Post Intensive Care Syndrome (PICS)

COVID-19 Related:



New or worsening cognitive, physical and/or
mental health impairments after acute care for critical illness
are referred to as “post-intensive care syndrome” (PICS). Little is known about the incidence of its components, since it is challenging to recruit patients after intensive care unit (ICU) treatment for observational studies. Claims data are particularly suited to achieve incidence estimates in difficult-to-recruit
groups. However, some limitations remain when using claims
data for empirical research on the outcome of ICU treatment.
The objective of this article is to describe three challenges and
possible solutions for the estimation of the incidence of PICS
based on claims data.
