Abstract
Objectives
To produce an informed consent for CT colonography (CTC), to be diffused by the Italian Society of Radiology, aimed to make patients and referring physicians aware of CTC examination protocol, advantages and disadvantages, limits and potential related risks.
Materials and methods
Delphi method was used to create a consensus among experts on an informed consent for CTC. The overall agreement among different consulted specialists was evaluated and ranked using the Cronbach’s correlation coefficient (α) at two time points: after the first and the second ‘round’ of consultation.
Results
The Cronbach index was 0.84 at the end of the first round and 0.93 at the end of the second round. The number of disagreements dropped from an overall of 11–5, from the first to the second round.
Conclusions
The experts were able to produce an informed consent for CTC, hoping that this may be the beginning of a process focused on implementation of quality standards in CTC.
