RESUMO
BACKGROUND: Aspirational targets to end AIDS by 2030 include having 95% of people with human immunodeficiency virus (HIV; PWH) diagnosed, 95% treated, and 95% with controlled viral load (VL). Our objective was to describe, using a large French prospective cohort, the median transition times through the cascade of care between 2009 and 2019. METHODS: We analyzed patients whose first HIV diagnosis was made between 1 January 2009 and 31 December 2019. Using the Kaplan-Meier method, we estimated the time to linkage to care (from HIV diagnosis to first biological assessment), to treatment (date of first antiretroviral therapy [ART] prescription), and to controlled VL (first value <200 copies/mL). Analyses were disaggregated by time periods and patients' characteristics. Censoring date was 31 December 2021. RESULTS: Among the 16 864 patients linked to care since 2009, the median [Q1; Q3] time from HIV diagnosis to controlled VL decreased from 254 [127-745] to 73 [48-132] days in 2009-2011 and 2018-2019, respectively. Transition times from linkage to care to first ART decreased from 67 [17; 414] in 2009-2011 to 13 [5; 26] days in 2018-2019, and from ART to controlled VL from 83 [35; 130] in 2009-2011 to 38 [28; 90] days in 2018-2019. Differences were observed depending on patients' characteristics. CONCLUSIONS: We describe drastic reductions in transition time through the cascade of care, allowing reduction in the transmission period following each new infection. Delayed diagnosis remains the main obstacle to ending AIDS in the next decade.

Widespread screening for hepatitis C virus (HCV) is necessary for Canada to meet its HCV elimination goals by 2030. People who currently or previously injected drugs are at high risk for HCV. Opioid agonist therapy (OAT, such as methadone and buprenorphine) has been shown to help stabilize the lives of people who are opioid-dependent. The distribution of OAT in North America typically requires daily, weekly, or monthly clinic visits and presents an opportunity for engagement, screening and treatment for those at high-risk of HCV. In this study, HCV screening was conducted by staff at OAT clinics in Ontario from 2016 to 2020 and those with chronic infections were treated on-site with direct-acting antivirals. Point-of-care or dried blood spot (DBS) testing was used for antibodies, DBS or serum for HCV RNA and serum for HCV RNA at SVR12 (sustained virological response). Clinics screened 1954 people (mean age 40 years ±12, 63% male). Forty-five percent were antibody positive, of whom 64% were HCV RNA+. Eighty percent of those RNA+ set an appointment in which 99% attended. Ninety-six percent started treatment with 87% completing treatment. Sixty-eight percent of people who completed treatment submitted a sample for SVR12 testing of which 97% achieved a virological cure. Results suggest that HCV screening and treatment at OAT clinics is feasible, effective and warrants expansion. Data suggest strong treatment adherence due to high rates of SVR12 comparable with other OAT-based HCV treatment programs. The lack of SVR12 sampling could be addressed by either on-site phlebotomy or incentivizing SVR12 sampling.

BACKGROUND AND AIMS: Previous studies have shown suboptimal screening for hepatitis D virus (HDV) among patients with chronic hepatitis B (CHB). This study presents the cascade of care for HDV infection in a major secondary referral centre in Southern Stockholm, Sweden. METHODS: HBsAg+ve patients attending Karolinska University Hospital (KUH) from 1992 to 2022 were identified. The prevalence of anti-HDV and/or HDV RNA positivity, interferon (IFN) therapy and maintained virological responses (MVR) after HDV treatment were assessed. Also, time to anti-HDV testing was analysed in relation to liver-related outcomes with logistic regression. RESULTS: Among 4095 HBsAg+ve persons, 3703 (90.4%) underwent an anti-HDV screening; within a median of 1.8 months (range 0.0-57.1) after CHB diagnosis. This screening rate increased over time, to 97.9% in the last decade. Overall, 310 (8.4%) were anti-HDV+ve, of which 202 (65.2%) were HDV RNA+ve. Eighty-five (42%) received IFN, and 9 (10.6%) achieved MVR at the last follow-up. The predictive factors for anti-HDV screening were Asian origin, diagnosis after the year 2012, HIV co-infection (negative factor) and HBV DNA level < 2000 IU/mL in univariable analysis, while HIV co-infection was the only remaining factor in multivariable analysis. Delayed anti-HDV test >5 years was independently associated with worsened liver-related outcomes (adjusted odds ratio = 7.6, 95% CI 1.8-31.6). CONCLUSION: Higher frequency of HDV screening than previously published data could be seen among CHB patients at KUH in a low-endemic setting. Receiving a delayed screening test seems to be associated with worse outcomes, stressing the need of a strategy for timely HDV diagnosis.

