Optimizing differentiated treatment models for people living with HIV in urban Zimbabwe: Findings from a mixed methods study

Experiences and Preferences in Zambia and South Africa for Delivery of HIV Treatment During a Client's First Six Months: Results of the PREFER Study's Cross-Sectional Baseline Survey

Disengagement from antiretroviral therapy (ART) is highest in the early treatment period (≤ 6 months after initiation/re-initiation), but low intensity models designed to increase retention generally exclude these clients. We describe client preferences for HIV service delivery in the early treatment period. From 9/2022 to 6/2023, we surveyed adult clients who were initiating or on ART for ≤ 6 months at primary health facilities in South Africa and Zambia. We collected data on experiences with and preferences for HIV treatment. We enrolled 1,098 participants in South Africa (72% female, median age 33) and 771 in Zambia (67% female, median age 32), 38% and 34% of whom were initiating/re-initiating ART in each country, respectively. While clients expressed varied preferences, most participants (94% in South Africa, 87% in Zambia) were not offered choices regarding service delivery. 82% of participants in South Africa and 36% in Zambia reported receiving a 1-month supply of medication at their most recent visit; however, South African participants preferred 2- or 3-month dispensing (69%), while Zambian participants preferred 3-or 6-month dispensing (85%). Many South African participants (65%) would prefer to collect medication in community settings, while Zambian participants (70%) preferred clinic-based collection. Half of participants desired more one-on-one counselling and health information. Most participants reported positive experiences with providers, but long waiting queues were reported by South African participants.During the first six months on ART, many clients would prefer less frequent clinic visits, longer dispensing intervals, and frequent, high-quality counselling. Care models for the early treatment period should reflect these preferences.Registration: Clinicaltrials.gov NCT05454839, Clinicaltrials.gov NCT05454852.

The Evolving Landscape of Discrete Choice Experiments in Health Economics: A Systematic Review

INTRODUCTION

Stakeholder preference evaluations are increasingly emphasized in healthcare policy and health technology assessment. Discrete choice experiments (DCEs) are the most common method for quantifying preferences among patients, the public, and healthcare professionals. While prior reviews (1990-2017) have examined DCE trends, no comprehensive synthesis exists for studies published since 2018. This updated review (2018-2023) provides critical insights into evolving methodologies and global trends in health-related DCEs.

METHODS

A systematic search (2018-2023) of Medline, Embase, and Web of Science identified relevant studies. Studies were screened for inclusion and data were extracted, including details on DCE design and analysis. To enable trend comparisons, the search strategy and extraction items aligned with previous reviews.

RESULTS

Of 2663 identified papers, 1279 met the inclusion criteria, reflecting a significant rise in published DCEs over time. DCEs were conducted globally, with a remarkable increase in publications from Asia and Africa compared with previous reviews. Experimental designs and econometric models have advanced, continuing prior trends. Notably, most recent DCEs were administered online.

DISCUSSION

The rapid growth of DCE applications underscores their importance in health research. While the methodology is advancing rapidly, it is crucial that researchers provide full transparency in reporting their methods, particularly in detailing experimental designs and validity tests, which are too often overlooked. Key recommendations include improving reporting of experimental designs, applying validity tests, following good practices for presenting benefit-risk attributes, and adopting open science practices. Ensuring methodological rigor will maximize the impact and reproducibility of DCE research in health economics.

Attribute Development in Health-Related Discrete Choice Experiments: A Systematic Review of Qualitative Methods and Techniques to Inform Quantitative Instruments

OBJECTIVES

This review sought to identify the qualitative methods and techniques that researchers have used in the past decade to develop attributes and inform health-related discrete choice experiments (DCEs) surveys from a patient perspective.

METHODS

The review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for reporting systematic reviews. An adapted appraisal tool following guidelines for reporting qualitative research for quantitative instruments and criteria for attribute development in DCEs was applied for quality assessment and data extraction. A narrative approach was used to synthesize data. This examination included consideration of issues pertaining to sampling, data collection, data analysis, attribute list reduction, wording, methodological adaptations to capture patient preferences, and testing the pre-experimental design decisions of the DCE survey.

RESULTS

Of 8505 articles identified for abstract screening, 680 were included for full-text screening, 36 of which met the inclusion criteria. Practices to improve methodological robustness included pre-data collection materials to inform instruments, data collection methods specific for decision-making scenarios, purposeful selection of data analysis methods to address the research question, and participants' involvement in reducing the list of attributes. Examples of methodological adaptations for patients were noted.

CONCLUSIONS

DCEs have the potential to become a mixed-method approach in which the qualitative phase informs a reduced list of attributes for a survey, serves the predesign decisions of the experiment by testing trade-offs, overlapping, understandability, face, and content validity and provides explanations of the quantitative results. Establishing guidelines for using qualitative methods for DCE attribute development may help to broadly enhance the methodological robustness of DCEs.

