临床试验中病人获益的评估——应该由医生还是由病人评估?这重要吗?
Assessing patients' improvement in clinical trials --Should the doctor or patient judge improvement and does it matter?
摘要
医生需要从病人的角度理解新疗法的获益,因为他们必须判断向病人提供这些疗法的相对风险和获益。健康状况评价应满足这种需求。目前已开发出了数种有效、可靠、对治疗敏感的由病人完成的测评工具。这些工具为了解某种治疗对预后的影响提供了宝贵线索,例如对功能和生活质量等的影响。对病人而言,功能和生活质量可能比单纯生存更为重要。然而,对某些情况,目前尚无测量特定疾病健康状况的指标,此时则需进行临床变化的整体评估。
