Equity in HIV/AIDS services requires optimization of mainstreaming sectors in Ethiopia.

BACKGROUND: Mainstreaming HIV and AIDS across sectors is crucial to close the disparities in service provision and coverage. However, evidence has shown that certain social groups are left behind in receiving HIV/AIDS services. The objective of this study was twofold: to understand the reasons behind the existing inequities and to explore challenges of equity in HIV/AIDS services in the Amhara region of Ethiopia. METHODS: Twenty-two adults (aged 26-57 years) from eighteen sectors that are mainstreaming HIV and AIDS were purposefully selected until the point of saturation and participated in a semi-structured in-depth interview conducted between January 20 and February 17, 2023. Interviewees were asked to describe their mainstreaming experiences in equitable HIV/AIDS services, reflect on the challenges and barriers that impede equitable service provision, or explain the reasons behind the existence of inequity in HIV/AIDS services. The interviews were audio recorded, transcribed, translated, and iteratively analysed, with early analysis informing subsequent interviews. An inductive-reflexive thematic analysis was conducted, whereby themes and subthemes were identified, and the relationships between subthemes and patterns were critically reviewed. RESULTS: The challenges to equitable HIV/AIDS service provision were grouped into eight thematic areas: (1) changing contexts that shifts public and government attention to emerging diseases, war and political instability, and poverty; (2) leadership-related, such as the lack of supervision and monitoring, not politicising HIV/AIDS (not providing political attention to HIV/AIDS) and weak intersectoral collaboration; (3) financial constraints due to a random budgeting and contract interruption with non-governmental organisations (NGOs); (4) lack of resources due to scarcity and unfair distribution; (5) inadequate skilled personnel due to inadequate numbers and lack of continuous professional and career development; (6) lack of equity-related evidence-based tools and guidelines; (7) inadequate understanding of equity due to lack of training and misunderstanding, and lack of access to equity-oriented tools and guidelines; and (8) cultural norms, values, and perceptions. CONCLUSIONS: This study identified critical challenges faced in the equitable HIV/AIDS services provision. To achieve equity in HIV/AIDS services, mainstreaming sectors need to invest in mechanisms to sustain services in emergency situations; identify effective leaders to maintain collaboration, monitoring, and evaluation; institutionalise responsive budgeting and establish alternative funds to maintain non-governmental organisations initiatives; provide continuous up-to-date training and create a common evidence-sharing platform; implement proper recruitment, education, and professional development of HIV/AIDS focal persons; and promote and practice culturally safe care. It is, therefore, essential to optimise sectors that are mainstreaming HIV/AIDS and incorporate equity considerations in their strategic plans and working guidelines.

Explaining inequity in knowledge, attitude, and services related to HIV/AIDS: a systematic review.

BACKGROUND: Equitable service provision and coverage are important responses to end the threat of the HIV/AIDS pandemic. Understanding inequity supports policies and programmes to deliver tailored interventions. There is continuous evidence generation on inequity in HIV/AIDS services. However, there was a lack of evidence on the global picture of inequity in behavioural and biomedical services related to HIV/AIDS. This systematic review assessed inequities in knowledge, attitude, HIV testing, and ART coverage across individual-level social groups and multiple (dis)advantage categories. METHODS: This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline, with a PROSPERO registration number CRD42024521247. The risk of bias was assessed by using Hoy et al's and Joanna Brigg's quality appraisal checklists for cross-sectional quantitative and qualitative studies, respectively. The search date was from inception to the final database search date (May 29, 2023). The included articles were either quantitative or qualitative studies. We used mixed-methods approach to analyse the data from the review articles. Quantitative descriptive analysis was conducted to estimate frequency of articles published from different countries around the world. Qualitative content analysis of the findings from the original studies was conducted using the PROGRESS plus framework which stands for: place of residence, occupation or employment status, gender, religion, education status, socioeconomic status, and social capital. RESULTS: Out of 6,029 articles that were accessed and screened, only 72 articles met the inclusion criteria. More articles on HIV-related equity in knowledge, attitude, testing, and ART were published in developed countries than in developing countries. Individuals from higher-income households had better knowledge about HIV/AIDS. Unfavourable attitudes towards people living with HIV and HIV/AIDS-associated stigma were common among women. HIV/AIDS service coverage (HIV testing or ART coverage) was higher among richer and urban residents. HIV/AIDS-associated stigma and lower levels of knowledge about HIV/AIDS were observed among multiple disadvantageous groups due to the intersection of two or more identities. CONCLUSIONS: The current review revealed that there have been disparities in HIV/AIDS services between social classes. Ending service disparity towards the global threat of HIV/AIDS demands tailored interventions based on socially disadvantaged groups (e.g., poor, rural dwellers, and women) and intersectional determinants. There is a need to understand the deep-rooted causes of inequity and the challenges that an equity-oriented system faces over time. More studies on inequity are needed, including intersectional inequity, which has been rarely studied in developing countries.

