Abstract
Background: The societal benefits of substance use interventions are largely driven not by reducing use per se, but by the broader implications of those reductions. This encompasses "potential radiating effects of misusing substances" (PREMiS) such as utilization of high-cost hospital and emergency care, injury, productivity losses, incarceration, and driving while impaired.
Methods: This study is a secondary analysis from a randomized trial comparing in-person vs. computerized brief intervention among 360 adult community health center patients with moderate-risk illicit drug use (N = 302 with complete data through 12 months of follow-up). This study aims to examine four aspects of PREMiS outcomes in this sample: (1) their frequency; and their association with (2) type of brief intervention received (by random assignment), (3) type of drug misused, and (4) baseline drug problem severity (within the moderate risk range).
Results: 12-month prevalence was 18.5% for hospitalization (399 cumulative days), 33.1% for emergency department utilization (166 cumulative visits), 39.1% for injury (1818 injury-days), and 8.3% for incarceration (278 days of detention). There were 729 missed work days among those who reported employment. Fifty percent reported driving under the influence (DUI) of substances. There were no differences in PREMiS outcomes by type of brief intervention. Participants with only marijuana misuse at baseline were not at lower risk of experiencing PREMiS events than participants with other drug misuse. Higher baseline drug problem severity was predictive of future hospitalization (p < .05) and number of hospitalization days (p < .01).
Conclusion: This community health center sample with moderate-risk illicit drug use reported considerable high-cost healthcare utilization, injury, missed work, and DUI. Interventions are needed that can reliably lower risk of negative outcomes among drug users.
