COVID-19 Clinical Trial
Official title:
Re-EValuating the Inhibition of Stress Erosions (REVISE) - COVID-19 Cohort Study
Commonly employed medications used in critically ill patients requiring life support include proton pump inhibitors (PPIs). These medications are thought to prevent gastrointestinal (GI) bleeding from stress-induced ulceration. Despite their widespread use, they do hold some risks which include infection in the form of pneumonia and diarrheal illnesses such as Clostridioides difficile infection (C. difficile). Emerging high-quality studies suggest PPI usage does not influence susceptibility to COVID-19 infection, however some studies suggest PPI use leads to poor outcomes in this population, including prolonged time on life-support and death. While we can appreciate the negative effects of PPI may be magnified in the sickest of patients, namely hospitalized patients with COVID-19, the beneficial or potentially harmful role they play in this population remains unclear. We aim to build a clinical profile to further describe critically ill patients with COVID-19 in Ontario using the infrastructure of an ongoing multicenter clinical trial of acid suppression. We will identify characteristics that predict poor outcomes among sick COVID patients, examining the impact of PPIs on this population.
The overall aims are to further characterize the high-risk population of COVID-19 patients nested within the multicenter REVISE trial. Specifically, we plan 1) to explore the impact of PPIs on mechanically ventilated critically ill COVID-19 patients, 2) describe the clinical course for patients with COVID-19 and identify characteristics that predict poor prognosis, and 3) compare outcomes to patients without COVID-19. The overall research questions are as follows: 1. Do critically ill patients projected to receive mechanical ventilation for >48 hours with COVID-19 have different clinical outcomes without PPIs? 2. Are there prognostically relevant demographic, biomarker and clinical data to characterize critically ill patients with COVID-19? 3. Do critically ill patients with COVID-19 have significant higher rates of clinically important GI bleeding, 90-day mortality, and rates of infection when compared to a propensity-matched non-COVID REVISE cohort? To accomplish this, the investigators propose to gather information in patients' medical charts including biomarkers drawn by the ICU team, venous thromboembolism (VTE) and tracheostomy timing, to link with extensive baseline characteristics and outcomes already collected in the REVISE trial (NCT03374800) ;
