Jones JD, Chaple M, Rozen S, DelaCuesta C, Sosa ES, Bryant K. Empirical assessment of wounds among people who use substances. Drug Alcohol Depend 2024; 262:111375. [PMID: 38971028 DOI: 10.1016/j.drugalcdep.2024.111375] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/07/2024] [Revised: 06/17/2024] [Accepted: 06/18/2024] [Indexed: 07/08/2024]
Abstract
BACKGROUND Wounds are a significant source of morbidity among people who use substances (PWUS). This project sought to identify the incidence and severity of wounds among PWUS in the South Bronx, a region of New York City with one of the highest morbidities of substance use disorder. METHODS This study recruited PWUS within the past 30 days. Research staff were trained to document the presence and severity of wounds. The primary outcome measure was the incidence of wounds. Acceptability of on-the-street wound care was assessed by the number of participants encountered. The association between participant characteristics and wounds was also evaluated. RESULTS In total, 586 PWUS were assessed (19.4 % female: 69 % Hispanic; 23 % Black; 5 % White). Heroin (65.7 %) and psychostimulants (58.3 %) were the most commonly used drugs. Approximately 23 % of outreach recipients disclosed a wound. Among those with a wound, 60.9 % reported one wound, 27.8 % had two wounds, and 11.3 % had three or more wounds. Small wounds (approximately the size of a cherry) were the most common (78.6 %). Recent use of stimulants or heroin, along with intravenous use of any substance were significantly associated with having a wound. CONCLUSIONS This study found that drug-related wounds were common among PWUS. Toxicology data from other sources indicate that xylazine was present in the NYC market at the time, though its prevalence among the current sample is difficult to determine. The occurrence and severity of substance-related wounds in NYC should continue to be monitored as a function of changes in the xylazine adulteration.

Clin Infect Dis 2024; 78:1443-1450. [PMID: 38315893 PMCID: PMC11175704 DOI: 10.1093/cid/ciae056] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2023] [Revised: 01/03/2024] [Accepted: 01/19/2024] [Indexed: 02/07/2024] Open
Abstract
BACKGROUND People who inject drugs (PWID) are at increased risk of community-acquired Staphylococcus aureus bacteremia (CA-SAB), but little is known about clinical outcomes of CA-SAB in PWID compared with the wider population of patients with CA-SAB. METHODS Three national datasets were linked to provide clinical and mortality data on patients hospitalized with CA-SAB in England between 1 January 2017 and 31 December 2020. PWID were identified using the International Classification of Diseases, Tenth Revision code for "mental health and behavioral disorder due to opioid use" (F11). Multivariable logistic regression was used to estimate adjusted odds ratios (aORs) for associations of PWID with 30-day all-cause mortality and 90-day hospital readmission. RESULTS In 10 045 cases of CA-SAB, 1612 (16.0%) were PWID. Overall, 796 (7.9%) patients died within 30 days of CA-SAB admission and 1189 (11.8%) patients were readmitted to hospital within 90 days of CA-SAB. In those without infective endocarditis, there was strong evidence of lower odds of mortality among PWID compared with non-PWID (aOR, 0.47 [95% confidence interval {CI}: .33-.68]; P < .001), whereas there was no association in CA-SAB case fatality with endocarditis (aOR, 1.40 [95% CI: .87-2.25]; P = .163). PWID were less likely to be readmitted within 90 days of CA-SAB (aOR, 0.79 [95% CI: .65-.95]; P = .011). CONCLUSIONS In this large cohort study of patients with CA-SAB in England, PWID had lower odds of death in the absence of endocarditis and lower odds of readmission within 90 days compared to non-PWID patients. This study highlights the overrepresentation of PWID among patients with CA-SAB nationally.

Abstract
INTRODUCTION Cutaneous abscesses are a common complication of intravenous substance use. Although these skin and soft tissue infections represent one of the main causes of emergency room visits and hospitalizations in people who inject drugs (PWID), data on their prevalence and causes are scarce. The present study was part of the larger ANRS-OUTSIDER project and aimed to study the factors associated with skin abscesses in PWID, focusing in particular on the different stages of injection. METHOD Analyses were based on data of the 164 persons who regularly injected psychoactive substances participating in the French ANRS-OUTSIDER project. A face-to-face questionnaire collected data on sociodemographics, substance use, injection practices, and experience of skin abscesses in the previous six months. Factors associated with skin abscesses were studied using a logistic regression model. RESULTS Of the 140 participants for whom abscess data were recorded at inclusion, 35% reported having a skin abscess in the previous six months. Factors associated with skin abscesses were: benefiting from universal health coverage (PUMA/CMU/AME) (Odd ratio (OR) = 0.28, confidence interval (CI) à 95%=0.08-0.99), finding the vein to inject by touch (OR=3.44, 95% CI=1.41-8.43) and licking the needle before injection (OR=5.16, 95% CI=1.10-24.30). CONCLUSION Our results highlight that skin abscesses were very frequent among the complications observed in our sample of French PWID, and that certain injection practices fostered their occurrence. These data will provide stakeholders with useful information to improve prevention and harm reduction messages for PWID.

