A systematic review of individual and contextual factors affecting ART initiation, adherence, and retention for HIV-infected pregnant and postpartum women

Migration and first-year maternal mortality among HIV-positive postpartum women: A population-based longitudinal study in rural South Africa

BACKGROUND

In South Africa, within-country migration is common. Mobility affects many of the factors in the pathway for entry to or retention in care among people living with HIV. We characterized the patterns of migration (i.e., change in residency) among peripartum women from rural South Africa and their association with first-year postpartum mortality.

METHODS AND FINDINGS

All pregnant women aged ≥15 years were followed-up during pregnancy and the first year postpartum in a population-based longitudinal demographic and HIV surveillance program in KwaZulu-Natal, South Africa, from 2000 to 2016. During the household surveys (every 4-6 months), each household head was interviewed to record demographic components of the household, including composition, migration, and mortality. External migration was defined as moving (i.e., change in residency) into or out of the study area. For women of reproductive age, detailed information on new pregnancy and birth was recorded. Maternal death was ascertained via verbal autopsy and HIV status at delivery via annual HIV surveys. We fitted mixed-effects Cox regression models adjusting for multiple pregnancies per individual. Overall, 19,334 women had 30,291 pregnancies: 3,339 were HIV-positive, 10,958 were HIV-negative, and 15,994 had unknown HIV status at delivery. The median age was 24 (interquartile range: 20-30) years. During pregnancy and the first year postpartum, 64% (n = 19,344) and 13% (n = 3,994) did not migrate and resided within and outside the surveillance area, respectively. Of the 23% who had externally migrated at least once, 39% delivered outside the surveillance area. Overall, the mortality rate was 5.8 per 1,000 person-years (or 831 deaths per 100,000 live births) in the first year postpartum. The major causes of deaths were AIDS- or tuberculosis-related conditions both within 42 days of delivery (53%) and during the first year postpartum (62%). In this study, we observed that HIV-positive peripartum women who externally migrated and delivered outside the surveillance area had a hazard of mortality more than two times greater (hazard ratio = 2.74; 95% confidence interval 1.01-7.40, p-value = 0.047)-after adjusting for age, time period (before or after 2010), and sociodemographic status-compared to that of HIV-positive women who continuously resided within the surveillance area. Study limitations include lack of data on access to antiretroviral therapy (ART) care and social or clinical context at the destinations among mobile participants, which could lead to unmeasured confounding. Further information on how mobile postpartum women access and remain in care would be instructive.

CONCLUSIONS

In this study, we found that a substantial portion of peripartum women moved within the country around the time of delivery and experienced a significantly higher risk of mortality. Despite the scale-up of universal ART and declining trends in maternal mortality, there is an urgent need to derive a greater understanding of the mechanisms underlying this finding and to develop targeted interventions for mobile HIV-positive peripartum women.

"It was my obligation as mother": 18-Month completion of Early Infant Diagnosis as identity control for mothers living with HIV in Kenya

RATIONALE

Early Infant Diagnosis (EID) is critical to timely identification of HIV and rapid treatment initiation for infants found to be infected. Completing the EID cascade involves a series of age-specific tests between birth and 18 months and can be challenging for mother- infant pairs in low-resource settings. Even prior to recent increases in Kenya's testing recommendations, approximately 22% of mother-infant pairs enrolled in EID were lost to follow-up. As EID cascades become increasingly complex, identifying strategies to maximize retention becomes even more essential. Despite ongoing health system improvements, we still lack a framework for understanding the individual-level, psychosocial processes underlying EID completion-insight that could be essential for shaping strategies to support patients and close gaps in retention.

OBJECTIVE

Our objective was to explain individual-level processes that lead to EID completion among mothers who successfully completed the EID cascade.

METHODS

Using qualitative methods informed by grounded theory, we conducted 65 interviews with Kenyan mothers who completed EID.

RESULTS

We identified three themes related to completion: (1) Negative motivation, from the consequences of infant infection, fear of postnatal transmission, and burden of maternal failure; (2) Positive motivation, from achieving a final goal, responding to provider support, and maximizing infant health; and (3) Overcoming challenges, through resolve/resiliency, planning/privatizing and rejecting stigma/leveraging support.

CONCLUSION

Overall, the EID cascade served as a framing process for women to secure an identity as a good mother. Successful EID completion was the product of a strong motivational foundation channeled into strategies to surmount persistent challenges. Participant accounts of overcoming challenges highlight their resiliency as well as the outstanding need to address financial, logistical, and social barriers to care. Future EID programs may capitalize on these findings by affirming patients' quest for identity control, leveraging positive motivators, and expanding peer support structures to help mothers feel connected throughout the cascade.

Impact of HIV-Status Disclosure on HIV Viral Load in Pregnant and Postpartum Women on Antiretroviral Therapy

BACKGROUND

HIV-status disclosure is widely encouraged by counseling services, in part because it is thought to improve antiretroviral therapy (ART) adherence and thus HIV viral suppression. However, few longitudinal studies have examined the impact of disclosure on HIV viral load (VL) during pregnancy and postpartum.

METHODS

We explored these associations among 1187 women living with HIV, enrolled between March 2013 and June 2014 in Cape Town, South Africa.

RESULTS

Among women who tested HIV-positive before pregnancy, we observed no association between disclosure and VL at entry into antenatal care among those already on ART, nor at delivery and 12 months postpartum among those initiating ART. Among women who tested HIV-positive during pregnancy and initiated ART subsequently, disclosure to a male partner was associated with a reduced risk of VL ≥50 copies/mL at delivery (adjusted risk ratio: 0.56; 95% confidence interval: 0.31 to 1.01). After stratification by relationship status, this association was only observed among women who were married and/or cohabiting. In addition, disclosure to ≥1 family/community member was associated with a reduced risk of VL ≥50 copies/mL at 12 months postpartum (adjusted risk ratio: 0.69; 95% confidence interval: 0.48 to 0.97) among newly-diagnosed women.

CONCLUSIONS

These findings suggest that the impact of disclosure on VL is modified by 3 factors: (1) timing of HIV diagnosis (before vs. during the pregnancy); (2) relationship to the person(s) to whom women disclose; and (3) in the case of disclosure to a male partner, relationship status. Counseling about disclosure may be most effective if tailored to individual women's circumstances.

Testing Positive and Disclosing in Pregnancy: A Phenomenological Study of the Experiences of Adolescents and Young Women in Maseru, Lesotho

The routine antenatal screening through the prevention of mother to child transmission of HIV (PMTCT) services results in pregnancy being often the point at which an HIV diagnosis is made. Disclosure to partners presents particular complexities during pregnancy. However, research on the pattern and experiences of disclosure in pregnancy is limited in Lesotho, despite the high prevalence of HIV among pregnant women. The aim of this study was to explore and describe the disclosure experiences of adolescent girls and young women (AGYW) after receiving a positive HIV test result during pregnancy. Methods. Descriptive phenomenology using semistructured in-depth interview was used to collect data from AGYM sampled purposively from PMTCT sites located in urban areas of Maseru, Lesotho. Data analysis was inductive and followed the thematic approach. Findings. There were 15 AGYW involved in this study with the mean age of 20 years. Fourteen reported being pregnant with their first child and perceived HIV testing in antenatal care as compulsory. Ten AGYM disclosed their HIV status in the immediate posttesting period to protect their partners from HIV infection. The narratives revealed that the AGYM hoped that after disclosing, the partner would be tested for HIV. Furthermore, the AGYM disclosed because they wanted freedom to take their medication. Their experience of disclosure was relief, as they did not have to hide their HIV status. The AGYM reported being supported to adhere to medication and clinic attendance by their partners who also provided emotional support to them to deal with being HIV positive and pregnant. Conclusion. The AGYM recounted an overall positive experience of disclosure to their partners who agreed to test for HIV and adopted safe sex practices. This has positive implications for the PMTCT programme and the involvement of men in reproductive health. Therefore, there is need to integrate disclosure and partner testing interventions in the cascade of services in PMTCT programmes.

Acceptability of Interventions to Improve Engagement in HIV Care Among Pregnant and Postpartum Women at Two Urban Clinics in South Africa

INTRODUCTION

Pregnant women initiating antiretroviral therapy (ART) in sub-Saharan Africa have been shown to have sub-optimal engagement in care, particularly after delivery, and interventions to improve engagement in care for this unique population are urgently needed.

METHODS

We enrolled 25 pregnant women living with HIV at each of two large antenatal clinics in Johannesburg and Cape Town, South Africa (n = 50), and conducted in-depth interviews. We assessed participants' reported acceptability of the following proposed interventions to improve engagement in care and retention monitoring data systems: financial incentives, educational toys, health education, combined maternal/infant visits, cell phone text reminders, mobility tracking, fingerprint/biometric devices, and smartcards.

RESULTS

Acceptability overall for interventions was high, with mixed responses for some interventions. Overall themes identified included (i) the intersection of individual and facility responsibility for a patient's health, (ii) a call for more health education, (iii) issues of disclosure and concerns about privacy, and (iv) openness to interventions that could improve health systems.

DISCUSSION

These findings provide insight into the preferences and concerns of potential users of interventions to improve engagement in HIV care for pregnant women, and support the development of tools that specifically target this high-risk group.

