|Hypoxemic Respiratory Failure Oxygen Toxicity||Drug: Oxygen||Phase 4|
Acutely ill adult COVID-19 patients with hypoxaemic respiratory failure admitted to the intensive care unit (ICU) are at risk of life-threatening hypoxia, and are provided supplementary oxygen. Liberal use of supplementary oxygen may increase the number of serious adverse events including death. However, the use of supplementary oxygen therapy, and the optimal oxygenation target in COVID-19 patients have not yet been studied.
The World Health Organisation (WHO) recommends an oxygen therapy during resuscitation of COVID-19 patients to achieve an SpO2 of 94% or more, and 90% or more when stable (non-pregnant patients). The Surviving Sepsis Campaing (SSC) recommends a conservative oxygenation strategy for COVID-19 patients targeting an SpO2 no higher than 96%. Both are based on a systematic review and metanalysis from 2018, investigating the association with mortality and higher versus lower oxygenation strategies in critically ill patients in general.
COVID-19 patients admitted to the ICU and treated with positive pressure ventilation fulfil the 2012 Berlin criteria for acute respiratory distress syndrome (ARDS). Current practice regarding supplementary oxygen therapy in patients with ARDS follows the regimen used in an randomised clinical trial (RCT) from 2000 comparing lower versus higher tidal volumes; i.e. a partial pressure of arterial oxygen (PaO2) of 55-80 mmHg (7.3-10.7 kPa) or a peripheral oxygen saturation (SpO2) of 88-95%.
Of note, a recent published RCT demonstrated a lowered all-cause mortality when targeting a higher oxygenation target (PaO2: 12-14 kPa [90-105 mmHg]) compared to a lower oxygenation target (PaO2: 7.3-9.3 [55-70 mmHg]) in ARDS patients.
The quality and quantity of the current body of evidence regarding oxygenation targets in ARDS is still low.
The aim of the HOT-COVID trial is to evaluate the benefits and harms of two targets of partial pressure of oxygen in arterial blood (PaO2) in guiding the oxygen therapy in acutely ill adults COVID-19 patients with hypoxaemic respiratory failure at ICU admission.
The HOT-COVID trial is an amendment to the HOT-ICU trial (NCT03174002)

Oxygen administration to achieve a PaO2 of 8 kPa (60 mmHg) from ICU admission to ICU discharge
Other Name: Inspired oxygen

Other Name: Inspired oxygen
- Days alive without organ support [ Time Frame: Within 90 days ]Percentage of days alive and free from mechanical ventilation, circulatory support and renal replacement therapy
- 90-days mortality [ Time Frame: 90 days ]All-cause mortality 90 days after randomisation
- Days alive out of the hospital [ Time Frame: Within 90 days ]Percentage of days alive out of the hospital
- Number of patients with one or more serious adverse events [ Time Frame: Until ICU discharge, maximum 90 days ]Serious adverse events are defined as new episode of shock and new episodes of ischaemic events including myocardial or intestinal ischaemia or ischaemic stroke
- 1-year mortality [ Time Frame: 1 year ]All-cause mortality 1 year after randomisation
- Quality of life assessement using the EuroQoL EQ-5D-5L telephone interview [ Time Frame: 1 year ]EQ-5D-5L 1-year after randomisation
- Cognitive function 1-year after randomisation as assessed using the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) score in selected sites [ Time Frame: 1 year ]RBANS score 1 year after randomisation at selected sites. The overall RBANS global cognition score, as well as each cognitive domain score, range from 40 to 160 with 100 ± 15 being the age-adjusted mean ± standard deviation. Higher scores indicate better performance.
- Carbon monoxide diffusion capacity [ Time Frame: 1 year ]Carbon monoxide diffusion capacity (DLCO) 1 year after randomisation at selected sites.
- A health economic analysis [ Time Frame: 90 days ]Cost-effectiveness versus cost-minimisation analyses after completion of the trial, based on the primary outcome.
