Abstract
BACKGROUND Noninvasive respiratory support (NIRS) has been revealed feasible solutions to cope with the massive request for ventilatory support in patients subjected to ‘do-not-intubate’ order (DNI). OBJECTIVES The aims of the present systematic review and meta-analysis was to estimate pooled incidence of DNI orders and the associated in-hospital mortality in patients undergoing NIRS for hypoxaemic acute respiratory failure (ARF) related to coronavirus disease 2019 (COVID-19). DESIGN Systematic review of observational studies and randomized-controlled trials with meta-analyses DATA SOURCES PUBMED, EMBASE, and Cochrane Controlled Clinical trials register were searched for observational studies and randomised-controlled trials from inception to the end of April 2022. ELIGIBILITY CRITERIA Inclusion criteria were: observational studies enrolling ≥50 hospitalised patients with hypoxaemic COVID-19-related ARF requiring NIRS and DNI order application.
