Trauma patients who test positive for marijuana upon their admission to the intensive care unit are less likely to die during hospitalization than are age-matched controls, according to data published online ahead of print in The Journal of Trauma and Acute Care Surgery.
A team of researchers from the University of Arizona analyzed the in-hospital mortality rates of adults admitted into the ICU over a five-year period, of which 2,678 were matched (1,339: marijuana positive, 1,339 marijuana negative).
Authors concluded: “Patients with a positive marijuana screen had a lower mortality rate (5.3 percent versus 8.9 percent) compared to patients with a negative marijuana screen. … Prospective studies with long-term follow up will be useful in answering many of the remaining questions surrounding the specific impact of marijuana on outcomes after trauma.”
An abstract of the study, “How does marijuana effect outcomes after trauma in ICU patients? A propensity matched analysis,” appears online here.
