Evaluating the spatial accessibility and spatial layout optimization of HIV/AIDS healthcare services in Shandong Province, China. Sci Rep 2024; 14:11258. [PMID: 38755199 PMCID: PMC11099158 DOI: 10.1038/s41598-024-61484-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2024] [Accepted: 05/06/2024] [Indexed: 05/18/2024] Open
Abstract
Improving access to HIV/AIDS healthcare services is of great concern to government and policymakers striving to strengthen overall public health. How to reasonably allocate HIV/AIDS healthcare resources and maximize the equality of access to healthcare services across subdistrict areas has become an urgent problem to be solved. However, there is limited research on this topic in China. It is necessary to evaluate spatial accessibility to improve the accessibility and equity of HIV/AIDS healthcare services. In this study, the improved multi-modal two-step floating catchment area (2SFCA) and inverted 2SFCA (i2SFCA) methods are used to measure the spatial accessibility of HIV/AIDS healthcare services and the crowdedness of the healthcare sites in Shandong Province, China. Then, the theoretical supply and the optimal spatial distribution of resources are calculated and visualized by minimizing the accessibility gaps between demand locations. This study showed that the spatial accessibility of HIV/AIDS service resources in Shandong Province was concentrated and unevenly distributed, and the accessibility scores in the marginal areas of prefecture-level cities were significantly lower than those in other areas. Regions with a large number of doctors had significantly higher levels of spatial accessibility. The ART accessibility scores in the southwest of Shandong Province were higher than those in other regions. As the travel friction coefficient increased, the accessibility scores formed an approximately circular cluster distribution centered on the healthcare sites in geographical distribution. More ART drugs needed to be supplied in marginal areas and more doctors were needed to work on HIV/AIDS in urban areas to address the spatial distribution imbalance of HIV/AIDS healthcare services. This study profoundly analyzed the spatial accessibility of HIV/AIDS healthcare services and provided essential references for decision-makers. In addition, it gives a significant exploration for achieving the goal of equal access to HIV/AIDS healthcare services in the future.

Equity of PrEP uptake by race, ethnicity, sex and region in the United States in the first decade of PrEP: a population-based analysis. LANCET REGIONAL HEALTH. AMERICAS 2024; 33:100738. [PMID: 38659491 PMCID: PMC11041841 DOI: 10.1016/j.lana.2024.100738] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Revised: 03/25/2024] [Accepted: 03/27/2024] [Indexed: 04/26/2024]
Abstract
Background PrEP was approved for HIV prevention in the US in 2012; uptake has been slow. We describe relative equity with the PrEP Equity Ratio (PER), a ratio of PrEP-to-Need Ratios (PnRs). Methods We used commercial pharmacy data to enumerate PrEP users by race and ethnicity, sex, and US Census region from 2012 to 2021. We report annual race and ethnicity-, sex-, and region-specific rates of PrEP use and PnR, a metric of PrEP equity, to assess trends. Findings PrEP use increased for Black, Hispanic and White Americans from 2012 to 2021. By 2021, the rate of PrEP use per population was similar in Black and White populations but slightly lower among Hispanic populations. PnR increased from 2012 to 2021 for all races and ethnicities and regions; levels of PrEP use were inconsistent across regions and highly inequitable by race, ethnicity, and sex. In all regions, PnR was highest for White and lowest for Black people. Inequity in PrEP use by race and ethnicity, as measured by the PER, grew early after availability of PrEP and persisted at a level substantially below equitable PrEP use. Interpretation From 2012 to 2021, PrEP use increased among Americans, but PrEP equity for Black and Hispanic Americans decreased. The US South lagged all regions in equitable PrEP use. Improved equity in PrEP use will be not only just, but also impactful on the US HIV epidemic; persons most at-risk of acquiring HIV should have the highest levels of access to PrEP. Prevention programs should be guided by PrEP equity, not PrEP equality. Funding National Institutes of Health, Gilead Sciences.

