.055–9.450) were independent predictors of lost to follow-up among HIV-exposed infants. Conclusion Significant numbers of infants were unable to access full HIV diagnosis and care services as a result of loss to follow-up. Special consideration for mothers having large numbers of children, rural residence, and low birth weight infants could be an important intervention to decrease lost to follow-up.

Abstract
Introduction Complete follow-up of human immunodeficiency virus (HIV)-exposed infants (HEI) is crucial for a successful prevention of mother-to-child HIV transmission. This study analyzed the HEI follow-up and factors associated with loss to follow-up (LTFU) in southern Mozambique. Methods This retrospective cohort study used the data of HEI enrolled between June 2017 and June 2018, followed-up for 18 months. The outcomes were the proportion of infants with completed follow-up and a definitive diagnosis, and the presence of clinical events. Kaplan–Meier survival analysis was used to calculate the cumulative probability of LTFU and of clinical events. Factors associated with LTFU and clinical events were analyzed using Cox regression to calculate the hazard ratio (HR) and adjusted HR (AHR), with a 95% confidence interval (CI) and a significance cutoff of p<0.05. Results 1413 infants were enrolled (49% males) at a median age of 32 days (IQR 31–41); the median follow-up time was 12 months (IQR 8.2–14.2); 1129 (80%) completed follow-up and had a definitive diagnosis, 58 (4%) were HIV-positive, 225 (16%) were LTFU; 266 (19%) presented a clinical event. Factors associated with LTFU were: age >2 months at entry (AHR, 1.58; 95% CI, 1.12–2.23), non-exclusive breastfeeding (AHR, 1.44; 95% CI, 1.01–2.06), poor cotrimoxazole adherence (AHR, 3.42; 95% CI, 1.59–7.35), and clinical events (AHR, 0.51; 95% CI, 0.34–0.77). Factors associated with clinical events were: malnutrition (AHR, 10.06; 95% CI, 5.92–17.09), non-exclusive breastfeeding (AHR, 1.98; 95% CI, 1.34–2.93), no nevirapine prophylaxis (AHR, 1.67; 95% CI, 1.18–2.36), and poor cotrimoxazole adherence (AHR, 2.62; 95% CI, 1.10–6.22). Conclusion The high rate of HEI LTFU, associated with delayed linkage to postnatal care, poor prophylaxis adherence, non-exclusive breastfeeding, indicates the need to design a differentiated service delivery model that is tailored to the mothers’ and infants’ specific needs.

Abstract
BACKGROUND The burden of mother-to-child transmission rate of HIV is high and risk factors are common in Ethiopia. This systematic review and meta-analysis intended to provide the pooled estimation of mother-to-child transmission rate and its risk factors in Ethiopia. METHODS We searched PubMed, Google Scholar, EMBASE and Web of Science electronic databases for all available references. We included observational studies including case-control, cohort, and cross-sectional studies. The search was further limited to studies conducted in Ethiopia and publish in English. Heterogeneity was checked using the I2 statistic. Egger's test and the funnel plot were used to assess publication bias. A meta-analysis using a weighted inverse variance random-effects model was performed. RESULTS A total of 18 studies with 6253 individuals were included in this systematic review and meta-analysis. Of these, 14 studies with 4624 individuals were used to estimate the prevalence. The estimated pooled prevalence of mother-to-child transmission of HIV was 11.4% (95% CI = 9.1-13.7). The pooled adjusted odds ratio (AOR) of mother-to-child transmission of HIV for the infants from rural area was 3.8 (95% CI = 1.4 to 6.3), infants delivered at home was 3.2 (95% CI = 1.2 to 5.2), infant didn't take antiretroviral prophylaxis was 5.8 (95% CI = 1.5 to 10.3), mother didn't take antiretroviral prophylaxis was 6.1 (95% CI = 2.5 to 9.6), mothers didn't receive PMTCT intervention was 5.1 (95% CI = 1.6, 8.6), and on mixed feeding was 4.3 (95% CI = 1.8 to 6.7). CONCLUSIONS This systematic review and meta-analysis showed that mother-to-child transmission rate of HIV was high in Ethiopia. Being from the rural residence, home delivery, not taking antiretroviral prophylaxis, the absence of PMTCT intervention, and mixed infant feeding practices increased the risk of HIV transmission.

