Distrust in the Health Care System and Adherence to Direct-Acting Antiviral Therapy among People with Hepatitis C Virus Who Inject Drugs

This study is a secondary analysis of a randomized clinical trial (October 2013-April 2017) involving 150 People Who Inject Drugs (PWIDs) with hepatitis C virus (HCV) seen in opioid agonist treatment programs in the Bronx, New York, and investigates the impact of distrust in the healthcare system on adherence to Direct-Acting Antivirals (DAAs) HCV treatment therapy among PWIDs. The distrust was scaled on a 9-item instrument and the adherence to DAA medications was measured using electronic blister packs. This study demonstrated a significant inverse relationship between levels of distrust and medication adherence: 71.8 ± 2.2% (se) vs. 77.9 ± 1.8%, p = 0.024 between participants with higher and lower distrust levels. Despite the absence of significant association of distrust with sociodemographic or substance use characteristics, these findings suggest that building trust within the healthcare system is paramount for improving adherence to DAAs among PWIDs. The results call for a healthcare approach that emphasizes trust-building through patient-centered care, sensitivity training, peer support, and health system reform to effectively address the treatment needs of this marginalized population.

COVID-19 vaccination among young people who use drugs in Vancouver, Canada

OBJECTIVES

SARS-CoV-2 vaccines provide significant protection against severe illness and death from COVID-19, in addition to reducing community transmission. Emerging research has identified factors associated with vaccine uptake among adults who use drugs; however, less is known about youth and young adults who use drugs (YWUD). To address this gap, we sought to characterize factors associated with vaccine uptake and explore vaccine hesitancy among YWUD.

METHODS

Data were derived from the At-Risk Youth Study, a prospective cohort of street-involved YWUD in Vancouver, Canada. Using multivariable logistic regression, we characterized factors associated with SARS-CoV-2 vaccine uptake between June and November 2021. Data on vaccine hesitancy were also collected.

RESULTS

Among 301 participants enrolled in this study (median age: 29 [min and max: 20-40]), 151 (50.2%) self-reported receipt of at least one dose of a SARS-CoV-2 vaccine. In multivariable analysis, vaccine uptake was significantly associated with recent addiction treatment engagement (adjusted odds ratio [AOR] = 2.46, 95% confidence interval [CI]: 1.47-4.14) and receiving prescribed safer supply (e.g., opioids, stimulants) (AOR = 2.33, 95% CI: 1.03-5.62). Those who reported at least weekly crack use were significantly less likely to be vaccinated (AOR = 0.35, 95% CI: 0.12-0.92). The most reported reason for vaccine hesitancy was safety concerns, specifically regarding long-term side effects (27.4%).

CONCLUSION

Vaccine uptake was significantly lower among YWUD than adults who use drugs in Vancouver and the general population in British Columbia, among whom 75% and 93% received at least one dose during the same period. Study findings suggest connecting YWUD to healthcare and novel harm reduction interventions may increase vaccine uptake. Responses to vaccine hesitancy questions revealed complex perspectives of vaccines that were aligned with sources of vaccine hesitancy among the general population. Broader strategies combatting misinformation and promoting evidence-based vaccine information could be tailored to address the unique needs and barriers experienced by YWUD.

"It's just not the same": Exploring PWUD' perceptions of and experiences with drug policy and SCS services change in a Canadian City

BACKGROUND AND AIMS

Shifting political contexts can significantly alter drug policy approaches and available supports for People Who Use Drugs (PWUD). The purpose of this study was to explore how shifts in provincial drug policy approaches, specifically the replacement of a Safe Consumption Site (SCS) with a smaller mobile Overdose Prevention Site (OPS) in Lethbridge, Alberta Canada, impacted PWUD' access to and experiences with harm reduction services.

METHODS

We conducted semi-structured interviews with 50 PWUD in the City of Lethbridge, Canada. Through traditional fieldwork, we recruited participants within, and just outside of, downtown Lethbridge. Using a standardized general prompt guide to begin interviews, participants were asked a variety of questions about their experiences with and perceptions of SCS access and changes to SCS provisions. Interviews were audio recorded, then transcribed, coded, and analyzed.

RESULTS

Participants reported regular and frequent access and overall positive experiences with the SCS, despite also noting certain operational barriers (e.g., long wait times). By contrast, participants reported more limited use of the new OPS compared to the SCS because of three main reasons: (1) concerns about location; (2) smoking room elimination; and (3) lack of social space and activities. Overall, changes to SCS provision produced a range of negative consequences for PWUD in Lethbridge. These relate to perceived increases in drug-related harms (e.g., increased overdoses) as well as negative social impacts (e.g., lack of place to meet other people).

CONCLUSION

Findings from this study provide preliminary indications of the importance of understanding how contextual and locally-specific elements (location, limits on permitted route administration, and social aspects) can work together to facilitate SCS uptake and even overcome traditional SCS barriers. Conversely, the absence of such elements can hinder SCS uptake. Results show that the value of SCS might differ across locations, pointing to the need for further locally-grounded examinations of harm reduction service uptake and experience.

The Community-Based Medication-First program for opioid use disorder: a hybrid implementation study protocol of a rapid access to buprenorphine program in Washington State

BACKGROUND

Opioid use disorder (OUD) is a serious health condition that is effectively treated with buprenorphine. However, only a minority of people with OUD are able to access buprenorphine. Many access points for buprenorphine have high barriers for initiation and retention. Health care and drug treatment systems have not been able to provide services to all-let alone the majority-who need it, and many with OUD report extreme challenges starting and staying on buprenorphine in those care settings. We describe the design and protocol for a study of a rapid access buprenorphine program model in six Washington State communities at existing sites serving people who are unhoused and/or using syringe services programs. This study aimed to test the effectiveness of a Community-Based Medication-First Program model.

METHODS

We are conducting a hybrid effectiveness-implementation study of a rapid access buprenorphine model of care staffed by prescribers, nurse care managers, and care navigators. The Community-Based Medication-First model of care was designed as a 6-month, induction-stabilization-transition model to be delivered between 2019 and 2022. Effectiveness outcomes will be tested by comparing the intervention group with a comparison group derived from state records of people who had OUD. Construction of the comparison group will align characteristics such as geography, demographics, historical rates of arrests, OUD medication, and health care utilization, using restriction and propensity score techniques. Outcomes will include arrests, emergency and inpatient health care utilization, and mortality rates. Descriptive statistics for buprenorphine utilization patterns during the intervention period will be documented with the prescription drug monitoring program.

DISCUSSION

Results of this study will help determine the effectiveness of the intervention. Given the serious population-level and individual-level impacts of OUD, it is essential that services be readily available to all people with OUD, including those who cannot readily access care due to their circumstances, capacity, preferences, and related systems barriers.

