What is the risk of returning to the emergency department within 30 days for patients diagnosed with substance-induced psychosis?
Article in CJEM, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectivesThe primary objective of this study was to measure the risk of return Emergency Department (ED) visits in patients presenting to the ED with a diagnosis of substance-induced psychosis. Secondary objectives included: (1) describing the characteristics of patients returning within 30 days to the ED with substance-induced psychosis, and (2) identifying risk factors associated with such ED return.
methodsAt two urban sites from January 1, 2018 to December 31, 2019, we included consecutive patients presenting to the ED with substance-induced psychosis defined by their ED discharge diagnosis of psychosis and clinical evidence of substance use. We described ED resources utilized by this patient population including ED time and disposition then subsequently described return visits within 30 days and characteristics among those patients who returned.
resultsWe identified 611 unique patients presenting with substance-induced psychosis, with 813 total ED visits. The median age was 35 years (IQR 28-45), 71.4% (n = 436) were male, and 44.8% (n = 274) were homeless. The median ED length of stay was 619 min (IQR 313-898), and 48.4% (n = 296) were admitted to hospital. Forty percent of patients (n = 237) returned to the ED within 30 days of the index substance-induced psychosis visit, 116 (18.9%) returning more than once. Of these return visits, 74 (31.2%) were for recurrent substance-induced psychosis. Younger age, female gender, no opioid use, and no prior history of bipolar disorder were identified as common characteristics among those returning to the ED with substance-induced psychosis.
conclusionsIn ED patients with substance-induced psychosis, nearly half of all patients were admitted to hospital, 40% had a 30 days return ED visit, and one-third of those were for substance-induced psychosis. We identified clinically relevant factors common to those returning with recurrent substance-induced psychosis.
