The patients were randomized 3:1 to the training and validation sets. The risk factors for hypoglycemia were analyzed. A prediction model was developed.Results: This study included 122 patients, and 57 patients had at least one hypoglycemic event during their hospitalization (46.72%). The multivariable logistic regression analysis showed that the time to reach the glycemic targets (odds ratio (OR)=1.408, 95% confidence interval (CI)=1.084– 1.825, P=0.006), average glycemia (OR=0.387, 95% CI=0.233– 0.643, P=0.010), coronary heart disease (OR=0.089, 95% CI=0.016– 0.497, P< 0.001), and the administration of hormone therapy (OR=6.807, 95% CI=1.128– 41.081, P=0.037) were independently associated with hypoglycemia. A nomogram was built. The receiver operating characteristics analysis showed that the area under the curve of the model was 0.872 (95% CI=0.0.803– 0.940) for the training set and 0.839 (95% CI=0.688– 0.991) in the validation set.Conclusion: A nomogram was successfully built to predict hypoglycemia in T2DM patients treated with an insulin pump during enteral nutrition, based on the time to reach the glycemic targets, average glycemia, coronary heart disease, and the administration of hormone therapy.Keywords: T2DM, hypoglycemia, enteral nutrition, insulin pump therapy, nomograms
