Better acceptance of Fecal Occult Blood Test (FOBT) for colorectal cancer screening during hospitalization.

INTRODUCTION: Colorectal cancer (CRC) is a leading cause of illness and death in the Western world. Screening with fecal occult blood test (FOBT) significantly reduces the death rate and the incidence from CRC but these tests are not widely accepted. We investigated the possible contribution of hospitalization to a better acceptance of CRC screening.

PATIENTS AND METHODS: From October 1998 through September 2000, 721 consecutive patients between 45 and 75 years of age admitted for various reasons were asked for participation in the study. They were asked to participate in FOBT-screening. In case of refusal of FOBT they were asked a second time after detailed information. In patients who accepted 3 consecutive FOBT's were performed. In case of positive FOBT results colonoscopy and gastroscopy were performed.

RESULTS: 149 (82 male/67 female) patients were included. 94 (63.5%) of them agreed to undergo FOBT primarily and 10 (6.8%) secondarily after detailed information. The total acceptance rate of the FOBT was 69.8% (m/w : 69.1%/71.6%). In one of 5 cases with a positive FOBT result colorectal cancer (CRC) was diagnosed. Information on repetition of FOBT after one year could be obtained from 82 patients (55%). 37 patients (45%) had undergone repeated FOBT. None of the 37 patients was motivated by the FOBT screening during hospitalization.

CONCLUSIONS: Staying in a hospital offers a good chance to achieve a higher acceptance of the FOBT. Therefore, hospitalization may contribute to a better colorectal cancer prevention. However, motivation to regularly repeat screening does not last in all patients. Therefore, public campaigns as well as medical counseling need to continuously stress the necessity of CRC screening procedures.