Human T-cell leukaemia virus type 1 and Adult T-cell leukaemia/lymphoma in Queensland, Australia: a retrospective cross-sectional study.

OBJECTIVES: Human T-cell leukaemia virus type 1 (HTLV-1), an STI, is reported to be highly prevalent in Indigenous communities in Central Australia. HTLV-1 is an incurable, chronic infection which can cause Adult T-cell leukaemia/lymphoma (ATL). ATL is associated with high morbidity and mortality, with limited treatment options. We studied the prevalence of HTLV-1 and ATL in the state of Queensland, Australia. METHODS: Serum samples stored at healthcare services in Brisbane, Townsville and Cairns and at haemodialysis units in Brisbane (2018-2019) were screened for HTLV-1/2 antibodies using the Abbott ARCHITECT chemiluminescent microparticle immunoassay (CMIA) for antibodies against gp46-I, gp46-II and GD21 (Abbott CMIA, ARCHITECT). Reactive samples were confirmed through Western blot. Pooled Australian National Cancer Registry surveillance data reporting on cases coded for ATL (2004-2015) were analysed. RESULTS: Two out of 2000 hospital and health services samples were confirmed HTLV-1-positive (0.1%, 95% CI 0.02% to 0.4%), both in older women, one Indigenous and one non-Indigenous. All 540 haemodialysis samples tested negative for HTLV. All samples were HTLV-2-negative. Ten out of 42 (24.8%) reported cases of ATL in Australia were from Queensland (crude incidence rate 0.025/100 000; 95% CI 0.011 to 0.045); most cases were seen in adult men of non-Indigenous origin. Nineteen deaths due to ATL were recorded in Australia. CONCLUSION: We confirm that HTLV-1 and ATL were detected in Queensland in Indigenous and non-Indigenous people. These results highlight the need for HTLV-1 prevalence studies in populations at risk of STIs to allow the implementation of focused public health sexual and mother-to-child transmission prevention strategies.

STI and HIV testing: examining factors that influence uptake among domestic Australian-born, domestic overseas-born and international tertiary students studying in Australia.

OBJECTIVES: Sexual health knowledge among international students in Australia is lower than domestic students, however, little is known about what factors affect the uptake of STI testing, nor if there are differences for overseas-born domestic students. METHODS: We included sexually active respondents from a survey of university students in Australia (N = 3,075). Multivariate regression and mediation analyses investigated associations of STI and HIV testing with STI and HIV knowledge respectively, sexual risk behaviour and demographics, including comparisons among: domestic Australian-born, domestic overseas-born, and international students. RESULTS: STI and HIV knowledge was positively associated with STI and HIV testing respectively (STI OR = 1.13, 95% CI: 1.09, 1.16; HIV OR = 1.37, 95% CI: 1.27, 1.48). STI knowledge was significantly lower for international than domestic Australian-born students (10.8 vs. 12.2 out of 16), as was STI testing (32% vs. 38%); the difference in knowledge accounted for half the difference in STI testing rates between these two groups. International students from Southern Asia, and Eastern Asia reported the lowest STI testing rates. HIV testing was highest amongst international students from Africa and North America. Higher sexual risk behaviour, younger age, and identifying as gay or bisexual were positively associated with higher STI and HIV testing rates. CONCLUSIONS: Our study supports greater investment and commitment by universities for the provision of sexual health education that can promote access to testing to improve the health of their students.

Analysis of the COVID-19 pandemic: lessons towards a more effective response to public health emergencies.