BACKGROUND & AIMS: Hepatitis B infection is the most frequent cause of chronic hepatitis and liver cancer worldwide. Active searching for individuals with chronic hepatitis B has been proposed as a strategy to achieve the elimination of this virus. The primary aim of this study was to link to specialists HBsAg-positive individuals detected in a laboratory database and to characterize individuals who were not linked to care. METHODS: We performed a retrospective-prospective evaluation of all HBsAg-positive serum samples identified in the central laboratory of the Northern Barcelona area between January 2018 and June 2022. After reviewing the patients' clinical charts, all those not linked to care were given an appointment with a specialist. RESULTS: Medical records of 2765 different HBsAg-positive serum samples were reviewed and 2590 individuals were identified: 844 (32.6%) were not linked to a specialist, 653 were candidates for linkage, and 344 attended the specialist visit. The two main reasons why they were not under specialist care were administrative issues, such as living in another region (12.1%) and lacking contact details (4.1%), and low life expectancy (2.8%). Individuals who did not attend their scheduled visit were mainly young [38.1 ± 12.9 vs. 44.0 ± 14.0 (p < .001)], non-White European [75.3% vs. 58.1% (p < .001)] and men [70.7% vs. 56.4% (p < .001)]. CONCLUSIONS: One in every three HBsAg-positive individuals in our setting was not currently under specialist care. Of particular note, half of them had never attended a specialist consultation, an essential step for evaluating the disease and starting therapy in some countries.

Globally, Botswana has one of the highest burdens of HIV. This study estimated the impact of the COVID-19 pandemic on the HIV cascade of care in Sub-Saharan Africa. We conducted an interrupted time series analysis on national-level data to estimate the effect of COVID-19 on the numbers of HIV tests, positive HIV tests and ART initiations from April 2019 until March 2021. In multivariable Poisson interrupted time series regression, the COVID-19 lockdown was associated with a 27% decrease in the monthly numbers of HIV tests (IRR 0.73, 95%CI 0.72-0.73), a 25% decrease in HIV positive tests (IRR 0.75, 95%CI 0.71-0.79), and a 43% reduction in ART initiations (IRR 0.57, 95%CI 0.55-0.60). The impact of the pandemic on all three outcomes was worse in males and those aged ≥ 50 years. In conclusion, COVID-19 had a strong negative impact on HIV screening, diagnosis and ART initiation in Botswana.

BACKGROUND: Hypertension is a major risk factor for cardiovascular disease and all-cause mortality worldwide. Despite the widespread availability of effective antihypertensives, blood pressure (BP) control rates remain suboptimal, even in high-income countries such as Belgium. In this study, we used a cascade of care approach to identify where most patients are lost along the continuum of hypertension care in Belgium, and to assess the main risk factors for attrition at various stages of hypertension management. METHODS: Using cross-sectional data from the 2018 Belgian Health Interview Survey and the Belgian Health Examination Survey, we estimated hypertension prevalence among the Belgian population aged 40-79 years, and the proportion that was (1) screened, (2) diagnosed, (3) linked to care, (4) in treatment, (5) followed up and (6) well-controlled. Cox regression models were estimated to identify individual risk factors for being unlinked to hypertension care, untreated and not followed up appropriately. RESULTS: The prevalence of hypertension based on self-reported and measured high BP was 43.3%. While 98% of the hypertensive population had their BP measured in the past 5 years, only 56.7% were diagnosed. Furthermore, 53.4% were linked to care, 49.8% were in treatment and 43.4% received adequate follow-up. Less than a quarter (23.5%) achieved BP control. Among those diagnosed with hypertension, males, those of younger age, without comorbidities, and smokers, were more likely to be unlinked to care. Once in care, younger age, lower BMI, financial hardship, and psychological distress were associated with a higher risk of being untreated. Finally, among those treated for hypertension, females, those of younger age, and without comorbidities were more likely to receive no adequate follow-up. CONCLUSION: Our results show that undiagnosed hypertension is the most significant barrier to BP control in Belgium. Health interventions are thus needed to improve the accurate and timely diagnosis of hypertension. Once diagnosed, the Belgian health system retains patients fairly well along the continuum of hypertension care, yet targeted health interventions to improve hypertension management for high-risk groups remain necessary, especially with regard to improving treatment rates.

