"It Ruined My Life": The effects of the War on Drugs on people who inject drugs (PWID) in rural Puerto Rico

"It didn't hurt me": patients' and providers' perspectives on unsupervised take-home doses, drug diversion, and overdose risks in the provision of medication for opioid use disorder during COVID-19 in San Juan, Puerto Rico

BACKGROUND

During the COVID-19 pandemic, clinics offering medication for opioid use disorder (MOUD) needed to rapidly introduce unsupervised take-home dosing, while relapsing patients and patients unable to enter treatment faced increased risks of fentanyl-related overdose deaths and other drug-related harms. Based on a qualitative study of people who inject drugs (PWID) receiving MOUD treatment and MOUD staff in Puerto Rico, this paper documents the lived experiences of patients and providers during this period and the risk perceptions and management strategies to address substance misuse and drug diversion attributable to unsupervised take-home-dose delivery.

METHODS

In-depth qualitative interviews were conducted with patients (N = 25) and staff (N = 25) in two clinics providing MOUD in San Juan, Puerto Rico, during 2022. Patients and staff were receiving or providing treatment during the pandemic, and patients reported injection drug use during the past thirty days.

RESULTS

Patients were overwhelmingly male (84%), unmarried (72%), and unemployed (52%), with almost half (44%) injecting one to three times a day. Mean time in treatment was 7 years. Staff had a mean age of 46 years with more than half of the sample (63%) female. The majority of patients believed that unsupervised take-home dosing had no significant effect on their treatment adherence or engagement. In contrast, providers expressed concerns over the potential for drug diversion and possible increased risks of patient attrition, overdose episodes, and poor treatment outcomes.

CONCLUSION

This study underscores the importance of insider perspectives on harm-reduction changes in policy implemented during a health crisis. Of note is the finding that staff disagreed among themselves regarding the potential harms of diversion and changes in drug testing protocols. These different perspectives are important to address so that future pandemic policies are successfully designed and implemented. Our study also illuminates disagreement in risk assessments between patients and providers. This suggests that preparation for emergency treatment plans requires enhanced communication with patients to match treatments to the context of lived experience.

"I don't want to die": a qualitative study of coping strategies to prevent fentanyl-related overdose deaths among people who inject drugs and its implications for harm reduction policies

BACKGROUND

Fentanyl and fentanyl-related analogues are the main drivers of overdose death in the USA, particularly among people who inject drugs (PWID). Despite the fact that non-Hispanic whites exhibit higher population rates of synthetic opioid mortality, overdose deaths have increased among African American and Latinos in urban areas. Yet little attention has been paid to the introduction of fentanyl among rural PWID in Puerto Rico.

METHODS

We conducted N = 38 in-depth interviews with PWID in rural Puerto Rico to document participants' experiences of injection drug use after the arrival of fentanyl and the strategies they implemented to manage overdose death risks.

RESULTS

Participants suggest that the arrival of fentanyl in large scale happened after Hurricane Maria in 2017; this coincided with a dramatic increase in overdose episodes and deaths. Fear of overdose deaths motivated some participants to substitute intravenous drug use for other forms of substance use or to seek MOUD. PWID that continued injection use resorted to conducting "hit tests," avoiding injecting alone, using naloxone, and employing fentanyl testing strips.

CONCLUSIONS

While overdose deaths would have been higher without participants' willingness to adopt harm-reduction strategies, this paper illustrates the limits of these policies to address the current epidemic of fentanyl-related overdose deaths among this population. More studies are needed to understand how health disparities shape overdose risks for minority populations. However, major policy changes, in particular the revision of the harmful role of the War on Drugs and the termination of failed neoliberal economic policies that contribute to deaths of despair, should be addressed if we are to make a dent in this epidemic.

"The Drug Sellers Were Better Organized than the Government": A Qualitative Study of Participants' Views of Drug Markets during COVID-19 and Other Big Events

"Big events", such as wars, economic crises, pandemics, or natural disasters, affect the risk environment in which people use drugs. While the impact of big events on injection risk behaviors and access to drug-treatment services is well documented, less is known about the effects of big events on drug markets. Based on self-reporting data on drug availability among people who use drugs (PWUD) in the aftermath of Hurricane Maria in Puerto Rico and during the COVID-19 lockdown in a Midwestern US state, this study aims to document the effects of big events on drug markets. Qualitative data on the effects of Hurricane Maria on drug markets are based on participants' self-reporting (N = 31). Data collection started after the hurricane and ended in 2020. Data on changes to the drug supply during the COVID-19 lockdown were collected based on semi-structured interviews with PWUD (N = 40) in a Midwestern US state. Findings show that while the drug markets might have initially been affected by big events, most effects were temporary. Drug availability, pricing, and quality might have suffered some initial fluctuations but stabilized as the drug markets absorbed the initial shocks caused by the hurricane and the lockdown measures. In preparation for increasingly more frequent and virulent pandemics and natural disasters, health infrastructures should be strengthened to prevent not only overdose episodes and deaths but also drug-related harms.