Development, acceptability and feasibility of a personalised, behavioural intervention to prevent bacterial skin and soft tissue infections among people who inject drugs: a mixed-methods Person-Based Approach study. Harm Reduct J 2023; 20:114. [PMID: 37608267 PMCID: PMC10463350 DOI: 10.1186/s12954-023-00823-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2022] [Accepted: 07/10/2023] [Indexed: 08/24/2023] Open
Abstract
BACKGROUND Skin and soft tissue infections (SSTI) among people who inject drugs (PWID) are a public health concern. This study aimed to co-produce and assess the acceptability and feasibility of a behavioural intervention to prevent SSTI. METHODS The Person-Based Approach (PBA) was followed which involves: (i) collating and analysing evidence; (ii) developing guiding principles; (iii) a behavioural analysis; (iv) logic model development; and (v) designing and refining intervention materials. Co-production activities with target group representatives and key collaborators obtained feedback on the intervention which was used to refine its design and content. The intervention, harm reduction advice cards to support conversation between service provider and PWID and resources to support safer injecting practice, was piloted with 13 PWID by four service providers in Bristol and evaluated using a mixed-methods approach. Semi-structured interviews were conducted with 11 PWID and four service providers. Questionnaires completed by all PWID recorded demographic characteristics, SSTI, drug use and treatment history. Interviews were analysed thematically and questionnaires were analysed descriptively. RESULTS Published literature highlighted structural barriers to safer injecting practices, such as access to hygienic injecting environments and injecting practices associated with SSTI included: limited handwashing/injection-site swabbing and use of too much acidifier to dissolve drugs. Co-production activities and the literature indicated vein care and minimisation of pain as PWID priorities. The importance of service provider-client relationships and non-stigmatising delivery was highlighted through the co-production work. Providing practical resources was identified as important to address environmental constraints to safer injecting practices. Most participants receiving the intervention were White British, male, had a history of SSTI and on average were 43.6 years old and had injected for 22.7 years. The intervention was well-received by PWID and service providers. Intervention content and materials given out to support harm reduction were viewed positively. The intervention appeared to support reflections on and intentions to change injecting behaviours, though barriers to safer injecting practice remained prominent. CONCLUSIONS The PBA ensured the intervention aligned to the priorities of PWID. It was viewed as acceptable and mostly feasible to PWID and service providers and has transferability promise. Further implementation alongside broader harm reduction interventions is needed.

Abstract
BACKGROUND People who use drugs (PWUD) frequent emergency departments at a higher rate than the general population, and experience a greater frequency of soft tissue infections, pneumonia, and chronic conditions such as, HIV/AIDs and hepatitis C. This population has distinct health care considerations (e.g. withdrawal management) and are also more likely to leave or be discharged from hospital against medical advice. METHODS This study examines the experiences of PWUD who have left or been discharged from hospital against medical advice to understand the structural vulnerabilities that shape experiences with emergency departments. Semi-structured qualitative interviews were conducted with 30 PWUD who have left or been discharged from hospital against medical advice within the past two years as part of a larger study on hospital care and drug use in Vancouver, Canada. RESULTS Findings characterize the experiences and perceptions of PWUD in emergency department settings, and include: (1) stigmatization of PWUD and compounding experiences of discrimination; (2) perceptions of overall neglect; (3) inadequate pain and withdrawal management; and (4) leaving ED against medical advice and a lack of willingness to engage in future care. CONCLUSIONS Structural vulnerabilities in ED can negatively impact the care received among PWUD. Findings demonstrate the need to consider how structural factors impact care for PWUD and to leverage existing infrastructure to incorporate harm reduction and a structural competency focused care. Findings also point to the need to consider how withdrawal and pain are managed in emergency department settings.

Abstract
BACKGROUND People who inject drugs (PWID) are at an amplified vulnerability for experiencing a multitude of harms related to their substance use, including viral (e.g. HIV, Hepatitis C) and bacterial infections (e.g. endocarditis). Implementation of evidence-based interventions, such as syringe services programs (SSPs), remains imperative, particularly in locations at an increased risk of HIV outbreaks. This study aims to identify communities in Florida that are high-priority locations for SSP implementation by examining state-level data related to the substance use and overdose crises. METHODS State-level surveillance data were aggregated at the ZIP Code Tabulation Area (ZCTA) (n = 983) for 2017. We used confirmed cases of acute HCV infection as a proxy of injection drug use. Least Absolute Selection and Shrinkage Operator (LASSO) regression was used to develop a machine learning model to identify significant indicators of acute HCV infection and high-priority areas for SSP implementation due to their increased vulnerability to an HIV outbreak. RESULTS The final model retained three variables of importance: (1) the number of drug-associated skin and soft tissue infection hospitalizations, (2) the number of chronic HCV infections in people aged 18-39, and 3) the number of drug-associated endocarditis hospitalizations. High-priority SSP implementation locations were identified in both urban and rural communities outside of current Ending the HIV Epidemic counties. CONCLUSION SSPs are long researched, safe, and effective evidence-based programs that offer a variety of services that reduce disease transmission and assist with combating the overdose crisis. Opportunities to increase services in needed regions across the state now exist in Florida as supported by the expansion of the Infectious Disease Elimination Act of 2019. This study provides details where potential areas of concern may be and highlights regions where future evidence-based harm reduction programs, such as SSPs, would be useful to reduce opioid overdoses and disease transmission among PWID.Key messagesThe rate of acute HCV in Florida in 2017 was 1.9 per 100,000, nearly twice the national average.Serious injection related infections among PWID are significant indicators of acute HCV infection.High-priority SSP implementation locations in Florida were identified in both urban and rural communities, including those outside of current Ending the HIV Epidemic counties.

Abstract
INTRODUCTION People who inject drugs are at risk of hospitalisation with injection-related infections (IRI). We audited the clinical features, microbiology and management of IRI at a tertiary service in Melbourne to describe the burden and identify quality improvement opportunities. METHODS We performed retrospective review of IRI admissions from January 2017 to April 2019. We extracted admissions where ICD-10 codes or triage text suggested injecting drug use, and the diagnosis suggested IRI. We reviewed these for eligibility and extracted data using a standardised form. We performed mixed-effects logistic regression to determine predictors of unplanned discharge. RESULTS From 574 extracted candidate admissions, 226 were eligible, representing 178 patients. Median age was 41 years (interquartile range 36-47), 66% (117/178) male and 49% (111/226) had unstable housing. Over 50% (96/178) had a psychiatric diagnosis and 35% (62/178) were on opioid agonist therapy (OAT) on admission. Skin and soft tissue infection was the most common IRI (119/205, 58%), followed by bacteraemia (36/205, 18%) and endocarditis (26/205, 13%). Management included addictions review (143/226, 63%), blood-borne virus screening (115/226, 51%), surgery (77/226, 34%) and OAT commencement (68/226, 30%). Aggression events (54/226, 15%) and unplanned discharge (69/226, 30%) complicated some admissions. Opioid use without OAT was associated with almost 3-fold increased odds of unplanned discharge compared to no opioid use (odds ratio 2.90, 95% confidence interval 1.23, 6.85, p = 0.015). DISCUSSION AND CONCLUSION Comorbidities associated with IRI may be amenable to opportunistic intervention during hospitalisation. Further research is needed to develop optimal models of care for this vulnerable patient group.

