Healthcare Process Modelling by Rule-Based Networks

Explore how medical rules and network structures are used to predict and recommend treatments based on patient health status. This study involves generating rules from historical data, converting them into network structures, and classifying health statuses. Treatment recommendations are made based on similarity and association rules. Retrieve candidate treatments and filter based on classification to recommend potential choices for doctors.

  2. Table of contents • Health status monitoring • Treatment recommendation

  3. Health Status Monitoring If x1=1 and x2=1 then y=1 • A set of medical rules used to predict health status is generated by a rule generation algorithm learning historical data and then converted into network structure illustrated inFigure 1 • Each node in input layer represents a medical feature • Each node in middle layer represents a medical rule • The output node represents the classification of health status, e.g. in risk or health input conjunction output Figure 1

  4. TreatmentRecommendation • To classify patients into a particular category based on similarity using K Nearest Neighbour. • To retrieve treatments that have been applied to previous patients classified into the same category as the currentpatient and find a list of candidate treatments by majority voting. • To classify these candidate treatments to one of rate scale of 1 to k and filter those treatments with negative classification. • To induce a list of association rules which have patient features on left hand side and medical features on right hand side and is represented by a network as illustrated inFigure 2. • To retrieve a list of most potential treatments that match the features represented by the right hand sides of association rules in order to recommend doctors a list of candidate choices.