Substance use, injection risk behaviors, and fentanyl-related overdose risk among a sample of PWID post-Hurricane Maria

BACKGROUND

While natural disasters like hurricanes are increasingly common, their long-term effects on people who inject drugs are not well understood. Although brief in duration, natural disasters can radically transform risk environments, increasing substance use and drug-related harms.

METHODS

Based on a study of people who inject drugs (PWID) and injection risk behaviors in rural Puerto Rico, the present study uses data from two different phases of the parent study. Data for 110 participants were collected from December 2015 to January 2017, soon before Hurricane Maria landed in September 2017; the 2019 phase, in the aftermath of the hurricane, included a total of 103 participants. The present study's main analyses used data from 66 PWID who participated in both the pre-Maria and post-Maria interviews (66 individuals measured at two time points, for a total of 132 observations), using mixed-effects binomial logistic regression to examine recent overdose experiences pre- and post-Maria. A separate descriptive analysis included all 103 participants from the 2019 interview.

RESULTS

After Hurricane Maria, some declines in injection frequency were observed (the percentage of people reporting injecting monthly or less increased from 3.0% before Hurricane Maria to 22.7% after Hurricane Maria). However, fewer PWID reported using a new needle for most or all injections. In the pre-Maria interview, 10.6% of participants indicated they had experienced an overdose during the year of the interview and/or the calendar year prior, and this figure increased to 24.2% in the post-Maria interview. In the regression analysis, the odds of reporting an overdose during the interview year and/or calendar year prior were three times as high post-Maria, relative to pre-Maria (odds ratio 3.25, 95% confidence interval 1.06-9.97).

CONCLUSION

Substance use patterns, injection risk behaviors, and overdose episodes and deaths differed after Hurricane Maria, relative to before the hurricane, yet it is unclear to what extent these changes also reflect the simultaneous arrival of fentanyl. In preparation for future natural disasters, it is imperative to strengthen the health infrastructure by enhancing access and curbing barriers to syringe services programs and medications for opioid use disorder, particularly in rural or underserved locations.

Unintended harm: A qualitative study of "harm" upon people who inject drugs in Bangkok, Thailand

Given the highly pervasive health threats faced by people who inject drugs, harm reduction has been implemented in Thailand. Although harm reduction is a particularly effective public health strategy for reducing risky behavior, it is currently practiced with minimal understanding of unintended harm-drug policy, social exclusion, stigma, and discrimination-for people who inject drugs (PWID) in Thailand. This study aims to understanding the "unintended harm" encountered by people who inject drugs in Bangkok in their everyday lives through social interaction at all levels of society from macro, micro, and individual levels. In-depth interviews were conducted with 28 people who inject drugs in Bangkok (21 men and 7 women) and 4 people who are a nurse, a community leader, a policeman, and a family member (2 men and 2 women). The result shows that individuals, society, and politics are not separable phenomena and all produce harm upon people who inject drugs. These unintended harms on the macro, micro, and individual level are closely linked; each in their own way poses a threat to the health and well-being of people who inject drugs and embody negative social responses as the people who inject drugs become typecast as "deviants." In conclusion, there is an urgent need to develop a "harm reduction" model that addresses unintended harm and could be integrated within the existing socio-cultural context of Thai society.

"I held on to the police's leg for mercy": Experiences of adversity, risk and harm among people who inject drugs during an anti-drug drive in Dhaka, Bangladesh

BACKGROUND

A number of countries across Asia have instituted "drug wars", aimed at eradicating drug supply and consumption. These wars often employ strategies like arbitrary arrest and detention, increased surveillance, harassment and sometimes extrajudicial killings. However, these measures have not been shown to effectively eliminate drug supply and consumption; rather they often predispose people who use drugs to increased risk and harm. Such a drug war was declared in the form of an anti-drug drive (ADD) in Bangladesh in 2018. This article examined the impact of the ADD on drug injecting activities and harm reduction service uptake among people who inject drugs (PWID).

