ABSTRACT

Sexual and gender minority (SGM) adults experience poor health outcomes, in part due to frequent avoidance of necessary health care. Little is known, however, about factors contributing to patterns of health care utilization in this population. Using national data from the All of Us Research Program, this study evaluated the prevalence of care avoidance due to patient-clinician identity discordance (PCID) and its association with health care discrimination among SGM adults. Sexual minority (20.0% vs 9.4%; adjusted rate ratio [aRR] = 1.58; 95% CI, 1.49-1.67, P <0.001) and gender minority adults (34.4% vs 10.3%; aRR = 2.00; 95% CI, 1.79-2.21, P <0.001) were significantly more likely than their non-SGM counterparts to report care avoidance due to PCID. Exposure to health care discrimination was also more prevalent in this population and was dose-dependently associated with significantly higher rates of PCID-based care avoidance. Study findings highlight the importance of diversifying the health care workforce, expanding SGM-related clinical training, and preventing health care discrimination against SGM patients.

ABSTRACT

PURPOSE: Information about social determinants of health (SDOH) is essential for primary care clinicians in the delivery of equitable, comprehensive care, as well as for program planning and resource allocation. SDOH are rarely captured consistently in clinical settings, however. Artificial intelligence (AI) could potentially fill these data gaps, but it needs to be designed collaboratively and thoughtfully. We report on a codesign process with primary care clinicians to understand how an AI tool could be developed, implemented, and used in practice. METHODS: We conducted semistructured, 50-minute workshops with a large urban family health team in Toronto, Ontario, Canada asking their feedback on a proposed AI-based tool used to derive patient SDOH from electronic health record data. An inductive thematic analysis was used to describe participants' perspectives regarding the implementation and use of the proposed tool. RESULTS: Fifteen participants contributed across 4 workshops. Most patient SDOH information was not available or was difficult to find in their electronic health record. Discussions focused on 3 areas related to the implementation and use of an AI tool to derive social data: people, process, and technology. Participants recommended starting with 1 or 2 social determinants (income and housing were suggested as priorities) and emphasized the need for adequate resources, staff, and training materials. They noted many challenges, including how to discuss the use of AI with patients and how to confirm their social needs identified by the AI tool. CONCLUSIONS: Our codesign experience provides guidance from end users on the appropriate and meaningful design and implementation of an AI-based tool for social data in primary care.

ABSTRACT

BACKGROUND: Limited research has been conducted on the forms, manifestations and effects of intersectional stigma among young HIV-positive men who have sex with men (MSM) and transgender women (TGW) in Zambia. In this study, we aimed to address this gap by elucidating the experiences of these in a small group of young, HIV + MSM and TGW in Zambia. METHODS: We applied a mixed-methods design. Data were collected from January 2022 to May 2022. Qualitative data were collected using in-depth interviews while quantitative data were collected using a questionnaire. Qualitative transcripts were coded using thematic analysis while paper-based questionnaire data were entered into Kobo Connect. Descriptive statistics, using chi-squared tests were calculated using Excel. In this paper, we provide a descriptive profile of the sample and then focus on the qualitative findings on intersectional stigma, depression, and contemplation of suicide. RESULTS: We recruited 56 participants from three sites: Lusaka, Chipata, and Solwezi districts. Participants' mean age was 23 years. The study found that 36% of all participants had moderate to significant symptoms of depression, 7% had major depression, 30% had moderate signs of anxiety, 11% had high signs of anxiety, 4% had very high signs of anxiety and 36% had contemplated suicide at least once. A greater proportion of TGW had moderate to significant symptoms of depression (40%) or major depression (10%) compared to MSM, at 33% and 6%, respectively (X2 = 0.65; p = 0.42). Similarly, more TGW (55%) had contemplated suicide than MSM peers (36%, X2=1.87; p = 0.17). In the qualitative data, four emergent themes about the forms, manifestations, and effects of intersectional stigma were (1) HIV, sexual orientation, and gender identity disclosure; (2) Dual identity; (3) Challenges of finding and maintaining sexual partners; (4) Coping and resilience. Overall, having to hide both one's sexuality and HIV status had a compounding effect and was described as living "a private lie." CONCLUSION: Effectively addressing stigmas and poor mental health outcomes among young HIV-positive MSM and TGW will require adopting a socio-ecological approach that focuses on structural interventions, more trauma-informed and identity-supportive care for young people with HIV, as well as strengthening of authentic community-informed public health efforts.

