Abstract
BACKGROUND Housing and employment are key factors in the health and well-being of people with HIV (PWH). Patient navigation programs to improve housing and employment show success in achieving viral suppression. Replicating patient navigation interventions to improve population health is needed. Understanding costs associated with patient navigation is a key next step. Therefore, the purpose of this study is to describe the costs associated with delivering patient navigator interventions in two different organizations to improve housing and employment for PWH. METHODS We conducted a cost analysis of two models of patient navigation. Costs were collected from two sites' payroll, invoices, contracts, and receipts. Pre-implementation and implementation costs and utilization of service costs are presented. Potential reimbursement costs were calculated based on salaries from the Department of Labor. RESULTS The health clinic's pre-implementation costs were higher ($169,133) than the health department's ($22,018). However, costs of patient navigation during the 2-year intervention were similar between health clinic and health department ($264,985 and $232,923, respectively). The health clinic reported more total time spent with clients (16,013.7 hours) than the health department (1,883.8 hours). The costs per additional person suppressed were $20,632 versus $37,810 for the health department and health clinic, respectively, which are lower than the average lifetime cost of HIV treatment. DISCUSSION Replicability and scalability of a patient navigation intervention are possible in both health clinic and health department settings. Each site had specific costs, client needs, and other factors that required adaptations to successfully implement the intervention. Future programs should consider tailoring costs to site-specific factors to improve outcomes. Policymakers and public health officials should consider using these results to improve planning and investment in HIV treatment and prevention interventions.

Abstract
Experiencing housing instability, food insecurity, and financial stress can negatively impact retention in care and treatment adherence for people living with HIV. Expanding services that support socioeconomic needs could help improve HIV outcomes. Our objective was to investigate barriers, opportunities, and costs of expanding socioeconomic support programs. Semi-structured interviews were conducted with organizations serving U.S. Ryan White HIV/AIDS Program clients. Costs were estimated from interviews, organization documents, and city-specific wages. Organizations reported complex patient, organization, program, and system challenges as well as several opportunities for expansion. The average one-year per-person cost for engaging new clients was $196 for transportation, $612 for financial aid, $650 for food aid, and $2498 for short-term housing (2020 USD). Understanding potential expansion costs is important for funders and local stakeholders. This study provides a sense of magnitude for costs to scale-up programs to better meet socioeconomic needs of low-income patients living with HIV.

Abstract
The purpose of this scoping review is to establish the state of the art on economic evaluations in the field of HIV/STI prevention in high-income countries with concentrated epidemic settings and to assess what we know about the cost-effectiveness of different measures. We reviewed economic evaluations of HIV/STI prevention measures published in the Web of Science and Cost-Effectiveness Registry databases. We included a total of 157 studies focusing on structural, behavioural, and biomedical interventions, covering a variety of contexts, target populations and approaches. The majority of studies are based on mathematical modelling and demonstrate that the preventive measures under scrutiny are cost-effective. Interventions targeted at high-risk populations yield the most favourable results. The generalisability and transferability of the study results are limited due to the heterogeneity of the populations, settings and methods involved. Furthermore, the results depend heavily on modelling assumptions. Since evidence is unequally distributed, we discuss implications for future research.

