Risk factors for horse falls in New Zealand Thoroughbred jumps racing

This study aimed to determine the incidence of, and risk factors for race-day horse falls in Thoroughbred jumps (hurdle and steeplechase) racing in New Zealand. Incidence rates for race-day horse falls in jumps races from 2005/6 - 2018/19 racing seasons (n = 13,648 race day starts) were calculated per 1000 starts. Univariable and multivariable analyses of race-, horse- and jockey-level risk factors for horse falls were conducted using Poisson regression in a generalised linear mixed model. The incidence rate of horse falls in jumps races was 42 (95 % confidence intervals [CI], 39 - 45) per 1000 starts. Horse falls in steeplechase races were 1.6 (95 % CI, 1.4 - 1.9) times more likely than hurdle races. The incidence rate ratio (IRR) for horses falling at the last three jumps in comparison with the first three jumps was 3.1 (95 % CI, 2.8 - 3.5) for hurdle and 4.4 (95 % CI, 3.9 - 5.0) for steeplechase races. Greater jockey (age, P = 0.02) and horse experience (P = 0.001) were associated with a lower IRR of falls (P = 0.05). Longer races (P = 0.02) and those held in autumn compared to winter (IRR 1.4; 95 % CI, 1.0 - 1.8; P = 0.05) were associated with a higher rate of falling in steeplechase races. A regulatory change enhancing discretionary ability of jockeys to pull up 'in-race' was associated with reduced horse falls (IRR 0.65; 95 % CI, 0.51 - 0.82; P = 0.001). Pragmatic rule changes within the industry can have a positive effect on reducing risk and improving equine welfare.

Risk factors associated with horse fall severity whilst racing over Grand National fences pre- and post-changes to their structure

This study investigated whether the modifications made to Grand National (GN) fences at Aintree, Liverpool, UK in 2012 following the Review of Safety and Welfare commissioned by the British Horseracing Authority (BHA), reduced the number and severity of ridden horse falls. The study also investigated whether the number of fences in a race and the total starters were positively linked to falls, and whether horse and jockey experience had any bearing. Videos of 36 races run between 2008 and 2016 recording all horse falls were retrospectively reviewed. Eighteen of the races were run prior to the 2012 changes made to the fences and 18 after the modifications. Falls were graded using a pre-determined severity scale, and previous experience of jumping GN fences. The severity scale was developed by the authors based on the literature and their perception of the degree of injury caused to the rider. The number of falls pre- and post-GN fence modification were adjusted to generalised linear models using the number of falls and severity of falls as dependent variables. A significant decrease in fallers was seen (P<0.001) after changes were made to the GN fences, together with a reduction in the probability of all levels of severity of fall. The severity scores decreased with increasing number of fences (P<0.001). When there were more starters in a race, a greater probability of horse falls was observed (P<0.001). No positive association between horse’s experience of jumping GN fences and horse falls, or jockey licence and horse falls was found (P>0.05). This study revealed that by implementing the changes recommended by the BHA, which included modifying the GN fences, the number and severity of ridden horse falls decreased. Horse and rider welfare was improved, contributing positively to the debate and public perception of the horseracing industry.

Internet Survey Evaluation of Demographic Risk Factors for Injury in Canine Agility Athletes

Objective

The purpose of this study was to compare previously identified demographic risk factors for injury in agility dogs, and explore other potential associations with demographic risk factors in new populations, and across different levels of injury severity.

Procedures

An internet-based survey of agility handlers was conducted. The primary outcome was if the dog had ever had an injury that kept from agility for over a week. Demographic information about the dog and handler were recorded. Logistic regression was used to quantify associations between variables of interest with injury history and all models were adjusted for age. Analyses were stratified by geographic location. Final model building was done via backward selection.

Results

The sample included 2,962 dogs from North America and 1,235 dogs from elsewhere. In the North American sample, 8 variables were associated with injury history; dog breed, height and weight, handler age, gender, agility experience, competing at the national level, age dog was acquired, and taking radiographs to assess growth plate closure. In the non-North American sample, 4 variables were associated with injury history; breed, handler age, occupation (dog trainer or not), and handler medical training. In both samples, Border Collies showed a marked increase in injury risk (ORs 1.89 and 2.34) and handler age >65 was associated with lower risk (ORs 0.62 and 0.77). Consistent with previous studies, greater handler experience was associated with reduced risk in the North American sample, but the other sample did not show this pattern, even in unadjusted models. Dog spay/neuter status was not associated with injury risk in either sample.