Prevalence and Risk Factors of HIV Drug Resistance in Zimbabwe: Evidence from Zimbabwe Population-Based HIV Impact Assessment (ZIMPHIA) 2020 Survey

(1) Background: HIV drug resistance (HIVDR) poses a significant challenge to the effectiveness of antiretroviral therapy and the overall management of HIVand AIDS. Understanding the predictors of HIVDR is critical for developing strategies to mitigate its impact. The objectives of this study were to identify the predictors of HIVDR among Zimbabwe Population-Based HIV Impact Assessment (ZIMPHIA 2020) study participants, a national population-based survey. (2) Methods: Data from people living with HIV who participated in the ZIMPHIA 2020 were used to determine the predictors of HIVDR. (3) Results: The prevalence of HIVDR was 44.9%. Acquired HIVDR was present in 76.1% of people with a virological failure and transmitted resistance is 22.6% in naïve individuals. Factors associated with HIVDR in adjusted analysis were the number of lifetime sexual partners (aOR = 1.03, 95% CI: 1.01-1.06, p = 0.017), each additional year since the first HIV positive result (aOR = 1.17, 95% CI: 1.09-1.25, p < 0.01), each additional year on ART (aOR = 1.14, 95% CI: 1.06-1.23, p = 0.001), initiating ART before 2014 (aOR = 3.08, 95% CI: 1.72-5.49, p = 0.020), ever had switched antiretrovirals (aOR = 2.47, 95% CI: 1.15-5.29, p = 0.020) or had ever had a viral load test (aOR = 2.54, 95% CI: 1.54-4.17, p < 0.001) and a CD4 count < 350 (aOR = 2.04, 95% CI: 1.48-2.83, p < 0.01), while age ≥ 50 (aOR = 0.56, 95% CI: 0.32-0.98, 32 p = 0.04), condom use at last encounter (OR: 0.49, 95%CI: 0.33-0.73, p < 0.001), and not being on ART (aOR = 0.09, 95% CI: 0.06-0.13, p < 0.01) were associated with reduced odds of HIVDR. Conclusions: HIVDR was high among the participants. There is a need to address HIVDR and enhance the mechanisms already in place. This study introduces more information that would help in developing targeted interventions to prevent HIVDR and improve patient outcomes.

Patients and healthcare workers' preferences for using smart lockers in accessing and dispensing chronic disease medication in Nigeria: Findings from a descriptive cross-sectional study

The use of smart locker technology has been beneficial for patients with chronic diseases who require regular medication and face challenges accessing healthcare facilities due to distance, time, or mobility issues. This study aimed to assess preferences for utilizing Smart Lockers in accessing and dispensing chronic disease medication among healthcare workers (HCWs) and patients in Nigeria. A descriptive cross-sectional survey was conducted between November 8th and December 4th, 2021, across secondary healthcare facilities in five states of Adamawa, Akwa Ibom, Cross River, Benue, and Niger. Among 1,133 participants included in the analysis, 405 were HCWs and 728 were patients with chronic illnesses. Descriptive statistics, including frequencies and percentages, were used to summarize the data, while chi-square tests were employed to assess significant differences between healthcare workers (HCWs) and patients. Results indicated a strong preference among both HCWs and patients for one-on-one counseling as the preferred method for orientating patients on using Smart Lockers, with 53.8% of HCWs and 58.1% of patients expressing this preference (p = 0.25). Additionally, there was a shared preference for hospitals or clinics as secure locations for Smart Lockers, with 68.9% of HCWs and 71.6% of patients preferring this option (p < 0.05). The majority of participants favored receiving notification of drug delivery via phone call, with 49.1% of HCWs and 48.8% of patients expressing this preference (p = 0.63). There was a significant difference in preferences for access hours, the majority (HCWs: 65.4% and patients: 52.6%) favored 24-hour access (p < 0.05). Participants identified patients with HIV within the age range of 18-40 as the most suitable population to benefit from using Smart Lockers for medication dispensing. These findings offer insights into healthcare policies aimed at enhancing medication access and adherence among patients with chronic diseases in Nigeria. The development of models for using smart lockers to dispense chronic disease medications to chronically ill persons in Nigeria and other populations is recommended.

Patients' Preferences for Antiretroviral Therapy Service in Northwest Ethiopia: A Discrete Choice Experiment

Objective. We aim to evaluate patients' preferences for antiretroviral therapy (ART) to enhance shared decision making in clinical practice in Northwest Ethiopia. Methods. A discrete choice experiment approach was used among adult patients from 36 randomly selected public health facilities from February 6, 2023, to March 29, 2023. A literature review, qualitative work, ranking and rating surveys, and expert consultation were used to identify the attributes. Location, provider, frequency of visit, appointment modality, refill time, and cost of visit were the 6 ART service features chosen. Participants were given the option of choosing between 2 hypothetical differentiated ART delivery models. Mixed logit and latent class analysis were used. Results: Four hundred fifty-six patients completed the choice task. Respondents preferred to receive ART refills alone at health facilities by health care workers without having to have frequent visits and with reduced cost of visit. Overall, the participants valued the cost of the visit the most while they valued the timing of ART refill the least. Participants were willing to pay only for the attributes of frequency of visit and medication refill time. The latent class model with 3 classes provided the best model fit. Location, cost, and frequency were the most important attributes in class 1, class 2, and class 3, respectively. Income and marital status significantly predicted class membership. Conclusions. Respondents preferred to receive refills at health facilities, less frequent visits, individual appointments, service provision by health care workers, and reduced cost of visit. The cost attribute had the greatest impact on the choice of patients. Health care workers should consider the preferences of patients while providing ART services to meet patients' expectations and choices.

