The cause of death in inflammatory bowel disease: a comparison of death certificates and hospital charts in Rochester, New York.

Abstract

Sixty-eight percent of Crohn's disease and 78% of ulcerative colitis patients died from causes unrelated to their inflammatory bowel disease. Deaths caused by Crohn's disease decreased from 44% in the 1973-1980 period to 6% in the 1981-1989 period. Crohn's disease was a direct cause of death in 25% of the female patients, whereas only 6% of male patients died directly of Crohn's disease. Colorectal cancer caused 14% of the deaths in ulcerative colitis patients, three times more often than in Crohn's disease patients. Excluding cancer, there were only two deaths directly due to ulcerative colitis, both in the first 2 yr after diagnosis.
