Exploration of novel harm reduction approaches to increase client engagement (ENHANCE): protocol for a prospective cohort study.
Article in Harm reduction journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundSyringe services programs (SSPs) reduce the risk of overdose by distributing supplies like naloxone. SSPs also support clients in meeting their basic needs via referrals to organizations providing food, housing, and healthcare. This paper describes the Exploration of Novel Harm Reduction Approaches to Increase Client Engagement (ENHANCE) Project, a prospective cohort study developed in partnership with people who use drugs that aims to characterize the influence of longitudinal engagement in SSPs on overdose risk behaviors.
methodsThe ENHANCE Project protocol was developed with a community leadership team of 16 people with living experience of drug use who were clients from four SSPs in Wisconsin that serve as study recruitment sites. The community leadership team met five times to conceptualize the study priorities, protocol, recruitment strategies, and measures. ENHANCE will enroll 400 people who use opioids and/or stimulants via recruitment of clients from study sites and peer referrals. Clients will report on primary outcomes (overdose experiences and risk behaviors) and other covariates (substance use history and behaviors, mental and physical health, satisfaction of basic needs, stigma, and others) over a 2-year follow-up period. At enrollment, clients select a self-generated identification code that is documented in all subsequent harm reduction services received from ten SSPs in Wisconsin. These data will be linked to study survey data using probabilistic methods and used for the primary exposure variable, frequency of using SSP services. ENHANCE will test the primary hypothesis that more frequently using SSP services is associated with reduced overdose risk behavior frequency. PRELIMINARY
resultsAmong the first 125 clients enrolled, 22.4% (N = 28) reported personally experiencing an opioid overdose in the 6 months before enrollment and 38.4% (N = 48) experienced adverse effects after using stimulants. The most common overdose risk behaviors reported in the past 30 days were using opioids while alone (mean: 9.9 days [standard deviation: 10.7]) and injecting heroin (mean: 9.3 days [standard deviation: 12.8]).
conclusionsThis study will identify aspects of harm reduction services that are most effective in reducing overdose risk to inform future service provision, funding, and policy efforts.