Highlights

A discrete choice experiment was used to elicit patient preferences.People living with HIV preferred receiving medication refills at health facilities, less frequent visits, individual appointments, service delivery by health care workers, and lower visit costs.Health care workers should consider the preferences of patients while providing ART service to meet their expectations and choices.Scaling up differentiated HIV treatment services is crucial for patient-centered care.

Differentiated service delivery models for antiretroviral treatment refills in Northern Nigeria: Experiences of people living with HIV and health care providers-A qualitative study

Differentiated service delivery (DSD) and multi-month dispensing (MMD) of antiretroviral therapy (ART) have improved treatment adherence and viral suppression among people living with HIV (PLHIV), and service delivery efficiency. We assessed the experiences of PLHIV and providers with DSD and MMD in Northern Nigeria. We conducted in-depth interviews (IDI) with 40 PLHIV and 6 focus group discussions (FGD) with 39 health care providers across 5 states, exploring their experiences with 6 DSD models. Qualitative data were analyzed using NVivo®1.6.1. Most PLHIV and providers found the models acceptable and expressed satisfaction with service delivery. The DSD model preference of PLHIV was influenced by convenience, stigma, trust, and cost of care. Both PLHIV and providers indicated improvements in adherence and viral suppression; they also raised concerns about quality of care within community-based models. PLHIV and provider experiences suggest that DSD and MMD have the potential to improve patient retention rates and service delivery efficiency.

HIV Care Preferences among Young People Living with HIV in Lesotho: A Secondary Data Analysis of the PEBRA Cluster Randomized Trial

Introduction

Sub-Saharan Africa is home to 89% of all young people living with HIV, a key population with specific challenges and needs. In-depth knowledge of service demands is needed to tailor and differentiate service delivery for this group. We evaluated HIV care preferences among young people living with HIV who were part of the PEBRA (Peer Educator Based Refill of ART) cluster-randomized trial.

Methods

The PEBRA trial evaluated a novel model of care at 20 health facilities in Lesotho, Southern Africa. In the PEBRA model, a peer educator regularly assessed participant preferences regarding antiretroviral therapy (ART) refill location, SMS notifications (for adherence, drug refill, viral load), and general care support options and delivered services accordingly over a 12-month period. We present these preferences and their changes over time.

Results

At enrolment, 41 of 123 (33.3%) chose ART refill outside the health facility, compared to 8 of 123 (6.5%) after 12 months. Among those selecting clinic-based ART refill, many preferred collecting ART during the peer educator led Saturday clinic club, 45 of 123 (36.5%) at the beginning and 55 of 123 (44.7%) at the end. SMS reminders for treatment adherence and ART refill visits were chosen by 51 of 123 (41.5%) at enrolment and 54 of 123 (44.7%) at the last assessment. Support by the peer educator was popular at the beginning (110 of 123 (89.4%)) and lower but still high at the end (85 of 123 (69.1%)). Thirteen of 123 (10.6%) participants chose support by the nurse, without the involvement of any peer educator, at the first and 21 of 123 (17.1%) at the last assessment.

Conclusion

Our longitudinal preference assessment among young people living with HIV in Lesotho showed a sustained interest in SMS notifications for adherence and refill visits as well as in additional support by a peer educator. ART refill outside the health facility was not as popular as expected; instead, medication pick-up at the facility, especially during Saturday clinic clubs, was favoured. The PEBRA trial was registered with clinicaltrials.gov (NCT03969030. Registered on 31 May 2019).

Understanding Uganda's early adoption of novel differentiated HIV treatment services: a qualitative exploration of drivers of policy uptake

BACKGROUND

Although differentiated service delivery (DSD) for HIV treatment was endorsed by the WHO in its landmark 2016 guidelines to lessen patients' need to frequently visit clinics and hence to reduce unnecessary burdens on health systems, uptake has been uneven globally. This paper is prompted by the HIV Policy Lab's annual report of 2022 which reveals substantial variations in programmatic uptake of differentiated HIV treatment services across the globe. We use Uganda as a case study of an 'early adopter' to explore the drivers of programmatic uptake of novel differentiated HIV treatment services.

METHODS

We conducted a qualitative case-study in Uganda. In-depth interviews were held with national-level HIV program managers (n = 18), district health team members (n = 24), HIV clinic managers (n = 36) and five focus groups with recipients of HIV care (60 participants) supplemented with documentary reviews. Our thematic analysis of the qualitative data was guided by the Consolidated Framework for Implementation Research (CFIR)'s five domains (inner context, outer setting, individuals, process of implementation).

