Bacteremia situation of Vachiraphuket Hospital, during the years 2013 to 2015

Abstract

            The study of bacteremia and antimicrobial susceptibility pattern in of Vachiraphuket Hospital, during the years 2013 to 2015 in total 8,471 isolates, found Coagulase-negative Staphylococcus
with the highest rate at 24.4% (1,868/8,471 isolates), E.coli 9.6%(731/8,471 isolates), Staphylococcus aureus 8.3% (630/8,471 isolates),K.pneumonia 4.5% (345/8,471 isolates), and A.baumannii 4.4%
(334/8,471 isolates). The results of antimicrobial susceptibility pattern found antimicrobial resistance organisms that are A.baumannii (MDR) at the highest rate 60% (203/334 isolates), K.pneumoniae; ESBL
producing 26.5% (92/345 isolates), E.coli; ESBL producing 24.7%(181/731 isolates), and Staphylococcus aureus; MRSA 17.8% (113/630 isolates) In addition, the study of antimicrobial susceptibility pattern
also found that all of Coagulase-negative Staphylococcus, and Staphylococcus aureus still sensitive to Vancomycin (100%), E.coli and K.pneumoniae still high sensitive to Carbapenems group such as
Ertapenem (100%and 96%), Imipenem (99%and 96%), Meropenem (99% and 95%), Amikacin (98% and 99%), Cepfoperazone/Sulbactam (93%and 84%) and Piperacillin/Tazobactam (94% and 80%) but both
of them had moderate to low level of sensitive to Cephalosporins group.However, A.baumannii still sensitive to Colistin (99%) and Tigecycline (97%) but had low sensitive to other groups of antimicrobial. This study showed that bacteremia was found in medicine ward with the highest rate at 52.44% and the lower rate in newborn baby ward (12.67%), surgical ward (10.48%), ICU medicine ward (10.45%) and pediatric ward (9.47%). In addition, bacteremia was found in male more than female (10.8%) and patients in age 30-55 years were the highest rate at 34.2% and the lower rate at 32.4% were patients in age 55-80 years
