Implementing a Pre-Exposure Prophylaxis Intervention for Safer Conception among HIV Serodiscordant Couples: Recommendations for Health Care Providers

Couples in HIV serodiscordant relationships frequently desire children. Although partners who are virally suppressed pose almost no risk of transmitting HIV to their partners, partners who are inconsistently on therapy may transmit HIV to their partners when attempting to conceive. Pre-exposure prophylaxis (PrEP) is an available safer conception strategy for these couples but is not consistently offered. We sought to better understand barriers to PrEP implementation for couples seeking conception and patient perceptions on what providers could do to encourage use. We conducted in-depth, qualitative interviews with 11 participants representing six couples taking PrEP for safer conception in a safety-net hospital in New England. Semi-structured qualitative interviews assessed the following: Relationship nature and contextual factors; attitudes and perceptions regarding PrEP for safer conception; experience within health care systems related to HIV and PrEP; and facilitators, barriers, and other experiences using PrEP for safer conception. Four key themes have important implications for implementation of PrEP for safer conception: Knowledge and understanding gaps regarding HIV and PrEP among both members of the couple, role of insurance and financing in decision-making, learning to manage and adhere to a treatment plan, and the need for providers to enhance knowledge and offer further support. Addressing barriers to safer conception strategies at multiple levels is needed to prevent HIV transmission within serodiscordant couples who desire children. Providers can play an important role in lowering these barriers through the use of multiple strategies

Standardizing an approach to the evaluation of implementation science proposals

Abstract Background The fields of implementation and improvement sciences have experienced rapid growth in recent years. However, research that seeks to inform health care change may have difficulty translating core components of implementation and improvement sciences within the traditional paradigms used to evaluate efficacy and effectiveness research. A review of implementation and improvement sciences grant proposals within an academic medical center using a traditional National Institutes of Health framework highlighted the need for tools that could assist investigators and reviewers in describing and evaluating proposed implementation and improvement sciences research. Methods We operationalized existing recommendations for writing implementation science proposals as the ImplemeNtation and Improvement Science Proposals Evaluation CriTeria (INSPECT) scoring system. The resulting system was applied to pilot grants submitted to a call for implementation and improvement science proposals at an academic medical center. We evaluated the reliability of the INSPECT system using Krippendorff’s alpha coefficients and explored the utility of the INSPECT system to characterize common deficiencies in implementation research proposals. Results We scored 30 research proposals using the INSPECT system. Proposals received a median cumulative score of 7 out of a possible score of 30. Across individual elements of INSPECT, proposals scored highest for criteria rating evidence of a care or quality gap. Proposals generally performed poorly on all other criteria. Most proposals received scores of 0 for criteria identifying an evidence-based practice or treatment (50%), conceptual model and theoretical justification (70%), setting’s readiness to adopt new services/treatment/programs (54%), implementation strategy/process (67%), and measurement and analysis (70%). Inter-coder reliability testing showed excellent reliability (Krippendorff’s alpha coefficient 0.88) for the application of the scoring system overall and demonstrated reliability scores ranging from 0.77 to 0.99 for individual elements. Conclusions The INSPECT scoring system presents a new scoring criteria with a high degree of inter-rater reliability and utility for evaluating the quality of implementation and improvement sciences grant proposals

Systematic review of HIV treatment adherence research among people who inject drugs in the United States and Canada: evidence to inform pre-exposure prophylaxis (PrEP) adherence interventions