Incidence and predictors of lost to follow-up among women under Option B+ PMTCT program in western Ethiopia: a retrospective follow-up study

Objective

Although Ethiopia has been implementing Option B+ program, LTFU of women from the Option B+ program is one of the challenges that minimizes its implementation. Thus, this study assessed the incidence and predictors of LTFU among women under Option B+ PMTCT program in western Ethiopia. An institution-based retrospective follow-up study was conducted. A cox proportional hazards regression model was fitted to identify predictors of LTFU. A Hazard ratios with 95% confidence CI was computed and all predictors that were associated with the outcome variable at p-value ≤ 0.05 in the multivariable cox proportional hazards were declared as a significance predictor of the outcome.

Results

A total of 330 women were followed for a mean follow up time of 16.9 (± 7.6) months. An overall incidence rate of LTFU was 9/1000 person-months. Women’s educational status, residence, HIV-disclosure status, the status of women at enrollment, previous history of HIV and ART adherence were significant predictors of LTFU. The incidence of LTFU from Option B+ PMTCT is lower as compared to evidence from sub-Saharan African and strengthening linkage and referral system between clinics as well as establishing appropriates tracing mechanisms would retain pregnant women in the program.

Combination antiretroviral treatment use in prevention of mother-to-child transmission programmes: 6-week HIV prevalence and relationship to time of antiretroviral treatment initiation and mixed feeding

Background

In Zimbabwe, 16% of pregnant women aged 15-49 years are infected with HIV. More than 90% of HIV infection in children is through mother-to-child transmission (MTCT). We investigated the effectiveness of the Option B+ in reducing HIV infection and factors associated with HIV transmission among infants born to mothers enrolled in the prevention of mother-to-child transmission (PMTCT) programme.

Methods

We randomly selected 1204 early infant HIV diagnosis test results for HIV-exposed infants and linked these results to maternal clinical records at primary healthcare clinics in Harare to estimate the prevalence of MTCT and to determine the clinical factors associated with MTCT of HIV at 6 weeks.

Results

Of the 1204 infants in the study, 2.5% (95% confidence interval [CI], 1.7-3.5) were infected with HIV at 6 weeks post-delivery. Antiretroviral adherence reduced the odds of HIV infection by about 99% (odds ratio [OR] 0.01 [95% CI, 0.00-0.06]). Both mixed feeding (OR 3.89 [95% CI, 0.92-16.50]) and late initiation of antiretroviral treatment (ART) (after delivery) (OR 3.18 [95% CI, 0.42-23.94]) increased the odds of HIV infection.

Conclusion

Early initiation of combination ART reduces 6-week MTCT of HIV in PMTCT programmes to levels similar to those found in controlled trial settings. Exclusive breastfeeding remains important even in the presence of ART.

Decreases in Self-Reported ART Adherence Predict HIV Viremia Among Pregnant and Postpartum South African Women

INTRODUCTION

Routine HIV viral load (VL) monitoring is recommended for patients on antiretroviral therapy, but frequent VL testing, required in pregnant and postpartum women, is often not feasible. Self-reported adherence can be valuable, but little is known about its longitudinal characteristics.

METHODS

We followed women living with HIV from antiretroviral therapy initiation in pregnancy through 18-month postpartum in Cape Town, South Africa, with repeated measurement of VL and self-reported adherence using a 3-item scale. We used generalized estimating equations [with results presented as odds ratios (ORs) with 95% confidence intervals (CIs)] to investigate the association between viremia and change in adherence over pairs of consecutive visits.

RESULTS

Among 2085 visit pairs from 433 women, a decrease in self-reported adherence relative to the previous visit on any of the 3 self-report items, or the combined scale, was associated with VL >50 and >1000 copies per milliliter. The best-performing thresholds to predict VL >50 copies per milliliter were a single-level decrease on the Likert response item "how good a job did you do at taking your HIV medicines in the way that you were supposed to?" (OR 2.08, 95% CI: 1.48 to 2.91), and a decrease equivalent to ≥5 missed doses or a one-level decrease in score on either of 2 Likert items (OR 1.34, 95% CI: 1.06 to 1.69).

CONCLUSIONS

Longitudinal changes in self-reported adherence can help identify patients with viremia. This approach warrants consideration in settings where frequent VL monitoring or other objective adherence measures are not possible.

Evaluation of a health system intervention to improve virological management in an antiretroviral programme at a municipal clinic in central Durban

BACKGROUND

With the largest antiretroviral therapy (ART) programme globally, demand for effective HIV management is increasing in South Africa. While viral load (VL) testing is conducted, VL follow-up and management are sub-optimal.

OBJECTIVES

The objective of this study was to address gaps in the VL cascade to improve VL testing and management.

METHODS

Antiretroviral therapy records were sampled for an in-depth review. The study team then reviewed individual records, focusing on ART management, virological suppression and retention. Multifaceted interventions focused on virological control, including a clinical summary chart for ART care; streamlining laboratory results receipt and management; monitoring VL suppression, flagging virological failure and missed visits for follow-up; down-referral of stable patients eligible for the chronic club system; and training of personnel and patients.

RESULTS

Pre-intervention, 78% (94/120) of eligible patients had VL tests, versus 92% (145/158) post-intervention (p = 0.0009). Pre-intervention, 59% (71/120) of patients accessed their VL results, versus 86% (136/158) post-intervention (p < 0.0001). Post-intervention, 73% (19/26) of patients eligible for ART change were appropriately managed, versus 11% (4/36) pre-intervention (p < 0.0001). Only 27% had no regimen changes (7/26) post-intervention, versus 81% (29/36) pre-intervention (p < 0.0001).

CONCLUSION

Service delivery was streamlined to facilitate HIV services by focusing on VL test monitoring, protocol training and accessibility of results, thereby improving clinical management.

HIV status disclosure patterns and male partner reactions among pregnant women with HIV on lifelong ART in Western Kenya

Disclosure of HIV status to sexual partners in the context of prevention of mother-to-child transmission (PMTCT) may contribute to improved PMTCT outcomes. We administered a questionnaire to 200 women with HIV enrolled in a PMTCT study during pregnancy at 12 months after birth in Western Kenya between May-September 2017. Descriptive analysis of disclosure patterns and multivariate analysis of factors associated with male partner reactions is presented. Among 180 (90%) women who reported having a male partner, 95.5% reported disclosing their HIV status to that partner. The majority of women (82.8%) reported disclosure occurred within one year of their diagnosis, with 62.7% occurring within one week. The most common forms of disclosure were: self-disclosure (55.4%), during couple's HIV testing and counseling (CHTC) (31.5%), or at an antenatal care visit (7.7%). Most women (87.5%) reported that male partner reactions to their HIV status disclosure were positive. Those with negative reactions reported their partners were confused, annoyed, or threatened to leave, however there were no reports of intimate partner violence (IPV) or break ups. Disclosure via CHTC was associated with a positive male partner reaction compared to self-disclosure (adjusted OR (aOR) 20.2, 95% Confidence Interval (CI) 1.8-221.4). Those in concordant HIV status partnerships were more likely to have a positive reaction (aOR. 6.7, 95% CI 1.7-26.6). Women experiencing frequent verbal IPV were less likely to report a positive response (aOR 0.21, 95%CI 0.1-0.8). Most postpartum women with HIV in this cohort had disclosed to their male partners early after diagnosis and experienced a positive reaction. However, a minority had still not disclosed by 12 months after the birth and some experienced negative reactions to disclosure. The form of status disclosure and impact of intimate partner violence should be given greater attention within the context of PMTCT.

Men diagnosed with HIV face gender-related barriers to initiating and adhering to antiretroviral therapy (ART). This qualitative study (73 in-depth interviews; 28 focus group discussions), conducted with men in three urban sites in Côte d'Ivoire in 2016, examined perceptions of ART, including benefits and challenges, to explore how ART mitigates HIV's threats to men's sexuality, economic success, family roles, social status, and health. Participants perceived that adhering to ART would reduce risk of transmitting HIV to others, minimize job loss and lost productivity, and help maintain men's roles as decision makers and providers. ART adherence was thought to help reduce the threat of HIV-related stigma, despite concerns about unintentional disclosure. While ART was perceived to improve health directly, it restricted men's schedules. Side effects were also a major challenge. Social and behavior change approaches building on these insights may improve male engagement across the HIV care continuum.

Slow Acceptance of Universal Antiretroviral Therapy (ART) Among Mothers Enrolled in IMPAACT PROMISE Studies Across the Globe

The PROMISE trial enrolled asymptomatic HIV-infected pregnant and postpartum women not eligible for antiretroviral treatment (ART) per local guidelines and randomly assigned proven antiretroviral strategies to assess relative efficacy for perinatal prevention plus maternal/infant safety and maternal health. The START study subsequently demonstrated clear benefit in initiating ART regardless of CD4 count. Active PROMISE participants were informed of results and women not receiving ART were strongly recommended to immediately initiate treatment to optimize their own health. We recorded their decision and the primary reason given for accepting or rejecting the universal ART offer after receiving the START information. One-third of participants did not initiate ART after the initial session, wanting more time to consider. Six sessions were required to attain 95% uptake. The slow uptake of universal ART highlights the need to prepare individuals and sensitize communities regarding the personal and population benefits of the "Treat All" strategy.