RESULTS

Our analysis reveals that drivers of Uganda's 'early adoption' of DSD include: having a decades-old HIV treatment intervention implementation history; receiving substantial external donor support in policy uptake; the imperatives of having a high HIV burden; accelerated uptake of select DSD models owing to Covid-19 'lockdown' restrictions; and Uganda's participation in clinical trials underpinning WHO guidance on DSD. The identified processes of implementation entailed policy adoption of DSD (such as the role of local Technical Working Groups in domesticating global guidelines, disseminating national DSD implementation guidelines) and implementation strategies (high-level health ministry buy-in, protracted patient engagement to enhance model uptake, devising metrics for measuring DSD uptake progress) for promoting programmatic adoption.

CONCLUSION

Our analysis suggests early adoption derives from Uganda's decades-old HIV intervention implementation experience, the imperative of having a high HIV burden which prompted innovations in HIV treatment delivery as well as outer context factors such as receiving substantial external assistance in policy uptake. Our case study of Uganda offers implementation research lessons on pragmatic strategies for promoting programmatic uptake of differentiated treatment HIV services in other countries with a high HIV burden.

Uptake of community antiretroviral group delivery models for persons living with HIV in Arua district, Uganda: A parallel convergent mixed methods study

Community antiretroviral groups (CAGs) is one of the innovative and efficient differentiated service delivery models (DSDM) for reaching persons needing human immunodeficiency virus (HIV) treatment in the community. Since DSDM adoption in Uganda, evidence suggests better care outcomes for patients in DSDM compared to counterparts in routine health facility care. However, uptake of CAG models for eligible community groups of persons living with HIV (PLHIV) has been slow in Arua district, Uganda and stakeholders' perceptions regarding its implementation unexplored. The objective of the study was to determine the uptake, barriers and facilitators influencing CAG model implementation in Arua district, Uganda. We conducted a parallel convergent mixed-methods study from March 2020 to December 2020 at Adumi health centre IV and Kuluva hospital in Arua district. We enrolled and extracted data for every fifth virally suppressed participant on antiretroviral therapy (ART) at the two health facilities. Data were analysed using STATA 13.0. Uptake was determined as the proportion of eligible PLHIV that were enrolled into a group. We performed logistic regression to determine factors associated with uptake. We conducted one focus group discussion per facility among healthcare workers involved in the management of PLHIV. We also conducted 7 focus group discussions among PLHIV across the two facilities. Thematic analysis was used to describe the data. A total of 399 PLHIV were eligible for CAG, 61.6% were female, and 44.9% were on dolutegravir (DTG) based regimen. Uptake was 6.8%, 95% CI (4.7-9.7) and was found to be significantly associated with being divorced or separated in a marriage (OR; 0.14, 95%CI; 0.02-0.92, P = 0.014). Members picking drugs in turns, comforting and encouraging others to take the drugs, and health workers advising them to join and stay with other group members were perceived as facilitators to uptake of community antiretroviral group delivery model. Having few and distant eligible members in the local area to form a group, lack of transport among the member to pick the drugs when it's their turn, misunderstandings and lack of confidentiality amongst the members, and lack of partner disclosure were perceived as barriers to uptake of community antiretroviral group delivery model. Uptake of community antiretroviral group delivery model in Arua district is very low. There may be a need to support community antiretroviral group delivery models with income- generating activities, transport facilitation, closer community drug pick-up points and improved partner disclosure support mechanisms among married group members.

Uptake of appointment spacing model of care and associated factors among stable adult HIV clients on antiretroviral treatment Northwest Ethiopia

INTRODUCTION

Ethiopia launched an Appointment Spacing Model in 2017, which involved a six-month clinical visit and medication refill cycle. This study aimed to assess the uptake of the Appointment Spacing Model of care and associated factors among stable adult HIV clients on ART in Ethiopia.

METHODS

A cross-sectional study was conducted from October 3 to November 30, 2020 among 415 stable adult ART clients. EpiData version 4.2 was used for data entry and SPSS version 25 was used for cleaning and analysis. A multivariable logistic regression model was fitted to identify associated factors, with CI at 95% with AOR being reported to show the strength of association.

RESULTS

The uptake of the appointment spacing model was 50.1%. Residence [AOR: 2.33 (95% CI: 1.27, 4.26)], monthly income [AOR: 2.65 (95% CI: 1.13, 6.24)], social support [AOR: 2.21 (95% CI: 1.03, 4.71)], duration on ART [AOR: 2.41 (95% CI: 1.48, 3.92)], baseline regimen change [AOR: 2.20 (95% CI: 1.02, 4.78)], viral load [AOR: 2.80 (95% CI: 1.06, 7.35)], and alcohol abstinence [AOR: 2.02 (95% CI: 1.21, 3.37)] were statistically significant.

CONCLUSIONS

The uptake of the ASM was low. Behavioral change communication, engaging income-generating activities, and facility-level service providers' training may improve the uptake.