METHODS

An ethnographic study was conducted in Dhaka, Bangladesh. Study participants included PWID, harm reduction service providers and other drug and alcohol experts. Data collection consisted of 2500 hours of observations, 25 in-depth interviews, five focus group discussions and 15 key informant interviews. Data were analysed using thematic analysis.

RESULTS

ADD operations and activities subjected PWID to multifaceted forms of violence and harassment including extrajudicial killings, which significantly affected drug procurement and drug using practices and led to increased needle and syringe sharing and a likely increase in HIV transmission. The gradual disappearance of established drug markets, alongside the emergence of new ones at alternate locations, resulted in the dislocation of PWID from outreach services and further increased risky injecting practices such as needle and syringe sharing between new and unfamiliar injecting partners. These harms were compounded by unpredictable drug supply and price increases stemming from the ADD, which in turn also increased needle and syringe sharing. Harm reduction outreach services were not able to adequately adapt to the volatile, dynamic and risky nature of the ADD.

CONCLUSION

The ADD not only precipitated risky injecting practices but also hindered the effective implementation of harm reduction outreach services and thus undermined public health. This warrants concerted efforts to nurture local evidence-based harm reduction approaches as opposed to punitive measures.

The wound that closes doors: Lived experiences and complexities of injection-related injuries and infections among people who inject drugs through an ethnographic lens

BACKGROUND

Besides HIV, people who inject drugs (PWID) experience other biomedical adversities, including injection-related injuries and infections. Yet, they are often inadequately addressed due to the prioritisation of HIV-related issues. This article explored the risk environment and socio-structural adversities of PWID living with injection-related injuries and infections, as well as existing management and treatment challenges of these conditions in harm reduction interventions.

METHODS

We undertook an ethnographic study from April 2018 to December 2019 in selected areas of Dhaka, Bangladesh. This component of the study involved 2500 hours of observations and informal conversations, 35 in-depth interviews and five focus group discussions with PWID experiencing injection-related injuries and infections. We also performed seven key-informant interviews with service providers and clinical experts. We applied thematic analysis and used various theoretical social scientific conceptualisations to analyse the relationship between the biomedical realities and socio-structural vulnerabilities of PWID.

RESULTS

Our findings indicated that PWID's physical, legal and socio-economic environments predisposed PWID to risky practices which ultimately precipitated injection-related injuries and infections. These injection-related injuries and infections consequently displaced them in spheres of social exclusion, stigmatisation, physical pain and disability and, hence, fueled their feelings of distress and despondence. Our findings also presented limitations in the management strategy of these injection-related injuries and infections. Specifically, service providers misconstrued all these complexities as "abscesses", thus applying a simplistic "one-size-fits-all" approach without accounting for the diversity of these complexities. This led to a paucity of tailored care and management approaches which could precipitate unfavourable treatment outcomes, such as chronic and complicated cases with antibiotic resistance.

CONCLUSION

Injection-related injuries and infections nestled PWID within various prongs of biomedical and socio-structural adversity, without viable and targeted treatment modalities. Thus, it is integral to nurture a multifaceted harm reduction intervention tailored to their biomedical and socio-structural needs.

Drug overdose mortality among stateside Puerto Ricans: Evidence of a health disparity

BACKGROUND

This study compared drug overdose mortality rates in Puerto Rican-heritage and Non-Hispanic (NH) White individuals in the United States (US), examining time trends and recent variation by age, sex, state of residence, and drugs involved in overdose.

METHODS

Death certificate data from the National Center for Health Statistics, as well as American Community Survey population estimates, were used to calculate age-specific and age-adjusted drug overdose mortality rates for Puerto Rican-heritage and NH White residents of the 50 United States or District of Columbia (DC). Rates for 2018 were compared between Puerto Rican-heritage and NH White individuals, overall and by sex, age, state, and specific drug involved in overdose. Joinpoint Regression was used to examine trends in drug overdose mortality rates from 2009 to 2018.

