About this study
Official title: h Can Provide the Detection Results of Pathogen Type and Resistant Gene. This Study is a Prospective Multi Centers Study to Explore Using the New Diagnostic Tool of " RPIP " and the Different Detection Methods of Next Generation Sequencing and Multiplex PC R in Patients With Pneumonia in ICU. Further Compare the Difference of Pathogen Identification and Clinical Impact by Different Diagnostic Methods.
Pneumonia, pathogen involved to lower respiratory tract and leading lung parenchyma infection, is one of the three most common infectious diseases in the world. Rapidly and correctly diagnosis and prescription could reduce the complication, length of hospitalization and mortality rate, especially for the critically patients in intensive care unit. Among the current microbiological diagnostic methods, the current traditional culture combined with biochemical identification method is easily affected by the drug using and different species, and time consuming. Although other diagnostic methods like MALDI-TOF MS、multiplex PCR also common and available in clinically, but owing some limitations like lower resolution, inability to afford the drug sensitivity of pathogen. Whole genome sequencing is one of the potential developing tools in pathogen identification, especially the next-general sequencing. The advantage of Metagenomic NGS (mNGS) in the application of clinical microbial detection is that it can identify various species and provide drug resistance gene information at the same time. However, background DNA from non-pathogens can highly affect the sensitivity of next-generation sequencing (untargeted mNGS). The Respiratory Pathogen ID/AMR Panel (RPIP) is a targeted mNGS developed by Illumina, which can provide the detection results of pathogen type and resistant gene. This study is a prospective multi-centers study to explore using the new diagnostic tool of " RPIP " and the different detection methods of next-generation sequencing and multiplex PCR in patients with pneumonia in ICU. Further compare the difference of pathogen identification and clinical impact by different diagnostic methods.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| ICU pneumonia patient | Standard-of-care test: Bacterial and fungal testing: BAL and ETA or sputum specimens are subjected to Gram staining, and aerobic, anaerobic, and fungal cultures are performed. Mycobacterium culture is performed, and PCR is used to detect mycobacterial DNA. Other tests included atypical pathogen, aspergillus and virus survey. FilmArray PP can detect 15 bacterial species, 3 atypical bacteria, 8 viruses, and detect 7 antimicrobial resistance genes. Respiratory Pathogen ID/AMR enrichment (RPIP): According to the manufacturer's instructions, the workflow includes nucleic acid extraction, cDNA synthesis, sequencing library construction, target amplification, library quality testing, sequencing, and analysis. Untargeted mNGS: The sample is outsourced to a biotechnology company for mNGS analysis. |
What is being measured
The primary outcome is the main question the study is designed to answer.
The expected outcomes to validate the effectiveness of RPIP application in the treatment of pneumonia patients in intensive care units, and to evaluate the value of this method in pathogen identification and clinical treatment decision-making.
The turnaround time between RPIP results and the final report of the standard test is compared to evaluate the time saved by using RPIP. The proportion of clinical treatment strategy adjustments prompted by RPIP results is analyzed, as well as the proportion of inappropriate empirical treatments. It also analyzes whether adjustments in treatment strategies have an impact on mortality.
Measured: After obtaining informed consent, samples will be collected from ICU patients with severe pneumonia at that hospitalization.
Secondary outcomes (1)

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Pneumonia, pathogen involved to lower respiratory tract and leading lung parenchyma infection, is one of the three most common infectious diseases in the world. Rapidly and correctly diagnosis and prescription could reduce the complication, length of hospitalization and mortality rate, especially for the critically patients in intensive care unit. Among the current microbiological diagnostic methods, the current traditional culture combined with biochemical identification method is easily affected by the drug using and different species, and time consuming. Although other diagnostic methods like MALDI-TOF MS、multiplex PCR also common and available in clinically, but owing some limitations like lower resolution, inability to afford the drug sensitivity of pathogen. Whole genome sequencing is one of the potential developing tools in pathogen identification, especially the next-general sequencing. The advantage of Metagenomic NGS (mNGS) in the application of clinical microbial detection is that it can identify various species and provide drug resistance gene information at the same time. However, background DNA from non-pathogens can highly affect the sensitivity of next-generation sequencing (untargeted mNGS).