Availability and experiences of differentiated antiretroviral therapy delivery at HIV care facilities in rural Zimbabwe: a mixed-method study

INTRODUCTION

Zimbabwe adopted differentiated HIV care policies in 2015 to promote client-centred care and relieve strain on health facilities. We examined the availability, experiences and perceptions of differentiated antiretroviral therapy (ART) delivery in rural Zimbabwe following the policy adoption.

METHODS

We undertook a cross-sectional mixed methods study in all the 26 facilities providing HIV care in a rural district in Zimbabwe. We collected quantitative data about ART delivery and visit durations from 31 healthcare providers and a purposive stratified sample of 378 clients obtaining ART either through routine care or differentiated ART delivery models. We performed 26 semi-structured interviews among healthcare providers and seven focus group discussions (FGDs) among clients to elicit their perceptions and experiences of ART delivery. Data were collected in 2019, with one follow-up FGD in 2021. We analysed the transcripts thematically, with inductive coding, to identify emerging themes.

RESULTS

Twenty facilities (77%) offered at least one differentiated ART delivery models, including community ART refill groups (CARGs; 13 facilities, 50%), fast-track refill (8, 31%), family refill (6, 23%) or club refill (1, 4%). Thirteen facilities (50%) offered only one model. The median visit duration was 28 minutes (interquartile range [IQR]: 16-62). Participants in fast-track had the shortest visit durations (18 minutes, IQR: 11-24). Confidentiality and disclosure of HIV status, travelling long distances, travel costs and waiting times were the main issues influencing clients' views on differentiated ART delivery. Fast-track refill was perceived as the preferred model of clients for its limited involuntary disclosure and efficiency. In contrast, group- and community-based refill models reduced travel costs but were felt to be associated with involuntary disclosure of HIV status, which could discourage clients. Healthcare providers also experienced an additional workload when offering facility-based group models, such as CARGs.

CONCLUSIONS

Differentiated ART delivery models were widely available in this rural setting, but most facilities did not offer a choice of models to address clients' diverse preferences. A minority offered fast-track refills, although this model was often mentioned as desirable. Confidentiality, travel expenses and client waiting times are key elements to consider when planning and rolling out differentiated HIV care.

Patient experiences and preferences for antiretroviral therapy service provision: implications for differentiated service delivery in Northwest Ethiopia

Background

Understanding the experiences, needs, preferences, and behaviors of people living with HIV (PLHIV) are critical to tailor HIV treatment. However, there is limited empirical evidence in Ethiopia on the views of PLHIV regarding their experiences with current antiretroviral therapy (ART) services and preferred models of HIV treatment. Hence, this study aimed to explore the patients’ experiences of taking medications and preferences for ART service provision in Northwest Ethiopia.

Methods

A phenomenological study design was employed. In this study, stable and 18 years old and above PLHIVs, who had been using ART service at four public hospitals and two health centers in East Gojjam, West Gojjam and Awi zones, and Bahir Dar city administration of Amhara National Regional State, Northwest Ethiopia, were purposively selected. Fifteen in-depth interviews were conducted from July 2021 to September 2021 to collect data. ATLAS.ti version 9 software was used for coding translated transcripts. A thematic analysis approach was employed.

Findings

Participants in this study had reported positive and negative experiences in receiving ART services and also varied preferences toward ART service features. The study identified five themes on experiences for ART service and 15 attributes of ART service characteristics. The identified themes were stigma, time, availability of drugs and providers, costs for clinic visits, and provider-patient interaction. The fifteen attributes were buddy system, ART refill (individualized or group), ART packaging and labeling, drug formulation and administration, ART room labeling, distance, location of service, preferences on involvement in treatment decision-making, the person providing ART refills, provider’s attitude, spatial arrangement of ART room, time of health facility operation, time spent at clinics, and total cost of the visit.

Conclusions

The results raise awareness for the positive and negative experiences of patients informing us about barriers and supporting factors in ART service provision. They open up the potential for HIV treatment service improvement. The preferences of PLHIVs toward ART service delivery features were heterogeneous. Policy and program efforts should tailor ART services that suit patients’ needs and priorities in Ethiopia. Future research should further assess the reasons for patients’ distrust of the community ART delivery models.

eHealth supported multi-months dispensing of antiretroviral therapy: a mixed-methods preference assessment in rural Lesotho

BACKGROUND

Multi-month dispensing (MMD) of antiretroviral therapy (ART) represents one approach of differentiated service delivery (DSD) aiming to improve quality and cost-effectiveness for HIV services in resource-limited settings. However, reduction in clinic visits for people living with HIV (PLWH) should go along with out-of-clinic care tailored to PLWH`s preferences and comorbidities to maintain quality of care. eHealth supported MMD offers a potential solution.

