RESUMO
BACKGROUND AND PURPOSE: Mobilization of critical patients should be precocious and the inclusion of nursing in this task can be decisive in paradigm shift. The purpose of this study was to validate the Portuguese version of the intensive care unit Mobility Scale for nursing use. METHODS: Prospective multicenter observational study. Patients' mobility was evaluated by rehabilitation nurses in order to determine interobserver agreement. The validation criteria was tested by determining the correlation between the evaluation results of mobility, strength, and functionality levels at discharge. RESULTS: Good interobserver agreement (R = 0.98; K = 0.76). Positive correlation with muscle strength (R = 0.77) and functionality (R = 0.85) levels at discharge. CONCLUSIONS: Based on the correlations observed the scale is a valid instrument for nurses and could be a useful tool for routine use. More research is recommended to make the results more robust.
