We selected 13 hospitals, out of 20 to participate in the screening programme, in order to represent all types of gastroenterology units (5 university hospitals, 2 large research hospitals, 6 local hospitals) and all geographic areas (7 in the metropolitan area of Rome, 2 in the outskirts of Rome, 4 in towns and small cities of the province). We included in a survey about screening attitudes all the GPs with an office in the 13 selected hospital districts. During the survey, all the GPs were asked to participate in a trial to evaluate the best strategies to enhance the compliance to CRCS. The conditions for eligibility of the GPs were: more than 100 people aged 50?74 in the practice population; a personal computer in the office; and consent to participate.
For each of the 13 districts we sampled 10 eligible GPs. The sampled GPs, primary sampling units, were randomised as follows: for each district, five to the immunochemical test and five to the Guaiac test. We sampled 2/10 of the target practice population for each GP; 1/10 of the population was randomised to the GP arm and 1/10 to the hospital arm.
We analysed the lists of randomised patients: the second member of a pair with the same telephone number was rejected and substituted, if assigned to a different arm.