Discrimination, trust, and withholding information from providers: Implications for missing data and inequity

Quality care requires collaborative communication, information exchange, and decision-making between patients and providers. Complete and accurate data about patients and from patients are especially important as high volumes of data are used to build clinical decision support tools and inform precision medicine initiatives. However, systematically missing data can bias these tools and threaten their effectiveness. Data completeness relies in many ways on patients being comfortable disclosing information to their providers without prohibitive concerns about security or privacy. Patients are likely to withhold information in the context of low trust relationships with providers, but it is unknown how experiences of discrimination in the healthcare system also relate to non-disclosure. In this study, we assess the relationship between withholding information from providers, experiences of discrimination, and multiple types of patient trust. Using a nationally representative sample of US adults (n = 2,029), weighted logistic regression modeling indicated a statistically significant relationship between experiences of discrimination and withholding information from providers (OR 3.7; CI [2.6-5.2], p < .001). Low trust in provider disclosure of conflicts of interest and low trust in providers' responsible use of health information were also positively associated with non-disclosure. We further analyzed the relationship between non-disclosure and the five most common types of discrimination (e.g., discrimination based on race, education/income, weight, gender, and age). We observed that all five types were statistically significantly associated with non-disclosure (p < .05). These results suggest that experiences of discrimination and specific types of low trust have a meaningful association with a patient's willingness to share information with their provider, with important implications for the quality of data available for medical decision-making and care. Because incomplete information can contribute to lower quality care, especially in the context of data-driven decision-making, patients experiencing discrimination may be further disadvantaged and harmed by systematic data missingness in their records.

Applicability of a national strategy for patient-oriented research to people who use(d) substances: a Canadian experience

BACKGROUND

Europe and North America are in the grips of a devastating overdose crisis. People who use substances often feel unsafe to access healthcare due to fears of stigma, blame, judgement, poor treatment, or other repercussions. As a result, they often avoid, delay, or leave care, resulting in premature death and missed opportunities for care. Internationally, there have been concerted efforts to move towards patient-engaged research to enhance the quality of health care systems and services. In Canada, the Canadian Institutes of Health Research (CIHR) Strategy for Patient-Oriented Research (SPOR) initiative promotes engagement of patients as active partners in health care research. As part of a community based patient oriented research project, we critically analyze the SPOR framework to provide insights into what constitutes safer research with people who use(d) substances.

METHODS

We undertook a two-stage process that began with a review of community based research principles and the SPOR framework. At the second stage, we undertook a qualitative descriptive study employing focus groups to generate description of the adequacy and appropriateness of the SPOR framework for guiding research with people who use(d) substances on four key dimensions (patient engagement, guiding principles, core areas of engagement and benefits). The data were analyzed using qualitative content analysis to identify key issues and insights.

RESULTS

While the SPOR framework includes a range of patient roles, principles and areas for engagement, there are issues and gaps related to essential elements of safe patient-oriented research for people who use substances. These include an individualized focus on patients as partners, lack of recognition of community benefits, power imbalances and distrust due to systemic stigma, engagement as one way capacity building and learning, and lack of accountability for taking action on research findings.

CONCLUSIONS

Given the extent of stigma in health care and the ongoing illicit drug policy crisis, strategies for enhancing equitable Patient-Oriented Research (POR) include shifting language from patient partners to community researchers, recognizing power inequities and adding trust and equity as core POR principles including pay equity. Employing community based participatory research as a POR methodology allows the lead researchers to fully engage community throughout the research process, enhances community benefits and accountability for action.

Multi-level implementation factors that influence scale-up of methadone maintenance treatment in Moldovan prisons: A qualitative study

INTRODUCTION

People who inject drugs (PWID) are overrepresented in prison populations, especially in the Eastern European and Central Asian region (EECA), where HIV incidence and mortality continue to rise. Modeling data suggest that methadone maintenance treatment (MMT) scale-up in prison with continuation after release could substantially reduce new HIV infections. Moldova, one of four countries in the EECA to have introduced MMT in prisons, has faced challenges with its scale-up.

METHOD

To improve implementation of MMT in Moldovan prisoners, we analyzed the qualitative interviews of 44 recently released Moldovan prisoners with opioid use disorder who either accepted or rejected MMT while incarcerated; these 44 were among a subset of 56 participants in a quantitative survey who had complete interview data. After translating and back-translating interviews, we used content analysis to identify key barriers and facilitators to MMT uptake.

RESULTS

Our qualitative analyses revealed that positive attitudes toward methadone facilitated treatment uptake, yet the study identified three thematic barriers as to why PWID do not accept MMT while in prison, including: 1) negative personal attitudes toward MMT; 2) stigmatization of MMT by informal hierarchies within prison; and 3) distrust of the formal prison hierarchy (i.e., administration), which provides MMT.

CONCLUSION

Overall, the social forces of the two prisoner hierarchies and distrust between them appeared to outweigh the perceived benefits of MMT and impacted MMT uptake. Here we provide strategies to promote MMT more effectively in prison settings.

Dealing with low access to harm reduction: a qualitative study of the strategies and risk environments of people who use drugs in a small Swedish city

BACKGROUND

The development of harm reduction has been limited in many areas of Sweden. This study aims to understand the implications that this has for the life circumstances and risk management of people who use drugs in areas of low access.

METHODS

Eleven qualitative, semi-structured interviews were undertaken with people who use drugs in a small urban centre with no needle and syringe exchange program (NSP) or Housing First policy.

RESULTS

Participants reported many solutions to lack of NSP, including travel to an external NSP, creating bridging distribution networks, stealing, borrowing, reusing, ordering online, and smuggling injection equipment. They were at risk of having their equipment confiscated by police. Participants were mostly homeless, and to address exclusion from housing services, were forced to frequently find new temporary solutions, sheltering themselves in public places, with friends, in cars, among others. Participants felt the lack of services reflected stigmatized notions of drug use and heightened their exclusion from general society. For example, they avoided accessing other health care services for fear of discrimination. These issues caused high levels of stress and anxiety, in addition to serious risk for many somatic and psychological health conditions, including HIV and HCV transmission.

CONCLUSION

Lack of harm reduction services placed a great burden on study participants to develop strategies due to gaps in official programming. It also contributes to a vicious cycle of exclusion from services. The implementation of such evidence-based programs will reduce this burden, as well as provide the indirect, symbolic effect of inclusion.

Supportive environments during the substance use disorder epidemic in the rural United States: Provider support for interventions and expectations of interactions with providers

BACKGROUND

Harm reduction interventions, including SSP (Syringe Services Programs) and MAT (Medications for Addiction Treatment) have demonstrated the potential to help stem the epidemic of opioid use disorder. However, for that potential to be realized, people must expect that healthcare providers will be supportive if they ever seek care for substance use.

METHODS

This cross-sectional study investigated perceptions of provider support for SSP and MAT in the general population of 14 states selected specifically for 50 percent of the sample to include participants from rural counties with high rates of non-medical opioid use and injection. A survey of 3096 adults in 14 states and 675 counties within the Appalachian and Midwestern regions of the United States (collected between November of 2019 and May of 2020) examined the association between perceptions of provider support for harm reduction interventions, community members' trust of community healthcare providers, and expectations for patient-provider interactions involving disclosure of non-medical drug use.

RESULTS AND CONCLUSION

Path analysis supported the hypothesis that perceptions of provider support for harm reduction interventions predict positive expectations about patient-provider interactions and that trust in providers mediates this association. The model fit well among participants who reported past non-medical use of drugs and those who did not. In contrast to other research suggesting that trust in providers may be inconsequential during the initial stages of care, the current research suggests that trust may shape expectations about patient-provider interactions even before people use drugs. Communication of support for harm reduction interventions by providers may play an important role in promoting health care-seeking in populations that use drugs currently or who may use drugs in the future in high-risk rural areas of the United States.

