The interplay between drug-use behaviors, settings, and access to care: a qualitative study exploring attitudes and experiences of crack cocaine users in Rio de Janeiro and São Paulo, Brazil

Breaking barriers: a qualitative exploration of healthcare access for crack cocaine users in Limerick

BACKGROUND OF STUDY

Crack cocaine use in Ireland began to emerge as a significant problem in the early 2000s, with prevalence increasing from 2016 onwards. Services such as harm reduction, treatment/rehabilitation, primary healthcare and social services are available to crack cocaine users in Ireland. However, research addressing specific barriers to accessing these services remains limited. Internationally, while research on healthcare access barriers for crack cocaine users exists, it predominantly focuses on user perspectives. This paper uses a dual-perspective approach to investigate access challenges from both service user and service provider viewpoints, promoting a more patient-centred, holistic approach to service provision.

METHODOLOGY

The study is qualitative and used semi-structured interviews and a focus group to obtain study data. Levesque's conceptual framework for healthcare access underpins this study. Data were analysed using thematic analysis.

RESULTS

The study highlighted barriers to healthcare access such as the inadequacy of services to support those with dual diagnosis. However, an advancement has been made through the establishment of specialised dual diagnosis teams and community dual diagnosis services in Ireland. Stigma from health care providers further hindered people from seeking help, highlighting the significance of ongoing efforts in Ireland to address stigma. Systemic factors such as distrust in services, stringent requirements and insufficient knowledge of user needs hamper timely access to care, underlining the need for more adaptive responses.

CONCLUSION

The study underlines the need for a tailored approach to enhancing access to health care for crack cocaine users in Ireland. Facilitating collaboration among health care providers, fostering partnerships with educational institutions/communities, and implementing policy changes are essential in creating a supportive environment that promotes help-seeking in Ireland.

The joy and pain of being a harm reduction worker: a qualitative study of the meanings about harm reduction in Brazil

BACKGROUND

Although harm reduction is highlighted as an effective intervention for alcohol and drug use, a funding gap for harm reduction interventions has been identified, mainly in low- and middle-income countries. In these countries, tensions between abstinence and harm reduction models have impaired the shift from punitive practices to evidence-based interventions committed to guaranteeing the human rights of people who use drugs. Since 2015, the Brazilian government has adopted a more punitive and abstinence-focused drug policy that jeopardizes the care of people who use alcohol and other drugs and the comprehension of the harm reduction workers' perspective in relation to their practice. Therefore, this study aimed to comprehend the meanings constructed by Brazilian harm reduction workers regarding their practices with vulnerable populations amidst a context of political tension.

METHODS

We conducted 15 in-depth semi-structured qualitative interviews with harm reduction workers employed in public health services for at least 6 months. Data were analyzed using thematic analysis.

RESULTS

The thematic axis "The joy and pain of being a harm reduction worker in Brazil" was constructed and divided into four major themes: (1) Invisibility of harm reduction work; (2) Black, poor, and people who use drugs: identification with the service users; (3) Between advocacy and profession: harm reduction as a political act; (4) Small achievements matter. Despite the perceived invisibility of harm reduction workers in the public health and alcohol and drug fields, valuing small achievements and advocacy were important resources to deal with political tension and punitive strategies in Brazil. The findings also highlight the important role of harm reduction workers due to their personal characteristics and understanding of drug use behavior, which bring the target audience closer to actions within the public health system.

CONCLUSION

There is an urgent need to acknowledge harm reduction based on peer support as a professional category that deserves adequate financial support and workplace benefits. Additionally, expanding evidence-based harm reduction interventions and community-based voluntary drug use treatment centers should be prioritized by public policies to address the human rights violations experienced by people who use drugs.

Syphilis and Co-Infections with HIV-1, HBV, and HCV among People Who Use Crack-Cocaine in Northern Brazil

The rates of syphilis and viral co-infections among people who use crack-cocaine (PWUCC) were assessed in this study. This cross-sectional study relied on biological and self-reported socio-behavioral data from a convenience sample of 990 PWUCC from twenty-six municipalities in the states of Amapá and Pará, northern Brazil. Blood samples were collected to assess the presence of Treponema pallidum using the Rapid Qualitative Test (RQT) and the Venereal Disease Research Laboratory (VDRL). Reactive samples by RQT were used to assess the presence of HBV, HCV, and HIV-1 using Enzyme Immunoassay (EIA) and Polymerase Chain Reaction (PCR). Logistic regression models were used to determine the association of variables assessed with syphilis. In total, 287 (29.0%) of the PWUCC sample had reactive results for syphilis. HBV (15.7%), HCV (5.9%), and HIV-1 (9.8%) were detected among PWUCC with syphilis. Young age, low monthly income and education level, long duration of crack-cocaine use, condomless sex, multiple sex partners, and exchange of sex for money/drugs were associated with syphilis. The present study provides unique insights on the epidemiological status of syphilis among PWUCC in northern Brazil, with multiple implications for improving urgent interventions for diagnosis, prevention, and treatment.

