New Study Finds Horses Racing On Lasix At 62 Percent Increased Risk Of Sudden Death

by Paulick Report Staff

 

A new study of data from the Equine Injury Database has revealed that horses medicated with furosemide (Lasix) on race day were at 62 percent increased odds of sudden death compared to horses that were not racing on furosemide.

Funded by the Grayson Jockey Club Foundation, the study was published by Dr. Euan Bennet and Dr. Tim Parkin on Oct. 20, 2022, in the Journal of the American Veterinary Medical Association. It examined the 4,198,073 race starts made by 284,387 Thoroughbred horses at 144 racetracks in the United States and Canada between 2009 and 2021; those numbers represent 92.2 percent of all official race starts during that period.

Of those nearly 4.2 million starts, 536 resulted in a horse’s sudden death, an incidence rate of 0.13/1,000 starts. Sudden death was defined as any horse that was recorded as a fatality within three days of racing, along with one or more of the following fatal injury descriptions or (presumptive) diagnosis, as provided by each participating track to the EID: (1) sudden death (recorded as “SUD” in the EID), (2) pulmonary hemorrhage, (3) exercise-induced pulmonary hemorrhage (EIPH), (4) postexertional distress/heatstroke (PED), and (5) cardiac arrhythmia.

Virtual Welfare & Safety of the Racehorse Summit Concludes with Update on the Equine Injury Database

June 9, 2020

 

The ninth Welfare and Safety of the Racehorse Summit, held this year as a series of weekly webinars due to the impact of the COVID-19 pandemic, concluded today with a presentation on findings from the Equine Injury Database. The webinars were hosted by Grayson-Jockey Club Research Foundation, which had previously hosted eight in-person summits.

This week’s presentation was delivered by Dr. Tim Parkin, professor of Veterinary Epidemiology at the University of Glasgow, and the webinar was moderated by Dr. Mary Scollay, executive director and chief operating officer of the Racing Medication & Testing Consortium. Parkin described risk factors for fatal injury in Thoroughbred racehorses based on data from the Equine Injury Database. Risk factors included history of previous industry, time spent on the vet’s list, increased age at first start, changing trainers and time spent with a trainer, track surface and condition, race distance, and racing in claiming races.

“Even though we were unable to host an in-person Welfare and Safety of the Racehorse Summit, we felt it was important to offer these webinars to inform industry stakeholders and the public on the work being done to protect our equine athletes and enhance equine welfare,” said Jamie Haydon, president of Grayson. “We thank our presenters and moderators for taking the time to discuss the important work they are doing to protect equine athletes.”

Today’s webinar will be uploaded to Grayson’s YouTube channel at bit.ly/graysonchannel. All presentations from the virtual Welfare and Safety of the Racehorse Summit can be found on this page.

The virtual Welfare and Safety of the Racehorse Summit kicked off May 12 with a presentation by Dr. Katherine Garrett of Rood & Riddle Equine Hospital, who discussed the uses and advantages of different imaging modalities. She also highlighted common injuries to the fetlock.

On May 19, Dr. Dionne Benson, chief veterinary officer of The Stronach Group, moderated a panel consisting of Dr. Ryan Carpenter, a private veterinarian in California; Dr. William Farmer, the equine medical director for Churchill Downs Incorporated; and Dr. Scott Palmer, the equine medical director for the New York State Gaming Commission. The group emphasized the importance of transparency in medical records throughout a horse’s racing career.

The May 26 webinar featured Dr. Mick Peterson, executive director of the Racing Surfaces Testing Laboratory and professor of Biosystems and Agricultural Engineering at the University of Kentucky. Dr. Peterson focused on the Maintenance Quality System, which monitors track conditions. His presentation also included interviews with Glen Kozak, the New York Racing Association’s (NYRA) senior vice president of Operations & Capital Projects; Jim Pendergest, general manager of The Thoroughbred Center and director of Surfaces at Keeneland; Dr. Stephanie Bonin, biomedical engineer at MEA Forensic; and Dennis Moore, track superintendent at Del Mar and Santa Anita.