RESULTS

From 2009 to 2018, the age-adjusted drug overdose mortality rate in stateside Puerto Ricans doubled among women (from 6.0 to 12.5 per 100,000) and nearly tripled among men (from 15.3 to 45.2 per 100,000). In 2018, the age-adjusted drug overdose mortality rate was significantly higher in Puerto Rican-heritage than NH White individuals (28.7 vs. 26.2 per 100,000, respectively). The 2018 drug overdose mortality rate was highest among Puerto Rican-heritage men ages 45-54 (104.1 per 100,000).

CONCLUSION

Findings emphasize the necessity of policies, programs, and interventions to mitigate risk of fatal overdose in stateside Puerto Rican communities.

"Caballo": risk environments, drug sharing and the emergence of a hepatitis C virus epidemic among people who inject drugs in Puerto Rico

BACKGROUND

Sharing drug injection equipment has been associated with the transmission of HCV among PWID through blood contained in the cooker and cotton used to prepare and divide up the drug solution. While epidemiologists often subsume this practice under the sharing of "ancillary equipment," more attention should be paid to the fact that indirect sharing takes place within the process of joint drug acquisition and preparation.

METHODS

We employed an ethnographic approach observing active PWID (N = 33) in four rural towns in Puerto Rico in order to document drug sharing arrangements involved in "caballo", as this practice is locally known. We explored partners' motivation to engage in drug sharing, as well as its social organization, social roles and existing norms.

FINDINGS

Findings suggest that drug sharing, is one of the main drivers of the HCV epidemic in this population. Lack of financial resources, drug packaging, drug of choice and the desire to avoid the painful effects of heroin withdrawal motivates participants' decision to partner with somebody else, sharing injection equipment-and risk-in the process. Roles are not fixed, changing not only according to caballo partners, but also, power dynamics.

CONCLUSION

In order to curb the HCV epidemic, harm reduction policies should recognize the particular sociocultural contexts in which people inject drugs and make decisions about risk. Avoiding sharing of injection equipment within an arrangement between PWID to acquire and use drugs is more complex than assumed by harm reduction interventions. Moving beyond individual risk behaviors, a risk environment approach suggest that poverty, and a strict drug policy that encourage users to carry small amounts of illicit substances, and a lack of HCV treatment among other factors, contribute to HCV transmission.

Hepatitis C treatment uptake among people who inject drugs in the oral direct-acting antiviral era

BACKGROUND

Increased uptake of hepatitis C virus (HCV) treatment among people who inject drugs (PWID) will be critical to achieve HCV elimination goals. There are limited data on HCV treatment uptake among PWID recruited from community-based settings in the HCV direct-acting antiviral (DAA) era.

METHODS

We analysed data from PWID with HCV newly recruited into the Baltimore, Maryland-based AIDS Linked to the IntraVenous Experience (ALIVE) cohort between 2015 and 2018. We characterized the HCV care continuum and evaluated factors associated with HCV treatment uptake.

RESULTS

Of the 418 PWID with HCV, the median age was 49 years and most (88%) reported recent injection drug use (IDU). Overall, 23% had ever been evaluated by a provider for HCV treatment, 17% ever initiated DAA treatment and 13% were cured of HCV infection. Treatment uptake approximately doubled between 2015 and 2018 (13% to 26%, P = .01). In multivariable analyses, HIV infection (adjusted Odds Ratio [aOR] 2.5 [95% Confidence Interval (CI) 1.3, 4.8]), current employment (aOR 4.1 [CI 1.2, 14.4]), having a primary care provider (aOR 4.3 [CI 1.2, 14.9) and longer duration of IDU (aOR 1.3 [CI 1.1, 1.6]) were positively associated with HCV treatment. PWID with a lower annual income (≤$5000) were less likely to have initiated HCV treatment (aOR 0.5 [CI 0.3, 0.98]).

CONCLUSIONS

Although HCV treatment uptake among PWID in this community-based setting in the DAA era remains suboptimal, it is encouraging that treatment uptake has increased in recent years. Innovative strategies are needed to reach all PWID infected with HCV.

Competing forces of withdrawal and disease avoidance in the risk networks of people who inject drugs

We analyze a network of needle-sharing ties among 117 people who inject drugs (PWID) in rural Puerto Rico, using exponential random graph modeling to examine whether network members engage in partner restriction to lower their risk of contracting HIV or hepatitis C (HCV), or in informed altruism to prevent others from contracting these infections. Although sharing of used syringes is a significant risk factor for transmission of these diseases among PWID, we find limited evidence for partner restriction or informed altruism in the network of reported needle-sharing ties. We find however that sharing of needles is strongly reciprocal, and individuals with higher injection frequency are more likely to have injected with a used needle. Drawing on our ethnographic work, we discuss how the network structures we observe may relate to a decision-making rationale focused on avoiding withdrawal sickness, which leads to risk-taking behaviors in this poor, rural context where economic considerations often lead PWID to cooperate in the acquisition and use of drugs.

