Abstract
Background
Long-term physical dysfunction common among intensive care unit (ICU) survivors and mortality remains a concern even after hospital discharge. Although early identification of patients at risk for these outcomes is essential, few studies have investigated whether physical assessments at ICU discharge can predict physical dysfunction or death at 3, 6, and 12 months after discharge. The purpose of this study was to examine the association between physical assessment at ICU discharge and the incidence of physical functional disability or death within 12 months after discharge.
Methods
This was a multicenter prospective cohort study of 21 ICUs in Japan. Patients with sepsis admitted to the ICU for >48 h were enrolled. The primary outcome was physical dysfunction (Barthel index ≤90) or death at 3, 6, and 12 months after discharge. Physical assessments at the time of ICU discharge included the Medical Research Council (MRC) score, handgrip strength, and the Barthel index. A multiple logistic regression model and area under the curve (AUC) were used.
Results
In total, 300 ICU patients (median age, 74 years) were included. MRC score (odds ratio [OR]: 0.98, 95% confidence interval [CI]: 0.96-0.99, cut-off: 46), hand grip strength (OR: 0.95, 95%CI: 0.92-0.98, cut-off: 12.0 kg), and Barthel index (OR: 0.96, 95%CI 0.95-0.98, cut-off: 15) were independent predictors of physical dysfunction or death at 12 months after hospital discharge and at 3 and 6 months. The Barthel index at ICU discharge showed the highest AUC for physical function or death at 12 months (0.718). The Barthel index and hand grip strength were also associated with cognitive dysfunction or mental disorders.
Conclusions
In ICU patients with sepsis, clinically available physical and muscle strength assessments at ICU discharge were significantly associated with physical dysfunction incidence or death over the first year of hospital discharge.
