Twenty-one years at the Uniting Medically Supervised Injecting Centre, Sydney: addressing the remaining questions

Changes in Australians' attitudes towards supervised injecting facilities

INTRODUCTION

Supervised injecting facilities (SIF) have been shown to reduce negative outcomes experienced by people who inject drugs. They are often subject to intense public and media scrutiny. This article aimed to explore population attitudes to SIFs and how these changed over time in Australia.

METHODS

Data were drawn from the National Drug Strategy Household Survey, a national sample collecting data on illicit drug use and attitudes towards drug policy among Australians (2001-2019). Ordinal logistic regression assessed sociodemographic characteristics associated with different attitudes to SIFs and binary logistic regression assessed trends over time and by jurisdiction.

RESULTS

In 2019, 54% of respondents (95% CI 52.9, 55.1) supported SIFs, 27.5% (95% CI 26.6, 28.4) opposed and 18.4% (95% CI 17.7, 19.2) were ambivalent. Support for SIFs correlated with having a university degree (OR 1.75; 95% CI 1.58, 1.94), non-heterosexual identity (OR 1.81, 95% CI 1.51, 2.17) and recent illicit drug use (OR = 1.74, 95% CI 1.55, 1.94). Male respondents or those living in socioeconomically disadvantaged areas had lower odds of supporting SIFs (OR 0.92, 95% CI 0.85, 1.00; OR 0.64-0.80, respectively). Between 2001 and 2019, support for SIFs increased modestly by 3.3%, those who 'don't know' by 7.4%, whereas opposition decreased by 11.7%. Between 2001 and 2019, support for SIFs increased in NSW and Queensland, whereas opposition decreased in all jurisdictions.

DISCUSSION AND CONCLUSIONS

Opposition to SIFs declined over the past 20 years, but a substantial proportion of respondents are ambivalent or 'don't know enough to say'. Plain language information about SIFs and their potential benefits, targeted to those who are ambivalent/'don't know' may further increase public support.

Overdose prevention centres as spaces of safety, trust and inclusion: A causal pathway based on a realist review

ISSUES

Overdose prevention centres (OPC) are non-residential spaces where people can use illicit drugs (that they have obtained elsewhere) in the presence of staff who can intervene to prevent and manage any overdoses that occur. Many reviews of OPCs exist but they do not explain how OPCs work.

APPROACH

We carried out a realist review, using the RAMESES reporting standards. We systematically searched for and then thematically analysed 391 documents that provide information on the contexts, mechanisms and outcomes of OPCs.

KEY FINDINGS

Our retroductive analysis identified a causal pathway that highlights the feeling of safety - and the immediate outcome of not dying - as conditions of possibility for the people who use OPCs to build trust and experience social inclusion. The combination of safety, trust and social inclusion that is triggered by OPCs can - depending on the contexts in which they operate - generate other positive outcomes, which may include less risky drug use practices, reductions in blood borne viruses and injection-related infections and wounds, and access to housing. These outcomes are contingent on relevant contexts, including political and legal environments, which differ for women and people from racialised minorities.

CONCLUSIONS

OPCs can enable people who live with structural violence and vulnerability to develop feelings of safety and trust that help them stay alive and to build longer term trajectories of social inclusion, with potential to improve other aspects of their health and living conditions.

Epidemiology of Hepatitis C infection in pregnancy: Patterns and trends in West Virginia using statewide surveillance data

BACKGROUND

The increasing rate of Hepatitis C virus (HCV) infection has been attributed to the substance use epidemic. There is limited data on the current rates of the paralleling HCV epidemic.

OBJECTIVES

To estimate the prevalence of maternal HCV infection in West Virginia (WV) and identify contributing factors.

METHODS

Population-based retrospective cohort study of all pregnant individual(s) who gave birth in WV between 01/01/2020 to 01/30/2024 (N = 69,925). Multiple log-binomial regression models were used to estimate the adjusted risk ratio (ARR) and the 95% confidence intervals (CI).

RESULTS

The rate of maternal HCV infection was 38 per 1,000 deliveries. The mean age of pregnant individual(s) with HCV was 29.99 (SD 4.95). The risk of HCV was significantly higher in White vs. minority racial groups [ARR 1.93 (1.50, 2.49)], those with less than [ARR 1.57 (1.37, 1.79)] or at least high school [ARR 1.31 (1.17, 1.47)] vs. more than high school education, those on Medicaid [ARR 2.32 (1.99, 2.71)] vs. private health insurance, those residing in small-metro [ARR 1.32 (1.17, 1.48)] and medium-metro [ARR 1.41 (1.24, 1.61)], vs. rural areas, and those who smoked [ARR 3.51 (3.10, 3.97)]. HCV risk was highest for those using opioids [ARR 4.43 (3.95, 4.96)]; followed by stimulant use [ARR = 1.79 (1.57, 2.04)].

CONCLUSIONS

Our findings highlight that maternal age, race, education, and type of health insurance are associated with maternal HCV infection. The magnitude of association was highest for pregnant individual(s) who smoked and used opioids and stimulants during pregnancy in WV.

Overdose mortality incidence and supervised consumption services in Toronto, Canada: an ecological study and spatial analysis

BACKGROUND

Supervised consumption services (SCS) prevent overdose deaths onsite; however, less is known about their effect on population-level overdose mortality. We aimed to characterise overdose mortality in Toronto, ON, Canada, and to establish the spatial association between SCS locations and overdose mortality events.

METHODS

For this ecological study and spatial analysis, we compared crude overdose mortality rates before and after the implementation of nine SCS in Toronto in 2017. Data were obtained from the Office of the Chief Coroner of Ontario on cases of accidental death within the City of Toronto for which the cause of death involved the use of an opiate, synthetic or semi-synthetic opioid, or other psychoactive substance. We assessed overdose incident data for global spatial autocorrelation and local clustering, then used geographically weighted regression to model the association between SCS proximity and overdose mortality incidence in 2018 and 2019.

FINDINGS

We included 787 overdose mortality events in Toronto between May 1, 2017, and Dec 31, 2019. The overdose mortality rate decreased significantly in neighbourhoods that implemented SCS (8·10 deaths per 100 000 people for May 1-July 31, 2017, vs 2·70 deaths per 100 000 people for May 1-July 31, 2019; p=0·037), but not in other neighbourhoods. In a geographically weighted regression analysis that adjusted for the availability of substance-use-related services and overdose-related sociodemographic factors by neighbourhood, the strongest local regression coefficients of the association between SCS and overdose mortality location ranged from -0·60 to -0·64 per mile in 2018 and from -1·68 to -1·96 per mile in 2019, suggesting an inverse association.

INTERPRETATION

We found that the period during which SCS were implemented in Toronto was associated with a reduced overdose mortality in surrounding neighbourhoods. The magnitude of this inverse association increased from 2018 to 2019, equalling approximately two overdose fatalities per 100 000 people averted in the square mile surrounding SCS in 2019. Policy makers should consider implementing and sustaining SCS across neighbourhoods where overdose mortality is high.
