Risk prediction model for adult intolerance to enteral nutrition feeding – A literature review

Abstract

Enteral nutrition is an important clinical nutritional supplementation method, especially for adult patients who are unable to eat normally or require additional nutritional support. However, many patients experience intolerance to enteral nutrition, such as delayed gastric emptying, bloating, and diarrhea, which not only affect the patient's nutritional status but also increase the risk of medical complications. In recent years, medical researchers have been dedicated to identifying and analyzing various factors that contribute to enteral nutrition intolerance, including the patient's disease status, nutritional formula, feeding method, and rate. In addition, research is also exploring the establishment of risk prediction models to more accurately predict which patients may develop enteral nutrition intolerance. These models typically combine clinical parameters, biomarkers, and patient individual characteristics, aiming to assist clinicians in better planning and adjusting nutritional treatment plans, thereby reducing the occurrence of intolerance events. This review summarizes the research progress on enteral nutrition intolerance in adult patients, with a focus on the latest developments in intolerance factors and risk prediction models, providing valuable guidance for clinical practice and helping improve patients' nutritional status and overall health.
