Description
Summary:Abstract Purpose The purpose of this study was to determine the interrater reliability of the Perme Intensive Care Unit Mobility Score. Materials and methods This was a prospective observational study. Data were collected from 20 patients admitted in a cardiovascular intensive care unit. The interrater reliability was tested using the intraclass correlation coefficient with 95% confidence interval and the Cohen κ coefficient of 0.9, using a 2-tailed α of .05 to provide a 90% power. Results The 15 items of the Perme ICU Mobility Score were individually analyzed. Interrater reliability (Cohen κ coefficient) for items 2, 3, 5, 6, 7, 8, 13, and 15 was 1.0000; for item 1, 0.8276; item 4, 0.8000; item 9, 0.6000; item 10, 0.7297; item 11, 0.7260; item 12, 0.7872; and item 14, 0.9048; the intraclass correlation coefficient (95% confidence interval) was 0.9880 (0.97743-0.99859). Conclusions The Perme ICU Mobility Score is a reliable tool to assess mobility status of patients admitted to the cardiovascular intensive care unit in a specific moment in time, which can be an important tool for research and clinical practice.
