Disruptions to HIV services due to the COVID pandemic in the USA: a state-level stakeholder perspective.

BACKGROUND: The United States envisions a 90% reduction in HIV infections by 2030. However, the COVID-19 pandemic disrupted the HIV continuum and disproportionately affected access to social and health services for people at the highest vulnerability. This study shows how stakeholders in the State of Michigan handled disruptions and their key recommendations. As a case study, this study adds to the literature about preparedness for future pandemics. METHODS: We interviewed 33 statewide Michigan HIV/AIDS Council members-practitioners, researchers, and community representatives, guiding service planning, improvement, and resource allocations, measuring group cohesiveness using a tested scale. We measured group cohesiveness as a proxy for how individual opinions reflected those of the Council as a group. We used qualitative questions to assess: (1) how the COVID-19 pandemic disrupted HIV prevention; (2) how disruptions were handled; and (3) recommendation to help address disruptions now and in the future. Using thematic analysis, we coded the interviews. RESULTS: We found a high degree of cohesiveness. Participants agreed that the pandemic disrupted HIV prevention services (e.g., HIV testing, PrEP education, referrals to primary care, etcetera) offered by community organizations, hospital clinics, and health departments across the state. In response, they developed online and curbside services to maintain HIV services, abate social isolation, and address structural issues like lack of food and public transportation. We organized results in four categories: (1) HIV service disruptions (e.g., "Housing for women and children who are fleeing a legal situation"); (2) Responses to disruptions (e.g., "Some of them, we would say, hey, weather permitting, we'll come out to your car"); (3) Minoritized groups disproportionately affected (e.g., "Especially in my community, to get people if there's ever a vaccine, Black people are going to be the last people to take it"); and (4) Recommendations (below). CONCLUSIONS: The pandemic unsettled and further exacerbated every aspect of HIV service provision. The main recommendation was to overhaul communication systems between government and organizations offering HIV services to mitigate disruptions and improve the chances of achieving a 90% reduction.

Expanding Knowledge About Music and Well-Being in Carceral Settings: A Methodological Review.

This methodological review includes literature (1987-2022) concerning the role and influence of musical practices-including music therapy and participatory music interventions-on well-being in carceral settings such as jails, prisons, and immigration detention centers. We provide a thorough description of key methodological procedures used in 55 studies: (1) Key Elements of Research Questions; (2) Types of Musical Practices; (3) Musical Genres; (4) Methodologies and Designs; (5) Locations; (6) Theoretical Frameworks; and (7) Samples. Our review indicates that there is difficulty in conducting research in prisons due to limitations imposed on researchers, a paucity of randomized-control trials, and limited generalizability of results due to the heterogeneity of methodological approaches. We suggest that the literature base would benefit from increased attention to issues related to sampling procedures, research questions related to race and gender identity, as well as the delineation between the types of musical practices utilized by music interventions.

Music and well-being in carceral settings: a scoping review.

Well-being is defined as the multi-dimensional experience of positive emotions, as well as life satisfaction, autonomy, and purpose. This scoping review examines the impact of musical practices on the well-being of incarcerated individuals and uniquely contributes to the literature by focusing on the relationship between music and power in carceral settings and by expounding on the ways in which musical practices both facilitate and inhibit experiences of well-being. Our review contributes to this body of literature by proposing three distinct ways musical practices may affect well-being: (1) Musical Practices and Psychological Outcomes, (2) Musical Practices and Identity Formation and (3) Musical Practices and Power.

Injectable Long-Acting Cabotegravir-Rilpivirine Therapy for People Living With HIV/AIDS: Addressing Implementation Barriers From the Start.

ABSTRACT: Injectable cabotegravir and rilpivirine (CAB/RPV), administered bimonthly by a medical provider, is convenient and improves privacy and medication management. One year after approval, myriad implementation barriers threaten the access and sustainability of this life-saving innovation: (1) eligibility issues (viral suppression, drug resistance, and failed oral regimens); (2) injection requires medical provider and transportation to facility; (3) strict medication adherence; (4) life challenges-mental health, homelessness, joblessness; and (5) lack of insurance and high cost. Universal implementation of CAB/RPV calls for social, human, and health organizations to partner and provide HIV continuum of care and prevention services to facilitate CAB/RPV access and maintenance and for transparent health insurance billing practices to abate uncertainty concerning CAB/RPV's classification as a pharmaceutical or medical benefit and related cost implications.

