Association Between Mucositis Severity and Vancomycin-Resistant Enterococcal Bloodstream Infection in Hospitalized Cancer Patients

Abstract

AbstractObjective:To determine the role of mucositis severity in the development of vancomycin-resistant enterococcal (VRE) bloodstream infection (BSI).Setting:A tertiary-care university medical center.Participants:Hematology-oncology-unit inpatients.Design:Patients with VRE BSI (case-patients) were compared with VRE-colonized (control) patients from September 1994 through August 1997. Oral mucositis severity was recorded on the day of VRE BSI for case-patients and on hospital day 22 (median day of hospitalization of case-patient VRE BSI) for controls. There were 19 case-patients and 31 controls.Results:In univariate analysis, case-patients were significantly more likely than controls to have a higher mucositis severity score, diarrhea, or a higher severity of illness score. In multivariate analysis, only mucositis remained as an independent risk factor, and increasing mucositis score was significantly associated with VRE BSI.Conclusions:Mucositis severity was independently associated with an increasing risk for VRE BSI. Interventions to alter mucositis severity may help to prevent VRE BSI in hospitalized cancer patients.
