Addressing Early Retention in Antenatal Care Among HIV-Positive Women Through a Simple Intervention in Kinshasa, DRC: The Elombe "Champion" Standard Operating Procedure

Programmatic Retention in Prevention of Mother-to-Child Transmission (PMTCT) Programs: Estimated Rates and Cofactors Using Different Nonretention Measures

BACKGROUND

Prevention of mother-to-child transmission programs serve women continuing and initiating antiretroviral therapy (ART) in pregnancy, and follow-up schedules align to delivery rather than ART initiation, making conventional HIV retention measures (assessed from ART initiation) challenging to apply. We evaluated 3 measures of peripartum nonretention in Kenyan women living with HIV from pregnancy to 2 years postpartum.

METHODS

This longitudinal analysis used programmatic data from the Mobile WAChX trial (NCT02400671). Outcomes included loss to follow-up (LTFU) (no visit for ≥6 months), incomplete visit coverage (<80% of 3-month intervals with a visit), and late visits (>2 weeks after scheduled date). Predictors of nonretention were determined using Cox proportional hazards, log-binomial, and generalized estimating equation models.

RESULTS

Among 813 women enrolled at a median of 24 weeks gestation, incidence of LTFU was 13.6/100 person-years; cumulative incidence of LTFU by 6, 12, and 24 months postpartum was 16.7%, 20.9%, and 22.5%, respectively. Overall, 35.5% of women had incomplete visit coverage. Among 794 women with 12,437 scheduled visits, a median of 11.1% of visits per woman were late (interquartile range 4.3%-23.5%). Younger age, unsuppressed viral load, unemployment, ART initiation in pregnancy, and nondisclosure were associated with nonretention by all measures. Partner involvement was associated with better visit coverage and timely attendance. Women who became LTFU had higher frequency of previous late visits (16.7% vs. 7.7%, P < 0.0001).

CONCLUSIONS

Late visit attendance may be a sentinel indicator of LTFU. Identified cofactors of prevention of mother-to-child transmission programmatic retention may differ depending on retention measure assessed, highlighting the need for standardized measures.

Firth's Logistic Regression of Interruption in Treatment before and after the Onset of COVID-19 among People Living with HIV on ART in Two Provinces of DRC

The impact of the COVID-19 pandemic extends beyond the immediate physical effects of the virus, including service adjustments for people living with the human immunodeficiency virus (PLHIV) on antiretroviral therapy (ART). Purpose: To compare treatment interruptions in the year immediately pre-COVID-19 and after the onset of COVID-19 (10 April 2020 to 30 March 2021). Methods: We analyze quantitative data covering 36,585 persons with HIV who initiated antiretroviral treatment (ART) between 1 April 2019 and 30 March 2021 at 313 HIV/AIDS care clinics in the Haut-Katanga and Kinshasa provinces of the Democratic Republic of Congo (DRC), using Firth’s logistic regression. Results: Treatment interruption occurs in 0.9% of clients and tuberculosis (TB) is detected in 1.1% of clients. The odds of treatment interruption are significantly higher (adjusted odds ratio: 12.5; 95% confidence interval, CI (8.5−18.3)) in the pre-COVID-19 period compared to during COVID-19. The odds of treatment interruption are also higher for clients with TB, those receiving ART at urban clinics, those younger than 15 years old, and female clients (p < 0.05). Conclusions: The clients receiving ART from HIV clinics in two provinces of DRC had a lower risk of treatment interruption during COVID-19 than the year before COVID-19, attributable to program adjustments.

Factors impacting antenatal care utilization: a systematic review of 37 fragile and conflict-affected situations

BACKGROUND

It is estimated that over 930 million people live in fragile and conflict-affected situations (FCAS) worldwide. These regions, characterized by violence, civil unrest, and war, are often governed by corrupt administrations who are unwilling to provide their citizens with basic human rights. Individuals living in FCAS face health inequities; however, women are disproportionally affected and face additional barriers to accessing sexual and reproductive services, including antenatal care (ANC). This systematic review aims to identify the factors that impact ANC usage in the 37 countries or regions classified as FCAS in 2020 by The World Bank.

METHODS

Using the PRISMA guidelines, a systematic search of five databases (SCOPUS, Web of Science, PubMed, EMBASE, and CINAHL) was conducted. Results were limited to human studies, written in English, and published between January 2002 and January 2022. Studies that identified factors affecting utilization of ANC or maternal health services were included for review and critically appraised using the National Institute of Health's Quality Assessment Tools. Findings were summarized using a narrative synthesis approach.

RESULTS

The database search yielded 26,527 studies. After title, abstract and full-text review, and exclusion of duplicate articles, 121 studies remained. Twenty-eight of the 37 FCAS were represented in the included studies. The studies highlighted that women in FCAS' are still not meeting the World Health Organization's 2002 recommendation of four ANC visits during pregnancy, a recommendation which has since been increased to eight visits. The most cited factors impacting ANC were socioeconomic status, education, and poor quality of ANC. Despite all studies being conducted in conflict-affected regions, only nine studies explicitly identified conflict as a direct barrier to accessing ANC.