Enhancing behavioral intervention science: using community-based participatory research principles with the multiphase optimization strategy.

Innovative methodological frameworks are needed in intervention science to increase efficiency, potency, and community adoption of behavioral health interventions, as it currently takes 17 years and millions of dollars to test and disseminate interventions. The multiphase optimization strategy (MOST) for developing behavioral interventions was designed to optimize efficiency, efficacy, and sustainability, while community-based participatory research (CBPR) engages community members in all research steps. Classical approaches for developing behavioral interventions include testing against control interventions in randomized controlled trials. MOST adds an optimization phase to assess performance of individual intervention components and their interactions on outcomes. This information is used to engineer interventions that meet specific optimization criteria focused on effectiveness, cost, or time. Combining CBPR and MOST facilitates development of behavioral interventions that effectively address complex health challenges, are acceptable to communities, and sustainable by maximizing resources, building community capacity and acceptance. Herein, we present a case study to illustrate the value of combining MOST and CBPR to optimize a multilevel intervention for reducing substance misuse among formerly incarcerated men, for under $250 per person. This integration merged experiential and cutting-edge scientific knowledge and methods, built community capacity, and promoted the development of efficient interventions. Integrating CBPR and MOST principles yielded a framework of intervention development/testing that is more efficient, faster, cheaper, and rigorous than traditional stage models. Combining MOST and CBPR addressed significant intervention science gaps and speeds up testing and implementation of interventions.

Community engagement in dissemination and implementation models: A narrative review.

Background: Responding to the growing demand for scientific understanding of adoption and uptake of evidence-based interventions (EBIs), numerous dissemination and implementation ("D&I") models have been proposed in the extant literature. This review aimed to identify community-specific constructs with the potential to help researchers engage community partners in D&I studies or deploy EBIs. Methods: We identified 74 D&I models targeting community-level changes. We built on Tabak et al.'s narrative review that identified 51 D&I models published up to 2012 and identified 23 D&I models published between 2012 and 2020 from the Health Research & Practice website (16 models) and PubMed database (7 models). Three coders independently examined all 74 models looking for community-specific engagement constructs. Results: We identified five community engagement constructs: (1) Communication, (2) Partnership Exchange, (3) Community Capacity Building, (4) Leadership, and (5) Collaboration. Of the 74 models, 20% reflected all five constructs; 32%, four; 22%, three; 20%, two; and 5%, only one. Few models with strong community content have been introduced since 2009. Conclusion: This article bridges the community-engaged and D&I research literature by identifying community engagement constructs reflected in existing D&I models, targeting community-level changes. Implications for future research and practice are discussed.

Developing a Scale to Measure Interprofessional Collaboration in HIV Prevention and Care: Implications for Research on Patient Access and Retention in the HIV Continuum of Care.

To adapt and validate a scale for measuring interprofessional collaboration in HIV prevention and care (IPC-HIV), primary survey data were collected (2012-2017) from 577 HIV service providers in 60 organizations in New York, New Jersey, and Michigan. Cross-sectional training data were used to develop the IPC-HIV scale. The model was validated by fitting the five-factor confirmatory factor-analysis model to a 30-item set. The scale measures five domains with reliable alpha coefficients: Interdependence, Professional Activities, Flexibility, Collective Ownership, and Reflection on Process. Correlations between subscales were significant (p < .05). The strongest correlation was between Reflection on Process and Collective Ownership subscale scores. Mean scores ranged lfrom 4.070 to 4.880, with the highest score for Flexibility across all locations. IPC-HIV is valid and reliable among HIV-prevention and care workers, and is recommended for examining the effect of IPC on patient access to HIV testing and primary care.

Incidence of Infectious Adverse Events in Patients With Rheumatoid Arthritis and Spondyloarthritis on Biologic Drugs-Data From the Brazilian Registry for Biologics Monitoring.

