Client experiences using a new supervised consumption service in Sudbury, Ontario: A qualitative study.

Overdoses are increasing in the province of Ontario, Canada, where northern communities such as Sudbury have witnessed disproportionately elevated rates, with opioid-related deaths double that of the provincial average. To address this issue, governments have implemented supervised consumption services (SCS) where people who use drugs (PWUD) can use their pre-obtained substances onsite under trained supervision. In September 2022, the city of Sudbury opened its first SCS, 'The Spot', but the site's sustainability is contingent on demonstrating benefit to PWUD and the neighboring community. We undertook a qualitative study exploring experiences among clients who used the consumption service inside The Spot. In December 2022, clients of The Spot were invited to participate in a brief survey which collected socio-demographic information and substance use profiles, followed by an in-person semi-structured qualitative interview. Participant survey and interview data were combined with administrative site utilization data provided by site staff of all clients who accessed the consumption service from September 2022 to August 2023 to examine overall service utilization and uptake. Qualitative data were analyzed using iterative thematic analysis techniques, and results were informed by common responses to research questions. The responses were narratively presented. Administrative site utilization data highlighted a relatively stable increase in uptake and utilization of the site since its inception. A total of 20 clients participated in the survey and semi-structured interviews. Participants described the importance of the site in preventing and responding to overdoses, providing a safe and comfortable environment to consume their drugs, and decreasing public drug use, which they suggested may potentially reduce stigmatization in the community. However, clients also suggested challenges, including issues regarding site operational policies that hindered consumption room utilization. Service suggestions made by clients to improve site utilization include the addition of inhalation services, relocating the site to a location in downtown Sudbury where PWUD commonly congregate, and extending operational hours. Positive impacts and recommendations can be drawn on and considered by other northern or rural communities interested in implementing similar harm reduction services.

Considerations for the design of overdose education and naloxone distribution interventions: results of a multi-stakeholder workshop.

INTRODUCTION: Opioid overdose epidemic is a public health crisis that is impacting communities around the world. Overdose education and naloxone distribution programs equip and train lay people to respond in the event of an overdose. We aimed to understand factors to consider for the design of naloxone distribution programs in point-of-care settings from the point of view of community stakeholders. METHODS: We hosted a multi-stakeholder co-design workshop to elicit suggestions for a naloxone distribution program. We recruited people with lived experience of opioid overdose, community representatives, and other stakeholders from family practice, emergency medicine, addictions medicine, and public health to participate in a full-day facilitated co-design discussion wherein large and small group discussions were audio-recorded, transcribed and analysed using thematic approaches. RESULTS: A total of twenty-four participants participated in the multi-stakeholder workshop from five stakeholder groups including geographic and setting diversity. Collaborative dialogue and shared storytelling revealed seven considerations for the design of naloxone distribution programs specific to training needs and the provision of naloxone, these are: recognizing overdose, how much naloxone, impact of stigma, legal risk of responding, position as conventional first aid, friends and family as responders, support to call 911. CONCLUSION: To create an naloxone distribution program in emergency departments, family practice and substance use treatment services, stigma is a central design consideration for training and naloxone kits. Design choices that reference the iconography, type, and form of materials associated with first aid have the potential to satisfy the need to de-stigmatize overdose response.

Design details for overdose education and take-home naloxone kits: Codesign with family medicine, emergency department, addictions medicine and community.

INTRODUCTION: Overdose education and naloxone distribution (OEND) programmes equip and train people who are likely to witness an opioid overdose to respond with effective first aid interventions. Despite OEND expansion across North America, overdose rates are increasing, raising questions about how to improve OEND programmes. We conducted an iterative series of codesign stakeholder workshops to develop a prototype for take-home naloxone (THN)-kit (i.e., two doses of intranasal naloxone and training on how to administer it). METHODS: We recruited people who use opioids, frontline healthcare providers and public health representatives to participate in codesign workshops covering questions related to THN-kit prototypes, training on how to use it, and implementation, including refinement of design artefacts using personas and journey maps. Completed over 9 months, the workshops were audio-recorded and transcribed with visible results of the workshops (i.e., sticky notes, sketches) archived. We used thematic analyses of these materials to identify design requirements for THN-kits and training. RESULTS: We facilitated 13 codesign workshops to identify and address gaps in existing opioid overdose education training and THN-kits and emphasize timely response and stigma in future THN-kit design. Using an iterative process, we created 15 prototypes, 3 candidate prototypes and a final prototype THN-kit from the synthesis of the codesign workshops. CONCLUSION: The final prototype is available for a variety of implementation and evaluation processes. The THN-kit offers an integrated solution combining ultra-brief training animation and physical packaging of nasal naloxone to be distributed in family practice clinics, emergency departments, addiction medicine clinics and community settings. PATIENT OR PUBLIC CONTRIBUTION: The codesign process was deliberately structured to involve community members (the public), with multiple opportunities for public contribution. In addition, patient/public participation was a principle for the management and structuring of the research team.

