ABSTRACT
INTRODUCTION: Burn-injured patients are at particularly high risk of infection; as such one would expect an increased requirement of antibiotics compared to other intensive care patients. There is no data in the literature investigating this hypothesis in Germany. The aim of this study was to determine the antibiotic consumption in severe burn patients and to compare this data with those from surgical intensive care units. PATIENTS AND METHODS: The retrospective study included 136 patients treated in the period from 2013 to 2016 due to a severe burn in the ICU intensive care unit of a regional burn centre. The use of antibiotics was recorded using the electronic medical record. The number of daily doses in Recommended Daily Dose (RDD) and Defined Daily Dose (DDD) based on patient days was calculated. RESULTS: Median [interquartile range] age and total burned surface area were 56.5y [43-75y] and 17 % [8,75; 31] with an ABSI 7 [6; 9]. Antibiotic therapy was given to 82 patients (60.3 %). Antibiotic consumption totaled 77.38 RDD/100 PT or 937.64 DDD/1000 PT. This result was marginally lower than for surgical intensive care units. The most frequently used antibiotics in the burn care setting were fluorquinolones (16.90 RDD/100 PT, 259.91 DDD/1000 PT), followed by carbapenems (12.76 RDD/100 PT, 128.44 DDD/1000 PT) and aminopenicillins/ BLI (11.54 RDD/100 PT, 115.39 DDD/1000 PT). Whilst, the most frequently detected pathogens were Staphylococcus aureus (54.4 %), Enterococcus faecalis (54.4 %), E. coli (37.5 %) and Pseudomonas aeruginosa (36.8 %). CONCLUSION: The total antibiotic consumption in severe burns was not increased compared to other surgical intensive care patients. With regard to individual substance classes, peculiarities can be identified reflecting the particular germ spectrum in this cohort.
