Objective:
To investigate the Barthel Index (BI) score in predicting the 1-month and 1-year prognosis after discharge.
Methods:
This was a retrospective observational single-center study. We retrospectively enrolled consecutive inpatients aged ≥ 75 years from a large public hospital. Information of the basic demographic variables, BI score, disease burden, length of hospital stay, medical cost and outcomes of patients were collected. Then we analyzed the association between BI score and clinical outcomes.
Results:
A total of 242 subjects were included in this study. The median of BI score was 40 (5, 70). There were 48.76% and 82.23% patients with poor prognosis within 1 month and 1 year after discharge. BI remained an independent predictor of poor outcome within 1 month (P < 0.001) and 1 year (P = 0.027) after adjusting other factors. BI score was negatively correlated with poor outcomes. The calibration of 1-year outcomes was better than that of 1-month outcomes. The ROC analysis showed the AUC of the BI in predicting 1-month and 1-year outcomes were 0.860(P < 0.001) and 0.674(P < 0.001) respectively. The cutoff values for BI to predict 1-month and 1-year outcomes were 42.5 and 52.5.
Conclusions:
The BI score at admission was an useful predictor of outcomes within 1 month and 1 year after discharge for very elderly multimorbidity inpatients.
