Decentralization of HIV care and treatment services in Central Province, Kenya

Influence of Stigma on Engagement in HIV Care and Adherence to Antiretroviral Therapy in Specialized HIV Clinics Targeting Men Who Have Sex with Men and Transgender Women in Lima, Peru

HIV stigma is a social determinant of health that can influence multiple health outcomes, including adherence to antiretroviral therapy (ART), engagement in HIV care, and viral suppression levels in people with HIV (PWH). In Peru, where the HIV epidemic is concentrated in men who have sex with men (MSM) and transgender women (TGW), stigma may play an important role in healthcare engagement. To understand the relationship between stigma and two outcome variables, ART adherence and engagement in HIV care in 400 MSM and TGW, we assessed factors from the Behavioral Model for Vulnerable Populations at two HIV clinics that tailor services for sexual and gender minorities. While some predisposing, need, and enabling resource factors were associated with optimal (≥ 90%) ART adherence or engagement in HIV care, none of the stigma subscales were correlated, suggesting that when LGBTQ-affirming care is provided to MSM/TGW, stigma may not influence HIV-related outcomes.

Barriers to longitudinal follow-up for hepatitis B treatment in rural Sierra Leone: A mixed methods study of retention in care

HBV disproportionately affects resource-limited settings, and retaining patients in longitudinal care remains challenging. We conducted a mixed methods investigation to understand the causes of losses to follow-up within an HBV clinic in rural Sierra Leone. We developed a multivariable logistic regression model of baseline clinical and sociodemographic factors predicting losses to follow-up, defined as failing to present for a follow-up visit within 14 months of enrollment. We included patients enrolled between April 30, 2019 and March 1, 2020, permitting 14 months of follow-up by April 30, 2021. We then developed a survey to solicit patient perspectives on the challenges surrounding retention. We interviewed randomly selected patients absent from HBV care for at least 6 months. Among 271 patients enrolled in the Kono HBV clinic, 176 (64.9%) did not have a follow-up visit within 14 months of the study end point. Incomplete baseline workup (aOR 2.9; 95% CI: 1.6-4.8), lack of treatment at baseline (aOR 5.0; 95% CI: 1.7-14.4), and having cirrhosis at baseline (aOR 3.3; 95% CI: 0.99-10.8) were independently associated with being lost to follow-up. For the patient survey, 21 patients completed the interview (median age 34 years [IQR: 25-38]). Travel-related factors were the most frequently reported barrier to retention (57%). Almost 30% suggested improved customer care might support retention in care; 24% requested to be given medication. In our setting, factors that might reduce losses to follow-up included expanded criteria for treatment initiation, overcoming transportation barriers, reducing wait times, ensuring against stockouts, and scaling up point-of-care testing services.

"I Have to Do It in Secrecy": Provider Perspectives on HIV Service Delivery and Quality of Care for Key Populations in Zambia

ABSTRACT

Key populations (KPs) experience suboptimal outcomes along the HIV care and prevention continua, but there is limited study of the challenges service providers encounter delivering HIV services to KPs, particularly in settings like Zambia, where provision of these services remains legally ambiguous. Seventy-seven providers completed in-depth interviews exploring constraints to HIV service delivery for KPs and recommendations for improving access and care quality. Thematic analysis identified salient challenges and opportunities to service delivery and quality of care for KPs, spanning interpersonal, institutional, and structural domains. Limited provider training in KP-specific needs was perceived to influence KP disclosure patterns in clinical settings, impeding service quality. The criminalization of KP sexual and drug use behaviors, coupled with perceived institutional and legal ambiguities to providing HIV services to KPs, cultivated unwelcoming service delivery environments for KPs. Findings elucidate opportunities for improving HIV service delivery/quality, from decentralized care to expanded legal protections for KPs and service providers.

Networking community health workers for service integration: role of social media

Community health workers (CHW) can play an active role in providing integrated HIV and harm reduction services. We used social media to create a virtual network among Vietnamese CHW. This paper reports CHW's social media engagement and the relationships with other work-related indicators. Sixty CHW participated in an intervention for integrated HIV/drug use service delivery. Following two in-person sessions, Facebook groups were established for CHW to share information, seek consultation, and refer patients. CHW's levels of online engagements were tracked for six months and linked to their service provision confidence, interaction with patients and other providers, and job satisfaction. The CHW made 181 posts, which received 557 comments and 1,607 reactions during the six months. Among the 60 CHW, 22 (36.6%) had three or more posts, 19 (31.7%) had one or two posts, and 19 (31.7%) had no post. Comparing the baseline and 6-month follow-up data, we observed that those who posted three or more times showed better service provision confidence (p = 0.0081), more interaction with providers in other settings (p = 0.0071), and higher job satisfaction (p = 0.0268). Our study suggests using social media to engage CHW in virtual communications to improve service provision in communities.

