Predictors of health care workers' support for discriminatory treatment and care of people who inject drugs

Provider Implicit Bias in Prescribing HIV Pre-exposure Prophylaxis (PrEP) to People Who Inject Drugs

BACKGROUND

Multiple HIV outbreaks among people who inject drugs (PWIDs) have occurred in the USA since 2015, highlighting the need for additional HIV prevention tools. Despite high levels of need, pre-exposure prophylaxis (PrEP) is drastically underutilized among PWIDs. Implicit bias toward PWID held by clinicians may impede PrEP scale-up among these underserved patients. This study examined how primary care providers' (PCPs) clinical decisions related to PrEP can be impacted by biases when the patient has a history of substance use.

METHODS

We conducted an online survey of PCPs (n = 208). The survey included the implicit association test (IAT) to assess unconscious attitudes toward PWIDs, direct questions regarding clinicians' explicit PWID attitudes, and an embedded experiment in which we systematically varied the risk behavior of a hypothetical patient and asked PCPs to make clinical judgments.

RESULTS

A minority (32%) of PCPs reported explicit PWID bias. The IAT indicated strong implicit PWID bias (meant IAT score = 0.59, p < .0001) among 88% of the sample. Only 9% of PCPs had no implicit or explicit PWID bias. PWID patients were judged as less likely to adhere to a PrEP regimen, less responsible, and less HIV safety conscious than heterosexual or gay male patients. Anticipated lack of adherence mediated PCPs' intent to prescribe PrEP to PWID.

CONCLUSIONS

PCPs' bias may contribute to PrEP being under-prescribed to PWID. Implicit and explicit PWID biases were common in our sample. This study illustrates the need to develop and test tailored interventions to decrease biases against PWID in primary care settings.

Reducing stigma towards people living with HIV and people who inject drugs using social norms theory: An online study with Australian health care workers

BACKGROUND

Despite extensive evidence regarding the negative effects of stigma experienced by people living with HIV (PLHIV) and people who inject drugs within health care settings, comparatively little evidence exists regarding the effectiveness of initiatives to reduce this stigma.

METHOD

This study developed and assessed brief online interventions based on social norms theory with a sample of Australian health care workers (n=653). Participants were randomly allocated to either 1) HIV intervention group, or 2) injecting drug use intervention group. They completed baseline measures of their attitudes towards either PLHIV or people who inject drugs, matching measures of their perceptions of their colleagues' attitudes, plus a series of items reflecting behavioural intentions and agreement with stigmatising behaviour towards PLHIV or people who inject drugs. Participants were presented with a social norms video before completing the measures again.

RESULTS

At baseline, participants' agreement with stigmatising behaviour was correlated with their perceptions of how many of their colleagues would agree. After watching the video, participants reported more positive perceptions of their colleagues' attitudes towards PLHIV and people who inject drugs, as well as more positive personal attitudes towards people who inject drugs. Changes in perceptions of colleagues' support for stigmatising behaviour independently predicted changes in participants' personal agreement with that behaviour.

CONCLUSION

Findings suggest that interventions based on social norms theory that address health care workers' perceptions of their colleagues' attitudes can play an important role in contributing to broader initiatives to reduce stigma in health care settings.

The freighted social histories of HIV and hepatitis C: exploring service providers' perspectives on stigma in the current epidemics

A virus has a social history. In the case of the hepatitis C virus (HCV) and HIV, this history is one involving stigma and discrimination, advocacy and activism, and recent dramatic improvements in treatment. These social histories influence the experience of people who live with the viruses, and those who work with them. One aspect of this is the impact of social changes on the biographical disruption and integration brought about by illness. Healthcare practitioners who see significant improvements in the effectiveness of treatment for a condition over the course of their professional life will incorporate those changes into their own history and their relationship to that condition.This article is based on a study of the experiences of serodiscordance, or mixed infection status, in families living with HIV and two types of viral hepatitis, hepatitis B and hepatitis C. The article explores the perspectives of healthcare workers who work with people affected by these viruses, who were asked about their experiences in working with serodiscordance in families. Interviews revealed that changing social meanings given to bloodborne viruses, and changes to treatment over time, held a significant place in the accounts that service providers gave of their work. In asking them to describe their work with HIV and HCV, we were also asking about work that has been shaped by changing patterns and sources of stigma, and recently reshaped by changes in treatment and outcomes. While typically the experiences of patients and their families are used to investigate the social histories of diagnosis and stigma, the professional perspectives and life stories of the service providers who work with them are also revealing. We heard accounts in which histories as well as current regimes were prominent, illuminated further by insights from the sociology of health on narrative and biographical disruption.

