Evaluating guideline adherence regarding empirical vancomycin use in patients with neutropenic fever
Abstract
Objective: The purpose of this study was to evaluate the use of empirical vancomycin for patients with neutropenic fever (NF) with regard to adherence to treatment guidelines. Methods: Adult patients with a diagnosis of neutropenia, who met the definition of NF as per treatment guidelines, were identified. Use of vancomycin was evaluated as part of empirical therapy and again after 72 h. Outcomes were assessed using descriptive statistics, the Chi-square or Fisher’s exact test, and univariate exact logistic regression analyses. Results: Sixty-four patients were included. Overall, inappropriate empirical vancomycin use was observed in more than 30% of patients. Of 35 patients with indications for empirical vancomycin, only 68% received it. At 72 h, appropriate vancomycin continuation, de-escalation, or discontinuation occurred in 21 of 33 patients. On univariate regression, hematological malignancy was associated with appropriate empirical vancomycin prescribing, whether initiating or withholding (odds ratio 4.0, 95% confidence interval 1.31–12.1). No variable was independently associated with inappropriate continuation at 72 h. Conclusions: There is poor guideline adherence to vancomycin prescribing as empirical therapy and at 72-h reassessment in patients with NF. Further efforts are needed to foster a more rational use of vancomycin in patients with NF. Keywords: Antibiotics, Neutropenia, Neutropenic fever, Vancomycin