An intervention pilot to facilitate harm reduction service decentralization in Vietnam

INTRODUCTION

Harm reduction services, including methadone maintenance therapy (MMT), have been decentralized to Vietnam's community health care settings. This study aims to pilot test an intervention to facilitate decentralized harm reduction service delivery in Vietnam.

METHODS

The research team conducted an intervention pilot between August 2020 and May 2021 with six community MMT distribution sites in Thai Nguyen Province of Vietnam. We recruited five commune health workers (CHW) from each center (N = 30). In-person intervention training included content to correct misconceptions about harm reduction and reduce stigmatizing attitudes toward patients who use drugs and teach CHWs to self-examine and improve their service provision process. The study team developed a web-based platform to streamline CHW's patient monitoring and referral efforts. The team assessed intervention outcomes at baseline, 3-, and 6-months. CHWs in the intervention group provided acceptability ratings and feedback on the intervention at 6-months.

RESULTS

CHWs in both intervention and control groups had similar background characteristics and outcome measures at baseline. CHWs in the intervention group, compared to those in the control group, showed a significantly higher level of improvement in adherence to service delivery protocol at 3-months. CHW in the intervention group had a significantly lower level of management-related stress compared to the control group at 6-months, although the intervention effect measured by the difference in change from baseline was not statistically significant. CHWs who participated in the final focus group reported high acceptability of the intervention.

CONCLUSION

This intervention pilot demonstrated acceptability and promising outcomes on community-based harm reduction service delivery. Similar intervention strategies can be applied to enhance the decentralization of other chronic disease treatment services.

HIV-related stigma and discrimination among health care workers during early program decentralization in rural district Gunungkidul, Indonesia: a cross-sectional study

BACKGROUND

Expanding HIV services by decentralizing provision to primary care raises a possible concern of HIV-related stigma and discrimination (SAD) from health care workers (HCWs) as new service points gain experience in HIV care delivery during early implementation. We surveyed indicators and examined the correlates of HIV-related SAD among HCWs in a decentralizing district of rural Gunungkidul, Indonesia.

METHODS

We conducted a cross-sectional survey on a random stratified sample of 234 HCWs in 14 public health facilities (one district hospital, 13 primary health centers [PHC]) during the second year of decentralization roll-out in the district. We computed the prevalence of SAD indicators and used multivariable logistic regression to identify the correlates of these SAD indicators.

RESULTS

The prevalence of SAD among HCWs was similarly high between hospital and PHC HCWs for fear of HIV transmission (~71%) and perceived negative image of PHIV (~75%). Hospital HCWs exhibited somewhat lower avoidance of service duties (52.6% vs. 63.7%; p = 0.088) with weak evidence of a difference and significantly higher levels of discriminatory practice (96.1% vs. 85.6%; p = 0.009) than those working in PHCs. Recent interactions with PLHIV and receipt of training lowered the odds of fear of HIV transmission (p <0.021). However, the odds of avoiding care duties increased with receipt of training (p =0.003) and decreased for hospital HCWs (p = 0.030). HIV knowledge lowered the odds of discriminatory practice (p = 0.002), but hospital facility and nurse/midwife cadres were associated with increased odds of discriminatory practices (p <0.021). No significant correlate was found for perceived negative image of PLHIV.

CONCLUSION

HIV-related SAD among HCWs can be prevalent during early decentralization, highlighting the need for timely or preparatory interventions with a focus on building the capacity of hospital and non-physician workforce for positive patient-provider interactions when delivering HIV care.

User perspectives and preferences on a novel TB LAM diagnostic (Fujifilm SILVAMP TB LAM)-a qualitative study in Malawi and Zambia

