JAMA Intern Med:糖尿病患者对治疗负担的看法影响治疗获益

2014-07-02 CMT 中国医学论坛报CMT糖尿病微信

一项英美联合研究显示,改善血糖控制可带来明确益处,特别是对较年轻的患者。然而,对于大多数年龄>50岁、糖化血红蛋白(HbA1c)水平<9%、接受二甲双胍治疗的患者,强化降糖治疗带来的益处往往有限。治疗获益与患者对治疗负担的看法密切相关。论文6月26日在线发表于《美国医学会杂志·内科学》(JAMA Internal Medicine)。 该研究旨在评估在2型糖尿病患者中,治疗负担(tr

一项英美联合研究显示,改善血糖控制可带来明确益处,特别是对较年轻的患者。然而,对于大多数年龄>50岁、糖化血红蛋白(HbA1c)水平<9%、接受二甲双胍治疗的患者,强化降糖治疗带来的益处往往有限。治疗获益与患者对治疗负担的看法密切相关。

该研究旨在评估在2型糖尿病患者中,治疗负担(treatment burden)对强化降糖与中度降糖的影响差异。研究者用马尔科夫(Markov)模拟模型估计降低HbA1c对糖尿病转归和总体质量调整生命年(QALY)的影响。假设HbA1c水平>9%应常规接受治疗。模型概率基于对随机试验和观察性研究的估计值。模拟患者基于美国全国健康与营养调查研究的2型糖尿病患者。主要转归为QALY和糖尿病微血管及心血管并发症风险的降低。

结果为,假设治疗负担低(0.001,或每年损失0.4天),治疗每使HbA1c水平降低1%,可为45岁诊断糖尿病的模拟患者带来0.77~0.91 QALY的益处,为75岁诊断糖尿病的模拟患者带来0.08~0.10 QALY的益处。在75岁的患者中,治疗负担增加(0.01,或每年损失3.7天)导致HbA1c水平降低带来的害处大于益处。在所有年龄段,认为治疗负担更重(0.025~0.05)的患者会因降HbA1c治疗而导致QALY净损失。


“真正让我们感到意外的是,患者的结局多是以降低生活质量而告终——这主要是那些确诊较晚或确实不喜欢治疗的患者。”

研究者认为,目前广泛提倡的强化降糖治疗应予重新考虑,对于HbA1c水平<9%的患者,应权衡治疗益处估计值与患者对治疗负担的看法后,进行个体化治疗
