COVID-19 pandemic elicited broad medical, economic, and social consequences. There is limited research and outstanding data gaps related to understanding the impact of long-term effect of COVID-19 on Health-Related Quality of Life (HRQoL) and Work Productivity and Activity Impairment (WPAI) in the outpatient settings in the US.
Information on the evolution of recovery of daily function and the return to the level of health enjoyed by outpatients prior to SARS-CoV-2 infection will inform the overall estimation of the benefits of vaccines (quality-adjusted life years [QALYs] and indirect cost saving) in COVID-19 health economics models.