Widely available tuberculosis (TB) diagnostics use sputum samples. However, many patients, particularly children and patients living with HIV (PLHIV), struggle to provide sputum. Urine diagnostics are a promising approach to circumvent this challenge while delivering reliable and timely diagnosis. This qualitative study in two high TB/HIV burden countries assesses values and preferences of end-users, along with potential barriers for the implementation of the novel Fujifilm SILVAMP TB-LAM (FujiLAM, Fujifilm, Japan) urine test. Between September 2020 and March 2021, we conducted 42 semi-structured interviews with patients, health care providers (HCPs) and decision makers (DMs) (e.g., in national TB programs) in Malawi and Zambia. Interviews were transcribed verbatim and analyzed using a framework approach supported by NVIVO. Findings aligned with the pre-existing Health Equity Implementation Framework, which guided the presentation of results. The ease and convenience of urine-based testing was described as empowering among patients and HCPs who lamented the difficulty of sputum collection, however HCPs expressed concerns that a shift in agency to the patient may affect clinic workflows (e.g., due to less control over collection). Implementation facilitators, such as shorter turnaround times, were welcomed by operators and patients alike. The decentralization of diagnostics was considered possible with FujiLAM by HCPs and DMs due to low infrastructure requirements. Finally, our findings support efforts for eliminating the CD4 count as an eligibility criterion for LAM testing, to facilitate implementation and benefit a wider range of patients. Our study identified barriers and facilitators relevant to scale-up of urine LAM tests in Malawi and Zambia. FujiLAM could positively impact health equity, as it would particularly benefit patient groups currently underserved by existing TB diagnostics. Participants view the approach as a viable, acceptable, and likely sustainable option in low- and middle-income countries, though adaptations may be required to current health care processes for deployment.

Research priorities for accelerating the achievement of three 95 HIV goals in Cameroon: a consensus statement from the Cameroon HIV Research Forum (CAM-HERO)

INTRODUCTION

the Treat-All remains the globally endorsed approach to attain the 95-95-95 targets and end the AIDS pandemic by 2030, but requires some country-level contextualization. In Cameroon, the specific research agenda to inform strategies for improving HIV policy was yet to be defined.

METHODS

under the patronage of the Cameroon Ministry of health, researchers, policy makers, implementing partners, and clinicians from 13 institutions, used the Delphi method to arrive at a consensus of HIV research priorities. The process had five steps: 1) independent literature scan by 5 working groups; 2) review of the initial priority list; 3) appraisal of priorities list in a larger group; 4) refinement and consolidation by a consensus group; 5) rating of top research priorities.

RESULTS

five research priorities and corresponding research approaches, resulted from the process. These include: 1) effectiveness, safety and active toxicity monitoring of new and old antiretrovirals; 2) outcomes of Antiretroviral Therapy (ART) with focus in children and adolescents; 3) impact of HIV and ART on aging and major chronic diseases; 4) ART dispensation models and impact on adherence and retention; 5) evaluations of HIV treatment and prevention programs.

CONCLUSION

the research priorities resulted from a consensus amongst a multidisciplinary team and were based on current data about the pandemic and science to prevent, treat, and ultimately cure HIV. These priorities highlighted critical areas of investigation with potential relevance for the country, funders, and regulatory bodies.

Long-Distance Travel for HIV-Related Care-Burden or Choice?: A Mixed Methods Study in Tanzania

Decentralization of HIV care across sub-Saharan Africa has increased access to anti-retroviral therapy (ART). Although traveling for care has traditionally been viewed as a barrier, some individuals may choose to travel for care due to stigma and fear of HIV status disclosure. We sought to understand the prevalence of traveling long distances for HIV care, as well as reasons for engaging in such travel. Using a concurrent embedded mixed-methods study design, individuals receiving care at two HIV care and treatment clinics in Tanzania completed a quantitative survey (n = 196), and a sub-set of participants reporting long-distance travel for care were interviewed (n = 31). Overall 58.2% of participants (n = 114/196) reported knowing of a closer clinic than the one they chose to attend. Having experienced enacted stigma was significantly associated with traveling for care (OR 2.31, 95% CI 1.12, 4.75, p = 0.02). Reasons for clinic choice centered on three main themes: clinic familiarity, quality of care, and stigma. Traveling for care was often viewed as an enabling strategy for remaining engaged in care by helping overcome other barriers, including stigma and suboptimal quality of care.

The initiation of human immunodeficiency virus treatment for children at different levels of care

Background: The human immunodeficiency virus (HIV) pandemic increased the demand for health care resources in South Africa. To decrease the burden on specialised facilities, the Department of Health decentralised antiretroviral (ARV) management. In the uMgungundlovu district, adult HIV primary care services reported lower rates of HIV viral load (VL) suppression after initiation of ARVs compared to other levels of care. The aim of the study was to evaluate paediatric HIV services in the same district. Methods: Four ARV clinics, at different levels of care, initiating and monitoring paediatric HIV infection treatment in uMgungundlovu district, KwaZulu Natal, were selected: primary healthcare services, general practitioner services, general paediatric services and subspecialist infectious diseases services were included. Paediatric patients newly diagnosed between January 2014 and June 2015 were included in the study. The rate of HIV VL suppression at one year after treatment initiation was the primary outcome measure. A total of 377 patients were included, 35 at the nurse-led primary care clinic, 25 at the general practitioner-led primary care clinic, 156 at the paediatrician-led secondary care clinic, and 161 at the HIV paediatric subspecialist-led tertiary care clinic. Of the 377 patients, 154 (59.9%) achieved VL suppression at one year, with 75% (18/24), 61.9% (13/21), 51.7% (60/116) and 66.7% (63/96) achieving HIV VL suppression at the four clinic types, respectively. Conclusion: HIV VL suppression rates were variable, but did not differ statistically across levels of health care. Outcomes were not improved by initiation in specialist or subspecialist-led clinics, which supports the strategy of increasing access by decentralising HIV care for paediatric patients.