BACKGROUND: The pandemic of Coronavirus Disease 2019 (COVID-19) is a timely reminder of the nature and impact of Public Health Emergencies of International Concern. As of 12 January 2022, there were over 314 million cases and over 5.5 million deaths notified since the start of the pandemic. The COVID-19 pandemic takes variable shapes and forms, in terms of cases and deaths, in different regions and countries of the world. The objective of this study is to analyse the variable expression of COVID-19 pandemic so that lessons can be learned towards an effective public health emergency response. METHODS: We conducted a mixed-methods study to understand the heterogeneity of cases and deaths due to the COVID-19 pandemic. Correlation analysis and scatter plot were employed for the quantitative data. We used Spearman's correlation analysis to determine relationship strength between cases and deaths and socio-economic and health systems. We organized qualitative information from the literature and conducted a thematic analysis to recognize patterns of cases and deaths and explain the findings from the quantitative data. RESULTS: We have found that regions and countries with high human development index have higher cases and deaths per million population due to COVID-19. This is due to international connectedness and mobility of their population related to trade and tourism, and their vulnerability related to older populations and higher rates of non-communicable diseases. We have also identified that the burden of the pandemic is also variable among high- and middle-income countries due to differences in the governance of the pandemic, fragmentation of health systems, and socio-economic inequities. CONCLUSION: The COVID-19 pandemic demonstrates that every country remains vulnerable to public health emergencies. The aspiration towards a healthier and safer society requires that countries develop and implement a coherent and context-specific national strategy, improve governance of public health emergencies, build the capacity of their (public) health systems, minimize fragmentation, and tackle upstream structural issues, including socio-economic inequities. This is possible through a primary health care approach, which ensures provision of universal and equitable promotive, preventive and curative services, through whole-of-government and whole-of-society approaches.

Factors associated with pyomyositis: A systematic review and meta-analysis.

OBJECTIVES: Pyomyositis, an acute bacterial infection of skeletal muscle usually resulting in abscess formation, is well recognised in tropical regions where it can account for up to 4% of adult surgical admissions. It is increasingly being reported from high-income temperate countries. Pyomyositis occurs across all ages and in both sexes. Mortality ranges from 1% to 23%. Many risk factors have been suggested. We aimed to identify factors associated with pyomyositis. METHODS: We undertook a systematic review and meta-analysis, using PubMed, EMBASE, Scopus and the Cochran Library and hand-searching published papers. The random-effects model meta-analysis was used to calculate pooled estimated odd ratios with the corresponding 95% confidence interval. RESULTS: All studies in the systematic review (n = 25) and the meta-analysis (n = 12) were hospital-based. Seven only included children. Relatively few studies have been published in the last decade, the majority of which are from high-income temperate settings. Staphylococcus aureus was the main organism isolated. Males under the age of 20 predominated, and mortality of up to 20% was reported. Factors associated with pyomyositis were HIV infection (OR = 4.82; 95% CI: 1.67-13.92) and fulfilling an AIDS surveillance definition (OR = 6.08; 95% CI: 2.79-13.23). CONCLUSIONS: Our meta-analysis indicated significant associations between pyomyositis infection and HIV/AIDS. Major gaps in our understanding of the epidemiology, pathogenesis, clinical presentation, and outcome remain, highlighting the need for further research and more systematic studies. Pyomyositis merits consideration as a neglected tropical disease.

Economic evaluation of alternative testing regimes and settings to detect undiagnosed HIV in Australia.

BACKGROUND: The study aimed to estimate the comparative costs per positive diagnosis of previously undetected HIV in three testing regimes: conventional; parallel and point of care (POC) testing. The regimes are analysed in six testing settings in Australia where infection is concentrated but with low prevalence. METHODS: A cost model was developed to highlight the trade-offs between test and economic efficiency from a provider perspective. First, an estimate of the number of tests needed to find a true (previously undiagnosed) positive diagnosis was made. Second, estimates of the average cost per positive diagnosis in whole of population (WoP) and men who have sex with men (MSM) was made, then third, aggregated to the total cost for diagnosis of all undetected infections. RESULTS: Parallel testing is as effective as conventional testing, but more economically efficient. POC testing provide two significant advantages over conventional testing: they screen out negatives effectively at comparatively lower cost and, with confirmatory testing of reactive results, there is no loss in efficiency. The average and total costs per detection in WoP are prohibitive, except for Home Self Testing. The diagnosis in MSM is cost effective in all settings, but especially using Home Self Testing when the individual assumes the cost of testing. CONCLUSIONS: This study illustrates the trade-offs between economic and test efficiency and their interactions with population(s) prevalence. The efficient testing regimes and settings are presently under or not funded in Australia. Home Self Testing has the potential to dramatically increase testing rates at very little cost.

STI and HIV knowledge and testing: a comparison of domestic Australian-born, domestic overseas-born and international university students in Australia.

University students usually consist of young people from culturally and linguistically diverse backgrounds, and a group recognised as being at increased risk of STI. This study found lower levels of STI knowledge and STI testing among international students and to a lesser extent, domestic overseas-born students, compared with domestic Australian-born students. International students exhibited lower risk sexual behaviour but were more likely to have had a HIV test than domestic students. This diversity in sexual health knowledge, sexual health services utilisation and sexual experience indicates the need for a variety of public health approaches to improve sexual health.

Primary health care contributions to universal health coverage, Ethiopia.