ABSTRACT

BACKGROUND: In older patients, esophageal squamous cell carcinoma (ESCC) is difficult to treat using standard therapies, including surgery and cisplatin-based chemoradiotherapy. Paclitaxel (PTX) has radiosensitizing activity. We conducted a phase I trial of PTX combined with radiotherapy to establish a standard therapy for locally advanced ESCC in older patients. METHODS: Enrollment was conducted at six centers in Japan from April 2016 to September 2019. The participants were aged ≥ 70 years, had locally advanced ESCC, and were intolerant to surgery or unwilling. A fixed 60-Gy radiation dose was administered in 30 fractions. PTX dosing levels started at 30 mg/m2 weekly for 6 weeks. Depending on the number of DLTs, the dose was set to be increased by 10 mg/m2 or switched to biweekly. A geriatric assessment was performed before treatment using the Geriatric-8 screening tool. The primary endpoint was dose-limiting toxicity (DLT). RESULTS: We enrolled 24 patients (6 per group); DLT was observed in one (grade 4 hypokalemia), one (grade 3 aspiration), two (grade 3 radiodermatitis, grade 3 esophageal hemorrhage), and two (grade 3 anorexia, grade 5 pneumonitis) patients in the weekly PTX 30, 40, 50, and 60 mg/m2 groups, respectively. All adverse events, except death in the 60 mg/m2 group, showed reversible improvement, and the safety profile was considered acceptable. The 2-year survival and complete response rates were 40.0% and 54.2%, respectively. There was a significant difference in survival between favorable and unfavorable Geriatric-8 scores. CONCLUSIONS: The recommended PTX dose with concomitant radiation was determined to be 50 mg/m2 weekly. Phase II trials at this dose are underway.

ABSTRACT

Access to healthy foods, especially for those who are living with diabetes and hypertension, is crucial in managing these chronic diseases. This study evaluates the implementation of a food pharmacy and food prescription program at a safety-net hospital that serves vulnerable populations. Patients who screen as food insecure using the USDA adult food security survey receive a referral from the physician to the food pharmacy program where a dietician reviews their dietary requirements based on their chronic disease and develops a diet plan. Patients then receive fresh produce, meats and other products every 2 weeks that meets their nutritional needs from the food pharmacy. Biometric data from the patient's most recent clinic visit at the time of enrollment was collected as the baseline measures including blood pressure, weight, and HbA1c (if diabetic). Additionally, biometric information was collected from the patient's medical records from regularly scheduled clinic visits at 6 month intervals. A total of 266 patients were enrolled in the program during the 13-month period that was studied (121 patients with 6-month data and 68 patients with 12-month data). The statistical analysis showed a significant improvement in diastolic blood pressure at 12 months and in weight at both the 6 months and 12 months timeframes when comparing to baseline biometrics.

ABSTRACT

BACKGROUND: Health and care research involving people who lack capacity to consent requires an alternative decision maker to decide whether they participate or not based on their 'presumed will'. However, this is often unknown. Advance research planning (ARP) is a process for people who anticipate periods of impaired capacity to prospectively express their preferences about research participation and identify who they wish to be involved in future decisions. This may help to extend individuals' autonomy by ensuring that proxy decisions are based on their actual wishes. This qualitative study aimed to explore stakeholders' views about the acceptability and feasibility of ARP and identify barriers and facilitators to its implementation in the UK. METHODS: We conducted semi-structured interviews with 27 researchers, practitioners, and members of the public who had participated in a preceding survey. Interviews were conducted remotely between April and November 2023. Data were analysed thematically. RESULTS: Participants were supportive of the concept of ARP, with differing amounts of support for the range of possible ARP activities depending on the context. Six main themes were identified: (1) Planting a seed - creating opportunities to initiate/engage with ARP; (2) A missing part of the puzzle - how preferences expressed through ARP could help inform decisions; (3) Finding the sweet spot - optimising the timing of ARP; (4) More than a piece of paper - finding the best mode for recording preferences; (5) Keeping the door open to future opportunities - minimising the risk of unintended consequences; and (6) Navigating with a compass - principles underpinning ARP to ensure safeguarding and help address inequalities. Participants also identified a number of implementation challenges, and proposed facilitative strategies that might overcome them which included embedding advance research planning in existing future planning processes and research-focused activities. CONCLUSIONS: This study provides a routemap to implementing ARP in the UK to enable people anticipating impaired capacity to express their preferences about research, thus ensuring greater opportunities for inclusion of this under-served group, and addressing the decisional burden experienced by some family members acting as proxies. Development of interventions and guidance to support ARP is needed, with a focus on ensuring accessibility.