Why did I stop? And why did I restart? Perspectives of women lost to follow-up in option B+ HIV care in Dar es Salaam, Tanzania

Background

Despite an increased uptake of option B+ treatment among HIV- positive pregnant and breastfeeding women, retaining these women in care is still a major challenge. Previous studies have identified factors associated with loss to follow-up (LTFU) in HIV care, however, the perspectives from HIV-positive pregnant and breastfeeding women regarding their LTFU in option B+ needs further exploration. We explored reasons for LTFU and motivation to resume treatment among HIV-positive women initiated in option B+ in an Urban setting.

Methods

A descriptive qualitative study was conducted at three public care and treatment clinics (CTC) (Buguruni health center, Sinza hospital, and Mbagala Rangitatu health center) in Dar es Salaam, Tanzania between February and May 2017. In-depth interviews were conducted with 30 HIV-positive pregnant and breastfeeding women who were lost to follow up in the option B+ regimen. Analysis of data followed content analysis that was performed using NVivo 10 computer-assisted qualitative data analysis software.

Results

Eleven women were lost to follow-up and did not resume Option B+, while 19 had resumed treatment. The study indicated a struggle with long term disease amongst HIV-positive pregnant and breastfeeding women initiated in option B+ treatment. The reported reasons contributing to LTFU among these women appeared in three categories. The contribution of LTFU in the first category namely health-related factors included medication side effects and lack of disease symptoms. The second category highlighted the contribution of psychological factors such as loss of hope, fear of medication side effects and HIV-related stigma. The third category underscored the influence of socio-economic statuses such as financial constraints, lack of partner support, family conflicts, non-disclosure of HIV-positive status, and religious beliefs. Motivators to resume treatment after LTFU included support from health care providers and family members, a desire to protect the unborn child from HIV-infection and a need to maintain a healthy status.

Conclusion

The study has highlighted the reasons for LTFU and motivation to resume treatment among women initiated in Option B+. Our results provide further evidence on the need for future interventions to focus on these factors in order to improve retention in life-long treatment.

Engaging the capacity of comadronas as HIV prevention providers in rural Guatemala

In this study the author address rural Guatemala's poor maternal health and HIV status by integrating an effective evidence-based HIV intervention (SEPA), with local implementing health partners to extend the capacity of comadronas (traditional Mayan birth attendants) to encompass HIV prevention. I employed a multi-method design consisting of a focus group, an interview, and participant observation to identify important factors surrounding comadrona receptivity towards expanding their capacity to HIV prevention. I analyzed data using thematic analysis and identified four categories: Project logistics, HIV knowledge and risk assessment, condom perceptions, and HIV testing perceptions. I affirm comadrona receptivity toward HIV prevention, and that will guide future cultural adaptation and tailoring of SEPA for comadrona training. I will use my results to create a prototype intervention that could be applied to other similarly underserved indigenous communities.

A Systematic Review and Meta-analysis of Antiretroviral Therapy (ART) Adherence Interventions for Women Living with HIV

A systematic review and meta-analysis was conducted to determine the efficacy of women-focused ART adherence interventions. Included studies (a) reported on a behavioral ART adherence intervention for cis-women living with HIV, (b) measured ART adherence as an outcome, and (c) employed a randomized controlled trial design. Thirteen studies were included in the meta-analysis. Overall, interventions significantly improved ART adherence compared to control conditions (random-effects d = 0.82, 95% CI [0.18, 1.45], p = 0.01), however, this was largely driven by two studies that had effect sizes greater than 3 standard errors above the mean effect size. Key moderators were location, recruitment method, group-based intervention, and alteration of the healthcare system. Innovative behavioral interventions that focus on young women and adolescents, target the critical periods of pregnancy and postpartum and test the integration of multiple levels of intervention to create lasting effects on ART adherence are needed.

Severe menopausal symptoms associated with reduced adherence to antiretroviral therapy among perimenopausal and menopausal women living with HIV in Metro Vancouver

OBJECTIVES

Although more women living with HIV (WLWH) are entering midlife, the experiences of perimenopausal and menopausal WLWH, including the effects of menopausal symptoms severity, remain understudied. This study longitudinally investigated the correlates of antiretroviral therapy (ART) adherence among perimenopausal and menopausal WLWH from Metro Vancouver.

METHODS

Analyses drew on longitudinal data (2014-2017) from Sexual health and HIV/AIDS: Women's Longitudinal Needs Assessment, an ongoing community-based cohort of WLWH, aged 14+, from Metro Vancouver, Canada. At baseline and biannually, participants completed an interviewer-administered questionnaire. Bivariate and multivariable logistic regression with generalized estimating equations were used to identify the correlates of self-reported <95% ART adherence.

RESULTS

The sample included 109 perimenopausal and menopausal WLWH (233 observations), with a median age of 49 years (IQR 44-53). Whereas most (68.8%) participants experienced menopausal symptoms, only 17% had received treatment (eg, antidepressants, hormone therapy) at baseline. In multivariable analysis, severe menopausal symptoms (adjusted odds ratio [AOR] 1.03, 95% confidence interval [CI] 1.00-1.06), injection drug use (AOR 2.86, 95% CI 1.44-5.55), and physical/sexual violence (AOR 2.33, 95% CI 1.02-5.26) independently and positively correlated with <95% adherence.

CONCLUSIONS

These findings suggest that menopausal symptoms may undermine ART adherence, with overlapping vulnerabilities such as injection drug use and sexual/physical violence further exacerbating poor ART adherence. Women-centred, trauma-informed care approaches to detect menopause and treat menopausal symptoms are urgently needed. Such approaches should holistically address the intersecting barriers to adherence and link WLWH to peripheral health and social services, including trauma counseling and evidence-based harm reduction services.

Impact of inter-partner HIV disclosure patterns in Malawi's PMTCT program: A mixed-method study

Background

Evidence suggests that disclosure of HIV status between partners may influence prevention of maternal-to-child transmission of HIV (PMTCT) outcomes. We report partner disclosure in relation to maternal antiretroviral therapy (ART) uptake and adherence, and MTCT among postpartum HIV-infected Malawian women.

Methods

A cross-sectional mixed-method study was conducted as part of a nationally representative longitudinal cohort study. Between 2014–2016, all (34,637) mothers attending 54 under-5 clinics with their 4–26 week-old infants were approached, of which 98% (33,980) were screened for HIV; infants received HIV-1 DNA testing. HIV-exposure was confirmed in 3,566/33,980 (10.5%). Baseline data from mothers who were known to be HIV-infected at time of screening were included in the current analysis. Guardians (n = 17), newly diagnosed HIV-infected mothers (n = 256) and mothers or infants with undetermined HIV status (n = 30) were excluded. Data collected included socio-demographics, partner disclosure, maternal ART uptake, and adherence. Between 2016–2017, in-depth interviews and focus group discussions were conducted with adult mothers (n = 53) and their spouse/cohabiting partners (n = 19), adolescent mothers (n = 13), lost-to-follow up (LTFU) mothers (n = 22), community leaders (n = 23) and healthcare workers (n = 154).

Results

Of 3153 known HIV-infected mothers, 2882 (91.4%) reported having a spouse/cohabiting partner. Among 2882 couples, both partners, one partner, and neither partner disclosed to each other in 2090 (72.5%), 622 (21.6%), and 169 (5.9%), respectively. In multivariable models, neither partner disclosing was associated with no maternal ART (aOR 4.7; 95%CI 2.5–8.8), suboptimal treatment adherence (aOR 1.8; 95%CI 1.1–2.8) and MTCT (aOR 2.1; 95%CI 1.1–4.1). Women’s fear of blame by partners was central to decisions not to disclose within couples and when starting new relationships. LTFU mothers struggled to accept and disclose their status, hindering treatment initiation; some were unable to hide ART and feared involuntary disclosure.

Conclusion

Partner disclosure seems to play an important role in women’s decisions regarding ART initiation and adherence. Inter-partner non-disclosure was associated with no ART uptake, suboptimal treatment adherence and MTCT.

Assessing the Acceptability of a Peer Mentor Mother Intervention to Improve Retention in Care of Postpartum Women Living with HIV

Background: Many women living with HIV (WLWH) experience poor postpartum retention in HIV care. There are limited evidence-based interventions in the United States aimed at increasing retention of WLWH postpartum; however, evidence from low-resource settings suggest that women who receive peer mentoring experience higher retention and viral suppression postpartum.

Methods: We conducted 15 semistructured interviews with pregnant or postpartum women from an urban U.S. clinic to assess factors influencing maternal adherence to antiretroviral therapy (ART) and retention in HIV care. We then assessed the acceptability of a peer intervention in mitigating barriers to sustain adherence and retention in care postpartum. Interviews were audio taped, transcribed, and analyzed. Codes were developed and applied to all transcripts, and matrices were used to facilitate comparisons across different types of participants.

Results: Participants included low-income black and Hispanic women with a mean age of 31 years (range 22–42). Social support and concern for infants' well-being were strong facilitators for engaging in care. Psychosocial challenges, such as stigma and isolation, fear of disclosure, and depression, negatively influenced adherence to ART and engagement in care. Regardless of their level of adherence to ART, women felt that peer mentoring would be an acceptable intervention to reinforce skill-related ART adherence and sustain engagement in care after delivery.