Putting out the welcome mat-A qualitative exploration of service delivery processes and procedures as barriers to treatment-seeking for people who use alcohol and other drugs

INTRODUCTION

There are a range of models and structures that determine features of alcohol and other drug treatment. Despite some structures being long-established, less is known about how specific aspects of service delivery impact treatment-seeking for people who use alcohol and other drugs. This Australian qualitative study explored both people with lived experience of problematic alcohol and other drug use, and health care staff's experiences of service delivery.

METHODS

Thirty-nine semi-structured interviews with people with lived experience and staff from either alcohol and other drug specialist, or broader health-care services, explored experiences of service delivery processes and procedures. Transcripts were thematically analysed and guided by a broad interest in barriers to treatment-seeking.

RESULTS

Within alcohol and other drug specialist services (i) time spent on wait lists; and (ii) poor implementation of assessment processes were identified barriers to treatment-seeking and engagement. Within broader health-care services (i) organisational expectations around behaviour and engagement; (ii) alcohol and other drugs viewed as separate to service role; and (iii) limited opportunities to informally engage were identified barriers to treatment-seeking.

DISCUSSION AND CONCLUSIONS

Results suggest opportunities to engage and undertake needs-based care planning are yet to be fully realised, particularly at the intake and assessment stages of alcohol and other drug service delivery; with frequent reassessment resulting in people repeatedly recounting traumatic experiences, often to different people, only to be placed back on wait lists with no support. Within broader health-care services aspects of service delivery may perpetuate stigma that places such people outside the purview of health care.

Attitudes of health professionals towards people with substance use disorders in Brazil, controlling for the effects of social desirability

Health professionals are in a strategic position to help people with substance use disorders (SUDs) who seek health services for support or treatment. However, it is known that professionals' attitudes towards people who use alcohol and other drugs are marked by stigmatizing attitudes that create barriers to access quality treatment and make it difficult for the user to adhere to it. From this, the present study aimed to investigate the attitudes of 264 health professionals from specialised services and primary health care (PHC) in the Southeast region of Brazil, through Opening Minds Scale for Healthcare Providers (OMS-HC), taking into account the hypothesis of contact with the subject as a predictor of more positive attitudes. For this, a Multiple Hierarchical Regression was carried out to ascertain the contribution of the variables used in the explanatory model of attitudes. In addition, the measure of social desirability (SD), assessed by Brazilian Portuguese adaptation of Marlowe-Crowne Social Desirability Scale, was used as a control variable in the regression model to obtain a more robust and accurate model regarding the presence of biased responses, pervasive in studies on attitudes. In general, our findings showed that contact/familiarity with substance use, either through direct contact with users or through the respondent's own use, predicted more positive attitudes, with specialised service professionals expressing more positive attitudes than those working in PHC. Blaming the user for his/her condition presented itself as a predictor of more negative attitudes. Studies like this are of paramount importance for understanding the relationship established between professionals and service users and, therefore, for tailoring interventions and programs that aim to reduce stigmatizing attitudes and provide better access to health for people with SUDs. The importance of using the SD measure as a control variable in Regression is also emphasised, as an effective way to overcome to a common limitation in studies of attitudes.

Australian health and medical workers' concerns around providing care to people living with hepatitis B