Abstract
PURPOSE OF REVIEW Despite highly effective biomedical HIV pre-exposure prophylaxis (PrEP) options, suboptimal PrEP uptake impedes progress towards ending the epidemic in the United States of America (USA). Implementation science bridges what we know works in controlled clinical trial settings to the context and environment in which efficacious tools are intended to be deployed. In this review, we focus on strategies that target PrEP use barriers at the system or structural level, exploring the implications and opportunities in the context of the fragmented USA healthcare system. RECENT FINDINGS Task shifting could increase PrEP prescribers, but effectiveness evidence is scarce in the USA, and generally focused in urban settings. Integration of PrEP within existing healthcare infrastructure concentrates related resources, but demonstration projects rarely present the resource implications of redirecting staff. Changing the site of service via expanded telehealth could improve access to more rural populations, though internet connectivity, technology access, and challenges associated with determining biomedical eligibility remain logistical barriers for some of the highest burden communities in the USA. Finally, a tailored care navigation and coordination approach has emerged as a highly effective component of PrEP service provision, attempting to directly modify the system-level determinants of PrEP use experienced by the individual. We highlight recent advances and evidence surrounding task shifting, integration, service delivery, and tailoring. With the exception of tailored care navigation, evidence is mixed, and the downstream impact and sustainability of task shifting and care integration require further attention. To maximize PrEP outcomes, research will need to continue to examine the interplay between individuals, clinics, and the healthcare system and associated policies within which they operate.

Abstract
Multiple rural states and communities experience elevated rates of human immunodeficiency virus (HIV), often associated with diminished healthcare access and increased drug use. Though a substantial proportion of rural populations are sexual and gender minorities (SGM), little is known of this group regarding substance use, healthcare utilization, and HIV transmission behaviors. During May-July 2021, we surveyed 398 individuals across 22 rural Illinois counties. Participants included cisgender heterosexual males (CHm) and females (CHf) (n = 110); cisgender non-heterosexual males and females (C-MSM and C-WSW; n = 264); and transgender individuals (TG; n = 24). C-MSM participants were more likely to report daily-to-weekly alcohol and illicit drug use prescription medication misuse (versus CHf; aOR = 5.64 [2.37-13.41], 4.42 [1.56-12.53], and 29.13 [3.80-223.20], respectively), and C-MSM participants more frequently reported traveling to meet with romantic/sex partners. Further, more C-MSM and TG than C-WSW reported healthcare avoidance and denial due to their orientation/identity (p < 0.001 and p = 0.011, respectively); 47.6% of C-MSM and 58.3% of TG had not informed their provider about their orientation/identity; and only 8.6% of C-MSM reported ever receiving a pre-exposure prophylaxis (PrEP) recommendation. More work is needed to explore the substance use and sexual behaviors of rural SGM, as well as their healthcare interactions, to better target health and PrEP engagement campaigns.

Abstract
PURPOSE We examine how various pre-exposure prophylaxis (PrEP) accessibility measures impact the detection of PrEP shortage areas and the relation of shortage areas to social determinants of health (SDOH). METHODS Using ZIP Code Tabulation Areas (ZCTAs) in New York City as a case study, we compared 25 measures of spatial PrEP accessibility across four categories, including density, proximity, two-step floating catchment area (2SFCA), and Gaussian 2SFCA (G2SFCA). Bayesian spatial regression models were used to examine how PrEP accessibility is associated with SDOH. RESULTS Using density to measure PrEP accessibility for small areas such as ZCTAs poses challenges to statistical modeling because the measured accessibility values are highly skewed with excess zeros, leading to the necessity of using complex models such as the two-part mixture model. When G2SFCA measures are used, which account for distance decay effects and the competition from the PrEP demand side, findings on PrEP shortage area detection and the association between PrEP accessibility and SDOH were more consistent and less sensitive to spatial scales (i.e., varying from 10- to 30-minute driving). CONCLUSIONS This research adds to the nascent research on PrEP accessibility measurement and sheds light on selecting an appropriate measure to assess spatial disparities in PrEP accessibility and its associations with SDOH.

