In this paper, an analysis is presented of one of the quality indicators: the rate of return of patients to the emergency service less than 72 h from their discharge. The objective of the analysis was to know the variables that influence the rate of return and which prediction model is the best. In order to do this, the data of the activity of the emergency service of a hospital of a reference population of 290,000 inhabitants were analyzed, and prediction models were created for the binary objective variable (rate of return to emergencies) using the logistic regression techniques, neural networks, random forest, gradient boosting and assembly models. Each of the models was analyzed and the result shows that the best model is achieved through a neural network with activation function tanh, algorithm levmar and three nodes in the hidden layer. This model obtains the lowest mean squared error (MSE) and the best area under the curve (AUC) with respect to the rest of the models used. eng Atribución 3.0 España Application of Machine Learning Techniques to Analyze Patient Returns to the Emergency Department journal article URL https://docta.ucm.es/bitstreams/3f1356cf-456b-4bc2-8b4d-d19de1d518e4/download File MD5 2515d64b5ae752855a26121e84789b11 1205254 application/pdf jpm-10-00081-v2.pdf