Patient and nurse perspectives of a nurse-led community-based model of HIV care delivery in Malawi: a qualitative study

Background

Differentiated models of care (DMOC) are used to make antiretroviral therapy (ART) accessible to people living with HIV (PLHIV). In Malawi, Lighthouse Trust has piloted various DMOCs aimed at providing quality care while reducing personal and logistical barriers when accessing clinic-based healthcare. One of the approaches was community-based provision of ART by nurses to stable patients.

Methods

To explore how the nurse-led community ART programme (NCAP) is perceived, we interviewed eighteen purposively selected patients receiving ART through NCAP and the four nurses providing the community-based health care. Information obtained from them was complemented with observations by the study team. Interviews were recorded and transcribed. Data was analysed using manual coding and thematic analysis.

Results

Through the NCAP, patients were able to save money on transportation and the time it took them to travel to a health facility. Caseloads and waiting times were also reduced, which made patients more comfortable and gave nurses the time to conduct thorough consultations. Closer relationships were built between patients and care providers, creating a space for more open conversations (although this required care providers to set clear boundaries and stick to schedule).

Patients’ nutritional needs and concerns related to stigma remain a concern, while operational issues affect the quality of the services provided in the community. Considerations for community-led healthcare programmes include the provision of transportation for care providers; the physical structure of community sites (in regard to private spaces); the timely consolidation of data collected in the field to a central database; and the need for care providers to cover multiple facility-based staff roles.

Conclusions

The patients interviewed in this study preferred the NCAP approach to the facility-based model of care because it saved them money on transport, reduced waiting-times, and allowed for a more thorough consultation, while continuing to provide quality HIV care. However, when considering a community-level DMOC approach, certain factors – including staff transportation and workload – must be taken into consideration and purposefully planned.

The effects of decentralising antiretroviral therapy care delivery on health outcomes for adolescents and young adults in low- and middle-income countries: a systematic review

Background: Decentralisation of antiretroviral therapy has been implemented to scale up HIV care provision for patients in resource-limited countries. Youth living with HIV demonstrate the poorest care outcomes, compared to other age groups. Objectives: To systematically evaluate evidence on the effects of decentralising facility-based HIV care on care outcomes for youth living with HIV in low- and middle-income countries. Methods: A systematic review was conducted through 12 electronic databases of peer-reviewed articles, conference abstracts, and grey literature; contacting relevant experts; and hand-searching references. Records were included if they were published after 1 January 1996 (advent of triple-drug ART) and reported health outcomes for decentralised and centralised care, separately, or evaluated the effect of decentralised care on care outcomes. Two authors independently screened search results. When age-disaggregated data (10-24 years old) were required for inclusion, we contacted study authors for data abstraction. Implementation fidelity of decentralisation, study quality, and risk of bias was assessed using the TIDieR checklist, CASP checklists, and ROBINS-I tool, respectively. Results: Of 11 potentially eligible studies, two studies from sub-Saharan Africa met inclusion criteria after data disaggregation by age. The studies and abstracted data were insufficiently homogenous in implementation and study design to justify meta-analysis. However, evidence suggests the potential for decentralised care to result in at least equivalent attrition-related outcomes (retention in care and mortality) for youth within decentralised HIV care. Limited sample size and significant selection and allocation bias confound clear, generalisable conclusions for youth living with HIV in resource-limited settings. Conclusions: There is a paucity of evidence for the effects of decentralising HIV care for youth living in resource-limited settings, particularly recent evidence reflective of the current HIV care landscape. Further work is required to rigorously analyse the effects of decentralising HIV care to inform policymakers and care providers, particularly as demand for HIV care in this population grows.

PMTCT care cascade and factors associated with attrition in the first four years after Option B+ implementation in Mozambique

OBJECTIVE

To evaluate the effectiveness of the prevention of mother-to-child transmission (PMTCT) Option B+ programme in two provinces with high human immunodeficiency virus (HIV) burden in Mozambique over the first four years of programme implementation.