The fourth webinar was moderated by Dr. Jennifer Durenberger, The Jockey Club steward for NYRA, on June 2. This session featured a presentation by Dr. Sue Stover, professor of Surgical and Radiological Sciences at UC Davis School of Veterinary Medicine. She delved into findings from the California Horse Racing Board’s postmortem program. Stover noted that catastrophic injuries are the result of pre-existing conditions and tend to occur in predictable locations.

Among the major accomplishments that have evolved from the previous eight summits are the Equine Injury Database; the Jockey Injury Database; the Racing Surfaces Testing Laboratory; a uniform trainer test and study guide; the racing surfaces white paper and publication of educational bulletins for track maintenance; the publication of stallion durability statistics; the Hoof: Inside and Out DVD, available in English and Spanish; protocols for horses working off of the veterinarian’s list; recommended regulations that void the claim of horses suffering injuries during a race; and inclement weather protocols.

Grayson-Jockey Club Research Foundation is traditionally the nation’s leading source of private funding for equine medical research that benefits all breeds of horses. Since 1983, the foundation has provided more than $28.8 million to fund 383 projects at 45 universities in North America and overseas. Additional information about the foundation is available at grayson-jockeyclub.org.

Record Low in 2019 for Equine Fatalities in Racing

Despite problems at Santa Anita Park, racing in U.S. and Canada enjoys safest year.

 

Despite a rash of breakdowns at Santa Anita Park, the overall number of catastrophic injuries during racing fell 8.9% in 2019 compared with 2018.

The equine fatality rate of 1.53 per 1,000 starts is the safest year on record in the 11 years The Jockey Club Equine Injury Database has tracked such incidents in the United States and Canada. The EID tracks equine fatalities during racing, which allows wide participation and facilitates comparison from year to year.

Based on the 2019 data, 99.84% of flat racing starts at the racetracks participating in the EID were completed without a fatality. The overall drop in the risk of fatal injury from 2009-19 was 23.5%.

Turf Paradise Reports 40% Decline In Racing Fatalities After New Safety Protocols

Phoenix-based Turf Paradise, Arizona’s largest horse racing track, saw racing-related equine fatalities fall by nearly 40% during the season that ended May 3, according to a press release from the Rose, Moser, Allyn public relations firm.

During the 2017-’18 meet there were 7,452 starts and 23 Thoroughbred racing related equine fatalities. During the 2018-’19 meet there were 7,050 starts and 14 Thoroughbred fatalities. That’s 1.99 per 1,000 starts, which is dramatically down from 3.09 per 1,000 starts in 2017-’18. The national average is 1.68, according to the Equine Injury Database.

The sharp decline followed the implementation of a series of protocols including pre-race veterinarian inspection of all horses on every live race day. Those exams began in February and continued through the end of the season.

In the 2017-’18 race meet there were there were five fatalities in February, seven in March and two in April. For the 2018-’19 meet there was one fatality in February, zero in March and 1 in April.

Other measures taken include:

  • Trainer review of necropsy report following a fatality.
  • Track veterinarian review of horses while in the paddock, during warm-ups, gate loading and post-race exams.
  • Twice monthly testing of sand to dirt ratio balance on the main track.

 

A panel of experts also carefully reviewed safety protocols.  The Equine Wellness Committee composed of the Director of the Division of Racing, track and state veterinarians, the Arizona HBPA and the general managers of the state’s three race tracks met monthly to review data and make recommendations. Academic and private sector statisticians also reviewed horse injury statistics to spot any trends. That review is ongoing.

Turf Paradise general manager Vincent Francia said, “The protocols we initiated this season were a collaborative effort of Turf, the Arizona Division of Racing and the Arizona Horsemen’s Benevolent and Protective Association. We are encouraged by the results, to have reduced fatalities by almost 40%. However, the goal is zero fatalities. The Committee is reviewing additional protocols.”

Turf Paradise opened its doors in in 1956 and has been at 19th Ave. and Bell Road ever since making it Arizona’s first sports franchise.

Fourteen Takeaways From The 2018 Jockey Club Welfare And Safety Summit

by | 06.27.2018 | 6:50pm

The Grayson-Jockey Club Research Foundation hosted its eighth Welfare and Safety of the Racehorse Summit June 27 at Keeneland, with speakers touching off on disaster preparedness, jockey safety, equine injury, and Thoroughbred aftercare.

