LAKE BUENA VISTA, FLA. – Trauma patients on contact isolation were nearly six times more likely to develop venous thromboembolism (VTE) as those who were not isolated, based on an analysis of 4,317 patients.
VTE occurred in 17.5% (44/251) of patients on contact isolation and 3.5% (141/4,066) of patients who were not isolated (P < .0001). Injury Severity Score (ISS), age, male gender, and obesity also were significantly associated with the risk of VTE.
The relationship between VTE risk and contact isolation remained significant after adjusting for gender, age, ISS, and comorbidities (odds ratio, 3.28; P < .0001), Dr. Robert Ferguson reported at the annual scientific assembly of the Eastern Association for the Surgery of Trauma.
Odds ratios also were significantly elevated for obesity (OR, 2.35; P < .006), male gender (OR, 2.1; P < .0001), ISS (OR, 1.08; P < .0001), and age (OR, 1.02; P < .0001). The presence of diabetes, dementia/Alzheimer’s, history of cerebrovascular accident, psychiatric disease, cirrhosis, cancer, or alcohol abuse was not statistically significant.
The increased risk for VTE in trauma patients on contact isolation “is likely multifactorial in nature and is related but not limited to decreased ambulation, noncompliance with prophylaxis, and restricted access by staff,” said Dr. Ferguson, a third-year resident at the Virginia Tech, Roanoke.
The risk:benefit ratio of contact isolation in the trauma population needs to be reevaluated, the researchers concluded. “We encourage hospital committees to alter protocols and supplement strategies such as staff education, dedicated ambulation areas and/or isolation wards, and eliminate contact isolation following routine methicillin-resistant Staphylococcus aureus surveillance screening.”
Dr. Ferguson and his coauthors reported having no financial disclosures.
