[A traditional anesthesia consultation or a "telephone interview" within the framework of ambulatory surgery?]

Abstract

Preoperative assessment for anaesthesia must detect in the setting of ambulatory surgery both medical and sociopsychologic problems which may contraindicate the ambulatory aspect of the procedure. The goal of our prospective study was to assess the efficacy of a preoperative telephone interview in screening the medical and sociopsychologic problems of ambulatory patients. 1,000 consenting consecutive outpatients participated to the study and were randomly allocated to one of two groups: patients in the standard group (STD) had a consultation a few days before surgery whereas those in the telephonic group (TEL) called the anesthetist a few days before, the physical exam being performed on the day of surgery. The cancellation of the ambulatory procedure was decided upon either medical criterias (MC) or sociopsychologic criterias (from Waetchler).

Results: both groups were comparable regarding SPC and MC but prescription of preoperative tests was more frequent in the STD group (result statistically significant). In conclusion, this new approach is as reliable as the standard consultation in screening the SPC which remain the most frequent cause of cancellation in ambulatory surgery. Therefore this telephonic interview which is simple and reliable for screening outpatients may represent a suitable alternative to a standard consultation.