Here are a few things I didn’t know before attending this year’s event:

  • Detail matters in disaster planning. Obviously, the San Luis Rey Downs tragedy and a pair of major hurricanes reiterated to everyone in the horse industry that wherever you keep horses, you need disaster plans. One thing people may not think about is the impact beyond the first hours following a hurricane, tornado, fire, or flood. Dr. Roberta Dwyer, extension veterinarian at the University of Kentucky, recalled a serious ice storm in Central Kentucky several years ago which left her farm property without power or vehicular access for a week.Some things you may not have thought of when making plans:
    -If you have well water, a loss of power also means a loss of water for your horses.
    -Your help may not be able to access the farm to look after horses.
    -Fencing or barns may be destroyed or unusable, and the longer access to your property is blocked, the longer it will take to get them fixed
    -Mass power outages will also mean that gas stations and ATMs will be non-functional
    -If you have more horses than trailer space and are forced to evacuate, you need to know which ones are going first and where you’re taking them.
  • An answer to an age-old question: Should horses be inside or out during a weather event? Dwyer said it depends on your barn, its location, and the type of weather that’s headed your way. If your barn is in a low-lying area and there’s a potential for flooding, the horses should be let out so they can seek shelter. If your barn is at the top of a windy hill and a storm system is coming, the barn may not be in the safest place for the horse. In the event of a tornado warning, Dwyer thinks flying debris is a big consideration and keeping horses inside may be the best way to protect them.
  • When it comes to weather at the track, change is a bigger problem than extremity. Horses, much like people, will gradually adjust to the temperature and humidity they’re exposed to. A panel made up of track managers and veterinarians agreed they’re more worried by significant changes in a short amount of time than they are warm or cold temperatures. Dr. Lynn Hovda, chief commission veterinarian for the Minnesota Racing Commission, noted Canterbury Park saw a change from two feet of snow to a high of 106 degrees in six weeks this season, along with significant humidity. That had her worried.Jeff Johnston, regional manager for the Jockeys’ Guild said he is more worried by ice than snow. Track surfaces are usually fine during icy weather because they’re harrowed a lot, but pathways to and from the paddock may not be. Further, Johnston pointed out changes from thaw and freeze can impact dirt surfaces in ways fans don’t think about. Before Turfway put in a synthetic surface, Johnston recalled overnight refreezing would tighten the dirt, but in the midafternoon on a weekend card, the ground would have thawed but not dried and the surface became loose and unsafe. This sometimes prompted race cancellations which the general public found difficult to understand.
  • The Equine Injury Database is starting to look at non-fatal injuries, and the results are pretty interesting so far. We knew that a horse’s appearance on a veterinarian’s list was an increased risk for fatal injury, but of course it also elevates the risk a horse will have a non-fatal injury. This does not seem to multiply with the number of separate instances a horse may have been placed on the list, but it also doesn’t ever go back down to normal again after the horse has been flagged once. Horses who have been on the list once have a 115 percent higher risk for fatal breakdown and a 79 percent higher risk for non-fatal fracture than horses who haven’t been flagged.Track-by-track data has also shown there’s variability in risk patterns post-veterinarian’s list depending on location – and obviously, regulatory body. When a horse comes off the list and is allowed to run, some locations saw the horse’s risk spike higher/spike longer than others.
  • …However, we need much, much more complete reporting before the database can provide us helpful guidelines to reduce risk. Parkin estimates he’s only getting about 25 percent of all non-fatal injuries that happen, between injuries that happen during training or incomplete reporting of injuries during the race day. There’s also a lot of injury risk we still don’t have a statistical explanation for, and more complete data could help fill in some gaps.
  • The private nature of veterinary records could be part of the issue – for Parkin, and for horses. Of course, it would be easier for Parkin to identify trends in horses’ history if he knew what they were being treated with and when. But veterinary records legally belong to the owner of the horse at the time a record was created, and aren’t required to be disclosed to subsequent owners, Parkin, or state officials (with a few limited exceptions). Parkin suspects it’s no accident then, that a horse’s risk of fatal injury is 28 percent higher in its first start with a new trainer than it was the last time it started. Part of that could be the trainer’s lack of familiarity with the horse, but part of it may be that he’s in the dark about what the horse has experienced medically.