The impact of opioid agonist treatment on hospitalisations for injecting-related diseases among an opioid dependent population: A retrospective data linkage study. Drug Alcohol Depend 2022; 236:109494.

Abstract
BACKGROUND Injecting-related bacterial and fungal infections cause substantial illness and disability among people who use illicit drugs. Opioid agonist treatment (OAT) reduces injecting frequency and the transmission of blood borne viruses. We estimated the impact of OAT on hospitalisations for non-viral infections and examine trends in incidence over time. METHODS We conducted a retrospective cohort study using linked administrative data. The cohort included 47 163 individuals starting OAT between August 2001 and December 2017 in New South Wales, Australia, with 454 951 person-years of follow-up. The primary outcome was hospitalisation for an injecting-related disease. The primary exposure was OAT status (out of OAT, first four weeks of OAT, and OAT retention [i.e., more than four weeks in treatment]). Covariates included demographic characteristics, year of hospitalisation, and recent clinical treatment. RESULTS 9122 participants (19.3%) had at least one hospitalisation for any injecting-related disease. Compared to time out of treatment, retention on OAT was associated with a reduced rate of injecting-related diseases (adjusted rate ratio[ARR]=0.92; 95%CI 0.87-0.97). The first four weeks of treatment was associated with an increased rate (ARR 1.53, 95%CI 1.38-1.70), which we believe is explained by referral pathways between hospital and community OAT services. The age-adjusted incidence rates of hospitalisations for any injecting-related disease increased from 34.8 (95% CI =30.2-40.0) per 1000 person-years in 2001 to 54.9 (95%CI=51.3-58.8) in 2017. INTERPRETATION Stable OAT is associated with reduced hospitalisations for injecting-related bacterial infections; however, OAT appears insufficient to prevent these harms as the rate of these infections is increasing in Australia.

Abstract
BACKGROUND Syringe services programs (SSPs) remain highly effective, cost-saving interventions for the prevention of blood-borne infections among people who inject drugs. However, there have been restrictions regarding financial resources allocated to these programs, particularly in the US South. This study aimed to provide cost data regarding the implementation and first-year operations of an academic-based SSP utilizing fixed and mobile strategies, including the integration of onsite wound care. METHODS We conducted a micro-costing study that retrospectively collected detailed resource utilization and unit cost data for both the fixed and mobile SSP strategies, including onsite wound care, from both healthcare and societal perspectives. A three-step approach was used to identify, measure, and value intervention costs, and cost components were categorized into implementation, variable program, and time-dependent costs. Sensitivity analysis was performed to examine the impact of SSP operational changes (i.e., needs-based distribution and opt-out HIV/HCV testing) on the cost-per-participant. Cost data we presented as overall cost and cost-per-participant adjusted to 2017 US dollars. RESULTS A total of 452 and 129 participants enrolled in fixed and mobile SSP services, respectively. The total cost associated with implementation and first year operations for the fixed site was $407,217.22 or $729.72 per participant and $311,625.52 or $2415.70 per participant for the mobile unit. The largest cost component for both modalities was time-dependent costs (personnel and overhead), while intervention materials (syringes, injection equipment, naloxone) were less than 15% of the total program cost. DISCUSSION/CONCLUSION Implementation and operation of new SSP models continue to be low cost compared to treatment for the multitude of harms PWID face without access to evidence-based prevention. Future cost-effectiveness and cost-benefit analyses integrating a comprehensive SSP model within an academic institution, including onsite wound care and other medical services, will provide a more comprehensive understanding of this model, and state-level policy action must be taken to lift the prohibition of state and local funds for the implementation, sustainability, and maintenance of these programs in Florida.

Abstract
INTRODUCTION The main harm reduction interventions for people who inject drugs (PWID) are supervised injection facilities, needle and syringe programmes and opioid agonist treatment. Current evidence supporting their implementation and operation underestimates their usefulness by excluding skin, soft tissue and vascular infections (SSTVIs) and anoxic/toxicity-related brain injury from cost-effectiveness analyses (CEA). Our goal is to conduct a comprehensive CEA of harm reduction interventions in a setting with a large, dispersed, heterogeneous population of PWID, and include prevention of SSTVIs and anoxic/toxicity-related brain injury as measures of benefit in addition to HIV, hepatitis C and overdose morbidity and mortalities averted. METHODS AND ANALYSIS This protocol describes how we will develop an open, retrospective cohort of adult PWID living in Québec between 1 January 2009 and 31 December 2020 using administrative health record data. By complementing this data with non-linkable paramedic dispatch records, regional monthly needle and syringe dispensation counts and repeated cross-sectional biobehavioural surveys, we will estimate the hazards of occurrence and the impact of Montréal's harm reduction interventions on the incidence of drug-use-related injuries, infections and deaths. We will synthesise results from our empirical analyses with published evidence to simulate infections and injuries in a hypothetical population of PWID in Montréal under different intervention scenarios including current levels of use and scale-up, and assess the cost-effectiveness of each intervention from the public healthcare payer's perspective. ETHICS AND DISSEMINATION This study was approved by McGill University's Institutional Review Board (Study Number: A08-E53-19B). We will work with community partners to disseminate results to the public and scientific community via scientific conferences, a publicly accessible report, op-ed articles and open access peer-reviewed journals.

