Demographics and costs of colic in Swedish horses.

The research article is about a study that was carried out to understand the incidence, demographics, costs, and risk factors associated with colic in Swedish horses through an analysis of insurance data. Colic, as a significant cause of morbidity and mortality, was defined by the need for costly veterinary care or life claims paid out due to the condition.

Research Methods

• The researchers used the data from one insurance company from 1997 to 2002. They included all horses aged less than 21 years and who had complete insurance for veterinary care and life during that period.
• The study defined colic as conditions where the main symptom was abdominal pain and related to the horse’s gastrointestinal system.
• The analysis included measurements such as incidence rates by variables including sex, breed group, age category, and geographical location (urban versus otherwise).
• In addition to these metrics, the researchers also considered factors like survival after colic diagnosis, medical costs due to colic, and multivariable modeling of risk factors related to the occurrence of colic.

Research Findings

• The study identified 3,100 horses with a colic diagnosis out of 116,288 horses that contributed to 341,564 horse years at risk (HYAR). Of these diagnosed horses, 27% were settled for life insurance.
• The median cost of veterinary care for a colic condition was found to be 4,729 Swedish Kronor (SEK).
• The overall incidence and mortality rates of colic were calculated to be 91 and 24 events per 10,000 HYAR, respectively. One-month survival post colic condition was determined at 76% with a 95% confidence interval standing at 75-78%.
• The researchers also noted that the incidence of colic varied based on breed group, horse’s age, and seasonality.
• Finally, they concluded that the mortality incidences probably reflected the true mortality rates due to colic and that the relatively high costs of veterinary care likely underestimated the risk of colic, as they represented only the more costly events.