Use of Pre-exposure Prophylaxis Among People Who Inject Drugs: Exploratory Findings of the Interaction Between Race, Homelessness, and Trust

Scale-up of pre-exposure prophylaxis (PrEP) in people who inject drugs (PWID) remains suboptimal. Patient-level factors are often complex and may contribute to scale-up. Using cross-sectional data from 234 opioid-dependent patients on methadone who met eligibility criteria for PrEP, we conducted logistic regression analyses to assess potential moderators associated with being on PrEP (n = 60). Mean provider trust was significantly higher among Blacks vs Whites (39.4 vs 34.9; p = 0.002) and non-homeless vs homeless participants (37.5 vs 34.8; p = 0.008). Though race/ethnicity was not a significant moderator on provider trust and PrEP use, increased provider trust was marginally associated with increased PrEP use among Blacks (p = 0.058). Additionally, homelessness significantly moderated provider trust and PrEP use (p = 0.024). Provider trust among non-homeless participants was positively correlated with PrEP use (p = 0.013) but not among homeless participants. Strategies that promote provider trust in Blacks and non-homeless PWID on methadone may improve PrEP scale-up.

Barriers to hepatitis C treatment among secondary needle and syringe program clients and opportunities to intervene

BACKGROUND

At least 160,000 Australians are living with hepatitis C (HCV), many of whom are people who inject drugs and access needle and syringe programs (NSP). Secondary NSPs provide injecting equipment via health services that are not dedicated to the provision of services to people who inject drugs; these sites could be a suitable space to increase engagement of people who inject drugs in HCV treatment. Drawing on data from a pilot study exploring the potential of upscaling linkage to HCV care in secondary NSPs, the aim of this research was to explore barriers and enablers to HCV treatment for clients who use these services.

METHODS

We interviewed 34 people who inject drugs (who self-reported HCV positivity) from six secondary NSPs in urban and regional Victoria, Australia in 2018. Fifty per cent were male, with ages ranging from 33 to 58. Twenty-two (65%) had never received HCV treatment and none had experience with direct-acting antiviral (DAA) treatment. Interviews were transcribed and analysed thematically. Field notes from a program evaluation with feedback from secondary NSP staff was also used as a secondary data source.

RESULTS

Five themes encompassing a set of contrasting barriers and enablers to accessing HCV care through secondary NSPs were uncovered. Themes included 'misinformation' vs. 'multiple trusted information sources; 'lack of symptoms and motivation' vs. 'benefits of cure'; 'competing priorities' vs. 'willingness and readiness to be cured'; 'unsupportive relationships with staff' vs. 'supportive relationships with staff'; and 'inaccessibility and stigma in health services' vs. 'enhanced support'. Secondary program evaluation data also highlighted that secondary NSP staff were under-resourced and had limited capacity to implement HCV care linkage and information.

CONCLUSION

We identified contrasting barriers and opportunities for accessing DAAs among a sample of secondary NSP clients and staff. Interventions that consider individual, provider and health system level factors are needed if secondary NSP services are to become a suitable setting to initiate conversations with clients around HCV treatment and provide linkages to care.

Does smoking impact trust in physicians and satisfaction with the health system in China?

INTRODUCTION

Trust and satisfaction play vital roles in how smokers react to smoking cessation treatment delivered by physicians. This paper aims to ascertain whether smoking status and pack-years of smoking affect trust in physicians and satisfaction with the health system in China.

METHODS

The current study used the ordered probit model to evaluate how smoking status affects trust in physicians and satisfaction with the health system in China. Data from the China Family Panel Studies (CFPS) 2018 were used for the analysis, and the final sample consisted of 29500 adults. The CFPS is a nationally representative, comprehensive, high-quality, biennial longitudinal survey of Chinese communities, families, and individuals. The survey was conducted in 25 provinces and their administrative equivalents. The population of 25 provinces represents 95% of the total population in Mainland China.

RESULTS

According to the ordered probit model, the results showed that current smokers were significantly negatively associated with trust in physicians, and more cigarette smoking was associated with decreased trust in physicians. Moreover, current smokers were also significantly negatively related to satisfaction with the health system.

CONCLUSIONS

The present study found that current smokers would be more likely to rate trust in physicians lower, and less likely to rate greater satisfaction with the health system, than never smokers. These results may have important implications for regaining trust in physicians from smokers and supporting health-system reform for tobacco treatment.

Opioid-Induced Hearing Loss and Neonatal Abstinence Syndrome: Clinical Considerations for Audiologists and Recommendations for Future Research

Purpose Over the last two decades, the number of Americans misusing opioids has reached epidemic levels. With such drastic increases in opioid misuse, audiologists are more likely to have patients with opioid-induced hearing loss or neonatal abstinence syndrome (NAS) than in previous years. More attention is needed on how these increases might influence clinical practice and such a discussion could be useful for audiologists. The goal of this article, therefore, is to summarize what is currently known regarding the relationship between opioid misuse and audiology to help guide hearing health care providers (with a particular focus on opioid-induced hearing loss and NAS). This article (a) summarizes the overlap in opioid misuse and hearing loss populations, (b) describes the evidence linking opioid misuse to hearing loss, (c) discusses clinical implications that opioid-induced hearing loss and NAS have for practicing audiologists, and (d) recommends directions for future audiological research on opioid-induced hearing loss and NAS. Conclusions There is considerable overlap between populations at-risk for hearing loss and opioid misuse. Additionally, compelling evidence exists linking opioid misuse to hearing loss, but the specific causal mechanisms remain unclear, indicating a need for additional research. This article attempts to fill a gap in the audiological literature and has the potential to serve as a guide for hearing health care providers to make more informed clinical decisions regarding patients with opioid-induced hearing loss and NAS. Clinicians may wish to consider the concerns raised in this article before intervening with such concerns, especially in the absence of best practice protocols.

Defining culturally safe primary care for people who use substances: a participatory concept mapping study

BACKGROUND

People who use substances experience high levels of substance-related stigma, both within and outside of health care settings, which can prevent people from help-seeking and contribute further to health inequities. Recognizing and respecting how political, social, economic, and historical conditions influence health and health care, cultural safety, with origins in addressing Indigenous racism, is a potential strategy for mitigating stigma and marginalization in health care. Using a participatory research approach, we applied the concept of cultural safety to develop a model of safe primary care from the perspective of people who use substances.

METHODS

People who use or used substances were involved in all phases of the research and led data collection. Study participants (n = 75) were 42.5 years old on average; half identified as female and one quarter as Indigenous. All were currently using or had previous experience with substances (alcohol and/or other drugs) and were recruited through two local peer-run support agencies. Concept mapping with hierarchical cluster analysis was used to develop the model of safe primary care, with data collected over three rounds of focus groups.

RESULTS

Participants identified 73 unique statements to complete the focus prompt: "I would feel safe going to the doctor if …" The final model consisted of 8 clusters that cover a wide range of topics, from being treated with respect and not being red-flagged for substance use, to preserving confidentiality, advocacy for good care and systems change, and appropriate accommodations for anxiety and the effects of poverty and criminalization.

CONCLUSIONS

Developing a definition of safe care (from the patient perspective) is the necessary first step in creating space for positive interactions and, in turn, improve care processes. This model provides numerous concrete suggestions for providers, as well as serving as starting point for the development of interventions designed to foster system change.

