The Risk of Surgical Cancellation in Adult Patients Assessed by Telephone Versus In-person for Scheduled Non-cardiac Elective Surgery.

The COVID-19 pandemic accelerated the adoption of telemedicine, including its application in preoperative anesthesia evaluations. While the use of telephone assessments in anesthesiology is increasing, there is ongoing debate about their accuracy in identifying medical risks and predicting potential post-surgical outcomes. Preanesthetic evaluations are essential for determining patient suitability for surgery and for classifying surgical risk.

Despite the benefits of increased accessibility and cost reduction associated with telephone assessments, concerns persist regarding their ability to match the thoroughness of in-person evaluations. This is particularly relevant given the potential for higher rates of surgical cancellations.

In Colombia, telephone preanesthetic evaluations for non-cardiac elective surgeries are a recent development that may optimize resource use and enhance patient satisfaction. However, it is crucial to investigate whether they lead to a cancellation rate comparable to that of in-person assessments, as this could be a significant barrier to widespread implementation. This study examines the effectiveness of telephone assessments for non-cardiac surgeries and their impact on surgical cancellations compared to in-person preanesthetic evaluations. A secondary objective of the study is to evaluate the incidence of perioperative complications, including cardiovascular issues, pulmonary complications, bleeding, unexpected ICU admissions, and non-anticipated difficult airways.
