Prospective analysis of nosocomial infections in a burn care unit, Turkey.

BACKGROUND &
OBJECTIVE: Prevention of infection in burned patients poses a great challenge as infection is the most common cause of mortality after burn injury. An analysis of burned patients, admitted and treated between January 2004 and December 2005 in a nine-bed burn unit in Turkey, was performed prospectively to identify the common pathogens and incidence of nosocomial infection in these patients.
METHODS: Of the 182 burn cases admitted to Burn Care Unit during the study period, 169 met the inclusion criteria. Information related to nosocomial infection (NI) was collected. Samples were collected for culture and microorganisms isolated were tested for antimicrobial sensitivity.
RESULTS: Of the 169 burn patients, 127 acquired 166 nosocomial infection (NI) (15.7% pneumonia, 56.0% burn wound infection, 8.4% urinary tract infection and 19.9% blood stream infection) with an overall NI rate of 18.2 per 1000 patient-days. The mean age (38 +/- 21 yr), the mean length of hospitalization (45.06 +/- 11.67 days) and the total burned surface area (TBSA) (34.58 +/- 18.46%) of the patients with NI were higher than those of the patients with non NI (23 +/- 17 yr), (16.38 +/- 11.14 days) and (12.44 +/- 8.69%) (P=0.03, P=0.001, P=0.01) respectively. By multiple logistic regression analysis, TBSA co-morbidities, broad spectrum antibiotic usage and invasive devices usage were significantly related to acquisition of NI. Pseudomonas aeruginosa (57%), Acinetobacter baumannii (21%) and Staphylococcus aureus (14%) were the most common resistant organisms isolated. INTERPRETATION &
CONCLUSION: Our findings emphasize the need for careful disinfection and more strict infection control procedures in areas that serve immunosupressed individuals, such as burn patients.