Conclusion: A peer mentor mother program is a promising intervention that can improve the care continuum of pregnant and postpartum women in the United States. Messaging that maximizes maternal support and women's motivation to keep their infant healthy may leverage retention in care postpartum.

Examining engagement in care of women living with HIV in South India

HIV seropositive adherence-challenged women, who reported being on ART for at least four months were interviewed. Data on healthcare history, anti-retroviral therapy, clinic visits, doctor communication, disclosure and fear of stigma were collected. Better engagement in care was significantly more likely among older women, ≥ 10 years of education, higher income, HIV status disclosure to family, with higher community stigma fears and fewer healthcare access barriers. To promote retention, women may be encouraged to consider disclosing their HIV serostatus to supportive household members. A variety of possible interventions to overcome the prevalent barriers to care are provided.

Towards person-centred care for people living with HIV: what core outcomes matter, and how might we assess them? A cross-national multi-centre qualitative study with key stakeholders

OBJECTIVES

People living with HIV (PLWH) have multidimensional concerns requiring person-centred care. Routine use of patient-reported outcome measures (PROMs) improves outcomes. No brief PROM currently reflects the breadth of concerns for PLWH. This study sought to identify priority outcomes for PLWH, model current practice, explore views on introducing PROMs into routine care, and devise a model for person-centred care incorporating the PROM.

METHODS

A cross-national multi-centre study (London, Brighton and Dublin) was carried out. Semi-structured qualitative interviews with adult PLWH, HIV health care professionals and HIV commissioners (responsible for planning and commissioning services) were performed. Interviews were analysed using thematic and framework analysis.

RESULTS

PLWH (n = 28), professionals (n = 21) and commissioners (n = 8) described concerns related to living with HIV across six domains: physical (e.g. pain and gastrointestinal symptoms), cognitive (e.g. memory and sleep), psychological (e.g. anxiety and depression), social (e.g. isolation and intimacy), welfare (e.g. finances and fears regarding change of immigration status), and information (e.g. long-term outcomes) needs. Themes were highly inter-related, impacting across domains of need (e.g. physical and cognitive problems impacting on psychological and social wellbeing). Perceived benefits of using PROMs in routine HIV care included improved person-centredness, patient empowerment, fewer missed concerns, increased engagement with services, and informed planning of services. Potential challenges included heterogeneity of PLWH, literacy, and utility for those who struggle to engage with care.

CONCLUSIONS

This study presents a novel model of person-centred care incorporating an HIV-specific PROM. The model reflects priorities of key stakeholders. Explicit use of PROMs in routine HIV care could afford benefits for PLWH, clinical teams and commissioners.

'If nurses were in our shoes would they breastfeed their own babies?' A qualitative inquiry on challenges faced by breastfeeding mothers on the PMTCT programme in a rural community in Zimbabwe

BACKGROUND

The Prevention of Mother to Child Transmission (PMTCT) of HIV programme in Zimbabwe has had remarkable success despite the country's economic challenges. The aim of this study was to explore the challenges faced by breastfeeding mothers on the PMTCT programme.

METHOD

Narratives from 15 women (age range 19-35 years) were collected at two rural health facilities in Zimbabwe through in-depth interviews over a period of 6 months. Thematic analysis was used to describe breastfeeding mothers' experiences and challenges of being on the PMTCT programme.

RESULTS

The findings suggest that breastfeeding women on the PMTCT programme face challenges that include internal, external and institutional stigma and discrimination. Women reported a sense of powerlessness in decision making on following through with the PMTCT programme and were ambivalent regarding disclosure of their HIV status to their partners and significant others.

CONCLUSION

HIV and AIDS programmes should pay attention to women's readiness for interventions. There is need to understand women's life experiences to ensure informed and targeted programming for PMTCT.

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.

Understanding factors influencing linkage to HIV care in a rural setting, Mbeya, Tanzania: qualitative findings of a mixed methods study

BACKGROUND

In remote rural Tanzania, the rate of linkage into HIV care was estimated at 28% in 2014. This study explored facilitators and barriers to linkage to HIV care at individual/patient, health care provider, health system, and contextual levels to inform eventual design of interventions to improve linkage to HIV care.

METHODS

We conducted a descriptive qualitative study nested in a cohort study of 1012 newly diagnosed HIV-positive individuals in Mbeya region between August 2014 and July 2015. We conducted 8 focus group discussions and 10 in-depth interviews with recently diagnosed HIV-positive individuals and 20 individual interviews with healthcare providers. Transcripts were analyzed inductively using thematic content analysis. The emergent themes were then deductively fitted into the four level ecological model.

RESULTS

We identified multiple factors influencing linkage to care. HIV status disclosure, support from family/relatives and having symptoms of disease were reported to facilitate linkage at the individual level. Fear of stigma, lack of disclosure, denial and being asymptomatic, belief in witchcraft and spiritual beliefs were barriers identified at individual's level. At providers' level; support and good patient-staff relationship facilitated linkage, while negative attitudes and abusive language were reported barriers to successful linkage. Clear referral procedures and well-organized clinic procedures were system-level facilitators, whereas poorly organized clinic procedures and visit schedules, overcrowding, long waiting times and lack of resources were reported barriers. Distance and transport costs to HIV care centers were important contextual factors influencing linkage to care.

CONCLUSION

Linkage to HIV care is an important step towards proper management of HIV. We found that access and linkage to care are influenced positively and negatively at all levels, however, the individual-level and health system-level factors were most prominent in this setting. Interventions must address issues around stigma, denial and inadequate awareness of the value of early linkage to care, and improve the capacity of HIV treatment/care clinics to implement quality care, particularly in light of adopting the 'Test and Treat' model of HIV treatment and care recommended by the World Health Organization.

Healthcare worker experiences with Option B+ for prevention of mother-to-child HIV transmission in eSwatini: findings from a two-year follow-up study

BACKGROUND

Prevention of mother-to-child transmission (PMTCT) across sub-Saharan Africa has rapidly shifted towards Option B+, an approach in which all HIV+ pregnant and breastfeeding women initiate lifelong antiretroviral therapy (ART) independent of CD4+ count. Healthcare workers (HCW) are critical to the success of Option B+, yet little is known regarding HCW acceptability of Option B+, particularly over time.

METHODS

Ten health facilities in the Manzini and Lubombo regions of eSwatini transitioned from Option A to Option B+ between 2013 and 2014 as part of the Safe Generations study examining PMTCT retention. Fifty HCWs (5 per facility) completed questionnaires assessing feasibility and acceptability: (1) prior to transitioning to Option B+, (2) two months post transition, and (3) approximately 2 years post Option B+ transition. This analysis describes HCW perceptions and experiences two years after transitioning to Option B+.

RESULTS

Two years after transition, 80% of HCWs surveyed reported that Option B+ was easy for HCWs, noting that it was particularly easy to explain and coordinate. Immediate ART initiation also reduced delays by eliminating need for laboratory tests prior to ART initiation. Additionally, HCWs reported ease of patient follow-up (58%), documentation (56%), and counseling (58%) under Option B+. Findings also indicate that a majority of HCWs reported that their workloads increased under Option B+. Sixty-eight percent of HCWs at two years post-transition reported more work under Option B+, specifically noting increased involvement in adherence counseling, prescribing/monitoring medications, and appointment scheduling/tracking. Some HCWs attributed their higher workloads to increased client loads, now that all HIV-positive women were initiated on ART. New barriers to patient uptake, and issues related to retention, adherence, and follow-up were also noted as challenges face by HCW when implementing Option B+.

CONCLUSIONS

Overall, HCWs found Option B+ to be acceptable and feasible while providing critical insights into the practical issues of universal ART. Further strengthening of the healthcare system may be necessary to alleviate worker burden and to ensure effective monitoring of client retention and adherence. HCW perceptions and experiences with Option B+ should be considered more broadly as countries implement Option B+ and consider universal treatment for all HIV+ individuals.

Effects of antiretroviral therapy in HIV-positive adults on new HIV infections among young women: a systematic review protocol

BACKGROUND

The HIV/AIDS pandemic has struck regions, countries, and populations in different ways. With the introduction of antiretroviral drugs, people living with HIV (PLHIV) have a much better prognosis, even though there are still many new infections in young women. The role of widespread antiretroviral therapy (ART) on the incidence of HIV in young women is unknown.

METHODS

We will conduct a comprehensive search of MEDLINE (PubMed), Excerpta Medica database (EMBASE), Scopus, Google Scholar, Cochrane Central Register of Controlled Trials (CENTRAL), World Health Organization's (WHO's) library database, Latin American and Caribbean Health Sciences Literature (LILACS), conference abstracts, and gray literature sources to identify any relevant literature. We will include randomized and non-randomized clinical trials and cohort studies in which ART was offered to adults aged 18 and above reporting outcomes in females aged 15 to 24 years. The outcomes of interest are HIV incidence, ART initiation, adherence, retention, and viral load suppression. We will screen titles, abstracts, and the full texts of relevant articles in duplicate. Disagreements will be resolved by consensus. We will extract data on the risk of HIV infection in younger females after the use of ART in the adult population.

