Abstract

Post Intensive Care Syndrome (PICS) encompasses new or worsening cognitive, mental, or physical health impairments following an admission to an intensive care unit (ICU). Older adults who survive ICU are at increased risk for PICS. The number of older adults admitted to ICUs is increasing, with over 50% of Canadian ICU patients being over the age of 65 in 2014, and similar statistics observed during the COVID-19 pandemic. The anticipated corresponding increase in PICS prevalence has important implications for ICU survivors, their families, and our healthcare system. Currently, family physicians manage the majority of post-hospital care for ICU survivors in Canada. This article provides family physicians with a pragmatic approach to the diagnosis and management of cognitive impairment in older adults following an admission to ICU.