METHODS

Between October 2019 and January 2020 we assessed preferences on an eHealth supported MMD package among adult PLWH attending routine ART care at a rural clinic in Lesotho using a mixed-methods approach. Participants reported their preferences among different refill and eHealth options. They were invited to test automated text messages (SMS) informing about their viral load results, an automated tuberculosis symptoms screening call and telemedical support by an expert nurse. Telemedical service comprised a call-back option if participants required any additional support and adherence counselling for closer follow-up of participants with unsuppressed viral loads. After 6 weeks, participants were followed-up to assess perception of the chosen eHealth support using a qualitative approach.

RESULTS

Among 112 participants (median age = 43 years; 74% female), 83/112 (75%) preferred MMD for 6-12 months (median = 9 months, IQR = [5, 12]). Neither sex, age, employment, costs and time for travel to clinic, nor the duration of taking ART correlated with the MMD preference. All 17 participants attending routine viral load measurement wished to receive the result via SMS. Fifteen (19.2%) participants requested a telemedical nurse call-back during the study period. All participants with recent unsuppressed viral load (N = 13) requested telemedical adherence counselling for closer follow-up. Among 78 participants followed-up, 76 (97%) would appreciate having the call-back option in future. Seventy-five participants (67%) received and evaluated the automated symptomatic tuberculosis screening call, overall 71 (95%) appreciated it.

CONCLUSIONS

The great majority of PLWH in this study preferred 6-12 months MMD and appreciated the additional eHealth support, including viral load results via SMS, telemedical nurse consultations and automated tuberculosis symptom screening calls. eHealth supported MMD packages appear to be a promising approach for DSD models and should be assessed for clinical endpoints and cost-effectiveness in larger studies.

Differentiated service delivery models among PLHIV in Akwa Ibom and Cross River States, Nigeria during the COVID-19 pandemic: descriptive analysis of programmatic data

Introduction

The rapid increase in the number of people living with HIV (PLHIV) on antiretroviral therapy (ART) in Akwa Ibom and Cross River states in Nigeria led to overcrowding at clinics. Patients were devolved to receive ART refills through five differentiated service delivery (DSD) models: fast‐track (FT), adolescent refill clubs (ARCs), community pharmacy ART refill programs (CPARPs), community ART refill clubs (CARCs) and community ART refill groups (CARGs) designed to meet the needs of different groups of PLHIV. In the context of COVID‐19‐related travel restrictions, out‐of‐facility models offered critical mechanisms for continuity of treatment. We compared retention and viral suppression among those devolved to DSD with those who continued standard care at facilities.

Methods

A retrospective cohort study was conducted among patients devolved to DSD from January 2018 to December 2020. Bivariate analyses were conducted to assess differences in retention and viral suppression by socio‐demographic characteristics. Kaplan–Meier assessed retention at 3, 6, 9 and 12 months. Differences in proportions were compared using the chi‐square test; a p‐value of <0.05 was considered significant.

Results

A total of 40,800 PLHIV from 84 facilities received ART through the five models: CARC (53%), FT (19.1%), ARC (12.1%), CPARP (10.4%) and CARG (5.4%). Retention rates at 6 months exceeded 96% for all models compared to 94% among those continuing standard care. Among those using DSD, retention rate at 12 months was higher among adults than children (97.8% vs. 96.7%, p = 0.04). No significant sex differences in retention rates were found among those enrolled in DSD. Viral suppression rates among PLHIV served through DSD were significantly higher among adults than children (95.4% vs. 89.2%; p <0.01). Among adults, 95.4% enrolled in DSD were virally suppressed compared to 91.8% of those in standard care (p <0.01). For children, 89.2% enrolled in DSD were virally suppressed compared to 83.2% in standard care (p <0.01).

Conclusions

PLHIV receiving ART through DSD models had retention but higher viral suppression rates compared to those receiving standard care. Expanding DSD during COVID‐19 has helped ensure uninterrupted access to ART in Nigeria. Further scale‐up is warranted to decongest facilities and improve clinical outcomes.

Patients' preferences for antiretroviral therapy service provision: a systematic review

Background

Achieving global targets of adherence to treatment, retention in care, and treatment success remains a challenge. Health system investment to make antiretroviral therapy services more responsive to patients’ needs and values could address these impediments. Appropriate resource allocation to implement differentiated HIV treatment services demands research evidence. This study aimed to provide an overview of the patients’ preferences for antiretroviral therapy service delivery features.

Methods

Electronic databases (PubMed, Web of Science, Embase, and CINAHL) and search engines (Google and Google Scholar) were searched. This review has followed a convergent segregated approach to synthesis and integration. Data from the included studies were systematically extracted, tabulated, and summarised in a narrative review. Studies that analysed preferences for antiretroviral therapy regardless of the method used and published in the English language in any year across the world and HIV positive clients who were 15 years and above on 4th February 2021 were included for this review. The quality of the included studies was assessed using the mixed methods appraisal tool. A thematic synthesis of the data from the findings section of the main body of the qualitative study was undertaken. ATLAS.ti software version 7 was used for qualitative synthesis.

