Incidence and mortality of healthcare-associated infections in hospitalized patients with moderate to severe burns.

This study was to examine the incidence of different types, and isolated pathogens, of healthcare-associated infections (HAIs), and also to determine their prognostic factors for mortality.Prospective surveillance was conducted in a medical center from 2005 through to 2016. Multiple logistic regression analysis was performed to assess prognostic factors of mortality.A total of 709 patients with moderate to severe burns were hospitalized. There were 83 patients (11.7%) with HAIs (158 episodes) and 203 isolated pathogens. The most common HAI types were bloodstream infection (BSI) at 39.2% (8.7% of all patients) and central line-associated BSI (mean 4.8 per 1000 central line days). Overall, S. aureus (13.8%) were the most common isolated pathogens, while the most commonly found type of multidrug-resistant pathogen was carbapenems-resistant Enterobacteriaceae (23%). The crude mortality rate was 15.7%, and the independent factors (p < .05) for mortality were BSI (Odds ratio [OR] 2.70), intensive care unit (OR 5.19) and total body surface area with full-thickness injuries ≥50% (OR 5.22).Burn patients with BSI were the most common HAI sites, and this was an independent factor for mortality. Effective integrated care and appropriate infection control can reduce the incidence of infection and death.
