Decision trees are easy to use compared to other decision-making models, but preparing decision trees, especially large ones with many branches, are complex and time-consuming affairs. (Suppl. Zorman, M., Podgorelec, V., Kokol, P., Peterson, M., and Lane, J., Decision tree's induction strategies evaluated on a hard real world problem. The way a Decision Tree partitions the data space looking to optimize a given criteria will depend not only on the criteria itself (e.g. Decision trees are a reliable and effective decision making technique that provide high classification accuracy with a simple representation of gathered knowledge and they have been used in different areas of medical decision making.

An important distinction between CART and CTree is that the latter uses a formal statistical hypothesis testing framework in building decision trees, which simplifies the process of identifying and interpreting the final tree model.

The main limitation of decision trees is their inflexibility to model decision problems, which involve recurring events and are ongoing over time. The aim of decisional systems developed for medical life is to help physicians, by providing automated tools that offer a second opinion in decision-making process. This can be connected to the diagnosis phase, treatment option, patient's evolution, identification of special medical conditions (including those emphasized by medical images analysis), or other aspects that can support … 2020 Oct 27;10(11):873. doi: 10.3390/diagnostics10110873. Focus on decision-making has led to the development of the shared decision-making (SDM) model, in which patients and doctors share information and values, and patients play an active role in making healthcare decisions [ 6 , 7 ].

Stud Health Technol Inform. In the paper we present the basic characteristics of decision trees and the successful alternatives to the traditional induction approach with the emphasis on existing and possible future applications in medicine. Two types of decision models are introduced, decision trees and Markov models, along with a worked example of how each method is used to examine costs and health consequences. 7 Such tools may also be useful for public health policy and service delivery organisations to aid their selection of evidence‐based interventions and implementation strategies, and also to identify where further evidence needs to be generated. Here, we give an overview of the rationale for the use of patient decision aids, what they contain, the evidence of their efficacy, and examples of their current and potential uses.
