Trial summary

The main objective of the study is to assess the "FreeDom" innovative strategy (FreeO2 at Domicile) to reduce hospitalization duration in patients with COPD exacerbation. This strategy associates early hospital discharge, automated O2 flow weaning with FreeO2 system, telemedicine and tele-rehabilitation. Read more about this study

About this study

Official title: FreeDom : Innovative Strategy for the Management of COPD Exacerbations Combining Early Hospitalisation Discharge, Automated Oxygen Weaning at Home, Telemedicine and Tele-rehabilitation

The main objective of the study is to assess the "FreeDom" innovative strategy (FreeO2 at Domicile) to reduce hospitalization duration in patients with COPD exacerbation. This strategy associates early hospital discharge, automated O2 flow weaning with FreeO2 system, telemedicine and tele-rehabilitation.

The main hypothesis of this study is that the FreeDom strategy will reduce the number of hospitalization day by 50 percent at day 30.

Read the detailed description

The main objective of the study is to assess the "FreeDom" innovative strategy (FreeO2 at Domicile) to reduce hospitalization duration in patients with COPD exacerbation. This strategy will enable an early return home, patients using an innovative device that automatically adjusts and wean the oxygen flow (FreeO2 system) coupled to telemedicine and tele-rehabilitation.

The main hypothesis of this study is that a strategy for an early return home with a home hospitalization managed by telemedicine will reduce the length of hospitalization by 50 percent from 30 days.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • ControlOther

    Also called Usual oxygen administration and usual hospitalization

    The hospitalization will take place in the usual setting and the hospital discharge will be decided by pulmonologists according to the usual criteria

  • FreeDomDevice

    Also called Early Hospital discharge with home hospitalisation

    Early return home, patients using an innovative device that automatically adjusts and wean the oxygen flow (FreeO2 system) coupled to telemedicine and tele-rehabilitation

Receives: Other: Control
FreeDomActive comparatorFreeDom strategy (early discharge, automated weaning at home, telemedicine, telereadaptation): -initial conventional hospitalization before discharge home, O2 flow rate automatically titrated by FreeO2 (based on a SpO2 target). The hospital discharge will be possible if the definite criteria are met. After hospital discharge, patient will have home hospitalisation. Automated oxygen flow titration, patient education will be conducted for using the telemedicine system, for questionnaires and for the tele-rehabilitation program will be initiated for home hospitalization,

What is being measured

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

  1. The number of hospital days during COPD exacerbation at day 30.

    The objective of the study is to reduced the hospitalisation days by 50 % at day 30 during COPD exacerbation

    Measured: 30 days

Secondary outcomes (5)
  1. Rate of Emergency consultation and hospital readmission

    Rate of Emergency consultation and hospital readmission

    Measured: 1 and 3 months

  2. Health Related Quality of Life

    Survey of health related quality of life

    Measured: 1 and 3 months

  3. Cost of care at 3 months

    Economic evaluation about these 2 different strategy of COPD exacerbation management using micro-costing approach and including the cost of the FreeO2 technology

    Measured: 3 months

  4. Oxygenation data (% of time in the SpO2 target, % of time with hypoxemia, % of time with hyperoxia)

    The continuous measurement of SpO2 and O2 flow rate with the FreeO2 device (only in the FreeDom strategy) will allow the calculation of the % of time within the SpO2 target (recorded in the FreeO2) ± 2%, with hypoxemia (% of time with SpO2 < 85%) and with hyperoxia (% of time above SpO2 target +5%)

    Measured: From inclusion to hospital discharge and from hospital discharge to the end of oxygen therapy (around one week after discharge)

  5. Number of consultations

    Number of consultation : phone call, video consultation, rehabilitation, home visit

    Measured: 3 months

Questions about this trial

What is this clinical trial studying?

A study testing FreeDom in people with Oxygen Deficiency and COPD Exacerbation, run by Laval University at 1 site in Canada.

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 6 inclusion and 9 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: under way, not looking for participants, as of the sponsor's last update on 4 Nov 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 Canada. 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?

The number of hospital days during COPD exacerbation at day 30. (time frame: 30 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 4 Nov 2026.