Many global health institutions, including the World Health Organization, consider primary health care as the path towards achieving universal health coverage (UHC). However, there remain concerns about the feasibility and effectiveness of this approach in low-resource countries. Ethiopia has been implementing the primary health-care approach since the mid-1970s, with primary health care at the core of the health system since 1993. Nevertheless, comprehensive and systemic evidence on the practice and role of primary health care towards UHC is lacking in Ethiopia. We made a document review of publicly available qualitative and quantitative data. Using the framework of the Primary Health Care Performance Initiative we describe and analyse the practice of primary health care and identify successes and challenges. Implementation of the primary health-care approach in Ethiopia has been possible through policies, strategies and programmes that are aligned with country priorities. There has been a diagonal approach to disease control programmes along with health-systems strengthening, community empowerment and multisectoral action. These strategies have enabled the country to increase health services coverage and improve the population's health status. However, key challenges remain to be addressed, including inadequate coverage of services, inequity of access, slow health-systems transition to provide services for noncommunicable diseases, inadequate quality of care, and high out-of-pocket expenditure. To resolve gaps in the health system and beyond, the country needs to improve its domestic financing for health and target disadvantaged locations and populations through a precision public health approach. These challenges need to be addressed through the whole sustainable development agenda.

De nombreux organismes sanitaires internationaux, dont l'Organisation mondiale de la Santé, considèrent que les soins de santé primaires représentent un jalon essentiel du cheminement vers une couverture maladie universelle (CMU). Néanmoins, des inquiétudes subsistent quant à la faisabilité et à l'efficacité de cette approche dans les pays à faible revenu. L'Éthiopie a adopté cette approche depuis le milieu des années 1970, et les soins de santé primaires figurent au cœur du système sanitaire depuis 1993. Pourtant, rares sont les preuves exhaustives et généralisées concernant la pratique et le rôle des soins de santé primaires dans l'évolution vers une CMU en Éthiopie. Nous avons donc procédé à un examen des documents contenant des données qualitatives et quantitatives accessibles au public. À l'aide du cadre instauré par l'initiative PHCPI (Primary Health Care Performance Initiative), nous avons décrit et analysé la pratique des soins de santé primaires; nous avons également identifié les réussites et les défis. C'est grâce à des politiques, stratégies et programmes en adéquation avec les priorités nationales que cette méthode axée sur les soins de santé primaires a pu être mise en œuvre en Éthiopie. Le pays a emprunté une approche diagonale vis-à-vis des programmes de contrôle des maladies, tout en renforçant les systèmes de santé, l'autonomie des communautés et l'action multisectorielle. Ces stratégies lui ont permis d'augmenter la prise en charge des services de santé et d'améliorer l'état de santé de la population. Il reste cependant d'importants défis à relever: couverture insuffisante des services, inégalités d'accès, lenteur de transition entre systèmes sanitaires pour la fourniture de prestations liées aux maladies non transmissibles, qualité médiocre des soins et frais non remboursables élevés. Afin de combler les lacunes au sein et en dehors du système de santé, le pays doit revoir le montant du financement octroyé aux soins de santé à la hausse, mais aussi cibler les régions et populations défavorisées par le biais d'une approche de précision en matière de santé publique. Ces défis doivent être abordés tout au long du programme de développement durable.

Varias instituciones sanitarias mundiales, incluida la Organización Mundial de la Salud, opinan que la atención primaria de salud es la vía hacia el logro de la cobertura sanitaria universal (CSU). Sin embargo, persisten las preocupaciones acerca de la viabilidad y la eficacia de este enfoque en los países de bajos recursos. Etiopía aplica el enfoque de la atención primaria de salud desde mediados del decenio de 1970, por lo que la atención primaria de salud es el núcleo del sistema de salud desde 1993. No obstante, Etiopía carece de pruebas integrales y generales sobre la práctica y la función de la atención primaria de salud orientada a la CSU. Se realizó un análisis documental de los datos cualitativos y cuantitativos a disposición del público. Se describe y analiza la práctica de la atención primaria de salud y se determinan los éxitos y los desafíos por medio del marco de la Iniciativa sobre el desempeño de la atención primaria de salud. La aplicación del enfoque de la atención primaria de salud en Etiopía fue posible gracias a las políticas, las estrategias y los programas que se adaptaron a las prioridades del país. Existe un enfoque diagonal de los programas de control de enfermedades sumado al fortalecimiento de los sistemas sanitarios, a la participación de la comunidad y a las medidas multisectoriales. Gracias a estas estrategias, el país ha logrado aumentar la cobertura de los servicios sanitarios y mejorar el estado de salud de la población. Sin embargo, aún quedan por resolver algunos desafíos fundamentales, como la cobertura insuficiente de los servicios, la falta de equidad en el acceso, la lentitud de la transición de los sistemas sanitarios para prestar los servicios correspondientes a las enfermedades no transmisibles, la calidad deficiente de la atención y los elevados gastos de bolsillo. Para resolver las deficiencias del sistema sanitario y otros aspectos, el país debe mejorar su financiamiento nacional para la salud y centrarse en los lugares y las poblaciones desfavorecidos a través de un enfoque preciso de la salud pública. Se debe abordar estos desafíos en todo el programa de desarrollo sostenible.

