Effect of a Contamination Prevention Activity Against Contamination of Blood Culture
Background
Blood culture is important in the diagnosis of blood infections and the identification of treatment strategies. Increased contamination in blood culture is a reduction in quality of care. This retrospective observational study, set in an emergency department in Japan, aims to elucidate the contamination rate before and after the introduction of contamination prevention activities.
Methods
We compared the contamination rates before and one year after contamination prevention activities. Specifically, these activities included a novel and specific use of a blood culture cart and adherence to a checklist. The checklist included noting the actual site of collection, the method of disinfection, and whether gloves were worn.
Results
There were 1184 and 1129 blood culture samples before and after the preventive activities, respectively. The rates of contamination were 2.03% (95% Cl = 1.30% to 3.00%) and 1.24% (95% Cl = 0.68% to 2.07%), respectively.
Conclusion
Prevention activities including specific use of a blood culture cart and careful adherence to a checklist were not associated with a significant decrease in contamination rate in our hospital. Further studies based in hospitals with greater rates of contamination may see higher rates of reduction.
期刊介绍：
The Journal of Evaluation in Clinical Practice aims to promote the evaluation and development of clinical practice across medicine, nursing and the allied health professions. All aspects of health services research and public health policy analysis and debate are of interest to the Journal whether studied from a population-based or individual patient-centred perspective. Of particular interest to the Journal are submissions on all aspects of clinical effectiveness and efficiency including evidence-based medicine, clinical practice guidelines, clinical decision making, clinical services organisation, implementation and delivery, health economic evaluation, health process and outcome measurement and new or improved methods (conceptual and statistical) for systematic inquiry into clinical practice. Papers may take a classical quantitative or qualitative approach to investigation (or may utilise both techniques) or may take the form of learned essays, structured/systematic reviews and critiques.
