Logical Rules and a Preliminary Prototype for Translating Mortality Coding Rules from ICD-10 to ICD-11.

Area of Science:

• Medical Informatics
• Public Health Surveillance
• Health Information Systems

Background:

• The Iris system currently codes multiple causes of death using the International Classification of Diseases, 10th Revision (ICD-10).
• Transitioning to the International Classification of Diseases, 11th Revision (ICD-11) necessitates the adaptation of existing coding rules.
• Accurate cause-of-death coding is crucial for mortality statistics and public health.

Purpose of the Study:

• To evaluate the feasibility of transitioning the Iris system's rule base from ICD-10 to ICD-11.
• To analyze the logical meta-rules required for translating ICD-10 coding rules to ICD-11.
• To develop a prototype support system for experts involved in rule translation.

Main Methods:

• Analysis of logical meta-rules for rule translation.
• Development of a prototype expert support system.
• Feasibility assessment of the ICD-11 transition for cause-of-death coding rules.

Main Results:

• Identified the logical meta-rules essential for translating ICD-10 coding rules to ICD-11.
• Developed a functional prototype system to aid experts in the rule translation process.
• Demonstrated the feasibility of adapting the Iris system for ICD-11.

Conclusions:

• The transition of the Iris system's coding rules to ICD-11 is feasible.
• A structured approach involving meta-rule analysis and expert support systems is effective for this transition.
• This work facilitates the future adoption of ICD-11 for cause-of-death coding.
