Using audience segmentation to identify implementation strategies to improve PrEP uptake among at-risk cisgender women: a mixed-methods study protocol.

BACKGROUND: In the USA, 19% of new HIV infections occur among cisgender women (cis women); however, only 10% of eligible cis women have been prescribed pre-exposure prophylaxis (PrEP) for the prevention of HIV infection (an evidence-based intervention). A fundamental challenge for expanding HIV prevention to cis women is ensuring implementation strategies are tailored to the various healthcare settings in which cis women seek care and the heterogeneous providers nested within these settings. This project's specific aims are to (1) explore clinician-level characteristics and organizational climate factors that are related to variability in adoption of PrEP service delivery as an evidence-based intervention for cis women; (2) identify latent audience segments of women's health providers as the related to PrEP acceptability, adoption, and maintenance and analyze demographic correlates of these segments; and (3) identify audience segment-specific implementation strategies to facilitate the adoption of PrEP as an evidence-based intervention among at-risk cis women. METHODS: Using the i-PARIHS framework, this mixed-methods study examines three domains for guiding audience segmentation to facilitate PrEP implementation for cis women: innovation (degree of fit with existing practices, usability), recipient beliefs and knowledge and context factors (organizational culture, readiness for change), needs to determine appropriate facilitation methods. To achieve aim 1, qualitative interviews will be conducted with PrEP-eligible cis women, women's health providers, and other key stakeholders. Aim 2 will consist of a quantitative survey among 340 women's health providers. Latent class analysis will be used to facilitate audience segmentation. To achieve aim 3, a panel of 5-8 providers for each audience segment will meet and engage in iterative discussions guided by Fernandez's implementation mapping to identify (1) implementation outcomes and performance objectives, determinants, and change objectives and (2) determine and refine of implementation strategies for each audience segment. DISCUSSION: This exploratory mixed methods study will provide an empirical foundation to inform the development implementations strategies aimed at increasing PrEP delivery to cis women among heterogenous groups of providers.

Standing genetic variation as a potential mechanism of novel cave phenotype evolution in the freshwater isopod, Asellus aquaticus.

Novel phenotypes can come about through a variety of mechanisms including standing genetic variation from a founding population. Cave animals are an excellent system in which to study the evolution of novel phenotypes such as loss of pigmentation and eyes. Asellus aquaticus is a freshwater isopod crustacean found in Europe and has both a surface and a cave ecomorph which vary in multiple phenotypic traits. An orange eye phenotype was previously revealed by F2 crosses and backcrosses to the cave parent within two examined Slovenian cave populations. Complete loss of pigmentation, both in eye and body, is epistatic to the orange eye phenotype and therefore the orange eye phenotype is hidden within the cave populations. Our goal was to investigate the origin of the orange eye alleles within the Slovenian cave populations by examining A. aquaticus individuals from Slovenian and Romanian surface populations and Asellus aquaticus infernus individuals from a Romanian cave population. We found orange eye individuals present in lab raised surface populations of A. aquaticus from both Slovenia and Romania. Using a mapping approach with crosses between individuals of two surface populations, we found that the region known to be responsible for the orange eye phenotype within the two previously examined Slovenian cave populations was also responsible within both the Slovenian and the Romanian surface populations. Complementation crosses between orange eye Slovenian and orange eye Romanian surface individuals suggest that the same gene is responsible for the orange eye phenotype in both surface populations. Additionally, we observed a low frequency phenotype of eye loss in crosses generated between the two surface populations and also in the Romanian surface population. Finally, in a cave population from Romania, A. aquaticus infernus, we found that the same region is also responsible for the orange eye phenotype as the Slovenian cave populations and the Slovenian and Romanian surface populations. Therefore, we present evidence that variation present in the cave populations could originate from standing variation present in the surface populations and/or transgressive hybridization of different surface phylogenetic lineages rather than de novo mutations.

Two Models for Increasing the Scope and Activities of Human Immunodeficiency Virus Partner Services Programs: Preliminary Findings From the Fast Track Project.