DISCUSSION

To our knowledge, this is the first systematic review to look at the impact of ART use among adults on HIV incidence in young women. The results of this review will be used in a modeling study to simulate the effects of using ART as an effective tool to prevent sexual transmission of HIV to young women. Our findings will inform the treatment-as-prevention (TasP) strategy to reduce new HIV infections among young women.

A systematic review of selected human rights programs to improve HIV-related outcomes from 2003 to 2015: what do we know?

Background

Repressive legal environments and widespread human rights violations act as structural impediments to efforts to engage key populations at risk of HIV infection in HIV prevention, care, and treatment efforts. The identification and scale-up of human rights programs and rights-based interventions that enable coverage of and retention in evidence-based HIV prevention and treatment approaches is crucial for halting the epidemic.

Methods

We conducted a systematic review of studies that assessed the effectiveness of human rights interventions on improving HIV-related outcomes between 1/1/2003–28/3/2015 per PRISMA guidelines. Studies of any design that sought to evaluate an intervention falling into one of the following UNAIDS’ key human rights program areas were included: HIV-related legal services; monitoring and reforming laws, policies, and regulations; legal literacy programs; sensitization of lawmakers and law enforcement agents; and training for health care providers on human rights and medical ethics related to HIV.

Results

Of 31,861 peer-reviewed articles and reports identified, 23 were included in our review representing 15 different populations across 11 countries. Most studies (83%) reported a positive influence of human rights interventions on HIV-related outcomes. The majority incorporated two or more principles of the human rights-based approach, typically non-discrimination and accountability, and sought to influence two or more elements of the right to health, namely availability and acceptability. Outcome measures varied considerably, making comparisons between studies difficult.

Conclusion

Our review revealed encouraging evidence of human rights interventions enabling a comprehensive HIV response, yet critical gaps remain. The development of a research framework with standardized indicators is needed to advance the field. Promising interventions should be implemented on a larger scale and rigorously evaluated. Funding for methodologically sound evaluations of human rights interventions should match the demand for human rights-based and structural approaches to protect those most vulnerable from HIV infection.

Low Birthweight, Retention in HIV Care, and Adherence to ART Among Postpartum Women Living with HIV in Ghana

Care for low birthweight (LBW) infants can contribute to psychological difficulties and stigma among mothers living with HIV, creating challenges for antiretroviral therapy (ART) adherence and retention in HIV care. We explored how caring for LBW infants affects maternal ART adherence and retention in care. We conducted 30 in-depth interviews with postpartum women living with HIV in Accra, Ghana: 15 with LBW infants and 15 with normal birthweight (NBW) infants. Compared to mothers with NBW infants, mothers with LBW infants described how caring for their newborns led to increased caregiver burden, prolonged hospital stays, and stigma-contributing to incomplete ART adherence and missed clinical appointments. For a few women, care for LBW infants created opportunities for re-engagement in HIV care and motivation to adhere to ART. Results suggest women living with HIV and LBW babies in Ghana face increased challenges that impact their adherence to care and ART.

What causes non-adherence among some individuals on long term antiretroviral therapy? Experiences of individuals with poor viral suppression in Uganda

Background

Antiretroviral therapy (ART) use by people living with HIV reduces HIV transmission, morbidity, mortality, and improves quality of life. Good ART adherence is required to achieve these benefits. We investigated how the environmental, social, economic and behavioural experiences of people living with HIV with poor viral suppression could explain their non-adherence to long term ART.

Methods

This qualitative cross-sectional study was conducted in Uganda between September 2015 and April 2016. Thirty individuals on ART for 5 years or more (10 on first line and 20 on second line), with poor viral suppression, were randomly selected from a cohort of people living with HIV on ART. In-depth interviews about ART; awareness, adherence counselling, obstacles to daily adherence and regimen switches were conducted. Emerging themes from the interviews transcripts and field notes were identified and thematic content analysis done. Participants’ consent, compensation, confidentiality and study ethical approvals were ensured.

Results

We found that poor adherence to long term ART was due to: travel for work or social activities, stigma, receiving little or no continuous ART adherence education, alcohol consumption and use of alternative ‘HIV cure’ medicines. Other reasons included; ART side effects, treatment fatigue, belief that long-term ART or God can ‘cure HIV’, and food security.

Conclusions

Achieving optimal ART benefits requires continuous provision of ART adherence education to individuals on long term ART. This helps them overcome the challenges related to living with HIV: worries of food insecurity, alcohol misuse, economic hardship, and beliefs in HIV cures and use of unproven alternative HIV treatments. People living with HIV who travel require adherence support and larger quantities of ART refills to cover their time away.

Being HIV positive and staying on antiretroviral therapy in Africa: A qualitative systematic review and theoretical model

BACKGROUND

Adherence to antiretroviral therapy (ART) and long-term uninterrupted engagement in HIV care is difficult for HIV-positive people, and randomized trials of specific techniques to promote adherence often show small or negligible effects. Understanding what influences decision-making in HIV-positive people in Africa may help researchers and policy makers in the development of broader, more effective interventions and policies.

METHODS

We used thematic synthesis and a grounded theory approach to generate a detailed narrative and theoretical model reflecting life with HIV in Africa, and how this influences ART adherence and engagement decisions. We included qualitative primary studies that explored perspectives, perceptions and experiences of HIV-positive people, caregivers and healthcare service providers. We searched databases from 1 January 2013 to 9 December 2016, screened all studies, and selected those for inclusion using purposeful sampling methods. Included studies were coded with Atlas.ti, and we assessed methodological quality across five domains.

RESULTS

We included 59 studies from Africa in the synthesis. Nine themes emerged which we grouped under three main headings. First, people who are HIV-positive live in a complicated world where they must navigate the challenges presented by poverty, competing priorities, unpredictable life events, social identity, gender norms, stigma, and medical pluralism-these influences can make initiating and maintaining ART difficult. Second, the health system is generally seen as punishing and uninviting and this can drive HIV-positive people out of care. Third, long-term engagement and adherence requires adaptation and incorporation of ART into daily life, a process which is facilitated by: inherent self-efficacy, social responsibilities, previous HIV-related illnesses and emotional, practical or financial support. These factors together can lead to a "tipping point", a point in time when patients choose to either engage or disengage from care. HIV-positive people may cycle in and out of these care states in response to fluctuations in influences over time.

CONCLUSION

This analysis provides a practical theory, arising from thematic synthesis of research, to help understand the dynamics of adherence to ART and engagement in HIV care. This can contribute to the design of service delivery approaches, and informed thinking and action on the part of policy makers, providers, and society: to understand what it is to be HIV-positive in Africa and how attitudes and the health service need to shift to help those with HIV lead 'normal' lives.

Unpacking Loss to Follow-Up Among HIV-Infected Women Initiated on Option B+ In Northern Tanzania: A Retrospective Chart Review

Background:

In 2014, Tanzania adopted the Option B+ policy for the prevention of mother-to-child transmission of HIV (PMTCT), which stipulates lifelong antiretroviral therapy (ART) for HIV-infected pregnant, postpartum and breastfeeding women, irrespective of CD4 count or WHO clinical staging. Loss to follow-up (LTFU) during pregnancy and the postpartum period may undermine the effectiveness of Option B+. Factors associated with no follow-up (NFU) care, may differ from those associated with LTFU at later time points. This study aimed to identify factors associated with NFU and LTFU among women who initiate ART under Option B+ in Moshi, Tanzania.

Methods:

We conducted a retrospective chart review of patients initiating ART on Option B+ between February 2014 and December 2015 in Moshi Municipality, Tanzania. Multivariable log-binomial regression was used to analyse factors associated with NFU. Kaplan-Meier survival functions were used to estimate time to LTFU. Multivariable Cox proportion hazards regression models were used to evaluate variables associated with time to LTFU.

Results:

Among 468 women initiating ART under the option B+ programme, 109 (23.3%) had NFU after the initial appointment. Factors associated with increased risk of NFU were: age < 25 years (adjusted hazard ratio [aRR] 1.7; 95% CI, 1.2 to 2.3), initiating ART at a hospital compared to a lower level health facilities (aRR 2.9; 95% CI, 2.1 to 3.9), and having no treatment supporter (aRR 1.5; 95% CI, 1.1 to 2.1). LTFU was higher in women aged < 25 years (aHR 1.4; 95% CI, 1.1 to 1.9), and in women with no treatment supporter (aHR 1.8; 95% CI, 1.4 to 2.3). In women who returned to the clinic after ART initiation, no factor was significantly associated with LTFU.

Conclusion:

The factors associated with NFU (being young, not having a treatment supporter, and being diagnosed at hospitals) reflect a vulnerable and potentially highly mobile population. Additional interventions are needed to support and retain this group at ART initiation on Option B+.

