NCT06524765

Brief Summary

In this study, metagenomic sequencing (10G) results of stool samples from health care workers in ICU and non-medical professionals were compared to observe whether there are significant differences in community diversity, structure and function of intestinal microbiota and whether there are drug resistance genes carried by intestinal microbes, so as to determine whether long-term exposure to multi-pathogen environment in ICU has an impact on intestinal microbiota.

Outcome Measures

Primary Outcomes (1)

  • Differences of antibiotic resistance genes-within the gut microbiota

    Metagenomic sequencing (10G) will be performed on three days after inclusion, to compare the differences of antibiotic resistance genes-within the gut microbiota between ICU health care workers and non-medical professionals.

    Within three days after inclusion.

Secondary Outcomes (5)

  • Patient Health Questionnaire (PHQ-9) score.

    Within three days after inclusion.

  • Symptom checklist 90 (SCL-90) score

    Within three days after inclusion.

  • Perceived Stress Scale (PSS) score

    Within three days after inclusion.

  • International Physical Activity Questionnaire (IPAQ) score

    Within three days after inclusion.

  • Pittsburgh sleep quality indexs (PSQI) score

    Within three days after inclusion.

Study Arms (2)

ICU health care workers (exposed group)

The infection rate of multidrug-resistant bacteria in critically ill patients in intensive care unit (ICU) is high, the mortality rate of infected patients is high, which becomes the source of pathogen transmission. The front-line medical staff engaged in ICU are constantly in contact with patients and exposed to the intensive care unit (ICU) environment full of pathogens and even drug-resistant bacteria, and this high-risk contact and exposure makes many pathogenic microorganisms and their drug-resistant genes become part of the intestinal microbiota of ICU medical staff and are carried. Therefore, the exposure factor of the exposure group in this study was ICU environment.

Other: Living conditions

Non-medical professionals (non-exposed group)

This group is a non-exposed group, so the exposed factor is the daily living environment.

Interventions

There are many patients with multi-resistant bacterial infections in intensive care units (ICU), making it possible for a great deal of these pathogens to exist in the ICU environment. The exposure factors in this study were ICU environment or daily living environment.
