Adolescent HIV disclosure in Zambia: barriers, facilitators and outcomes.

As adolescents living with HIV gain autonomy over their self‐care and begin to engage in sexual relationships, their experiences of being informed about their HIV status and of telling others about their HIV status may affect their ability to cope with having the disease.

Improving PMTCT uptake and retention services through novel approaches in peer-based family-supported care in the clinic and community: a 3-arm cluster randomized trial (PURE Malawi).

Abstract:In July 2011, Malawi introduced an ambitious public health program known as “Option B+,” which provides all HIV-infected pregnant and breastfeeding women with lifelong combination antiretroviral therapy, regardless of clinical stage or CD4 count. Option B+ is expected to have benefits for HIV-infected women, their HIV-exposed infants, and their HIV-uninfected male sex partners. However, these benefits hinge on early uptake of prevention of mother-to-child transmission, good adherence, and long-term retention in care. The Prevention of mother-to-child transmission Uptake and REtention (PURE) study is a 3-arm cluster randomized controlled trial to evaluate whether clinic- or community-based peer support will improve care-seeking and retention in care by HIV-infected pregnant and breastfeeding women, their HIV-exposed infants, and their male sex partners, and ultimately improve health outcomes in all 3 populations. We describe the PURE Malawi Consortium, the initial work conducted to inform the trial and interventions, the trial design, and the analysis plan. We then discuss concerns and expected contributions to Malawi and the region.

The Lablite project: A cross-sectional mapping survey of decentralized HIV service provision in Malawi, Uganda and Zimbabwe

BackgroundIn sub-Saharan Africa antiretroviral therapy (ART) is being decentralized from tertiary/secondary care facilities to primary care. The Lablite project supports effective decentralization in 3 countries. It began with a cross-sectional survey to describe HIV and ART services.Methods81 purposively sampled health facilities in Malawi, Uganda and Zimbabwe were surveyed.ResultsThe lowest level primary health centres comprised 16/20, 21/39 and 16/22 facilities included in Malawi, Uganda and Zimbabwe respectively. In Malawi and Uganda most primary health facilities had at least 1 medical assistant/clinical officer, with average 2.5 and 4 nurses/midwives for median catchment populations of 29,275 and 9,000 respectively. Primary health facilities in Zimbabwe were run by nurses/midwives, with average 6 for a median catchment population of 8,616. All primary health facilities provided HIV testing and counselling, 50/53 (94%) cotrimoxazole preventive therapy (CPT), 52/53 (98%) prevention of mother-to-child transmission of HIV (PMTCT) and 30/53 (57%) ART management (1/30 post ART-initiation follow-up only). All secondary and tertiary-level facilities provided HIV and ART services. In total, 58/81 had ART provision. Stock-outs during the 3 months prior to survey occurred across facility levels for HIV test-kits in 55%, 26% and 9% facilities in Malawi, Uganda and Zimbabwe respectively; for CPT in 58%, 32% and 9% and for PMTCT drugs in 26%, 10% and 0% of facilities (excluding facilities where patients were referred out for either drug). Across all countries, in facilities with ART stored on-site, adult ART stock-outs were reported in 3/44 (7%) facilities compared with 10/43 (23%) facility stock-outs of paediatric ART. Laboratory services at primary health facilities were limited: CD4 was used for ART initiation in 4/9, 5/6 and 13/14 in Malawi, Uganda and Zimbabwe respectively, but frequently only in selected patients. Routine viral load monitoring was not used; 6/58 (10%) facilities with ART provision accessed centralised viral loads for selected patients.ConclusionsAlthough coverage of HIV testing, PMTCT and cotrimoxazole prophylaxis was high in all countries, decentralization of ART services was variable and incomplete. Challenges of staffing and stock management were evident. Laboratory testing for toxicity and treatment effectiveness monitoring was not available in most primary level facilities.

Understanding the linkages between informal and formal care for people living with HIV in sub-Saharan Africa

Abstract In response to the human resource challenges facing African health systems, there is increasing involvement of informal care providers in HIV care. Through social and institutional interactions that occur in the delivery of HIV care, linkages between formal and informal systems of care often emerge. Based on a review of studies documenting the relationships between formal and informal HIV care in sub-Saharan Africa, we suggest that linkages can be conceptualised as either ‘actor-oriented’ or ‘systems-oriented’. Studies adopting an actor-oriented focus examine hierarchical working relationships and communication practices among health systems actors, while studies focusing on systems-oriented linkages document the presence, absence or impact of formal inter-institutional partnership agreements. For linkages to be effective, the institutional frameworks within which linkages are formalised, as well as the ground-level interactions of those engaged in care, ought to be considered. However, to date, both actor- and system-oriented linkages appear to be poorly utilised by policy makers to improve HIV care. We suggest that linkages between formal and informal systems of care be considered across health systems, including governance, human resources, health information and service delivery in order to improve access to HIV services, enable knowledge transfer and strengthen health systems.

‘Deep down in their heart, they wish they could be given some incentives’: a qualitative study on the changing roles and relations of care among home-based caregivers in Zambia

BackgroundAcross Sub-Saharan Africa, the roll-out of antiretroviral treatment (ART) has contributed to shifting HIV care towards the management of a chronic health condition. While the balance of professional and lay tasks in HIV caregiving has been significantly altered due to changing skills requirements and task-shifting initiatives, little attention has been given to the effects of these changes on health workers’ motivation and existing care relations.MethodsThis paper draws on a cross-sectional, qualitative study that explored changes in home-based care (HBC) in the light of widespread ART rollout in the Lusaka and Kabwe districts of Zambia. Methods included observation of HBC daily activities, key informant interviews with programme staff from three local HBC organisations (n = 17) and ART clinic staff (n = 8), as well as in-depth interviews with home-based caregivers (n = 48) and HBC clients (n = 31).ResultsSince the roll-out of ART, home-based caregivers spend less time on hands-on physical care and support in the household, and are increasingly involved in specialised tasks supporting their clients’ access and adherence to ART. Despite their pride in gaining technical care skills, caregivers lament their lack of formal recognition through training, remuneration or mobility within the health system. Care relations within homes have also been altered as caregivers’ newly acquired functions of monitoring their clients while on ART are met with some ambivalence. Caregivers are under pressure to meet clients and their families’ demands, although they are no longer able to provide material support formerly associated with donor funding for HBC.ConclusionsAs their responsibilities and working environments are rapidly evolving, caregivers’ motivations are changing. It is essential to identify and address the growing tensions between an idealized rhetoric of altruistic volunteerism in home-based care, and the realities of lay worker deployment in HIV care interventions that not only shift tasks, but transform social and professional relations in ways that may profoundly influence caregivers’ motivation and quality of care.

Exploring the experiences of women and health care workers in the context of PMTCT Option B Plus in Malawi.

Introduction: Malawi has embarked on a “test-and-treat” approach to prevent mother-to-child transmission (PMTCT) of HIV, known as “Option B+,” offering all HIV-infected pregnant and breastfeeding women lifelong antiretroviral therapy (ART) regardless of CD4 count or clinical stage. A cross-sectional qualitative study was conducted to explore early experiences surrounding “Option B+” for patients and health care workers (HCWs) in Malawi. Methods: Study participants were purposively selected across 6 health facilities in 3 regional health zones in Malawi. Semi-structured interviews were conducted with women enrolled in “Option B+” (n = 24), and focus group discussions were conducted with HCWs providing Option B+ services (n = 6 groups of 8 HCWs). Data were analyzed using a qualitative thematic coding framework. Results: Patients and HCWs identified the lack of male involvement as a barrier to retention in care and expressed concerns at the rapidity of the test-and-treat process, which makes it difficult for patients to “digest” a positive diagnosis before starting ART. Fear regarding the breach of privacy and confidentiality were also identified as contributing to loss to follow-up of women initiated under the Option B+. Disclosure remains a difficult process within families and couples. Lifelong ART was also perceived as an opportunity to plan future pregnancies. Conclusions: As “Option B+” continues to be rolled out, novel interventions to support and retain women into care must be implemented. These include providing space, time, and support to accept a diagnosis before starting ART, engaging partners and families, and addressing the need for peer support and confidentiality.

Impact of facility- and community-based peer support models on maternal uptake and retention in Malawi's option B+ HIV prevention of mother-to-child transmission program: A 3-arm cluster randomized controlled trial (PURE Malawi)

Background: Many sub-Saharan African countries have adopted Option B+, a prevention of mother-to-child transmission approach providing HIV-infected pregnant and lactating women with immediate lifelong antiretroviral therapy. High maternal attrition has been observed in Option B+. Peer-based support may improve retention. Methods: A 3-arm stratified cluster randomized controlled trial was conducted in Malawi to assess whether facility- and community-based peer support would improve Option B+ uptake and retention compared with standard of care (SOC). In SOC, no enhancements were made (control). In facility-based and community-based models, peers provided patient education, support groups, and patient tracing. Uptake was defined as attending a second scheduled follow-up visit. Retention was defined as being alive and in-care at 2 years without defaulting. Attrition was defined as death, default, or stopping antiretroviral therapy. Generalized estimating equations were used to estimate risk differences (RDs) in uptake. Cox proportional hazards regression with shared frailties was used to estimate hazard of attrition. Results: Twenty-one facilities were randomized and enrolled 1269 women: 447, 428, and 394 in facilities that implemented SOC, facility-based, and community-based peer support models, respectively. Mean age was 27 years. Uptake was higher in facility-based (86%; RD: 6%, confidence interval [CI]: −3% to 15%) and community-based (90%; RD: 9%, CI: 1% to 18%) models compared with SOC (81%). At 24 months, retention was higher in facility-based (80%; RD: 13%, CI: 1% to 26%) and community-based (83%; RD: 16%, CI: 3% to 30%) models compared with SOC (66%). Conclusions: Facility- and community-based peer support interventions can benefit maternal uptake and retention in Option B+.