There is established literature on health workers' attitudes towards working with people living with stigmatised health conditions and behaviours, such as HIV, hepatitis C and injecting drug use. Less is known about health workers' attitudes and concerns around providing care to people living with hepatitis B virus (HBV), which is concerning as research indicates that negative attitudes may impact on the quality of care provided to these populations, with adverse health outcomes for clients. The aim of this paper is to examine health and medical workers' concerns about providing care to people living with HBV, and the factors that may influence these concerns. Australian health and medical workers (n = 551) completed an online survey measuring their concerns about providing care to people living with HBV, stigmatising attitudes towards this group, perceived comfort of themselves and colleagues in providing care towards clients with HBV, and witnessing their colleagues behaviour in a discriminatory way towards clients with HBV. Multiple regression was used to ascertain factors predictive of health workers' concerns about working with clients with HBV. Results showed that older participants and those who had spent less time working in the health and medical field had greater concerns about caring for people living with HBV. Workers who did not know someone living with HBV, who were less comfortable around clients with HBV, who perceived their colleagues to be less comfortable working with clients with HBV, and who had more negative attitudes towards this group also had greater concerns around providing care to people living with HBV. Efforts should be made to improve health and medical workers' attitudes towards working with people with HBV. This may also improve workers' level of comfort with people with HBV and reduce the reported reticence they have towards working with this client group.

Cost-effectiveness of hepatitis C virus (HCV) elimination strategies among people who inject drugs (PWID) in Tijuana, Mexico

BACKGROUND AND AIMS

In Latin America, Mexico was first to launch a hepatitis C virus (HCV) elimination strategy, where people who inject drugs (PWID) are a main risk group for transmission. In Tijuana, HCV seroprevalence among PWID is > 90%, with minimal harm reduction (HR). We evaluated cost-effectiveness of strategies to achieve the incidence elimination target among PWID in Tijuana.

METHODS

Modeling study using a dynamic, cost-effectiveness model of HCV transmission and progression among active and former PWID in Tijuana, to assess the cost-effectiveness of incidence elimination strategies from a health-care provider perspective. The model incorporated PWID transitions between HR stages (no HR, only opioid agonist therapy, only high coverage needle-syringe programs, both). Four strategies that could achieve the incidence target (80% reduction by 2030) were compared with the status quo (no intervention). The strategies incorporated the number of direct-acting anti-viral (DAA) treatments required with: (1) no HR scale-up, (2) HR scale-up from 2019 to 20% coverage among PWID, (3) HR to 40% coverage and (4) HR to 50% coverage. Costs (2019 US$) and health outcomes [disability-adjusted life years (DALYs)] were discounted 3% per year. Mean incremental cost-effectiveness ratios (ICER, $/DALY averted) were compared with one-time per capita gross domestic product (GDP) ($9698 in 2019) and purchasing power parity-adjusted per capita GDP ($4842-13 557) willingness-to-pay (WTP) thresholds.

RESULTS

DAAs alone were the least costly elimination strategy [$173 million, 95% confidence interval (CI) = 126-238 million], but accrued fewer health benefits compared with strategies with HR. DAAs + 50% HR coverage among PWID averted the most DALYs but cost $265 million, 95% CI = 210-335 million). The optimal strategy was DAAs + 50% HR (ICER $6743/DALY averted compared to DAAs only) under the one-time per-capita GDP WTP ($9698).

CONCLUSIONS

A combination of high-coverage harm reduction and hepatitis C virus treatment is the optimal cost-effective strategy to achieve the HCV incidence elimination goal in Mexico.

Predictors of health care practitioners' normative attitudes and practices towards sexual and reproductive health and rights: a cross-sectional study of participants from low-income countries enrolled in a capacity-building program

Background: Sexual and Reproductive Health and Rights (SRHR) is a concept of human rights applied to sexuality and reproduction. Suboptimal access to SRHR services in many low-income countries results in poor health outcomes. Sustainable development goals (3.7 and 5.6) give a new impetus to the aspiration of universal access to high-quality SRHR services. Indispensable stakeholders in this process are healthcare practitioners who, through their actions or inactions, determine a population’s health choices. Often times, healthcare practitioners’ SRHR decisions are rooted in religious and cultural influences. We seek to understand whether religious and cultural influences differ significantly according to individuals’ characteristics and work environment.

Objective: The purpose of this study was to examine the role of healthcare practitioners’ individual characteristics and their work environment in predicting normative SRHR attitudes and behaviours (practices). We hypothesized that religion and culture could be significant predictors of SRHR attitudes and practices.

Methods: A quantitative cross-sectional study of 115 participants from ten low-income countries attending a capacity-building programme at Lund University Sweden was conducted. Linear regression models were used to assess for the predictive values of different individual characteristics and workplace environment factors for normative SRHR attitudes and SRHR practices.