Conclusions and Clinical Relevance

Dogs with radiographs assessing growth plate closure may have increased injury risk as this population of owners may plan to train their dog harder, and at an earlier age. This finding also poses the question of whether or not growth plate closure is a good indicator of safety for increasing training intensity. Knowledge of what risk factors exist for injury in agility dogs is imperative in determining direction for future prospective studies, as well as creating recommendations to help prevent injury in this population of dogs.

The Impact of COVID-19 on Staff Working Practices in UK Horseracing

Simple Summary

Although coronavirus stopped horseracing in March 2020, most staff were classified as essential workers due to equine care and continued to work throughout lockdown. The physical and psychological impact of working during lockdown is unknown, and staff stress could have negative implications for racehorse welfare. Over half of staff surveyed were still working during lockdown. Racing grooms and stud staff were more likely to be working than most sectors, due to the timing of lockdown with the racing calendar and foaling season. Administrative staff were busier during lockdown, completing additional risk assessments or paperwork. Most staff reported that workplace changes were successful in protecting health and safety, but flat racing grooms felt that work-based changes were less effective. Negative perceptions of work-based COVID-19 changes may affect the staff’s ability to complete daily tasks and thus influence the quality of care provided to horses in their charge. Trainers and part-time staff were concerned about job security, highlighting a need for further employee support structures following the pandemic. The racing industry has prioritised staff health and safety but continued reflection on staff well-being, demands and working practices will maximise staff’s ability to care for horses under their charge, and allow racing to maintain the highest standards of equine welfare.

Abstract

Due to COVID-19, horseracing was required to cease all activity in March 2020; however, little is known about the pandemic’s impact on staff working practices. This study investigated the impact of COVID-19 on staff working practices during the initial lockdown phases. An online survey about working conditions during lockdown was answered by 287 participants. Chi-squared tests for independence and binary logistic regression (BLR) analysis was undertaken. A total of 53.7% (n = 154) of staff were working during lockdown. Pandemic-specific workplace changes were reported as effective by 87.8% (n = 115) of staff. Flat grooms reported workplace changes as less effective (χ² (52, n = 131) = 92.996, p < 0.001). A total of 67.2% (n = 193) of staff were positive about job security. Trainers and grooms were significantly less likely to report jobs as secure (χ² (52, n = 287) = 75.653, p < 0.05). The findings suggest that most of the racing industry positively received changes made by their employers to tackle the pandemic, and for staff still working during lockdown, their health and safety was prioritised. Continued development of employee support structures to promote job security and workforce stability is advised, which will minimise the disruption of staff changes on the care and welfare of the horses.

Faults in international showjumping are not random

Performance analysis (PA) involves the systematic observation and analysis of factors identified to enhance performance to improve athlete decision-making in a specific sport. PA is commonplace in human sports, yet despite potential advantages, its application remains limited in equestrianism. This study aimed to evaluate if factors anecdotally associated with performance in elite showjumping influenced competitive success. 250 combinations attempting 3,052 jumping-efforts across 2nd round European Fédération Equestre Internationale Nations Cup 2017 competition were analysed. Types of fault (e.g. pole down, refusal, etc.) were recorded as well as characteristics of the jump (e.g. jump type, approach angle). Combinations jumped clear at the majority of attempts (93.6; n=2,857) with faults only occurring at 6.4% of jumps (n=195). The most common faults were knock-downs (5.5%), time penalties (0.8%), faults at water jumps (0.3%) and refusal (0.2%). Faults were distributed across all fence types, however, were more common at upright fences (49%) and within combination fences (41%). A linear relationship was found between jumping-effort number and number of fences knocked-down (r=0.7; P<0.001). There were 2.8 times more knock-downs for the second half of the course (efforts 9-15) compared with jumping-efforts 1-7 (P<0.05). Faults were 4 times more likely at jumping-efforts 3, 4, 5 and 8 in the first half of the course (P<0.03) which increased to being 9 times more likely in the 2nd half of the courses (jumping-efforts 9, 10, 11, 12, 13 and 14; P<0.006). A straight approach to a jumping-effort reduced the chance of faults by 48% (P<0.0001) compared to a non-straight approach. These preliminary results suggest faults are not randomly distributed in elite showjumping and that patterns exist within fault accumulation demonstrating that the application of PA techniques in equestrian sport could lead to a performance advantage.