Service utilization patterns and characteristics among clients of integrated supervised consumption sites in Toronto, Canada.

INTRODUCTION: Supervised consumption services (SCS), intended to reduce morbidity and mortality among people who inject drugs, have been implemented in a variety of delivery models. We describe and compare access to and uptake of co-located and external services among clients accessing harm reduction-embedded (HR-embedded) and community health center-embedded (CHC-embedded) SCS models. METHODS: Cross-sectional baseline data were collected between November 2018 and March 2020 as part of a cohort of people who inject drugs in Toronto, Canada designed to evaluate one HR-embedded and two CHC-embedded SCS. This analysis was restricted to clients who reported accessing these SCS more than once in the previous 6 months. Participants were classified as HR-embedded or CHC-embedded SCS clients based on self-reported usage patterns. Client characteristics, as well as access to onsite services and referral and uptake of external services, were compared by SCS model. RESULTS: Among 469 SCS clients, 305 (65.0%) primarily used HR-embedded SCS and 164 (35.0%) primarily used CHC-embedded SCS. Compared to clients accessing CHC-embedded SCS, clients accessing HR-embedded SCS were somewhat younger (37.6 vs. 41.4, p < 0.001), more likely to report fentanyl as their primary injected drug (62.6% vs. 42.7%, p < 0.001), and visited SCS more often (49.5% vs. 25.6% ≥ daily, p < 0.001). HR-embedded SCS clients were more likely to access harm reduction services onsite compared to CHC-embedded SCS clients (94.8% vs. 89.6%, p = 0.04), while CHC-embedded SCS clients were more likely to access non-harm reduction services onsite (57.3% vs. 26.6%, p < 0.001). For external services, HR-embedded SCS clients were more likely to receive a referral (p = 0.03) but less likely to report referral uptake (p = 0.009). CONCLUSIONS: Clients accessing HR-embedded and CHC-embedded SCS were largely demographically similar but had different drug and SCS use patterns, with CHC-embedded SCS clients using the site less frequently. While clients of CHC-embedded SCS reported greater access to ancillary health services onsite, external service use remained moderate overall, underscoring the importance of co-location and support for clients with system navigation. Importantly, lack of capacity in services across the system may impact ability of staff to make referrals and/or the ability of clients to take up a referral.

Diverse psychotropic substances detected in drug and drug administration equipment samples submitted to drug checking services in Toronto, Ontario, Canada, October 2019-April 2020.

BACKGROUND: The overdose crisis has generated innovative harm reduction and drug market monitoring strategies. In Toronto, Ontario, Canada, a multi-site drug checking service (DCS) pilot project was launched in October 2019. The project provides people who use drugs with information on the chemical composition of their substances, thereby increasing their capacity to make more informed decisions about their drug use and avoid overdose. DCS also provides real-time market monitoring to identify trends in the unregulated drug supply. METHODS: Sample data were obtained through analyses of drug and used drug administration equipment samples submitted anonymously and free of charge to DCS in downtown Toronto from October 10, 2019, to April 9, 2020, representing the first six months of DCS implementation. Analyses were conducted in clinical laboratories using liquid chromatography- and/or gas chromatography-mass spectrometry (LC-MS, GC-MS) techniques. RESULTS: Overall, 555 samples were submitted, with 49% (271) of samples that were found to contain high-potency opioids, of which 87% (235) also contained stimulants. Benzodiazepine-type drugs were found in 21% (116) of all samples, and synthetic cannabinoids in 1% (7) of all samples. Negative effects (including overdose, adverse health events, and extreme sedation) were reported for 11% (59) of samples submitted for analysis. CONCLUSIONS: Toronto's DCS identified a range of high-potency opioids with stimulants, benzodiazepine-type drugs, and a synthetic cannabinoid, AMB-FUBINACA. This information can inform a range of evidence-informed overdose prevention efforts.