INTRODUCTION: Rates of substance use are high among youth involved in the legal system (YILS); however, YILS are less likely to initiate and complete substance use treatment compared to their non legally-involved peers. There are multiple steps involved in connecting youth to needed services, from screening and referral within the juvenile legal system to treatment initiation and completion within the behavioral health system. Understanding potential gaps in the care continuum requires data and decision-making from these two systems. The current study reports on the development of data dashboards that integrate these systems' data to help guide decisions to improve substance use screening and treatment for YILS, focusing on end-user feedback regarding dashboard utility. METHODS: Three focus groups were conducted with n = 21 end-users from juvenile legal systems and community mental health centers in front-line positions and in decision-making roles across 8 counties to gather feedback on an early version of the data dashboards; dashboards were then modified based on feedback. RESULTS: Qualitative analysis revealed topics related to (1) important aesthetic features of the dashboard, (2) user features such as filtering options and benchmarking to compare local data with other counties, and (3) the centrality of consistent terminology for data dashboard elements. Results also revealed the use of dashboards to facilitate collaboration between legal and behavioral health systems. CONCLUSIONS: Feedback from end-users highlight important design elements and dashboard utility as well as the challenges of working with cross-system and cross-jurisdiction data.

BackgroundActive follow-up of chronic hepatitis C notifications to promote linkage to care is a promising strategy to support elimination.AimThis pilot study in Victoria, Australia, explored if the Department of Health could follow-up on hepatitis C cases through their diagnosing clinicians, to assess and support linkage to care and complete data missing from the notification.MethodsFor notifications received between 1 September 2021 and 31 March 2022 of unspecified hepatitis C cases (i.e. acquired > 24 months ago or of unknown duration), contact with diagnosing clinicians was attempted. Data were collected on risk exposures, clinical and demographic characteristics and follow-up care (i.e. HCV RNA test; referral or ascertainment of previous negative testing or treatment history). Reasons for unsuccessful doctor contact and gaps in care provision were investigated. Advice to clinicians on care and resources for clinical support were given on demand.ResultsOf 513 cases where information was sought, this was able to be obtained for 356 (69.4%). Reasons for unsuccessful contact included incomplete contact details or difficulties getting in touch across three attempts, particularly for hospital diagnoses. Among the 356 cases, 307 (86.2%) had received follow-up care. Patient-management resources were requested by 100 of 286 contacted diagnosing clinicians.ConclusionsMost doctors successfully contacted had provided follow-up care. Missing contact information and the time taken to reach clinicians significantly impeded the feasibility of the intervention. Enhancing system automation, such as integration of laboratory results, could improve completeness of notifications and support further linkage to care where needed.

Background: Over the past decade, hospitals and health systems have increasingly adopted interventions to address the needs of patients with substance use disorders. The Opioid Use Disorder (OUD) Cascade of Care provides a framework for organizing and tracking patient health milestones over time and can assist health systems in identifying areas of intervention to maximize the impact of evidence-based services. However, detailed protocols are needed to guide health systems in how to operationalize the OUD Cascade and track outcomes using electronic health records.Objective: In this paper, we describe the process of operationalizing and applying the OUD Cascade in a large, urban, public hospital system.Methods: Through this case example, we describe the technical processes around data mining, as well as the decision-making processes, challenges encountered, lessons learned from compiling preliminary patient data and defining stages and outcome measures for the OUD Cascade of Care, and preliminary dataResults: We identified 33,616 (26.17% female) individuals with an OUD diagnosis. Almost half (48%) engaged with addiction services, while only 10.7% initiated medication-based treatment in an outpatient setting, 6.7% had timely follow-up, and 3.5% were retained for a minimum of 6 months.Conclusion: The current paper serves as a primer for other health systems seeking to implement data-informed approaches to guide more efficient care and improved substance use-related outcomes. An OUD Cascade of Care must be tailored to local systems based on inherent data limitations and services design with an emphasis on early stages wherein drop-off is the greatest.

