Data mining techniques utilizing latent class models to evaluate emergency department revisits

• Data mining techniques can be applied to repeat users of emergency department care. • Information integrated from distributed sources enabled four Hidden Markov Models. • Integrating pre-analysis of HMMs yielded better predictions. The use of machine learning techniques is especially pertinent to the composite and challenging conditions of emergency departments (EDs). Repeat ED visits (i.e. revisits) are an example of potentially inappropriate...