Cumulative Live Birth Rates in Low Prognosis Patients According to the POSEIDON Criteria: An Analysis of 26,697 Cycles of in vitro Fertilization/Intracytoplasmic Sperm Injection

Objective: The POSEIDON criteria are used to stratify patients with low prognosis after assisted reproductive technology (ART) treatment. Since its introduction, there has been no large study about the prognosis of the POSEIDON population. We used the POSEIDON criteria in Chinese women who underwent repeated ART treatment and analyzed the association between POSEIDON criteria and the cumulative live-birth rate (CLBR). Methods: This was a retrospective cohort study of 62,749 women (97,388 cycles) who underwent ART treatment at the Reproductive and Genetic Hospital of CITIC-XIANGYA between January 2014 and June 2017. Among them, 19,781 (31.52%) women fulfilled the POSEIDON criteria, including 26,697 cycles. The optimal and conservative CLBRs within a complete IVF/ICSI treatment cycle were calculated, as well as the CLBRs following repeated ovarian stimulation cycles. Results: In POSEIDON groups 1, 2, 3, and 4, the optimal and conservative CLBRs of three complete consecutive in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) cycles were 83.87 and 66.06%, 53.67 and 37.72%, 44.24 and 27.98%, and 14.20 and 9.68%, respectively. The POSEIDON stratification [group 2: odds ratio (OR) = 2.319, 95% confidence interval (CI): 2.131-2.525, P < 0.001; group 3: OR = 1.356, 95% CI: 1.005-1.828, P = 0.046; group 4: OR = 3.525, 95% CI: 2.774-4.479, P < 0.001; all vs. group 1] and ovarian stimulation protocol [gonadotropin-releasing hormone (GnRH) antagonist protocol: OR = 1.856, 95% CI: 1.640-2.100, P < 0.001; other protocols: OR = 1.651, 95% CI: 1.155-2.361, P = 0.006; both vs. long GnRH agonist protocol] were associated with live birth in the first stimulation cycle. For the second stimulation cycle, the POSEIDON stratification (except POSEIDON group 3) and ovarian stimulation protocol were associated with live birth. A change in ovarian stimulation protocol was not associated with an improvement in the live birth rate. Conclusions: More than 30% of women who undergo IVF/ICSI treatment may be classified as low prognosis. Different reproductive outcomes were observed among the four POSEIDON groups. The most optimal outcomes after three successive cycles of IVF/ICSI treatment were observed in groups 1, 2, and 3.

Barriers and facilitators to the uptake of Test and Treat in Mozambique: A qualitative study on patient and provider perceptions

Background

In mid-2016, Mozambique began phased implementation of the ‘Test-and-Treat’ policy, which enrolls HIV positive clients into antiretroviral treatment (ART) immediately regardless of CD4 cell count or disease stage. Novel insights into barriers and facilitators to ART initiation among healthy clients are needed to improve implementation of Test and Treat.

Methods and findings

A cross-sectional qualitative study was conducted across 10 health facilities in Mozambique. In-depth interviews (IDIs) were conducted with HIV-positive clients (60 who initiated/20 who did not initiate ART within Test and Treat) and 9 focus group discussion (FGDs) were conducted with health care workers (HCWs; n = 53). Data were analyzed using deductive and inductive analysis strategies. Barriers to ART initiation included: (1) feeling ‘healthy’; (2) not prepared to start ART for life; (3) concerns about ART side effects; (4) fear of HIV disclosure and discrimination; (5) poor interactions with HCWs; (6) limited privacy at health facilities; and (7) perceptions of long wait times. Facilitators included the motivation to stay healthy and to take care of dependents, as well as new models of ART services such as adaptation of counseling to clients’ specific needs, efficient patient flow, and integrated HIV/primary care services.

Conclusions

ART initiation may be difficult for healthy clients in the context of Test-and-Treat. Specific strategies to engage this population are needed. Strategies could include targeted support for clients, community sensitization on the benefits of early ART initiation, client-centered approaches to patient care, and improved efficiency through multi-month scripting and increased workforce.

Effect of a multicomponent behavioural PMTCT cluster randomised controlled trial on HIV stigma reduction among perinatal HIV positive women in Mpumalanga province, South Africa

Background: We evaluate the impact a multicomponent, behavioural, prevention of mother to child transmission (PMTCT), cluster randomised controlled trial on HIV stigma reduction among perinatal HIV infected women in rural South Africa. Methods: In a cluster randomised controlled trial, twelve community health centres (CHCs) in Mpumalanga Province, South Africa, were randomised; pregnant women living with HIV enrolled received either: A Standard Care (SC) condition plus time-equivalent attention-control on disease prevention (SC; 6 CHCs; n =357), or an Enhanced Intervention (EI) condition of SC PMTCT plus the ‘Protect Your Family’ intervention (EI; 6 CHCs; n =342). HIV-infected pregnant women in the SC attended four antenatal and two postnatal video sessions; those in the EI, four antenatal and two postnatal group PMTCT sessions, including stigma reduction, led by trained lay health workers. Maternal PMTCT, HIV knowledge and HIV related stigma were assessed. The impact of the EI was ascertained on stigma reduction (baseline, 12 months postnatally). A series of logistic regression and latent growth curve models were developed to test the impact of the intervention. Results: In all, 699 women living with HIV were recruited during pregnancy (8–24 weeks), and assessments were completed prenatally at baseline and at 12 months (59.5%) postnatally. Baseline scores of overall HIV related stigma and the four scale factors (personalised stigma, disclosure concerns, negative self-image, and concern public attitudes) decreased at follow-up in the intervention group, while baseline scores of overall stigma and three scale factors (personalised stigma, negative self-image, and concern public attitudes) increased at follow-up in the control group. Using longitudinal analyses, Model 1, which included time-invariant predictors of stigma assessed over the two time periods of baseline and 12 months, increases in stigma from baseline to 12 months were associated with being unemployed, having been diagnosed with HIV before the current pregnancy, and alcohol use. In Model 2, which included time-varying predictors, lower stigma scores were associated with participation in the intervention, greater male partner involvement, and consistent condom use. Conclusion: The enhanced PMTCT intervention, including stigma reduction, administered by trained lay health workers had a significant effect on the reduction of HIV related stigma.

Implementing the package of CDC and WHO recommended linkage services: Methods, outcomes, and costs of the Bukoba Tanzania Combination Prevention Evaluation peer-delivered, linkage case management program, 2014-2017

Although several studies have evaluated one or more linkage services to improve early enrollment in HIV care in Tanzania, none have evaluated the package of linkage services recommended by the Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO). We describe the uptake of each component of the CDC/WHO recommended package of linkage services, and early enrollment in HIV care and antiretroviral therapy (ART) initiation among persons with HIV who participated in a peer-delivered, linkage case management (LCM) program implemented in Bukoba, Tanzania, October 2014 –May 2017. Of 4206 participants (88% newly HIV diagnosed), most received recommended services including counseling on the importance of early enrollment in care and ART (100%); escort by foot or car to an HIV care and treatment clinic (CTC) (83%); treatment navigation at a CTC (94%); telephone support and appointment reminders (77% among clients with cellphones); and counseling on HIV-status disclosure and partner/family testing (77%), and on barriers to care (69%). During three periods with different ART-eligibility thresholds [CD4<350 (Oct 2014 –Dec 2015, n = 2233), CD4≤500 (Jan 2016 –Sept 2016, n = 1221), and Test & Start (Oct 2016 –May 2017, n = 752)], 90%, 96%, and 97% of clients enrolled in HIV care, and 47%, 67%, and 86% of clients initiated ART, respectively, within three months of diagnosis. Of 463 LCM clients who participated in the last three months of the rollout of Test & Start, 91% initiated ART. Estimated per-client cost was $44 United States dollars (USD) for delivering LCM services in communities and facilities overall, and $18 USD for a facility-only model with task shifting. Well accepted by persons with HIV, peer-delivered LCM services recommended by CDC and WHO can achieve near universal early ART initiation in the Test & Start era at modest cost and should be considered for implementation in facilities and communities experiencing <90% early enrollment in ART care.

Uptake of antiretroviral therapy in HIV-positive women ever enrolled into 'prevention of mother to child transmission' programme, Mandalay, Myanmar-a cohort study

Background

Early initiation and longer duration of anti-retroviral therapy either as prophylaxis (pARV) or lifelong treatment (ART) in HIV-positive pregnant women prior to delivery has a huge impact in reducing mother to child transmission (MTCT) of HIV, maternal morbidity, mortality and increasing retention in care. In this study, we aimed to determine the following in a ‘prevention of mother-to-child transmission’ (PMTCT) programme in Central Women Hospital, Mandalay, Myanmar: i) uptake of ART and factors associated with the uptake ii) duration of ART/ pARV received by HIV-positive pregnant women prior to delivery, iii) factors associated with ART/ pARV initiation after delivery and iv) factors associated with shorter duration of ART/ pARV (≤ 8 weeks prior to delivery).

Method

This was a retrospective cohort study using routinely collected data from PMTCT programme. We used multivariable Cox proportional Hazard model or log binomial models to assess the association between socio-demographic and clinical factors with a) uptake of ART/pARV, b) initiation of ART/pARV after delivery, c) shorter (≤8 weeks) duration of ART/PARV prior to delivery.

Results

Of the 670 ART naïve HIV-positive women enrolled to PMTCT programme between March 2011 and December 2016, 588 (88%) were initiated on ART/pARV. In adjusted analysis, only pregnancy stage at enrolment was significantly associated with initiation of ART/pARV. Of 585 who had delivered babies on or before the censor date, 522 (89%) were on ART/pARV. Women who lived outside Mandalay were more likely to be initiated on ART after delivery (i.e., delayed ART initiation in those on ART). Among women who were initiated on ART/pARV before delivery (n = 468), only 59% got ART/pARV for > 8 weeks before delivery. Women whose spouses’ HIV status was not recorded had 40% higher risk of short duration of ART/pARV.