ABSTRACT

BACKGROUND: Amyotrophic lateral sclerosis (ALS) is a progressive, fatal disease with largely unknown etiology. This study compares racial differences in clinical characteristics of ALS patients enrolled in the National ALS Registry (Registry). METHODS: Data from ALS patients who completed the Registry's online clinical survey during 2013-2022 were analyzed to determine characteristics such as site of onset, associated symptoms, time of symptom onset to diagnosis, and pharmacological and non-pharmacological interventions for White, Black, and other race patients. RESULTS: Surveys were completed by 4242 participants. Findings revealed that Black ALS patients were more likely to be diagnosed at a younger age, to have arm or hand initial site of onset, and to experience pneumonia than were White ALS patients. ALS patients of other races were more likely than White ALS patients to be diagnosed at a younger age and to experience twitching. The mean interval between the first sign of weakness and an ALS diagnosis for Black patients was almost 24 months, statistically greater than that of White (p = 0.0374; 16 months) and other race patients (p = 0.0518; 15.8 months). The mean interval between problems with speech until diagnosis was shorter for White patients (6.3 months) than for Black patients (17.7 months) and other race patients (14.8 months). CONCLUSIONS AND RELEVANCE: Registry data shows racial disparities still exist in the diagnosis and clinical characteristics of ALS patients. Increased recruitment of non-White ALS patients and better characterization of symptom onset between races might aid clinicians in diagnosing ALS sooner, leading to earlier therapeutic interventions.

ABSTRACT

An introduction to a novel habitat represents a challenge to plants because they likely would face new interactions and possibly different physical context. When plant populations arrive to a new region free from herbivores, we can expect an evolutionary change in their defense level, although this may be contingent on the type of defense, resistance or tolerance, and cost of defense. Here, we addressed questions on the evolution of tolerance to damage in non-native Spanish populations of Datura stramonium by means of two comparative greenhouse experiments. We found differences in seed production, specific leaf area, and biomass allocation to stems and roots between ranges. Compared to the Mexican native populations of this species, non-native populations produced less seeds despite damage and allocate more biomass to roots and less to stems, and had higher specific leaf area values. Plasticity to leaf damage was similar between populations and no difference in tolerance to damage between native and non-native populations was detected. Costs for tolerance were detected in both regions. Two plasticity traits of leaves were associated with tolerance and were similar between regions. These results suggest that tolerance remains beneficial to plants in the non-native region despite it incurs in fitness costs and that damage by herbivores is low in the non-native region. The study of the underlying traits of tolerance can improve our understanding on the evolution of tolerance in novel environments, free from plants' specialist herbivores.

ABSTRACT

BACKGROUND: Mobile Link is a mobile phone-based intervention to increase access to, and use of, health care services among female entertainment workers in Cambodia who face higher risks for specific diseases and gender-based violence. A multisite randomized controlled trial showed that Mobile Link connected female entertainment workers with outreach workers for information and escorted referrals after 6 months but did not lead to statistically significant improvements in HIV and sexually transmitted infection testing, contraceptive use, and condom use. OBJECTIVE: This study aims to conduct a 3-part economic evaluation of Mobile Link to understand its costs, value, and affordability. METHODS: We conducted cost, cost-effectiveness, and budget impact analyses of Mobile Link using cost and outcomes data from the Mobile Link trial and other sources. For the cost analysis, we estimated the total, per-person, and incremental costs of Mobile Link compared with usual care. Using probabilistic decision-analytic models, we estimated the 1-year cost-effectiveness of Mobile Link from payer and combined payer and patient perspectives by converting selected primary and secondary outcomes from the trial to disability-adjusted life years (DALYs) averted. Finally, we estimated the financial costs of scaling up Mobile Link's messaging and outreach services to 70% of female entertainment workers in 5 years. RESULTS: The incremental costs of Mobile Link were US $199 from a payer perspective and US $195 per person from a combined payer and patient perspective. With an average of 0.018 (95% predicted interval -0.088 to 0.126) DALYs averted, Mobile Link's cost-effectiveness was US $10,955 per DALY from a payer perspective (US $10,755 per DALY averted from a payer and patient perspective). The costs of Mobile Link would have to decrease by 85%, or its effectiveness would have to be 5.56 times higher, for the intervention to meet the upper limit of recommended cost-effectiveness thresholds in Cambodia (US $1671 per DALY averted). The 5-year cost of scaling Mobile Link to 34,790 female entertainment workers was estimated at US $1.64 million or US $46 per person per year. CONCLUSIONS: This study provided a comprehensive economic evaluation of Mobile Link. We found that Mobile Link is not likely to be cost-effective unless its costs decrease or its effectiveness increases. Scaling up Mobile Link to more female entertainment workers is estimated to cost less than the costs of the trial. Given the importance of linking female entertainment workers to essential services, future research should focus on enhancing the effectiveness of Mobile Link or developing new mobile health interventions for this population.