The impact of rurality on opioid-related harms: A systematic review of qualitative research

INTRODUCTION

Over the past decade, there has been mounting recognition that opioid use and related mortality and morbidity is a significant public health problem in rural, non-urban areas across the globe. Taking what has been termed the 'opioid crisis' as a starting off point, this article aims to systematically review the qualitative literature on the ways in which rurality shapes the risk for opioid-related harm.

METHODS

A systematic review was undertaken using database searches and secondary reference list searches for qualitative literature on rural and non-urban opioid-related harms. A total of 32 qualitative studies met the inclusion criteria. Data extraction was performed in NVivo 12 using a codebook based on the 'risk environment' framework.

RESULTS

The findings explore how rurality shapes the risk environment for opioid-related harms through four environment influences: (1) economic conditions, including economic transition and deindustrialisation that has occurred in many rural areas, and the high levels of economic distress experienced by rural residents; (2) physical conditions, including a lack of infrastructure and recreation opportunities, larger geographic distances, and limited transportation; (3) social conditions, where social networks could be both protective but also amplify risk through a lack of knowledge about treatment and risk behaviours, a lack of anonymity and stigmatisation of people who use opioids in rural areas; and (4) policy conditions including limited coverage and availability of harm reduction and drug treatment services, and stigmatising service provider practices.

CONCLUSIONS

The impact of rurality on risk of opioid-related harm is multifaceted. We suggest that future research on rural opioid use would benefit from drawing on the theoretical toolkit of rural criminology to attend to the ways the 'rural crisis', and attendant insecurities, anxieties and strains, impacts upon rural communities and shapes risk, along with how socio-cultural characteristics of the rural 'organise' risks of drug use.

People, places, and stigma: A qualitative study exploring the overdose risk environment in rural Kentucky

BACKGROUND

Though overdose rates have been increasing in US rural areas for two decades, little is known about the rural risk environment for overdoses. This qualitative study explored the risk environment for overdoses among young adults in Eastern Kentucky, a rural epicenter of the US opioid epidemic.

METHODS

Participants were recruited via community-based outreach. Eligibility criteria included living in one of five rural Eastern Kentucky counties; being aged 18-35; and using opioids to get high in the past 30 days. Semi-structured interviews explored the rural risk environment, and strategies to prevent overdose and dying from an overdose. Interviews were transcribed verbatim and analyzed using constructivist grounded-theory methods.

RESULTS

In this sample (N = 19), participants reported using in a range of locations, including homes and outdoor settings; concerns about community stigma and law enforcement shaped the settings where participants used opioids and the strategies they deployed in these settings to prevent an overdose, and to survive an overdose. Almost half of participants reported using opioids in a "trap house" or other dealing locations, often to evade police after buying drugs, and reported that others present pressed them to use more than usual. If an overdose occurred in this setting, however, these same people might refuse to call EMS to protect themselves from arrest. Outdoor settings presented particular vulnerabilities to overdose and dying from an overdose. Most participants reported using opioids outdoors, where they skipped overdose prevention steps to reduce their risk of arrest; they worried that no one would find them if they overdosed, and that cell phone coverage would be too weak to summon EMS.

CONCLUSION

Findings suggest that initiatives to reduce overdoses in Eastern Kentucky would be strengthened by de-escalating the War on Drugs and engaging law enforcement in initiatives to protect the health of people who use opioids.

Injection risk norms and practices among migrant Puerto Rican people who inject drugs in New York City: The limits of acculturation theory

BACKGROUND

Among people who inject drugs (PWID) in New York City (NYC), racial minorities are disproportionately infected with HIV and hepatitis C (HCV). Prior research has shown that PWID who started injecting drugs in Puerto Rico (P.R.) tend to maintain the risky injection behaviors learned there. This study identifies the P.R.-native norms supporting the continued injection risk behavior of migrant Puerto Rican PWID in NYC to inform a culturally appropriate risk-reduction intervention.