Conclusions

This study shows high uptake of ART/pARV among those enrolled into the PMTCT programme. However, about one in eight pregnant women did not receive ART before delivery. Among those initiated on ART/pARV before delivery, nearly half of them received ART/pARV for less than 8 weeks prior to delivery. These aspects need to be improved in order to eliminate mother-to-child transmission of HIV.

Patterns and Predictors of HIV-Status Disclosure Among Pregnant Women in South Africa: Dimensions of Disclosure and Influence of Social and Economic Circumstances

HIV-status disclosure may improve psychosocial health and adherence to antiretroviral therapy (ART), but existing insights suffer from methodological limitations. We explored disclosure over time during pregnancy and postpartum among 1347 HIV-positive women in Cape Town. Among 995 women diagnosed HIV-positive before the pregnancy and entering antenatal care (median age 30 years), 95% had disclosed to ≥ 1 individual. In Mokken scale analysis, we observed two separate dimensions of disclosure: disclosure to a male partner, and disclosure to family/community members. Among 352 women diagnosed during the pregnancy and initiating ART (median age 27 years), 61% disclosed to a male partner and 71% to a family/community member by 12 months after diagnosis. Relationship status modified the impact of pregnancy intentions and poverty on disclosure to a male partner. These unique data provide important insights into dimensions of disclosure during pregnancy and postpartum, and suggest that women's social and economic circumstances are central determinants of disclosure.

Probable antenatal depression at antiretroviral initiation and postpartum viral suppression and engagement in care

OBJECTIVE

To estimate the association of probable antenatal depression with postpartum HIV care engagement among pregnant women in Malawi.

DESIGN

We conducted a prospective cohort study of 299 women who were initiating antiretroviral therapy (ART) through Option B+ at a government antenatal clinic in Malawi.

METHODS

Probable antenatal depression was assessed on the day of ART initiation with the validated Chichewa version of the Edinburgh Postnatal Depression Scale (EPDS). We estimated crude and adjusted risk differences (RD, aRD) of visit attendance and prevalence differences (PD, aPD) of viral suppression through 12 months post-ART initiation comparing women with versus without probable antenatal depression.

RESULTS

One in 10 women had probable antenatal depression. Most women were engaged in care through 12 months post-ART initiation: 85% attended all scheduled ART visits, and 81% were in care and virally suppressed. Women with and without probable antenatal depression had a comparable probability of attending all scheduled visits (RD: -0.02; 95% CI -0.16 to 0.12; aRD: -0.04; 95% CI -0.18 to 0.10), and of viral suppression (PD: -0.02; 95% CI -0.17 to 0.13; aPD: -0.01; 95% CI -0.17 to 0.15) in crude and adjusted analyses.

CONCLUSION

Probable antenatal depression was not associated with engagement in HIV care through 12 months post-ART initiation. In a population with high HIV care engagement, antenatal depression may not impair HIV-related outcomes.

Processes and dynamics of linkage to care from mobile/outreach and facility-based HIV testing models in hard-to-reach settings in rural Tanzania. Qualitative findings of a mixed methods study

BACKGROUND

Like other countries, Tanzania instituted mobile and outreach testing approaches to address low HIV testing rates at health facilities and enhance linkage to care. Available evidence from hard-to-reach rural settings of Mbeya region, Tanzania suggests that clients testing HIV+ at facility-based sites are more likely to link to care, and to link sooner, than those testing at mobile sites. This paper (1) describes the populations accessing HIV testing at mobile/outreach and facility-based testing sites, and (2) compares processes and dynamics from testing to linkage to care between these two testing models from the same study context.

METHODS

An explanatory sequential mixed-method study (a) reviewed records of all clients (n = 11,773) testing at 8 mobile and 8 facility-based testing sites over 6 months; (b), reviewed guidelines; (c) observed HIV testing sites (n = 10) and Care and Treatment Centers (CTCs) (n = 8); (d) applied questionnaires at 0, 3 and 6 months to a cohort of 1012 HIV newly-diagnosed clients from the 16 sites; and (e) conducted focus group discussions (n = 8) and in-depth qualitative interviews with cohort members (n = 10) and health care providers (n = 20).

RESULTS

More clients tested at mobile/outreach than facility-based sites (56% vs 44% of 11,733, p < 0.001). Mobile site clients were more likely to be younger and male (p < 0.001). More clients testing at facility sites were HIV positive (21.5% vs. 7.9% of 11,733, p < 0.001). All sites in both testing models adhered to national HIV testing and care guidelines. Staff at mobile sites showed more proactive efforts to support linkage to care, and clients report favouring the confidentiality of mobile sites to avoid stigma. Clients who tested at mobile/outreach sites faced longer delays and waiting times at treatment sites (CTCs).

CONCLUSIONS

Rural mobile/outreach HIV testing sites reach more people than facility based sites but they reach a different clientèle which is less likely to be HIV +ve and appears to be less "linkage-ready". Despite more proactive care and confidentiality at mobile sites, linkage to care is worse than for clients who tested at facility-based sites. Our findings highlight a combination of (a) patient-level factors, including stigma; and (b) well-established procedures and routines for each step between testing and initiation of treatment in facility-based sites. Long waiting times at treatment sites are a further barrier that must be addressed.

Perceived Barriers to Antepartum HIV Medication Adherence in HIV Infected Pregnant Women

Introduction

Although rare, perinatal HIV transmission still occurs in the United States and most transmissions are preventable. We aim to identify patient barriers to antiretroviral therapy (ART) adherence during pregnancy and assess patient understanding of perinatal transmission.

Methods

This cross-sectional survey recruited HIV positive postpartum women at a large safety net hospital in Atlanta, Georgia, between January 2016 and February 2018. Survey questions included demographic characteristics, HIV history, knowledge of perinatal transmission, and ART adherence. Perinatal and HIV outcomes were assessed using chart abstraction.

Results

Of the 70 HIV infected postpartum women delivered at a large safety net hospital in Atlanta, GA, 45 women were eligible and consented to participate. Participating women were aged 18 to 40 years with an average age of 29 years old, 93% of participants were African-American, and 68% had ≥3 pregnancies. The majority of participants (75%) reported daily ART adherence. "Forgetting" was the most frequent reason for missing pills (57%). Thirteen women had a detectable viral load at the time of delivery and nine of those women had a viral load greater than 1000 copies/mL. Approximately 85% of women who correctly stated ART medications decrease perinatal transmission risk reported daily adherence compared with 50% of women without that knowledge (OR 5.6, 95% CI 1.17, 26.7). Almost half of women (40%) either did not know or believed a vaginal delivery, regardless of viral load, would increase their risk of perinatal transmission.

Conclusion

Overall, women who were diagnosed with HIV during the current pregnancy, those with planned pregnancies, and those who were on medications prior to pregnancy were more likely to report daily ART adherence. Detectable viral load at delivery is the greatest risk factor for perinatal transmission; therefore strategies to increase ART adherence are needed.

Strategies to improve adherence to antiretroviral therapy and retention in care for people living with HIV in high-income countries: a protocol for an overview of systematic reviews

INTRODUCTION

While access to antiretroviral therapy (ART) for people living with HIV has expanded in recent years, additional efforts are required to support adherence to medication and retention in care. Interventions should be applicable in real-world settings and amenable to widespread use. The objectives of this overview are to identify effective pragmatic interventions that increase adherence to ART and retention in care for people living with HIV at high risk for suboptimal adherence and retention in high-income countries.

METHODS AND ANALYSIS

We will conduct an overview of systematic reviews of studies on interventions which target improved adherence to medication and retention in care among high-risk people living with HIV in high-income countries (men who have sex with men, African, Caribbean and black people, sex workers, people who inject drugs, indigenous people and other socially marginalised groups). We will search the following databases: PubMed, EMBASE (Exerpta Medica Database), CINAHL (Cumulative Index to Nursing and Allied Health Literature), PsycINFO, Web of Science and the Cochrane Library. We will conduct screening, data extraction and assessment of methodological quality of the systematic reviews. Analysis will be narrative. Our findings will be interpreted in light of the certainty of the evidence, level of pragmatism, setting and population of interest.

ETHICS AND DISSEMINATION

Only published secondary data will be used in this study, and therefore ethics approval is not required. Our findings will be disseminated as peer-reviewed manuscripts, conference abstracts and through community activities. The findings from this overview will inform a mixed-methods study among people living with HIV and health workers in Ontario, Canada.

Associations between health systems capacity and mother-to-child HIV prevention program outcomes in Zambia

Introduction

Zambia has made substantial investments in health systems capacity, yet it remains unclear whether improved service quality improves outcomes. We investigated the association between health system capacity and use of prevention of mother-to-child HIV transmission (PMTCT) services in Zambia.

