Summary
# Editorial Summary Between 2000 and 2013, researchers analysed all veterinary incidents recorded across National Hunt flat races in Great Britain, identifying 544 events over approximately 42,000 starts and examining which factors increased the risk of fatal outcomes. Bone injuries were the most prevalent veterinary event (23.5% of cases), followed by tendon and ligament injuries (16.4%), with an overall incidence of 13.0 veterinary events per 1000 starts and 2.9 fatalities per 1000 starts. Two significant risk factors emerged: races restricted to conditional jockeys carried 4.33 times higher odds of fatality than unrestricted races, whilst horses competing in their first race faced 1.44 times greater odds of death compared to experienced racers. These findings provide concrete evidence to support discontinuing conditional-jockey-only races and underscore the vulnerability of debut runners, suggesting that either inadequate conditioning, inconsistent ridden experience, or a combination thereof warrants urgent investigation to reduce preventable deaths. For practitioners involved in pre-race assessment and conditioning, these results emphasise the critical importance of rigorous preparation protocols for first-time runners and highlight that race structuring decisions have measurable welfare consequences.

Practical Takeaways
- •Phasing out National Hunt flat races restricted to conditional jockeys may reduce fatality risk, as these races showed significantly higher mortality rates
- •First-time racehorses in NH flat racing are at elevated risk of fatal injury; additional pre-racing conditioning, veterinary screening, or race restrictions for debut runners should be considered
- •Bone and soft tissue injuries dominate veterinary events in this discipline; practitioners should focus surveillance and preventive strategies on these injury types
Key Findings
- •Overall incidence of veterinary events was 13.0 per 1000 starts over 14 years, with bone injuries (23.5%) and tendon/ligament injuries (16.4%) being most common
- •Fatality occurred in 21.5% of all veterinary events (117 horses), representing 2.9 deaths per 1000 starts
- •Races restricted to conditional jockeys had 4.33 times higher odds of fatality compared to unrestricted races
- •First-time racing Thoroughbreds experienced 1.44 times higher odds of death compared to experienced racehorses
