研究概览
简要总结
This is an experimental study of participants who had positive blood culture to compare time to appropriate antibiotic between using Microarray Assay and Mass Spectrometry to bacterial Identification.
详细描述
Between June to Dec 2018, 200 participants those met the eligibility criteria were enrolled in this study that is a quasi experimental study. All participants were empirical antibiotic therapy by infectious physician. 100 patients in Pre-intervention group had bacterial identification by Mass spectrometry technique from bacterial colony and 100 patients in Post-intervention group had bacterial identification by Microarray assay from blood culture. Antibiotic adjustment were considered after bacterial identification and result of antibiotic susceptibility testing. Then all participants were re-evaluated outcome after treatment. Finally, the results were ready to analysis in January 2019.

研究组 & 干预措施
Pre-intervention group
100 participants received empiric antibiotic by ID physician, bacterial identification by Mass spectrometry technique
干预措施: Mass spectrometry (Diagnostic Test)
Post-intervention group
100 participants received empiric antibiotic therapy by ID physician, bacterial identification by Microarray assay from blood culture and confirm with Mass spectrometry technique
干预措施: Microarray assay (Diagnostic Test)
