Abstract

Aims: To determine the prevalence of cervical vertebralmyelopathy (CVM) in a population of Thoroughbred horses.Methods: A retrospective descriptive analysis of free text recordsof horses over a 7 year period maintained by a Thoroughbredbreeding establishment. Content analysis software (ProvalisResearch, Canada) was used to determine CVM prevalence anddisease type (type I, type II, unknown), animal sex, age at diagnosisand outcome data. Chi-squared (Fisher's exact test whereappropriate) and Mann-Whitney Tests were performed. Results:Twenty-three cases of CVM were identified in the databaseresulting in an overall prevalence of 1.4% in this population ofhorses. There were significantly more male (n = 17) than femalehorses (n = 6) in the CVM group (P = 0.003). The age at diagnosiswas significantly greater for type II (1188.6 ± 95 days; range1085'1299) than for type I CVM (433.8 ± 220 days; range48'702) (P = 0.002). The 23 horses with CVM had one of 4outcomes: died (n = 17), went on to training (n = 2), lost to followup(n = 3) or retired to pasture (n = 1). Conclusions and PracticalSignificance: The prevalence data for this population suggeststhat CVM is an important disease of Thoroughbred horses andleads to wastage to the Thoroughbred industry through inabilityto race and loss of affected horses. Further investigations of theprevalence of CVM in other equine populations, determination ofrisk factors for development of the disease and intervention studiesare warranted in an effort to reduce the prevalence of thisimportant neurological disease. Content analysis software utilisingdefined search terms is useful for searching large databasescomprised of free text records and could be applied to routinelycollected clinical data in veterinary practice.
