Abstract
The objective of this study is to review the literature on multidrug-resistant bacteria (MDRB) outbreaks in burn units according to the outbreak reports and intervention studies of nosocomial infection statement. A PubMed search engine was enlisted to identify reports, in English and French, on MDRB outbreaks in burn units, with no date restrictions, using the following key words: ("burn" OR "burns" OR "severe burn") AND ("unit" OR "critical care" OR "acute care" OR "intensive care" OR "center" OR "centre" OR "department") AND ("outbreak" OR "epidemic") AND ("resistant" OR "multidrug-resistant" OR "resistance" OR "MDR" OR "MDRO"). Twenty-nine articles on such outbreaks in burn units were analyzed. A wide variety of these outbreaks were studied in terms of the microbial agents involved, length of outbreak, and attack rate (1.9-66.7%). The most frequent bacteria were methicillin-resistant Staphylococcus aureus and Acinetobacter baumannii. Screening of staff revealed carrier rates of 0 to 20% in 16 studies. Environmental samples were taken in 21 studies and were positive in 14 of them. The mortality rate among infected patients varied from 0 to 33%. Implementation of isolation precautions did not always suffice, with unit closure being necessary in five outbreaks. The lack of consensus on how to manage such outbreak was highlighted. MDRB infections or colonizations are responsible for increased morbidity and mortality in vulnerable burn patients. Their management is problematic because of multifactorial transmission and limited therapeutic possibilities.