BACKGROUND: The rising prevalence of fast-acting opioids in the USA suggests the increased need for non-professional first responder administration of naloxone. Effective administration of naloxone during an overdose requires that bystanders are familiar with, have access to, and know how to use naloxone. METHODS: Drawing on a statewide, address-based sample of Nebraskan adults, we used logistic regression to predict the likelihood of respondents' familiarity with, access to, and competency to administer naloxone. Our independent variables included measures indicating proximity to drug use, perceived community stigma toward people who use drugs, and demographic data. RESULTS: There were significant gaps in naloxone knowledge in Nebraska. Although 74.8% of respondents were familiar with naloxone, only 18.2% knew how to access it and 18.0% knew how to use it. Being close to an overdose experience, lifetime illicit opioid use, being close to a person who uses opioids, and having access to illicit opioids were not significantly associated with naloxone familiarity, access, or competency among respondents in Nebraska's two largest cities, Omaha and Lincoln. Outside of these cities, being close to a past overdose experience and access to illicit opioids was associated with higher odds of naloxone access and competency, but lifetime opioid use and being close to a person who uses opioids were not. Finally, among those familiar with naloxone, a higher perception of community stigma toward people who use opioids generally was associated with lower odds of naloxone access and competency. Higher perception of community stigma toward people who use heroin, methamphetamines, and cocaine, however, was associated with higher odds of naloxone access. CONCLUSIONS: Our findings highlight the continued need for education on naloxone with a specific focus on access and competency to further reduce opioid-related overdose deaths. Specific focus should be placed on promoting naloxone knowledge among people with a higher likelihood of needing to administer naloxone to reduce otherwise avoidable deaths. Further work is needed to understand differences in the relationship between substance-specific perceived stigma and its association with naloxone access.

Current HCV prevention efforts and treatment rates must improve for the United States (U.S.) to achieve WHO global elimination targets by 2030[1]. The current multi-day diagnosis and treatment paradigm for hepatitis C (HCV) infection leads to significant loss in the cascade of care, resulting in far fewer patients receiving treatment with direct acting antiviral agents (DAAs) than those diagnosed with HCV infection [2,3]. To achieve HCV elimination, a paradigm shift in access to HCV treatment is needed from current multi-day testing and treatment algorithms to same day diagnosis and treatment. This shift will require new tools, such as FDA-approved, CLIA-waived point-of-care (POC) antigen or nucleic acid tests (NAT) for HCV and HBV and NAT for HIV that do not require venous blood. Such a shift will also require better utilization of existing resources, expanding access to HCV treatment through availability of onsite treatment, removal of payer barriers to approval, adoption of minimal monitoring approaches during treatment, expanded access to available POC tests, and available specialist referral networks for patients who fail initial therapy, have advanced liver fibrosis, or have co-incident HIV or HBV infection. A same-day diagnosis and treatment paradigm will substantially contribute to HCV elimination by improving treatment rates for those diagnosed with HCV infection and expanding access to treatment in settings where patients have brief encounters with healthcare.
RESUMO
In Pakistan, substantial changes to hepatitis C virus (HCV) programming and treatment have occurred since the 2008 nationwide serosurvey estimated a 4.8% anti-HCV prevalence. In the absence of an updated national study, this analysis uses provincial data to estimate a national prevalence and the interventions needed to achieve elimination. Using a Delphi process, epidemiologic HCV data for the four provinces of Pakistan (accounting for 97% of the population) were reviewed with 21 subject-matter experts in Pakistan. Province-level estimates were inputted into a mathematical model to estimate the national HCV disease burden in the absence of intervention (Base), and if the World Health Organization (WHO) elimination targets are achieved by 2030 (80% reduction in new infections, 90% diagnosis coverage, 80% treatment coverage, and 65% reduction in mortality: WHO Elimination). An estimated 9,746,000 (7,573,000-10,006,000) Pakistanis were living with viraemic HCV as of January 1, 2021; a viraemic prevalence of 4.3% (3.3-4.4). WHO Elimination would require an annual average of 18.8 million screens, 1.1 million treatments, and 46,700 new infections prevented anually between 2022 and 2030. Elimination would reduce total infections by 7,045,000, save 152,000 lives and prevent 104,000 incident cases of hepatocellular carcinoma from 2015 to 2030. Blood surveys, programmatic data, and expert panel input uncovered more HCV infections and lower treatment numbers in the provinces than estimated using national extrapolations, demonstrating the benefits of a bottom-up approach. Screening and treatment must increase 20 times and 5 times, respectively, to curb the HCV epidemic in Pakistan and achieve elimination by 2030.

