Clinical Outcome and Antimicrobial Therapeutic Drug Monitoring for the Treatment of Infections in Acute Burn Patients.

Abstract：

PURPOSE:In critical burn patients, the pharmacokinetic parameters (absorption, distribution, metabolism, and excretion) of many classes of drugs, including antibiotics, are altered. The aim of this study was to compare 2 groups of burn patients undergoing treatment for health care-associated infections with and without therapeutic drug monitoring. METHODS:A retrospective analysis of a clinical intervention (ie, a before/after study) was conducted with patients with health care-associated pneumonia, burn infection, bloodstream infection, and urinary tract infection in the burn intensive care unit of a tertiary care hospital. The patients were divided into 2 groups: (1) those admitted from May 2005 to October 2008 who received conventional antimicrobial dose regimens; and (2) those admitted from November 2008 to June 2011 who received antibiotics (imipenem, meropenem, piperacillin, and vancomycin) with doses adjusted according to plasma monitoring and pharmacokinetic modeling. General characteristics of the groups were analyzed, as were clinical outcomes and 14-day and in-hospital mortality. FINDINGS:Sixty-three patients formed the conventional treatment group, and 77 comprised the monitored treatment group. The groups were homogeneous, median age was 31 years (range: 1-90) and 66% were male. Improvement occurred in 60% of the patients under monitored treatment (vs 52% with conventional treatment); 14-day mortality was 16% vs 14%; and the in-hospital mortality was similar between groups (39% vs 36%). In the final multivariate models, variables significantly associated with in-hospital mortality were total burn surface area ≥30%, older age, and male sex. Treatment group did not affect the prognosis. IMPLICATIONS:Therapeutic drug monitoring of antimicrobial treatment did not alter the prognosis of these burn patients. More trials are needed to support the use of therapeutic drug monitoring to optimize treatment in burn patients.