Abstract
Introduction Numerous challenges exist in provision of prevention of mother-to-child transmission of HIV (PMTCT) such as linking HIV exposed infants (HEI) and their mothers to chronic cares services, and tackling loss to follow up. Limited evidence exists in Ethiopian setting that explains the persisting high HIV infection rate among HEIs and extent of linkage to chronic care. The study assessed the proportion of HIV infection; children linked to chronic care and determinants of HIV infection among HEI in Northern Ethiopia. Methods This institution-based cross-sectional study was conducted in health centers and hospitals of Amhara Region. A total of 484 HEI-mother pairs selected by multistage random sampling were included in the study. Data were collected from PMTCT and anti-retroviral therapy (ART) clinics using pre-tested and structured questionnaires. Quantitative data were entered in Epi Info version 7.0 and exported to SPSS 20.0 for analysis. Results A total of 484 mother-infant pairs with a response rate of 92.4% were included in the analysis. About 94.2% of infants and women were linked to chronic care follow-up sometime after the diagnosis. The proportion of HIV infection was 12.4%. Antenatal care attendance had a significant association with HIV infection among HEI (p < 0.0001). Delivering in health institution (p < 0.005), mode of delivery (p < 0.032), and provision of both infant (p < 0.0001) and maternal (p < 0.0001) prophylaxis showed a highly significant association with HIV infection among HIV exposed infants. Conclusion Health facilities shall encourage antenatal care that increased institutional delivery, leads to timely initiation and high uptake of PMTCT to reduce the vertical transmission of HIV infection and meet national targets.

Longitudinal adherence to antiretroviral drugs for preventing mother-to-child transmission of HIV in Zambia. BMC Pregnancy Childbirth 2015; 15:258. [PMID: 26459335 PMCID: PMC4603915 DOI: 10.1186/s12884-015-0697-7] [Citation(s) in RCA: 34] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2015] [Accepted: 10/06/2015] [Indexed: 12/02/2022] Open
Abstract
Background Adherence to antiretroviral (ARV) drugs is essential for eliminating new pediatric infections of human immunodeficiency virus (HIV). Since the Zambian government revised the national guidelines based on option A (i.e., maternal zidovudine and infant ARV prophylaxis) of the World Health Organization’s 2010 guidelines, no studies have assessed adherence to ARVs during pregnancy up to the postpartum period. This study aimed to examine adherence to ARVs and identify the associated risk factors. Methods A prospective cohort study was conducted in the Chongwe district from June 2011 to January 2014. Self-reported adherence to ARVs was examined during pregnancy and at one week, six weeks, and 24 weeks postpartum among 321 HIV-positive women. The probability of remaining adherent to ARVs was estimated using the Kaplan-Meier method, and the risk factors for non-adherence were identified using the Cox proportional hazard regressions—treating loss to follow-up as non-adherence. The statuses of HIV in HIV-exposed infants were assessed in January 2014. Results During the study period, 326 infants were born to HIV-positive women, 262 (80.4 %) underwent HIV testing, and 11 (3.4 %) had their HIV infection detected at the time that they had the latest HIV testing as of January 2014. The ARV adherence rate was 82.5 % during pregnancy, 84.2 % at one week postpartum, 81.5 % at six weeks postpartum, and 70.5 % at 24 weeks postpartum. The probability of remaining adherent to ARVs was 0.61 at day 50, 0.35 at day 100, 0.18 at day 200, and 0.06 at day 300. Attending a referral health center (HC) was a risk factor for non-adherence compared with attending rural HCs that provided HIV care/treatment (adjusted hazard ratio [aHR] 0.71, 95 % confidence interval [CI] 0.57–0.88) and those that did not provide HIV care/treatment (aHR 0.58, 95 % CI 0.46–0.74). A new diagnosis of HIV infection compared to a known HIV-positive status before pregnancy was another risk factor for non-adherence (aHR 1.24, 95 % CI 1.03–1.50). Conclusions Maintaining adherence to ARVs through pregnancy to the postpartum period remains a crucial challenge in Zambia. To maximize the treatment benefits, adherence to ARVs and retention in care should be improved at all health facilities.

