Summary: | Blood culture is a crucial investigation with major implication in the management of severe infection especially
on the best-appropriate selection of anti-microbial therapy. Blood culture contamination can lead to adverse
consequences such as inappropriate use of antibiotics, increased antibiotic resistance and prolonged hospital
stay. The present study aimed to determine the prevalence of blood culture contamination and to investigate the
factors associated with blood culture contamination such as patients, healthcare providers and environmental at
Emergency Department, Hospital Universiti Sains Malaysia. A prospective cross-sectional study was conducted
on sepsis, severe sepsis and septic shock patients from 1st September 2012 to 31st August 2013. One hundred
and thirty six (136) consented patients who fulfilled criteria according to International Sepsis Guidelines and
required intravenous antibiotics were enrolled into the study. Blood culture was processed according to the
recommendations of the Clinical and Laboratory Standard Institute.Positive blood cultures were 44 (32.4%)
with 27 of them were contaminated. The prevalence of blood culture contamination in the study population was
19.9%. Night shift work (OR, 4.73; CI, 1.35-16.57; p=0.015), semi-critical zone in triage (OR, 3.78; CI, 1.47-
9.73; p=0.006) and patients who have stroke (OR, 5.49; CI, 1.36-22.19; p=0.017) were found to be significantly
associated with the risk for blood culture contamination. Cultures taken during night shift work, semi critical
zone in triage and patients who have stroke are associated with the risk for blood culture contamination. These
findings should be regarded as a time for change and provide an impetus towards improving patient care. |