BACKGROUND: In the Northern Territory (NT) the prevalence of otitis media (OM) in young Aboriginal children living in remote communities has persisted at around 90% over the last few decades. OM-associated hearing loss can cause developmental delay and adversely impact life course trajectories. This study examined the 5-year trends in OM prevalence and quality of ear health services in remote NT communities. METHODS: A retrospective analysis was performed on de-identified clinical data for 50 remote clinics managed by the NT Government. We report a 6-monthly cascade analysis of the proportions of children 0-16 years of age receiving local guideline recommendations for surveillance, OM treatment and follow-up at selected milestones between 2014 and 2018. RESULTS: Between 6,326 and 6,557 individual children were included in the 6-monthly analyses. On average, 57% (95%CI: 56-59%) of eligible children had received one or more ear examination in each 6-monthly period. Of those examined, 36% (95%CI: 33-40%) were diagnosed with some type of OM, of whom 90% had OM requiring either immediate treatment or scheduled follow-up according to local guidelines. Outcomes of treatment and follow-up were recorded in 24% and 23% of cases, respectively. Significant decreasing temporal trends were found in the proportion diagnosed with any OM across each age group. Overall, this proportion decreased by 40% over the five years (from 43 to 26%). CONCLUSIONS: This cascade of care analysis found that ear health surveillance and compliance with otitis media guidelines for treatment and follow-up were both low. Further research is required to identify effective strategies that improve ear health services in remote settings.

In metropolitan France, estimates suggest that more than one in three adults has hypertension. Low-cost treatments are available, yet fewer than one in four hypertensive adults has a controlled level of hypertension below 140/90 mmHg. This rate is higher in other high-income countries such as Canada (65%) or Germany (52%). Using a 'cascade of care' model, that decomposes the hypertension care continuum in awareness, treatment, and control, provides a better understanding of the origins of poor control. Furthermore, the theoretical framework of intersectionality, which simultaneously considers social positions of gender, class, and ethno-racial origin, could be used to understand the complexity of the social inequalities observed in hypertension-related outcomes. In this article we conducted a critical review of the international literature to identify new lines of analyses that could be applied to examine complex inequalities in France.

We assessed the COVID-19 pandemic's impact on treatment of latent tuberculosis, and of active tuberculosis, at 3 centers in Montreal and Toronto, using data from 10 833 patients (8685 with latent tuberculosis infection, 2148 with active tuberculosis). Observation periods prior to declarations of COVID-19 public health emergencies ranged from 219 to 744 weeks, and after declarations, from 28 to 33 weeks. In the latter period, reductions in latent tuberculosis infection treatment initiation rates ranged from 30% to 66%. At 2 centers, active tuberculosis treatment rates fell by 16% and 29%. In Canada, cornerstone measures for tuberculosis elimination weakened during the COVID-19 pandemic.

BACKGROUND: Although the prevalence and mortality of hepatitis is high in the Asia-Pacific region, few studies are available on the diagnosis, treatment, and cure rates for viral hepatitis among people living with HIV in this area. This study aims to report the cascade of care (CoC) for hepatitis B (HBV) and C (HCV) among people living with HIV receiving combined antiretroviral therapy (ART). METHODS: Patients enrolled in the TREAT Asia HIV Observational Database Low Intensity Transfer (TAHOD-LITE) cohort, on ART, and with follow-up data from 2010 to 2019 were included. Patients were determined as positive for HCV or HBV co-infection if they ever tested positive for HCV antibody (anti-HCV) or HBV surface antigen (HBsAg), respectively. RESULTS: In total, 39% (8612/22 340) of the adult HIV cohort had undergone HBsAg testing, with 8% (672/8612) testing positive. HBV CoC demonstrated that 71% (474/672) of those with HBsAg positive results initiated treatment, 67% (318/474) of those on treatment had HBV DNA testing to evaluate treatment progression, and 18% (58/318) of those tested reached viral suppression. Of the cohort, 37% (8231/22 340) had anti-HCV testing, of whom 10% (779/8231) tested positive. The HCV CoC showed that 68% (526/779) of those with positive anti-HCV tests had HCV RNA tests, of whom 51% (267/526) had detectable HCV RNA. Among those with detectable HCV RNA, 65% (174/267) initiated HCV treatment. Of the 40% (69/174) who initiated HCV treatment, 90% (62/69) reached sustained virological response. CONCLUSION: Our findings identified less frequent testing in the healthcare system and limited access to treatment as gaps in the CoC for viral hepatitis. More routine HCV RNA and HBV DNA testing is required for patients with positive screening tests to identify those in need of treatment.