Results: Self-rated SRHR knowledge was the strongest predictor for both normative SRHR attitudes and normative SRHR practices. However, when adjusted for other individual characteristics, self-rated knowledge lost its significant association with SRHR practices, instead normative SRHR attitudes and active knowledge-seeking behaviour independently predicted normative SRHR practices. Contrary to our hypothesis, importance of religion or culture in an individual’s life was not correlated with the measured SRHR attitudes and practices.

Conclusion: Healthcare practitioners’ cultural and religious beliefs, which are often depicted as barriers for implementing full coverage of SRHR services, seem to be modified by active knowledge-seeking behaviour and accumulated working experience with SRHR over time.

Is hepatitis C virus (HCV) elimination achievable among people who inject drugs in Tijuana, Mexico? A modeling analysis

BACKGROUND

In 2019, Mexico became the first Latin American country committed to hepatitis C virus (HCV) elimination, but the amount of intervention scale-up required is unclear. In Tijuana, HCV among people who inject drugs (PWID) is high; yet there is minimal and intermittent harm reduction, and involuntary exposure to compulsory abstinence programs (CAP) occurs which is associated with increased HCV risk. We determined what combination intervention scale-up can achieve HCV elimination among current and former PWID in Tijuana.

METHODS

We constructed a dynamic, deterministic model of HCV transmission, disease progression, and harm reduction among current and former PWID parameterized to Tijuana (~10,000 current PWID, 90% HCV seropositive, minimal opiate agonist therapy [OAT] or high coverage needle/syringe programs [HCNSP]). We evaluated the number of direct-acting antiviral (DAA) treatments needed from 2019 to achieve elimination targets (80% incidence reduction, 65% mortality reduction by 2030) with: (a) DAAs alone, (b) DAAs plus scale-up of OAT+HCNSP (up to 50% coverage of OAT and HCNSP separately, producing 25% of PWID receiving both), (c) DAAs plus CAP scale-up to 50%. Scenarios examined the number of DAAs required if prioritized to current PWID or provided regardless of current injection status, and impact of harm reduction interruptions.

RESULTS

Modeling suggests among ~30,000 current and former PWID in Tijuana, 16,160 (95%CI: 12,770-21,610) have chronic HCV. DAA scale-up can achieve the incidence target, requiring 770 treatments/year (95%CI: 640-970) if prioritized to current PWID. 40% fewer DAAs are required with OAT+HCNSP scale-up to 50% among PWID, whereas more are required with involuntary CAP scale-up. Both targets can only be achieved through treating both current and former PWID (1,710 treatments/year), and impact is reduced with harm reduction interruptions.

CONCLUSIONS

Elimination targets are achievable in Tijuana through scale-up of harm reduction and DAA therapy, whereas involuntary CAP and harm reduction interruptions hamper elimination.

Intoxication and overdose should not preclude veno-venous extracorporeal membrane oxygenation

Introduction

Acute intoxication (AI) related morbidity and mortality are increasing in the United States. For patients with severe respiratory failure in the setting of an acute ingestion, veno-venous extracorporeal membrane oxygenation (VV ECMO) can provide salvage therapy. The purpose of this study was to evaluate outcomes in patients with overdose-related need for VV ECMO.

Methods:

We performed a retrospective review of all patients admitted to a specialty VV ECMO unit between August 2014 and August 2018. Patients were stratified by those whose indication for VV ECMO was directly related to an acute ingestion (alcohol, illicit drug, or prescription drug overdose) and those with unrelated diagnoses. Demographics, pre-cannulation clinical characteristics, ECMO parameters, and outcomes data was collected and analyzed with parametric and non-parametric statistics as indicated.

Results:

189 patients were enrolled with 27 (14%) diagnosed with AI. Patients requiring VV ECMO for an AI were younger, had lower median BMI and PaO2/FiO2, and higher RESP scores than non-AI patients (p = 0.002, 0.01, 0.03 and 0.01). There was no difference in pre-cannulation pH, lactate, or SOFA scores between the two groups (p = 0.24, 0.5, 0.6). There was no difference in survival to discharge (p = 0.95). Among survivors, there was no difference in ECMO time or hospital stay (p = 0.24, 0.07).

Conclusion:

We demonstrate no survival difference for patients with and without an AI-related need for VV ECMO. AI patients should be supported with VV ECMO when traditional therapies fail despite potential stigma against acceptance on referral.