METHODS

We assessed the PMTCT cascade in antenatal care (ANC) from July 2013 to December 2017 using facility-level data and performed a retrospective cohort analysis with patient-level data. We compared the 12-month antiretroviral therapy (ART) retention rates between women with HIV infection who initiated ART under Option B+ ('B+ pregnant') and those who initiated ART for their own health ('own health').

RESULTS

A total of 916 280 pregnant women enrolled in ANC. The proportion of women with a documented HIV status increased from 93% in 2013 to 96% in 2017. The proportion of those tested HIV-positive decreased from 8% to 6% while that of those HIV-positive on ART increased from 42% to 95%. Of the 44 377 HIV-positive women included in the analysis, 35% were lost to care. 'B+ pregnant' women initiating ART in 2015 were less likely to have no follow-up (NFU) compared with 'own health' women starting ART during the same period (adjusted odds ratio: 0.77, 95% confidence interval [CI]: 0.64-0.94, P = 0.01). There was no statistical difference between the two groups during the other years in which ART was initiated. Of those returning for care after their first visit (N = 39 801), the 'B+ pregnant' women showed a higher risk of non-retention than the other group (adjusted hazard ratio: 1.14, 95% CI: 1.03-1.25) when ART was initiated in 2013. The risk decreased during the subsequent years, with no difference observed between the groups.

CONCLUSION

PMTCT Option B+ programme scale-up has yielded positive results, including the maintenance of high HIV testing and ART initiation rates in ANC. Challenges still remain, however, in improving immediate engagement in care and long-term retention. Seeking alternative service delivery models to support existing health systems and prevent defaulters is required to achieve the UNAIDS 95-95-95 targets for PMTCT in Mozambique.

VIBRA trial - Effect of village-based refill of ART following home-based same-day ART initiation vs clinic-based ART refill on viral suppression among individuals living with HIV: protocol of a cluster-randomized clinical trial in rural Lesotho

BACKGROUND

There is a need for evaluating community-based antiretroviral therapy (ART) delivery models to improve overall performance of HIV programs, specifically in populations that may have difficulties to access continuous care. This cluster-randomized clinical trial aims to evaluate the effectiveness of a multicomponent differentiated ART delivery model (VIBRA model) after home-based same-day ART initiation in remote villages in Lesotho, southern Africa.

METHODS/DESIGN

The VIBRA trial (VIllage-Based Refill of ART) is a cluster-randomized parallel-group superiority clinical trial conducted in two districts in Lesotho, southern Africa. Clusters (i.e., villages) are randomly assigned to either the VIBRA model or standard care. The clusters are stratified by district, village size, and village access to the nearest health facility. Eligible individuals (HIV-positive, aged 10 years or older, and not taking ART) identified during community-based HIV testing campaigns are offered same-day home-based ART initiation. The intervention clusters offer a differentiated ART delivery package with two features: (1) drug refills and follow-ups by trained and supervised village health workers (VHWs) and (2) the option of receiving individually tailored adherence reminders and notifications of viral load results via SMS. The control clusters will continue to receive standard care, i.e., collecting ART refills from a clinic and no SMS notifications. The primary endpoint is viral suppression 12 months after enrolment. Secondary endpoints include linkage to and engagement in care. Furthermore, safety and cost-effectiveness analyses plus qualitative research are planned. The minimum target sample size is 262 participants. The statistical analyses will follow the CONSORT guidelines. The VIBRA trial is linked to another trial, the HOSENG (HOme-based SElf-testiNG) trial, both of which are within the GET ON (GETing tOwards Ninety) research project.

DISCUSSION

The VIBRA trial is among the first to evaluate the delivery of ART by VHWs immediately after ART initiation. It assesses the entire HIV care cascade from testing to viral suppression. As most countries in sub-Saharan Africa have cadres like the VHW program in Lesotho, this model-if shown to be effective-has the potential to be scaled up. The system impact evaluation will provide valuable cost estimations, and the qualitative research will suggest how the model could be further modified to optimize its impact.

Patient-level benefits associated with decentralization of antiretroviral therapy services to primary health facilities in Malawi and Uganda

Background

The Lablite project captured information on access to antiretroviral therapy (ART) at larger health facilities ('hubs') and lower-level health facilities ('spokes') in Phalombe district, Malawi and in Kalungu district, Uganda.

Methods

We conducted a cross-sectional survey among patients who had transferred to a spoke after treatment initiation (Malawi, n=54; Uganda, n=33), patients who initiated treatment at a spoke (Malawi, n=50; Uganda, n=44) and patients receiving treatment at a hub (Malawi, n=44; Uganda, n=46).

