Patients facing difficult decisions often ask physicians for recommendations. However, little is known regarding the ways that physicians' decisions are influenced by the act of making a recommendation.
We surveyed 2 representative samples of US primary care physicians-general internists and family medicine specialists listed in the American Medical Association Physician Masterfile-and presented each with 1 of 2 clinical scenarios. Both involved 2 treatment alternatives, 1 of which yielded a better chance of surviving a fatal illness but at the cost of potentially experiencing unpleasant adverse effects. We randomized physicians to indicate which treatment they would choose if they were the patient or they were recommending a treatment to a patient.
Among those asked to consider our colon cancer scenario (n = 242), 37.8% chose the treatment with a higher death rate for themselves but only 24.5% recommended this treatment to a hypothetical patient (χ(2)(1) = 4.67, P = .03). Among those receiving our avian influenza scenario (n = 698), 62.9% chose the outcome with the higher death rate for themselves but only 48.5% recommended this for patients (χ(2)(1) = 14.56, P < .001).
The act of making a recommendation changes the ways that physicians think regarding medical choices. Better understanding of this thought process will help determine when or whether recommendations improve decision making.
面临艰难决策的患者常常向医生寻求建议。然而,关于医生的决策如何受到提供建议这一行为的影响,我们知之甚少。
我们对美国基层医疗医生的两个代表性样本——美国医学协会医师主文件中列出的普通内科医生和家庭医学专家——进行了调查,并向他们分别呈现两种临床情景中的一种。两种情景均涉及两种治疗方案,其中一种方案有更好的机会在致命疾病中存活,但代价是可能会经历不愉快的不良反应。我们随机安排医生表明,如果他们是患者会选择哪种治疗,或者他们会向患者推荐哪种治疗。
在被要求考虑结肠癌情景的医生中(n = 242),37.8%的医生为自己选择了死亡率更高的治疗方案,但只有24.5%的医生向假设的患者推荐了这种治疗(χ(2)(1)=4.67,P = 0.03)。在接受禽流感情景的医生中(n = 698),62.9%的医生为自己选择了死亡率更高的结果,但只有48.5%的医生向患者推荐了这个结果(χ(2)(1)=14.56,P < 0.001)。
提供建议的行为改变了医生对医疗选择的思考方式。更好地理解这一思维过程将有助于确定建议何时或是否能改善决策。