Risk of HIV and associated factors among infants born to HIV positive women in Amhara region, Ethiopia: a facility based retrospective study. BMC Res Notes 2014; 7:876. [PMID: 25475398 PMCID: PMC4289399 DOI: 10.1186/1756-0500-7-876] [Citation(s) in RCA: 35] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2013] [Accepted: 11/18/2014] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The estimated HIV prevalence among pregnant women in Ethiopia is 1.2 percent and unfortunately one of every 3 children born to these women gets infected with HIV. Elimination of these mother-to-child transmissions (MTCT) of HIV is possible through HIV testing during pregnancy and taking antiretroviral medications. However, only 24 percent of the pregnant women living with HIV have yet received the medication needed to prevent the transmission of HIV. Hence, there exists a concern that the rate of HIV infection among infants born to HIV positive mothers is increasing. This study assessed the prevalence of HIV infection and associated factors among infants born to women living with HIV, in South Gondar zone, Amhara region, Ethiopia. METHODS Facility based document review was conducted upon 434 charts. The study participants were HIV exposed infants enrolled from January to December 2012. The data were reviewed from all the 17 health facilities which were providing PMTCT services in the zone. The study included 434 HIV exposed infants having an HIV Deoxyribonucleic Acid (DNA) Polymerase Chain Reaction (PCR) test result. The data were collected using structured data extraction tool. Binary logistic regression analysis was employed to assess the putative association of independent variables with the outcome variable. Significance was taken at a P value<0.05 and 95% confidence level. RESULT The prevalence of HIV among HIV exposed infants was 10.1% (95% CI=7.3-13%). Delayed diagnosis (AOR=2.7, 95% CI=1.3, 29.4), mixed infant feeding (AOR=8.8, 95% CI=4.5, 22.8), failure to receive either antiretroviral therapy or prophylaxis during pregnancy or breast feeding (AOR=21.6, 95% CI=14.5, 39.8) and shorter duration of HIV treatment (AOR=12, 95% CI=(4.2, 45.0) were the factors that increase the risk of mother- to- child transmission of HIV. CONCLUSION The prevalence of HIV infection among HIV exposed infants is strikingly high. Inadequate use of antiretroviral therapy and skilled delivery care were the factors that enhance mother-to-child transmission of HIV. Integrated and audience specific education and promotion for seeking obstetric care and HIV services is instrumental to curb the devastating consequences of HIV on pregnant women and their newborns.

Gouveia PADC, da Silva GAP, de Albuquerque MDFPM. Predictors of loss to follow-up among children registered in an HIV prevention mother-to-child transmission cohort study in Pernambuco, Brazil.

