Screening and optimizing patients for OSA in the perioperative period may reduce postoperative complications. Despite controversy, there is a lack of studies with regard to the importance of shared decision-making and patient preferences in this context. It is unknown whether patients with suspected OSA, when given information about OSA, would be willing to delay surgery to diagnose and manage their condition preoperatively. This study consisted of a self-administered questionnaire that surveyed patients, patient relatives, or any accompanying members. The objective of this study was to determine whether respondents preferred to 1) proceed with surgery as planned, 2) delay surgery to ensure the medical condition of OSA is diagnosed and optimized, or 3) let his/her physician decide. Increasing emphasis and significant value has been placed on shared-decision making between patients and physicians. Educating patients about the risks of OSA and incorporating patient preferences into the perioperative management of OSA may be warranted.