Results

In Malawi, 47% of patients mapped to the two lowest wealth quintiles (Q1-Q2); patients at spokes were poorer than at a hub (57% vs 23% in Q1-Q2; p<0.001). In Uganda, 7% of patients mapped to Q1-Q2; patients at the rural spoke were poorer than at the two peri-urban facilities (15% vs 4% in Q1-Q2; p<0.001). The median travel time one way to a current ART facility was 60 min (IQR 30-120) in Malawi and 30 min (IQR 20-60) in Uganda. Patients who had transferred to the spokes reported a median reduction in travel time of 90 min in Malawi and 30 min in Uganda, with reductions in distance and food costs.

Conclusions

Decentralizing ART improves access to treatment. Community-level access to treatment should be considered to further minimize costs and time.

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 multi-site community randomized trial of community health workers to provide counseling and support for patients newly entering HIV care in rural Ethiopia: study design and baseline implementation

BACKGROUND

Although HIV therapy is delivered to millions globally, treatment default (especially soon after entering care) remains a challenge. Community health workers (CHWs) can provide many services for people with HIV, including in rural and resource-limited settings.

OBJECTIVES

We designed and implemented a 32 site community randomized trial throughout southern Ethiopia to assess an intervention using CHWs to improve retention in HIV care.

METHODS

Sixteen district hospital and 16 local health center HIV clinics were randomized 1:1 to be intervention or control sites. From each site, we enrolled adults newly entering HIV care. Participants at intervention sites were assigned a CHW who provided: HIV and health education; counseling and social support; and facilitated communication with HIV clinics. All participants are followed through three years with annual health surveys, plus HIV clinic record abstraction including clinic visit dates. CHWs record operational data about their client contacts.

RESULTS

1799 HIV patients meeting inclusion criteria were enrolled and randomized: 59% were female, median age = 32 years, median CD4 + count = 263 cells/mm³, and 41% were WHO Stage III or IV. A major enrollment challenge was fewer new HIV patients initiating care at participating sites due to shortage of HIV test kits. At intervention sites, 71 CHWs were hired, trained and assigned to clients. In meeting with clients, CHWs needed to accommodate to various challenges, including HIV stigma, distance, and clients lacking cell phones.

CONCLUSIONS

This randomized community HIV trial using CHWs in a resource-limited setting was successfully launched, but required flexibility to adapt to unforeseen challenges.

Review of differentiated approaches to antiretroviral therapy distribution

In response to global trends of maximizing the number of patients receiving antiretroviral therapy (ART), this review summarizes literature describing differentiated models of ART distribution at facility and community levels in order to highlight promising strategies and identify evidence gaps. Databases and gray literature were searched, yielding thirteen final articles on differentiated ART distribution models supporting stable adult patients. Of these, seven articles focused on distribution at facility level and six at community level. Findings suggest that differentiated models of ART distribution contribute to higher retention, lower attrition, and less loss to follow-up (LTFU). These models also reduced patient wait time, travel costs, and time lost from work for drug pick-up. Facility- and community-level ART distribution models have the potential to extend treatment availability, enable improved access and adherence among people living with HIV (PLHIV), and facilitate retention in treatment and care. Gaps remain in understanding the desirability of these models for PLHIV, and the need for more information the negative and positive impacts of stigma, and identifying models to reach traditionally marginalized groups such as key populations and youth. Replicating differentiated care so efforts can reach more PLHIV will be critical to scaling these approaches across varying contexts.

The WHO public health approach to HIV treatment and care: looking back and looking ahead

In 2006, WHO set forth its vision for a public health approach to delivering antiretroviral therapy. This approach has been broadly adopted in resource-poor settings and has provided the foundation for scaling up treatment to over 19·5 million people. There is a global commitment to end the AIDS epidemic as a public health threat by 2030 and, to support this goal, there are opportunities to adapt the public health approach to meet the ensuing challenges. These challenges include the need to improve identification of people with HIV infection through expanded approaches to testing; further simplify and improve treatment and laboratory monitoring; adapt the public health approach to concentrated epidemics; and link HIV testing, treatment, and care to HIV prevention. Implementation of these key public health principles will bring countries closer to the goals of controlling the HIV epidemic and providing universal health coverage.

Impact of decentralisation of antiretroviral therapy services on HIV testing and care at a population level in Agago District in rural Northern Uganda: results from the Lablite population surveys

Background

We conducted unlinked cross-sectional population-based surveys in Northern Uganda before and after antiretroviral therapy (ART) provision (including Option B+ [lifelong ART for pregnant/breast-feeding women]) at a local primary care facility (Lira Kato Health Centre [HC]). Prior to decentralisation, people travelled 56-76 km round-trip for ART; we aimed to evaluate changes in uptake of HIV-testing, ART coverage and access to ART following decentralisation.

