In a long-term care facility, the fecal guaiac test for occult blood was used as a screening method to detect gastrointestinal (GI) bleeding lesions. The study involved 450 chronically ill hospitalized patients whose average age was 70 years. Each underwent 6 fecal guaiac tests for three consecutive days while receiving a standardized meat-free, high-fiber diet. ⋯ In 20 of the 21 patients with positive test findings, a lesion of the GI tract was found. The therapeutic implications of such screening are important. This study emphasizes the value of routine fecal hemoccult testing of whole institutional populations once or twice a year.