Abstract
Background Mother-to-child transmission of HIV (MTCT) is the major form of acquiring the disease among children. The loss to follow-up (LTF) of mothers and their children is a problem that affects the effectiveness of programs for the prevention of mother-to-child transmission (PMTCT). The aim of this study is to identify risk factors associated with the LTF of HIV-exposed children in the state of Pernambuco, Brazil. Methods A retrospective cohort study was carried out with 1200 HIV-exposed children born between 2000 and 2009, registered up to the age of 2 months in a public health PMTCT program. Children were considered LTF if they did not return for scheduled visits to monitor infection status. Univariate and multivariate logistic regression analyses were conducted to identify risk factors for LTF. Results A total of 185 children (15.4%; CI: 95%: 13.4 - 17.4%) met the case definition of LTF before the determination of serological HIV status. Risk factors independently associated with LTF were mother-child pairs who reside in rural and remote areas (OR 1.86; 95% CI: 1.30-2.66) and mothers who use illicit drugs (OR 1.8; 95% CI: 1.08-3.0). Initiation of the PMTCT during pregnancy was a protective factor for LTF (OR 0.69; 95% CI: 0.49-0.96). Conclusions The decentralization of support services for HIV-exposed children to other cities in the state seems to be crucial for the accurate monitoring of outcomes. It is also important to introduce additional measures addressing mothers who are drug users so that they remain in the program: an intensive follow-up program that actively searches for absentee mother-child pairs, support from social services and treatment for drug-dependency. The findings of this study highlight the importance of diagnosing mothers as early as possible in order to conduct a more complete follow-up period of the children. Solving the above-mentioned problems is a challenge, which must be overcome so as to improve the quality of PMTCT.

Abstract
Accelerated efforts to end vertical HIV transmission have resulted in a 52% decrease in new infections among children since 2001. However, current approaches to prevent mother-to-child-transmission (PMTCT) assume a linearity and universality. These insufficiently guide clinicians and programmes toward interventions that comprehensively address the varying and changing needs of clients. This results in high levels of loss-to-follow-up at each step of the PMTCT cascade. Current PMTCT approaches must be adapted to respond to the different and complex realities of women, children and families affected by HIV. Drawing on the concept of an 'HIV trajectories,' we screened peer-reviewed literature for promising PMTCT approaches and selected 13 articles for qualitative review when the described intervention involved more than a biomedical approach to PMTCT and mother-child HIV treatment and care. Our qualitative analysis revealed that interventions which integrated elements of the 'HIV trajectories' perspective and built on people living with HIV support/network, community health worker, primary healthcare and early childhood development platforms were successful because they recognized that HIV is an illness, experienced, moderated and managed by numerous factors beyond biomedical interventions alone.On the basis of this review, we call for the adoption of an 'HIV trajectories' perspective that can help assess the comprehensiveness of care provided to women, children and families affected by HIV and can inform the planning and delivery of HIV and related services so that they more adequately respond to the varying needs of clients on different 'HIV trajectories'.

Abstract
Introduction: Although prevention of mother-to-child HIV transmission (PMTCT) programs are widely implemented, many children do not benefit from them because of loss to follow-up (LTFU). We conducted a systematic review to determine the magnitude of infant/baby LTFU along the PMTCT cascade. Methods: Eligible publications reported infant LTFU outcomes from standard care PMTCT programs (not intervention studies) at any stage of the cascade. Literature searches were conducted in Medline, Embase, Web of Knowledge, CINAHL Plus, and Maternity and Infant Care. Extracted data included setting, methods of follow-up, PMTCT regimens, and proportion and timing of LTFU. For programs in sub-Saharan Africa, random-effects meta-analysis was done using Stata v10. Because of heterogeneity, predictive intervals (PrIs; approximate 95% confidence intervals of a future study based on extent of observed heterogeneity) were computed. Results: A total of 826 papers were identified; 25 publications were eligible. Studies were published from 2001 to 2012 and were mostly from sub-Saharan Africa (three were from India, one from UK and one from Ireland). There was extensive heterogeneity in findings. Eight studies reported on LTFU of pregnant HIV-positive women between antenatal care (ANC) registration and delivery, which ranged from 10.9 to 68.1%, pooled proportion 49.08% [95% confidence interval (CI) 39.6–60.9%], and PrI 22.0–100%. Fourteen studies reported LTFU of infants within 3 months of delivery, range 4.8–75%, pooled proportion 33.9% (27.6–41.5), and PrI 15.4–74.2. Children were also lost after HIV testing; this was reported in five studies, pooled estimate 45.5% (35.9–57.6), PrI 18.7–100%. Programs that actively tracked defaulters had better retention outcomes. Conclusion: There is unacceptable infant LTFU from PMTCT programs. Countries should incorporate defaulter-tracking as standard to improve retention.