Methods

A total of 2124 adults in 1351 households in two parishes closest to Lira Kato HC were interviewed using questionnaires between March and April 2013 and 2123 adults in 1229 households between January and March 2015.

Results

Adults reporting HIV-testing in the last year increased from 1077/2124 (50.7%) to 1298/2123 (61.1%) between surveys (p<0.001). ART coverage increased from 74/136 (54.4%) self-reported HIV-positive adults in 2013 to 108/133 (81.2%) in 2015 (p<0.001). Post-decentralisation, 47/108 (43.5%) of those on ART were in care at Lira Kato HC (including 37 new initiations). Most of the remainder (47/61, 77%) started ART prior to any ART provision at Lira Kato HC; the most common reason given for not accessing ART locally was concern about drug-stock-outs (30/59, 51%).

Conclusions

HIV-testing and ART coverage increased after decentralisation combined with Option B+ roll-out. However, patients on ART before decentralisation were reluctant to transfer to their local facility.

Outcomes among HIV-infected children initiating HIV care and antiretroviral treatment in Ethiopia

OBJECTIVE

To describe pediatric ART scale-up in Ethiopia, one of the 21 global priority countries for elimination of pediatric HIV infection.

METHODS

A descriptive analysis of routinely collected HIV care and treatment data on HIV-infected children (<15 years) enrolled at 70 health facilities in four regions in Ethiopia, January 2006-September 2013. Characteristics at enrollment and ART initiation are described along with outcomes at 1 year after enrollment. Among children who initiated ART, cumulative incidence of death and loss to follow-up (LTF) were estimated using survival analysis.

RESULTS

11 695 children 0-14 years were enrolled in HIV care and 6815 (58.3%) initiated ART. At enrollment, 31.2% were WHO stage III and 6.3% stage IV. The majority (87.9%) were enrolled in secondary or tertiary facilities. At 1 year after enrollment, 17.9% of children were LTF prior to ART initiation. Among children initiating ART, cumulative incidence of death was 3.4%, 4.1% and 4.8%, and cumulative incidence of LTF was 7.7%, 11.8% and 16.6% at 6, 12 and 24 months, respectively. Children <2 years had higher risk of LTF and death than older children (P < 0.0001). Children with more advanced disease and those enrolled in rural settings were more likely to die. Children enrolled in more recent years were less likely to die but more likely to be LTF.

CONCLUSIONS

Over the last decade large numbers of HIV-infected children have been successfully enrolled in HIV care and initiated on ART in Ethiopia. Retention prior to and after ART initiation remains a major challenge.

Assessment of the World Health Organization's HIV Drug Resistance Early Warning Indicators in Main and Decentralized Outreach Antiretroviral Therapy Sites in Namibia

BACKGROUND

The World Health Organization (WHO) early warning indicators (EWIs) of HIV drug resistance (HIVDR) assess factors at individual ART sites that are known to create situations favourable to the emergence of HIVDR.

METHODS

In 2014, the Namibia HIV care and treatment program abstracted the following adult and pediatric EWIs from all public ART sites (50 main sites and 143 outreach sites): On-time pill pick-up, Retention in care, Pharmacy stock-outs, Dispensing practices, and Viral load suppression. Comparisons were made between main and outreach sites and between 2014 and 2012 using the Wilcoxon signed-rank test in a matched analysis.

RESULTS

The national estimates were: On-time pill pick-up 81.9% (95% CI 81.1-82.8) for adults and 82.4% (81.3-83.4) for pediatrics, Retention in care 79% retained on ART after 12 months for adults and 82% for pediatrics, Pharmacy stock-outs 94% of months without a stock-out for adults and 88% for pediatrics, and Dispensing practices 0.01% (0.001-0.056) dispensed mono- or dual-therapy for adults and 0.01% (0.001-0.069) for pediatrics. Viral load suppression was significantly affected by low rates of Viral load completion. Main sites had higher On-time pill pick-up than outreach sites for adults (p<0.001) and pediatrics (p<0.001), and no difference between main and outreach sites for Retention in care for adults (p = 0.761) or pediatrics (p = 0.214). From 2012 to 2014 in adult sites, On-time pill pick-up (p = 0.001), Retention in care (p<0.001), and Pharmacy stock-outs (p = 0.002) worsened. In pediatric sites, On-time pill pick-up (p<0.001) and Pharmacy stock-outs (p = 0.012) worsened.

