Evaluation of human immunodeficiency virus-adapted group prenatal care

Optimal utilization of prevention of mother-to-child transmission of HIV services among adolescents under group versus focused antenatal care in Eastern Uganda

BACKGROUND

Group antenatal care (G-ANC), an alternative to focused ANC (F-ANC), involves grouping mothers by gestational and maternal age. In high-income countries, G-ANC has been associated with improved utilization of health care services like Prevention of Mother to Child Transmission (PMTCT) of HIV services. Some low-resource countries with poor utilization of health care services have piloted G-ANC. However, there is limited evidence of its efficiency. We, therefore, compared G-ANC versus F-ANC with regards to optimal utilization of PMTCT of HIV services and assessed associated factors thereof among adolescent mothers in eastern Uganda. We defined optimal utilization of PMTCT of HIV services as the adolescent being up to date with HIV counseling and testing. If found HIV negative, subsequent timely re-testing. If found HIV positive, initiation of antiretroviral therapy (ART) under option B plus for the mother. While for the infant, it entailed safe delivery, testing, feeding, and appropriate HIV chemotherapy.

METHODS

From February to April 2020, we conducted a cross-sectional study among 528 adolescent mothers in four sites in eastern Uganda. We assessed the optimal utilization of PMTCT of HIV services among adolescent mothers that had attended G-ANC versus F-ANC at the post-natal care or immunization clinics. We also assessed the factors associated with optimal utilization of PMTCT of HIV services among these mothers.

RESULTS

Optimal utilization of PMTCT was higher among those in G-ANC than in F-ANC (74.7% vs 41.2, p-0.0162). There was a statistically significant association between having attended G-ANC and optimal utilization of PMTCT [PR = 1.080, 95%CI (1.067-1.093)]. Other factors independently associated with optimal utilization were; having a partner that tested for HIV [PR = 1.075, 95%CI (1.048-1.103)], trimester of first ANC visit: second trimester [PR = 0.929, 95%CI (0.902-0.957)] and third trimester [PR = 0.725, 95%CI (0.616-0.853)], and the health facility attended: Bugembe HCIV [PR = 1.126, 95%CI (1.113-1.139)] and Jinja regional referral hospital [PR = 0.851, 95%CI (0.841-0.861].

CONCLUSIONS

Adolescent mothers under G-ANC had significantly higher optimal utilization of PMTCT of HIV services compared to those under F-ANC. We recommend that the Ministry of Health considers widely implementing G-ANC, especially for adolescent mothers.

HIV-Adapted Group Prenatal Care: Assessing Viral Suppression and Postpartum Retention in Care

Viral suppression and postpartum retention in care have far-reaching health implications for pregnant women living with HIV and their children, yet remain public health challenges. Prenatal care presents a unique opportunity to engage pregnant women in care. The purpose of this study is to evaluate whether group prenatal care is effective in impacting these outcomes for pregnant women living with HIV. A retrospective cohort study was performed of all women living with HIV who obtained prenatal care from a community-based health center between 2013 and 2019. Women who spoke English or Spanish, remained within the system, and had not participated in group prenatal care previously were included. Women self-selected a prenatal care model: 85 selected group care and 109 elected individual care. Group prenatal care followed a standard Centering Pregnancy^® curriculum with the addition of HIV-related topics. The primary outcomes of the study were viral suppression (viral load <20 copies/mL) and postpartum retention in care (attending at least one or two visits with HIV primary care within 12 months postpartum). After adjusting for potential confounding factors, women who participated in group prenatal care were significantly more likely to have at least one HIV primary care visit postpartum {adjusted odds ratio (aOR) = 2.71 [95% confidence interval (CI 1.14-6.46)]; p = 0.024}, and had a trend for achieving viral suppression by the time of delivery [aOR = 2.29 (95% CI 0.94-5.55); p = 0.068]. We have demonstrated that group prenatal care for pregnant women living with HIV is feasible and effective, with positive impacts on retention in care and viral suppression, factors that affect long-term outcomes from patients living with HIV.