Bacterial infections in people who inject psychoactive substances: An observational study in a French university hospital. Therapie 2021; 76:539-547. [PMID: 34183194 DOI: 10.1016/j.therap.2021.05.008] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2020] [Revised: 05/04/2021] [Accepted: 05/25/2021] [Indexed: 11/22/2022]
Abstract
AIM OF THE STUDY To describe bacterial infections in injection drug users (IDUs) hospitalized at Montpellier University Hospital, France, and to identify factors that might influence the development of local or systemic infections. METHODS This cross-sectional observational monocentric study prospectively included bacterial infections in IDUs hospitalized at Montpellier University Hospital between 2012 and 2018. Types of infection (local or systemic) were described and compared to identify specific features (injection practices). RESULTS The study included 144 bacterial infections (56% of local infections and 44% of systemic infections) concerning 117 IDUs. The most common infection types were abscesses (50%), skin and soft tissue infections (33%), bacteremia/sepsis (20%), endocarditis (17%), and bone and joint infections (16%). Patients were mainly men (n=94; 80%), and the median age was 40 years [IQR25-75: 34-47]. Four deaths related to systemic infection were reported. The most frequent injected substances were cocaine, opioid maintenance treatments (OMT), and opioids. According to the multivariate analysis, factors associated with the occurrence of systemic infections were number of injection (OR 2.59 [1.07-6.27]; P=0.034) and injection of at least one opioid (OR 3.52 [1.28-9.72]; P=0.015). CONCLUSION Different types of bacterial infections, local or systemic, are observed in IDUs. Skin infections are quite common, but other infection types also are reported, with sometimes serious consequences. It is already known that injection practices are contributing factors in infection development, but the type of injected psychoactive substance(s) also may have an influence.

Abstract
Introduction Skin and soft tissue infections (SSTIs) are among the leading causes of morbidity and mortality for people who inject drugs (PWID). Studies demonstrate that certain injection practices correlate with SSTI incidence among PWID. The opioid epidemic in the USA has particularly affected rural communities, where access to prevention and treatment presents unique challenges. This study aims to estimate unsafe injection practices among rural-dwelling PWID; assess treatments utilized for injection related SSTIs; and gather data to help reduce the overall risk of injection-related SSTIs. Methods Thirteen questions specific to SSTIs and injection practices were added to a larger study assessing unmet health care needs among PWID and were administered at six syringe exchange programs in rural Wisconsin between May and July 2019. SSTI history prevalence was estimated based on infections reported within one-year prior of response and was compared to self-reported demographics and injection practices. Results Eighty responses were collected and analyzed. Respondents were white (77.5%), males (60%), between the ages 30 and 39 (42.5%), and have a high school diploma or GED (38.75%). The majority of respondents (77.5%) reported no history of SSTI within the year prior to survey response. Females were over three times more likely to report SSTI history (OR = 3.07, p = 0.038) compared to males. Water sources for drug dilution (p = 0.093) and frequency of injecting on first attempt (p = 0.037), but not proper skin cleaning method (p = 0.378), were significantly associated with a history of SSTI. Injecting into skin (p = 0.038) or muscle (p = 0.001) was significantly associated with a history of SSTI. Injection into veins was not significantly associated with SSTI (p = 0.333).
Conclusion Higher-risk injection practices were common among participants reporting a history of SSTIs in this rural sample. Studies exploring socio-demographic factors influencing risky injection practices and general barriers to safer injection practices to prevent SSTIs are warranted. Dissemination of education materials targeting SSTI prevention and intervention among PWID not in treatment is warranted.

Abstract
INTRODUCTION People who inject drugs (PWID) commonly experience harms related to their injecting, many of which are consequences of modifiable drug use practices. There is currently a gap in our understanding of how certain injecting-related injuries and diseases (IRID) cluster together, and socio-demographic and drug use characteristics associated with more complex clinical profiles. METHOD Surveys were conducted with 902 Australian PWID in 2019. Participants provided information regarding their drug use, and past month experience of the following IRID: artery injection, nerve damage, skin and soft tissue infection, thrombophlebitis, deep vein thrombosis, endocarditis, septic arthritis, osteomyelitis, and septicaemia. We performed a latent class analysis, grouping participants based on reported IRID and ran a class-weighted regression analysis to determine variables associated with class-membership. RESULTS One-third (34 %) of the sample reported any IRID. A 3-class model identified: 1) no IRID (73 %), moderate IRID (21 %), and 3) high IRID (6%) clusters. Re-using one`s own needles was associated with belonging to the high IRID versus moderate IRID class (ARRR = 2.38; 95 % CI = 1.04-5.48). Other factors, including daily injecting and past 6-month mental health problems were associated with belonging to moderate and high IRID classes versus no IRID class. CONCLUSION A meaningful proportion of PWID reported highly complex IRID presentations distinguished by the presence of thrombophlebitis and associated with greater re-use of needles. Increasing needle and syringe coverage remains critical in addressing the harms associated with injecting drug use and expanding the capacity of low-threshold services to address less severe presentations might aid in reducing IRID amongst PWID.