BACKGROUND: The safety profile of biologic drugs might present substantial regional differences. Since 2009, the Brazilian Society of Rheumatology has maintained BIOBADABRASIL (Brazilian Registry for Biologic Drugs), a registry for monitoring of biologic therapies in rheumatic diseases. OBJECTIVES: The aim of this study was to verify the incidence rate (IR) of serious infections in rheumatoid arthritis (RA) and spondyloarthritis (SpA) patients on biologic drugs. METHODS: BIOBADABRASIL prospectively included patients with rheumatic diseases who started the first biologic drug or a synthetic disease-modifying antirheumatic drug as a parallel control group. This study focuses on serious infectious adverse events (SIAEs) in RA and SpA patients on biologic drugs compared with controls, from January 2009 to June 2015. Time of exposure was set from initiation of the drug to the date of last administration or censorship. Serious infectious adverse events IR was calculated per 1000 patient/years with 95% confidence interval (CI). RESULTS: A total of 1698 patients (RA, 1121; SpA, 577) were included, 7119 patient/years. Serious infectious adverse events were more common among patients on tumor necrosis factor inhibitors (TNFi's) than controls (adjusted IR ratio, 2.96 [95% CI, 2.01-4.36]; p < 0.001). Subsequent TNFi was associated with a higher SIAEs incidence when compared with first TNFI (adjusted IR ratio, 1.55 [95% CI, 1.15-2.08]; p = 0.004). Serious infectious adverse events were associated with age and corticosteroids intake. Serious infectious adverse events were more frequent in the respiratory tract in all subgroups. CONCLUSIONS: In BIOBADABRASIL, biologic drugs, especially the subsequent TNFi, were associated with a higher risk of serious infections compared with synthetic DMARDs. Corticosteroid intake and age represented risk factors for SIAEs. Constant monitoring is required to follow the safety profile of drugs in the clinical setting of rheumatic conditions in Brazil.

Interprofessional Collaboration Improves the Odds of Educating Patients About PrEP over Time.

BACKGROUND: Low levels of pre-exposure prophylaxis (PrEP) uptake continue among the most vulnerable (e.g., men who have sex with men) for HIV exposure in the USA. Providers of social and public health services ("psychosocial providers") can help improve this situation by educating patients about PrEP before linking them to primary care providers (PCPs). OBJECTIVE: To identify predictors of psychosocial providers offering PrEP education to patients vulnerable to HIV infection by determining the frequency with which psychosocial providers offer PrEP education to patients. DESIGN: Longitudinal overview of PrEP implementation in New York City. PARTICIPANTS: Psychosocial providers of HIV prevention and adjunct treatment services, such as medication adherence counseling in 34 community settings. MAIN MEASURES: Longitudinal survey data collected in 2014-2016 (baseline) and 2015-2017 (1-year follow-up) from a 5-year longitudinal repeated measures study. Logistic regression modeling tested associations between baseline psychosocial provider-level and organization-level characteristics and frequency of PrEP education at baseline and 1-year follow-up. KEY RESULTS: Out of 245 participants, the number of psychosocial providers offering PrEP education at least once in the past 6 months increased significantly from baseline (n = 127, 51.8%) to 1-year follow-up (n = 161, 65.7%). Participants with higher odds of offering PrEP education at baseline and at one1-year follow-up were more likely to have reported high levels of interprofessional collaboration (IPC) and were also more likely to have received formal HIV prevention training. CONCLUSIONS: Both IPC and HIV training are predictive of PrEP education, and this association was maintained over time. We recommend expanding educational outreach efforts to psychosocial providers to further improve PrEP education and also training in interprofessional collaboration. This is an important first step toward linking patients to PCPs who prescribe PrEP and may help improve PrEP uptake.

Using community-engaged methods to adapt virtual reality job-interview training for transition-age youth on the autism spectrum.

