The operating room environment can be a source of anxiety for the patient, including in the context of outpatient surgery for which anxiolytic medication is rarely used. This anxiety-induced effect can be reinforced by the patient's lack of active participation.

Some studies have already shown the feasibility of patient walking to the operating room (OR) and advantages this approach(Kojima and Ina 2002; Lack 2016; Nagraj et al. 2006).

Moreover, recovery room complications and pain have also been shown to be greater after varicose vein surgery in patients with significant preoperative anxiety (Scavee et al. 2016).

Therefore, the investigators decided to test the effects of walking to OR for patients admitted for outpatient surgery for varicose vein surgery.
