Research has shown that physicians are poor predictors of patients' life-sustaining treatment preferences. Our study examined the association between three aspects of physician experience and their ability to accurately predict patients' preferences for two different life-sustaining treatments in the event of two serious medical conditions.
Seventeen physicians predicted the treatment preferences of 57 patients and then interviewed patients regarding their actual treatment preferences. Physicians' professional experience, length of their relationship with the patient, and experience with direct feedback were measured to determine the association of these factors with the accuracy of the physicians' predictions.
Physicians became more accurate predictors as they interviewed more patients and received direct feedback regarding the accuracy of their predictions (P < .001). Residents were more accurate than faculty in predicting patients' preferences (P < .05).
Increased experience with life-sustaining treatment discussions improved the physicians' abilities to accurately predict patient preferences. Although possibly resulting from small sample size, neither greater professional experience nor longer relationship with a patient improved the accuracy of physicians' predictions. Future research should examine whether discussing end-of-life issues with patients more often makes physicians more sensitive predictors of patients' life-sustaining treatment preferences.
研究表明,医生很难准确预测患者对维持生命治疗的偏好。我们的研究调查了医生经验的三个方面与他们在两种严重疾病情况下准确预测患者对两种不同维持生命治疗的偏好能力之间的关联。
17名医生预测了57名患者的治疗偏好,然后就患者的实际治疗偏好进行了访谈。测量了医生的专业经验、与患者关系的时长以及接受直接反馈的经验,以确定这些因素与医生预测准确性之间的关联。
随着医生访谈的患者增多并收到关于其预测准确性的直接反馈,他们的预测变得更加准确(P < .001)。住院医生在预测患者偏好方面比教员更准确(P < .05)。
增加维持生命治疗讨论的经验提高了医生准确预测患者偏好的能力。尽管可能是由于样本量小,但无论是更丰富的专业经验还是与患者更长时间的关系,都没有提高医生预测的准确性。未来的研究应探讨更频繁地与患者讨论临终问题是否会使医生成为患者维持生命治疗偏好更敏锐的预测者。