BACKGROUND: Virtual Reality Job-Interview Training (VR-JIT) is an efficacious Internet-based intervention for adults with severe mental illness (SMI). Evaluations of VR-JIT have shown improved interview skill and access to employment in several cohorts of adults with SMI and with autism spectrum disorders (ASD). VR-JIT trains participants how to fill out job applications and handle job interviews through e-learning content and applied practice. Trainees receive feedback through in-the-moment nonverbal cues, critiques, and recommendations for improving performance. Our study sought to adapt VR-JIT for transition-age youth with ASD (TAY-ASD). METHODS: We recruited TAY-ASD and adult stakeholders from public and charter schools, transition programs, and community service providers. Participants provided feedback on VR-JIT to enhance its applicability to TAY-ASD. We used community-engaged methods to process and analyze data from TAY-ASD and stakeholders, presented their quantitative and qualitative responses to community and scientific advisory boards for review and recommendations, and adapted the intervention design and content. RESULTS: Our adaptations included adding diversity (gender; race/ethnicity) to the virtual hiring manager; shortening the interview by reducing response options; increasing social storytelling to enhance engagement with VR-JIT core components; adding employment opportunities more relevant to younger workers; reducing the reading level; and making the e-learning content more accessible by adding bullet points, voiceover, and imagery/video; and adding new learning goals. CONCLUSIONS: This study presents a rigorous and innovative community-engaged methodology for adapting VR-JIT to meet the needs of TAY-ASD. We review our engagement with TAY-ASD and stakeholders, and discuss the standardized coding scheme we used to adapt VR-JIT and the usefulness and limitations of employing this methodology in adapting other behavioral interventions.

Interprofessional collaboration improves linkages to primary care: a longitudinal analysis.

The first steps of the HIV care continuum include patients finding access to HIV testing and primary care. Psychosocial providers ("providers"), such as social workers, health educators, and outreach workers comprise a workforce tasked with linking patients to HIV testing and primary care. This study examines longitudinal associations between provider- and organization-level factors and linkage to HIV testing and primary care. The sample included 245 providers in 36 agencies in New York City. We used longitudinal data (baseline and 12- and 24-months follow-ups) and multilevel ordinal logistic regression to examine associations between factors distributed in three theoretical socioecological domains: individual (demographic and HIV training characteristics); relationship (interprofessional collaboration); and agency (size and capacity), and frequency of HIV testing and primary care linkages. Approximately 30% of providers linked 20 or more patients to HIV testing or HIV primary care in the previous six months. Providers' higher endorsement of interprofessional collaboration at 12 months, formal HIV training, younger age, and Latinx ethnicity had higher odds of making more linkages to HIV testing and HIV primary care at 24 months. Training providers in interprofessional collaboration principles and practice and basic HIV knowledge may improve the frequency of linkages to HIV care continuum services.

Is Insurance a Barrier to HIV Preexposure Prophylaxis? Clarifying the Issue.

Clinical trials have demonstrated that preexposure prophylaxis (PrEP) protects against HIV infection; yet, even with its approval by the Food and Drug Administration (FDA) in 2012, less than 10% of eligible users in the United States are currently taking PrEP.While there are multiple factors that influence PrEP uptake and pose barriers to PrEP implementation, here we focus on PrEP's cost in the United States, which, at the current list price of $2000 per month and with high levels of cost sharing, can leave insured users with more than $1000 in out-of-pocket costs every year. We discuss how patient deductibles, monthly premiums, copayments, and coinsurance vary widely and may increase the financial burden. Although drug payment-assistance programs have made PrEP more affordable to uninsured and underinsured users, lack of insurance is a barrier to PrEP accessibility. The FDA approved a generic version in 2017; however, that version has not been distributed to US consumers and may not be more affordable.As other countries begin implementing PrEP programs, the extent of PrEP's availability as a tool in the global fight against HIV remains to be seen.

Expanding Knowledge About Implementation of Pre-exposure Prophylaxis (PrEP): A Methodological Review.

Methodological limitations in PrEP implementation studies may explain why PrEP implementation is lagging. This methodological review provides a description and critique of the methods used to identify barriers to PrEP implementation in the United States (2007-18). For each selected article, we provide: (1) research questions; (2) measures; (3) design; (4) sample (size and type); and (5) theoretical orientation. Among 79 articles which identified knowledge, attitudes, and behavioral and social/structural barriers to PrEP implementation, 51 (65%) were quantitative; 25 (32%) qualitative; and 3 (4%) were mixed-methods; overall, just one-half described a conceptual approach. About two-thirds of articles were conducted with patients and one-third with healthcare providers. Our review reveals a paucity of longitudinal, mixed-methods, and ethnographic/observational research and guiding theoretical frameworks; thus, the applicability of results are limited. We recommend that interventions aimed at PrEP implementation address barriers situated at multiple ecological domains, and thus improve PrEP access, uptake, and adherence.