ABSTRACT

Upper respiratory tract infections (URTI) account for more than 80% of wheezing episodes in children with a high incidence of hospitalization in preschool age. Most children with symptoms of wheezing during an URTI are usually non-atopic. As the majority of wheezing episodes resulting from URTI are attributed to viral triggers, several studies have suggested the potential anti-inflammatory and antiviral properties of resveratrol. This study aims to identify the effect of resveratrol for pediatric non-atopic patients with recurrent wheezing triggered by URTIs. We conducted a prospective single-blind study to assess the effectiveness of a short course of nasal solutions incorporating resveratrol and carboxymethyl-ß-glucan, administered for 7 days at the onset of URTIs, compared to standard nasal lavage with 0.9% saline solution. A total of 19 patients entered the active group, 20 patients were assigned to the placebo group. The comparison of overall wheezing days (p < 0.001), mean wheezing days per month (p < 0.01), and wheezing episodes per patient (p < 0.001) in the two groups showed a significant reduction in the group receiving resveratrol compared with the placebo group, with less hospital access (p < 0.001) and oral corticosteroid administration (p < 0.01). Our findings seem to suggest that, in non-atopic children with recurrent wheezing secondary to URTIs, nasal resveratrol could be effective to prevent or reduce the occurrence of wheezing, when started from the onset of upper airway symptoms.

ABSTRACT

Fibroblast heterogeneity remains undefined in eosinophilic esophagitis (EoE), an allergic inflammatory disorder complicated by fibrosis. We utilized publicly available single-cell RNA sequencing data (GSE201153) of EoE esophageal biopsies to identify fibroblast sub-populations, related transcriptomes, disease status-specific pathways and cell-cell interactions. IL13-treated fibroblast cultures were used to model active disease. At least 2 fibroblast populations were identified, F_A and F_B. Several genes including ACTA2 were more enriched in F_A. F_B percentage was greater than F_A and epithelial-mesenchymal transition upregulated in F_B vs. F_A in active and remission EoE. Epithelial-mesenchymal transition was also upregulated in F_B in active vs. remission EoE and TNF-α signaling via NFKB was downregulated in F_A. IL-13 treatment upregulated ECM-related genes more profoundly in ACTA2- fibroblasts than ACTA2+ myofibroblasts. After proliferating epithelial cells, F_B and F_A contributed most to cell-cell communication networks. ECM-Receptor interaction strength was stronger than secreted or cell-cell contact signaling in active vs. remission EoE and significant ligand-receptor pairs were driven mostly by F_B. This unbiased analysis identifies at least 2 fibroblast sub-populations in EoE in vivo, distinguished in part by ACTA2. Fibroblasts play a critical role in cell-cell interactions in EoE, most profoundly via ECM-receptor signaling via the F_B sub-group.

