According to the World Health Organization, studies have reported that 10-20% of COVID-19 patients will go on to develop long COVID*.

Research is still on the way to identify long COVID and gathering deeper understanding of the natural history of this disease, alongside its management and longer-term sequelae. However, these efforts will not be complete without capturing patients’ experience and the disease impact on their quality of life which can be measured through Patient-Reported Outcomes (PROs).

This webinar aims to further understand long COVID assessments regarding PRO instruments and the concepts that have been researched.

The speakers will share their findings on Patient-Reported Outcomes (PROs) from ePROVIDETM databases,, and Medline, to identify PRO instruments developed for and used in long COVID. Among 156 PRO instruments developed for COVID-19, identified in the PROQOLIDTM database, only a small number were specific for long COVID (8 PROs). This was also observed in published and on-going long COVID studies. As so few PROs are developed specifically for use in long COVID patients, many generic instruments and other disease-specific instruments were used in the clinical trials such as the EuroQoL 5-Dimension (EQ-5D), the SF-36 Health Survey (SF-36), the Hospital Anxiety and Depression Scale (HADS) or the Modified Medical Research Council Dyspnea Scale (mMRC).

The use of PROs is essential in assessing the impact of long COVID on patient’s quality of life and to facilitate the research and development of treatments. This webinar aims to discuss the potential need of further research to develop disease-specific PROs for the assessment of long COVID. Mapi Research Trust COA experts can help identify the gaps or assist in the selection of fit-for-purpose PRO instruments in any therapeutic indications. The ePROVIDETM platform and COA databases are valuable resources for researchers who are preparing clinical trials in long COVID.