Abstract Background People who inject drugs (PWID) are at increased risk for HIV acquisition and could benefit from antiretroviral pre-exposure prophylaxis (PrEP). However, PrEP has been underutilized in this population, and PrEP adherence intervention needs are understudied. Methods To inform PrEP intervention development, we reviewed evidence on antiretroviral therapy (ART) adherence among HIV-infected PWID. Guided by a behavioral model of healthcare utilization and using the PICOS framework, we conducted a systematic review in four electronic databases to identify original research studies of ART adherence in HIV-infected PWID in the United States and Canada between Jan 1, 2006–Dec 31, 2016. We synthesized and interpreted findings related to developing recommendations for PrEP adherence interventions for PWID. Results After excluding 618 duplicates and screening 1049 unique records, we retained 20 studies of PWID (mean n = 465) with adherence-related outcomes (via pharmacy records: n = 9; self-report: n = 8; biological markers: n = 5; electronic monitoring: n = 2). Predisposing factors (patient-level barriers to adherence) included younger age, female sex, and structural vulnerability (e.g., incarceration, homelessness). Enabling resources (i.e., facilitators) that could be leveraged or promoted by interventions included self-efficacy, substance use treatment, and high-quality patient-provider relationships. Competing needs that require specific intervention strategies or adaptations included markers of poor physical health, mental health comorbidities (e.g., depression), and engagement in transactional sex. Conclusions HIV treatment adherence research carries important lessons for efforts to optimize PrEP adherence among PWID. Despite limitations, this systematic review suggests that strategies are needed to engage highly vulnerable and marginalized sub-groups of this underserved population (e.g., younger PWID, women who inject drugs) in PrEP adherence-related research and programming

Evidence-based and guideline-concurrent responses to narratives deferring HCV treatment among people who inject drugs

Abstract Background Hepatitis C virus (HCV) infection is increasingly prevalent among people who inject drugs (PWID) in the context of the current US opioid crisis. Although curative therapy is available and recommended as a public health strategy, few PWID have been treated. We explore PWID narratives that explain why they have not sought HCV treatment or decided against starting it. We then compare these narratives to evidence-based and guideline-concordant information to better enable health, social service, harm reduction providers, PWID, and other stakeholders to dispel misconceptions and improve HCV treatment uptake in this vulnerable population. Methods We recruited HIV-uninfected PWID (n = 33) through community-based organizations (CBOs) to participate in semi-structured, in-depth qualitative interviews on topics related to overall health, access to care, and knowledge and interest in specific HIV prevention methods. Results In interviews, HCV transmission and delaying or forgoing HCV treatment emerged as important themes. We identified three predominant narratives relating to delaying or deferring HCV treatment among PWID: (1) lacking concern about HCV being serious or urgent enough to require treatment, (2) recognizing the importance of treatment but nevertheless deciding to delay treatment, and (3) perceiving that clinicians and insurance companies recommend that patients who currently use or inject drugs should delay treatment. Conclusions Our findings highlight persistent beliefs among PWID that hinder HCV treatment utilization. Given the strong evidence that treatment improves individual health regardless of substance use status while also decreasing HCV transmission in the population, efforts are urgently needed to counter the predominant narratives identified in our study. We provide evidence-based, guideline-adherent information that counters the identified narratives in order to help individuals working with PWID to motivate and facilitate treatment access and uptake. An important strategy to improve HCV treatment initiation among PWID could involve disseminating guideline-concordant counternarratives to PWID and the providers who work with and are trusted by this population

Effect of a multi-component intervention on providers\u27 HPV vaccine communication

: To evaluate the effect of a multi-component intervention including communication training on provider beliefs and recommendation practices around the human papillomavirus (HPV) vaccine using both self-reports and audio-recordings of clinical interactions. : We conducted a mixed method study at five family medicine and pediatric practices. Providers self-reported beliefs and practices about HPV vaccination via surveys and qualitative interviews conducted pre- and post-intervention. We also assessed provider recommendation style using audio-recordings of clinical interactions pre- and post-intervention. Content analysis was used to identify themes in qualitative interviews. Matched pre- and post-intervention surveys were analyzed for changes in provider beliefs and attitudes. Pre- and post-intervention audio recordings of clinical interactions were analyzed for observed differences in recommendation styles. Bivariate analyses of quantitative data used Chi-square and Fisher\u27s exact tests; t-tests were used for continuous variables. : Providers reported in interviews that the intervention led to communication changes by increasing their knowledge, reframing the HPV vaccine as a routine vaccination, and providing tools for engaging with parents. Surveys indicated that the proportion of providers reporting that the HPV vaccine is one of the most important adolescent vaccines increased from 71% pre-intervention to 100% post-intervention ( = .03). Audio-recording analysis demonstrated that use of an indicated (presumptive) recommendation style increased from 62.5% pre-intervention to 79.6% post-intervention ( = .047). : Educating providers about HPV vaccination and giving them tools to facilitate communication with parents can reframe HPV as a routine adolescent vaccination and motivate providers to routinely use effective recommendation styles in practice