Comprehensive approach to HIV/AIDS testing and linkage to treatment among men who have sex with men in Curitiba, Brazil. PLoS One 2021; 16:e0249877. [PMID: 33970929 PMCID: PMC8110178 DOI: 10.1371/journal.pone.0249877] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2020] [Accepted: 03/29/2021] [Indexed: 11/25/2022] Open
Abstract
Introduction The Curitiba (Brazil)-based Project, A Hora é Agora (AHA),
evaluated a comprehensive HIV control strategy among men who have sex with
men (MSM) aimed at expanding access to HIV rapid testing and linking
HIV-positive MSM to health services and treatment. AHA’s approach included
rapid HIV Testing Services (HTC) in one mobile testing unit (MTU); a local,
gay-led, non-governmental organization (NGO); an existing government-run
health facility (COA); and Internet-based HIV self-testing. The objectives
of the paper were to compare a) number of MSM tested in each strategy, its
positivity and linkage; b) social, demographic and behavioral
characteristics of MSM accessing the different HTC and linkage services; and
c) the costs of the individual strategies to diagnose and link MSM to
services. Methods We used data for 2,681 MSM tested at COA, MTU and NGO from March 2015 to
March 2017. This is a cross sectional comparison of the demographics and
behavioral factors (age group, race/ethnicity, education, sexually
transmitted diseases, knowledge of AHA services and previous HIV test).
Absolute frequencies, percentage distributions and confidence intervals for
the percentages were used, as well as unilateral statistical tests. Results and discussion AHA performed 2,681 HIV tests among MSM across three in-person strategies:
MTU, NGO, and COA; and distributed 4,752 HIV oral fluid tests through the
self-testing platform. MTU, NGO and COA reported 365 (13.6%) HIV positive
diagnoses among MSM, including 28 users with previous HIV diagnosis or on
antiretroviral treatment for HIV. Of these, 89% of MSM were eligible for
linkage-to-care services. Linkage support was accepted by 86% of positive
MSM, of which 66.7% were linked to services in less than 90 days. The MTU
resulted in the lowest cost per MSM tested ($137 per test), followed by
self-testing ($247). Conclusions AHA offered MSM access to HTC through innovative strategies operating in
alternative sites and schedules. It presented the Curitiba HIV/AIDS
community the opportunity to monitor HIV-positive MSM from diagnosis to
treatment uptake. Self-testing emerged as a feasible strategy to increase
MSM access to HIV-testing through virtual tools and anonymous test kit
delivery and pick-up. Cost per test findings in both the MTU and
self-testing support expansion to other regions with similar epidemiological
contexts.

Outcomes and costs of publicly funded patient navigation interventions to enhance HIV care continuum outcomes in the United States: A before-and-after study. PLoS Med 2021; 18:e1003418. [PMID: 33983925 PMCID: PMC8118317 DOI: 10.1371/journal.pmed.1003418] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/18/2019] [Accepted: 03/29/2021] [Indexed: 11/18/2022] Open
Abstract
BACKGROUND In the United States, patients with HIV face significant barriers to linkage to and retention in care which impede the necessary steps toward achieving the desired clinical outcome of viral suppression. Individual-level interventions, such as patient navigation, are evidence based, effective strategies for improving care engagement. In addition, use of surveillance and clinical data to identify patients who are not fully engaged in care may improve the effectiveness and cost-effectiveness of these programs. METHODS AND FINDINGS We employed a pre-post design to estimate the outcomes and costs, from the program perspective, of 5 state-level demonstration programs funded under the Health Resources and Services Administration's Special Projects of National Significance Program (HRSA/SPNS) Systems Linkages Initiative that employed existing surveillance and/or clinical data to identify individuals who had never entered HIV care, had fallen out of care, or were at risk of falling out of care and navigation strategies to engage patients in HIV care. Outcomes and costs were measured relative to standard of care during the first year of implementation of the interventions (2013 to 2014). We followed patients to estimate the number and proportion of additional patients linked, reengaged, retained, and virally suppressed by 12 months after enrollment in the interventions. We employed inverse probability weighting to adjust for differences in patient characteristics across programs, missing data, and loss to follow-up. We estimated the additional costs expended during the first year of each intervention and the cost per outcome of each intervention as the additional cost per HIV additional care continuum target achieved (cost per patient linked, reengaged, retained, and virally suppressed) 12 months after enrollment in each intervention. In this study, 3,443 patients were enrolled in Louisiana (LA), Massachusetts (MA), North Carolina (NC), Virginia (VA), and Wisconsin (WI) (147, 151, 2,491, 321, and 333, respectively). Patients were a mean of 40 years old, 75% male, and African American (69%) or Caucasian (22%). At baseline, 24% were newly diagnosed, 2% had never been in HIV care, 45% had fallen out of care, and 29% were at risk of falling out of care. All 5 interventions were associated with increases in the number and proportion of patients with viral suppression [percent increase: LA = 90.9%, 95% confidence interval (CI) = 88.4 to 93.4; MA = 78.1%, 95% CI = 72.4 to 83.8; NC = 47.5%, 95% CI = 45.2 to 49.8; VA = 54.6, 95% CI = 49.4 to 59.9; WI = 58.4, 95% CI = 53.4 to 63.4]. Overall, interventions cost an additional $4,415 (range = $3,746 to $5,619), $2,009 (range = $1,516 to $2,274), $920 (range = $627 to $941), $2,212 (range = $1,789 to $2,683), and $3,700 ($2,734 to $4,101), respectively per additional patient virally suppressed. The results of this study are limited in that we did not have contemporaneous controls for each intervention; thus, we are only able to assess patients against themselves at baseline and not against standard of care during the same time period. CONCLUSIONS Patient navigation programs were associated with improvements in engagement of patients in HIV care and viral suppression. Cost per outcome was minimized in states that utilized surveillance data to identify individuals who were out of care and/or those that were able to identify a larger number of patients in need of improvement at baseline. These results have the potential to inform the targeting and design of future navigation-type interventions.

