A systematic review of health system barriers and enablers for antiretroviral therapy (ART) for HIV-infected pregnant and postpartum women
BACKGROUND: Despite global progress in the fight to reduce maternal mortality, HIV-related maternal deaths remain persistently high, particularly in much of Africa. Lifelong antiretroviral therapy (ART) appears to be the most effective way to prevent these deaths, but the rates of three key outcomes--ART initiation, retention in care, and long-term ART adherence--remain low. This systematic review synthesized evidence on health systems factors affecting these outcomes in pregnant and postpartum women living with HIV. METHODS: Searches were conducted for studies addressing the population of interest (HIV-infected pregnant and postpartum women), the intervention of interest (ART), and the outcomes of interest (initiation, adherence, and retention). Quantitative and qualitative studies published in English since January 2008 were included. A four-stage narrative synthesis design was used to analyze findings. Review findings from 42 included studies were categorized according to five themes: 1) models of care, 2) service delivery, 3) resource constraints and governance challenges, 4) patient-health system engagement, and 5) maternal ART interventions. RESULTS: Low prioritization of maternal ART and persistent dropout along the maternal ART cascade were key findings. Service delivery barriers included poor communication and coordination among health system actors, poor clinical practices, and gaps in provider training. The few studies that assessed maternal ART interventions demonstrated the importance of multi-pronged, multi-leveled interventions. CONCLUSIONS: There has been a lack of emphasis on the experiences, needs and vulnerabilities particular to HIV-infected pregnant and postpartum women. Supporting these women to successfully traverse the maternal ART cascade requires carefully designed and targeted interventions throughout the steps. Careful design of integrated service delivery models is of critical importance in this effort. Key knowledge gaps and research priorities were also identified, including definitions and indicators of adherence rates, and the importance of cumulative measures of dropout along the maternal ART cascade
The Association between Quality of HIV Care, Loss to Follow-Up and Mortality in Pediatric and Adolescent Patients Receiving Antiretroviral Therapy in Nigeria
Access to pediatric HIV treatment in resource-limited settings has risen significantly. However, little is known about the quality of care that pediatric or adolescent patients receive. The objective of this study is to explore quality of HIV care and treatment in Nigeria and to determine the association between quality of care, loss-to-follow-up and mortality. A retrospective cohort study was conducted including patients â€18 years of age who initiated ART between November 2002 and December 2011 at 23 sites across 10 states. 1,516 patients were included. A quality score comprised of 6 process indicators was calculated for each patient. More than half of patients (55.5%) were found to have a high quality score, using the median score as the cut-off. Most patients were screened for tuberculosis at entry into care (81.3%), had adherence measurement and counseling at their last visit (88.7% and 89.7% respectively), and were prescribed co-trimoxazole at some point during enrollment in care (98.8%). Thirty-seven percent received a CD4 count in the six months prior to chart review. Mortality within 90 days of ART initiation was 1.9%. A total of 4.2% of patients died during the period of follow-up (mean: 27 months) with 19.0% lost to follow-up. In multivariate regression analyses, weight for age z-score (Adjusted Hazard Ratio (AHR): 0.90; 95% CI: 0.85, 0.95) and high quality indicator score (compared a low score, AHR: 0.43; 95% CI: 0.26, 0.73) had a protective effect on mortality. Patients with a high quality score were less likely to be lost to follow-up (Adjusted Odds Ratio (AOR): 0.42; 95% CI: 0.32, 0.56), compared to those with low score. These findings indicate that providing high quality care to children and adolescents living with HIV is important to improve outcomes, including lowering loss to follow-up and decreasing mortality in this age group
Retention of mothers and infants in the prevention of mother-to-child transmission of HIV programme is associated with individual and facility-level factors in Rwanda.
OBJECTIVES: Investigate levels of retention at specified time periods along the prevention of mother-to-child transmission (PMTCT) cascade among mother-infant pairs as well as individual- and facility-level factors associated with retention.
METHODS: A retrospective cohort of HIV-positive pregnant women and their infants attending five health centres from November 2010 to February 2012 in the Option B programme in Rwanda was established. Data were collected from several health registers and patient follow-up files. Additionally, informant interviews were conducted to ascertain health facility characteristics. Generalized estimating equation methods and modelling were utilized to estimate the number of mothers attending each antenatal care visit and assess factors associated with retention.
RESULTS: Data from 457 pregnant women and 462 infants were collected at five different health centres (three urban and two rural facilities). Retention at 30 days after registration and retention at 6 weeks, 3, 6, 9 and 12 months post-delivery were analyzed. Based on an analytical sample of 348, we found that 58% of women and 81% of infants were retained in care within the same health facility at 12 months post-delivery, respectively. However, for mother-infant paired mothers, retention at 12 months was 74% and 79% for their infants. Loss to facility occurred early, with 26% to 33% being lost within 30 days post-registration. In a multivariable model retention was associated with being married, adjusted relative risk (ARR): 1.26, (95% confidence intervals: 1.11, 1.43); antiretroviral therapy eligible, ARR: 1.39, (1.12, 1.73) and CD4 count per 50 mm(3), ARR: 1.02, (1.01, 1.03).
