Risk factors for multidrug-resistant A. baumannii and P. aeruginosa infection in burn care unit

Infection is a major cause of morbidity and mortality in burns patients. In spite of considerable advances in the treatment of burns, infection continues to pose the greatest danger to burn patients. We aimed to evaluate and present risk factors for multidrug resistant (MDR) Pseudomonas aeruginosa and Acinetobacter baumannii infections which are considered as a challenge to burns.From January 2009 to May 2011, a total of 465 patients hospitalized in Burn Care Unit were retrospectively reviewed including bacteria isolated and antibiotic susceptibility tests.The mean age of patients was 18.6 ±22.0 yr (median=6,1-87 yr). Use of invasive device, lenght of stay in hospital, Intensive care unit lenght of stay and percentage of Total Body Surface Area were statistically significant for MDR A. baumannii and P. aeruginosa. In logistic regression, length of stay and the invasive device usage were found as risk factors for MDR A. baumannii and P. aeruginosa. Strict rules to control infections, lower hospitalization period and reducing the invasive device usage are essential to keep MDR and Nosocomial infections (NIs) rates lowered or at least in a stable phase
