Predictive Model for High-Flow Nasal Cannula Failure in COVID-19-related Acute Hypoxemic Respiratory Failure Based on Metabolomics and Clinical Data

Spain111 participantsStarted 2020-03-01

Plain-language summary

The aim of this prospective observational cohort study is to develop a predictive model for high-flow nasal cannula (HFNC) failure in patients with acute hypoxemic respiratory failure (AHRF) caused by SARS-CoV-2. By combining clinical data and metabolomic profiles, the study seeks to answer: \- Can integrating clinical parameters with metabolomic markers enhance the prediction of HFNC failure in AHRF patients? Participants with AHRF due to SARS-CoV-2 receiving HFNC under standard-of-care protocols will be monitored until hospital discharge or death. Blood samples for metabolomic analysis will be collected at inclusion.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * Adult patients (≥18 years old) with acute hypoxemic respiratory failure (AHRF) confirmed as secondary to SARS-CoV-2 infection via PCR testing. * Requirement for high-flow nasal cannula (HFNC) initiated within 48 hours of hospital admission. Exclusion Criteria: * Patients under the age of 18 * Patients with active "do not resuscitate" (DNR) orders at the time of inclusion.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

What they're measuring

Predictive Model Development

Timeframe: From the initiation of HFNC until the need for intubation, hospital discharge, or death, whichever occurs first (up to 28 days). Completed using the Training Cohort (March 2020 to April 2021).