Abstract
OBJECTIVES Ending the HIV epidemic requires innovative use of data for intelligent decision-making from surveillance through treatment. This study sought to examine the usefulness of using linked integrated PLWH health data to predict PLWH's future HIV care status and compare the performance of machine-learning methods for predicting future HIV care status for SC PLWH. DESIGN We employed supervised machine learning for its ability to predict PLWH's future care status by synthesizing and learning from PLWH's existing health data. This method is appropriate for the nature of integrated PLWH data because of its high volume and dimensionality. METHODS A data set of 8888 distinct PLWH's health records were retrieved from an integrated PLWH data repository. We experimented and scored seven representative machine-learning models including Bayesian Network, Automated Neural Network, Support Vector Machine, Logistic Regression, LASSO, Decision Trees and Random Forest to best predict PLWH's care status. We further identified principal factors that can predict the retention-in-care based on the champion model. RESULTS Bayesian Network (F = 0.87, AUC = 0.94, precision = 0.87, recall = 0.86) was the best predictive model, followed by Random Forest (F = 0.78, AUC = 0.81, precision = 0.72, recall = 0.85), Decision Tree (F = 0.76, AUC = 0.75, precision = 0.70, recall = 0.82) and Neural Network (cluster) (F = 0.75, AUC = 0.71, precision = 0.69, recall = 0.81). CONCLUSION These algorithmic applications of Bayesian Networks and other machine-learning algorithms hold promise for predicting future HIV care status at the individual level. Prediction of future care patterns for SC PLWH can help optimize health service resources for effective interventions. Predictions can also help improve retention across the HIV continuum.

Abstract
BACKGROUND The patient-centered HIV care model (PCHCM) is an evidence-informed structural intervention that integrates community-based pharmacists with primary medical providers to improve rates of HIV viral suppression. This report assesses the costs and cost-effectiveness of the PCHCM. SETTING Patient-centered HIV care model. METHODS Three project sites, each composed of a medical clinic and 1 or 2 community-based HIV-specialized pharmacies, were included in the analyses. PCHCM required patient data sharing between medical providers and pharmacists and collaborative therapy-related decision making. Intervention effectiveness was measured as the incremental number of patients virally suppressed (HIV RNA <200 copies/mL at the last test in a 12-month measurement period). Microcosting direct measurement methods were used to estimate intervention costs. The cost per patient, cost per patient visit, and incremental cost per patient virally suppressed were calculated from the health care providers' perspective. Additionally, the number of HIV transmissions averted, lifetime HIV treatment cost saved, quality-adjusted life years (QALYs) saved, and cost per QALY saved were calculated from the societal perspective, using standard methods and reported values from the published literature. RESULTS Overall, the PCHCM annual intervention cost for the 3 project sites was $226,741. The average cost per patient, cost per patient visit, and incremental cost per patient virally suppressed were $813, $48, and $5,039, respectively. The intervention averted 2.75 HIV transmissions and saved 12.22 QALYs and nearly $1.28 million in lifetime HIV treatment costs. The intervention was cost saving overall and at each project site. CONCLUSIONS The PCHCM can be delivered at a relatively low cost and is a cost-saving intervention to assist patients in achieving viral suppression and preventing HIV transmission.

Abstract
In 2017, the Health Resources and Services Administration's HIV/AIDS Bureau funded an Evaluation Center (EC) and a Coordinating Center for Technical Assistance (CCTA) to oversee the rapid implementation of 11 evidence-informed interventions at 26 HIV care and treatment providers across the U.S. This initiative aims to address persistent gaps in HIV-related health outcomes emerging from social determinants of health that negatively impact access to and retention in care. The EC adapted the Conceptual Model of Implementation Research to develop a Hybrid Type III, multi-site mixed-methods evaluation, described in this paper. The results of the evaluation will describe strategies associated with uptake, implementation outcomes, as well as HIV-related health outcomes for clients engaged in the evidence-informed interventions. This approach will allow us to understand in detail the processes that sites undergo to implement these important intervention strategies for high priority populations.

Abstract
OBJECTIVE We sought to evaluate, which combinations of HIV prevention and care activities would have the greatest impact towards reaching the US Ending the HIV Epidemic (EHE) plan goals of HIV incidence reduction. DESIGN A stochastic network-based HIV transmission model for men who have sex with men (MSM), calibrated to surveillance estimates in the Atlanta area, a focal EHE jurisdiction. METHODS Model scenarios varied HIV screening rates under different assumptions of how HIV-negative MSM would be linked to PrEP initiation, and rates of HIV care linkage and retention for those screening positive. RESULTS A ten-fold relative increase in HIV screening rates (to approximately biannual screening for black and Hispanic MSM and quarterly for white MSM) would lead to 43% of infections averted if integrated with PrEP initiation. Improvements focused only on black MSM would achieve nearly the same outcome (37% of infections averted). Improvements to HIV care retention would avert 41% of infections if retention rates were improved ten-fold. If both screening and retention were jointly improved ten-fold, up to 74% of cumulative infections would be averted. Under this scenario, it would take 4 years to meet the 75% EHE goal and 12 years to meet the 90% goal for Atlanta MSM. CONCLUSION Reaching the EHE 75% incidence reduction goals by their target dates will require immediate and substantial improvements in HIV screening, PrEP, and ART care retention. Meeting these EHE goals in target jurisdictions like Atlanta will be possible only by addressing the HIV service needs of black MSM.

Abstract
To address gaps in the cost literature by estimating the cost of delivering an evidence-based HIV risk reduction intervention for HIV-serodiscordant, heterosexual, African American couples (Eban II) and calculating the cost-effective thresholds at three participating sites. The cost, cost-saving, and cost-effectiveness thresholds for Eban II were calculated using standard methods. The analytic time period was from July 1 to September 31, 2014. Total costs for 3 months of program implementation were from $13,747 to $25,937, with societal costs ranging from $5632 to $17,008 and program costs ranging from $8115 to $14,122. The costs per participant were from $1621 to $2160; the cost per session (per participant) ranged from $147 to $196. Sites had achievable cost-saving thresholds, which were all less than one for the 3-month costing timeframe.

