Leaving the Walkman and ICD-9 Behind: Modernizing the Disease Classification System Used by Canadian Physicians

Area of Science:

• Health Informatics
• Medical Classification Systems
• Healthcare Administration

Background:

• The International Classification of Diseases, Ninth Revision (ICD-9) was implemented in Canada in 1979.
• ICD-9 is increasingly inadequate for current healthcare demands and patient complexity.
• Modern healthcare environments require more sophisticated classification tools.

Purpose of the Study:

• To identify the limitations of the current ICD-9 system based on user feedback.
• To gather requirements for a new or updated disease classification system.
• To understand the needs of Canadian healthcare professionals regarding classification.

Main Methods:

• A survey was conducted among various ICD-9 users in Canada.
• Participants included family physicians, researchers, and decision-makers.
• The survey focused on user-identified limitations and desired features.

Main Results:

• Users highlighted significant limitations of the ICD-9 system.
• Specific features for an improved classification system were detailed.
• Feedback indicated a clear need for an updated system.

Conclusions:

• The ICD-9 classification system presents notable challenges for Canadian healthcare professionals.
• There is a strong demand for a modernized classification system that better reflects current medical practice and patient needs.
• User input is crucial for developing effective future classification systems.