Implementation of antiretroviral therapy for life in pregnant/breastfeeding HIV+ women (Option B+) alongside rollout and changing guidelines for ART initiation in rural Zimbabwe: the Lablite Project experience

Background: Lifelong antiretroviral therapy (ART) for pregnant and breastfeeding women (Option B+) was rolled out in Zimbabwe from 2014, with simultaneous raising of the CD4 treatment threshold to 500 cells per cubic millimeter in nonpregnant/breastfeeding adults and children 5 years and over. Methods: Lablite is an implementation project in Zimbabwe, Malawi, and Uganda evaluating ART rollout. Routine patient-level data were collected for 6 months before and 12 months after Option B+ rollout at a district hospital and 3 primary care facilities in Zimbabwe (2 with outreach ART and 1 with no ART provision before Option B+). Results: Between September 2013 and February 2015, there were 1686 ART initiations in the 4 facilities: 91% adults and 9% children younger than 15 years. In the 3 facilities with established ART, initiations rose from 300 during 6 months before Option B+ to 869 (2.9-fold) and 463 (1.5-fold), respectively, 0–6 months and 6–12 months after Option B+. Post-Option B+, an estimated 43% of pregnant/breastfeeding women needed ART for their own health, based on World Health Organization stage 3/4 or CD4 ⩽350 per cubic millimeter (64% for CD4 ⩽500). Seventy-four men (22%) and 123 nonpregnant/breastfeeding women (34%) initiated ART with CD4 >350 after the CD4 threshold increase. Estimated 12-month retention on ART was 79% (69%–87%) in Option B+ women (significantly lower in younger women, P = 0.01) versus 93% (91%–95%) in other adults (difference P < 0.001). Conclusions: There were increased ART initiations in all patient groups after implementation of World Health Organization 2013 guidelines. Retention of Option B+ women was poorer than retention of other adults; younger women require attention because they are more likely to disengage from care.

Viral suppression and HIV drug resistance at 6 months among women in Malawi's option B+ program: Results from the PURE Malawi study

Background: In 2011, Malawi launched Option B+, a program of universal antiretroviral therapy (ART) treatment for pregnant and lactating women to optimize maternal health and prevent pediatric HIV infection. For optimal outcomes, women need to achieve HIVRNA suppression. We report 6-month HIVRNA suppression and HIV drug resistance in the PURE study. Methods: PURE study was a cluster-randomized controlled trial evaluating 3 strategies for promoting uptake and retention; arm 1: Standard of Care, arm 2: Facility Peer Support, and arm 3: Community Peer support. Pregnant and breastfeeding mothers were enrolled and followed according to Malawi ART guidelines. Dried blood spots for HIVRNA testing were collected at 6 months. Samples with ART failure (HIVRNA ≥1000 copies/ml) had resistance testing. We calculated odds ratios for ART failure using generalized estimating equations with a logit link and binomial distribution. Results: We enrolled 1269 women across 21 sites in Southern and Central Malawi. Most enrolled while pregnant (86%) and were WHO stage 1 (95%). At 6 months, 950/1269 (75%) were retained; 833/950 (88%) had HIVRNA testing conducted, and 699/833 (84%) were suppressed. Among those with HIVRNA ≥1000 copies/ml with successful amplification (N = 55, 41% of all viral loads > 1000 copies/ml), confirmed HIV resistance was found in 35% (19/55), primarily to the nonnucleoside reverse transcriptase inhibitor class of drugs. ART failure was associated with treatment default but not study arm, age, WHO stage, or breastfeeding status. Conclusions: Virologic suppression at 6 months was <90% target, but the observed confirmed resistance rates suggest that adherence support should be the primary approach for early failure in option B+.

Village registers for vital registration in rural Malawi

Paper‐based village registers were introduced 5 years ago in Malawi as a tool to measure vital statistics of births and deaths at the population level. However, usage, completeness and accuracy of their content have never been formally evaluated. In Traditional Authority Mwambo, Zomba district, Malawi, we assessed 280 of the 325 village registers with respect to (i) characteristics of village headmen who used village registers, (ii) use and content of village registers, and (iii) whether village registers provided accurate information on births and deaths. All village headpersons used registers. There were 185 (66%) registers that were regarded as 95% completed, and according to the registers, there were 115 840 people living in the villages in the catchment area. In 2011, there were 1753 births recorded in village registers, while 6397 births were recorded in health centre registers in the same catchment area. For the same year, 199 deaths were recorded in village registers, giving crude death rates per 100 000 population of 189 for males and 153 for females. These could not be compared with death rates in health centre registers due to poor and inconsistent recording in these registers, but they were compared with death rates obtained from the 2010 Malawi Demographic Health Survey that reported 880 and 840 per 100 000 for males and females, respectively. In conclusion, this study shows that village registers are a potential source for vital statistics. However, considerable inputs are needed to improve accuracy of births and deaths, and there are no functional systems for the collation and analysis of data at the traditional authority level. Innovative ways to address these challenges are discussed, including the use of solar‐powered electronic village registers and mobile phones, connected with each other and the health facilities and the District Commissioners office through the cellular network and wireless coverage.