Leaving no one behind: lessons from implementation of policies for universal HIV treatment to universal health coverage.

BACKGROUND: The third Sustainable Development Goal (SDG - 3) aims to ensure healthy lives and promote well-being for all at all ages. SDG-3 has a specific target on universal health coverage (UHC), which emphasizes the importance of all people and communities having access to quality health services without risking financial hardship. The objective of this study is to review progress towards UHC using antiretroviral treatment (ART) as a case study. METHODS: We used a mixed-methods design including qualitative and quantitative approaches. We reviewed and synthesised the evidence on the evolution of the WHO HIV treatment guidelines between 2002 and 2019. We calculated ART coverage over time by gender, age group, and location. We also estimated ART coverage differences and ratios. FINDINGS: ART guidelines have evolved from "treating the sickest" to "treating all". ART coverage increased globally from under 7% in 2005 to 62% in 2018. There have been successes in increasing ART coverage in all populations and locations. However, progress varies by population and location in many regions. There is inequity in ART coverage: women (68%) versus men (55%), and adults (62%) versus children (54%). This inequity has widened over time, and with expanded ART eligibility criteria. On the other hand, data from at least one high-burden country (Ethiopia) shows that inequity among regions has narrowed over time due to the improvements in the primary health care systems and implementation of the public health approach in the country. CONCLUSION: ART coverage has increased at global, regional and national levels to all population groups. However, the gains have not been equitable among locations and populations. Policies towards universality may widen the inequity in resource-limited settings unless countries take precautions and "put the last first". We argue that primary health care and public health approaches, with multi-sectoral actions and community engagement, are vital to minimize inequity, achieve UHC and leave no one behind.

Australian interdisciplinary healthcare providers' perspectives on the effects of broader pre-exposure prophylaxis (PrEP) access on uptake and service delivery: a qualitative study.

Background The addition of pre-exposure prophylaxis (PrEP) for HIV prevention to the Australian Government-subsidised Pharmaceutical Benefits Scheme (PBS) enables any doctor or nurse practitioner to prescribe it and has increased accessibility options. However, understanding of Australian healthcare providers' (HCP) knowledge and preparedness to prescribe PrEP remains limited. METHODS: Semistructured interviews, conducted before PBS listing (October 2016-April 2017), explored PrEP knowledge and prescription experiences of 51 multidisciplinary HCPs involved with the Queensland Pre-Exposure Prophylaxis Demonstration study. RESULTS: Thematic analysis revealed that participants viewed PrEP as a necessary HIV prevention option, but there was concern about confusing prevention messages and potential risk compensation. Clinical capacity, stigma, cultural norms, rural access and PrEP-associated costs were identified as barriers to access and uptake. Some of these barriers may be addressed by the PBS listing; nonetheless, there was strong specialist concern about the preparedness of general practitioners without sexual health experience to prescribe PrEP. Participants identified a need to educate all HCPs, implement multidisciplinary supply models and provide timely access to PrEP for vulnerable populations and those ineligible for Medicare (Australia's universal healthcare insurance system). CONCLUSIONS: Although PrEP listing on the PBS addressed structural barriers to access, this study highlights the role of nurses and other interdisciplinary healthcare workers in the provision of PrEP in addressing the sociocultural barriers that still affect the access of certain populations to HIV prevention measures. These findings will inform further professional training as PrEP is more widely accessed and requested outside specialist sexual health services. Future work is needed to ensure that the primary healthcare workforce is prepared to provide competent and safe access to PrEP across diverse locations and population groups.

Peer-delivered point-of-care testing for Chlamydia trachomatis and Neisseria gonorrhoeae within an urban community setting: a cross-sectional analysis.

