About this study

Official title: Awake-Prone Positioning Strategy for Hypoxic Patients With COVID-19: A Pilot Randomized Controlled Trial

This study aims to determine if a strategy of recommending prone (on stomach) positioning of patients positive or suspected positive for coronavirus disease 2019 (COVID-19) requiring supplemental oxygen, but not mechanically ventilated, Is feasible in the inpatient setting. This study will be performed as a pragmatic pilot clinical trial to gain information relevant to the future conduct of a larger trial.

Read the detailed description

Severe acute respiratory syndrome coronavirus-2, SARS-CoV-2, the virus causing coronavirus disease 2019 (COVID-19) pandemic, has rapidly led to significant morbidity and mortality worldwide, primarily through lower respiratory tract involvement progressing from hypoxemia to acute respiratory distress syndrome. Novel approaches to improving oxygenation are urgently needed to limit aerosolization concerns and resource scarcity associated with intubation and, to a lesser extent, other forms of advanced respiratory support.

Prone positioning in mechanically ventilated patients with hypoxemic respiratory failure has been associated with improvement in oxygenation and mortality in patients with acute respiratory distress syndrome (ARDS). The prone position appears to provide more uniform lung perfusion, shifting ventilation to well-perfused lung segments and recruitment of dependent atelectatic regions of lung. Physiological alterations associated with the prone position would foreseeably also apply to spontaneously breathing patients and evidence from small observational studies suggests that prone positioning in non-intubated patients is feasible associated with improvement in oxygenation. However, it remains unknown if a prone ventilation strategy is truly beneficial for non-intubated hypoxic Covid-19 patients, and this question has stimulated interest in the conduct of rigorous randomized controlled trials (RCT).

However, the awake prone strategy is a complex medical intervention with multiple implementation nuances such as adoption, feasibility, and tolerability that may affect successful conduct of a definitive RCT. In order to increase the likelihood of a successful future RCT, the investigators will conduct the APPS pilot study. The overall aim of the APPS pilot trial was to assess feasibility and important contextual factors for a large RCT to compare the clinical effectiveness of an Awake-Prone Positioning Strategy (APPS) for respiratory support versus usual care alone for hypoxic adults with Covid-19.
