Objective---To estimate the national incidence of, operation-level risk factors for, and annual economic impact of colic among horses in the United States during 1998 and 1999. Design---Epidemiologic survey. Animals---21,820 horses on 1,026 horse operations in 28 states. Procedures---Horses were monitored for colic for 1 year, and results were recorded in a log that was collected quarterly. Operation-level data were collected via 4 on-site personal interviews. Associations between colic and independent variables adjusted for size of operation were determined. Results---Annual national incidence of colic in the US horse population was estimated to be 4.2 colic events/100 horses per year. Case fatality rate was 11%, and 1.4% of colic events resulted in surgery. Annual cost of colic in the Unites States was estimated to be $115,300,000. Conclusions and Clinical Relevance---The national impact of equine colic is substantial because of the high case fatality rate. (J Am Vet Med Assoc 2001; 219:67-71).
