This case series reports that patients with systemic inflammatory disease are at high risk for postoperative complications, type II endoleak, sac expansion, and additional interventions after endovascular aneurysm repair.
To describe the prevalence of preinjury warfarin use in a large national sample of trauma patients and to define the relationship between preinjury warfarin use and mortality.
Retrospective cohort study.
The National Trauma Databank (7.1).
All patients admitted to eligible trauma centers during the study period; 1 230 422 patients (36 270 warfarin users) from 402 centers were eligible for analysis.
Prevalence of warfarin use and all-cause in-hospital mortality. Multivariate logistic regression was used to estimate the odds ratio (OR) for mortality associated with preinjury warfarin use.
Warfarin use increased among all patients from 2.3% in 2002 to 4.0% in 2006 (P < .001), and in patients older than 65 years, use increased from 7.3% in 2002 to 12.8% in 2006 (P < .001). Among all patients, 9.3% of warfarin users died compared with only 4.8% of nonusers (OR, 2.02; 95% confidence interval [CI], 1.95-2.10; P < .001). After adjusting for important covariates, warfarin use was associated with increased mortality among all patients (OR, 1.72; 95% CI, 1.63-1.81; P < .001) and patients 65 years and older (OR, 1.38; 95% CI, 1.30-1.47; P < .001).
Warfarin use is common among injured patients and its prevalence has increased each year since 2002. Its use is a powerful marker of mortality risk, and even after adjusting for confounding comorbidities, it is associated with a significant increase in death.