CONCLUSION

This review demonstrated that there is a paucity in the literature examining the direct and indirect impacts of conflict on ANC utilization. Specifically, research should be conducted in the nine FCAS that are not currently represented in the literature. To mitigate the barriers that prevent utilization of maternal health services identified in this review, policy makers, women utilizing ANC, and global organizations should attempt to collaborate to enact policy change at the local level.

Predictors of retention in the prospective HIV prevention OKAPI cohort in Kinshasa

Retention is a key element in HIV prevention programs. In Sub-Saharan Africa most data on retention come from HIV clinical trials or people living with HIV attending HIV treatment and control programs. Data from observational cohorts are less frequent. Retention at 6-/12-month follow-up and its predictors were analyzed in OKAPI prospective cohort. From April 2016 to April 2018, 797 participants aged 15-59 years attending HIV Voluntary Counseling and Testing in Kinshasa were interviewed about HIV-related knowledge and behaviors at baseline and at 6- and 12-month follow-ups. Retention rates were 57% and 27% at 6- and 12-month follow up; 22% of participants attended both visits. Retention at 6-month was significantly associated with 12-month retention. Retention was associated with low economic status, being studying, daily/weekly Internet access, previous HIV tests and aiming to share HIV test with partner. Contrarily, perceiving a good health, living far from an antiretroviral center, daily/weekly alcohol consumption and perceiving frequent HIV information were inversely associated with retention. In conclusion, a high attrition was found among people attending HIV testing participating in a prospective cohort in Kinshasa. Considering the low retention rates and the predictors found in this study, more HIV cohort studies in Kinshasa need to be evaluated to identify local factors and strategies that could improve retention if needed.

A Cascade of Interventions to Promote Adherence to Antiretroviral Therapy in African Countries

Purpose of Review

We reviewed interventions to improve uptake and adherence to antiretroviral therapy (ART) in African countries in the Treat All era.

Recent Findings

ART initiation can be improved by facilitated rapid receipt of first prescription, including community-based linkage and point-of-care strategies, integration of HIV care into antenatal care and peer support for adolescents. For people living with HIV (PLHIV) on ART, scheduled SMS reminders, ongoing intensive counselling for those with viral non-suppression and economic incentives for the most deprived show promise. Adherence clubs should be promoted, being no less effective than facility-based care for stable patients. Tracing those lost to follow-up should be targeted to those who can be seen face-to-face by a peer worker.

Summary

Investment is needed to promote linkage to initiating ART and for differentiated approaches to counselling for youth and for those with identified suboptimal adherence. More evidence from within Africa is needed on cost-effective strategies to identify and support PLHIV at an increased risk of non-adherence across the treatment cascade.

Antenatal care utilization in the fragile and conflict-affected context of the Democratic Republic of the Congo

Maternal mortality represents one of the widest gaps between developed and developing countries. Ninety-nine percent of maternal deaths occur in developing countries, with over half occurring in sub-Saharan Africa. This health indicator became a global priority when the United Nations' Sustainable Development Goal 3.1 set out to decrease the global maternal mortality rate to less than 70 per 100 000 births by 2030. In the Democratic Republic of the Congo (DRC), 473 of every 100 000 women who give birth die due to pregnancy-related complications. These deaths could be prevented through enhanced access and utilization of antenatal care services and skilled birth attendants. However, amid prolonged conflict, violence, and authoritarian governments, the Democratic Republic of the Congo has been classified as a fragile and conflict-affected situation and women are prone to face difficulties accessing maternal health services. This study examined the utilization of antenatal care and skilled birth attendants in the Democratic Republic of Congo using logistic regressions. Our findings show that women living in regions with extremely high levels of prolonged conflict were significantly less likely than those in regions with moderate levels of conflict to have their first antenatal care visit within the first trimester (OR = 0.29, p < 0.01), and to have four visits (OR = 0.46, p < 0.01). Overall, women in regions with extremely high levels of conflict (OR = 0.41, p < 0.01) were less likely to meet the World Health Organization's antenatal care recommendations compared to those in regions with moderate levels of conflict. The findings suggest that conflict-affected countries, such as the Democratic Republic of the Congo, require context-specific interventions if progress is to be made towards achieving Sustainable Development Goal 3.1.

Shifting to the long view: engagement of pregnant and postpartum women living with HIV in lifelong antiretroviral therapy services

Introduction: The advent of policies promoting lifelong antiretroviral therapy (ART) for all pregnant and postpartum women living with HIV has shifted focus from short-term prevention of mother-to-child transmission (PMTCT) to lifelong engagement in ART services. However, disengagement from care threatens the long-term treatment and prevention benefits of lifelong ART. Areas covered: A framework for considering the unique aspects of ART for pregnant and postpartum women is presented along with a review of the literature on maternal engagement in care in sub-Saharan Africa and a discussion of potential interventions to sustain engagement in lifelong ART. Expert opinion: Engaging women and mothers in ART services for life is critical for maternal health, PMTCT, and prevention of sexual transmission. Evidence-based interventions exist to support engagement in care but most focus on periods of mother-to-child transmission risk. In the long term, life transitions and health-care transfers are inevitable. Thus, interventions that can reach beyond a single facility or provide a bridge between health services should be prioritized. Multicomponent interventions will also be essential to address the numerous intersecting barriers to sustained engagement in ART services.