HIV stigma by association among Australian gay and bisexual men

OBJECTIVE

The negative effects of HIV stigma may extend beyond those who are HIV-positive, to people who are perceived to be at risk of HIV. This article examines HIV stigma by association among Australian gay and bisexual men (GBM).

DESIGN

Cross-sectional, online survey of 1280 Australian gay and bisexual men. This article focuses on HIV stigma from within a larger study that investigated stigma related to sexual identity.

METHODS

Bivariate and multivariable comparisons were made between men who experienced HIV stigma by association and those who did not. A serial mediation model was tested to investigate relationships between GBM community attachment, sexual identity stigma, HIV testing frequency, HIV stigma by association, psychological distress, and rejection of sex partners.

RESULTS

Results found that 5% of participants were HIV-positive, yet over 70% reported that they had been stigmatized by others for their perceived risk of acquiring HIV. Multivariable analysis indicated that HIV stigma by association was associated with more frequent HIV testing, greater GBM community attachment, experiencing stigma related to sexual identity and psychological distress. Our results suggest flow-on effects of HIV stigma by association, such as being more likely to reject other GBM on the basis of their HIV status or not testing for HIV.

CONCLUSION

Our results underscore the notion that HIV stigma can have broader, negative effects on HIV-affected populations. There is a need to address HIV stigma within GBM communities and society more broadly in order to encourage HIV testing and prevention among GBM.

Stigmatising attitudes towards people who inject drugs, and people living with blood borne viruses or sexually transmissible infections in a representative sample of the Australian population

Stigma has significant detrimental health outcomes for those affected. This study examined socio-demographic characteristics that were associated with stigmatising attitudes among the general population towards people who inject drugs, and people living with blood borne viruses or sexually transmissible infections. Questions were included in the Australian Survey of Social Attitudes (total sample = 1,001). Attitudes towards each of the target populations were measured by 5-item stigma scales. Bivariate analyses and multiple regression analyses were conducted to identify socio-demographic characteristics associated with stigmatising attitudes. Knowing a person affected by a stigmatised attribute was associated with reduced stigmatising attitudes, while voting for a conservative political party was associated with increased stigmatising attitudes. Age, gender, education, income, and marital status were each related to some stigmatising attitudes. Results also highlight differences between attitudes towards a stigmatised behaviour (i.e., injecting drug use) and stigmatised conditions (i.e., blood borne viruses and sexually transmissible infections). Identifying socio-demographic characteristics that are associated with stigmatising attitudes may have global implications for informing stigma reduction interventions, in order to promote positive health outcomes for affected communities.

Conceptualising access in the direct-acting antiviral era: An integrated framework to inform research and practice in HCV care for people who inject drugs

As direct-acting antiviral (DAA) therapy costs fall and eligibility criteria are relaxed, people who inject drugs (PWID) will increasingly become eligible for HCV treatment. Yet eligibility does not necessarily equate to access. Amidst efforts to expand treatment uptake in this population, we seek to synthesise and clarify the conceptual underpinnings of access to health care for PWID, with a view to informing research and practice. Integrating dominant frameworks of health service utilisation, care seeking processes, and ecological perspectives on health promotion, we present a comprehensive theoretical framework to understand, investigate and intervene upon barriers and facilitators to HCV care for PWID. Built upon the concept of Candidacy, the framework describes access to care as a continually negotiated product of the alignment between individuals, health professionals, and health systems. Individuals must identify themselves as candidates for services and then work to stake this claim; health professionals serve as gatekeepers, adjudicating asserted candidacies within the context of localised operating conditions; and repeated interactions build experiential knowledge and patient-practitioner relationships, influencing identification and assertion of candidacy over time. These processes occur within a complex social ecology of interdependent individual, service, system, and policy factors, on which other established theories provide guidance. There is a pressing need for a deliberate and nuanced theory of health care access to complement efforts to document the HCV 'cascade of care' among PWID. We offer this framework as an organising device for observational research, intervention, and implementation science to expand access to HCV care in this vulnerable population. Using practical examples from the HCV literature, we demonstrate its utility for specifying research questions and intervention targets across multiple levels of influence; describing and testing plausible effect mechanisms; and identifying potential threats to validity or barriers to research translation.