BACKGROUND: We sought to develop a novel strategy for expanding an existing human immunodeficiency virus (HIV) partner services (PS) model to provide comprehensive sexual health services, including sexually transmitted infection testing, a virtual telemedicine visit, and access to immediate start medication (antiretroviral treatment, preexposure or postexposure prophylaxis). Fast Track was a National Institutes of Health-funded implementation science trial in New York City to pilot and refine the new strategy, and examine its feasibility, acceptability, and impact. METHODS: Over the course of 1 year, health department staff collaborated with the academic research team to develop Fast Track protocols and workflows, create a cloud-based database to interview and track patients, and train disease intervention specialists to deliver the new program. The initial field-based program (Fast Track 1.0) was piloted March to December 2019. A modified telephone-based program (Fast Track 2.0) was developed in response to COVID-19 pandemic constraints and was piloted August 2020 to March 2021. RESULTS: These 2 pilots demonstrate the feasibility and acceptability of integrating comprehensive sexual health services into HIV PS programs. Disease intervention specialists were successfully trained to conduct comprehensive sexual health visits, and clients reported that the availability of comprehensive sexual health services made them more willing to engage with PS. Key lessons for scale-up include managing collaboration with a licensed provider, navigating technical and technological issues, and challenges in client engagement and retention. CONCLUSIONS: The success of this integrated strategy suggests that telehealth visits may be a critical gateway to care engagement for PS clients. This model is an innovative strategy for increasing engagement with HIV testing, prevention, and treatment for underserved populations.

Medical avoidance among marginalized groups: the impact of the COVID-19 pandemic.

Medical avoidance is common among U.S. adults, and may be emphasized among members of marginalized communities due to discrimination concerns. In the current study, we investigated whether this disparity in avoidance was maintained or exacerbated during the onset of the COVID-19 pandemic. We assessed the likelihood of avoiding medical care due to general-, discrimination-, and COVID-19-related concerns in an online sample (N = 471). As hypothesized, marginalized groups (i.e., non-White race, Latinx/e ethnicity, non-heterosexual sexual orientation, high BMI) endorsed more general- and discrimination-related medical avoidance than majoritized groups. However, marginalized groups were equally likely to seek COVID-19 treatment as majoritized groups. Implications for reducing medical avoidance among marginalized groups are discussed.

Parallel reductions in anxiety and HIV-related worry among pre-exposure prophylaxis (PrEP) users over time.

OBJECTIVE: The threat of HIV has been proposed as a major contributing factor to the disproportionately higher rates of anxiety among gay and bisexual men compared to their heterosexual counterparts. The current study examined 12-month trajectories of anxiety symptoms and concomitant HIV-related worry among a cohort of preexposure prophylaxis (PrEP) users, compared to a comparison cohort who were not taking PrEP. METHOD: SPARK was a community-based PrEP demonstration project conducted between February 2014 and May 2017. Self-report anxiety and worry data were collected from PrEP patients (n = 300) quarterly, and from non-PrEP patients (n = 131) at baseline, 3, and 12 months. We ran a series of unconditional latent growth curve models (LGCMs) to examine changes in anxiety and HIV worry over the 12-month study period, followed by parallel process LGCMs to examine the association between both intercepts and growth factors, adjusting for demographic factors. RESULTS: In a parallel process model, both an association between baseline levels of HIV worry and anxiety decreases in both variables over time among PrEP users but not among non-PrEP users. Additionally, a multigroup analysis was conducted, restricting both groups to 3 time points, and forcing a comparison of slopes between the 2 groups. This analysis revealed that there was no difference in the anxiety slopes between the 2 cohorts. However, the HIV worry slope remained significantly different among the PrEP cohort compared to the non-PrEP cohort. CONCLUSIONS: These data provide some of the first quantitative evidence for the potential of PrEP to reduce both HIV worry and anxiety symptoms. Emphasizing positive mental health "side effects" of PrEP may be a strategy for engaging priority populations in biomedical HIV prevention.

Clinic-Level Strategies for Mitigating Structural and Interpersonal HIV Pre-Exposure Prophylaxis Stigma.

Uptake of and persistence on pre-exposure prophylaxis (PrEP) in the United States have been limited. The potential of new PrEP modalities to increase access will be hindered if underlying structural and interpersonal barriers-including, insurance coverage, initiation and maintenance clinical protocols, provider bias, stigma, and lack of trust in health care-are not adequately addressed. We conducted in-person and telephone-based recorded interviews with 32 US-based clinical and nonclinical PrEP providers spanning the PrEP implementation continuum (clinicians, counselors, and support staff). Providers were recruited at biomedical HIV prevention conferences and networks to explore barriers to and strategies for PrEP implementation. Providers provided care to clients spanning adolescents to adulthood and a variety of genders across all geographic regions of the United States. To directly mitigate stigma, providers called for clinic-level interventions to normalize and universalize PrEP education and services, counseling and other services that center patients' lived experiences and circumstance, staffing and community engagement models that value patients, and implementation of specific programs and processes that facilitate access to services. To address disparities in access, PrEP implementation should acknowledge the interconnectedness of stigma and structural barriers to care.