Materials and methods

We analyzed data from two studies conducted in rural and semi-urban Lusaka Province in 2014–2015. Health system capacity, our primary exposure, was measured with a validated balanced scorecard approach. Based on WHO building blocks for health systems strengthening, we derived overall and domain-specific facility scores (range: 0–100), with higher scores indicating greater capacity. Our outcome, community-level maternal antiretroviral drug use at 12 months postpartum, was measured via self-report in a large cohort study evaluating PMTCT program impact. Associations between health systems capacity and our outcome were analyzed via linear regression.

Results

Among 29 facilities, median overall facility score was 72 (IQR:67–74). Median domain scores were: patient satisfaction 75 (IQR 71–78); human resources 85 (IQR:63–87); finance 50 (IQR:50–67); governance 82 (IQR:74–91); service capacity 77 (IQR:68–79); service provision 60 (IQR:52–76). Our programmatic outcome was measured from 804 HIV-infected mothers. Median community-level antiretroviral use at 12 months was 81% (IQR:69–89%). Patient satisfaction was the only domain score significantly associated with 12-month maternal antiretroviral use (β:0.22; p = 0.02). When we excluded the human resources and finance domains, we found a positive association between composite 4-domain facility score and 12-month maternal antiretroviral use in peri-urban but not rural facilities.

Conclusions

In these Zambian health facilities, patient satisfaction was positively associated with maternal antiretroviral 12 months postpartum. The association between overall health system capacity and maternal antiretroviral drug use was stronger in peri-urban versus rural facilities. Additional work is needed to guide strategic investments for improved outcomes in HIV and broader maternal-child health region-wide.

Adolescent pregnancy at antiretroviral therapy (ART) initiation: a critical barrier to retention on ART

INTRODUCTION

Adolescence and pregnancy are potential risk factors for loss to follow-up (LTFU) while on antiretroviral therapy (ART). We compared adolescent and adult LTFU after ART initiation to quantify the impact of age, pregnancy, and site-level factors on LTFU.

METHODS

We used routine clinical data for patients initiating ART as young adolescents (YA; 10 to 14 years), older adolescents (OA; 15 to 19 years) and adults (≥20 years) from 2000 to 2014 at 52 health facilities affiliated with the International epidemiology Databases to Evaluate AIDS (IeDEA) East Africa collaboration. We estimated cumulative incidence (95% confidence interval, CI) of LTFU (no clinic visit for ≥6 months after ART initiation) and identified patient and site-level correlates of LTFU, using multivariable Cox proportional hazards models for all patients as well as individual age groups.

RESULTS

A total of 138,387 patients initiated ART, including 2496 YA, 2955 OA and 132,936 adults. Of these, 55%, 78% and 66%, respectively, were female and 0.7% of YA, 22.3% of OA and 8.3% of adults were pregnant at ART initiation. Cumulative incidence of LTFU at five years was 26.6% (24.6 to 28.6) among YA, 44.1% (41.8 to 46.3) among OA and 29.3% (29.1 to 29.6) among adults. Overall, compared to adults, the adjusted hazard ratio, aHR, (95% CI) of LTFU for OA was 1.54 (1.41 to 1.68) and 0.77 (0.69 to 0.86) for YA. Compared to males, pregnant females had higher hazard of LTFU, aHR 1.20 (1.14 to 1.27), and nonpregnant women had lower hazard aHR 0.90 (0.88 to 0.93). LTFU hazard among the OA was primarily driven by both pregnant and nonpregnant females, aHR 2.42 (1.98 to 2.95) and 1.51 (1.27 to 1.80), respectively, compared to men. The LTFU hazard ratio varied by IeDEA program. Site-level factors associated with overall lower LTFU hazard included receiving care in tertiary versus primary-care clinics aHR 0.61 (0.56 to 0.67), integrated adult and adolescent services and food ration provision aHR 0.93 (0.89 to 0.97) versus nonintegrated clinics with food ration provision, having patient support groups aHR 0.77 (0.66 to 0.90) and group adherence counselling aHR 0.61 (0.57 to 0.67).

CONCLUSIONS

Older adolescents experienced higher risk of LTFU compared to YA and adults. Interventions to prevent LTFU among older adolescents are critically needed, particularly for female and/or pregnant adolescents.

A Bayesian Analysis of Prenatal Maternal Factors Predicting Nonadherence to Infant HIV Medication in South Africa

While efforts to prevent mother-to-child transmission of HIV been successful in some districts in South Africa, rates remain unacceptably high in others. This study utilized Bayesian logistic regression to examine maternal-level predictors of adherence to infant nevirapine prophylaxis, including intimate partner violence, maternal adherence, HIV serostatus disclosure reaction, recency of HIV diagnosis, and depression. Women (N = 303) were assessed during pregnancy and 6 weeks postpartum. Maternal adherence to antiretroviral therapy during pregnancy predicted an 80% reduction in the odds of infant nonadherence [OR 0.20, 95% posterior credible interval (.11, .38)], and maternal prenatal depression predicted an increase [OR 1.04, 95% PCI (1.01, 1.08)]. Results suggest that in rural South Africa, failure to provide medication to infants may arise from shared risk factors with maternal nonadherence. Intervening to increase maternal adherence and reduce depression may improve adherence to infant prophylaxis and ultimately reduce vertical transmission rates.

Why do people living with HIV not initiate treatment? A systematic review of qualitative evidence from low- and middle-income countries

BACKGROUND

Many people living with HIV (PLWH) who are eligible for antiretroviral therapy (ART) do not initiate treatment, leading to excess morbidity, mortality, and viral transmission. As countries move to treat all PLWH at diagnosis, it is critical to understand reasons for non-initiation.

METHODS

We conducted a systematic review of the qualitative literature on reasons for ART non-initiation in low- and middle-income countries. We screened 1376 titles, 680 abstracts, and 154 full-text reports of English-language qualitative studies published January 2000-April 2017; 20 met criteria for inclusion. Our analysis involved three steps. First, we used a "thematic synthesis" approach, identifying supply-side (facility) and demand-side (patient) factors commonly cited across different studies and organizing these factors into themes. Second, we conducted a theoretical mapping exercise, developing an explanatory model for patients' decision-making process to start (or not to start) ART, based on inductive analysis of evidence reviewed. Third, we used this explanatory model to identify opportunities to intervene to increase ART uptake.

RESULTS

Demand-side factors implicated in decisions not to start ART included feeling healthy, low social support, gender norms, HIV stigma, and difficulties translating intentions into actions. Supply-side factors included high care-seeking costs, concerns about confidentiality, low-quality health services, recommended lifestyle changes, and incomplete knowledge of treatment benefits. Developing an explanatory model, which we labeled the Transdisciplinary Model of Health Decision-Making, we posited that contextual factors determine the costs and benefits of ART; patients perceive this context (through cognitive and emotional appraisals) and form an intention whether or not to start; and these intentions may (or may not) be translated into actions. Interventions can target each of these three stages.

CONCLUSIONS

Reasons for not starting ART included consistent themes across studies. Future interventions could: (1) provide information on the large health and prevention benefits of ART and the low side effects of current regimens; (2) reduce stigma at the patient and community levels and increase confidentiality where stigma persists; (3) remove lifestyle requirements and support patients in integrating ART into their lives; and (4) alleviate economic burdens of ART. Interventions addressing reasons for non-initiation will be critical to the success of HIV "treat all" strategies.

Nurturing the Continuum of HIV Testing, Treatment and Prevention Matrix Cascade in Reducing HIV Transmission

Background

Despite the shift in antiretroviral therapy (ARVs) eligibility cascade from CD4 ≤ 200 to CD4 ≤ 350 to CD4 ≤ 500 mm³, HIV related morbidity and mortality continue to escalate annually, as do HIV infections. The new paradigm of treatment for all HIV positives individual irrespective of CD4 count may significantly reduce HIV and related illnesses. The author assumes that all HIV infected partners should be eligible for HIV treatment and care, irrespective of CD4 count. A second assumption is that high risk HIV negative partners have free access to continuum of HIV pre-exposure prophylaxis (PrEP), post exposure prophylaxis (PEP) and other prevention packages.

Methods

A literature review search was used to extract evidence-based ARVs-HIV treatment and prevention interventions among HIV positives and high risk partners respectively. Only articles published in English and indexed in journal nuclei were used for the study. The information was used to nurture understanding of HIV treatment and prevention approaches as well as HIV incidence multiplier effect among HIV serodiscordant partners. The imputed HIV incident reference was assumed at 1.2 per 100 person-years (2). This was based on the imputation that retention in care, adherence and other predetermined factors are functions of an effective health care delivery system.

Result

The model showed a reduced HIV transmission from 1.2 per 100 person-years to 1.032 per 100 person-years in 6 months. The average threshold period of HIV suppressed partners on ARVs to an undetectable level. The combined multiplier protective-effect probability of transmitting HIV from HIV positive partners on ARVs-suppressed viremic load to HIV negative partners on PrEP/PEP-prevention was detected at 86%

Conclusion

The model showed a significant reduction in HIV incidence. Placing serodiscordant sexual partners in HIV treatment and prevention plays a significant role in reducing and controlling HIV infection. Therefore, the policy of enrolling all HIV positives irrespective of CD4 count on ARVs and high risk partners on prevention if adopted and sustained may underpin reduction and control of HIV genotype and HIV related morbidity, mortality and opportunistic infections.