ABSTRACT

There is consensus regarding the socio-political roots of the concept of race (and ethnicity) in the United States (US). However arbitrary, the US societal constructions of race have meant racial/ethnic minorities experience disproportionate health burdens. The present study examined the so-called "white health advantage" effect in a large sample of US respondents, comparing Latinos (non-White and White) with non-Latino Whites. This cross-sectional study used deidentified data from the Dynata Global COVID Symptoms map project, collected between July 7-14, 2020 (n = 135,075). A dichotomous health status variable was created with respondents answering yes/no to any COVID-19 symptoms (difficulty breathing, coughing, fatigue, fever, and loss of taste or smell). We included relevant predisposing (age, gender, number of children, race, ethnicity, marital status, and education) and enabling factors (housing conditions, income, employment status, business ownership, and number of cars owned - a proxy measure for wealth). Multivariate logistic regression models showed significant differences in health status (as measured by COVID-19 symptoms) when comparing Latinos (non-White, White) and non-Latino Whites. For instance, higher socioeconomic status had a protective effect only among non-Latino Whites. In turn, being married/living with a partner was only associated with COVID-19 symptoms among White Latinos, indicating that the apparent benefits of this "improving" socio-political location are somewhat limited. Our study found significant differences in COVID-19 symptoms when comparing Latinos (non-White, White) and non-Latino Whites. Our findings underscore the importance of further examining health outcomes by racial identities of US Latinos, which can help inform future health equity efforts.

ABSTRACT

Stressors associated with urban habitats have been linked to poor wildlife health but whether a general negative relationship between urbanization and animal health can be affirmed is unclear. We conducted a meta-analysis of avian literature to test whether health biomarkers differed on average between urban and non-urban environments, and whether there are systematic differences across species, biomarkers, life stages and species traits. Our dataset included 644 effect sizes derived from 112 articles published between 1989 and 2022, on 51 bird species. First, we showed that there was no clear impact of urbanization on health when we categorized the sampling locations as urban or non-urban. However, we did find a small negative effect of urbanization on health when this dichotomous variable was replaced by a quantitative variable representing the degree of urbanization at each location. Second, we showed that the effect of urbanization on avian health was dependent on the type of health biomarker measured as well as the individual life stage, with young individuals being more negatively affected. Our comprehensive analysis calls for future studies to disentangle specific urban-related drivers of health that might be obscured in categorical urban versus non-urban comparisons.

ABSTRACT

Human dermal exposure to chlorinated paraffins (CPs) has not been well documented. Therefore, hand wipes were collected from four occupational populations to analyze short-chain CPs (SCCPs) and medium-chain CPs (MCCPs) in order to estimate dermal uptake and oral ingestion via hand-to-mouth contact. The total CP levels (∑SCCPs and ∑MCCPs) in wipes ranged from 71.4 to 2310 µg/m2 in security guards, 37.6 to 333 µg/m2 in taxi drivers, 20.8 to 559 µg/m2 in office workers, and 20.9 to 932 µg/m2 in undergraduates, respectively. Security guards exhibited the highest levels of ∑SCCPs among four populations (p < 0.01). In undergraduates engaged in outdoor activities, C13 emerged as the most dominant SCCPs homologue group, followed by C12, C11, and C10. The levels of ∑SCCPs and ∑MCCPs in males in light haze pollution were significantly higher than that in heavy haze pollution (p < 0.05). The median estimated dermal absorption dose of SCCPs and MCCPs via hand was 22.2 and 104 ng (kg of bw)-1 day-1, respectively, approximately 1.5 times the oral ingestion [12.3 and 74.4 ng (kg of bw)-1 day-1], suggesting that hand contact is a significant exposure source to humans.

ABSTRACT

Background: Lifestyle plays an important role in shaping the gut microbiome. However, its contributions to the oral microbiome remains less clear, due to the confounding effects of geography and methodology in investigations of populations studied to date. Furthermore, while the oral microbiome seems to differ between foraging and industrialized populations, we lack insight into whether transitions to and away from agrarian lifestyles shape the oral microbiota. Given the growing interest in so-called 'vanishing microbiomes' potentially being a risk factor for increased disease prevalence in industrialized populations, it is important that we distinguish lifestyle from geography in the study of microbiomes across populations. Results: Here, we investigate salivary microbiomes of 63 Nepali individuals representing a spectrum of lifestyles: foraging, subsistence farming (individuals that transitioned from foraging to farming within the last 50 years), agriculturalists (individuals that have transitioned to farming for at least 300 years), and industrialists (expatriates that immigrated to the United States within the last 20 years). We characterize the role of lifestyle in microbial diversity, identify microbes that differ between lifestyles, and pinpoint specific lifestyle factors that may be contributing to differences in the microbiomes across populations. Contrary to prevailing views, when geography is controlled for, oral microbiome alpha diversity does not differ significantly across lifestyles. Microbiome composition, however, follows the gradient of lifestyles from foraging through agrarianism to industrialism, supporting the notion that lifestyle indeed plays a role in the oral microbiome. Relative abundances of several individual taxa, including Streptobacillus and an unclassified Porphyromonadaceae genus, also mirror lifestyle. Finally, we identify specific lifestyle factors associated with microbiome composition across the gradient of lifestyles, including smoking and grain source. Conclusion: Our findings demonstrate that by controlling for geography, we can isolate an important role for lifestyle in determining oral microbiome composition. In doing so, we highlight the potential contributions of several lifestyle factors, underlining the importance of carefully examining the oral microbiome across lifestyles to improve our understanding of global microbiomes.