Awareness about and willingness to use long-acting injectable pre-exposure prophylaxis (LAI-PrEP) among people who use drugs

In the Bangkok Tenofovir Study of oral pre-exposure prophylaxis (PrEP; TDF/FTC), adherence was poor. Long-acting injectable pre-exposure prophylaxis (LAI-PrEP) for HIV prevention may help overcome adherence challenges and is currently being tested in clinical trials, but not in people who use drugs (PWUD), an important key population that remains highly vulnerable to HIV. Since PWUD are not currently included in trials of LAI-PrEP, we sought to examine awareness about LAI-PrEP and factors associated with willingness to use LAI-PrEP in this understudied population. Participants included 234 HIV-negative people with opioid use disorder and self-reported HIV-risk behaviors recruited from Connecticut's largest addiction treatment program. We analyzed data from a standardized assessment using audio computer-assisted self-interview (ACASI) to assess the independent factors associated with willingness to use LAI-PrEP. While only 25.6% of participants were aware of LAI-PrEP (67.1% had heard of oral PrEP), after being given a description of it, 73.5% were willing to use it, if it were available. Participants were most commonly concerned about long-term side effects (76.9%) of LAI-PrEP. Independent correlates of willingness to use LAI-PrEP were female sex (aOR = 2.181, p = 0.018), recent visit to healthcare provider (aOR = 2.9, p = 0.023), high perceived risk of acquiring HIV (aOR = 3.3, p = 0.007), and having previously taken oral PrEP (aOR = 3.284, p = 0.017). Findings suggest that PWUD are highly interested in PrEP, especially in LAI-PrEP formulations. Our results indicate the potential for LAI-PrEP, as an alternative to oral daily PrEP, to be implemented into existing evidence-based HIV-based HIV prevention efforts that target high-risk PWUD.

What is needed for implementing drug checking services in the context of the overdose crisis? A qualitative study to explore perspectives of potential service users

BACKGROUND

The current illicit drug overdose crisis within North America and other countries requires expanded and new responses to address unpredictable and potentially lethal substances, including fentanyl analogues, in the unregulated drug market. Community-wide drug checking is being increasingly explored as one such public health response. We explored how drug checking could be implemented as a potential harm reduction response to the overdose crisis, from the perspective of potential service users.

METHODS

The research was guided by the Consolidated Framework for Implementation Research (CFIR). We conducted a qualitative, pre-implementation study to inform development and implementation of drug checking services that are acceptable to people who use substances and meet their needs. University and community researchers conducted 27 in-depth interviews with potential service users at prospective drug checking sites. We inductively developed emerging themes to inform the implementation of drug checking services within the five domains of the CFIR, and identified the most relevant constructs.

RESULTS

Implementing community drug checking faces significant challenges within the current context of criminalization and stigmatization of substance use and people who use/sell drugs, and trauma experienced by potential service users. Participants identified significant risks in accessing drug checking, and that confidential and anonymous services are critical to address these. Engaging people with lived experience in the service can help establish trust. The relative advantage of drug checking needs to outweigh risks through provision of accurate results conveyed in a respectful, non-judgemental way. Drug checking should provide knowledge relevant to using and/or selling drugs and informing one's own harm reduction.

CONCLUSIONS

For service users, the extent to which the implementation of drug checking can respond to and mitigate the risks of being criminalized and stigmatized is critical to the acceptability and success of community drug checking. The culture and compatibility of the service, setting and staff with harm reduction principles and practices is essential.

Development of Best Practice Guidelines for Primary Care to Support Patients Who Use Substances

INTRODUCTION

People who use substances often mistrust the primary care system, impeding access.

OBJECTIVES

To build on research clarifying how to improve patients' feelings of safety, through co-creating best practice guidelines with physicians and patient representatives.

METHODS

After obtaining Research Ethics Board approval, this qualitative study engaged 22 participants including patients, physicians, and health system partners. We held a series of workshops, co-facilitated by patients and researchers, corresponding to 3 phases of the research: (1) establishment of cultural safety processes for participants during the workshops; (2) a facilitated, collaborative world café to develop guideline content; (3) validation of best practice guidelines. An implementation plan was developed and implemented. Finally, an external peer review was conducted by McGill University.

RESULTS

Best practices guidelines were developed giving the patient perspective on how to enhance primary care, as follows: (1) become trauma informed; (2) consider your clinical environment; (3) build a network; (4) supply an array of resources; (5) co-create a long-term treatment plan; (6) help me to stay healthy; (7) ensure timely access to specialized medical and surgical care; (8) be an advocate; (9) ask for feedback; (10) follow up. Resources were developed and disseminated.

CONCLUSION

The best practice guidelines reflect the patients' perspectives on common challenges patients have encountered, which impede their access to primary care. They support primary care physicians in providing more effective services to this challenging population of patients.

Physician Mistrust, Medical System Mistrust, and Perceived Discrimination: Associations with HIV Care Engagement and Viral Load

Medical mistrust is an important risk factor for many health outcomes. For individuals with HIV and substance use co-morbidities, mistrust may influence engagement with health care, and affect overall health and transmission risk. Medical mistrust can be measured by an individual's mistrust of his/her physician, or mistrust of the medical system. This study examined both types of mistrust among 801 substance-using individuals with uncontrolled HIV infection. The aims were to determine how physician mistrust, medical system mistrust, and discrimination experiences were associated with engagement in HIV primary care. Findings indicated higher levels of physician mistrust, but not medical system mistrust, were associated with a longer time since the last visit to an HIV provider. Longer time since seeing an HIV care provider was associated with higher viral load. This study refines our understanding of the relationship between mistrust and HIV care engagement for a large, diverse sample of substance-using individuals.

Short and sporadic injecting cessation episodes as predictors of incident hepatitis C virus infection: findings from a cohort study of people who inject drugs in Montréal, Canada

BACKGROUND AND AIMS

For most people who inject drugs (PWID), drug injecting follows a dynamic process characterized by transitions in and out of injecting. The objective of this investigation was to examine injecting cessation episodes of 1-3-month duration as predictors of hepatitis C virus (HCV) acquisition.

DESIGN

Cohort study.

SETTING

Montréal, Canada.

PARTICIPANTS

A total of 372 HCV-uninfected (HCV RNA-negative, HCV antibody-positive or -negative) PWID (mean age = 39.3 years, 82% male, 45% HCV antibody-positive) enrolled between March 2011 and June 2016.

MEASUREMENTS

At 3-month intervals, participants completed an interviewer-administered questionnaire and were tested for HCV particles (HCV RNA). At each visit, participants indicated whether they injected in each of the past 3 months (defined as three consecutive 30-day periods). Injecting cessation patterns were evaluated on a categorical scale: persistent injecting (no injecting cessation in the past 3 months), sporadic injecting cessation (injecting cessation in 1 of 3 or 2 of 3 months) and short injecting cessation (injecting cessation in 3 of 3 months). Their association with HCV infection risk was examined using Cox regression analyses with time-dependent covariates, including age, gender, incarceration, opioid agonist treatment and other addiction treatments.

FINDINGS

At baseline, 61, 26 and 13% of participants reported persistent injecting, sporadic injecting cessation and short injecting cessation, respectively. HCV incidence was 7.5 per 100 person-years [95% confidence interval (CI) = 5.9-9.5; 916 person-years of follow-up]. In adjusted Cox models, sporadic injecting cessation and short injecting cessation were associated with lower risks of incident HCV infection compared to persistent injecting (adjusted hazard ratios = 0.56, 95% CI = 0.30-1.04 and 0.24, 95% CI = 0.09-0.61), respectively.

CONCLUSION

Short and sporadic injecting cessation episodes were common among a cohort of people who inject drugs in Montréal, Canada. Injecting cessation episodes appear to be protective against hepatitis C virus acquisition, particularly when maintained for at least 3 months.

