Post-COVID Condition Core Outcomes

ROUND 2 iS OPEN until THURSDAY (23:59 GMT), 4 November, 2021
PC-COS Project
The Coronavirus disease 2019 (COVID-19) pandemic has necessitated rapid responses from healthcare systems and research networks all over the world. The post-COVID-19 condition, also known as Long-COVID-19 is becoming an important target for research and clinical practice. With an increasing number of studies assessing sequelae of COVID-19, there is a need for a standardised evaluation and reporting of outcomes.

PC-COS project is an international consensus study to develop a standardised set of outcomes – a ‘core outcome set’ (COS) – to be used by all future trials examining outcomes and clinical practice in people with the post-COVID condition.

The project is designed by a group of international experts and members of the public, including people with lived experience of the post-COVID condition, and is supported by WHO.