Abstract
To improve health outcomes in people living with HIV, adoption of evidence-based interventions (EBIs) using effective and transferable implementation strategies to optimise the delivery of healthcare is needed. ViiV Healthcare's Positive Pathways initiative was established to support the UNAIDS 90-90-90 goals. A compendium of EBIs was developed to address gaps within the HIV care continuum, yet it was unknown whether efforts existed to adapt and implement these EBIs across diverse clinical contexts. Therefore, this review sought to report on the use of implementation science in adapting HIV continuum of care EBIs. A systematic literature review was undertaken to summarise the evaluation of implementation and effectiveness outcomes, and report on the use of implementation science in HIV care. Ten databases were reviewed to identify studies (time-period: 2013-2018; geographic scope: United States, United Kingdom, France, Germany, Italy, Spain, Canada, Australia and Europe; English only publications). Studies were included if they reported on people living with HIV or those at risk of acquiring HIV and used interventions consistent with the EBIs. A broad range of study designs and methods were searched, including hybrid designs. Overall, 118 publications covering 225 interventions consistent with the EBIs were identified. These interventions were evaluated on implementation (N = 183), effectiveness (N = 81), or both outcomes (N = 39). High variability in the methodological approaches was observed. Implementation outcomes were frequently evaluated but use of theoretical frameworks was limited (N = 13). Evaluations undertaken to assess effectiveness were inconsistent, resulting in a range of measures. This review revealed extensive reporting on implementation science as defined using evaluation outcomes. However, high variability was observed in how implementation outcomes and effectiveness were defined, quantified, and reported. A more specific and consistent approach to conducting and reporting on implementation science in HIV could facilitate achievement of UNAIDS 90-90-90 targets.

An Electronic Pre-Exposure Prophylaxis Initiation and Maintenance Home Care System for Nonurban Young Men Who Have Sex With Men: Protocol for a Randomized Controlled Trial. JMIR Res Protoc 2019; 8:e13982. [PMID: 31199326 PMCID: PMC6592500 DOI: 10.2196/13982] [Citation(s) in RCA: 34] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2019] [Revised: 05/01/2019] [Accepted: 05/02/2019] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND Pre-exposure prophylaxis (PrEP) is highly efficacious for preventing HIV but has not yet been brought to scale among at-risk persons. In several clinical trials in urban areas, technology-based interventions have shown a positive impact on PrEP adherence. In rural and small-town areas in the United States, which often do not have geographically proximal access to PrEP providers, additional support may be needed. This may be particularly true for younger persons who are more likely to face multiple barriers to accessing PrEP services. Home-based care, accomplished through a tailored mobile phone app, specimen self-collection (SSC), and interactive video consultations, could increase both PrEP initiation and persistence in care. OBJECTIVE The goal of this study is to assess the initiation and persistence in PrEP care for those randomized to a home-care intervention (electronic PrEP, ePrEP) relative to those assigned to the standard of care (control) condition. We will conduct additional assessments, including quantitative and qualitative analyses, to contextualize trial results and facilitate scale-up. METHODS This 2-arm, randomized controlled trial will enroll young men who have sex with men (YMSM) aged between 18 and 24 years from rural areas of Georgia, Mississippi, and North Carolina. The trial will seek to recruit a diverse sample, targeting 50% participation among highly impacted groups of black or Latino men who have sex with men. Intervention participants will receive a study app that incorporates a messaging platform, a scheduling and milestone-based tracking system for PrEP care progress, electronic behavioral surveys, and interactive video consultations with a clinician. Complemented by SSC kits mailed to laboratories for standard PrEP-related monitoring, the ePrEP system will allow participants to access PrEP care without leaving their homes. YMSM randomized to the control condition will receive a listing of nearest local PrEP providers to receive standard PrEP care. Both groups will complete quarterly electronic surveys. The primary outcome, assessed at 6 and 12 months after randomization, will be the difference in the proportion of intervention versus control participants that achieve protective levels of the active metabolite of oral PrEP (tenofovir diphosphate in dried blood spots). RESULTS Enrollment will begin in May 2019, with study completion in 2022. CONCLUSIONS This trial will determine whether home PrEP care provided through an app-based platform is an efficacious means of expanding access to PrEP care for a diverse group of YMSM in rural and small-town areas of the United States.