The Perceptions of Domestic Violence by a Family Member Who Uses Crack or Cocaine: A Secondary Retrospective Cross-Sectional Study

OBJECTIVE

To evaluate the relationship between crack/cocaine use and domestic violence perpetration from the perspective of substance users' families. A secondary retrospective cross-sectional study, with 3162 family members of crack/cocaine users seeking treatment in the Recomeço Família Programme in São Paulo/Brazil was undertaken. Family members of crack/cocaine users reported that their relatives were more involved in domestic violence such as stealing (money and objects) at home [Odds Ratio Adjusted ORA = 2.17 (CI 95% 1.87; 2.53)], the family gave money to the user to buy drugs [ORA = 1.27 (1.08; 1.48)], and having problems with the judiciary [ORA = 1.48 (CI 95% 1.28; 1.71)]. Relatives of snorted cocaine users reported that there was physical and interpersonal violence, such as fathers being assaulted [ORA = 2.50 (CI 95% 1.08; 5.82)], assaulted someone else [ORA = 1.86 (CI 95% 1.32; 2.60)], threats of violence fights, arguments when the family talk about problematic drug use [ORA = 1.50 (CI 95% 1.13; 1.96)] and threatened some family members [ORA = 1.52 (CI 95% 1.14; 2.04)]. In this sample, there was a connection between crack/cocaine use and the perpetuation of domestic violence, corroborating with important implications for public policies, substance use treatment and prevention of domestic violence interventions.

Examining a migration-based phenomenon of heroin use in an urban drug scene in Sao Paulo, Brazil

Purpose

Brazil’s street-based drug use is mostly characterized by non-injection psychostimulant (e.g. crack-cocaine) drug use in Brazil, with limited interventions and service availability. Recently, an influx of multi-ethnic migrants within an urban drug scene in Sao Paulo was associated with heroin use, a drug normatively absent from Brazil. The purpose of this paper is to characterize and compare heroin use-related characteristics and outcomes for an attending sub-sample of clients from a large community-based treatment centre (“CRATOD”) serving Sao Paulo’s local urban drug scene.

Design/methodology/approach

All non-Brazilian patients (n = 109) receiving services at CRATOD for 2013–2016 were identified from patient files, divided into heroin users (n = 40) and non-heroin users (n = 69). Based on chart reviews, select socio-demographic, drug use and health status (including blood-borne-virus and other infections per rapid test methods) were examined and bi-variately compared. Multi-variate analyses examined factors independently associated with heroin use.

Findings

Most participants were male and middle-aged, poly-drug users and socio-economically marginalized. While heroin users primarily originated from Africa, they reported significantly more criminal histories, drug (e.g. injection) and sex-risk behaviors and elevated rates of BBV (e.g. Hepatitis C Virus and HIV). A minority of heroin users attending the clinic was provided methadone treatment, mostly for detoxification.

Originality/value

This study documented information on a distinct sample of mostly migration-based heroin users in Sao Paulo, Brazil. Based on the local experience, global migration dynamics can bring changes to established drug use cultures and services, including new challenges for drug use-related related behaviors and therapeutic interventions that require effective understanding and addressing.

Oral HPV among people who use crack-cocaine: prevalence, genotypes, risk factors, and key interventions in a remote Northern Brazilian region

OBJECTIVES

This study estimated the prevalence, genotype distribution, and the factors associated with oral human papillomavirus (HPV) in people who use crack-cocaine (PWUCC) in a remote Brazilian region.

MATERIALS AND METHODS

This cross-sectional study used community-based snowball sampling methods for participant recruitment. Socio-demographic, economic, drug use, and health-related information was collected from 278 PWUCC in the cities of Bragança and Capanema in northern Brazil. HPV diagnosis and genotyping were performed by a real-time polymerase chain reaction. Logistic regression identified the factors independently associated with oral HPV.

RESULTS

In total, 111 (39.9%) PWUCC had HPV DNA. Several genotypes were identified, some of them with high oncogenic potential. Crack-cocaine use ≥40 months, unprotected sex, more than 10 sexual partners in the last 12 months, oral sex, exchange of sex for money or illicit drugs, oral mucosa lesions, not having access to public health services, and the absence of vaccination against HPV was all associated with HPV DNA.

CONCLUSIONS

This study identified important epidemiological characteristics of oral HPV infection among PWUCC-a highly marginalized risk population-underlining the high prevalence of oral HPV with oncogenic potential and the urgent need for control and prevention measures, especially vaccination against this virus.

CLINICAL RELEVANCE

It is necessary to understand the prevalence and risk factors of oral HPV in risk populations as people who use crack-cocaine.

A scoping review of health-related stigma outcomes for high-burden diseases in low- and middle-income countries

BACKGROUND

Stigma is associated with health conditions that drive disease burden in low- and middle-income countries (LMICs), including HIV, tuberculosis, mental health problems, epilepsy, and substance use disorders. However, the literature discussing the relationship between stigma and health outcomes is largely fragmented within disease-specific siloes, thus limiting the identification of common moderators or mechanisms through which stigma potentiates adverse health outcomes as well as the development of broadly relevant stigma mitigation interventions.

