Factors associated with prolonged treatment days, increased veterinary visits and complications in horses with subsolar abscesses

Abstract There is a lack of epidemiological studies about equine subsolar (hoof) abscesses even though they are among one of the most common causes of acute, severe lameness. The goals of this study were to (1) describe the equine subsolar abscess patient population of the University of Pennsylvania’s New Bolton Center’s Field Service and (2) to determine the factors that are associated with increased veterinary visits, prolonged treatment and complications. Descriptive statistics were performed on data collected from 160 cases of equine subsolar abscess. Inferential statistics were performed on a subset of those cases. No significant results were identified in relation to an increased number of veterinary visits. Poisson regression of days of treatment revealed that abscesses diagnosed in the summer (incidence rate ratio (IRR)=9.42, P
