[Quality sharing between the national health service and citizens: a diagnostic and therapeutic planning experience at the "S. Maria" Hospital in Terni].

The Diagnostic and Therapeutic Programs are instruments of clinical management. The authors report on their experience with the construction of a Diagnostic and Therapeutic Program in the field of breast cancer. This is the result of collaboration between the Breast Unit, an administrative team and a computer team at the "S. Maria" Hospital in Terni. The implementation of the guidelines in the hospital setting makes it possible to systematise the clinical activities, to quantify the economic impact for each disease, and to plan any changes in the use of resources. The application of this method, moreover, makes it possible to develop a common language between medical and nursing staff which can be easily understood by the patients and to inform patients adequately with regard to the diagnostic and therapeutic program they will have to comply with for their respective conditions.