METHODS

We conducted a scoping review to provide a critical overview of the breadth of research on stigma for each of the five aforementioned conditions in LMICs, including their methodological strengths and limitations.

RESULTS

Across the range of diseases and disorders studied, stigma is associated with poor health outcomes, including help- and treatment-seeking behaviors. Common methodological limitations include a lack of prospective studies, non-representative samples resulting in limited generalizability, and a dearth of data on mediators and moderators of the relationship between stigma and health outcomes.

CONCLUSIONS

Implementing effective stigma mitigation interventions at scale necessitates transdisciplinary longitudinal studies that examine how stigma potentiates the risk for adverse outcomes for high-burden health conditions in community-based samples in LMICs.

Predictive factors associated with driving under the influence among Brazilian drug-using drivers

The incidence of driving under the influence of psychoactive substances (DUI) and its recidivism can be curtailed by the proper identification of specific and predictive characteristics among drug users. In this sense, interpersonal violence (IV), psychiatric comorbidity and impulsivity seem to play an important role in DUI engagement according to previous studies. There are, however, limited data originated from low and middle income countries. In the present study, drug-using Brazilian drivers reporting DUI (n = 75) presented a higher prevalence of bipolar disorders (BD; DUI: 8% vs. non-DUI: 0%, p < 0.001), lower prevalence of obsessive-compulsive disorder (OCD; DUI: 0% vs. non-DUI: 12.6%, p < 0.001), and higher prevalence of childhood trauma (DUI: 65.3% vs. non-DUI: 46.8%, p = 0.022) than those not reporting DUI (n = 79). The evaluation of impulsivity though the Barratt Impulsivity Scale, which give impulsivity scores ranging from 30 to 120, showed higher impulsivity scores in the DUI group (80.4 ± 8) than in the non-DUI group (77.2 ± 10, p = 0.045). In general, subjects were young adults (mean age of 36 ± 9 years), Caucasians (58.4%), not married (61.0%), and with elementary schooling (40.3%) with no significant differences in demographic characteristics between drivers with and without DUI behavior. A multiple Poisson regression model showed that individuals reporting IV as perpetrators and history of childhood trauma were more likely to report DUI (PR: 1.66, 95%CI 1.22-2.7; PR: 1.57, 95%CI 1.02-2.42, respectively). The overlapping of violent situations (childhood trauma, IV and DUI) in some individuals presented here corroborates literature data suggesting that DUI can be an externalizing expression of a range of risky behavior, such as impulsiveness and aggressiveness. Moreover, while BD and higher impulsivity scores seem to act as risk factors for DUI, OCD was shown as a protective factor. These results corroborate the hypothesis that individuals with high risk for DUI could probably be identified by multidimensional assessment of cognitive, risky taking, and personality traits, which perhaps could facilitate the development of focused interventions.

The Quest to Extend Health Services to Vulnerable Substance Users in Rio de Janeiro, Brazil in the Context of an Unfolding Economic Crisis

Calls to address crack-cocaine use in Brazil among homeless and street-frequenting populations who are in urgent need of health services have questioned the capacity of the Brazilian Unified Health System to attend to the nation's most marginalized citizens. In recent years, Brazil has launched several actions to escalate care for substance users, yet many obstacles hindering accessibility and effectiveness of services remain. Paradoxically, these actions have been implemented in the context of a growing economic crisis, and expanding services for a population of poor and stigmatized substance users while cutting other government programs tends to elicit harsh criticism from citizens. In consequence of such prospects, this commentary aims to discuss barriers marginalized substance users face in accessing health services that are at risk of worsening with government cutbacks. Using Rio de Janeiro as an example, we explore two primary issues: the resource-strained, under-staffed and decentralized nature of the Brazilian Unified Health System and the pervading stigma that bars vulnerable citizens from official structures and services. Abandoning initiated government efforts to increase access to health services would risk maintaining vulnerable citizens at the margins of public structures, inhibiting the opportunity to offer this population humane and urgently needed treatment and care.

Mind the gap: implementation challenges break the link between HIV/AIDS research and practice

Sampling strategies such as respondent-driven sampling (RDS) and time-location sampling (TLS) offer unique opportunities to access key populations such as men who have sex with men (MSM) and transgender women. Limited work has assessed implementation challenges of these methods. Overcoming implementation challenges can improve research quality and increase uptake of HIV services among key populations. Drawing from studies using RDS in Brazil and TLS in Peru, we summarize challenges encountered in the field and potential strategies to address them. In Brazil, study site selection, cash incentives, and seed selection challenged RDS implementation with MSM. In Peru, expansive geography, safety concerns, and time required for study participation complicated TLS implementation with MSM and transgender women. Formative research, meaningful participation of key populations across stages of research, and transparency in study design are needed to link HIV/AIDS research and practice. Addressing implementation challenges can close gaps in accessing services among those most burdened by the epidemic.
