INTRODUCTION: We describe incidence and patient factors associated with augmented renal clearance (ARC) in adult intensive care unit (ICU) patients. MATERIALS AND METHODS: A prospective observational study in a mixed cohort of surgical and medical ICU patients receiving antimicrobial therapy at the Ghent University Hospital, Belgium. Kidney function was assessed by the 24-hour creatinine clearance (Ccr); ARC defined as at least one Ccr of >130 mL/min per 1.73 m2. Multivariate logistic regression analysis: to assess variables associated with ARC occurrence. Therapeutic failure (TF): an impaired clinical response and need for alternate antimicrobial therapy. RESULTS: Of the 128 patients and 599 studied treatment days, ARC was present in 51.6% of the patients. Twelve percent permanently expressed ARC. ARC patients had a median Ccr of 144 mL/min per 1.73 m2 (IQR 98-196). Median serum creatinine concentration on the first day of ARC was 0.54 mg/dL (IQR 0.48-0.69). Patients with ARC were significantly younger (P<.001). Age and male gender were independently associated with ARC whereas the APACHE II score was not. ARC patients had more TF (18 (27.3%) vs. 8 (12.9%); P=.04). CONCLUSION: ARC was documented in approximately 52% of a mixed ICU patient population receiving antibiotic treatment with worse clinical outcome. Young age and male gender were independently associated with ARC presence.
