Abstract
Objective—
To evaluate the influence on compliance of demographic variables and of the way of proposing a faecal occult blood test in a colorectal cancer mass screening programme.
Setting—
Well defined population in Burgundy (France).
Methods—
From 1988 to 1996 five screening rounds were conducted in people aged 4S to 74 on entering the study. The screening test was provided free of charge by primary care physicians over a four month period, then mailed to non-consultants, followed by a potential reminder letter. The whole population was invited to participate in each screening campaign.
Results—
During the five successive rounds, compliance was 52.8%, 54.0%, 57.3%, 58.3%, and 56.2%. It was higher in women than in men, in those initially aged 50 to 69 than in the extreme age groups, and in urban than in rural areas. Overall, 68.7% of the invited population completed at least one screening test and 37.2% completed the five rounds. Among those who participated once in a screening campaign, between 79.6% and 87.6% participated in the succeeding ones. Compliance was higher when the test was proposed by GPs (varying between 85.2% and 94.0% according to the screening campaign) than when it was sent by post (varying between 26.0% and 33.7%).
Conclusion—
In France, a participation rate of over 50% can be achieved in colorectal cancer screening by means of a faecal occult blood test. To achieve this, primary care physicians have to play an active part in the programme and the test must be mailed to non-consultants.
