Persistent critical illness acquired morbidities have been well known to affect adults since our attention was drawn to this in the landmark publication by Herridge et al. in 2003. What was first labelled as intensive care unit-acquired weakness, was broadened as we began to understand the physical, neurocognitive, and psychological sequelae that can affect not only patients, but their caregivers. The Post-Intensive Care Syndrome (PICS) was coined in a 2012 publication, to capture the three key affected domains of mental health, cognitive function and physical sequalae that adult survivors experience (Needham et al. 2012). This understanding of long-term impact of critical illness on patients has prompted clinicians and researchers to expand our focus beyond acute care and survival, to optimising survivorship and longer-term functional and health-related quality of life (HRQL) outcomes in our patients and families.
