BackgroundInformed consent is an ethical and legal requirement that differs from informed decision-making-a collaborative process that fosters participation and provides information to help patients reach treatment decisions. The objective of this study was to measure informed consent and informed decision-making before major surgery.Study DesignWe audio-recorded 90 preoperative patient-surgeon conversations before major cardiothoracic, vascular, oncologic, and neurosurgical procedures at 3 centers in the US and Canada. Transcripts were scored for 11 elements of informed consent based on the American College of Surgeons' definition and 9 elements of informed decision-making using Braddock's validated scale. Uni- and bivariate analyses tested associations between decision outcomes as well as patient, consultation, and surgeon characteristics.ResultsOverall, surgeons discussed more elements of informed consent than informed decision-making. They most frequently described the nature of the illness, the operation, and potential complications, but were less likely to assess patient understanding. When a final treatment decision was deferred, surgeons were more likely to discuss elements of informed decision-making focusing on uncertainty (50% vs 15%, p = 0.006) and treatment alternatives (63% vs 27%, p = 0.02). Conversely, when surgery was scheduled, surgeons completed more elements of informed consent. These results were not associated with the presence of family, history of previous surgery, location, or surgeon specialty.ConclusionsSurgeons routinely discuss components of informed consent with patients before high-risk surgery. However, surgeons often fail to review elements unique to informed decision-making, such as the patients' role in the decision, their daily life, uncertainty, understanding, or patient preference.Copyright © 2021 American College of Surgeons.
