Critical Matters

Recovering after a stay in the intensive care unit (ICU) is a long and difficult process, and for some survivors, healing the body may only be a fraction of the journey.
In recent years, attention has increasingly turned to the cognitive impact post-intensive care syndrome, or PICS, has on ICU patients. In this episode of Critical Matters, Dr. Sergio Zanotti explores how to communicate with patients and families about post-intensive care syndrome.
He is joined by Dr. Carla M. Sevin, an Associate Professor of Medicine in the Division of Allergy, Pulmonary, and Critical Care Medicine at Vanderbilt University Medical Center (VUMC). Dr. Sevin also serves as Director of the Pulmonary Patient Care Center and Director of the ICU Recovery Center.