Changes in Utilization of Birth Control and PrEP During COVID-19 in the USA: A Mixed-Method Analysis.

In the USA, the COVID-19 pandemic has created challenges beyond the direct consequences of the infection. Because of shifting resources in response to need, many domains within the healthcare sector unrelated to COVID-19 have had interrupted abilities to provide care. In the current study, we focus on preventative sexual health care during the pandemic. In a sample of 511 (mean age = 27.7) people, we examined quantitative data regarding continuation and discontinuation of birth control and PrEP during the pandemic, along with qualitative data illustrating the underlying reasons for participants' (dis)continuation. Results showed that most (92.5%) of birth control users reported continuation of their birth control, with the predominant reasons reported being use for health reasons, long-acting reversible contraceptive use, access to remote healthcare services, and increased vigilance over pregnancy prevention. Conversely, around half (52.6%) of PrEP-using participants reported already discontinuing or planning to discontinue their PrEP regimen. Temporary abstinence and concerns about accessing in-person health care were the predominant reasons for PrEP discontinuation. These results have implications for both researchers and sexual healthcare providers. Disruptions to preventative sexual health care should be considered in ongoing research about patient needs, and healthcare providers may wish to consider particular challenges faced by PrEP users concerning re-start and continuation.

How Can I Get COVID?: Understanding Differences in American Heterosexual and Sexual Minority Men's Risk Perception.

Men are more vulnerable to COVID-19 infections compared to women, but their risk perceptions around COVID-19 are persistently lower. Further, men often engage in less health promotion behavior because self-care in this capacity is seen as weak or less masculine. This combination has consequences for mortality; thus, a better understanding of men's COVID-19 cognitions and individual difference factors is critical. In a web-based survey conducted during the beginning stages of the pandemic in the U.S., we collected risk perceptions of various sexual and non-sexual behaviors from heterosexual (n = 137) and gay/bisexual men (n = 108). There were no significant sexual orientation differences for perceptions of COVID-19 risk from routine activities or in overall risk estimates. However, gay/bisexual men did report engaging in more precautionary behavior while socializing (i.e., masking, social distancing) and reported higher risk perceptions than did heterosexual men for nearly all intimate and sexual activities. A more nuanced understanding of cognitions around COVID-19 is needed to better understand motivation for-and especially motivation against-pursuing vaccinations and continuing precautionary behavior.

Single Bisexual Men's and Women's Perceptions of Acceptance in the LGBTQ Community.

In recent years, sociocultural shifts in the U.S. have cast a positive light on the LGBTQ community, presumably providing benefits to sexual and gender minorities. Using a sample of single lesbian, gay, and bisexual men and women (N= 924) collected from a 2016 survey in the U.S., we assess bisexual people's attitudes about the "LGBTQ community", as well as how others in the community - gay men and lesbian women - view bisexuals. We also examine contexts in which bisexual people feel they are unable to share their sexual identities. Descriptive analyses revealed that while many bisexual people feel they need to hide their sexual identity in most contexts, the majority of bisexual men and women feel "mostly" to "near total acceptance" in the LGBTQ community. Thus, while bisexual people do experience stigma-related stress, findings suggest a promising shift for bisexual people's lives in terms of drawing resources and support from the larger LGBTQ community.

Behavioral and social science research to support accelerated and equitable implementation of long-acting preexposure prophylaxis.

PURPOSE OF REVIEW: The sociobehavioral research agenda for HIV prevention urgently needs to progress beyond research on end user preferences to examine how to best support patient access, engagement, and choice in the rollout of long-acting modalities. We outline critical challenges for an era of choice in biomedical prevention that could benefit from the rigorous application of sociobehavioral research methods. RECENT FINDINGS: Research in three areas could accelerate implementation of long-acting antiretrovirals for prevention: integrating dual process models into research on patient decision-making and behavior; identifying strategies that mitigate against unconscious and implicit biases in provider decision-making and behavior; and developing tools to support patient-centered communication that incorporate research in both of the first two areas. SUMMARY: We encourage the development of dual process models and measures to better understand patient behavior, including behavior related to initiating biomedical prevention, choice of prevention strategy, switching among strategies, and discontinuation. Second, there is the need to develop intervention research that targets provider behavior. Finally, we call for research to inform patient-centered communication tools that integrate an understanding of affective drivers of preexposure prophylaxis (PrEP) decision-making and protect against implicit bias in provider recommendations related to PrEP.

