Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

1. Baseline period: 1) Collect and record demographic information: date of birth, initials, gender and age; 2) Collect and record medical history and physical examination information: vital signs, height, weight, physical examination of various systems of the whole body, past and present medical history, smoking history, drinking history and infected site; 3) Collect and record the disease severity and organ dysfunction scores: gastrointestinal dysfunction score (GIDs score), acute physiological and chronic health status score (APACHE II) and SOFA score; 4) Collect and record clinical treatment information: antibiotic treatment scheme, sedative and analgesic drug scheme, vasoactive drug scheme and vasoactive drug dependence index; 5) Collect and record the laboratory examination results in the normal diagnosis and treatment process: pathogenic examination sampling method, pathogenic examination results, blood gas analysis, shock index, Pro-BNP, infection indicators (white blood cell count, neutrophil count, lymphocyte count, monocyte count, C-reactive protein, procalcitonin, cytokine monitoring (IL-2, IL-4, IL-4, IL-6, IL-6, IL-6, IL-6, IL-6, IL-6, 6, 6) Collect and record the results of gastrointestinal ultrasound examination: gastric antrum area, left descending colon diameter and right ascending colon diameter. 7) Collect and record the inspection results of intra-abdominal pressure. 8) Collect blood samples left over from routine diagnosis and treatment: evaluate and record the composition of blood flora of patients through NGS. 9) Collect waste stool samples from routine diagnosis and treatment: evaluate and record the composition of intestinal flora of patients through NGS. 10) Collect the remaining discarded bronchoalveolar lavage fluid from routine diagnosis and treatment, and evaluate and record the composition of pulmonary flora of patients through NGS. 11) Collect the bacteria in the ICU ward environment and evaluate and record the composition of the bacteria in the ICU ward environment through NGS: After cleaning the ICU ward for 7 hours, conduct two consecutive sampling activities on the ICU ward of each enrolled patient, specifically rubbing the hard surface of the ICU ward (including the floor and the footboard of the hospital bed) with a sterile artificial swab on an area of 10 × 10cm. The swab was pre-wetted in sterile trypsin solution (TSB) or normal saline, then refrigerated in 5 mL TSB or 0.4 mL normal saline and transported to the laboratory. The composition of environmental flora in ICU ward of patients was analyzed and recorded by NGS within 24 hours. 2, routine diagnosis and treatment period: 1) Collect and record the GIDs scores of patients every day within 2 weeks after admission; 2) Collect and record the following indicators on the 1st, 3rd, 7th and 14th day after admission and when the GIDs score changes: A) Medical history and physical examination information: vital signs, infection site; B) Disease severity and organ dysfunction score: gastrointestinal dysfunction score (GIDs score), acute physiological and chronic health status score (APACHE II) and SOFA score; C) Clinical treatment information: antibiotic treatment scheme, sedative and analgesic drug scheme, vasoactive drug scheme and vasoactive drug dependence index; D) Laboratory examination results in the normal diagnosis and treatment process, such as: pathogen detection, blood gas analysis, shock index, Pro-BNP, infection indicators (white blood cell count, neutrophil count, lymphocyte count, monocyte count, C-reactive protein, procalcitonin, cytokine monitoring (IL-2, IL-4, IL-6, IL-6). E) Gastrointestinal ultrasound examination results: including antrum area, left descending colon diameter and right ascending colon diameter. F) Examination results of intra-abdominal pressure. G) Collect the blood samples left over from routine diagnosis and treatment: evaluate and record the composition of blood flora of patients through NGS. H) Collecting the waste stool samples from routine diagnosis and treatment: evaluating and recording the composition of intestinal flora of patients through NGS. I) Collect the remaining discarded bronchoalveolar lavage fluid from routine diagnosis and treatment, and evaluate and record the composition of pulmonary flora of patients through NGS. J) Collect the bacteria in the ICU ward environment and evaluate and record the composition of the bacteria in the ICU ward environment through NGS: After cleaning the ICU ward for 7 hours, conduct two consecutive sampling activities on the ICU ward of each enrolled patient, specifically rubbing the hard surface of the ICU ward (including the floor and the footboard of the hospital bed) with a sterile artificial swab on an area of 10 × 10cm. The swab was pre-wetted in sterile trypsin solution (TSB) or normal saline, then refrigerated in 5 mL TSB or 0.4 mL normal saline and transported to the laboratory. The composition of environmental flora in ICU ward of patients was evaluated and recorded through NGS within 24 hours. 3. Follow-up period: 1) When the patient leaves the hospital, the total length of stay in ICU and the mortality rate during stay in ICU are collected by consulting the medical record system. 2) Follow-up by telephone and collect the mortality within 60 days.
