The Jockey Club releases injury data

Last updated: 12/15/10 10:53 AM

On Wednesday, The Jockey Club released an updated North American fatality

rate for Thoroughbreds that includes two years' worth of data in the Equine

Injury Database, the North American database for racing injuries. The Jockey

Club launched the database during the summer of 2008.

Based on an analysis of 754,932 starts collected during the two-year period

November 1, 2008, through October 31, 2010, the prevalence of fatal injury

declined to 2.00 per 1,000 starts, as compared to the 2.04 rate reported in

March for the one-year period November 1, 2008, through October 31, 2009.

The analysis was performed by Dr. Tim Parkin, a veterinarian and

epidemiologist from the University of Glasgow, who serves as a consultant on the

Equine Injury Database.

Parkin noted that the change in the overall fatality rate stemmed from

cumulative two-year data that revealed a statistically significant difference in

the prevalence of fatality on both turf and synthetic surfaces versus dirt. The

difference in the prevalence of fatality between synthetic and turf surfaces was

not statistically significant.

"The addition of 376,000 starts to the database in year two enabled us to

statistically validate certain trends seen in the data," Parkin explained.

"Trends will continue to emerge and evolve as additional data becomes available

for study and as more complex statistical analyses are performed. This will

allow us to understand how different variables, alone and in concert, may impact

the risk of fatality."

Among other trends gleaned from Parkin's analysis of the cumulative two-year

data:

  • The prevalence of fatality in two-year-olds continued to be

    significantly lower than older horses racing on dirt surfaces. However, on

    synthetic or turf surfaces, there was no statistically significant

    difference in the prevalence of fatality between two-year-olds and older

    horses.

  • The prevalence of fatality continued to be unaffected by distance,

    weight carried and movement of races off the turf.

  • Fillies and mares competing in races that were open to horses of all

    sexes were not at an increased risk of fatality compared to those competing

    in races restricted to fillies and mares.

  • The following table presents the comparable fatality rates by surface type

    for the one-year and cumulative two-year periods beginning November 1, 2008.

    Thoroughbred Fatality Rate per

    1,000 Starts by Surface

    and Reporting Period

    Surface Type November 1, 2008-

    October 31, 2009

     November 1, 2008-

    October 31, 2010

    All 2.04 2.00
    Dirt 2.14 2.14
    Synthetic 1.78 1.55
    Turf 1.78 1.74

    "We will continue to publish these national benchmarks on an annual basis to

    provide the necessary statistical foundation participating racetracks need for

    monitoring and comparing their individual results," said Matt Iuliano, The

    Jockey Club's executive vice president and executive director.

    "Racetracks participating in the Equine Injury Database have an extensive

    menu of reporting tools and other resources available through the InCompass RTO

    system designed to assist management in developing safety initiatives aimed at

    reducing injuries to our equine athletes," he added. "As the database continues

    to grow, we look forward to the additional information and statistical power it

    will yield to improve the health and safety of the racehorse."

    The Jockey Club, through two of its for-profit subsidiary companies,

    InCompass and The Jockey Club Technology Services Inc., has underwritten the

    cost to develop and operate the Equine Injury Database as a service to the

    industry. By agreement with the participating racetracks, from time to time The

    Jockey Club may publish certain summary statistics from the Equine Injury

    Database, but will not provide statistics that identify specific participants,

    including racetracks, horses or persons. The Equine Injury Database contains a

    suite of reports for racetracks to analyze data collected at their respective

    facilities.

    A list of racetracks that have signed up to participate in the Equine Injury

    Database may be found at
