Self-care and risk reduction habits in older injection drug users with chronic wounds: a cross-sectional study

Diagnosis and Management of Intravenous Drug Users' Chronic Wounds: A Case Series Collection of a Single Center

Background: Intravenous drug users (IVDUs) represent a very small group of patients affected by chronic wounds (CWs). Objectives: To assess the risk factors for CWs in IVDUs, to improve their treatment. Methods: A retrospective review of 7 IVDUs with CWs was performed at the Dermatology of the University of Bologna. Results: A history of 10 years of the most frequent injection was heroin in the gaiter area. The most observed comorbidities were HIV, HCV and HBV. They were treated most with an alginate with silver dressing with an average follow-up of 2.8 years. Conclusions: We would like to highlight the importance of clinical history in this type of patients and that in our experience specialized skin wounds risk assessment and management could be useful, aside from traditional compression therapy.

Ageing and older people who use illicit opioids, cocaine or methamphetamine: a scoping review and literature map

AIMS

To provide an overview of research literature on ageing and older people who use illicit opioids and stimulants by documenting the conceptual frameworks used and content areas that have been investigated.

METHODS

We conducted a scoping review of literature relating to ageing and older people who use illicit stimulants and opioids, defining 'older' as 40 years and above. Primary studies, secondary studies and editorials were included. Searches were conducted in PubMed and Embase in July 2020 and March 2021; the Cochrane library was searched in November 2021. Charted data included methodological details, any conceptual frameworks explicitly applied by authors and the content areas that were the focus of the publication. We developed a hierarchy of content areas and mapped this to provide a visual guide to the research area.

RESULTS

Of the 164 publications included in this review, only 16 explicitly applied a conceptual framework. Seven core content areas were identified, with most publications contributing to multiple content areas: acknowledgement of drug use among older people (n = 64), health status (n = 129), health services (n = 109), drug use practices and patterns (n = 84), social environments (n = 74), the criminal legal system (n = 28) and quality of life (n = 15).

CONCLUSIONS

The literature regarding older people who use illicit drugs remains under-theorized. Conceptual frameworks are rarely applied and few have been purposely adapted to this population. Health status and health services access and use are among the most frequently researched topics in this area.

"The Drug Use Unfortunately isn't all Bad": Chronic Disease Self-Management Complexity and Strategy Among Marginalized People Who Use Drugs

Self-management programs improve health outcomes and self-management is recommended for chronic conditions. Yet chronic disease self-management supports have rarely been applied to people who use drugs (PWUD). Thus, our objective was to explore self-management experiences among marginalized PWUD. We used community-based participatory methods and conducted qualitative interviews. Participants self-identified as having long-term and past year experience using non-prescribed drugs, one other chronic condition, and socioeconomic marginalization. We analyzed the data using reflexive thematic analysis. Although many participants considered drug use a chronic health issue, self-medicating with non-prescribed drugs was also a key self-management strategy to address other health issues. Participants also described numerous other strategies, including cognitive and behavioral tactics. These findings highlight the need for a safe supply of pharmaceutical-grade drugs to support self-management among marginalized PWUD. Self-management supports should also be tailored to address relevant topics (e.g., harm reduction, withdrawal), include creative activities, and not hinder PWUD's agency.

Injecting drug use, the skin and vasculature

Damage to the skin, subcutaneous tissues and blood vessels are among the most common health harms related to injecting drug use. From a limited range of early reports of injecting-related skin and soft tissue damage there is now an increasing literature relating to new drugs, new contaminants and problems associated with unsafe injection practices. Clinical issues range from ubiquitous problems associated with repeated minor localised injection trauma to skin and soft tissue and infections around injection sites, to systemic blood infections and chronic vascular disease. The interplay of limited availability and access to sterile injecting equipment, poor injecting technique, compromised drug purity, drug toxicity and difficult personal and environmental conditions give rise to injection-related health harms. This review of injecting-related skin, soft tissue and vascular damage focuses on epidemiology and causation, clinical examination and investigation, treatment and prevention.

Negative experiences of pain and withdrawal create barriers to abscess care for people who inject heroin. A mixed methods analysis

BACKGROUND

Skin and soft tissue infections (SSTIs) are prevalent among people who inject heroin (PWIH). Delays in seeking health care lead to increased costs and potential mortality, yet the barriers to accessing care among PWIHs are poorly understood.

METHODS

We administered a quantitative survey (N = 145) and conducted qualitative interviews (N = 12) with PWIH seeking syringe exchange services in two U.S. cities.

