Trial summary

This is an observational study of outcomes of the NHS England-commissioned national respiratory ECMO service, which has been active at six centres since December 2011. The primary outcome of interest is the number of patients who survive to ICU discharge at the ECMO centre. Read more about this study

About this study

This is an observational study of outcomes of the NHS England-commissioned national respiratory ECMO service, which has been active at six centres since December 2011.

The primary outcome of interest is the number of patients who survive to ICU discharge at the ECMO centre. The study also aims to identify factors predictive of outcome.

Read the detailed description

Recent randomised and observational studies suggest there may be a role for extracorporeal membrane oxygenation (ECMO) in patients with severe acute respiratory failure that have not responded to conventional measures.

In 2011, NHS England commissioned a national service to provide ECMO for severe respiratory failure at six centres across the country. Patients with severe respiratory failure are referred to the network if conventional measures are unsuccessful, and if accepted are transferred to an ECMO centre for specialist care. The criteria for admission is at the discretion of clinicians at each centre.

The NHS ECMO registry has been created by cross-referencing data submitted to the Extracorporeal Life Support Organisation (ELSO) in Ann Arbor, Michigan, with a tracker document identifying patients treated within the network. Analysis has been undertaken from December 2018 to March 2019.

What participants receive

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

  • Extracorporeal Membrane OxygenationDevice

    ECMO provides extracorporeal gas exchange through use of a membrane oxygenator. Blood is drained from a central vein and returned after oxygenation into either the venous or arterial circulation dependent on configuration.

What is being measured

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

  1. Survival at ECMO ICU discharge

    The proportion of patients who are alive at discharge from the ICU at the treating ECMO centre.

    Measured: Up to 90 days.

Secondary outcomes (2)
  1. Duration of ECMO treatment.

    The time (hours) where the patient is actively supported by the ECMO circuit.

    Measured: Up to 90 days.

  2. Frequency of Complications

    The proportion of patients experiencing recognised complications of ECMO treatment.

    Measured: Up to 90 days.

Questions about this trial

What is this clinical trial studying?

An observational study of Acute Respiratory Failure, run by University of Cambridge.

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 4 inclusion and 2 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: finished, as of the sponsor's last update on 20 Aug 2019. Status can change between updates, so confirm with the study contact before making plans.

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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Survival at ECMO ICU discharge (time frame: Up to 90 days.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03979222, which also lists 1 linked publication.

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 20 Aug 2019.
