Condition/Diagnosis/Health Issue/Problems/Findings Modeling Options

“CONTEXT” OF FINDINGS

General Assumption About Finding

• The purpose of finding model is to describe something that exists or is true (a diagnosis, a condition, a finding) about a person

• The finding can be highly pre coordinated or post coordinated. It has substructure that depends on the kind of thing that is being represented

• The finding model gets reused in many different contexts: Health Issue (Problem), Family History, Complication, Reason for Admission, Surgery Complication, Final Discharge Diagnosis, Finding, etc.

Finding as part of Health Issue

Note: This strategy could lead to “combinatorial explosion.”

Some conclusions and a proposal

• There will be many qualifiers that are used in different subsets of findings

• We have a previously stated preference for “the most reasonable post coordinated approach”

• We should follow the post coordinated approach for our “preferred” models for interoperability

• Precoordinated models will be useful for data entry and other use cases
