About this study

Official title: Multidimensional Digital Phenotyping of High-Risk Chronic Disease Patients With Ventilator Dependence

This project plans to employ a multi-center retrospective and prospective cohort study design. It aims to collect data on ventilator support strategies, duration of invasive mechanical ventilation, incidence of ventilator dependence, high-risk factors for ventilator dependence, and in-hospital mortality rates among different chronic disease populations in the ICU. This will involve combining unstructured data with real-time bedside multi-dimensional high-frequency data (including dynamic changes in data volume, respiratory mechanics, diaphragm ultrasound, EIT, diaphragm electrical activity, and other monitoring parameters) to construct digital phenotypes for chronic disease patients with ventilator dependence and identify high-risk factors for ventilator dependence in this population.

Specifically, the research will:

Utilize an integrated modular intelligent respiratory monitoring system, previously developed by the project team, to achieve dynamic monitoring of multi-dimensional indicators.

Systematically collect dynamic clinical characteristics of mechanical ventilation dependence in chronic disease populations through retrospective and prospective cohort studies, and employ multivariate statistical analysis, machine learning, and other techniques to identify no fewer than 5-6 high-risk factors for ventilator dependence in chronic disease patients.

Establish a data ecosystem suitable for chronic disease patients undergoing mechanical ventilation, build a multi-dimensional high-frequency data platform for chronic ventilator-dependent populations, map the full cycle from intubation to mechanical ventilation support, weaning, and extubation, and construct multidimensional digital phenotypes for high-risk chronic disease patients with ventilator dependence.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Proportion of ventilator dependence(mechanical ventilation time≥7 days) in chronic disease patients receiving invasive mechanical ventilation

    the proportion of patients who achieve sustained liberation from invasive mechanical ventilation within 7 days of the initial intubation.

    Measured: From enrollment to 7 days

Secondary outcomes (14)
  1. Proportion of chronic disease patients still receiving IPPV at 14/21 days after mechanical ventilation

    the proportion of patients who achieve sustained liberation from invasive mechanical ventilation within 14 and 21 days of the initial intubation.

    Measured: 21 days

  2. Success rate of the first Spontaneous Breathing Trial (SBT) in chronic disease patients

    Measured: during hospitalization,assessed up to 28 days

  3. Time to first extubation in chronic disease patients

    Measured: during hospitalization,assessed up to 28 days

  4. Proportion of first extubation failure in chronic disease patients

    Measured: during hospitalization,assessed up to 28 days

  5. High-risk factors for first extubation failure in chronic disease patients

    Measured: during hospitalization,assessed up to 28 days

  6. ICU mortality rate

    Measured: during hospitalization,assessed up to 28 days

  7. In-hospital mortality rate

    Measured: during hospitalization,assessed up to 28 days

  8. ICU length of stay

    Measured: during hospitalization,assessed up to 28 days

  9. Total hospital length of stay

    Measured: during hospitalization,assessed up to 28 days

  10. Duration of invasive mechanical ventilation

    Measured: during hospitalization,assessed up to 28 days

  11. Incidence of Ventilator-Associated Pneumonia (VAP)

    Measured: during hospitalization,assessed up to 28 days

  12. Proportion of patients undergoing tracheostomy

    Measured: during hospitalization,assessed up to 28 days

  13. Time of tracheostomy

    among those who receive tracheostomy

    Measured: during hospitalization,assessed up to 28 days

  14. High-risk factors for ventilator dependence in chronic disease patients

    Measured: during hospitalization,assessed up to 28 days

Questions about this trial

What is this clinical trial studying?

An observational study of Ventilator Dependency, run by China-Japan Friendship Hospital at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: enrolling by invitation, as of the sponsor's last update on 18 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Proportion of ventilator dependence(mechanical ventilation time≥7 days) in chronic disease patients receiving invasive mechanical ventilation (time frame: From enrollment to 7 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Jun 2026; AzTrials last refreshed its copy on 6 Nov 2026.