Predicting Retention in HIV Primary Care: Is There a Missed Visits Continuum Based on Patient Characteristics?

Missing 3 + scheduled HIV primary care visits over a 1-year period increases mortality risk for people living with HIV (PLWH). We used electronic health data from PLWH (≥ 18 years old) at a southeastern US HIV clinic in 2016 to examine differences across patient-level characteristics and number of missed visits (1-2 vs. 0, 3 + vs. 0, 3 + vs. 1-2). In multivariable multinomial logistic regression analyses, poverty, lack of Ryan White HIV/AIDS Program support services, being uninsured, not having a high school degree, and being younger were significantly associated with 1-2 or 3 + missed visits (vs. 0 missed). Only poverty remained predictive of missing 3 + versus 1-2 visits (RR = 2.70, 95% CI 1.49-4.88). Patients at risk for missing 3 + visits present similar characteristics to patients who miss 1-2 visits. Interventions aimed at poverty reduction and increased access to education, health insurance, and support services may improve retention and, therefore, decrease mortality risk.

Nurturing Practitioner-Researcher Partnerships to Improve Adoption and Delivery of Research-Based Social and Public Health Services Worldwide.

Research-based practices-psychosocial, behavioral, and public health interventions-have been demonstrated to be effective and often cost-saving treatments, but they can take up to two decades to reach practitioners within the health and human services workforce worldwide. Practitioners often rely on anecdotal evidence and their "practice wisdom" rather than on research, and may thus unintentionally provide less effective or ineffective services. Worldwide, community engagement in research is recommended, particularly in low-resource contexts. However, practitioner involvement has not been adequately explored in its own right as an innovative community-engaged practice that requires a tailored approach. The involvement of practitioners in research has been shown to improve their use of research-based interventions, and thus the quality of care and client outcomes. Nevertheless, the literature is lacking specificity about when and how (that is, using which tasks and procedures) to nurture and develop practitioner⁻researcher partnerships. This paper offers theoretical and empirical evidence on practitioner⁻researcher partnerships as an innovation with potential to enhance each phase of the research cycle and improve services, using data from the United States, Brazil, and Spain. Recommendations for partnership development and sustainability are offered, and a case is made for involving practitioners in research in order to advance social justice by amplifying the local relevance of research, increasing the likelihood of dissemination to community settings, and securing the sustainability of research-based interventions in practice settings.

No Easy Answers: Avoiding Potential Pitfalls of De-implementation.

In 2012, the Centers for Disease Control and Prevention (CDC) began to de-emphasize and de-implement multiple evidence-based HIV prevention practices that had been around for 20 years, thus changing the scope of implementation across the globe. The authors provide evidence how existing interventions (e.g., CDC HIV interventions) may influence implementation of interventions that came after the program was discontinued. De-implementation is an ecological event that influences, and is influenced by, many parts of a system, for instance, implementation of one type of intervention may influence the implementation of other interventions (biomedical and/or behavioral) after a long-running program is discontinued. Researchers and policy makers ought to consider how de-implementation of behavioral interventions is influenced by biomedical interventions mass-produced by companies with lobbying power. The scientific study of de-implementation will be inadequate without consideration of the political climate that surrounds de-implementation of certain types of interventions and the promotion of more-profitable ones.

Recruiting and retaining service agencies and public health providers in longitudinal studies: Implications for community-engaged implementation research.

