Risk of after-hours visits to an in-hospital food animal service by species

Abstract

Computer records were accessed documenting in-hospital accessions to the food animal service maintained by the University of Missouri, College of Veterinary Medicine between January 1, 2001 and December 6, 2004. For each species category, the prevalence and relative risk (RR) of after-hours admission were calculated. The prevalence of after-hours visits varied from 0.040 for swine to 0.234 for South American camelidae. Using cattle as a reference level, the relative risk for an after-hours admission was decreased in swine (RR = 0.51) and increased in South American camelidae (RR = 3.04) and sheep or goats (RR = 1.66). The likelihood of an after-hours admission differed significantly among groups. Copyright © 2006 by the American College of Veterinary Internal Medicine.