Strategies used by people who inject drugs to avoid stigma in healthcare settings

BACKGROUND

People who inject drugs (PWID) have limited engagement in healthcare services and report frequent experiences of stigma and mistreatment when accessing services. This paper explores the impact of stigma against injection drug use on healthcare utilization among PWID in the U.S. Northeast.

METHODS

We recruited PWID through community-based organizations (CBOs; e.g., syringe service programs). Participants completed brief surveys and semi-structured interviews lasting approximately 45 min exploring HIV risk behaviors and prevention needs. Thematic analysis examined the emergent topic of stigma experiences in relation to healthcare utilization.

RESULTS

Among 33 PWID (55% male; age range 24-62 years; 67% White; 24% Latino), most used heroin (94%) and injected at least daily (60%). Experiences of dehumanization in healthcare settings were common, with many participants perceiving that they had been treated unfairly or discriminated against due to their injection drug use. As participants anticipated this type of stigma from healthcare providers, they developed strategies to avoid it, including delaying presenting for healthcare, not disclosing drug use, downplaying pain, and seeking care elsewhere. In contrast to large institutional healthcare settings, participants described non-stigmatizing environments within CBOs, where they experienced greater acceptance, mutual respect, and stronger connections with staff.

CONCLUSIONS

Stigma against injection drug use carries important implications for PWID health. Increased provider training on addiction as a medical disorder could improve PWID healthcare experiences, and integrating health services into organizations frequented by PWID could increase utilization of health services by this population.

Correlates of Patterns of Health Values of African Americans Living With HIV/AIDS: Implications for Advance Care Planning and HIV Palliative Care

CONTEXT

Advance care planning rates remain low, especially among people who are HIV positive, disadvantaged, and African American. Although advance care planning can be a sensitive topic for clinicians and patients to discuss, health values clarification can be an important initial step.

OBJECTIVES

The purpose of the study was to explore health values of African Americans living with HIV/AIDS and to examine correlates of these values.

METHODS

Data were from the first 325 participants in the AFFIRM Care study, which enrolled adults living with HIV/AIDS in Baltimore, Maryland, who had histories of illicit drug use. Respondents were asked whether (yes/no) they thought any of six health states would be worse than death: severe unremitting pain, total dependency on others, irreversible coma, being on mechanical ventilation, nursing home residence, and severe dementia. Latent class analysis was used to group individuals by their pattern of responses, interpretable as preference for aggressive (life-sustaining) or nonaggressive (palliative) end-of-life care. Latent class regression analysis was used to examine associations between class membership and background, health status, and social variables.

RESULTS

We found statistical support for a three-class latent class analysis model: 1) the nonaggressive treatment class, comprising 43% of cases, in which members perceived that every state was worse than death; 2) the aggressive treatment class, comprising 33% of cases, in which members perceived that none of the states was worse than death; and 3) the mixed class (24% of cases), in which members perceived that only four of the six states were worse than death.

CONCLUSION

Three-quarters of participant response patterns had clear preferences for treatment decisions. Further research is needed to ensure inclusion of end-of-life scenarios relevant to this population.

"It's Not Much of a Life": The Benefits and Ethics of Using Life History Methods With People Who Inject Drugs in Qualitative Harm Reduction Research

A life history approach enables study of how risk or health protection is shaped by critical transitions and turning points in a life trajectory and in the context of social environment and time. We employed visual and narrative life history methods with people who inject drugs to explore how hepatitis C protection was enabled and maintained over the life course. We overview our methodological approach, with a focus on the ethics in practice of using life history timelines and life-grids with 37 participants. The life-grid evoked mixed emotions for participants: pleasure in receiving a personalized visual history and pain elicited by its contents. A minority managed this pain with additional heroin use. The methodological benefits of using life history methods and visual aids have been extensively reported. Crucial to consider are the ethical implications of this process, particularly for people who lack socially ascribed markers of a "successful life."

"Until people start dying in droves, no actions will be taken": perception and experience of HIV-preventive measures among people who inject drugs in northwestern Russia

Background

The HIV epidemic among people who inject drugs (PWID) in Russia continues to spread. This exploratory study examines how HIV-prevention measures are perceived and experienced by PWID in the northwestern region of Russia.

Methods

Purposive sampling was used to obtain a variety of cases that could reflect possible differences in perception and experience of HIV-prevention efforts. We conducted 22 semi-structured interviews with PWID residing in the Arkhangelsk and St. Petersburg regions.

Results

The main sources of prevention information on HIV for PWID were media campaigns directed to the general population. These campaigns were effective with regard to communicating general knowledge on HIV but were ineffective in terms of risk behavior change. The subjects generally had trust in medical professionals and their advice but did not follow prevention recommendations. Most informants had no or very little prior contact with harm reduction services. On the level of attitudes towards HIV prevention efforts, we discovered three types of fatalism among PWID: “personal fatalism” - uselessness of HIV prevention efforts, if one uses drugs; “prevention-related fatalism” - prevention programs are low effective, because people do not pay attention to them before they get infected; “state-related fatalism” – the lack of belief that the state is concerned with HIV prevention issues. Despite this fatalism the participants opined that NGOs would do a better job than the state as they are “really working” with risk groups.

Conclusions

As HIV prevention campaigns targeted at the general population and prevention advice received from medical professionals are not sufficiently effective for PWID in terms of risk behavior change, prevention programs, such as community-based and peer-based interventions specifically tailored to the needs of PWID are needed, which can be achieved by a large expansion of harm reduction services in the region. Personal communication should be a crucial element in such interventions in addition to harm reduction materials provision. Training programs, peer outreach, and culture-change interventions which try to alter widespread fatalistic norms or attitudes towards their health are especially needed, since this study indicates that fatalism is a major barrier for behavior change.

Access to healthcare insurance and healthcare services among syringe exchange program clients in Massachusetts: qualitative findings from health navigators with the iDU ("I do") Care Collaborative

BACKGROUND

Little is known about access to health insurance among people who inject drugs (PWID) who attend syringe exchange programs (SEPs). The goal of the current study was to assess perceptions of SEP staff, including health navigators and program managers, on access to health insurance and healthcare access among SEP clients following implementation of state and federal policies to enhance universal healthcare access in Massachusetts.

METHODS

Between December 2014 and January 2015, we conducted in-depth interviews (n = 14) with SEP staff, including both program managers and health navigators, to assess knowledge, attitudes, and beliefs related to health insurance enrollment and access to enhanced referrals among SEP clients. We developed a preliminary coding scheme from the interview guide and used a grounded theory approach to guide inclusion of subsequent thematic codes that emanated from the data. We analyzed the coded data thematically in an iterative fashion using a consensus-based approach.

RESULTS

We identified five primary themes that emerged from the qualitative interviews, including high levels of health insurance enrollment among SEP clients; barriers to enrolling in health insurance; highly needed referrals to services, including improved access to substance use disorder treatment and hepatitis C virus treatment; barriers to referring clients to these highly needed services; and recommendations for policy change.

CONCLUSIONS

While barriers to enrollment and highly needed referrals remain, access to and enrollment in healthcare insurance plans among PWID at SEPs in Massachusetts are high. With the uncertain stability of the Affordable Care Act following the US presidential election of 2016, our findings summarize the opportunities and challenges that are connected to health insurance and healthcare access in Massachusetts. SEPs can play an important role in facilitating access to health insurance and enhancing access to preventive health and primary care.

