[Evidence-based planning: the case of mass screening for colorectal cancer in the Lazio region of Italy].
Several population-based trials have shown the efficacy of colorectal cancer mass-screening based on guaiac faecal blood testing in a generic risk population. SCCR represents a very complex and resource-demanding public health intervention and, for this reason, its planning requires actual efficacy as a main goal. Since evidence of efficacy demonstrated by population-based trials may not actually generate effectiveness, the Regional Government of Latium Region decided to implement some experimental studies before introducing a screening programme, in order to define an evidence-based organisational model of SCCR and a feasibility evaluation of the real needs for screening. The aims of the pilot studies were to define an evidence-based organisational model, to evaluate the necessary resources and the actual quality standard of clinical examination, treatment and surgery. The aim of the feasibility study is to test the organisational model for SCCR for about 300,000 citizens residing in the Latium region. The present article illustrates the scheduling path set out, which is based on the involvement of experts, GP representatives and specialists from scientific societies and it is planned by the following actions: Definition of evidence-based recommendations; identification of further investigations; realization of experimental studies; definition of an evidence-based organisational model. The main research areas have been dealt with using randomised trials, in order to evaluate the efficacy of the involvement of GPs and the kind of test for RSOF Our work has produced evidences which were sometimes in contrast with information in the literature, demonstrating that guaiac RSOF testing is less reproducible and determines lower uptake than immunochemical testing. Our work also shows that the involvement of GPs should be based on their personal skills rather than on their role. Such evidences are fundamental to the definition of the organisational model and confirm the need of basing an evidence-based planning not only on evidences found in the literature. The necessity of this approach is strengthened by the level of organisational complexity and by the amount of resources needed to put a public health intervention into practice.
