Summary
This pragmatic trial of 501 COVID-19 patients with hypoxaemia assessed whether recommendation of awake prone positioning improved clinical outcomes compared with usual care across two US academic medical centres. Patients in the intervention group spent a median of 4.2 hours daily in the prone position versus 0 hours in usual care. The study employed Bayesian proportional odds modelling to evaluate outcomes on a modified WHO severity scale, though specific efficacy results are not disclosed in the abstract provided.
UK applicability
These findings from US hospital settings may have limited direct applicability to UK practice, as clinical protocols, patient populations, and resource availability differ. However, results could inform UK guidance on non-invasive respiratory support strategies for hypoxaemic COVID-19 patients, should the trial demonstrate clinical benefit.
Key measures
Modified WHO ordinal outcome scale (worst hypoxaemia on day 5), progression to mechanical ventilation, hospital mortality, duration of prone positioning per day (median hours)
Outcomes reported
The study measured clinical outcomes using a modified World Health Organization ordinal outcome scale, assessing worst hypoxaemia level on study day 5 and subsequent progression to mechanical ventilation or death. Primary analysis employed Bayesian proportional odds modelling with covariate adjustment for baseline clinical severity.
