重症监护病房住院时长关联规则预测模型的临床应用价值
Application and evaluation of association rule prediction model in predicting the hospitalization duration of patients at intensive care unit
摘要
Abstract
Objective To explore the clinical application value of association rule prediction model for hospitalization duration of patients at intensive care unit(ICU).Methods A total of 1 000 ICU patients included in the First Affiliated Hospital of Hebei North University information system from March 2012 to March 2024 were selected.The patients were randomly divided into a model group(n=700)and a validation group(n=300)randomly according to a ratio of 7:3.FP-Growth algorithm was used to construct the association rule prediction model for the hospitalization duration.The internal validation of the model was performed based on the baseline data of the model group by using the C-index and calibration curve.The external validation of the model was performed based on the baseline data of the model and validation groups by using ROC curve.Results The association rule prediction model showed that the probabilities of the patients with the combination of first item baseline data being hospitalized for 1,2,3 and 4 weeks were 69.00％,43.00％,22.00％,and 8.00％,respectively.The C-index of the association rule prediction model was 0.727-0.872,which showed good consistency.The ROC for the hospitalization duration predicted by the association rule model for the patients in the model and validation groups fitted well(all P＞0.05),and their differences in AUC were not statistically significant(all P＞0.05).Conclusion The association rule prediction model constructed by the research has certain application value in predicting the hospitalization duration of ICU patients,and its prediction results can provide references for optimizing ICU medical resource allocation.关键词
