Impact of Attentional Tunelling on a Population of French Practitioners
An observational study of Awareness and Attention, run by Centre Hospitalier Universitaire de Nice at 1 site in France.
Trial summary
The tunnel effect, also known as attentional tunnelling, is a cognitive bias affecting all healthcare professionals, including odontologists. It is characterised by an excessive focus on a specific element of a clinical situation, which can alter the overall assessment and lead to errors in medical practice. Read more about this study

About this study
Official title: Impact of Attentional Tunneling or the "Tunnel Effect" in Dentistry. Multi-centre Cross-sectional Study of a Population of French Practitioners.
The tunnel effect, also known as attentional tunnelling, is a cognitive bias affecting all healthcare professionals, including odontologists. It is characterised by an excessive focus on a specific element of a clinical situation, which can alter the overall assessment and lead to errors in medical practice. This poses a particular risk to the quality of dental care, especially surgical care. Despite the importance of this risk, few studies have addressed this issue in dentistry. Therefore, raising the dental community's awareness of this phenomenon on a large scale is both justified and necessary.
- Being tested
- Face-to-face or online survey
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Face-to-face or online surveyOther
A face -to-face or online questionnaire will be given to study paticipants after a seminar on attentional tunneling organized by Professors Dridi and Charavet.
