Background: COVID-19 has become the commonest cause of ARDS world-wide. Features of the pathophysiology and clinical presentation partially distinguish it from “classical” ARDS. A RAND analysis gauged the opinion of an expert panel about the management of ARDS with and without COVID-19 as the precipitating cause, using recent UK guidelines as a template. Methods: An 11-person panel comprising intensive care practitioners rated the appropriateness of ARDS management options at different times during hospital admission, in the presence or absence of, or varying severity of SARS-CoV-2 infection on a scale of 1-9 (where, 1-3 is inappropriate, 4-6 is uncertain and 7-9 is appropriate). A summary of the anonymised results was discussed at an online meeting moderated by an expert in RAND methodology. The modified online survey comprising 76 questions, subdivided into: investigations 16, non-invasive respiratory support 18, basic ICU management of ARDS 20, management of refractory hypoxaemia 8, pharmacotherapy 7, and anticoagulation 7, was completed again. Results: Disagreement between experts was significant only when addressing the appropriateness of diagnostic bronchoscopy in patients with confirmed or suspected COVID-19. Adherence to existing published guidelines for the management of ARDS for relevant evidence-based interventions was recommended. Responses of the experts to the final survey suggested that the supportive management of ARDS should be the same, regardless of a COVID-19 diagnosis. For ARDS patients with COVID-19, the panel recommended routine treatment with corticosteroids and a lower threshold for full anticoagulation based on a high index of suspicion for venous-thrombo-embolic disease. Conclusion: The expert panel found no reason to deviate from the evidence based supportive strategies for managing ARDS outlined in recent guidelines.