Background The advent of fully automated nucleic acid amplification test (NAAT) technology brings new public health opportunities to provide Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) point-of-care testing (POCT) in non-traditional settings. METHODS: This pilot study evaluated the integration of the CT/NG Xpert diagnostic assay into an urban peer-led community setting providing HIV and syphilis POCT. A comprehensive protocol of testing, result notification, referral and follow up, managed by peer test facilitators, was undertaken. RESULTS: Over 67 weeks, there were 4523 occasions of CT/NG testing using urine, oropharyngeal and anorectal samples with 25.7% (803) of the 3123 unique participants returning for repeat testing. The prevalence of CT and NG was 9.5% and 5.4% respectively. Where CT and or NG infection was detected, 98.4% (604/614) of participants were successfully notified of detected infection and referred for treatment. Evaluation Survey responses (11.4%, 516/4523) indicated a substantial proportion of respondents (27.1%, 140/516) 'would not have tested anywhere else'. Of note, 17.8% (92/516) of participants reported no previous CT/NG test and an additional 17.8% (92/516) reported testing more than 12 months ago. A total of 95.9% (495/516) of participants 'Strongly agreed' or 'Agreed' to being satisfied with the service. CONCLUSION: The project successfully demonstrated an acceptable and feasible model for a peer-delivered community-led service to provide targeted molecular CT/NG POCT. This model offers capacity to move beyond the traditional pathology and STI testing services and establish community-led models that build trust and increase testing rates for key populations of epidemiological significance.

Reduced sensitivity from pooled urine, pharyngeal and rectal specimens when using a molecular assay for the detection of chlamydia and gonorrhoea near the point of care.

Background The aim of this study was to compare the performance of pooled self-collected urogenital, pharyngeal and anorectal specimens to that of individual specimen results for the molecular detection of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) near the point of care (POC) for diagnostic sensitivity. METHODS: Clients (mostly men who have sex with men) attending an urban community testing service and three sex-on-premises venues in Brisbane, Australia, were offered CT and NG testing by trained lay providers. Participants provided three self-collected specimens (urine, pharyngeal and rectal) for testing by GeneXpert (Cepheid, Sunnyvale, CA, USA). If any of the individual specimens from a participant were positive, all three specimens were pooled and retested. RESULTS: Of the 388 participants who provided three individual anatomical specimens, 76 (19.6%) were found to be positive for CT and/or NG at one or more sites. The pooling approach failed to detect five CT rectal and four NG pharyngeal infections. The overall performance (sensitivity) of the pooling approach compared with individual specimen testing and Cohen's κ were 90.0% and 0.86 respectively for CT and 89.7% and 0.89 respectively for NG. CONCLUSIONS: Reduced sensitivity was observed when using pooled specimens for the detection of CT and NG using GeneXpert near the POC, similar to results reported in laboratory-based CT and NG pooling studies. These data suggest specimen pooling is feasible near to the POC, potentially saving time and costs when screening at-risk populations for CT and NG. Our data also suggest a reduction in pooled urine could improve overall test sensitivity.

HIV Prevalence Among Tuberculosis Patients in Sub-Saharan Africa: A Systematic Review and Meta-analysis.

HIV associated tuberculosis (TB) morbidity and mortality is a major concern in sub-Saharan Africa. Understanding the level of HIV infection among TB patients is vital for adequate response. We conducted a systematic review and meta-analysis to estimate the prevalence of HIV in TB patients in sub-Saharan Africa. We searched PubMed, EMBASE, Web of Science and CINAHL databases. A meta-analysis with a random-effects model was performed. Potential sources of heterogeneity in the prevalence estimates were explored using meta-regression analysis. We identified 68 studies that collectively included 62,969 TB patients between 1990 and 2017. The overall estimate of HIV prevalence in TB patients was 31.8% (95% CI 27.8-36.1). There was substantial heterogeneity in the prevalence estimates in Southern, Central, Eastern, and Western sub-Saharan Africa regions (43.7, 41.3, 31.1 and 25.5%, respectively). We noted an apparent reduction in the estimate from 33.7% (95% CI 27.6-40.4) in the period before 2000 to 25.7% (95% CI 17.6-336.6) in the period after 2010. The Eastern and Southern sub-Saharan Africa region had higher prevalence [34.4% (95% CI 29.3-34.4)] than the Western and Central region [27.3% (95% CI 21.6-33.8)]. The prevalence of HIV in TB patients has declined over time in sub-Saharan Africa. We argue that this is due to strengthened HIV prevention and control response and enhanced TB/HIV collaborative activities. Countries and regions with high burdens of HIV and TB should strengthen and sustain efforts in order to achieve the goal of ending both HIV and TB epidemics in line with the Sustainable Development Goals.

Integrated HIV self-testing (HIVST) service delivery in Queensland for policy and service development: study protocol.