Harm Reduction and Tensions in Trust and Distrust in a Mental Health Service: A Qualitative Approach

BACKGROUND

People seeking care for substance use (PSCSU) experience deep social and health inequities. Harm reduction can be a moral imperative to approach these persons. The purpose of this study was to explore relationships among users, health care providers, relatives, and society regarding harm reduction in mental health care, using a trust approach rooted in feminist ethics.

METHODS

A qualitative study was conducted in a mental health service for PSCSU, and included fifteen participants who were health care providers, users, and their relatives. Individual in-depth and group interviews, participant observation, and a review of patients' records and service reports were conducted.

RESULTS

Three nested levels of (dis)trust were identified: (dis)trust in the treatment, (dis)trust in the user, and self-(dis)trust of the user, revealing the interconnections among different layers of trust. (Dis)trust at each level can amplify or decrease the potential for a positive therapeutic response in users, their relatives' support, and how professionals act and build innovations in care. Distrust was more abundant than trust in participants' reports, revealing the fragility of trust and the focus on abstinence within this setting.

CONCLUSION

The mismatch between wants and needs of users and the expectations and requirements of a society and mental health care system based on a logic of "fixing" has contributed to distrust and stigma. Therefore, we recommend policies that increase the investment in harm reduction education and practice that target service providers, PSCSU, and society to change the context of distrust identified.

Spillover effects of HIV testing policies: changes in HIV testing guidelines and HCV testing practices in drug treatment programs in the United States

BACKGROUND

To examine the extent to which state adoption of the Centers for Disease Control and Prevention (CDC) 2006 revisions to adult and adolescent HIV testing guidelines is associated with availability of other important prevention and medical services. We hypothesized that in states where the pretest counseling requirement for HIV testing was dropped from state legislation, substance use disorder treatment programs would have higher availability of HCV testing services than in states that had maintained this requirement.

METHODS

We analyzed a nationally representative sample of 383 opioid treatment programs from the 2005 and 2011 National Drug Abuse Treatment System Survey (NDATSS). Data were collected from program directors and clinical supervisors through telephone surveys. Multivariate logistic regression models were used to measure associations between state adoption of CDC recommended guidelines for HIV pretest counseling and availability of HCV testing services.

RESULTS

The effects of HIV testing legislative changes on HCV testing practices varied by type of opioid treatment program. In states that had removed the requirement for HIV pretest counseling, buprenorphine-only programs were more likely to offer HCV testing to their patients. The positive spillover effect of HIV pretest counseling policies, however, did not extend to methadone programs and did not translate into increased availability of on-site HCV testing in either program type.

CONCLUSIONS

Our findings highlight potential positive spillover effects of HIV testing policies on HCV testing practices. They also suggest that maximizing the benefits of HIV policies may require other initiatives, including resources and programmatic efforts that support systematic integration with other services and effective implementation.

Does distrust in providers affect health-care utilization in China?

How trust affects health-care utilization is not well-understood, especially in low- and middle-income countries. This article focuses on China, a middle-income country where low trust in health-care settings has become a prominent issue, but actual levels of distrust and their implications for utilization are unknown. We conducted a nationally representative survey of the Chinese population (November 2012 to January 2013), which resulted in a sample of 3680 adult men and women. Respondents rated their trust in different types of health-care providers. Using multivariate logistic and negative binomial regression models, we estimated the association between distrust in clinics and respondents' hospital visits in the last year; whether they had sought hospital treatment first for two common symptoms (headache, cold) in the last 2 months; and whether they said they would go first to a hospital if they had a minor or major illness. We analysed these associations before and after adjusting for performance evaluations of clinics and hospitals, controlling for sex, age, education, income, insurance status, household registration and self-assessed health. We found that distrust in hospitals is low, but distrust in clinics is high and strongly associated with increased hospital utilization, especially for minor symptoms and illnesses. Further research is needed to understand the reasons for distrust in clinics because its effects are not fully accounted for by poor evaluations of their competence.

Visits to primary care physicians among persons who inject drugs at high risk of hepatitis C virus infection: room for improvement

The role of primary care physicians (PCP) in hepatitis C virus (HCV) prevention is increasingly emphasized. Yet, little is known about the patterns of contacts with PCP among persons who inject drugs (PWID). We sought to assess the 6-month prevalence of PCP visiting among PWID at risk of HCV infection and to explore the associated factors. Baseline data were collected from HCV-seronegative PWID recruited in HEPCO, an observational Hepatitis Cohort study (2004-2011) in Montreal, Canada. An interviewer-administered questionnaire elicited information on socio-demographic factors, drug use patterns and healthcare services utilization. Blood samples were tested for HCV antibodies. Using the Gelberg-Andersen Behavioral Model, hierarchical logistic regression analyses were conducted to identify predisposing, need and enabling factors associated with PCP visiting. Of the 349 participants (mean age = 34; 80.8% male), 32.1% reported visiting a PCP. In the multivariate model, among predisposing factors, male gender [adjusted odds ratio (AOR) = 0.45 (0.25-0.83)], chronic homelessness [AOR = 0.08 (0.01-0.67)], cocaine injection [AOR = 0.46 (0.28-0.76)] and reporting greater illegal or semi-legal income [AOR = 0.48 (0.27-0.85)] were negatively associated with PCP visits. Markers of need were not associated with the outcome. Among enabling factors, contact with street nurses [AOR = 3.86 (1.49-9.90)] and food banks [AOR = 2.01 (1.20-3.37)] was positively associated with PCP visiting. Only one third of participating PWID reported a recent visit to a PCP. While a host of predisposing factors seems to hamper timely contacts with PCP among high-risk PWID, community-based support services may play an important role in initiating dialogue with primary healthcare services in this population.

Trust and people who inject drugs: The perspectives of clients and staff of Needle Syringe Programs

AIMS

Interest in health-care related trust is growing with the recognition that trust is essential for effective therapeutic encounters. While most trust-related research has been conducted with general patient groups, the experiences of people who inject drugs cannot be understood without acknowledging the critical role social stigma plays in shaping (mis)trust, both generally and in regards to health services specifically. This study examined the experiences of trust among clients and staff of Needle and Syringe Programs (NSPs) in one area of Sydney, Australia.

METHOD

In-depth interviews with 12 NSP staff and 31 NSP clients were conducted. Analysis was informed by a five component model of trust, with particular emphasis on the notion of "global trust" as encompassing experiences of stigma and other negative social processes related to injecting drug use. Participant experiences of trust in NSPs were compared with those within other drug-related health services. Particular attention was paid to understanding the relationship between 'identity' (as a drug user) and 'legitimacy' (as a service user) and the centrality of this relationship to the experience of global trust for PWID.

RESULTS

Notions of identity and legitimacy were inextricably bound up with the stigmatisation of drug use, shaping participants' experiences and accounts of trust in NSPs and drug treatment services. Client participants reported high levels of trust in NSPs, especially when compared with drug treatment services, describing being treated like "any other person" even when negotiating 'sensitive' issues. NSP staff participants described the establishment of trust as not only underpinning their work with clients but as something that required ongoing renewal and demonstration.

CONCLUSION

"Global trust" assists us to better understand the complex experiences shaping PWID decisions to engage with and trust health services. The high levels of trust reported between client and NSP need to be recognised as a valuable resource for the delivery of effective health care for people who inject drugs, including encouraging behaviours to support the prevention of blood-borne viruses.

