The study, Extra Corporeal Membrane Oxygenation for 2019 novel Coronavirus Acute Respiratory Disease (COVID-19 Critical Care Consortium), is a prospective/retrospective multi-centre short period incidence observational study of intensive care unit patients with COVID-19. 

This study is being led by Asia Pacific ELSO leaders, A/Professor Gianluigi Li Bassi, Dr Jacky Suen, and Professor John Fraser in collaboration with ELSO, ISARIC, SPRINT-SARI, and more than 440 worldwide centres. 

The study’s aim and objectives are to describe clinical features, the severity of pulmonary dysfunction, ECMO technical characteristics, duration of ECMO, complications, and survival of patients with COVID-19.

The study period will comprise of a 28-day cohort study in which patients with confirmed COVID-19 infection, who are newly admitted to the hospitals/ICUs at participating sites, will be included in the study.

The study will be conducted in all collaborating hospitals or ICU-based research networks globally. All clinical information and sample data will only be recorded if taken as part of the routine clinical practice at each site and only fully anonymised and de-identified data will be submitted centrally.

For additional information or to participate in the study, please contact the study coordinators.

BASIC CRF: Designed for sites with limited resources for data collection

In response to feedback from our sites, COVID Critical recently launched a modified Case Report Form (CRF), referred to as the Basic CRF. This CRF features a significant reduction in data collection frequency, while maintaining collection of important variables to achieve research targets and analysis of clinically relevant outcomes. 

The frequency of daily data collection will be reduced from 14 days from hospital admission, on the day of ICU admission, and every day of mechanical ventilation, to a maximum of 7 non-consecutive days.


No new variables will be collected as part of the Basic CRF.

The frequency of daily data collection will be reduced from 14 days from hospital admission, on the day of ICU admission, and every day of mechanical ventilation, to a maximum of 7 non-consecutive days as per the following timepoints:
