Awake Proning for Nonintubated Adult Hypoxic Patients with COVID-19: A Systematic Review of the Published Evidence.

Awake proning is an intervention that is being advocated for COVID-19 patients and has been suggested to improve the oxygenation, thereby decreasing oxygen requirements. We performed this systematic review with the aim of appraising the latest published evidence on the clinical effectiveness of awake proning in COVID-19 patients. PubMed, EMBASE, The Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science, Google Scholar, and one trial registry were searched until September 23, 2020, for studies on the use of awake proning for nonintubated COVID-19 patients. Published or in-press peer-reviewed randomized control trials, case-control trials, and prospective or retrospective cohort studies in English language only were sought, assessing the effectiveness of awake proning for nonintubated patients diagnosed with COVID-19. We included 21 published studies (19 single arm and 2 with comparison group). Twenty-three registered clinical trials were identified. No randomized clinical trial has been published so far. Awake proning is probably safe and effective in enhancing oxygenation in nonintubated COVID-19 patients; however, there is insufficient evidence. Further high-quality clinical trials are urgently needed to assess the effectiveness of awake proning on a variety of patient-centered outcomes. Parashar S, Karthik AR, Gupta R, Malviya D.
