Preoperative anxiety after face-to-face patient assessment versus preanaesthesia telemedicine (PANTEM) in adults: a randomised clinical trial.

Preanaesthesia consultation is performed to assess and optimise patient-specific risk factors before surgery, to inform patients about anaesthesia techniques and to obtain consent. Aside from face-to-face visits, telephone consultation is increasingly being used clinically. Concentration on the content and avoidance of confounding factors could lead to improved patient preparation.