Results

From the 1054 retrieved studies, only 23 studies (16 quantitative, three qualitative, and four mixed-methods) fulfilled the inclusion criteria. The median number of attributes used in all included quantitative studies was 6 (Inter Quartile Range 3). In this review, no study has fulfilled the respective criteria in the methodological quality assessment. In the quantitative synthesis, the majority of participants more valued the outcome, whereas, in the qualitative synthesis, participants preferred more the structure aspect of antiretroviral therapy service. The thematic analysis produced 17 themes, of which ten themes were related to structure, three to process, and four to outcome dimension of Donabedian’s quality of care model. The findings from individual quantitative and qualitative syntheses complement each other.

Conclusions

In this review, participants’ value for antiretroviral therapy service characteristics varied across included studies. Priorities and values of people living with HIV should be incorporated in the policy, practice, research, and development efforts to improve the quality of antiretroviral therapy service hence avoid poor patient outcomes.

A mixed-methods evaluation of the uptake of novel differentiated ART delivery models in a national sample of health facilities in Uganda

Introduction

Since 2017, Uganda has been implementing five differentiated antiretroviral therapy (ART) delivery models to improve the quality of HIV care and to achieve health-system efficiencies. Community-based models include Community Client-Led ART Delivery and Community Drug Distribution Points. Facility-based models include Fast Track Drug Refill, Facility Based Group and Facility Based Individual Management. We set out to assess the extent of uptake of these ART delivery models and to describe barriers to uptake of either facility-based or community-based models.

Methods

Between December 2019 and February 2020, we conducted a mixed-methods study entailing a cross-sectional health facility survey (n = 116) and in-depth interviews (n = 16) with ART clinic managers in ten case-study facilities as well as six focus group discussions (56 participants) with patients enrolled in differentiated ART models. Facilities were selected based on the 10 geographic sub-regions of Uganda. Statistical analyses were performed in STATA (v13) while qualitative data were analysed by thematic approach.

Results

Most facilities 63 (57%) commenced implementation of differentiated ART delivery in 2018. Fast Track Drug Delivery was the most common facility-based model (implemented in 100 or 86% of health facilities). Community Client-Led ART Delivery was the most popular community model (63/116 or 54%). Community Drug Distribution Points had the lowest uptake with only 33 (24.88%) facilities implementing them. By ownership-type, for-profit facilities reported the lowest uptake of differentiated ART models. Barriers to enrolment in community-based models include HIV-related stigma and low enrolment of adult males in community models.

Conclusion

To the best of our knowledge this is the first study reporting national coverage of differentiated ART delivery models in Uganda. Overall, there has been a higher uptake of facility-based models. Interventions for enhancing the uptake of differentiated ART models in for-profit facilities are recommended.

Dispensing antiretrovirals during Covid-19 lockdown: re-discovering community-based ART delivery models in Uganda

BACKGROUND

The notion of health-system resilience has received little empirical attention in the current literature on the Covid-19 response. We set out to explore health-system resilience at the sub-national level in Uganda with regard to strategies for dispensing antiretrovirals during Covid-19 lockdown.

METHODS

We conducted a qualitative case-study of eight districts purposively selected from Eastern and Western Uganda. Between June and September 2020, we conducted qualitative interviews with district health team leaders (n = 9), ART clinic managers (n = 36), representatives of PEPFAR implementing organizations (n = 6).In addition, six focus group discussions were held with recipients of HIV care (48 participants). Qualitative data were analyzed using thematic approach.

RESULTS

Five broad strategies for distributing antiretrovirals during 'lockdown' emerged in our analysis: accelerating home-based delivery of antiretrovirals,; extending multi-month dispensing from three to six months for stable patients; leveraging the Community Drug Distribution Points (CDDPs) model for ART refill pick-ups at outreach sites in the community; increasing reliance on health information systems, including geospatial technologies, to support ART refill distribution in unmapped rural settings. District health teams reported leveraging Covid-19 outbreak response funding to deliver ART refills to homesteads in rural communities.

CONCLUSION

While Covid-19 'lockdown' restrictions undoubtedly impeded access to facility-based HIV services, they revived interest by providers and demand by patients for community-based ART delivery models in case-study districts in Uganda.

Differentiated Service Delivery Models for HIV Treatment in Malawi, South Africa, and Zambia: A Landscape Analysis

INTRODUCTION

Many countries in Africa are scaling up differentiated service delivery (DSD) models for HIV treatment, but most existing data systems do not describe the models in use. We surveyed organizations that were supporting DSD models in 2019 in Malawi, South Africa, and Zambia to describe the diversity of DSD models being implemented at that time.

METHODS

We interviewed DSD model implementing organizations for descriptive information about each of the organization's models of care. We described the key characteristics of each model, including population of patients served, location of service delivery, frequency of interactions with patients, duration of dispensing, and cadre(s) of provider involved. To facilitate analysis, we refer to 1 organization supporting 1 model of care as an "organization-model."