Mixed methods feasibility study for the surviving opioid overdose with naloxone education and resuscitation (SOONER) trial.

AIM: We plan to conduct a randomised clinical trial among people likely to witness opioid overdose to compare the educational effectiveness of point-of-care naloxone distribution with best-available care, by observing participants' resuscitation skills in a simulated overdose. This mixed methods feasibility study aims to assess the effectiveness of recruitment and retention strategies and acceptability of study procedures. METHODS: We implemented candidate-driven recruitment strategies with verbal consent and destigmatizing study materials in a family practice, emergency department, and addictions service. People ≥16 years of age who are likely to witness overdose were randomized to point-of-care naloxone distribution or referral to an existing program. We evaluated participant skills as a responder to a simulated overdose 3-14 days post-recruitment. Retention strategies included flexible scheduling, reminders, cash compensation and refreshments. The primary outcome was recruitment and retention feasibility, defined as the ability to recruit 28 eligible participants in 28 days, with <50% attrition at the outcome simulation. Acceptability of study procedures and motivations for participation were assessed in a semi-structured interview. RESULTS: We enrolled 30 participants over 24 days, and retained 21 participants (70%, 95%CI 56.7-100). The most common motivation for participation was a desire to serve the community or loved ones in distress. Participants reported that study procedures were acceptable and that the outcome simulation provided a supportive and affirming environment. CONCLUSION: The planned trial is ready for implementation. Recruitment and retention is feasible and study processes are acceptable for people who are likely to witness overdose. (Registration: NCT03821649).

Supervised consumption service use and recent non-fatal overdose among people who inject drugs in Toronto, Canada.

BACKGROUND: Aiming to reducing overdose mortality, over 40 supervised drug consumption services (SCS) presently operate in Canada. Arguments against SCS include the potential for increased non-fatal overdoses mediated by risk compensation. This study estimates associations between SCS use and recent non-fatal overdose among people who inject drugs (PWID). METHODS: We analyzed cross-sectional baseline data collected between November 2018 and March 2020 from a cohort of adult PWID in Toronto, Canada. Recent non-fatal overdose was self-reported over the previous six months. The primary exposure was frequency of SCS use, self-reported as the proportion of injections performed at an SCS (all or most [75-100%], some [26-74%], few [≤25%], or none) in the previous six months. The prevalence of recent overdose was compared between all unique pairs of groups based on their frequency of SCS use and expressed as covariate-adjusted prevalence ratios (PR) estimated using modified Poisson regression. RESULTS: Among 701 PWID (median [IQR] age, 40 [33 to 49]; 64.3% cisgender men; 56.8% injecting daily), most reported SCS use (all/most, 26.2%; some, 30.9%; few, 29.4%) versus no use (13.5%), with 38.6% reporting a recent overdose. From adjusted regression analyses, more frequent SCS use was not statistically significantly associated with overdose when compared to either no SCS use or less frequent use. Associations between SCS use frequency and overdose were notably smaller among SCS clients compared to associations between SCS clients and non-users (e.g., all/most versus none: PR, 1.43 [95% CI, 0.93 to 2.21]; all/most versus some: PR, 0.94 [95% CI, 0.75 to 1.17]; all/most versus few: PR, 1.15 [95% CI, 0.89 to 1.48]). CONCLUSION: Findings did not indicate statistically significant associations between SCS use frequency and recent non-fatal overdose, particularly among SCS clients who may be more comparable. Nevertheless, overdose was common, underscoring the need to prevent non-fatal overdose and associated morbidity.

Challenges, Skepticism, and Recommendations from Police about Working in Collaboration with Supervised Consumption Services.

