Coverage of Physical Therapy Assessments in the Observational Medical Outcomes Partnership Common Data Model

Area of Science:

• Health informatics
• Rehabilitation science
• Clinical data standardization

Background:

• High-value care emphasizes meaningful patient outcomes and cost reduction.
• Common Data Models (CDMs) like Observational Medical Outcomes Partnership (OMOP) facilitate data curation across healthcare systems.
• Incorporating physical function assessments into CDMs is crucial for measuring meaningful outcomes.

Purpose of the Study:

• To evaluate the coverage of physical therapy assessments for neurologic and orthopaedic conditions within the OMOP CDM.
• To identify the extent to which these assessments are represented in the OMOP CDM.

Main Methods:

• Identification of relevant physical therapy assessments for neurologic and orthopaedic conditions.
• Independent mapping of identified assessments into the OMOP CDM by two reviewer teams.
• Assessment of inter-reviewer agreement and reconciliation of disagreements.
• Analysis of the number of concept ID numbers associated with each mapped assessment.

Main Results:

• Approximately 47-48% of neurologic and orthopaedic physical therapy assessments were successfully mapped into the OMOP CDM after reconciliation.
• A significant portion of assessments (around 42-52%) remained unmapped.
• Mapped assessments frequently involved multiple concept ID numbers, indicating potential complexity in data representation (average 2.2 for neurologic, 4.3 for orthopaedic).

Conclusions:

• The OMOP CDM currently offers partial coverage for physical therapy assessments in neurologic and orthopaedic care.
• The presence of multiple concept IDs for mapped assessments highlights challenges in standardized data representation.
• Recommendations include expanding the OMOP CDM with more functional assessments and developing clear mapping guidelines to improve the inclusion of functional data.