Abstract
Little is known about the effect of travel-related factors, such as mode of transportation, on retention in PrEP care, or PrEP persistence. We used data from the 2020 American Men's Internet Survey and conducted multilevel logistic regression to estimate the association between mode of transportation used for healthcare access and PrEP persistence among urban gay, bisexual, and other men who have sex with men (MSM) in the U.S. MSM using public transportation were less likely to report PrEP persistence (aOR: 0.51; 95% CI: 0.28-0.95) than MSM using private transportation. There were no significant associations between PrEP persistence and using active transportation (aOR: 0.67; 95% CI: 0.35-1.29) or multimodal transportation (aOR: 0.85; 95% CI: 0.51-1.43) compared to using private transportation. Transportation-related interventions and policies are needed to address structural barriers to accessing PrEP services and to improve PrEP persistence in urban areas.

Abstract
We sought to describe and quantify the association between HIV service organization availability, HIV burden, and HIV awareness and prevention in the 57 priority jurisdictions selected as part of the U.S. Ending the HIV Epidemic initiative. On average, jurisdictions with more per capita organizations had more people living with HIV, more individuals aware of their positive status, and more individuals prescribed PrEP (b = 0.3; 95% CI [0.2, 0.5] for each additional case per 1,000 people in the first metric, and b = 0.3; 95% CI [0.2, 0.4] and b = 0.1; 95% CI [< 0.1, 0.1], respectively, for each percentage point change in the second two metrics), accounting for jurisdiction size. Several jurisdictions were outliers in the modeled associations and may reflect comparatively better, or worse, performance than similar jurisdictions. This information can assist in evaluating resource allocation and determining whether availability translates to accessibility.

Estimating HIV Incident Diagnoses Among Men Who Have Sex With Men Eligible for Pre-exposure Prophylaxis but Not Taking It: Protocol and Feasibility Assessment of Data Sources and Methods. JMIR Res Protoc 2023; 12:e42267. [PMID: 36881450 PMCID: PMC10031441 DOI: 10.2196/42267] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2022] [Revised: 12/27/2022] [Accepted: 01/20/2023] [Indexed: 03/08/2023] Open
Abstract
BACKGROUND HIV incidence estimates are published each year for all Ending the HIV Epidemic (EHE) counties, but they are not stratified by the demographic variables highly associated with risk of infection. Regularly updated estimates of HIV incident diagnoses available at local levels are required to monitor the epidemic in the United States over time and could contribute to background incidence rate estimates for alternative clinical trial designs for new HIV prevention products. OBJECTIVE We describe methods using existing, robust data sources within areas in the United States to reliably estimate longitudinal HIV incident diagnoses stratified by race and age categories among men who have sex with other men (MSM) eligible for pre-exposure prophylaxis (PrEP) but not taking it. METHODS This is a secondary analysis of existing data sources to develop new estimates of incident HIV diagnoses in MSM. We reviewed past methods used to estimate incident diagnoses and explored opportunities to improve these estimates. We will use existing surveillance data sources and population sizes of HIV PrEP-eligible MSM estimated from population-based data sources (eg, US Census data and pharmaceutical prescription databases) to develop metropolitan statistical area-level estimates of new HIV diagnoses among PrEP-eligible MSM. Required parameters are number of new diagnoses among MSM, estimates of MSM with an indication for PrEP, and prevalent PrEP use including median duration of use; these parameters will be stratified by jurisdiction and age group or race or ethnicity. Preliminary outputs will be available in 2023, and updated estimates will be produced annually thereafter. RESULTS Data to parameterize new HIV diagnoses among PrEP-eligible MSM are available with varying levels of public availability and timeliness. In early 2023, the most recent available data on new HIV diagnoses were from the 2020 HIV surveillance report, which reports 30,689 new HIV infections in 2020, and 24,724 of them occurred in an MSA with a population of ≥500,000. Updated estimates for PrEP coverage based on commercial pharmacy claims data through February 2023 will be generated. The rate of new HIV diagnoses among MSM can be estimated from new diagnoses within each demographic group (numerator) and the total person-time at risk of diagnosis for each group (denominator) by metropolitan statistical area and year. To estimate time at risk, the person-time of individuals on PrEP or person-time after incident HIV infection but before diagnosis should be removed from stratified population size estimates of the total number of person-years with indications for PrEP. CONCLUSIONS Reliable, serial, cross-sectional estimates for rates of new HIV diagnoses for MSM with PrEP indications can serve as benchmark community estimates of failures of HIV prevention and opportunities to improve services and will support public health epidemic monitoring and alternative clinical trial designs.