BACKGROUND: The operation of supervised consumption services (SCS), programs that offer supervised locations for the consumption of drugs such as heroin, other opioids, cocaine, other stimulants, and other drugs, is contingent on cooperative relationships with police. In this manuscript, we focus on an under studied topic: how active duty police officers understand their role with respect to SCS, and their recommendations for improving relationships with these programs. Methods: During 2018, we audio-recorded and transcribed focus group discussions conducted in four police divisions with 26 police constables and 3 officers of other ranks in Toronto, Canada. Officers were asked about their roles relative to SCS, perceived training needs, and how to build cooperative relationships with SCS. We followed an iterative thematic approach to analyze the data. Results: Participants in three divisions were unclear about their roles, duties, and policy governing policing of SCS. Participants in the fourth division had received instructions from the division commander to observe a "distance and discretion policy". However, these participants believed that developing familiarity with the new SCS, instead of keeping a distance, would be a more effective approach to building working relationships with staff, clients, and the local community. There was nearly unanimous skepticism about the willingness of SCS workers to work cooperatively with the police. These perceptions were commonly linked to previous negative experiences with harm reduction workers and, in some cases, staff at the new SCS. Several participants also linked problems in communication to fundamental differences between the philosophies or worldviews of SCS staff versus those of police. Conclusions: Building collaborative SIS-police relationships can be assisted by demystifying the operation of SCS for police, articulating policies, and working toward mutual respect.

Protocol for a mixed-methods feasibility study for the surviving opioid overdose with naloxone education and resuscitation (SOONER) randomised control trial.

INTRODUCTION: The surviving opioid overdose with naloxone education and resuscitation (SOONER) project uses co-design and trial methods to develop and evaluate a point-of-care overdose education and naloxone distribution (OEND) tool. We plan to conduct a randomised controlled trial to assess the effectiveness of our OEND tool in comparison with best available standard of care by observing participants' performance as a responder to a simulated overdose. Recruiting and retaining people at risk of or likely to witness opioid overdose raises scientific, logistical and bioethical challenges. A feasibility study is needed to establish the effectiveness of recruitment and retention strategies and acceptability of study procedures prior to launching the full trial. METHODS AND ANALYSIS: Strategies to enhance recruitment include candidate-driven recruitment, verbal informed consent, and attractive, destigmatising materials. Adults at risk of or likely to witness opioid overdose will be recruited through an urban emergency department, inpatient and ambulatory addiction medicine service, and outpatient family practice settings. Participants randomised to the intervention arm will receive our OEND intervention; those in the control arm will be referred to existing OEND programme. Retention procedures include participant reminders, flexible scheduling, cash and comfort compensation, and strategies to maintain a consistent relationship between individual study staff and participants. Within 2 weeks following recruitment, participants will engage as a responder to a manikin-simulated overdose, and complete overdose knowledge and attitudes questionnaires. The primary outcome is recruitment and retention feasibility, defined as the recruitment of 28 participants within 28 days of recruitment and <50% attrition at the overdose simulation. Staff and participant feedback will also be collected and considered. ETHICS AND DISSEMINATION: The study has been reviewed by ethics boards at St. Michael's Hospital, Toronto Public Health and the University of Toronto. Dissemination will occur through peer-reviewed publication and presentations. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov registry (NCT03821649).

Creating and sustaining cooperative relationships between supervised injection services and police: A qualitative interview study of international stakeholders.

BACKGROUND: Supervised injection services (SIS) operate with special exemptions from drug law enforcement. Given the expansion of SIS and the opioid overdose crisis in numerous jurisdictions, now is a critical time to examine factors that contribute to cooperative SIS-police relationships. We sought to learn about SIS-police relationships from international jurisdictions with well-established as well as newer SIS. METHODS: We conducted 16 semi-structured telephone interviews with SIS managers (n = 10) and police liaisons (n = 6) from 10 cities in seven different countries (Australia, Canada, Denmark, France, Germany, Netherlands, and Spain). All participants provided informed consent. We focused our coding and analysis on themes that emerged from the data. RESULTS: Five key contributors to cooperative SIS-police relationships emerged from the data: early engagement and dialogues; supportive police chiefs; dedicated police liaisons; negotiated boundary agreements; and regular face-to-face contact. Most participants perceived the less formalised, on-the-ground approach to relationship-building between police and SIS adopted in their city to be working well in general. SIS managers and police participants reported a lack of formal police training on harm reduction, and some thought that training was unnecessary given the relatively positive local SIS-police relationships they reported. CONCLUSION: Our qualitative study provides new, in-depth empirical examples of how police in varied international jurisdictions can come to accept and work cooperatively with, not against, SIS staff and clients. Investing ongoing effort in SIS-police relationships, in a manner that best suits local needs, may hold greater and more sustainable public health value than delivering specific curricula to police.