Psychological threat avoidance as a barrier to HIV testing in gay/bisexual men.

The present study examined how three psychosocial barriers-anticipated HIV stigma, HIV infectiousness-reduction beliefs, and optimism about available HIV treatments-related to HIV testing history and acceptance of an at-home HIV test among men who have sex with men. We also examined the mediating role of a variable that affects medical screening for other health conditions but has not yet been investigated in HIV contexts: the tendency to avoid psychologically threatening information. Volunteers completed a paper and pencil survey and were offered a free at-home HIV test during the 2015 Atlanta Pride Festival in Atlanta, GA. Anticipated HIV stigma, infectiousness beliefs, and treatment optimism were inconsistently related to HIV testing history and acceptance of an at-home HIV test, but all had direct effects on the desire to avoid HIV information. In a mediation model, each of these psychosocial barriers had indirect effects on both HIV testing outcomes via information avoidance. These findings suggest that information avoidance is an important proximal HIV testing barrier, thus providing a novel target for interventions and information campaigns.

A Systematic Review and Meta-analysis of Antiretroviral Therapy (ART) Adherence Interventions for Women Living with HIV.

A systematic review and meta-analysis was conducted to determine the efficacy of women-focused ART adherence interventions. Included studies (a) reported on a behavioral ART adherence intervention for cis-women living with HIV, (b) measured ART adherence as an outcome, and (c) employed a randomized controlled trial design. Thirteen studies were included in the meta-analysis. Overall, interventions significantly improved ART adherence compared to control conditions (random-effects d = 0.82, 95% CI [0.18, 1.45], p = 0.01), however, this was largely driven by two studies that had effect sizes greater than 3 standard errors above the mean effect size. Key moderators were location, recruitment method, group-based intervention, and alteration of the healthcare system. Innovative behavioral interventions that focus on young women and adolescents, target the critical periods of pregnancy and postpartum and test the integration of multiple levels of intervention to create lasting effects on ART adherence are needed.

Transgender women and HIV-related health disparities: falling off the HIV treatment cascade.

Background Transgender women living with HIV infection experience poorer health outcomes across the HIV continuum of care. While disparities are well established, their underlying mechanisms are not well understood. This study examined the HIV continuum of care (also known as the HIV treatment cascade), including linkage and engagement in care and health status among transgender women and cisgender women and cisgender men living with HIV. METHOD: Case-control matching was applied to a cohort of 1101 people living with HIV; 70 transgender women living with HIV were matched on years since testing HIV positive with cisgender women and cisgender men. Participants provided measures indicative of the HIV treatment cascade that included linkage and engagement in care, receiving and adhering to antiretroviral therapy (ART), and HIV viral suppression. Common correlates of HIV-related health status: depression symptoms, HIV-related stress, alcohol and drug use, healthcare conspiracy beliefs, medical mistrust, emotional social support and tangible social support, were also assessed. RESULTS: Transgender women were significantly less likely to receive ART, were less adherent to ART and had poorer HIV viral suppression than cisgender persons. Multivariable models demonstrated that health disparities were predicted by transgender women having poorer tangible social support over and above the other correlates of health outcomes. CONCLUSION: Tangible support is amenable by interventions such as building and strengthening supportive networks and paraprofessional services. Socially supportive interventions should be considered critical in efforts to decrease HIV health disparities among transgender women.

The differences between medical trust and mistrust and their respective influences on medication beliefs and ART adherence among African-Americans living with HIV.

OBJECTIVE: The purpose of this study was to examine the relationships between medical mistrust and trust and to determine if these measures differentially predict antiretroviral therapy (ART) medication adherence for African-American adults living with HIV. DESIGN: A total of 458 HIV positive African-Americans completed a cross-sectional survey. MAIN OUTCOME MEASURES: Self-reported ART adherence was collected using the visual-analog scale. The Beliefs About Medicines Questionnaire was used to assess medication necessity and concern beliefs. RESULTS: All measures of medical mistrust and trust were significantly negatively correlated, ranging from r = -.339 to -.504. Race-based medical mistrust significantly predicted medication necessity and concern beliefs, whereas general medical mistrust only significantly predicted medication concerns. Both measures of trust significantly predicted medication necessity beliefs and medication concerns. Higher levels of race-based medical mistrust predicted lower medication adherence, whereas, neither trust in own physician nor trust in health care provider significantly predicted medication adherence. However, trust in own physician significantly predicted medication necessity beliefs, which predicted medication adherence. CONCLUSION: Trust and mistrust are not simply opposites of one another. These findings provide evidence for the complexity of understanding the relationship between health care trust, mistrust and patient-related health beliefs and behaviours.

