PurposeTo evaluate the information that patients undergoing spine surgery truly receive and assimilate when they sign their informed consent documents.MethodsThis was a retrospective study on patients who underwent spine arthrodesis or spine discectomy. Patients were given a full explanation of the surgical technique to be employed and its potential risks before they were included on the surgical waiting list. Before surgery, they were asked to sign an informed consent form. The studied variables included whether patients read the informed consent form, whether they recalled the surgical technique used or the spinal segment operated, whether they were aware of the surgical risks involved, and if they had looked for information about their procedure elsewhere. Answers were analyzed by age and educational level.ResultsOf a total of 458 total patients, only 51.9% answered all the questions. Sixty-three percent of patients said they had read the informed consent document before surgery. Although 91.6% of patients were aware of the spine segment operated, only 73.5% remembered the surgical technique employed. A total of 63.9% of patients could recall the vertebral levels operated. 39.1% were not aware of the surgical risks involved, and only 16.0% of patients admitted having looked for additional information. A statistically significant correlation was found between the search for additional information and young age (p < 0.001) on the one hand, and high educational level on the other (p = 0.023).ConclusionEven though obtaining informed consent is an important procedure before spinal surgery, almost 40% of the patients in this study underwent surgery without reading the informed consent document or being aware of the risks posed by the procedure.© 2023.