Process evaluation of the Prevent Overdose in Toronto (POINT) program.

SETTING: A harm reduction program at a public health unit in Toronto, Ontario, between August 31, 2011 and August 31, 2013. INTERVENTION: We conducted a process evaluation of the first two years of an opioid overdose prevention and response program, Prevent Overdose in Toronto (POINT), including analysis of data from program documentation forms, as well as qualitative interviews with program staff, representatives from partner agencies, and program clients. OUTCOMES: In the first two years of the program, 662 individuals (52.4% male; mean age 38.3 years) were trained in opioid overdose prevention and given a naloxone kit. Among clients currently using opioids, the most frequently reported opioids were oxycodone (40.4%) and heroin (34.4%). Clients reported 98 administrations of naloxone, primarily to friends and acquaintances. Nearly all naloxone recipients reportedly survived; one did not survive, and one had an unknown outcome.Staff and partner agencies feel the program reaches the target population and that POINT training meets clients' needs. Clients would like to see the training offered more widely. Overall, staff, partner agencies and clients were pleased with the POINT program, and they offered suggestions on program recruitment and delivery. IMPLICATIONS: Individuals at risk of opioid overdose have participated in overdose prevention and response training, and reported using naloxone in overdose events. Results of this initial program evaluation are being used to improve the delivery of the POINT program and can inform broader public health practice in opioid overdose prevention.

Development and implementation of an opioid overdose prevention and response program in Toronto, Ontario.

OBJECTIVES: We describe the development of the first community-based opioid overdose prevention and response program with naloxone distribution offered by a public health unit in Canada (Prevent Overdose in Toronto, POINT). PARTICIPANTS: The target population is people who use opioids by any route, throughout the City of Toronto. SETTING: The POINT program is operated by the needle exchange program at Toronto Public Health (The Works) and offered at over 40 partner agency sites throughout Toronto. INTERVENTION: POINT is a comprehensive program of overdose prevention and response training, including naloxone dispensing. Clients are instructed by public health staff on overdose risk factors, recognizing signs and symptoms of overdose, calling 911, naloxone administration, stimulation and chest compressions, and post-overdose care. Training is offered to clients one-on-one or in small groups. Clients receive a naloxone kit including two 1 mL ampoules of naloxone hydrochloride (0.4 mg/mL) and are advised to return to The Works for a refill and debriefing if the naloxone kit is used. OUTCOMES: In the first 8 months of the program, 209 clients were trained. Clients have reported 17 administrations of naloxone, and all overdose victims have reportedly survived. Client demand for POINT training has been high, and Toronto Public Health has expanded its capacity to provide training. Overall, reception to the program has been overwhelmingly positive. CONCLUSION: We are encouraged by the initial development and implementation experience with the naloxone program and its potential to save lives in Toronto. We have planned short-, intermediate-, and long-term process and outcome evaluations.

What is low threshold methadone maintenance treatment?

BACKGROUND: Low threshold methadone maintenance (MMT) was developed for clients who do not have abstinence as a treatment goal. We explored how MMT programs in Canada defined low threshold and the challenges they faced. METHODS: Using semi-structured interviews, we collected data from clients (n=46), nurses/counsellors (n=15) and physicians (n=9) at three low threshold MMT programs. All participants were asked to define low threshold MMT and describe how it was implemented in practice. Interviews were taped, transcribed, verified and analysed using an iterative thematic coding technique. RESULTS: Low threshold MMT was defined by an explicit rejection of abstinence from opiates and other drugs as an over-arching treatment goal. In the absence of guidelines defining a set of practices as low threshold, programs implemented practices they believed would reduce barriers to admission and help retention. There was not always agreement between professional groups or across the programs regarding these practices. For physicians, there was a tension between accepting poly-drug use during treatment as a means to improve retention, with an obligation to do more good than harm for their patients. Missed prescribing appointments generated few to severe consequences and revealed differential focus on reducing barriers versus encouraging client 'ownership' of treatment. Differences of opinion regarding appropriate urine drug testing practices revealed power dynamics between medical and non-medical staff. CONCLUSION: Our findings show that there are potentially more ways to reduce barriers to MMT than those presented in the current literature. Our findings are important given the growing number of people with opiate dependence across the world and calls to increase access to MMT. To fully develop the low threshold model, it will be important to evaluate what policies and practices can achieve the goals of reducing barriers to admission and improving retention in treatment.

