[Objective] This paper uses the deep learning method to predict possible readmissions of patients based on their electronic medical records, aiming to improve hospital management. [Methods] We proposed a model based on character-level convolution neural network to process the unstructured texts. Then, with the help of structured data (demographics, clinical records and administrative data) to predict the hospital readmission cases. [Results] The deep learning model combining structured and unstructured data yielded better prediction results at F1-score of 0.735. Compared with the models only using structured or unstructured data, the F1-score was increased by 12.9% and 2.1%, respectively. [Limitations] The experimental medical records were collected from one hospital, which has some impacts on prediction results. [Conclusions] The proposed model provides references for researchers of hospital readmission prediction and hospital administrators.
