Using the EuroQol-5D to measure changes in quality of life 12 months after discharge from an intensive care unit

Abstract
Objective: To compare changes in the health-related quality of life (HRQOL) of critical care patients by diagnostic category. Design: Prospective, cohort study. HRQOL assessed 3 months before admission and 1 year after discharge from the intensive care unit (ICU). Patients were classified as: trauma injury (TI), scheduled surgery (SS), unscheduled surgery (US), and other medical conditions (MC). Setting: Department of Intensive Medicine, University Hospital of Bellvitge, Barcelona, Spain. Patients: Three hundred and thirty-four patients admitted to ICU from October 1994 to June 1995 (62 TI patients, 181 SS patients, 19 US patients, and 72 MC patients). Interventions: Surgical and medical procedures. Measurements and results: Changes in HRQOL varied considerably between diagnostic categories, with TI patients having significantly worse HRQOL one year after discharge from the ICU compared to 3 months prior to admission [change in median EQ Visual Analogue Scale (EQ-VAS) score from 100 to 65, PPConclusions: The degree and direction of change in ICU patients' HRQOL 1 year after discharge depends considerably on diagnostic category. Proxy responses can be reliably used with the EQ-5D when measuring change in HRQOL.
