Antibiotic Resistance and Mortality in Children with Nosocomial Bloodstream Infection in a Teaching Hospital in Indonesia.

Nosocomial infection is a major problem in hospitals worldwide. Understanding patterns of bacterial etiology and antibiotic susceptibility are important factors to combating nosocomial infection. Among children with nosocomial bloodstream infection (BSI), we identified pathogens and determined antibiotics resistance patterns and mortality rates for antibiotic-susceptible and multidrugresistant (MDR) infection in patients with nosocomial BSI in pediatric wards and PICU at Dr Sardjito Hospital, Indonesia during December 2010 to February 2013. Of 174 isolates from 170 patients, 168 pathogens were bacteria, of which 148 were gram-negative. Pseudomonas aeruginosa, Klebsiella spp, Enterobacteriaceae, Acinetobacter baumanii, and Escherichia coli was found in 55%, 6%, 4%, 1%, and <1%, respectively of the isolates. Imipenem, amikacin, ciprofloxacin, and ceftazadime had the highest sensitivity to nosocomial pathogens at 86%, 84%, 84%, and 75%, respectively. Eleven patients had MDR-infections, 7 of whom died. Among 153 patients infected with bacteria resistant to <3 classes of antibiotics (non-MDR), mortality was 40%, and among 4 patients with fully drug-susceptible sepsis only one died. Thus, substantial mortality was observed in children with nosocomial-BSI, particularly with MDR pathogens. Given the further high risk of resistance with wider use of carbapenems, third generation cephalosporins and flouroquinolones, prevention should be given highest priority in combating hospital-acquired infection.
