I-MOVE: Inpatient pre-discharge mobility score as a predictor of post-discharge mortality

• Objective: To determine whether a score of 8 or greater on the I-MOVE, a bedside instrument that evaluates the need for assistance in turning, sitting, standing, transferring from bed to a chair, and ambulating, predicts lower risk for 30-day readmission or mortality. • Design: Retrospective cohort study of patients discharged from 2003 to 2011 from a referral hospital in Southeastern Minnesota. We used a convenience sample of 426 inpatients who had at least one documented calculation of the I-MOVE score performed as part of the clinical process during the study. • Results: Overall 30-day mortality rate, readmission rate, and rate of the combined death/readmission outcome were 6.1% (26 patients), 15% (64 patients) and 19.7% (84 patients), respectively. After controlling for confounding variables, an I-MOVE score ≥ 8 was a significant predictive factor for 30-day mortality (OR = 0.136, P < 0.01) but not 30-day readmission (OR = 1.143, P = 0.62) or the combined outcome death/readmission (OR = 0.682, P = 0.13). • Conclusion: The clinical information provided by a patient's I-MOVE score before discharge does not provide information about readmission risk but may offer incremental information about 30-day mortality risk.
