Abstract:

Objective

To analyze the incidence, occurrence time and risk factors of cholestasis in the elderly patients after long-term jejunal feeding, and to construct a risk prediction model for cholestasis in the elderly patients after long-term jejunal feeding.

Methods

Clinical data of 84 the elderly patients over 65 years of age who were hospitalized in the Second Medical Center of PLA General Hospital from July 2019 to July 2022 and underwent jejunal nutrition tube insertion more than 2 weeks after surgery were retrospectively collected. The patients were divided into two groups according to whether cholestasis occurred. The incidence of cholestasis was analyzed. In addition, univariate and multivariate analysis of related risk factors was carried out to construct the corresponding risk prediction model, and the prediction performance and clinical applicability of the model were further evaluated.

Results

A total of 84 patients were included in the study, of which 38 patients developed cholestasis, with an incidence rate of 45.2%. The median time of tube feeding was 556.5 days. Multivariate analysis showed that: Uric acid, endotracheal intubation, history of heart failure, history of Alzheimer′s disease and history of diabetes were independent risk factors for cholestasis in the elderly patients after long-term feeding in jejunal tubes. The concordance index of COX risk prediction model established based on the above risk factors was 0.78. The Calibration curve and decision curve analysis showed that the model had good predictive performance and clinical applicability.

Conclusion

The elderly patients are prone to cholestasis after jejunal tube feeding for a long time. Uric acid, tracheal intubation, history of heart failure, history of Alzheimer′s disease and history of diabetes are independent risk factors for cholestasis after jejunal tube feeding for a long time.
