Bacteremia of Patient in Pranangklao Hospital

Jariya Phadungpattanodom



Bacteremia is a major cause of death among patients. The incidence and antimicrobial susceptibility data were important tools for patient treatment and infectious control. The objective of this study was to study the rate of infection in blood stream, causative agent and antimicrobial susceptibility pattern of bacteria isolated from blood sample of patients admitted to Phranangklao Hospital. The patient’s data and microbiological test results including blood culture and drug susceptibility were collected between January and December 2016. Among 6,049 patients, bacteremia was found in 523 patients in which 209 patients (40%) were dead. The mean age of patients was 56.5 years (SD = 24.5 years) and the most susceptible group were between 60-79 years of age. Ward unit which found the most bacteremia was Medicine ward. The most underlying disease was renal disease. Length of stay average was 21.8 days (SD = 38). The causative bacteria were found to be gram negative bacilli, gram positive cocci and others for 50.1%, 45.7% and 4.2%, respectively. In this study, ten most common bacteria causing bacteremia were Coagulase Negative Staphylococcus (CoNS), Escherichia coli, Klebsiella pneumoniae, Staphylococcus aureus, Acinetobacter baumannii, Enterococcus faecalis, Pseudomonas aeruginosa, Streptococcus group B, Streptococcus group A and Proteus mirabilis. The drug susceptibility test showed that some were multidrug resistant strains with differences in drug susceptibility pattern. Antimicrobial susceptibility of bacteria isolated from blood should be tested for proper antibiotic drug treatment and effective prevention of antimi- crobial drug resistant in hospital.