Design considerations for supervised consumption facilities (SCFs): preferences for facilities where people can inject and smoke drugs.

BACKGROUND: Supervised consumption facilities (SCFs) aim to improve the health and well-being of people who use drugs by offering safer and more hygienic alternatives to the risk environments where people typically use drugs in the community. People who smoke crack cocaine may be willing to use supervised smoking facilities (SSFs), but their facility design preferences and the views of other stakeholders have not been previously investigated in detail. METHODS: We consulted with people who use drugs and other stakeholders including police, fire and ambulance service personnel, other city employees and city officials, healthcare providers, residents, and business owners (N = 236) in two Canadian cities without SCFs and asked how facilities ought to be designed. All consultations were audio-recorded and transcribed. Thematic analyses were used to describe the knowledge and opinions of stakeholders. RESULTS: People who use drugs see SSFs as offering public health and safety benefits, while other stakeholders were more sceptical about the need for SSFs. People who use drugs provided insights into how a facility might be designed to accommodate supervised injection and supervised smoking. Their strongest preference would allow both methods of drug use within the same facility with some form of physical separation between the two based on different highs, comfort regarding exposure to different methods of drug administration, and concerns about behaviours often associated with smoking crack cocaine. Other stakeholders raised a number of SSF implementation challenges worthy of consideration. CONCLUSION: Decision-makers in cities considering SCF or SSF implementation should consider the opinions and preferences of potential clients to ensure that facilities will attract, retain, and engage people who use drugs.

Reducing widespread pipe sharing and risky sex among crystal methamphetamine smokers in Toronto: do safer smoking kits have a potential role to play?

BACKGROUND: Crystal methamphetamine smoking is associated with many negative health consequences, including the potential for transmission of hepatitis. We examined whether or not a kit for crystal methamphetamine smoking might have some potential to reduce the negative health effects of crystal methamphetamine smoking. METHODS: Five focus groups were conducted with crystal methamphetamine smokers recruited by community health agencies and youth shelters in Toronto, Canada. Target groups included homeless/street-involved youth, sex workers, men who have sex with men, and youth in the party scene. Participants (n = 32) were asked questions about motivations for crystal methamphetamine use, the process of smoking, health problems experienced, sharing behaviour, risky sexual practices, and the ideal contents of a harm reduction kit. RESULTS: Pipe sharing was widespread among participants and was deemed integral to the social experience of smoking crystal methamphetamine. Heated pipes were unlikely to cause direct injuries, but participants mentioned having dry, cracked lips, which may be a vector for disease transmission. Many reported having sex with multiple partners and being less likely to use condoms while on the drug. Demand for harm reduction kits was mixed. CONCLUSIONS: Changing pipe sharing behaviours may be difficult because many participants considered sharing to be integral to the social experience of smoking crystal methamphetamine. Within the context of a broader health promotion and prevention program, pilot testing of safer smoking kits to initiate discussion and education on the risks associated with sharing pipes and unprotected sex for some communities (e.g., homeless/street-involved youth) is worth pursuing.

Guidelines for better harm reduction: evaluating implementation of best practice recommendations for needle and syringe programs (NSPs).

BACKGROUND: The objective of this study was to evaluate needle and syringe program (NSP) policies and procedures before and after the dissemination of a set of best practice recommendations. METHODS: An on-line survey of 32 core NSP managers (100% response rate) and 62 satellite NSP managers (63% response rate). The survey included items about the distribution of needles/syringes, other injection-related equipment and inhalation equipment, and use of a best practice recommendations document. RESULTS: The majority of NSPs reported following needle and syringe best practice recommendations. Most core NSPs (88%, n=28) and satellite NSPs (84%, n=52) distributed cookers following the dissemination of the document. All core NSPs (100%, n=32) and nearly all satellite NSPs (97%, n=60) distributed sterile water ampoules in 2008, many more than in 2006. Although more NSPs distributed safer inhalation equipment in 2008, the majority did not distribute these items. More satellite NSPs (44%, n=27) distributed glass stems than the core NSPs (16%, n=5). Commonly cited implementation barriers included funding, senior management and decision-making. CONCLUSION: Our findings demonstrate that NSPs will implement empirically based best practice recommendations and welcome such guidance. The managers we surveyed not only reported increased implementation of practices that have been empirically shown to help reduce disease transmission among injection drug users (IDUs), they also used the best practices document for additional purposes, such as planning and advocacy, and expressed interest in having sets of recommendations developed for other areas of harm reduction. Ensuring high-quality and consistent NSP services is essential to prevent transmission of HIV among people who inject drugs and others in the community. Best practice recommendations can assist in achieving these goals.

