Abstract: Intelligent systems and knowledge management are shown to have wide ranging applications for businesses. In healthcare, applications of expert systems and knowledge management have been popular since the use of MYCIN in the 1970s. In this research, we study the use of intelligent systems in the prediction of re-hospitalisations. A Bayesian network, an artificial neural network using multilayer perception, an artificial neural network using radial basis function, a support vector machine and an expert system (five intelligent systems) were used in the prediction. All the models except the support vector machine were able to provide good prediction of re-hospitalisation (with AUC > 0.6) and complete risk stratification for re-hospitalisation within 30 days of discharge with data available at admission, showing great promise for future application of intelligent systems in healthcare.

Keywords: knowledge management; intelligent systems; healthcare information systems; expert systems; artificial neural networks; ANNs; decision support systems; DSS; re-hospitalisation prediction; Bayesian networks; multilayer perception; radial basis function; support vector machines; SVM.