CONCLUSIONS: These findings demonstrate varying retention levels among mother-infant pairs along the PMTCT cascade in addition to potential determinants of retention to such programmes. Unmarried, apparently healthy, HIV-positive pregnant women need additional support for programme retention. With the significantly increased workload resulting from lifelong antiretroviral treatment for all HIV-positive pregnant women, strategies need to be developed to identify, provide support and trace these women at risk of loss to follow-up. This study provides further evidence for the need for such a targeted supportive approach
A Systematic Review of Individual and Contextual Factors Affecting ART Initiation, Adherence, and Retention for HIV-Infected Pregnant and Postpartum Women
BACKGROUND: Despite progress reducing maternal mortality, HIV-related maternal deaths remain high, accounting, for example, for up to 24 percent of all pregnancy-related deaths in sub-Saharan Africa. Antiretroviral therapy (ART) is effective in improving outcomes among HIV-infected pregnant and postpartum women, yet rates of initiation, adherence, and retention remain low. This systematic literature review synthesized evidence about individual and contextual factors affecting ART use among HIV-infected pregnant and postpartum women. METHODS: Searches were conducted for studies addressing the population (HIV-infected pregnant and postpartum women), intervention (ART), and outcomes of interest (initiation, adherence, and retention). Quantitative and qualitative studies published in English since January 2008 were included. Individual and contextual enablers and barriers to ART use were extracted and organized thematically within a framework of individual, interpersonal, community, and structural categories. RESULTS: Thirty-four studies were included in the review. Individual-level factors included both those within and outside a womanâs awareness and control (e.g., commitment to childâs health or age). Individual-level barriers included poor understanding of HIV, ART, and prevention of mother-to-child transmission, and difficulty managing practical demands of ART. At an interpersonal level, disclosure to a spouse and spousal involvement in treatment were associated with improved initiation, adherence, and retention. Fear of negative consequences was a barrier to disclosure. At a community level, stigma was a major barrier. Key structural barriers and enablers were related to health system use and engagement, including access to services and health worker attitudes. CONCLUSIONS: To be successful, programs seeking to expand access to and continued use of ART by integrating maternal health and HIV services must identify and address the relevant barriers and enablers in their own context that are described in this review. Further research on this population, including those who drop out of or never access health services, is needed to inform effective implementation

National newspaper coverage of minority health disparities.
OBJECTIVES: To assess American newspaper coverage regarding racial and ethnic minority health disparities (MHDs). METHODS: LexisNexis was queried with specific word combinations to elicit all MHD articles printed in 257 newspapers from 2000-2004. The full texts were read and articles categorized by racial/ethnic group and specific MHD topics mentioned. RESULTS: In the five years from 2000-2004, 1188 MHD articles were published, representing 0.09% of all articles about health. Newspapers gave much attention to MHD when discussed in conferences and meetings and speeches by senior health officials and politicians. Cancer, cardiovascular disease and HIV/AIDS were most frequent among disease-specific mentions. Articles about African Americans comprised 60.4% of all race/ethnicity-mentioning articles. CONCLUSIONS: Despite the release of major organizational reports and the publication of many studies confirming the prevalence of MHD, few newspaper articles have been published explaining MHD to the public. Because of the general public's low rate of health literacy, the health world should collaborate with the media to present a consistent, simple message concerning gaps in care experienced by all racial/ethnic minority groups. In a time of consumer-directed healthcare, if Americans understand that MHDs exist, they may galvanize to advocate for disparity elimination and quality improvement
A Landscape Analysis of Prevention of Vertical Transmission Program Data and Interventions from Fiscal Years 2019 to 2021
INTRODUCTION: In 2020, an estimated 150,000 infants acquired HIV infection through vertical transmission. With pregnant and breastfeeding women facing numerous social and health system barriers, continuity of care for mother-infant pairs (MIPs) requires prioritized engagement for timely infant HIV testing and linkage to treatment. METHODS: PEPFAR Monitoring, Evaluation and Reporting indicators were analyzed from across 14 USAID-supported countries across three fiscal years (FYs) (October 2018 - September 2021): number of HIV-exposed infants (HEI) with a sample collected for an HIV test by two months of age; percentage of HEI who received an HIV test by two months of age (EID 2mo coverage); and final outcome status of HEIs. Qualitative information on implementation of PVT interventions was gathered via a survey disseminated to USAID/PEPFAR country teams. RESULTS: From October 2018 to September 2021, 716,383 samples were collected for infant HIV tests. EID 2mo coverage increased across the FYs from 77.3% in FY19 to 83.5% in FY21. Eswatini, Lesotho, and South Africa demonstrated the highest EID 2mo coverage across all three FYs. Burundi (93.6%), DRC (92%) and Nigeria (90%) had the highest percentage of infants with a known final HIV outcome. Qualitative survey data showed that the most implemented interventions used by the countries were mentor mothers, appointment reminders, cohort registers and joint provision of MIP services. CONCLUSIONS: Achieving eVT requires a client-centered and multi-pronged approach, typically combining several PVT interventions. Country and program implementers should utilize person-centered solutions to best target MIPs to be retained in the continuum of care
