Télémédecine, téléconsultation en médécine périopératoire./ [Telehealth in peroperative medicine].

Telemedicine is booming in every medical sector. Besides being one of the WHO's priorities to deal with health cost and accessibility issues in both industrial and developing countries, recent COVID-19 sanitary crisis showed that it could be precious to ensure continuity of care in conditions of crisis. Telehealth is developing in anaesthesia in the whole perioperative period. This review focuses on recent data from literature on anaesthetic preoperative assessment. Four main issues are discussed: (1) eligibility and feasibility of telemedicine for anaesthetic preoperative assessment; (2) its effectiveness regarding time of consultation, surgery cancellation rate and concordance of physical examination; (3) patients' satisfaction and; (4) its potential economic impact.
