Is it safe to use telephone for anaesthesia consultation in high-risk patients before non-invasive surgery? A pilot study in ophthalmology.

BACKGROUND:Although telemedicine with video support for preoperative evaluation has been found effective, there is limited research on anaesthesia consultation by phone without video support, particularly among high-risk patients. To evaluate the effectiveness, safety and potential benefits of performing pre-anaesthesia evaluation by phone before eye surgery in patients having non-invasive surgery, we performed an observational study in a French teaching hospital. METHOD:All elective patients having elective ophthalmic surgery were included to have a consultation by phone instead of an in-person consultation, regardless of the type of anaesthesia or ASA score. The incidence of day-of-surgery cancellations, patient satisfaction and time/distance saved through phone consultations were assessed. RESULTS:From February to October 2022, data of 3480 patients were analyzed, including 370 (11%) high-risk patients (ASA 3-4). Anaesthesia-related day-of-surgery cancellation rate was 0.5% (n = 20) due to non-compliance with pre-operative instructions. No cancellation was due to inadequate pre-operative evaluation. No difference in cancellation rate was observed between low-risk patients and high-risk patients. Telephone consultations saved patients a mean of 126 min and 86 km. A younger age, an active status and living far from the hospital were associated with phone consultation preference. CONCLUSION:Phone anaesthesia consultation seems to be effective and safe before ophthalmic surgery, regardless of patient's perioperative risk. In addition, phone consultation provides significant time and distance savings. Our results must be confirmed through a multicentric randomised study comparing phone and traditional consultation in ophthalmology as well as in other non-invasive surgical procedures in a high-risk patients population.
