Is Invasive ICU-treatment Associated With Mental Illness?

Understanding long-term complications after intensive care is important to be able to offer prophylactic and therapeutic measures to post-intensive care unit (ICU) patients. Since patients in the ICU experience life threatening conditions, severe psychological and physical stress, we hypothesized that patients after ICU have an increased risk of mental illnesses specifically anxiety disorders, depression and post-traumatic stress disorder (PTSD). Moreover, we hypothesized that the prevalence and severity of mental illnesses are related to the extent of intensive care. Our endpoints are the prevalence of anxiety disorders, depression one year after ICU-care and if the extent of intensive care an independent predictor of psychiatric illness one year after ICU admission. We will assess Swedish Intensive Care registry data for all adult ICU patients admitted between 2010-2015 and assess ICD-10 codes for anxiety disorders, depression and PTSD one year after ICU admission.
