Abstract

Introduction: Using neural networks and genetic algorithms in evaluating health-related 
variables has increased recently. Employing intelligent tools for diagnosis and treatment of 
diseases can reduce medical errors and human and financial losses. In this paper, medical 
applications of neural networks have been studied in order to help both medical and artificial 
intelligence researchers. 
Methods: We used an existing sample in SPSS (patient_los.sav). The sample consisted of 
patients who received treatment for heart disease. Multilayer perceptron (MLP) was employed to 
build a neural network to predict the cost and length of treatment. Duration of hospitalization and 
treatment cost were considered as dependent variables. Other variables were entered into the 
model as agents or factors. 
Results: Neural networks can evaluate the outcomes of patients who have or have not undergone 
surgery. Separate networks can then be used to predict treatment and hospitalization costs and 
duration provided that the patients who had surgery had been identified. 
Conclusion: Neural networks designed in this paper can well forecast the usual outcomes of 
patients. Multilayer neural networks can precisely identify patients who would die after surgery. 
Non-linear properties of neural networks can help in modeling and forecasting.
