Effectiveness of an Ontology-based  Decision Support System in the Glycemic Control Use Case

Uribe, G. A., D. M. López, B. Blobel and A. A. Ruiz. "Effectiveness of an Ontology-based  Decision Support System in the Glycemic Control Use Case ". In preparation.

37

Pilot Experiment

  • Controls the execution of the healthcare process according to policies and national medical guidelines and organizational protocols.

  • Supports the actors in the decision making process.

  • Maps the information considering the heterogeneous qualities of the actors.

The software provides interoperability at least in the following three ways:

Pilot Experiment Design

39

Pilot Experiment  - Hypothesis

The efficiency of the system's recommendation, measured through the F-measure, is higher than 0.71 using as gold standard the suggestions provided by an internist.

The threshold of 0.71 corresponds with the F-measure average of the algorithms C4.5 and CART evaluated for the diagnosis of diabetes

Results - One-Sample Test Significance

46

Results Discussion

  • In order to improve even more the F-measure is possible to add the entities and rules corresponding with the diabetic complications and all the related findings.

  • Two special diagnoses found by the doctor are “No chronic complications” and “Uncomplicated diverticular disease colon” because correspond with the absence of one medical condition.

Conclusions

48

Hypothesis

By using an architectural-centric approach to analyze, design and implement health information systems based on the Generic Component Model (GCM) and representing the components through ontologies it is possible to achieve cross-domain interoperability of health information systems supporting the diabetes care.

General Conclusion

A health information system was developed using the GCM demonstrating, in the glycemic control use case, the cross-domain interoperability of the medical, policy and resource domains. Also supports the interoperability by: policies and guidelines, decision support and knowledge mapping.

49

Other Conclusions

  • Using the GCM principles enables comprehensive interoperability

  • The consideration of the top-domain and standardized ontologies facilitates the harmonization between the different domains

  • The level of generality used in the generic description facilitates the adaptive nature of the system and the components re-usability

  • The methodology and models used facilitate the inter-disciplinary communication and allows the development of systems taking into account the experts’ knowledge and relevant policies.

Future Work

  • Improve the system evaluation
  • Implement the data models mapping
  • Implement the automatic language transformation
  • Automate the planner composer and service discovery
  • Development of a framework for the proposed development process
