Effective risk communication about medical procedures is critical to ethical shared decision-making. Here, we explore the potential for development of an evidence-based lexicon for verbal communication of surgical risk. We found that Ear, Nose and Throat (ENT) surgeons expressed a preference for communicating such risks using verbal probability expressions (VPEs; e.g., "high risk"). However, there was considerable heterogeneity in the expressions they reported using (Study 1). Study 2 compared ENT surgeons' and laypeople's (i.e., potential patients) interpretations of the ten most frequent VPEs listed in Study 1. While both groups displayed considerable variability in interpretations, lay participants demonstrated more, as well as providing systematically higher interpretations than those of surgeons. Study 3 found that lay participants were typically unable to provide unique VPEs to differentiate between the ranges of (low) probabilities required. Taken together, these results add to arguments that reliance on VPEs for surgical risk communication is ill-advised. Not only are there systematic interpretational differences between surgeons and potential patients, but the coarse granularity of VPEs raises severe challenges for developing an appropriate evidence-based lexicon for surgical risk communication. We caution against the use of VPEs in any risk context characterized by low, but very different, probabilities. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

不太可能存在用于传达手术风险的适当语言概率词典。

关于医疗程序的有效风险沟通对于合乎道德的共同决策至关重要。在这里,我们探讨了开发用于手术风险口头交流的循证词典的潜力。我们发现耳鼻喉 (ENT) 外科医生更倾向于使用口头概率表达(VPE;例如“高风险”)来传达此类风险。然而,他们使用的表达方式存在相当大的异质性(研究 1)。研究 2 比较了 ENT 外科医生和非专业人士(即潜在患者)对研究 1 中列出的 10 种最常见 VPE 的解释。虽然两组在解释上表现出相当大的差异,但非专业参与者表现得更多,并且提供了比研究人员更高的系统解释外科医生。研究 3 发现,非专业参与者通常无法提供独特的 VPE 来区分所需的(低)概率范围。总而言之,这些结果增加了依赖 VPE 进行手术风险沟通的论点是不明智的。不仅外科医生和潜在患者之间存在系统性的解释差异,而且 VPE 的粗粒度对开发适当的基于证据的外科风险沟通词典提出了严峻挑战。我们告诫不要在任何以低概率但非常不同的概率为特征的风险环境中使用 VPE。(PsycInfo 数据库记录 (c) 2022 APA,保留所有权利)。这些结果进一步证明了依赖 VPE 进行手术风险沟通是不明智的。不仅外科医生和潜在患者之间存在系统性的解释差异,而且 VPE 的粗粒度对开发适当的基于证据的外科风险沟通词典提出了严峻挑战。我们告诫不要在任何以低概率但非常不同的概率为特征的风险环境中使用 VPE。(PsycInfo 数据库记录 (c) 2022 APA,保留所有权利)。这些结果进一步证明了依赖 VPE 进行手术风险沟通是不明智的。不仅外科医生和潜在患者之间存在系统性的解释差异,而且 VPE 的粗粒度对开发适当的基于证据的外科风险沟通词典提出了严峻挑战。我们告诫不要在任何以低概率但非常不同的概率为特征的风险环境中使用 VPE。(PsycInfo 数据库记录 (c) 2022 APA,保留所有权利)。我们告诫不要在任何以低概率但非常不同的概率为特征的风险环境中使用 VPE。(PsycInfo 数据库记录 (c) 2022 APA,保留所有权利)。我们告诫不要在任何以低概率但非常不同的概率为特征的风险环境中使用 VPE。(PsycInfo 数据库记录 (c) 2022 APA,保留所有权利)。