Factors associated with skin and soft tissue infections among people who inject drugs in the United Kingdom: A comparative examination of data from two surveys. Drug Alcohol Depend 2020; 213:108080. [PMID: 32526658 DOI: 10.1016/j.drugalcdep.2020.108080] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/21/2020] [Revised: 05/05/2020] [Accepted: 05/11/2020] [Indexed: 10/24/2022]
Abstract
BACKGROUND People who inject drugs (PWID) are at high risk of injection-related skin and soft tissue infections (SSTI). If not treated promptly, these can lead to serious health complications, which are a considerable healthcare burden. Data from two community surveys, with different approaches, were used to assess SSTI prevalence and associated factors among PWID to inform intervention implementation. METHODS Data were analysed from two surveys, a national surveillance survey (n=2,874; 2017-18) of infections among PWID in the United Kingdom (UK) and an in-depth survey (n=455; 2018-19) of SSTI among PWID based in London, UK. Multivariable logistic regression models were constructed to ascertain the factors associated with self-reported SSTI. RESULTS High prevalence of SSTI were reported in both samples: 52 % of participants from the national surveillance survey reported having SSTI within the preceding 12 months and 65 % of the London sample reported a lifetime history of SSTI. The factors associated with SSTI in both surveys were similar, including older age; number of years injecting; number of attempts required to inject into the vein; injecting into the hands, feet, groin or neck and re-using or sharing needles/syringes. CONCLUSIONS The number of PWID reporting SSTI in the UK is concerningly high. The two surveys used different recruitment approaches but found similar associations. We provide strong evidence of a relationship between venous access difficulty and SSTI. To stem the increase of SSTI and related complications in the UK, it is crucial that interventions attend to the underlying causes of venous damage among PWID.

Abstract
AIMS To summarize evidence on the frequency and predictors of health-care utilization among people who use illicit drugs. DESIGN Systematic search of MEDLINE, EMBASE and PsychINFO for observational studies reporting health-care utilization published between 1 January 2000 and 3 December 2018. We conducted narrative synthesis and meta-analysis following a registered protocol (identifier: CRD42017076525). SETTING AND PARTICIPANTS People who use heroin, powder cocaine, crack cocaine, methamphetamine, amphetamine, ecstasy/3,4-methylenedioxymethamphetamine (MDMA), cannabis, hallucinogens or novel psychoactive substances; have a diagnosis of 'substance use disorder'; or use drug treatment services. MEASUREMENTS Primary outcomes were the cumulative incidence (risk) and rate of care episodes in three settings: primary care, hospital admissions (in-patient) and emergency department (ED). FINDINGS Ninety-two studies were included, 84% from North America and Australia. Most studies focused on people using heroin, methamphetamine or crack cocaine, or who had a diagnosis of drug dependence. We were able to conduct a meta-analysis of rates across 25 studies reporting ED episodes and 25 reporting hospital admissions, finding pooled rates of 151 [95% confidence interval (CI) = 114-201] and 41 (95% CI = 30-57) per 100 person-years, respectively; on average 4.8 and 7.1 times more often than the general population. Heterogeneity was very high and was not explained by drugs used, country of study, recruitment setting or demographic characteristics. Predictors of health-care utilization were consistent across studies and included unstable housing, drug injection and mental health problems. Opioid substitution therapy was consistently associated with reduced ED presentation and hospital admission. There was minimal research on health-care utilization by people using ecstasy/MDMA, powder cocaine, hallucinogens or novel psychoactive substances. CONCLUSIONS People who use illicit drugs are admitted to emergency department or hospital several times more often than the general population.

Abstract
BACKGROUND People who inject drugs face several health issues because of unsafe injecting practices. We aimed to evaluate changes in supervised drug-injecting practices following the implementation of a face-to-face educational intervention. METHODS The national study ANRS-AERLI was conducted in 17 harm reduction (HR) facilities in France between 2011 and 2013. Eight offered the intervention and nine did not. We conducted a pre-post analysis focusing on injecting practices data, collected in the 8 HR facilities providing the intervention. The intervention consisted of providing face-to-face educational sessions including direct observation of injecting practices, counseling about safer injecting, and shared discussion. Injecting practices were collected following a checklist and classified as safe or unsafe. To assess changes in injecting practices, practices were compared before (at baseline) and after at least one educational session. FINDINGS Mixed logistic models showed that the 78 participants included were more likely to improve in the following drug-use steps: setting up a clean preparation area (Adjusted Odds Ratio (AOR) = 3.4, 95% Confidence Interval (95% CI) = 1.6-7.6), hand washing (AOR = 7.2, 95% CI = 3.1-16.4), skin cleaning (AOR = 5.6, 95% CI = 2.5-12.1), choice of safe injection site (AOR = 6.5, 95% CI = 1.5-28.8) and post-injection bleeding management (AOR = 12.8, 95% CI = 5.5-29.9). Furthermore, participants were less likely to lick their needles before injecting (AOR = 8.1, 95% CI = 1.5-43.4) and to perform booting/flushing (AOR = 2.5, 95% CI = 1.2-5.3). CONCLUSIONS The AERLI intervention seems to be effective in increasing safe drug-injecting practices.

Abstract
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.

Harris M, Brathwaite R, McGowan CR, Ciccarone D, Gilchrist G, McCusker M, O'Brien K, Dunn J, Scott J, Hope V. 'Care and Prevent': rationale for investigating skin and soft tissue infections and AA amyloidosis among people who inject drugs in London. Harm Reduct J 2018; 15:23. [PMID: 29739408 PMCID: PMC5941602 DOI: 10.1186/s12954-018-0233-y] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2018] [Accepted: 05/02/2018] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND Skin and soft tissue infections (SSTIs) are a leading cause of morbidity and mortality among people who inject drugs (PWID). International data indicate up to one third of PWID have experienced an SSTI within the past month. Complications include sepsis, endocarditis and amyloid A (AA) amyloidosis. AA amyloidosis is a serious sequela of chronic SSTI among PWID. Though there is a paucity of literature reporting on AA amyloidosis among PWID, what has been published suggests there is likely a causal relationship between AA amyloidosis and injecting-related SSTI. If left untreated, AA amyloidosis can lead to renal failure; premature mortality among diagnosed PWID is high. Early intervention may reverse disease. Despite the high societal and individual burden of SSTI among PWID, empirical evidence on the barriers and facilitators to injecting-related SSTI prevention and care or the feasibility and acceptability of AA amyloidosis screening and treatment referral are limited. This study aims to fill these gaps and assess the prevalence of AA amyloidosis among PWID. METHODS Care and Prevent is a UK National Institute for Health Research-funded mixed-methods study. In five phases (P1-P5), we aim to assess the evidence for AA amyloidosis among PWID (P1); assess the feasibility of AA amyloidosis screening, diagnostic and treatment referral among PWID in London (P2); investigate the barriers and facilitators to AA amyloidosis care (P3); explore SSTI protection and risk (P4); and co-create harm reduction resources with the affected community (P5). This paper describes the conceptual framework, methodological design and proposed analysis for the mixed-methods multi-phase study. RESULTS We are implementing the Care and Prevent protocol in London. The systematic review component of the study has been completed and published. Care and Prevent will generate an estimate of AA amyloidosis prevalence among community recruited PWID in London, with implications for the development of screening recommendations and intervention implementation. We aim to recruit 400 PWID from drug treatment services in London, UK. CONCLUSIONS Care and Prevent is the first study to assess screening feasibility and the prevalence of positive proteinuria, as a marker for AA amyloidosis, among PWID accessing drug treatment services. AA amyloidosis is a serious, yet under-recognised condition for which early intervention is available but not employed.

