High-Dose Steroids in COVID-19 Related Acute Respiratory Distress Syndrome: A Proposed Protocol

ABSTRACT

Introduction: The introduction of dexamethasone in the treatment of COVID-19 began in late 2020 after evidence emerged demonstrating that treatment with corticosteroids reduced mortality in those infected with severe COVID-19.1 Current guidelines suggest the use of Dexamethasone 6mg OD for 7-10 days for those requiring oxygen. A small proportion of patients in the intensive care unit do not respond to the usual dosing of dexamethasone. A treatment often advocated following discussion with the regional ECMO centre was high-dose steroid therapy.2-3 No guidance existed regarding the use of high-dose steroids in ARDS secondary to COVID-19. We believed there was inconsistency in patient selection, screening, dosing and monitoring. A protocol was needed to simplify this process. Objective(s) To develop a simple protocol for the use of high-dose steroids in COVID-19 related ARDS that provided the user with information on 1. When to consider high-dose steroids 2. The precautions that should be taken to exclude infection prior to commencing high-dose steroids 3. The monitoring required while receiving high-dose steroids 4. A proposed treatment regimen Methodology and Results: A literature review of treatment regimens for high-dose steroids in COVID-19 ARDS was undertaken. We also included trials involving non-COVID-19 ARDS.3-4 A local evidence-based protocol for the use of high-dose steroids in COVID-19 related ARDS was designed. Following peer review by the wider MDT the protocol was first trialled, reviewed, and then adopted. An extended guideline with scientific context together with a quick reference bedside poster were launched. Conclusion(s) The protocol provided a user-friendly summary of the information required to safely use high-dose steroids for the treatment of COVID-19 related ARDS. The algorithm has now been adopted in several units and has been submitted for consideration as a network wide resource. Feedback from users has been positive and we will seek to review and update this guidance as further evidence emerges in this evolving condition.