This study aims to pilot and evaluate an integrated model for HIV self-testing (HIVST) service delivery in a peer-led Queensland community setting to increase access to HIVST, particularly for men who have sex with men (MSM) living in regional, remote and rural areas. It seeks to provide evidence that would overcome some of the key objections previously raised to HIVST. Recruitment strategies have been designed to engage hard to reach MSM populations in testing. Awareness of the trial will be generated through advertising on social media platforms, including dating applications, word of mouth and HIV related websites. Participants will access an HIVST online ordering system hosted by a HIV community organisation. This system: (1) enables on-line informed consent; 2) gives clients the choice to accept verbal pre-test information from a trained peer test facilitator or not; and (3) allows for ordering of the HIVST kit after completion of an online survey (with demographic information and testing history etc.). Clients receive the kits via the post; and at 2 weeks receive a follow-up phone-call and SMS link to a post-test survey. If the test is non-reactive, clients can opt for test reminders. If reactive, referral to clinical services, peer navigation and support systems are provided. This study addresses important gaps in understanding of acceptable and feasible methods to integrate HIVST into an existing peer-led testing service and into the broader suite of HIV testing options and services. The findings will inform the actions needed to enhance access to HIVST for MSM wishing to use this technology in Australia and elsewhere, especially those who have never tested and infrequent testers.

Implications of the on-line market for regulation and uptake of HIV self-testing in Australia.

Self-Testing for HIV (HIVST) is widely recognised as a feasible and effective means of increasing rates of testing and detection of HIV, particularly in non-testing and infrequent testing populations. Currently in Australia, the only means of accessing this technology is to purchase unregulated products on-line. A search of available on-line distributers was purposefully performed from the perspective of an English-speaking individual, with no clinical background or specific understanding of HIV testing practices, seeking to determine their HIV status. Purchased kits were assessed against a structured extraction tool based on the Australian Therapeutic Goods Administration (TGA) HIV testing clinical performance guidelines. In total, eight HIVST kits were purchased from seven different distributers. Analysis of the purchased kits and linked websites revealed that none met the TGA's requirements for HIV testing kits intended for home use; none also conformed to the additional recommendations for information, quality and links to services developed from this study's review of HIVST associated literature. People seeking HIVST kits are able to purchase sub-standard products that ill-serve their needs, and do so at a time of great personal vulnerability. The fact that Australians are willing to purchase and use these sub-standard products indicates HIVST is in demand. Health policy and models of service are needed in order to ensure people have access to a safe and effective registered device at prices that enable equity of access to all Australians, particularly those most at risk of HIV. Other countries awaiting access to regulated HIVST devices also need to consider the potential implications. Collaboration between manufacturers, distributers, regulatory bodies, service providers and the community is needed globally in order to ensure HIVST is embedded into testing methods in a manner that does not disrupt but rather safely and effectively increases HIV testing rates.

The virological durability of first-line ART among HIV-positive adult patients in resource limited settings without virological monitoring: a retrospective analysis of DART trial data.

BACKGROUND: Few low-income countries have virological monitoring widely available. We estimated the virological durability of first-line antiretroviral therapy (ART) after five years of follow-up among adult Ugandan and Zimbabwean patients in the DART study, in which virological assays were conducted retrospectively. METHODS: DART compared clinically driven monitoring with/without routine CD4 measurement. Annual plasma viral load was measured on 1,762 patients. Analytical weights were calculated based on the inverse probability of sampling. Time to virological failure, defined as the first viral load measurement ≥200 copies/mL after 48 weeks of ART, was analysed using Kaplan-Meier plots and Cox regression models. RESULTS: Overall, 65% of DART trial patients were female. Patients initiated first-line ART at a median (interquartile range; IQR) age of 37 (32-42) and with a median CD4 cell count of 86 (32-140). After 240 weeks of ART, patients initiating dual-class nucleoside reverse-transcriptase inhibitor (NRTI) -non-nucleoside reverse-transcriptase (NNRTI) regimens containing nevirapine + zidovudine + lamivudine had a lower incidence of virological failure than patients on triple-NRTI regimens containing tenofovir + zidovudine + lamivudine (21% vs 40%; hazard ratio (HR) =0.48, 95% CI:0.38-0.62; p < 0.0001). In multivariate analyses, female patients (HR = 0.79, 95% CI: 0.65-0.95; p = 0.02), older patients (HR = 0.73 per 10 years, 95% CI: 0.64-0.84; p < 0.0001) and patients with a higher pre-ART CD4 cell count (HR = 0.64 per 100 cells/mm3, 95% CI: 0.54-0.75; p < 0.0001) had a lower incidence of virological failure after adjusting for adherence to ART. No difference in failure rate between the two randomised monitoring strategies was observed (p= 0.25). CONCLUSIONS: The long-term durability of virological suppression on dual-class NRTI-NNRTI first-line ART without virological monitoring is remarkable and is enabled by high-quality clinical management and a consistent drug supply. To achieve higher rates of virological suppression viral-load-informed differentiated care may be required. TRIAL REGISTRATION: Prospectively registered on 18/10/2000 as ISRCTN13968779 .

