BackgroundPast research has explored patients' expectations about the informed consent process. However, it is currently unknown if the complexity of the surgical procedure influences the type of anesthesia-related risks that patients wish disclosed. This study explored fears of anesthesia-related complications and whether these changed based on severity of surgery classification.MethodsPatients presenting to our pre-operative evaluation clinic from February 2013 to May 2013 were asked to participate in a survey-based study meant to evaluate their perception of five possible anesthetic risks (peripheral nerve injury, death, nausea and vomiting, heart attack and stroke) when confronted with differing levels of surgical severity.ResultsOne thousand surveys were administered, and 894 were returned for an overall response rate of 89%. Fear of death was the greatest concern as compared to the other risk factors independent of the severity of surgery. The level of fear for all risk factors, with the exception of stroke and heart attack, were dependent on the severity of surgery. Fear of death decreased as the severity of surgery decreased (major 46%, moderate 38%, minor 25%). For major surgery, the fear of perioperative death differed significantly with age (P < 0.001); specifically, with increasing age came a lessened fear of death.ConclusionAwareness by anesthesia providers of those fears that patients report may allow for a more personalized approach to providing information that may better allay anxiety. Further, these results may better tailor the informed consent process to one that meets particular patient concerns.© 2014 The Acta Anaesthesiologica Scandinavica Foundation.
