ObjectivesTo determine the influence of active mobilization during critical illness on health status in survivors 6 months post ICU admission.DesignPost hoc secondary analysis of a prospective cohort study conducted between November 2013 and March 2015.SettingTwo tertiary hospital ICU's in Victoria, Australia.PatientsOf 194 eligible patients admitted, mobility data for 186 patients were obtained. Inclusion and exclusion criteria were as per the original trial.InterventionsThe dosage of mobilization in ICU was measured by: 1) the Intensive Care Mobility Scale where a higher Intensive Care Mobility Scale level was considered a higher intensity of mobilization or 2) the number of active mobilization sessions performed during the ICU stay. The data were extracted from medical records and analyzed against Euro-quality of life-5D-5 Level version answers obtained from phone interviews with survivors 6 months following ICU admission. The primary outcome was change in health status measured by the Euro-quality of life-5D-5 Level utility score, with change in Euro-quality of life-5D-5 Level mobility domain a secondary outcome.Measurements And Main ResultsAchieving higher levels of mobilization (as per the Intensive Care Mobility Scale) was independently associated with improved outcomes at 6 months (Euro-quality of life-5D-5 Level utility score unstandardized regression coefficient [β] 0.022 [95% CI, 0.002-0.042]; p = 0.033; Euro-quality of life-5D-5 Level mobility domain β = 0.127 [CI, 0.049-0.205]; p = 0.001). Increasing the number of active mobilization sessions was not found to independently influence health status. Illness severity, total comorbidities, and admission diagnosis also independently influenced health status.ConclusionsIn critically ill survivors, achieving higher levels of mobilization, but not increasing the number of active mobilization sessions, improved health status 6 months after ICU admission.Copyright © 2021 by the Society of Critical Care Medicine and Wolters Kluwer Health, Inc.
