Summary
A preliminary 21-question Canine Orthopedic Index (COI) was developed for owner-completed outcome assessment in dogs with orthopedic disease, including osteoarthritis. This tool is ready for further psychometric testing.
Area of Science:
- Veterinary Medicine
- Canine Health
- Orthopedic Research
Background:
- Orthopedic diseases are common in dogs, impacting their quality of life.
- Owner-completed assessments are valuable for monitoring treatment outcomes.
- Existing instruments may not fully capture the nuances of canine orthopedic conditions.
Purpose of the Study:
- To develop a reliable owner-completed outcome assessment instrument for dogs with orthopedic disease.
- To create a preliminary version of the Canine Orthopedic Index (COI).
Main Methods:
- Utilized focus groups and key-informant interviews with owners of dogs with osteoarthritis (OA).
- Analyzed discussed behaviors using descriptive statistics, discrimination analysis, and frequency endorsement.
- Refined behavioral lists with veterinary experts to develop survey questions.
Main Results:
- A 21-question preliminary Canine Orthopedic Index (COI) was developed.
- No limb-specific behaviors were identified, leading to a non-limb-specific instrument.
- Four behaviors with low endorsement frequency were excluded.
Conclusions:
- A 21-question owner-completed COI was successfully developed.
- The preliminary COI is prepared for subsequent psychometric validation studies.
- This instrument aims to improve outcome assessment for canine orthopedic conditions.