No effect of carbohydrate feeding on 16 km cycling time trial performance.

The aim of this study is to investigate the effects of CHO ingestion during high intensity exercise performance lasting approximately 25 min. Twelve endurance trained male cyclists (age 19-41 years; body mass 73.2 +/- 4.2 kg; VO(2)max 66.4 +/- 6.2 ml kg(-1) min(-1)) completed a simulated 16 km time trial (457 +/- 37 kJ) time trial in the lab on three occasions. Once they received a 6% carbohydrate electrolyte solution (CHO) and twice they received the same electrolyte containing placebo drink (PLA). Carbohydrate or placebo drinks were ingested 5 min before the start (4 ml kg(-1)) and at 25, 50, and 75% of completion of the time trial (1.4 ml kg(-1)). The CHO drink was a 6% sucrose-glucose-electrolyte solution. No differences were observed in the time to complete the time trials with either treatment. Time in min:s were 25:30 +/- 1:34 and 25:27 +/- 1:46 for the two placebo trials and 25:38 +/- 1:59 in the CHO trial. Power output during the time trials was also remarkably similar: 300 +/- 37 W, 301 +/- 39 W and 299 +/- 40 W, respectively. Pacing strategies and heart rate were identical in all three trials. From the two placebo trials, a coefficient of variation for this performance task was calculated to be 1.1%. Data from this study provides evidence that carbohydrate ingestion during short high intensity exercise (approximately 30 min, 85-90% VO(2)max) does not improve performance. Furthermore, this study found a very low coefficient of variation (1.1%) for a simulated 16 km time trial.

Reduction in injection-related HIV risk after 6 months in a low-threshold methadone treatment program.

This study assessed injection-related HIV risk behavioral changes among opioid users 6 months after enrollment in low-threshold (harm reduction based) metha-done maintenance treatment (MMT) programs within needle exchange services in Kingston and Toronto, Ontario, Canada. Changes were assessed for all participants (whole cohort), participants who continued to use illicit drugs by any route (drug-using subcohort); and those who continued to inject drugs (injecting subcohort). In this prospective observational cohort study, an interviewer-administered questionnaire examining injection-related HIV risk behaviors was administered to 183 study participants at entry to treatment and 6 months later. Changes in risk behaviors were analyzed using conditional logistic regression which took into account the paired nature of the data. We found that the proportion of participants injecting drugs, sharing needles, sharing drug equipment, indirectly sharing and using shooting galleries declined with follow-up for the whole cohort. Within the drug-using subcohort, there was a decrease in the proportion of individuals who injected drugs, while within the injecting subcohort the sharing of injection equipment and the use of shooting galleries declined. Our findings suggest that low-threshold MMT programs can reduce the risk of HIV without the enforcement of abstinence-based policies.

Determinants of health-related quality of life of opiate users at entry to low-threshold methadone programs.

OBJECTIVE: The aim of this study was to conduct an exploratory analysis of factors associated with poor health-related quality of life (HRQOL) among opiate users at entry to low-threshold methadone treatment. METHODS: The SF-36 questionnaire was administered to 145 opiate users at enrollment into low-threshold methadone maintenance programs. ANOVA and correlational analyses were performed to investigate the determinants of poor physical and mental composite summary scales (PCS and MCS) of the SF-36 among opiate users. Stepwise regression methods were also employed to fit PCS and MCS multivariate models. RESULTS: Age, employment status, chronic medical conditions, hospitalization, emotional abuse, sexual abuse and age at first injection episode were significantly associated with PCS. Mental health problems, sexual abuse, physical abuse, the use of sedatives, the use of cocaine, the number of days of cocaine use, sedative use and multiple substance use in the past month were significantly associated with MCS. The variances in the MCS and PCS were not readily explained by any one factor. CONCLUSION: The multiplicity of factors influencing HRQOL of opiate users suggests the need for a range of services within the context of a methadone program, addressing primary medical care needs as well as treatment for both mental health problems and abuse issues.