ABSTRACT

INTRODUCTION: Since the onset of the Russian invasion on 24 February 2022, the health system in Ukraine has been placed under tremendous pressure, with damage to critical infrastructure, large losses of human resources, restricted mobility and significant supply chain interruptions. Based on a longstanding partnership between the Ukrainian Institute for Social Research after Oleksandr Yaremenko (UISR after O. Yaremenko) and the Institute for Global Public Health at the University of Manitoba, we explore the impact of the full-scale war on non-governmental organizations (NGOs, including charitable organizations) providing services for key population groups in Ukraine. METHODS: We conducted in-depth qualitative interviews with key representatives from NGOs working with key population groups (i.e., people living with HIV, sex workers, men who have sex with men, people who inject drugs and transgender people) throughout Ukraine. Members of the UISR after O. Yaremenko research team recruited participants from organizations working at national, regional and local levels. The research team members conducted 26 interviews (22 with women and four with men) between 15 May and 7 June 2023. Interviews were conducted virtually in Ukrainian and interpretively analysed to draw out key themes. RESULTS: Applying Roels et al.'s notion of "first responders", our findings explore how the full-scale war personally and organizationally impacted workers at Ukrainian NGOs. Despite the impacts to participants' physical and mental health, frontline workers continued to support HIV prevention and treatment while also responding to the need for humanitarian aid among their clients and the wider community. Furthermore, despite inadequate pay and compensation for their work, frontline workers assumed additional responsibilities, thereby exceeding their normal workload during the extraordinary conditions of war. CONCLUSIONS: NGOs play a vital role as responders, adapting their services to meet the emergent needs of communities during structural shocks, such as war. There is an urgent need to support NGOs with adequate resources for key population service delivery and to increase support for their important role in humanitarian aid.

ABSTRACT

INTRODUCTION: Globally, stark inequities exist in access to HIV treatment and prevention. The eastern European and central Asian region is experiencing the sharpest rise in new HIV acquisition and deaths in the world, with low rates of treatment and prevention services, especially for key and vulnerable populations who face a range of human rights-related barriers to HIV prevention and treatment. METHODS: An implementation learning evaluation approach was used to examine the implementation of the Breaking Down Barriers initiative targeting key and vulnerable populations in Ukraine. Between September 2022 and April 2023, researchers conducted 23 key informant interviews with individuals from the Ukrainian government, implementing organizations and human rights experts. Using a concurrent triangulation design, researchers and key informants, in a process of co-creation, sought to describe programme accomplishments, challenges and innovations in implementation, between 2021 and 2023, including periods before and after Russia's February 2022 full-scale invasion. RESULTS: Eight rights-based interventions related to HIV were identified in Global Fund programme documents and key informant interviews as making up the core of the Breaking Down Barriers initiative in Ukraine. These included programmes seeking to: eliminate stigma and discrimination; ensure the non-discriminatory provision of medical care; promote rights-based law enforcement practices; expand legal literacy ("know your rights"); increase access to justice; improve laws, regulations and policies; reduce gender discrimination, harmful gender norms and violence against women and girls; and mobilize communities for advocacy. These programmes received US$5.9 million in funding. Key informants reported that significant progress had been made addressing human rights barriers and scaling up interventions, both before and after Russia's invasion. Programme implementors adopted innovative approaches, including using paralegals, hotlines and other community-led interventions, to ensure that key and vulnerable populations, including displaced individuals, were able to access prevention and care. CONCLUSIONS: An implementation learning evaluation approach examining programmes addressing human rights barriers to HIV services, designed as a process of co-creation between researchers, programme implementors, government officials and human rights experts, can provide a robust assessment of programme outputs, outcomes and evidence of impact, despite a challenging operational environment.
