Association between the detection of alcohol, illicit drugs and/or psychotropic medications/ opioids in patients admitted due to trauma and trauma recidivism: A cohort study

Abstract

To quantify the association between the presence and type of drug detected and trauma recidivism in a cohort of patients admitted due to trauma. The incidence rate of TR was 10.94 cases per 100 patient-years in the group of patients negative for substances and 27.99 per 100 patient-years in positive patients. The survival curves show very significant differences in cumulative recurrence-free survival between the groups (Log Rank: p<0.001). Both the aHRR and the aIRR estimates show an increased risk of re-injury due to alcohol consumption (aIRR: 2.33 (1.72±3.15), p<0.001), cannabis use (aIRR: 1.87 (1.09±3.20), p = 0.022) and polydrug use (aIRR: 2.34 (1.80±3.04), p<0.001). The presence of alcohol and/or illicit drugs in these patients doubles the risk of trauma recidivism