This article addresses a lack of attention in the implementation science literature regarding how to overcome recruitment and retention challenges in longitudinal studies involving large samples of service agencies and health service providers ("providers"). Herein, we provide a case-illustration of procedures that improved recruitment and retention in a longitudinal, mixed-method study-Project Interprofessional Collaboration Implementation-funded by the US National Institute of Mental Health. Project Interprofessional Collaboration Implementation included counselors, program workers, educators, and supervisors. We present a research-engagement model to overcome barriers that included developing a low-burden study, social gatherings to engage stakeholders, protocols to recruit agencies and providers, comprehensive record-keeping, research procedures as incentives to participation, a plan to retain hard-to-reach participants, and strategies for modifying incentives over time. Using our model, we retained 36 agencies over the life of the project. Between baseline (N = 379) and 12-month follow-up (N = 285), we retained 75% of the sample and between the 12- (N = 285) and 24-month follow-ups (N = 256), we retained 90%. For qualitative interviews (between baseline and 12-month follow-up and between 12- and 24-month follow-ups), we retained 100% of the sample (N = 20). We provide a summary of frequency of contacts required to initiate data collection and time required for data collection. The model responded to environmental changes in policy and priorities that would not have been achievable without the expertise of community partners. To recruit and retain large samples longitudinally, researchers must strategically engage community partners. The strategies imbedded in our model can be performed with moderate levels of effort and human resources. Creating opportunities for research partners to participate in all phases of the research cycle is recommended, which can help build research capacity for future research.

Improving PrEP Implementation Through Multilevel Interventions: A Synthesis of the Literature.

There are many challenges to accessing PrEP and thus low uptake in the United States. This review (2007-2017) of PrEP implementation identified barriers to PrEP and interventions to match those barriers. The final set of articles (n = 47) included content on cognitive aspects of HIV service providers and individuals at risk for infection, reviews, and case studies. Cognitive barriers and interventions regarding patients and providers included knowledge, attitudes, and beliefs about PrEP. The "purview paradox" was identified as a key barrier-HIV specialists often do not see HIV-negative patients, while primary care physicians, who often see uninfected patients, are not trained to provide PrEP. Healthcare systems barriers included lack of communication about, funding for, and access to PrEP. The intersection between PrEP-stigma, HIV-stigma, transphobia, homophobia, and disparities across gender, racial, and ethnic groups were identified; but few interventions addressed these barriers. We recommend multilevel interventions targeting barriers at multiple socioecological domains.

Optimizing a community-engaged multi-level group intervention to reduce substance use: an application of the multiphase optimization strategy.

BACKGROUND: Rates of alcohol and illicit drug use (AIDU) are consistently similar across racial groups (Windsor and Negi, J Addict Dis 28:258-68, 2009; Keyes et al. Soc Sci Med 124:132-41, 2015). Yet AIDU has significantly higher consequences for residents in distressed communities with concentrations of African Americans (DCAA - i.e., localities with high rates of poverty and crime) who also have considerably less access to effective treatment of substance use disorders (SUD). This project is optimizing Community Wise, an innovative multi-level behavioral-health intervention created in partnership with service providers and residents of distressed communities with histories of SUD and incarceration, to reduce health inequalities related to AIDU. METHODS: Grounded in critical consciousness theory, community-based participatory research principles (CBPR), and the multiphase optimization strategy (MOST), this study employs a 2 × 2 × 2 × 2 factorial design to engineer the most efficient, effective, and scalable version of Community Wise that can be delivered for US$250 per person or less. This study is fully powered to detect change in AIDU in a sample of 528 men with a histories of SUD and incarceration, residing in Newark, NJ in the United States. A community collaborative board oversees recruitment using a variety of strategies including indigenous field worker sampling, facility-based sampling, community advertisement through fliers, and street outreach. Participants are randomly assigned to one of 16 conditions that include a combination of the following candidate intervention components: peer or licensed facilitator, group dialogue, personal goal development, and community organizing. All participants receive a core critical-thinking component. Data are collected at baseline plus five post-baseline monthly follow ups. Once the optimized Community Wise intervention is identified, it will be evaluated against an existing standard of care in a future randomized clinical trial. DISCUSSION: This paper describes the protocol of the first ever study using CBPR and MOST to optimize a substance use intervention targeting a marginalized population. Data from this study will culminate in an optimized Community Wise manual; enhanced methodological strategies to develop multi-component scalable interventions using MOST and CBPR; and a better understanding of the application of critical consciousness theory to the field of health inequalities related to AIDU.
