Summary
# Editorial Summary Veterinary fitness assessments at FEI competitions rely on subjective clinical evaluation by Veterinary Delegates, yet considerable variation exists between assessors when determining whether horses are fit-to-compete—a situation the authors sought to quantify by comparing inter- and intra-observer agreement with objective gait analysis data. Three experienced FEI Veterinary Delegates and one specialist evaluated twelve horses during live inspection and later from video recordings, whilst simultaneous quantitative gait analysis captured motion symmetry measurements. Fair inter-observer agreement was demonstrated during live assessments (κ = 0.395, 58% concordance), though individual assessors showed stronger consistency when re-evaluating video evidence at one and twelve months (71% and 73% agreement respectively), suggesting that subjective evaluation becomes more reliable with temporal separation from the live setting. Quantitative gait analysis achieved 83.3% sensitivity and 66.7% specificity for identifying motion asymmetry when compared against collective observer consensus, indicating moderate utility as an objective reference point. The findings propose that utilising multiple assessors concurrently or incorporating instrumented gait data alongside clinical judgement could substantiate fit-to-compete decisions, potentially reducing the inconsistency that currently characterises FEI inspections—a consideration of particular relevance given that subjective assessment alone appears insufficient as a standalone diagnostic tool for detecting performance-limiting lameness or movement dysfunction.

Practical Takeaways
- •Multiple veterinary delegates should evaluate horses for competition clearance, as individual assessments show poor inter-observer reliability that could lead to inconsistent decisions
- •Quantitative gait analysis can provide objective support to subjective fit-to-compete judgements and may improve decision consistency at competitions
- •Video recording of veterinary inspections improves consistency of individual assessor decisions over time, suggesting standardization of documentation methods
Key Findings
- •Inter-observer agreement among FEI Veterinary Delegates was fair (κ = 0.395) with only 58% agreement on fit-to-compete judgement
- •Intra-observer agreement between live observations and video re-evaluations was high at 71% (1 month) and 73% (12 months)
- •Quantitative gait analysis showed 83.3% sensitivity and 66.7% specificity for motion symmetry against observer consensus
- •Subjective veterinary inspection alone demonstrates substantial inconsistency requiring objective measurement support