Challenges in managing HIV in people who use drugs

PURPOSE OF REVIEW

HIV management in people who use drugs (PWUD) is typically complex and challenging due to the presence of multiple medical and psychiatric comorbidities as well as social, physical, economic and legal factors that often disrupt the HIV continuum of care. In this review, we describe the individual, health systems and societal barriers to HIV treatment access and care retention for PWUD. In addition, the clinical management of HIV-infected PWUD is often complicated by the presence of multiple infectious and noninfectious comorbidities.

RECENT FINDINGS

Improved HIV treatment outcomes can be enhanced through improved testing and linkage strategies along with better treatment retention and antiretroviral (ART) adherence. Improved ART adherence can be achieved through the provision of opioid substitution therapy (OST), directly administered ART (DAART) and integration of ART with OST services. Recent advances with direct-acting antivirals (DAAs) for hepatitis C virus (HCV) have shown superior outcomes than interferon-based regimes in HIV-HCV coinfected patients. Newer diagnostic technologies for tuberculosis (TB) hold promise for earlier diagnosis for PWUD coinfected with TB, and TB treatment outcomes are improved through combination with OST.

SUMMARY

HIV-infected PWUDs are a key population who frequently experience suboptimal outcomes along the HIV continuum of care. A comprehensive strategy that encompasses evidence-based prevention and treatment interventions that target the individual, family, healthcare system, legal and societal structure is required to ensure greater participation and success in HIV treatment and care.

Effect of social relationships on antiretroviral medication adherence for people living with HIV and substance use disorders and transitioning from prison

BACKGROUND

This paper examines how family and social relations facilitate and inhibit adherence to antiretroviraltherapy (ART) for people living with HIV (PLH) who have underlying substance use disorders and are transitioningto the community post-incarceration.

METHODS

Combining the methods of inductive close reading and constantcomparison, we analyzed the data from 30 semi-structured interviews of PLH who had recently transitioned to thecommunity within the previous 90 days.

RESULTS

Three central themes were anticipated as important socialrelationships post-release: self-reported family, friends and clinicians. Among these, four sub-themes (social isolation, 'double jeopardy', search for belonging, and trust and respect) emerged, highlighting how they impacted ART adherence. Post-release, participants returned to resource-poor communities where they experienced socialisolation. ART adherence was enabled by having a purpose in life, which correlated with having robust family support structures. Many former prisoners felt that a chasm between them and their families existed, both because of HIV stigma and their addiction problems. In this context, relationships with untrustworthy friends from their druguse networks led to relapse of drug use and risky behaviors, jeopardizing participants' ART adherence and persistence. To avoid the double jeopardy, defined as seeking friends for support but who were also the ones who contributed to drug relapse, participants searched for new social anchors, which often included their healthcare providers who represented trusted and respected persons in their life.

CONCLUSIONS

While some former prisonersperceived doctors as uncaring and their relationships asymmetrical, positive relationships with these providers,when respect and trust was mutual, reinforced the participants' sense of belonging to what they called 'the world that don't do drugs' and motivated them to adhere to ART.

The double-edged sword of electronic health records: implications for patient disclosure

Objective Electronic health record (EHR) systems are linked to improvements in quality of care, yet also privacy and security risks. Results from research studies are mixed about whether patients withhold personal information from their providers to protect against the perceived EHR privacy and security risks. This study seeks to reconcile the mixed findings by focusing on whether accounting for patients’ global ratings of care reveals a relationship between EHR provider-use and patient non-disclosure.

Materials and methods A nationally representative sample from the 2012 Health Information National Trends Survey was analyzed using bivariate and multivariable logit regressions to examine whether global ratings of care suppress the relationship between EHR provider-use and patient non-disclosure.

Results 13% of respondents reported having ever withheld information from a provider because of privacy/security concerns. Bivariate analysis showed that withholding information was unrelated to whether respondents’ providers used an EHR. Multivariable analysis showed that accounting for respondents’ global ratings of care revealed a positive relationship between having a provider who uses an EHR and withholding information.

Discussion After accounting for global ratings of care, findings suggest that patients may non-disclose to providers to protect against the perceived EHR privacy and security risks. Despite evidence that EHRs inhibit patient disclosure, their advantages for promoting quality of care may outweigh the drawbacks.

Conclusions Clinicians should leverage the EHR's value in quality of care and discuss patients’ privacy concerns during clinic visits, while policy makers should consider how to address the real and perceived privacy and security risks of EHRs.

A cross-sectional study describing factors associated with utilisation of GP services by a cohort of people who inject drugs

Background

People who inject drugs (PWID) use healthcare services, including primary care, at a disproportionately high rate. We investigated key correlates of general practitioner (GP) related service utilisation within a cohort of PWID.

Methods

Using baseline data from a cohort of 645 community-recruited PWID based in Melbourne, Victoria, we conducted a secondary analysis of associations between past month use of GP services unrelated to opioid substitution therapy (OST) and socio-demographic and drug use characteristics and self-reported health using multivariate logistic regression.

Results

Just under one-third (29%) of PWID had accessed GP services in the month prior to being surveyed. Participants who reported living with children (adjusted odds ratio, AOR 1.97, 95% CI 1.04 - 3.73) or having had contact with a social worker in the past month (AOR 1.92, 95% CI 1.24 - 2.98) were more likely to have seen a GP in the past month. Participants who were injecting daily or more frequently (AOR 0.50, 95% CI 0.30 - 0.83) or had a weekly income of less than $400 (AOR 0.59, 95% CI 0.38 - 0.91) were less likely to report having seen a GP in the past month.

Conclusions

Our sample frequently attended GP services for health needs unrelated to OST. Findings highlight both the characteristics of PWID accessing GP services and also those potentially missing out on primary care and preventive services.

Self-management of buprenorphine/naloxone among online discussion board users

BACKGROUND

Buprenorphine/naloxone is an effective medication used to treat opioid dependence. Patients in treatment and those using it illegally without prescriptions have discussed using buprenorphine/naloxone anonymously on Internet discussion boards. Their beliefs about self-treatment and efforts to self-treat are not well known.

OBJECTIVES

To identify facilitators of self-treatment by online buprenorphine/naloxone users.

METHODS

A qualitative, retrospective study of discussion board postings from September 2010 to November 2012 analyzed 121 threads from 13 discussion boards using grounded theory.

RESULTS

Facilitators of self-management themes that emerged included: (1) a ready supply of buprenorphine/naloxone from a variety of sources; (2) distrust of buprenorphine prescribers and pharmaceutical companies; (3) the declaration that buprenorphine/naloxone is a "bad-tasting" medicine; (4) the desire to adopt a different delivery method other than sublingually; and (5) a desire to become completely "substance-free." The sublingual film formulation appears to be an important facilitator in self-treatment because it can more easily be apportioned to extend the medication because of limited supply, cost, or to taper. CONCLUSIONS/IMPORTANCE: The findings indicate a range of self-management activities ranging from altering the amount taken to modifying the physical medication composition or changing the administration route; some of these behaviors constitute problematic extra-medical use. Contributors to discussion boards seem to trust each other more than they trust pharmacists and prescribing physicians. The shared knowledge and behaviors of this understudied online community are important to healthcare providers because of the previously unknown precautions and risks taken to self-treat.

