The study has a retrospective and a prospective component. The retrospective component aims to review data of all airway management related SAEs in COVID 19 patients (between April and July 2020); hypoxemia, hypotension and cardiac arrest within 15 min of intubation. The prospective component aims to assess the incidence of COVID-19 infection in Airway Management Team members by means of an interview assessing their COVID19 status after participating in airway management in the period outlined above. This prospective interview component is starting in December 2020.

Approximately 5-10% of all patients affected by COVID-19 develop severe respiratory distress. This has already involved hundreds of people in Ontario and thousands worldwide. In this situation, support with a mechanical ventilator is required. The first essential step to provide this support is to insert a breathing tube in the patent's trachea (windpipe), a process called 'endotracheal intubation' or more broadly, 'airway management'. While a fundamental lifesaving resource, endotracheal intubation in COVID-19 patents is a highly specialized procedure that carries risk both to patents and attending healthcare providers as follows. a) Clinicians involved in airway management for patients with coronaviruses are at extremely high risk of infection due to aerosol and droplet exposure during the procedure. b) Rapid administration of drugs that put the patent to sleep is usually required for prompt and safe endotracheal intubation. However, in physiologically compromised patents, life-threatening side-effects may occur, such as very low oxygen levels (in as many as 70% of patients), low blood pressure (18-22% of patients), and cardiac arrest (2%); these can significantly affect outcomes. No definitive data are presently available to accurately quantify the risk posed by such procedures to healthcare professionals and patents, nor the associated factors. We have developed a retrospective study reviewing data all airway management related SAEs in COVID 19 patients (between April and July 2020); hypoxemia, hypotension and cardiac arrest within 15 min of intubation. Additionally, we are going to prospectively interview Airway Management Team members that were involved in the airway management of COVID19 patients in the period described above, in order to assess whether they developed signs and symptoms and/or a confirmed COVID19 infection. This prospective interview component is starting in December 2020.

Inclusion Criteria:

All Suspected or confirmed Covid-19 patients that require intubation Health care workers from the airways management team who performed an intubation on confirmed or suspected Covid-19 patients

Exclusion Criteria:

Lack of Health Care Provider Consent

The study will use exclusively retrospective data from suspected or positive COVID-19 adult patients who required intubation during their hospital stay and also record the rate of infection in HCP who perform the intubation.