Shifting human resources for health in the context of ART provision: qualitative and quantitative findings from the Lablite baseline study.

BACKGROUND: Lablite is an implementation project supporting and studying decentralized antiretroviral therapy (ART) rollout to rural communities in Malawi, Uganda and Zimbabwe. Task shifting is one of the strategies to deal with shortage of health care workers (HCWs) in ART provision. Evaluating Human Resources for Health (HRH) optimization is essential for ensuring access to ART. The Lablite project started with a baseline survey whose aim was to describe and compare national and intercountry delivery of ART services including training, use of laboratories and clinical care. METHODS: A cross-sectional survey was conducted between October 2011 and August 2012 in a sample of 81 health facilities representing different regions, facility levels and experience of ART provision in Malawi, Uganda and Zimbabwe. Using a questionnaire, data were collected on facility characteristics, human resources and service provision. Thirty three (33) focus group discussions were conducted with HCWs in a subset of facilities in Malawi and Zimbabwe. RESULTS: The survey results showed that in Malawi and Uganda, primary care facilities were run by non-physician clinical officers/medical assistants while in Zimbabwe, they were run by nurses/midwives. Across the three countries, turnover of staff was high especially among nurses. Between 10 and 20% of the facilities had at least one clinical officer/medical assistant leave in the 3 months prior to the study. Qualitative results show that HCWs in ART and non-ART facilities perceived a shortage of staff for all services, even prior to the introduction of ART provision. HCWs perceived the introduction of ART as having increased workload. In Malawi, the number of people on ART and hence the workload for HCWs has further increased following the introduction of Option B+ (ART initiation and life-long treatment for HIV positive pregnant and lactating women), resulting in extended working times and concerns that the quality of services have been affected. For some HCWs, perceived low salaries, extended working schedules, lack of training opportunities and inadequate infrastructure for service provision were linked to low job satisfaction and motivation. CONCLUSIONS: ART has been decentralized to lower level facilities in the context of an ongoing HRH crisis and staff shortage, which may compromise the provision of high-quality ART services. Task shifting interventions need adequate resources, relevant training opportunities, and innovative strategies to optimize the operationalization of new WHO treatment guidelines which continue to expand the number of people eligible for ART.

The Impact of Different CD4 Cell-Count Monitoring and Switching Strategies on Mortality in HIV-Infected African Adults on Antiretroviral Therapy: An Application of Dynamic Marginal Structural Models.

In Africa, antiretroviral therapy (ART) is delivered with limited laboratory monitoring, often none. In 2003-2004, investigators in the Development of Antiretroviral Therapy in Africa (DART) Trial randomized persons initiating ART in Uganda and Zimbabwe to either laboratory and clinical monitoring (LCM) or clinically driven monitoring (CDM). CD4 cell counts were measured every 12 weeks in both groups but were only returned to treating clinicians for management in the LCM group. Follow-up continued through 2008. In observational analyses, dynamic marginal structural models on pooled randomized groups were used to estimate survival under different monitoring-frequency and clinical/immunological switching strategies. Assumptions included no direct effect of randomized group on mortality or confounders and no unmeasured confounders which influenced treatment switch and mortality or treatment switch and time-dependent covariates. After 48 weeks of first-line ART, 2,946 individuals contributed 11,351 person-years of follow-up, 625 switches, and 179 deaths. The estimated survival probability after a further 240 weeks for post-48-week switch at the first CD4 cell count less than 100 cells/mm(3) or non-Candida World Health Organization stage 4 event (with CD4 count <250) was 0.96 (95% confidence interval (CI): 0.94, 0.97) with 12-weekly CD4 testing, 0.96 (95% CI: 0.95, 0.97) with 24-weekly CD4 testing, 0.95 (95% CI: 0.93, 0.96) with a single CD4 test at 48 weeks (baseline), and 0.92 (95% CI: 0.91, 0.94) with no CD4 testing. Comparing randomized groups by 48-week CD4 count, the mortality risk associated with CDM versus LCM was greater in persons with CD4 counts of <100 (hazard ratio = 2.4, 95% CI: 1.3, 4.3) than in those with CD4 counts of ≥100 (hazard ratio = 1.1, 95% CI: 0.8, 1.7; interaction P = 0.04). These findings support a benefit from identifying patients immunologically failing first-line ART at 48 weeks.