A retrospective case-control study to investigate horse and jockey level risk factors associated with horse falls in Irish Point-to-Point races

Horse racing as a high-risk sport can pose a significant risk to equine welfare. There have been limited epidemiological reviews of fall risk specific to point-to-point racing. This study aimed to identify horse and jockey level risk factors associated with horse falls and compare these to published findings for Hurdle and Steeplechase racing. The study used a retrospective matched case-control design. Relevant variables were identified, and information was collated for all races in the 2013/2014 and 2014/2015 seasons. Cases and controls were matched with a 1:3 ratio. Controls (n=2,547) were selected at random from all horses that completed in the same race (n=849). Horse and jockey level variables were analysed through univariable analysis to inform multivariable model building. A final matched case-control multivariable logistic regression model was refined, using fall/no fall as the dependent variable, through a backward stepwise process. Horse age was associated with an increased risk of horse falls. For every 1 unit increase in age there was a 1.2 times increased fall risk. The number of races ran within 12 months was associated with a decreased risk of falling. The jockeys previous seasons percentage wins was associated with the risk of horse falls. Jockeys who had 0-4% wins and 5-9% wins had an increase in risk compared to those who had over 20% wins/runs. The jockeys previous seasons percentage of falls (F) or unseating of the rider (UR) was associated with the risk of horse falls with jockeys who had over 20% F/UR having a 50% increased chance of falling compared to those who had 0-4% F/UR. Retrospective analysis of horse and jockey falls has exposed risk factors that have been previously identified in hurdle and steeplechase racing. Identification of risk factors is essential when considering future research and interventions aimed at improving horse and jockey safety.

A retrospective case control study to investigate race level risk factors associated with horse falls in Irish point-to-point races

Horseracing as a high-risk sport can pose a significant risk to equine welfare. To date no epidemiological reviews of fall risk in horseracing have investigated the risks specific to point-to-point (PTP) racing. This study aimed to identify the main race level risk factors associated with horse falls in Irish PTP and to compare these to published findings for hurdle and steeplechase racing. The study used a retrospective case-control design. Relevant variables were identified and information was collated for all PTP races in the 2013/14 and 2014/15 seasons. Race-level variables were analysed through univariable analysis to inform multivariable model building. A final multivariable logistic regression model was refined, using fall/no fall as the dependent variable, through a backward stepwise process with variables retained if likelihood ratio test P-values were <0.05. During the study period 1,358 PTP races were recorded, 727 races (54%) included at least one horse fall. The fall frequency noted during the current study was 88/1000 starts. Race category impacted the odds of a fall occurring with all categories of maiden races having increased odds of falls compared to open races. Maiden races for 6 year olds and 6 and 7 year olds had the greatest chance of falling with 6.9 times increased odds. The chance of a race containing a fall increased 38% for each additional runner and was reduced by 25% for every horse that pulled up during the race. Using a larger data set could enable further sub-models to be developed. In the current study some of the variables had a low number of cases and/or controls which limited the analysis. Retrospective analysis of fall risk exposed some risk factors that have been previously identified in hurdle and steeplechase racing. The variables identified could inform future research and interventions aimed at improving horse and jockey safety whilst racing.

Jump Horse Safety: Reconciling Public Debate and Australian Thoroughbred Jump Racing Data, 2012-2014

Simple Summary

This paper documents the dynamics of Australian thoroughbred jump racing in the 2012, 2013, and 2014 seasons with the aim of informing debate about risks to horses and the future of this activity. We conclude that the safety of Australian jump racing has improved in recent years but that steeplechases are considerably riskier for horses than hurdle races.

Abstract

Thoroughbred jump racing sits in the spotlight of contemporary welfare and ethical debates about horse racing. In Australia, jump racing comprises hurdle and steeplechase races and has ceased in all but two states, Victoria and South Australia. This paper documents the size, geography, composition, and dynamics of Australian jump racing for the 2012, 2013, and 2014 seasons with a focus on debate about risks to horses. We found that the majority of Australian jump racing is regional, based in Victoria, and involves a small group of experienced trainers and jockeys. Australian jump horses are on average 6.4 years of age. The jump career of the majority of horses involves participating in three or less hurdle races and over one season. Almost one quarter of Australian jump horses race only once. There were ten horse fatalities in races over the study period, with an overall fatality rate of 5.1 fatalities per 1000 horses starting in a jump race (0.51%). There was significant disparity between the fatality rate for hurdles, 0.75 fatalities per 1000 starts (0.075%) and steeplechases, 14 fatalities per 1000 starts (1.4%). Safety initiatives introduced by regulators in 2010 appear to have significantly decreased risks to horses in hurdles but have had little or no effect in steeplechases. Our discussion considers these data in light of public controversy, political debate, and industry regulation related to jump horse safety.