Diminishing Perceived Threat of AIDS and Increasing Sexual Risks of HIV Among Men Who Have Sex with Men, 1997-2015.

Community-wide awareness that antiretroviral therapies (ART) provides protection against HIV has the potential to increase perceived safety and thereby increase condomless anal sex among men who have sex with men (MSM). Furthermore, reductions in condom use can increase exposure to sexually transmitted infections, which in turn can reduce the protective effects of ART on HIV transmission. The current study extends previous community-based behavioral surveillance research on beliefs regarding use of ART for HIV prevention and sexual practices among MSM. Anonymous cross-sectional community surveys were collected from 1831 men at the same gay pride event in Atlanta, GA four times over nearly two decades; 1997, 2005-2006 (the 2006 survey over-sampled African-Americans to diversify the study), and 2015. Results indicate clear and consistent trends of increasing beliefs that HIV treatments reduce HIV transmission risks, reflecting the dissemination of HIV prevention research findings. Changes in treatment beliefs coincide with increased rates of condomless anal intercourse. Increased beliefs that treatments prevent HIV and increased condomless anal sex were observed for both HIV positive men and men who had not tested HIV positive. Results illustrate the emergence of an era where ART is the focus of HIV prevention and community-held beliefs and behaviors regarding definitions of risk create a new and potentially problematic environment for HIV transmission.

Stigma and Conspiracy Beliefs Related to Pre-exposure Prophylaxis (PrEP) and Interest in Using PrEP Among Black and White Men and Transgender Women Who Have Sex with Men.

The HIV/AIDS epidemic in the US continues to persist, in particular, among race, sexual orientation, and gender minority populations. Pre-exposure prophylaxis (PrEP), or using antiretroviral medications for HIV prevention, is an effective option, but uptake of PrEP has been slow. Sociocultural barriers to using PrEP have been largely underemphasized, yet have the potential to stall uptake and, therefore, warrant further understanding. In order to assess the relationships between potential barriers to PrEP (i.e., PrEP stigma and conspiracy beliefs), and interest in PrEP, Black men and transgender women who have sex with men (BMTW, N = 85) and White MTW (WMTW, N = 179) were surveyed at a gay pride event in 2015 in a large southeastern US city. Bivariate and multivariate logistic regression analyses were completed to examine factors associated with PrEP interest. Among the full sample, moderate levels of PrEP awareness (63%) and low levels of use (9%) were observed. Believing that PrEP is for people who are promiscuous (stigma belief) was strongly associated with lack of interest in using PrEP, and individuals who endorsed this belief were more likely to report sexual risk taking behavior. Conspiracy beliefs related to PrEP were reported among a large minority of the sample (42%) and were more frequently reported among BMTW than WMTW. Given the strong emphasis on the use of biomedical strategies for HIV prevention, addressing sociocultural barriers to PrEP access is urgently needed and failure to do so will weaken the potential benefits of biomedical prevention.

Pooled Open Blocks Shorten Wait Times for Nonelective Surgical Cases.

OBJECTIVE: Assess the impact of the implementation of a data-driven scheduling strategy that aimed to improve the access to care of nonelective surgical patients at Massachusetts General Hospital (MGH). BACKGROUND: Between July 2009 and June 2010, MGH experienced increasing throughput challenges in its perioperative environment: approximately 30% of the nonelective patients were waiting more than the prescribed amount of time to get to surgery, hampering access to care and aggravating the lack of inpatient beds. METHODS: This work describes the design and implementation of an "open block" strategy: operating room (OR) blocks were reserved for nonelective patients during regular working hours (prime time) and their management centralized. Discrete event simulation showed that 5 rooms would decrease the percentage of delayed patients from 30% to 2%, assuming that OR availability was the only reason for preoperative delay. RESULTS: Implementation began in January 2012. We compare metrics for June through December of 2012 against the same months of 2011. The average preoperative wait time of all nonelective surgical patients decreased by 25.5% (P < 0.001), even with a volume increase of 9%. The number of bed-days occupied by nonurgent patients before surgery declined by 13.3% whereas the volume increased by 4.5%. CONCLUSIONS: The large-scale application of an open-block strategy significantly improved the flow of nonelective patients at MGH when OR availability was a major reason for delay. Rigorous metrics were developed to evaluate its performance. Strong managerial leadership was crucial to enact the new practices and turn them into organizational change.