RESULTS

The 34 respondents (8 in Malawi, 16 in South Africa, 10 in Zambia) interviewed described a total of 110 organization-models, which included 19 facility-based individual models, 21 out-of-facility-based individual models, 14 health care worker-led groups, and 3 client-led groups; jointly, these encompassed 12 specific service delivery strategies, such as multimonth dispensing, adherence clubs, home delivery, and changes to facility hours. Over two-thirds (n=78) of the organization-models were limited to clinically stable patients. Almost all organization-models (n=96) continued to provide clinical care at established health care facilities; medication pickup took place at facilities, external pickup points, and adherence clubs. Required numbers of provider interactions per year varied widely, from 2 to 12. Dispensing intervals were typically 3 or 6 months in Malawi and Zambia and 2 months in South Africa. Individual models relied more on clinical staff, while group models made greater use of lay personnel.

CONCLUSIONS

As of 2019, there was a large variety of differentiated service models being offered for HIV treatment in Malawi, South Africa, and Zambia, serving diverse patient populations.

Scientific HIV research in Africa and the Middle East: a socio-economic demographic analysis

Background: In Africa, HIV/AIDS research is concentrated in certain countries, particularly South Africa. This distribution may not accurately reflect the disease prevalence or the true research efforts of countries.Objectives: To identify HIV/AIDS research productivity of countries in Africa and the Middle East, in absolute terms and adjusted for people living with HIV, population size and economic development.Methods: We identified all the articles and reviews on HIV and AIDS in the Web of Science Core Collection in which African or Middle Eastern countries had participated. After determining the number of documents produced by each country, we adjusted the findings for the number of people living with HIV, number of inhabitants, gross domestic product and gross national income per capita.Results: African and Middle Eastern countries participated in 21.52% (n = 14 808) of all 68 808 documents analysed. East and Southern Africa produced 17.8% of all documents (n = 12 249), West and Central Africa accounted for only 3.34% (n = 2300), and the Middle East and North Africa, 1.18% (n = 814). South Africa produced 40.94% (n = 6 063) of all publications. Only two other African countries - Uganda (12.97%; n = 1 921) and Kenya (10.71%; n = 1 586) - produced more than 10% of these publications. The indices used for adjusting research productivity revealed the effort and contribution of other countries.Conclusion: Our study confirmed the leading role of South Africa in driving HIV/AIDS research, but also highlighted the contribution of countries such as Uganda, Malawi, Botswana, Zimbabwe and Mozambique.

Optimizing Differentiated HIV Treatment Models in Urban Zimbabwe: Assessing Patient Preferences Using a Discrete Choice Experiment

Differentiated service delivery holds great promise for streamlining the delivery of health services for HIV. This study used a discrete choice experiment to assess preferences for differentiated HIV treatment delivery model characteristics among 500 virally suppressed adults on antiretroviral therapy in Harare, Zimbabwe. Treatment model characteristics included location, consultation type, healthcare worker cadre, operation times, visit frequency and duration, and cost. A mixed effects logit model was used for parameter estimates to identify potential preference heterogeneity among participants, and interaction effects were estimated for sex and age as potential sources of divergence in preferences. Results indicated that participants preferred health facility-based services, less frequent visits, individual consultations, shorter waiting times, lower cost and, delivered by respectful and understanding healthcare workers. Some preference heterogeneity was found, particularly for location of service delivery and group vs. individual models; however, this was not fully explained by sex and age characteristics of participants. In urban areas, facility-based models, such as the Fast Track model requiring less frequent clinic visits, are likely to better align with patient preferences than some of the other community-based or group models that have been implemented. As Zimbabwe scales up differentiated treatment models for stable patients, a clear understanding of patient preferences can help in designing services that will ensure optimal utilization and improve the efficiency of service delivery.

Exploring Relative Preferences for HIV Service Features Using Discrete Choice Experiments: a Synthetic Review

PURPOSE OF REVIEW

Aligning HIV treatment services with patient preferences can promote long-term engagement. A rising number of studies solicit such preferences using discrete choice experiments, but have not been systematically reviewed to seek generalizable insights. Using a systematic search, we identified eleven choice experiments evaluating preferences for HIV treatment services published between 2004 and 2020.

RECENT FINDINGS

Across settings, the strongest preference was for nice, patient-centered providers, for which participants were willing to trade considerable amounts of time, money, and travel distance. In low- and middle-income countries, participants also preferred collecting antiretroviral therapy (ART) less frequently than 1 monthly, but showed no strong preference for 3-compared with 6-month refill frequency. Facility waiting times and travel distances were also important but were frequently outranked by stronger preferences. Health facility-based services were preferred to community- or home-based services, but this preference varied by setting. In high-income countries, the availability of unscheduled appointments was highly valued. Stigma was rarely explored and costs were a ubiquitous driver of preferences. While present improvement efforts have focused on designs to enhance access (reduced waiting time, travel distance, and ART refill frequency), few initiatives focus on the patient-provider interaction, which represents a promising critical area for inquiry and investment. If HIV programs hope to truly deliver patient-centered care, they will need to incorporate patient preferences into service delivery strategies. Discrete choice experiments can not only inform such strategies but also contribute to prioritization efforts for policy-making decisions.
