Summary
# Editorial Summary: Scoring Recovery Quality After Equine Anaesthesia Whilst recovery from general anaesthesia is a critical period in equine practice, the reliability of scoring systems used to assess recovery quality has never been formally validated. Vettorato and colleagues evaluated four recovery quality scoring systems (RQSSs) by having 117 final-year veterinary students score video recordings of nine horses recovering from anaesthesia using each system, with their rankings then compared against both their own initial intuitive ranking and assessments made by 12 experienced equine anaesthetists. All four systems demonstrated excellent reproducibility with interobserver variability below 4%, and strong agreement (r = 0.983) was achieved between student and expert evaluations, suggesting that recovery scoring is relatively straightforward to learn and apply consistently. The study found that approximately 80% of variation in recovery quality scores derived from genuine differences between individual horses rather than inconsistency between assessors, confirming that RQSSs can reliably discriminate between recovery trajectories. For equine professionals involved in anaesthetic management or post-operative care, this finding means that RQSS selection can now be based on practical considerations—such as ease of use in a clinical setting—rather than concerns about measurement reliability, potentially enabling more standardised multi-centre research and improved benchmarking of recovery protocols across different equine practices.

Practical Takeaways
- •Any of the four RQSSs examined can be reliably used to assess horse recovery quality from anaesthesia—choose based on what is easiest to implement in your facility
- •Recovery quality differences are primarily due to individual horse factors rather than evaluator inconsistency, so focus quality improvement efforts on perioperative management variables
- •Even less experienced evaluators produce reliable assessments comparable to expert anaesthetists, making these systems practical for multi-centre studies and routine clinical use
Key Findings
- •All 4 recovery quality scoring systems (RQSSs) demonstrated equal reliability with interobserver variability <4%
- •Differences between individual horses accounted for 80% of total variation, not differences between evaluators
- •Strong correlation (r = 0.983) existed between student rankings and experienced anaesthetist rankings
- •RQSS selection can be based on practical criteria such as ease of use rather than reliability differences
