Psychiatric Medication Treatment, Concurrent Substance Use, and Subsistence Difficulty Among People Who Inject Drugs with Diagnosed Mental Health Disorders in Los Angeles and Denver.

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
backgroundLimited literature exists on how concurrent substance use and difficulty meeting basic needs impact recent psychiatric treatment among people who inject drugs (PWID) with diagnosed mental health disorders in the U.S. This study assessed the prevalence of taking current psychiatric medication treatment, and its association with concurrent substance use and subsistence difficulty.
methodBaseline data from a prospective cohort study in Los Angeles, CA and Denver, CO between April 2021 and November 2022 were analyzed. Modified Poisson regression assessed the association between demographics, concurrent substance use, subsistence difficulty, and recent psychiatric medication treatment.
resultsOut of 429 PWID, 287 (66.9%) who reported a history of diagnosed mental health disorders were included. Among them, 86.8% of participants were unhoused or unstably housed, and 22.6% reported taking prescribed psychiatric medications in the past three months. Factors positively associated with current psychiatric medication treatment included older age (40-59: adjusted prevalence ratio [aPR] = 1.84, 95%CI: 1.15, 2.94); 60-76: aPR = 2.22, 95%CI: 1.21, 4.06; vs. 20-39 years old), non-medical prescription opioid use (aPR = 1.57, 95%CI: 1.06, 2.35), and recent overdose (aPR = 2.16, 95%CI: 1.45, 3.22). Conversely, being unhoused or unstably housed (aPR = 0.51, 95%CI: 0.29, 0.89) and high subsistence difficulty (aPR = 0.41, 95%CI: 0.21, 0.81) were less likely to take prescribed psychiatric medications.
conclusionA significant gap exists in psychiatric medication treatment among PWID with diagnosed mental health disorders. Integrated treatment programs addressing essential needs, such as food and clothing, alongside overdose prevention and mental health care, are urgently needed, particularly for those struggling with substance use and housing instability.
