INTRODUCTION Informed consent is an active process of the doctor-patient relationship, based on ethical and legal principles. The anesthetic act has inherent risks, which should be subject of specific consent. The aim of this study was to evaluate the degree of implementation of written specific informed consent for anesthesia in the context of elective surgery. MATERIAL AND METHODS An observational prospective study, at a tertiary university hospital, in 230 patients aged 60 years or older, undergoing elective surgery between May and July 2017. Eligible patients who consented to participate were interviewed clinically on the day before surgery. In the postoperative period, the anesthetic technique and the existence of the written informed consent for the anesthetic and surgical procedures were assessed. Patients who were unable to give informed consent or those admitted in the Intensive Care Unit after surgery were excluded. RESULTS Written informed consent for the surgical procedure was obtained for 225 (97.8%), while it was obtained in just 96 (41.7%) patients for the anesthetic act. There was a higher prevalence of stroke, anemia, and higher Charlson and physical American Society of Anesthesiologists scores in patients without written informed consent for the anesthetic act. DISCUSSION We identified a low implementation of written informed consent for anesthesia. This situation may have important implications in the context of disciplinary, civil or criminal liability. CONCLUSION Despite its importance, the practice of written informed consent for anesthesia in this institution is not yet implemented on a regular basis.