METHODS

40 migrant Puerto Rican PWID were recruited in NYC for a longitudinal qualitative study. The sample was stratified to include 20 migrants with <3 years in NYC and 20 migrants with >3-6 years in NYC. Time-location sampling was used to curb possible network bias in recruitment. Over 12 months, migrants completed semi-structured interviews at baseline, monthly follow-ups, and study exit. Analyses were guided by grounded theory.

RESULTS

Most participants (90%) reported having had chronic HCV, and 22.5% reported being HIV-positive. Syringe- and cooker-/cotton-sharing were widespread in both P.R. and NYC. The ubiquitous practice of cleaning used syringes by "water-rinsing and air-blowing" was guided by a normative belief, learned in P.R., that "water and air kill HIV." Sterile syringe use was not a priority. HCV was not a concern. P.R.-native abstinence-only narratives discouraged opioid agonist treatment (OAT) enrollment among recent migrants (≤3 years). Experiences with drug dealers, prison-power groups, and injection doctors ("Gancheros") in P.R. influenced migrants' injection risk behavior in NYC. Those who were Gancheros in P.R. continued working as Gancheros in NYC.

CONCLUSIONS

Injection risks make migrant Puerto Rican PWID in NYC vulnerable to HIV/HCV. Harm reduction programs should pay closer attention to the rationales behind these injection risks. A risk-reduction intervention that incorporates the Ganchero figure may be a credible way to help migrants reduce injection risk and accept OAT and syringe exchange programs (SEP).

World Opioid and Substance Use Epidemic: A Latin American Perspective

The opioid crisis is a growing social and public health phenomenon, particularly in developed countries such as the United States. Since the 1990s, this crisis has shown a variety of causal processes and consequences and has affected quality of life for millions of individuals, families, and communities across the globe. Although abuse of opioid‐based painkillers appears to have triggered the epidemic in the United States, in this article, the problem is examined with a focus on Latin America, where drug‐associated problems constitute threats to the health and quality of life for large segments of the population. After a review of the history of opium consumption and its consequences in the world and in Latin America, the authors present epidemiological data and information about regional market differences, professional involvement, clinical practices, public health realities, and prevention efforts. Recommendations are made for collaborative efforts to promote prevention policies and measures to improve the situation.

Establishing trust in HIV/HCV research among people who inject drugs (PWID): Insights from empirical research

BACKGROUND

The establishment of trust between researchers and participants is critical to advance HIV and HCV prevention particularly among people who inject drugs (PWID) and other marginalized populations, yet empirical research on how to establish and maintain trust in the course of community health research is lacking. This paper documents ideas about trust between research participants and researchers amongst a sub-sample of PWID who were enrolled in a large, multi-year community health study of social networks and HIV/HCV risk that was recently conducted in rural Puerto Rico.

METHODS

Qualitative research was nested within a multi-year Social Network and HIV/HCV Risk study involving N = 360 PWID > 18 years of age living in four small, rural Puerto Rican communities. Semi-structured interviews were conducted between March 2017 and April 2017 with a subset of 40 active PWID who had been enrolled in the parent study. Interview questions invited participants to draw upon their recent experience as research participants to better understand how PWID perceive and understand participant-researcher trust within the context of HIV/HCV-related epidemiological research.

RESULTS

Fear of police, stigma and concerns regarding confidentiality and anonymity were identified as structural factors that could compromise participation in HIV/HCV-related research for PWID. While monetary compensation was an important motivation, participants also valued the opportunity to learn about their HIV/HCV status. During their participation in the study, gaining knowledge of safe injection practices was perceived as a valuable benefit. Participant narratives suggested that PWID may adopt an incremental and ongoing approach in their assessment of the trustworthiness of researchers, continuously assessing the extent to which they trust the research staff throughout the course of the research. Trust was initially generated through peer Respondent Driven Sampling recruitment. Research staff who maintained a presence in the community for the entire duration of the prospective study reinforced trust between participants and the research team.

CONCLUSION

Although PWID face numerous structural barriers to research-related trust in HIV/HCV research, we found that using a peer-based recruitment method like RDS, and employing a research staff who are knowledgeable about the targeted population, culturally sensitive to their needs, and who maintain a long-term presence in the community may help mitigate many of these barriers. The reputation of the research is built incrementally as participants join the study. This contributes to a "street reputation" that grows as current or former participants vouch for the study. Establishing trust was identified as only the first step towards building a collaborative relationship with participants, and our findings suggest that steps to address criminalization and stigmatization also are necessary to support research trust.
