  1. aNegative value implies that outpatient anesthesia consultation clinic is less expensive than conventional approach; positive value implies that outpatient anesthesia consultation clinic is more expensive than conventional approach. b95 patients in the clinic group were admitted at least one day before surgery into hospital.