Abstract
BACKGROUND Abscesses commonly occur among people who inject drugs (PWID). However, whether the risks are comparable between males and females, and the impact of sex work on abscess risk is unclear. The goal of this study was to examine the contemporary associations of gender and sex work with the risk of abscesses in PWID. METHODS Combining data from two cross-sectional studies conducted in the Greater Boston Area with people at risk for HIV and hepatitis C virus (HCV), we used the following inclusion criteria: age 18-45 years and report of illicit or non-prescription drug injection within the 30 days prior to the survey. Information on demographics, injection-mediated risks, and sexual behaviors was collected using Audio Computer-Assisted Self-Interview Software. Multivariable logistic regressions were used to model associations. RESULTS The study sample included 298 people including 30% were female. Females were more likely than men to report sex work (28% vs. 16%, p = .012) and abscess during their lifetime (55% vs. 37% p = .004). Among the females, engaging in sex work increased by >5-fold the odds of reporting abscesses [Adjusted odds ratio 5.42; 95% CI: 1.27, 23.10]. There was no association between sex work and abscesses among men. DISCUSSION We found a female-specific association between sex work, injection drug use, and abscesses among PWID. Although the cross-sectional designs precluded causal inferences, longitudinal studies could enhance understanding of gender-associated risks for abscesses and inform the development of harm reduction interventions.

Association between harm reduction intervention uptake and skin and soft tissue infections among people who inject drugs. Drug Alcohol Depend 2017; 174:91-97.

Abstract
BACKGROUND Bacterial skin and soft tissue infections (SSTIs) are a health issue for people who inject drugs (PWID). There is a lack of evidence on the associations between harm reduction (HR) uptake and SSTIs. This paper examines the associations between the uptake of injecting equipment (IE) and opiate substitution treatment (OST) on SSTIs among PWID, and the injecting behaviours associated with having had an SSTI. This is the first large-scale, national study to examine the association between IE uptake and SSTIs. METHODS A cross-sectional, voluntary and anonymous survey was undertaken with PWID recruited from pharmacies/agencies providing IE across mainland Scotland during 2013-2014. Participants were asked: if they had an SSTI within the past year; about their uptake of HR within the past 6 months (including needle/syringes (N/S), paraphernalia and OST); and about their frequency of injecting, sharing of IE and re-use of own N/S. Data from 1876 PWID who had reported injecting within the past 6 months were analysed. FINDINGS In multivariate logistic regression, those with high combined IE-OST uptake (adjusted odds ratio [AOR] 0.614, 95% CI 0.458-0.823, p=0.001) and medium combined IE-OST uptake (AOR 0.725, 95% CI 0.546-0.962, p=0.026) had lower odds of having had an SSTI compared to those with low combined IE-OST uptake. CONCLUSIONS IE and OST uptake may reduce the level of SSTIs among PWID, suggesting increasing combined uptake may be beneficial. Nevertheless, a sizeable proportion of PWID with high HR uptake experienced SSTIs, suggesting the importance of other interventions.

Abstract
BACKGROUND Non-viral injecting-related injuries and diseases (IRID), such as abscesses and vascular damage, can result in significant morbidity and mortality if untreated. There has been no systematic assessment of the prevalence of non-viral IRID among people who inject drugs; this review aimed to address this gap, as well as identify risk factors for experience of specific IRID. METHODS We searched MEDLINE, Embase and CINAHL databases to identify studies on the prevalence of, or risk factors for, IRID directly linked to injecting in samples of people who inject illicit drugs. RESULTS We included 33 studies: 29 reported IRID prevalence in people who inject drugs, and 17 provided data on IRID risk factors. Skin and soft tissue infections at injecting sites were the most commonly reported IRID, with wide variation in lifetime prevalence (6-69%). Female sex, more frequent injecting, and intramuscular and subcutaneous injecting appear to be associated with skin and soft tissue infections at injecting sites. Cleaning injecting sites was protective against skin infections. Other IRID included infective endocarditis (lifetime prevalence ranging from 0.5-12%); sepsis (2-10%); bone and joint infections (0.5-2%); and thrombosis and emboli (3-27%). CONCLUSIONS There were significant gaps in the data, including a dearth of research on prevalence of IRID in low- and middle-income countries, and potential risk and protective factors for IRID. A consistent approach to measurement, including standardised definitions of IRID, is required for future research.