CONCLUSIONS

Results of EWIs monitoring in Namibia provide evidence about ART programmatic functioning and contextualize results from national surveys of HIVDR. These results are worrisome as they show a decline in program performance over time. The national ART program is taking steps to minimize the emergence of HIVDR by strengthening adherence and retention of patients on ART, reducing stock-outs, and strengthening ART data quality.

Structure and quality of outpatient care for people living with an HIV infection

Policy-makers and clinicians are faced with a gap of evidence to guide policy on standards for HIV outpatient care. Ongoing debates include which settings of care improve health outcomes, and how many HIV-infected patients a health-care provider should treat to gain and maintain expertise. In this article, we evaluate the studies that link health-care facility and care provider characteristics (i.e., structural factors) to health outcomes in HIV-infected patients. We searched the electronic databases MEDLINE, PUBMED, and EMBASE from inception until 1 January 2015. We included a total of 28 observational studies that were conducted after the introduction of combination antiretroviral therapy in 1996. Three aspects of the available research linking the structure to quality of HIV outpatient care were evaluated: (1) assessed structural characteristics (i.e., health-care facility and care provider characteristics); (2) measures of quality of HIV outpatient care; and (3) reported associations between structural characteristics and quality of care. Rather than scarcity of data, it is the diversity in methodology in the identified studies and the inconsistency of their results that led us to the conclusion that the scientific evidence is too weak to guide policy in HIV outpatient care. We provide recommendations on how to address this heterogeneity in future studies and offer specific suggestions for further reading that could be of interest for clinicians and researchers.

Loss to follow-up among youth accessing outpatient HIV care and treatment services in Kisumu, Kenya

Youth are particularly vulnerable to acquiring HIV, yet reaching them with HIV prevention interventions and engaging and retaining those infected in care and treatment remains a challenge. We sought to determine the incidence rate of loss to follow-up (LTFU) and explore socio-demographic and clinical characteristics associated with LTFU among HIV-positive youth aged 15-21 years accessing outpatient care and treatment clinics in Kisumu, Kenya. Between July 2007 and September 2010, youth were enrolled into two different HIV care and treatment clinics, one youth specific and the other family oriented. An individual was defined as LTFU when absent from the HIV treatment clinic for ≥ 4 months regardless of their antiretroviral treatment status. The incidence rate of LTFU was calculated and Cox regression analysis used to identify factors associated with LTFU. A total of 924 youth (79% female) were enrolled, with a median age of 20 years (IQR 18-21). Over half, (529 (57%)), were documented as LTFU, of whom 139 (26%) were LTFU immediately after enrolment. The overall incidence rate of LTFU was 52.9 per 100 person-years (p-y). Factors associated with LTFU were pregnancy during the study period (crude HR 0.68, 95% CI 0.53-0.89); CD4 cell count >350 (adjusted hazard ratios (AHR) 0.59, 95% CI 0.39-0.90); not being on antiretroviral therapy (AHR 4.0, 95% CI 2.70-5.88); and non-disclosure of HIV infection status (AHR 1.43, 95% CI 1.10-1.89). The clinic of enrolment, age, marital status, employment status, WHO clinical disease stage and education level were not associated with LTFU. Interventions to identify and enrol youth into care earlier, support disclosure, and initiate ART earlier may improve retention of youth and need further investigation. Further research is also needed to explore the reasons for LTFU from care among HIV-infected youth and the true outcomes of these patients.

Knowledge about cervical cancer screening and perception of risk among women attending outpatient clinics in rural Kenya

OBJECTIVE

To evaluate cervical cancer knowledge, risk perception, and screening intention among women attending outpatient clinics in rural Kenya.

METHODS

A cross-sectional oral survey was conducted among non-pregnant women aged 23-64 years who attended one of 11 western Kenyan health facilities for any reason between March 25 and April 26, 2013. Demographic and clinical predictors were identified using bivariate and multivariate regression analyses.

RESULTS

Among 419 participants, 327 (78.0%) had heard of cervical cancer screening. Nevertheless, their specific knowledge was low (mean score 8.6±2.4 [out of 15.0]). Overall, 288 (68.7%) women felt at risk for cervical cancer, and 333 (79.5%) stated that they would undergo screening if offered. Women who intended to undergo screening were less likely to attend a district hospital (adjusted odds ratio [AOR] 0.4; 95% confidence interval [CI] 0.2-0.6) and more likely to have been diagnosed with HIV more than 4 years previously (AOR 0.4; 95% CI 0.2-0.6). Additionally, increased screening acceptance was associated with high knowledge scores (P=0.004).

CONCLUSION

Educational interventions to increase knowledge about cervical cancer might increase screening uptake in low-income settings. Additionally, improvements in services at local health facilities could have a large effect.