  • In case you needed more evidence, bringing a horse back after an injury may not be worth it if the horse is running at the lower levels. That’s because, according to Parkin’s data, they’re probably going to be starting for a purse that’s 20 percent lower than what they were running for before injury. If you’re already running a cheap horse, you have to ask whether it’s worthwhile. Among horses who suffered a non-fatal injury, only 46 percent raced again; those who did had a fatal breakdown rate of 3.1 percent – significantly higher than the .18 percent through the rest of the population.
  • Microchipping can help with more than verifying identity at saddling time. Marc Guilfoil, executive director of the Kentucky Horse Racing Commission, noted that microchips can put a halt to abuse of shockwave therapy – if used correctly. The temporary analgesia produced by shockwave makes it a temptation for trainers to haul horses off-site to apply the therapy close to race time, then come back in. Prevailing wisdom suggests they may lie to the security attendant at the stable gate about the identity of the horse in the trailer (if they are asked for an identity at all) to evade suspicion. Guilfoil expects stable gate attendants can scan microchips to create a digital record of when a horse came on and off the grounds.
  • “Putting an inexperienced jockey on an inexperienced horse is a recipe for disaster.” Peta Hitchens, research fellow in the equine orthopedic research group at the University of Melbourne, presented stats gathered from five years of data from the California Jockey Accident Database. She found an apprentice has a 50 percent higher risk for injury than a fully-licensed rider, and several additional factors could add more risk on top of that 50 percent increase, including: the rider also has less than 250 races to their name; the horse has had less than five starts; the race is a sprint; the race takes place on a dry, fast track. Unsurprisingly, fatal injuries to horses are risky for riders: 60 percent of fatal horse breakdowns were accompanied by a jockey injury.
  • We’ve known rider falls are expensive, but now we know how expensive. Jockey claims in the Finish Line Insurance Group, which protects California riders, averaged a staggering $103,000 each in cases of fatal horse breakdowns. Claims for the average exercise rider fall: $28,000 each.
  • Besides being an important welfare consideration, having a sports medicine physician to look after the jockey colony can reduce costs. Dr. Kelly Ryan, primary care sports medicine physician with MedStar Health, admits her services don’t come cheap. MedStar contracts with the Maryland Jockey Club to allow Ryan to provide sports medicine and general care to jockeys and backstretch workers in the state. She does baseline concussion testing for jockeys and clears them to ride after an injury, but she also treats horse bites and kicks, coordinates follow-up care after accidents, and helps provide sports psychology services when needed.Ryan hears often from people who admire Maryland’s system of providing experienced care to their riders, but who say those services are inaccessible in other areas. Not true, she says. There are sports medicine physicians available nearly everywhere, and if you can’t find one of those, an athletic trainer can serve as a consultant on- or off-site for riders. Athletic trainers in other sports are on the court or field to be the eyes and ears of sports medicine doctors to identify potential problems an athlete may be battling. They’re also a lot cheaper than sports medicine physicians. Another cost consideration: In her role, Ryan says she reduces workers’ compensation claims because she can treat a lot of on-the-job injuries in her office at the track.
  • We’ve heard it before, but the quality of emergency care for a jockey is greatly improved when you have someone skilled on– Ryan is not the person riding in the ambulance to a fallen jockey during a race, but she can act as a conduit.“When you go to the hospital and they have on the paperwork ‘Complaint: rider fell from horse,’ that’s a lot different from the way we saw them, coming off at 40 miles per hour,” said Ryan, who can describe whether and where the rider was stepped on, and how exactly they hit the ground.
  • Language is key when it comes to talking about OTTBs. Jen Roytz, executive director of the Retired Racehorse Project and writer of our Aftercare Spotlight series, revealed one of the biggest misconceptions she encounters when talking to people about off-track Thoroughbreds. “Often they will tell me, ‘Oh I rescued him from the track,’” she said. “I constantly have to, very politely, correct them and say, ‘Why do you feel that horse was rescued?’ When they start talking through it, they convince themselves it wasn’t really ‘rescued.’ The lay person, mainstream public, does not give enough credence to how well cared for these horses are.”
  • Turf racing may be gaining stretch in the American landscape, and that comes with surface concerns. Trainer Graham Motion mentioned that he loves a good turf horse, but anecdotally he has concerns about long-term wear and tear on a track. This theme came up again from surfaces expert Dr. Mick Peterson, who noted there’s no easy way to freshen a turf surface. A few options for tracks trying to figure this out – change the racing schedule to let grass grow at the appropriate season, create short turf-only meets to give courses elsewhere on a circuit a rest, and increase the width of turf tracks.

