NCT06035796

Brief Summary

Main purpose: To evaluate the feasibility of tNGS for pathogen detection and drug resistance analysis in VAP patients. Research site and research population: This study is planned to be conducted in hospitals, targeting VAP patients. Perform clinical routine testing and tNGS testing on lower respiratory tract samples (BALF) from VAP patients, and collect patient clinical information. Clinical routine testing includes culture (necessary), microscopy, serology, PCR, etc., and drug sensitivity tests are conducted on positive culture samples as needed. Finally, compare the consistency of tNGS detection results with clinical culture, comprehensive diagnosis, and drug sensitivity results. Further validation was conducted on consistent negative or inconsistent samples through PCR and mNGS.

Outcome Measures

Primary Outcomes (1)

  • tNGS for pathogen detection rate and drug resistance rate in VAP

    Evaluating the feasibility of tNGS for pathogen detection rate and drug resistance rate in VAP patients

    2years

Secondary Outcomes (1)

  • Consistency rate of pathogen detection of tNGS with clinical practice

    2 years

Study Arms (2)

tNGS(targeted second generation sequencing)

tNGS detection of lower respiratory tract samples (BALF) from VAP patients.By means of super-multiple PCR amplification or probe hybridization capture, tNGS can enrich dozens to hundreds of known pathogenic microorganisms and their virulence and drug resistance genes in the samples to be tested, and then conduct high-throughput sequencing.

Device: tNGS

non-tNGS(non-targeted second generation sequencing)

Perform routine clinical testing on lower respiratory tract samples (BALF) from VAP patients and collect patient clinical information. Clinical routine testing includes culture (necessary), microscopy, serology, PCR, etc., and drug sensitivity tests are conducted on positive culture samples as needed.