What's the Cost of Finding the Right Fit? The Cost of Conducting NSP Business in a Range of Modalities

The aim of this study was to calculate the cost of a range of needle and syringe program (NSP) models to contribute to planning for effective NSP delivery. Existing health service data was used to estimate the cost per needle distributed across four modes of service delivery (Primary NSP, including one model of Primary NSP providing primary health care; Secondary NSP; Vending Machine and Outreach) over three years. Costs were primarily affected by the ratio of the volume of equipment distributed to staff costs. The average cost per unit for Primary, Secondary and Outreach modes was approximately $1.00. The cost for Vending Machine provision (accounting for income from service users) was the cheapest option at $0.30–0.40 per unit. When income from services users are not included in calculations, other considerations may be more important than cost when making decisions about providing access to NSP services to a marginalized client group with diverse needs.

Understanding barriers to hepatitis C virus care and stigmatization from a social perspective

A large body of literature emphasizes the relationship between stigma and adverse health outcomes and health access measures. For people living with hepatitis C virus (HCV), stigma is a defining feature given the association of HCV with the socially demonized practice of injection drug use. However, there is little literature that specifically examines stigma as a barrier to HCV care and treatment. This review argues that the relationship between the person living with HCV and their health worker can work to ameliorate the effects of stigma. We draw on an emerging literature that examines the positive association between a patient's "trust" in their health worker and outcomes such as increased healthcare utilization and reduced risk behaviors. We investigate a growing body of health services research that acknowledges the importance of stigma and demonstrates ways to build positive, enabling relationships between patient, health worker, and health setting.

Taming systems to create enabling environments for HCV treatment: negotiating trust in the drug and alcohol setting

HCV (hepatitis C) treatment uptake among the population most affected - people who inject drugs - is suboptimal. Hospital based treatment provision is one evidenced barrier to HCV treatment uptake. In response, HCV treatment is increasingly located in treatment settings seen as more amenable to people who inject drugs, such as drug and alcohol services. We explored the accessibility of HCV treatment provision at two such partnerships. Data collection comprised qualitative interviews collected in 2011 and 2012 with 35 service users and 14 service providers of HCV treatment in London, United Kingdom. We draw here primarily on thematic analyses of service provider accounts, yet narratives relating to trust and environment emerged unsolicited in both user and provider accounts of negotiated HCV treatment access. A key theme in service provider accounts were strategies they deployed to 'tame' the treatment system so as to create an 'enabling environment' of care, in which trust was a critical feature. This 'taming' of the system was enacted through practices of 'negotiated flexibility', including in relation to appointments, eligibility, and phlebotomy. Service user accounts accentuated familiar environments and known health providers as those most trusted, and the potentially stigmatising effects of negotiating treatment in unfamiliar territory, especially hospital settings. Whilst noting the effects of provider strategies to negotiate flexibility on behalf of would-be patients seeking treatment, we conclude by noting the limits of trust relations in settings of constrained choice.

Women's Health Care Utilization among Harder-to-Reach HIV-Infected Women ever on Antiretroviral Therapy in British Columbia

Background. HIV-infected women are disproportionately burdened by gynaecological complications, psychological disorders, and certain sexually transmitted infections that may not be adequately addressed by HIV-specific care. We estimate the prevalence and covariates of women's health care (WHC) utilization among harder-to-reach, treatment-experienced HIV-infected women in British Columbia (BC), Canada. Methods. We used survey data from 231 HIV-infected, treatment-experienced women enrolled in the Longitudinal Investigations into Supportive and Ancillary Health Services (LISA) study, which recruited harder-to-reach populations, including aboriginal people and individuals using injection drugs. Independent covariates of interest included sociodemographic, psychosocial, behavioural, individual health status, structural factors, and HIV clinical variables. Logistic regression was used to generate adjusted estimates of associations between use of WHC and covariates of interest. Results. Overall, 77% of women reported regularly utilizing WHC. WHC utilization varied significantly by region of residence (P value <0.01). In addition, women with lower annual income (AOR (95% CI) = 0.14 (0.04–0.54)), who used illicit drugs (AOR (95% CI) = 0.42 (0.19–0.92)) and who had lower provider trust (AOR (95% CI) = 0.97 (0.95–0.99)), were significantly less likely to report using WHC. Conclusion. A health service gap exists along geographical and social axes for harder-to-reach HIV-infected women in BC. Women-centered WHC and HIV-specific care should be streamlined and integrated to better address women's holistic health.

Relying on Injection Drug Users to Access and Adhere to HIV Therapeutics

Results are presented of enrolling HIV+ active-injection drug users (IDUs) into a peer-driven intervention (PDI) to improve their adherence to medical care. Using respondent-driven sampling (RDS), which evolved out of the PDI model, the authors recruited and tested 1,097 IDUs, of whom 145 were confirmed to be HIV+. Despite promises of confidentiality, increased social supports, and direct cash rewards for participating, only 78 (54%) of the HIV+ IDUs enrolled in the subsequent adherence study. Correlates of participation as well as interviews with respondents who declined participating are presented. The seemingly negative findings have important implications for future adherence studies. RDS provided a powerful mechanism for recruiting HIV+ IDUs. But selection biases were revealed to favor sicker yet more socially connected respondents, which resulted in more conservative outcomes with regard to social supports and positive health-seeking behaviors. The analysis may help streamline future efforts using the PDI, which harnesses IDUs’ abilities to help one another, by underscoring some of the mechanism’s limitations.

Substance abuse, violence, and HIV in women: a literature review of the syndemic

Women in the United States are increasingly affected by HIV/AIDS. The SAVA syndemic-synergistic epidemics of substance abuse, violence, and HIV/AIDS-is highly prevalent among impoverished urban women and potentially associated with poor HIV outcomes. A review of the existing literature found 45 articles that examine SAVA's impact on (1) HIV-associated risk-taking behaviors, (2) mental health, (3) healthcare utilization and medication adherence, and (4) the bidirectional relationship between violence and HIV status. Overall, results confirm the profound impact of violence and victimization and how it is intertwined with poor decision making, increased risk taking and negative health consequences, particularly in the context of substance abuse. Among current findings, there remain diverse and inconsistent definitions for substance abuse, violence, mental illness, adherence, and healthcare utilization that confound interpretation of data. Future studies require standardization and operationalization of definitions for these terms. Development and adaptation of evidence-based interventions that incorporate prevention of violence and management of victimization to target this vulnerable group of women and thereby promote better health outcomes are urgently needed.

An integrated supervised injecting program within a care facility for HIV-positive individuals: a qualitative evaluation

While there has been growing interest in comprehensive models of treatment and care for individuals living with HIV/AIDS, little attention has been given to the potential role that supervised injecting programs could play in increasing access to prevention and care services for HIV-positive injection drug users (IDU). We conducted 22 semi-structured interviews with HIV-positive IDU regarding a supervised injection program integrated in an HIV focused care facility known as the Dr. Peter Centre (DPC). We also interviewed seven staff members who supervise injections within the facility. All interviews were audio recorded, transcribed verbatim, and a thematic analysis was conducted. Participant and staff reports indicated that the integrated supervised injection program influenced IDUs' access to care by building more open and trusting relationships with staff, facilitating engagement in safer injection education and improving the management of injection-related infections. Participants and staff viewed the program as facilitating the delivery of care through mediating overdose risks, reducing the need to punitively manage drug use on-site and reducing the risks of encountering used syringes on the premises. For some participants, however, feelings of shame and fear of judgment in relation to their drug use limited initial uptake of the program. Our findings identify mechanisms through which integrated supervised injection programs may serve to better facilitate access and delivery of comprehensive care for HIV-positive IDU and highlight the benefits of addressing HIV-positive IDUs' drug use in the context of comprehensive models of healthcare.