RESULTS

66% of participants had experienced at least one SSTI. 38% reported waiting two weeks or more to seek care, and 57% reported leaving the hospital against medical advice. 54% reported undergoing a drainage procedure performed by a non-medical professional, and 32% reported taking antibiotics that were not prescribed to them. Two of the most common reasons for these behaviors were fear of withdrawal symptoms and inadequate pain control, and these reasons emerged as prominent themes in the qualitative findings. These issues are often predicated on previous negative experiences and exacerbated by stigma and an asymmetrical power dynamic with providers, resulting in perceived barriers to seeking and completing care for SSTIs.

CONCLUSIONS

For PWIH, unaddressed pain and withdrawal symptoms contribute to profoundly negative health care experiences, which then generate motivation for delaying care SSTI seeking and for discharge against medical advice. Health care providers and hospitals should develop policies to improve pain control, manage opioid withdrawal, minimize prejudice and stigma, and optimize communication with PWIH. These barriers should also be addressed by providing medical care in accessible and acceptable venues, such as safe injection facilities, street outreach, and other harm reduction venues.

Experiences with skin and soft tissue infections among people who inject drugs in Philadelphia: A qualitative study

OBJECTIVES

To understand how people who inject drugs (PWID) experience skin and soft tissue infections (SSTI) and make decisions to seek or delay medical treatment.

METHODS

We conducted semi-structured, in-depth interviews in 2015 with 19 PWID at a syringe exchange program in Philadelphia. We analyzed the data using standard qualitative techniques.

RESULTS

PWID described adequate knowledge about SSTI, although they could not always implement knowledge about SSTI prevention due to environmental constraints. Participants reported different experiences with incident SSTI. Some sought immediate medical care at initial presentation. Most, however, waited to seek care. Previous positive and negative healthcare experiences, both in general -including stigma and withdrawal- and specific to SSTI, influenced this decision. Among those who delayed medical care, some reported self-treatment, including increased drug use for pain control, and lancing and draining their own wounds.

CONCLUSION

Reducing the incidence of SSTI and promoting earlier treatment are important public health priorities. Both require ongoing attention and improvements to the environments in which PWID inject and receive care.

Perceptions about supervised injection facilities among people who inject drugs in Philadelphia

BACKGROUND

People who inject drugs (PWID) are at high risk for infectious diseases, skin and soft tissue infections, and overdose. However, these harms are all avoidable when sterile injection equipment, hygienic places to inject, and medical care are accessible. Unfortunately, many PWID in the U.S lack these resources. The most vulnerable are forced to inject in public spaces, where individual risks are high and communal harms are sometimes many. Supervised Injection Facilities (SIFs) are an established intervention for reducing these harms. Despite positive experiences in other countries, little research explores how PWID in the U.S. perceive the value of such facilities.

METHODS

We conducted a freelisting exercise with PWID (n=42) and healthcare providers (n=20) at a syringe exchange program (SEP) that provides comprehensive clinical and social services in Philadelphia to inform in-depth semi-structured interviews with PWID (n=19) at the same location.

RESULTS

Participants expressed support for a potential SIF as a valuable public health intervention. They suggested that an SIF would improve PWID health while reducing the public disorder associated with injecting drugs in public. The latter was especially important to participants without stable housing, whose decision to inject furtively in secluded places was often motivated by desire not to upset community members, and particularly children. These participants acknowledged that such seclusion elevated the risk of fatal overdose. Despite similarly positive perceptions about an SIF, participants with stable housing reported that they would prefer to continue injecting at home.

CONCLUSION

Results both confirm and extend prior research about PWID and SIFs. Participants expressed support for SIFs as in prior survey research in the U.S. and in other countries. Facility location and housing status were identified as important determinants of facility use. Results extend prior research by illuminating PWID perceptions in the U.S. including motivations grounded in concern for public order.

Willingness to use a supervised injection facility among young adults who use prescription opioids non-medically: a cross-sectional study

Background

Supervised injection facilities (SIFs) are legally sanctioned environments for people to inject drugs under medical supervision. SIFs currently operate in ten countries, but to date, no SIF has been opened in the USA. In light of increasing overdose mortality in the USA, this study evaluated willingness to use a SIF among youth who report non-medical prescription opioid (NMPO) use.

Methods

Between January 2015 and February 2016, youth with recent NMPO use were recruited to participate in the Rhode Island Young Adult Prescription Drug Study (RAPiDS). We explored factors associated with willingness to use a SIF among participants who had injected drugs or were at risk of initiating injection drug use (defined as having a sex partner who injects drugs or having a close friend who injects).

