This work highlighted the beneficial role in terms of carers' satisfaction, quantity and quality of information transmitted.

Communication and information transmission problems are responsible for the majority of serious adverse events. The use of a checklist in the operating theatre has demonstrated its benefit in terms of reducing morbidity and mortality Regarding transmissions between caregivers, numerous studies have shown the great difference between the medical data of a patient in their file and the information transmitted.