Abstract
Needle and syringe program (NSP) coverage is commonly used to assess NSP effectiveness. However, existing measures don't capture whether persons who inject drugs (PWIDs) stockpile syringes, an important and novel aspect of NSP coverage. In this study, we determine the extent of stockpiling in a sample of Australian PWIDs and assess whether including stockpiling enhances NSP coverage measures. As part of the Illicit Drug Reporting System study, PWIDs reported syringes procured and given away, total injections in the last month, and syringes currently stockpiled in 2014. We calculated NSP coverage with and without stockpiling to determine proportional change in adequate NSP coverage. We conducted receiver operating characteristic curve analysis to determine whether inclusion of stockpiled syringes in the measure improved sensitivity in discriminating cases and noncases of risky behaviors. Three-quarters of the sample reported syringe stockpiling, and stockpiling was positively associated with nonindigenous background, stable accommodation, no prison history, longer injecting careers, and more frequent injecting. Compared with previous measures, our measure was significantly better at discriminating cases of risky behaviors. Our results could inform NSP policy to loosen restricted-exchange practice, allowing PWIDs greater flexibility in syringe procurement practices, promoting greater NSP coverage, and reducing PWIDs' engagement in risky behaviors.

Abstract
OBJECTIVES Abscesses and chronic wounds are common among injection drug users (IDUs) though chronic wounds have been understudied. We assessed the risk factors associated with both acute and chronic wounds within a community-based population of IDUs frequenting the Baltimore City Needle Exchange Program (BNEP). METHODS We performed a cross-sectional study of BNEP clients aged 18 years or more who completed an in-person survey regarding active or prior wounds including abscesses (duration <8 weeks) and chronic wounds (duration ≥8 weeks), injection practices, and skin care. Factors associated with wounds were analyzed using univariate and multivariate logistic regressions. RESULTS Of the 152 participants, 63.2% were men, 49.3% were white, 44.7% were African American, 34.9% had any type of current wound, 17.8% had an active abscess, and 19.7% had a current chronic wound. Abscesses were more common in women (odds ratio [OR], 2.56; 95% confidence interval [CI], 1.10-5.97) and those reporting skin-popping (OR, 5.38; 95% CI, 1.85-15.67). In a multivariate model, risk factors for an abscess included injecting with a family member/partner (adjusted OR [AOR], 4.06; 95% CI, 0.99-16.58). In a multivariable analysis of current chronic wounds, cleaning skin with alcohol before injection was protective (AOR, 0.061; 95% CI, 0.0064-0.58). CONCLUSIONS Abscesses and chronic wounds were prevalent among a sample of IDUs in Baltimore. Abscesses were associated with injection practices, and chronic wounds seemed linked to varying skin and tool cleaning practices. There is a pressing need for wound-related education and treatment efforts among IDUs who are at greatest risk for skin-related morbidity.

Abstract
Background We surveyed a population of injection drug users (IDUs) frequenting the mobile Baltimore City Needle Exchange Program (BNEP) to investigate self-care factors associated with chronic wounds, a significant cause of morbidity especially among older IDUs. Methods Participants ≥18 years old completed a survey regarding chronic wounds (duration ≥8 weeks), injection and hygiene practices. Study staff visually verified the presence of wounds. Participants were categorized into four groups by age and wound status. Factors associated with the presence of chronic wounds in participants ≥45 years were analyzed using logistic regression. Results Of the 152 participants, 19.7% had a chronic wound. Of those with chronic wounds, 18 were ≥45 years old (60.0%). Individuals ≥45 years old with chronic wounds were more likely to be enrolled in a drug treatment program (Odds ratio (OR) 3.4, 95% Confidence interval (CI) 1.0–10.8) and less likely to use cigarette filters when drawing up prepared drug (OR 0.2, 95% CI 0.03–0.7) compared to the same age group without chronic wounds. Compared to individuals <45 years old without chronic wounds, individuals ≥45 with a chronic wound were more likely to report cleaning reused needles with bleach (OR 10.7, 95% CI 1.2–93.9) and to use the clinic, rather than an emergency room, as a primary source of medical care (OR 3.4, 95% CI 1.1–10.4). Conclusions Older IDUs with chronic wounds have different, and perhaps less risky, injection and hygiene behaviors than their peers and younger IDUs without wounds in Baltimore City. Because of these differences, older IDUs with wounds may be more receptive to community-based healthcare and substance abuse treatment messages.

Abstract
People who inject drugs (PWID) experience a high incidence of abscesses and chronic wounds. However, many PWID delay seeking care for their wounds. In 2012, the Baltimore Needle Exchange Program (BNEP) in Baltimore, Maryland, partnered with the Johns Hopkins Wound Healing Center to establish a mobile BNEP Wound Clinic. This clinic provided specialized wound care for BNEP patients. In sixteen months, the clinic treated 78 unique patients during 172 visits overall. On average, each visit cost the program $146.45, which was substantially less than clinic-based treatment. This program demonstrates that specialized wound care can be effectively provided through mobile outreach. A community-based service delivery approach might serve as a model for local health departments looking to improve the health of PWID.

Abstract
People who inject drugs (PWID) are vulnerable to infections and injuries at injection sites. The factors associated with reporting symptoms of these, seeking related advice, and hospital admission are examined. PWID were recruited in Birmingham, Bristol and Leeds using respondent-driven sampling (N = 855). During the preceding year, 48% reported having redness, swelling and tenderness (RST), 19% an abscess, and 10% an open wound at an injection site. Overall, 54% reported ⩾1 symptoms, with 45% of these seeking medical advice (main sources emergency departments and General Practitioners). Advice was often sought ⩾5 days after the symptom first appeared (44% of those seeking advice about an abscess, 45% about an open wound, and 35% for RST); the majority received antibiotics. Overall, 9·5% reported hospital admission during the preceding year. Ever being diagnosed with septicaemia and endocarditis were reported by 8·8% and 2·9%, respectively. Interventions are needed to reduce morbidity, healthcare burden and delays in accessing treatment.