According to WHO goals, the elimination of Hepatitis C Virus (HCV) by 2030 requires enhancing and simplifying HCV testing. Our aim was to create a model to assess and compare different strategies for HCV testing, linkage to careâ¯and treatment among people who access harm reduction centres (HRC) and Addiction Centres in Catalonia. A decision tree model was designed to evaluate two strategies: Hepatitis C Point-of-care (POC) "test and treat", at the community versus standard-of-care (SOC), in which HCV testing was performed at community and therapy at the hospital. Both strategies were assessed separately in HRCs (6,878 users) and Addiction Centres (13,778 users). with a time horizon of 18 months. Healthcare outcomes were HCV testing, linkage to care, treatment outcomes and reinfection rate.â¯HCV testing was performed in 3,178 (46%) of the HRC users. Compared with SOC, POC increased access to treatment by 57% (63% vs. 6%). SVR rates were 64% in POC vs. 23% in SOC. Reinfection rates were 21% with POC compared to 24% with SOC. With POC, losses to follow-up were reduced by 41%. In the Addiction Centres, 12,566 users (91%) were screened using the two strategies. Compared to the SOC, POC increased access to treatment and linkage to care by 19% along with SVR at the same rate. Reinfection rates decreased by 6%. Thus, the implementation of a POC "test and treat" strategy at HRCs and Addiction Centres has shown to be an effective public health strategy to help eliminating HCV in accordance with WHO goal.

Elimination of hepatitis C virus (HCV), a leading cause of liver disease in the USA and globally, has been made possible with the advent of highly efficacious direct acting antivirals (DAAs). DAA regimens offer cure of HCV with 8-12 weeks of a well-tolerated once daily therapy. With increasingly straightforward diagnostic and treatment algorithms, HCV infection can be managed not only by specialists, but also by primary care providers. Engaging primary care providers greatly increases capacity to diagnose and treat chronic HCV and ultimately make HCV elimination a reality. However, barriers remain at each step in the HCV cascade of care from screening to evaluation and treatment. Since primary care is at the forefront of patient contact, it represents the ideal place to concentrate efforts to identify barriers and implement solutions to achieve universal HCV screening and increase curative treatment.

BACKGROUND AND AIMS: People who inject drugs (PWID) and other marginalized populations with high hepatitis C virus (HCV) infection rates represent a unique challenge for treatment initiation due to health, administrative and social barriers. We analysed the HCV cascade of care (CoC) in some vulnerable subpopulations in Madrid, Spain, when using a mobile point-of-care (PoC). METHODS: From 2019 to 2021, a mobile unit was used to screen active HCV using a linkage-to-care and two-step PoC-based strategy. Viremic participants were grouped into four subgroups: PWID, homeless individuals and people with a mental health disorder (MHD) and alcohol use disorder (AUD). Logistic regression, and Cox and Aalen's additive models were used to analyse associated factors and differences between groups. RESULTS: A prospectively recruited cohort of 214 HCV-infected individuals (73 PWID, 141 homeless, 57 with a MHD and 91 with AUD) participated in the study. The overall HCV CoC analysis found that 178 (83.1%) attended a hospital, 164 (76.6%) initiated direct-acting antiviral therapy and 141 (65.8%) completed therapy, of which 99 (95.2%) achieved sustained virological response (SVR). PWID were significantly less likely to initiate treatment, whereas individuals with AUD waited longer before starting the treatment. Both people with AUD and PWID were significantly less likely to complete HCV treatment. CONCLUSIONS: Overall, SVR was achieved in the majority of the participants treated. However, PWID need better linkage to care and treatment, whereas PWID and AUD need more support for treatment completion.

Female sex workers (FSWs) in South Africa experience a uniquely high prevalence of HIV. We describe the HIV cascade of care (CoC) in FSWs in South Africa, and explored service utilisation at sex work programmes. A cross-sectional, study enrolled FSWs across 12 sites in South Africa. Participants were recruited using chain-referral method. Inclusion criteria: ≥ 18 years, cis-gender female, sold/transacted in sex, HIV positive. 1862 HIV positive FSWs were enrolled. 92% were known positive, 87% were on antiretroviral treatment (ART). Of those on ART, 74% were virally suppressed. Younger FSWs were significantly less likely to be on ART or virally suppressed. Female sex workers using HIV services from specialised programs were 1.4 times more likely to be virally suppressed than non-program users. The pre-COVID-19 pandemic HIV CoC amongst FSWs in South Africa shows striking improvement from previous estimates, and approaches achievement of 90:90:90 goals.