“Health Is on the Back Burner:” Multilevel Barriers and Facilitators to Primary Care Among People Who Inject Drugs

BackgroundThe estimated 2.2 million people who inject drugs (PWID) in the USA experience significant gaps in preventive healthcare and a high burden of infectious, psychiatric, and other chronic diseases. Many PWID rely on emergency medical services, which are costly and not designed to deliver preventive services, manage chronic conditions, or address social needs.ObjectiveThe objective of this study was to explore barriers and facilitators to primary care utilization from the perspectives of PWID in New England, a region highly affected by the overdose crisis.DesignParticipants completed semi-structured qualitative interviews exploring substance use and healthcare utilization patterns.ParticipantsWe recruited 78 PWID through community-based organizations (e.g., syringe service programs) in 16 urban and non-urban communities throughout Massachusetts and Rhode Island.ApproachThematic analysis identified barriers and facilitators to primary care utilization at the individual, interpersonal, and systemic levels.Key resultsAmong 78 PWID, 48 described recent primary care experiences; 33 had positive experiences and 15 described negative experiences involving discrimination or mistrust. Individual-level barriers to primary care utilization included perceived lack of need and competing priorities (e.g., avoiding opioid withdrawal, securing shelter beds). Interpersonal-level barriers included stigma and perceived low quality of care for PWID. Systemic-level barriers included difficulty navigating healthcare systems, inadequate transportation, long wait times, and frequent provider turnover. Participants with positive primary care experiences explained how appointment reminders, flexible hours, addiction medicine-trained providers, case management services, and transportation support facilitated primary care utilization and satisfaction.ConclusionsFindings regarding the multilevel barriers and facilitators to accessing primary care among PWID identify potential targets for programmatic interventions to improve primary care utilization in this population. Based on these findings, we make recommendations for improving the engagement of PWID in primary care as a means to advance individual and public health outcomes

Improving HPV Vaccination Rates: A Stepped-Wedge Randomized Trial

OBJECTIVES: To evaluate the effectiveness of a stepped-wedge randomized trial of Development of Systems and Education for Human Papillomavirus Vaccination (DOSE HPV), a multilevel intervention. METHODS: DOSE HPV is a 7-session program that includes interprofessional provider education, communication training, data feedback, and tailored systems change. Five primary care pediatric and/or family medicine practices completed interventions between 2016 and 2018; all chose to initiate vaccination at ages 9 to 10. We compared vaccination rates in the preintervention, intervention, and postintervention periods among 9- to 17-year-olds using random-effects generalized linear regression models appropriate for stepped-wedge design, accounting for calendar time and clustering of patients by providers and clinic. Outcomes included (1) the likelihood that eligible patients would receive vaccination during clinic visits; (2) the likelihood that adolescents would complete the series by age 13; and (3) the cumulative effect on population-level vaccine initiation and completion rates. Postintervention periods ranged from 6 to 18 months. RESULTS: In the intervention and postintervention periods, the adjusted likelihood of vaccination at an eligible visit increased by \u3e10 percentage points for ages 9 to 10 and 11 to 12, and completion of the vaccine series by age 13 increased by 4 percentage points ( \u3c .001 for all comparisons). Population-level vaccine initiation coverage increased from 75% (preintervention) to 84% (intervention) to 90% (postintervention), and completion increased from 60% (preintervention) to 63% (intervention) to 69% (postintervention). CONCLUSIONS: Multilevel interventions that include provider education, data feedback, tailored systems changes, and early initiation of the human papillomavirus vaccine series may improve vaccine series initiation and completion beyond the conclusion of the intervention period