Abstract
Background Use of the femoral vein for the injection of illicit drugs (i.e. groin injecting) has been linked to various health-related harms, including deep vein thrombosis. However, little is known about the prevalence of groin injecting and factors that predict this practice among people who inject drugs (PWID) in Thailand. We sought to investigate the prevalence and factors associated with groin injecting in Bangkok, Thailand. Methods Data were derived from the Mitsampan Community Research Project in Bangkok between July and October 2011. Multivariate logistic regression was used to identify factors associated with groin injecting in the last six months. Results Among 437 participants, 34.3% reported groin injecting in the last six months. In multivariate analyses, factors positively associated with groin injecting included: having higher than secondary education (adjusted odds ratio [AOR] = 1.59; 95% confidence interval [CI]: 1.00 – 2.56), weekly midazolam injection (AOR = 8.26; 95% CI: 5.04 – 14.06), and reports of having had drugs planted on oneself by police (AOR = 2.14; 95% CI: 1.37 – 3.36). Conclusions Over one-third of our sample of Thai PWID reported recent groin injecting. Frequent midazolam injection and higher education were found to be associated with groin injecting. That high intensity PWID were more likely to inject in the groin is concerning given the known negative consequences associated with the groin as a site of injection. Additionally, PWID who reported drug planting by police were more likely to inject in the groin, suggesting that reliance on law enforcement approaches may undermine safe injection practices in this setting. These findings highlight the need for evidence-based interventions to address the harms associated with groin injecting, including efforts to alert PWID to risks of groin injecting, the distribution of appropriate injecting equipment, and efforts to encourage use of other injecting sites.

Abstract
Clusters of almost 300 cases in time and location might be the result of contamination of specific heroin batches. Since 2000 in the United Kingdom, infections caused by spore-forming bacteria have been associated with increasing illness and death among persons who inject drugs (PWID). To assess temporal and geographic trends in these illnesses (botulism, tetanus, Clostridium novyi infection, and anthrax), we compared rates across England and Scotland for 2000–2009. Overall, 295 infections were reported: 1.45 per 1,000 PWID in England and 4.01 per 1,000 PWID in Scotland. The higher rate in Scotland was mainly attributable to C. novyi infection and anthrax; rates of botulism and tetanus were comparable in both countries. The temporal and geographic clustering of cases of C. novyi and anthrax into outbreaks suggests possible contamination of specific heroin batches; in contrast, the more sporadic nature of tetanus and botulism cases suggests that these spores might more commonly exist in the drug supply or local environment although at varying levels. PWID should be advised about treatment programs, injecting hygiene, risks, and vaccinations.

Abstract
BACKGROUND/AIMS Some patients on opioid maintenance treatment (OMT) leave treatment temporarily or permanently. This study investigated whether patients interrupting their OMT differed from non-interrupters in sociodemographic and drug-use characteristics and examined acute/sub-acute somatic morbidity among the interrupters, prior to, during, and after OMT. METHODS Cohort design. OBSERVATION PERIOD: 5 years prior to, up to first 5 years during, and up to 5 years after interruption of OMT. PARTICIPANTS The sample (n = 200) comprised 51 OMT interrupters and 149 non-interrupters. Data on patient characteristics were obtained from interviews and OMT register information. Data on somatic morbidity were gathered from hospital records. MEASUREMENTS Key patient characteristics among OMT interrupters and non-interrupters. Incidence rates of acute and sub-acute somatic disease incidents leading to hospital treatment (drug-related/non-drug-related/injuries) prior to/during/after OMT. RESULTS Interrupters and non-interrupters did not differ in sociodemographic characteristics, while longer duration of amphetamine and benzodiazepine dependence predicted OMT interruption. Interrupters scored significantly higher on drug-taking and overdose during OMT but still had a significant 41% reduction in drug-related treatment, episodes. After interruption of treatment, such episodes increased markedly and were 3.6 times more frequent during the first post-OMT year compared to the pre-OMT period (p < 0.001). This increase was highest during the first months after OMT interruption. 2-5 years after interruption there was no significant increase. CONCLUSIONS Increased somatic morbidity was found among OMT interrupters during the first year after OMT, and especially during the immediate post-treatment period.

Abstract
Objectives To examine the effect of opioid maintenance treatment (OMT) on somatic morbidity in a cohort of OMT patients. Design Retrospective cohort study. Setting OMT programme in two Norwegian counties. Participants 200 OMT patients, participation rate 71.2%. Main outcome measures Incidence rates (IR) before, during and after OMT for acute/subacute hospital-treated somatic disease incidents (drug-related, non-drug-related, injuries) and rates for inpatient days and outpatient treatment contacts. Results IR for drug-related hospital treatment episodes were 76% lower during compared to before OMT (before versus during incidence rate ratio (IRR) 4.2 (95% CI 2.9 to 6.2), p<0.001) and 11 times higher after compared to during OMT (after versus during IRR 11.1 (6.6 to 18.5), p<0.001). For non-drug-related treatment episodes, IR were 35% higher during than before OMT (before versus during IRR 0.7 (0.6 to 1.0), p=0.02) and 32% higher after compared to during OMT (IRR 1.4 (0.9 to 2.2), p=0.15), while injuries showed little change according to OMT status. Although patients with on-going drug-taking during OMT showed less reduction in drug-related hospital-treated incidents during treatment than patients not using illicit drugs, the quartile with most drug-taking showed a significant reduction (before versus during IRR 3.6 (2.4 to 5.3)). Patients who had experienced cessation of OMT showed a significant reduction in drug-related treatment episodes during OMT (before versus during IRR 1.7 (1.0 to 2.9)), although less than patients without OMT interruptions (before versus during IRR 6.1 (3.6 to 10.6)), and a significant increase after OMT cessation compared with during OMT (IRR 5.4 (3.0 to 9.7)). Conclusion Acute/subacute drug-related somatic morbidity is reduced during compared to before OMT. This was also found for patients with on-going drug-taking during OMT. However, acute drug-related health problems show an increase after OMT cessation, and this is a matter of concern. Further studies on somatic morbidity after OMT cessation should be carried out.