Results

Among 54 eligible participants, the median age was 26 (IQR = 24–28), 70.4% were male, and 74.1% were white. Among all participants, when asked if they would use a SIF, 63.0% answered “Yes”, 31.5% answered “No”, and 5.6% were unsure. Among the 31 participants reporting injection drug use in the last six months, 27 (87.1%) reported willingness to use a SIF; 15 of the 19 (78.9%) who injected less than daily reported willingness, while all 12 (100.0%) of the participants who injected daily reported willingness. Compared to participants who were unwilling or were unsure, participants willing to use a SIF were also more likely to have been homeless in the last six months, have accidentally overdosed, have used heroin, have used fentanyl non-medically, and typically use prescription opioids alone.

Conclusions

Among young adults who use prescription opioids non-medically and inject drugs or are at risk of initiating injection drug use, more than six in ten reported willingness to use a SIF. Established risk factors for overdose, including homelessness, history of overdose, daily injection drug use, heroin use, and fentanyl misuse, were associated with higher SIF acceptability, indicating that young people at the highest risk of overdose might ultimately be the same individuals to use the facility. Supervised injection facilities merit consideration to reduce overdose mortality in the USA.

Injection-site vein loss and soft tissue abscesses associated with black tar heroin injection: A cross-sectional study of two distinct populations in USA

BACKGROUND

Injection-site vein loss and skin abscesses impose significant morbidity on people who inject drugs (PWID). The two common forms of street heroin available in the USA include black tar and powder heroin. Little research has investigated these different forms of heroin and their potential implications for health outcomes.

METHODS

A multiple-choice survey was administered to a sample of 145 participants seeking services at reduction facilities in both Sacramento, CA and greater Boston, MA, USA. Multivariate regression models for reporting one or more abscesses in one year, injection-site veins lost in six months, and soft tissue injection.

RESULTS

Participants in Sacramento exclusively used black tar (99%), while those in Boston used powder heroin (96%). Those who used black tar heroin lost more injection-site veins (β=2.34, 95% CI: 0.66-4.03) and were more likely to report abscesses (AOR=7.68, 95% CI: 3.01-19.60). Soft tissue injection was also associated with abscesses (AOR=4.68, 95% CI: 1.84-11.93). Consistent venous access (AOR: 0.088, 95% CI: 0.011-0.74) and losing more injection sites (AOR: 1.22, 95% CI: 1.03-1.45) were associated with soft tissue injection.

CONCLUSION

Use of black tar heroin is associated with more frequent abscesses and more extensive vein loss. Poor venous access predisposes people who inject drugs to soft tissue injection, which may constitute a causal pathway between black tar heroin injection and abscess formation. The mechanisms by which black tar heroin contributes to vein loss and abscess formation must be further elucidated in order to develop actionable interventions for maintaining vein health and decreasing the abscess burden. Potential interventions include increased access to clean injection equipment and education, supervised injection facilities, opioid substitution therapy, and supply chain interventions targeting cutting agents.

Nationwide increase in hospitalizations for heroin-related soft tissue infections: Associations with structural market conditions

INTRODUCTION

Little is known about trends in national rates of injection-related skin and soft tissue infections (SSTI) and their relationship to the structural risk environment for heroin users. Use of Mexican-sourced "Black Tar" heroin, predominant in western US states, may have greater risk for SSTI compared with eastern US powder heroin (Colombian-sourced) due to its association with non-intravenous injection or from possible contamination.

METHODS

Using nationally representative hospital admissions data from the Nationwide Inpatient Sample and heroin price and purity data from the Drug Enforcement Administration, we looked at rates of hospital admissions for opiate-related SSTI (O-SSTI) between 1993 and 2010. Regression analyses examined associations between O-SSTI and heroin source, form and price.

RESULTS

Hospitalization rates of O-SSTI doubled from 4 to 9 per 100,000 nationally between 1993 and 2010; the increase concentrated among individuals aged 20-40. Heroin market features were strongly associated with changes in the rate of SSTI. Each $100 increase in yearly heroin price-per-gram-pure was associated with a 3% decrease in the rate of heroin-related SSTI admissions. Mexican-sourced-heroin-dominant cities had twice the rate of O-SSTI compared to Colombian-sourced-heroin-dominant cities.

DISCUSSION

Heroin-related SSTI are increasing and structural factors, including heroin price and source-form, are associated with higher rates of SSTI hospital admissions. Clinical and harm reduction efforts should educate heroin users on local risk factors, e.g., heroin type, promote vein health strategies and provide culturally sensitive treatment services for persons suffering with SSTI.
