To the extent that economic evaluation of medical technology is frequently antedated by its diffusion, the prospects for "nay saying" in the light of opportunity costs are limited. This study provides a prospective analysis of the cost of confirmatory testing for a program not yet introduced - use of the faecal occult blood test (FOBT) for colorectal cancer screening. Specifically, it evaluates alternative diagnostic workup strategies - based on existing data on the prevalence of cancers, adenomas and other conditions; the sensitivity and specificity of confirmatory tests (rigid sigmoidoscopy, flexible sigmoidoscopy, double-contrast barium enema and colonoscopy); risks; and net costs to Medicare. Two dominant protocols are identified among the 22 protocols examined. The average cost of one with the best diagnostic yield is conservatively estimated to be $174 per FOBT positive individual. Clearly, a cheap screening test does not equate with an inexpensive screening program.
