1 · What the graph read from it

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.

2 · The registry

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

backgroundOverdose deaths have increased dramatically in the United States, including in Rhode Island. In July 2021, the Rhode Island government passed legislation supporting a two-year pilot program authorizing supervised consumption sites (SCSs) in response to this crisis. We estimated the costs and benefits of a hypothetical SCS in Providence, Rhode Island.

methodsWe utilized a decision analytic mathematical model to compare costs and outcomes for people who inject drugs under two scenarios: (1) a SCS that includes syringe services provision, and (2) a syringe service program only (i.e., status quo). We assumed 0.95% of injections result in overdose, the SCS would serve 400 clients monthly and have a net cost of $783,899 annually, 46% of overdoses occurring outside of the SCS result in an ambulance run and 43% result in an emergency department (ED) visit, 0.79% of overdoses occurring within the SCS result in an ambulance run and ED visit, and the SCS would lead to a 25.7% reduction in fatal overdoses near the site. The model was developed from a modified societal perspective with a one-year time horizon.

resultsA hypothetical SCS in Providence would prevent approximately 2 overdose deaths, 261 ambulance runs, 244 ED visits, and 117 inpatient hospitalizations for emergency overdose care annually compared to a scenario that includes a syringe service program only. The SCS would save $1,104,454 annually compared to the syringe service program only, accounting only for facility costs and short-term costs of emergency overdose care and ignoring savings associated with averted deaths. Influential parameters included the percentage of injections resulting in overdose, the total annual injections at the SCS, and the percentage of overdoses outside of the SCS that result in an ED visit.

conclusionA SCS in would result in substantial cost savings due to prevention of costly emergency overdose care.