Equine Injury Database: Rate of Fatal Injuries Declines for Fourth Consecutive Year

An analysis of data from the Equine Injury Database (EID) has shown a reduction in the rate of fatal injury for a fourth consecutive year and a 23 percent drop since 2009, The Jockey Club announced today.

When comparing 2016 statistics to 2015 statistics across all surfaces, ages, and distances, the rate dropped from 1.62 per 1,000 starts in 2015 to 1.54 per 1,000 starts in 2016. The overall rate of 1.54 per 1,000 starts is the lowest since the Equine Injury Database started publishing annual statistics in 2009.

Dr. Tim Parkin, a veterinarian and epidemiologist from the University of Glasgow, who serves as a consultant on the Equine Injury Database, once again performed the analysis.

“One of the primary objectives of this project from the outset was to build a comprehensive data source we could utilize to improve safety and prevent injuries, and we are now clearly achieving that goal,” said Dr. Parkin. “The racetracks, the horsemen, and the regulators who have implemented safety initiatives over this time period deserve a great deal of credit for this encouraging trend.”

On dirt, there has been a 19 percent drop since 2009.

On turf, there has been a 44 percent drop since 2009.

The rate on synthetic surfaces, according to Parkin, has remained stable since 2010, hovering in the 1.0 to 1.2 per 1,000 starts range.

A graph depicting all updated statistical data pertaining to surface, distance, and age is available at jockeyclub.com/pdfs/eid_8_year_tables.pdf.

“The sport, as a collective entity, has made a sustained difference that should serve as motivation to continue the search for new safety and welfare initiatives and to permanently eliminate the usage of ‘part of the game’ from the lexicon when discussing equine injuries,” said Dr. Mary Scollay, the equine medical director for the Commonwealth of Kentucky and a consultant to the EID.

The EID statistics are based on injuries that resulted in fatalities within 72 hours from the date of the race. The statistics are for Thoroughbreds only and exclude races over jumps from the calculations. Summary statistics for the EID are subject to change due to a number of considerations, including reporting timeliness.

Since March 2012, racetracks have been able to voluntarily publish their statistics from the EID in the Safety Initiatives section of The Jockey Club website. There are 25 tracks that self-reported during 2016 and their aggregate rate was 1.41.

The list of racetracks participating in the Equine Injury Database and detailed statistics from those tracks that voluntarily publish their results can be found at: jockeyclub.com/default.asp?section=Advocacy&area=11.

Throughout the course of 2017, racetracks accounting for approximately 96 percent of flat racing days are expected to contribute data to the EID.

The Equine Injury Database, conceived at the Grayson-Jockey Club Research Foundation’s first Welfare and Safety of the Racehorse Summit, was launched by The Jockey Club in July 2008 and seeks to identify the frequencies, types, and outcomes of racing injuries using a standardized format that generates valid statistics, identifies markers for horses at increased risk of injury, and serves as a data source for research directed at improving safety and preventing injuries.

The Jockey Club, founded in 1894 and dedicated to the improvement of Thoroughbred breeding and racing, is the breed registry for North American Thoroughbreds. In fulfillment of its mission, The Jockey Club, directly or through subsidiaries, provides support and leadership on a wide range of important industry initiatives, and it serves the information and technology needs of owners, breeders, media, fans and farms. It is the sole funding source for America’s Best Racing, the broad-based fan development initiative for Thoroughbred racing. You can follow America’s Best Racing at americasbestracing.net.