Abstract
PURPOSE HIV rates are increasing in rural areas, and adolescents are disproportionately affected. HIV pre-exposure prophylaxis (PrEP) is a daily pill that is effective at preventing HIV; however, PrEP uptake among adolescents is low. PrEP is dependent on primary care providers (PCPs) prescribing it, but research has overwhelmingly sampled urban PCPs. This study compared the PrEP awareness, practices, and comfort between rural and urban family medicine physicians. METHODS A total of 256 family medicine physicians in the United States were recruited from a Qualtrics panel to complete an online cross-sectional survey between July 15 and August 9, 2022. Participants completed items assessing their demographic characteristics and PrEP awareness, practices, and comfort. A chi-square test of independence and multiple logistic regression were used to determine rural/urban differences. FINDINGS Rural family medicine physicians were less comfortable than urban family medicine physicians in providing sexual risk reduction counseling to adolescents, telling an adolescent patient their HIV test result was HIV positive, and implementing all of the PrEP clinical activities for adolescents. CONCLUSIONS Education, skill-building, and collaborative partnership interventions could improve the comfort levels of rural family medicine physicians in implementing the PrEP guidelines for their adolescent patients. Future research is needed to understand the factors that explain the differences in PrEP-related attitudes and practices between urban and rural family medicine physicians. Results from such studies could inform provider-based interventions that ultimately increase PrEP use and decrease HIV rates among rural adolescents.

Abstract
Frequent HIV testing and knowledge of HIV serostatus is the premise before timely access to HIV prevention and treatment services, but a portion of young men who have sex with men (YMSM) do not always follow up on their HIV test results after HIV testing, which is detrimental to the implementation of HIV prevention and care among this subgroup. The comprehensive evaluation of factors associated with inconsistent follow-up on HIV test results may inform relevant interventions to address this critical issue among YMSM. To this end, we conducted a cross-sectional study in Nashville, Tennessee and Buffalo, New York from May 2019 to May 2020 to assess demographic, behavioral, and psychosocial correlates of inconsistent follow-up on HIV test results among YMSM. Of the 347 participants, 27.1% (n = 94) reported inconsistent follow-up on their HIV test results. Multivariable logistic regression showed that inconsistent follow-up on HIV test results was positively associated with condomless receptive anal sex, group sex, recreational drug use before or during sex, internalized homophobia, and stress; while negatively associated with housing stability, social support, and general resilience. Future HIV prevention intervention efforts should target these modifiable determinants to enhance the follow-up on HIV test results among YMSM.

Abstract
PURPOSE Adherence to pre-exposure prophylaxis (PrEP) during periods of PrEP-indication (i.e., prevention-effective adherence) is critical for preventing HIV. We sought to describe factors associated with prevention-effective adherence trajectories among transgender women (TW) to inform PrEP implementation strategies. METHODS Using data from The LITE American Cohort (n = 728), we performed group-based multi-trajectory modeling (GBMTM) to identify clusters of TW with similar trajectories of PrEP adherence and indication, and sociodemographic, biobehavioral, and structural correlates of each trajectory. RESULTS We identified five trajectories: (1) consistent indication/no PrEP (15.3%), (2) initial indication/no PrEP (47.1%), (3) declining indication/discontinued PrEP (9.5%), (4) consistent indication/PrEP adherent (18.5%), and (5) increasing indication/initiated PrEP (9.6%). TW diagnosed with an STI were more likely to follow a consistent indication/no PrEP trajectory compared to consistent indication/PrEP adherent trajectory (adjusted Relative Risk Ratio [aRRR], 2.54; 95% confidence interval [CI], 1.16-5.57). TW who experienced homelessness were more likely to follow PrEP discontinuation and initiation trajectories relative to PrEP adherence (aRRR, 2.71; 95% CI, 1.10-6.70 and 2.83; 95% CI, 1.13-7.05, respectively). CONCLUSIONS Over a quarter of TW followed trajectories suggestive of prevention-effective adherence, while 15% did not initiate PrEP despite consistent indication. Findings highlight missed opportunities for PrEP engagement at STI diagnosis and suggest structural interventions addressing housing instability may improve prevention-effective adherence among TW.
