Cocaine use in trauma: the vices-paradox revisited.

BACKGROUND: The "vices-paradox" describes the paradoxical association between illicit substance use and decreased mortality risk in trauma patients. Cocaine's vasoconstrictive effects may decrease hemorrhage but also increase the risk of thromboembolic complications. To clarify the effects of cocaine use on trauma patients, we compared the risk of mortality and thromboembolic complications in patients screening positive for cocaine with those screening negative. METHODS: We searched the Trauma Quality Improvement Program database to identify patients 18 years and over who had presented with a drug and alcohol screen on admission between 2017 and 2019. After excluding all patients who had tested positive for alcohol and substances other than cocaine, we then compared the clinical outcomes of patients who were positive and negative for cocaine use. RESULTS: Of the 312,553 patients identified, 11,942 (3.82%) had tested positive for cocaine. Cocaine users were significantly more likely to present with stab (8.0% vs 3.1%) or gunshot wounds (8.0% vs 3.0%) but had lower rates of mortality (3.6% vs 4.7%), myocardial infarction (0.1% vs 0.2%,) and cerebrovascular accident (0.3% vs 0.4%,). After controlling for covariates, the risk of death, myocardial infarction, and cerebrovascular accident did not significantly differ between cocaine and non-cocaine users. CONCLUSION: Trauma patients positive for cocaine have similar risks of death and thromboembolic complications and so have a similar prognosis to patients negative for all drugs or alcohol, indicating that the "vices-paradox" does not apply to cocaine use. However, these patients more commonly present after penetrating trauma, suggesting cocaine use in hazardous environments.

Emergency medicine (EM) can safely manage geriatric trauma patients sustaining ground level falls: Fostering EM autonomy while safely offloading a busy trauma service.

OBJECTIVE: Limited data exists regarding different specialties care of geriatric (>74 years-old) trauma patients (GTPs). We created a "Tier-III" designation for ground-level fall (GLF) GTPs to be managed by EM, with a trauma consult as needed. MATERIALS AND METHODS: A single-center comparison of PRE (1/1/2013-4/30/2016) versus POST (5/1/2016-11/30/2019) Tier-III GTP GLFs. The primary outcome was mortality. Secondary outcomes included admissions, trauma bay procedures and length of stay (LOS). RESULTS: 1,652 patients (314-PRE vs. 1,338-POST) were included. The admission rate was lower in the POST (56.9% vs. 88.9%, p < 0.001) cohort. There were no differences in LOS or trauma bay procedures between cohorts (p > 0.05). On multivariable analysis there was similar associated risk of mortality between groups (p = 0.68). CONCLUSION: The associated risk of mortality was similar between GLF GTP cohorts managed initially by EM and trauma surgeons, however the admission rate was lower in the POST group suggesting EM management may improve hospital bed utilization.
