Reduced ICU Mobility Scale scores significantly predict mortality in critically ill patients receiving mechanical ventilation

Objetivo

Enhancing critical care mobility can counter the detrimental impact of ICU-acquired weakness. Physical activity in the ICU links to illness severity and outcomes. We explored correlations between ICU mobility during mechanical ventilation (MV) and mortality rates.

Métodos

We conducted a retrospective single-center study. The study involved patients under MV from Jan-Jun 2023, admitted to the ICU due to acute respiratory failure, excluding post-surgery cases. Patients underwent daily mobility assessment using the ICU Mobility Scale (IMS). The highest IMS score during ICU stay (h-IMS) was used to categorize the patients into low (h-IMS < 4) or moderate-to-high mobility (h-IMS ≥ 4).

Resultados

We included 55 participants (50.9% women, 69.69 ± 16.74 years, SOFA score = 6,31 ± 3,51 and SAPS-3 = 57.44 ± 15.13). 58.2% mostly had low mobility, while 41.8% had moderate-to-high mobility. Subjects with low mobility had significantly longer MV duration than those with higher IMS scores (13.03 ± 12.55 versus 6.23 ± 8.55 days, respectively; p = 0.03). A significant association between death and lower h-IMS existed (rs = - 0.546, p < 0.01). A logistic regression analyzed the effects of mobility level on death likelihood in our sample. The logistic regression model was significant, suggesting that 35% of the variability in the outcome of death was accounted for h-IMS (Exp(β) = 0.64; p = 0.00).

Conclusão

The findings underscore the association between low mobility levels and increased mortality risk, establishing mobility as a crucial indicator across various metrics in the ICU for predicting unfavorable patient outcomes.