Abstract
Linkage to HIV medical care and on-going engagement in HIV medical care are vital for ending the HIV epidemic. However, little is known about the cost-utility of HIV linkage, re-engagement and retention (LRC) in care programs. This paper presents the cost-utility analysis of Access to Care, a national HIV LRC program. Using standard methods from the US Panel on Cost-Effectiveness in Health and Medicine, we calculated the cost-utility ratio. Seven Access to Care programs were cost-effective and two were cost-saving. This study adds to a small but growing body of evidence to support the cost-effectiveness of LRC programs.

Abstract
Competing needs pose barriers to engagement in HIV medical care. Mixed methods were used to explore and describe the needs of participants enrolled in Access to Care, a national HIV linkage, retention and re-engagement in care (LRC) program that served people living with HIV who knew their status but were not engaged in care. When asked to prioritize their most urgent needs, participants reported housing or shelter (31%), HIV medical services (24%), and employment (8%). When we assessed the HIV continuum of care by needs status, we found no significant differences in linkage, retention, or viral suppression between participants with and without basic needs. Qualitative interviews with program staff contextualized the barriers to HIV medical care faced by participants and explored the strategies used by LRC programs to address participant needs. Study findings will be of use to future programs and have implications for HIV policy, in particular the implementation of the National HIV/AIDS Strategy (2015-2020).

Abstract
BACKGROUND Understanding the flow of patients through the continuum of HIV care is critical to determine how best to intervene so that the proportion of HIV-infected persons who are on antiretroviral treatment and virally suppressed is as large as possible. METHODS Using immunological and virological data from the Centers for Disease Control and Prevention and the North American AIDS Cohort Collaboration on Research and Design from 2009 to 2012, we estimated the distribution of time spent in and dropout probability from each stage in the continuum of HIV care. We used these estimates to develop a queueing model for the expected number of patients found in each stage of the cascade. RESULTS HIV-infected individuals spend an average of about 3.1 months after HIV diagnosis before being linked to care, or dropping out of that stage of the continuum with a probability of 8%. Those who link to care wait an additional 3.7 months on average before getting their second set of laboratory results (indicating engagement in care) or dropping out of care with probability of almost 6%. Those engaged in care spent an average of almost 1 year before achieving viral suppression on antiretroviral therapy or dropping out with average probability 13%. For patients who achieved viral suppression, the average time suppressed on antiretroviral therapy was an average of 4.5 years. CONCLUSIONS Interventions should be targeted to more rapidly identifying newly infected individuals, and increasing the fraction of those engaged in care that achieves viral suppression.

Abstract
Persons diagnosed with HIV but not retained in HIV medical care accounted for the majority of HIV transmissions in 2009 in the United States (US). There is an urgent need to implement and disseminate HIV retention in care programs; however little is known about the costs associated with implementing retention in care programs. We assessed the costs and cost-saving thresholds for seven Retention in Care (RiC) programs implemented in the US using standard methods recommended by the US Panel on Cost-effectiveness in Health and Medicine. Data were gathered from accounting and program implementation records, entered into a standardized RiC economic analysis spreadsheet, and standardized to a 12 month time frame. Total program costs for from the societal perspective ranged from $47,919 to $423,913 per year or $146 to $2,752 per participant. Cost-saving thresholds ranged from 0.13 HIV transmissions averted to 1.18 HIV transmission averted per year. We estimated that these cost-saving thresholds could be achieved through 1 to 16 additional person-years of viral suppression. Across a range of program models, retention in care interventions had highly achievable cost-saving thresholds, suggesting that retention in care programs are a judicious use of resources.
