Socioeconomic and ethnic inequity in access to kidney transplant waiting list has been described in the United States but not examined in a universal healthcare system.
Eleven thousand two hundred ninety-nine patients aged 18 to 69 years starting renal replacement therapy (January 1, 1997 to December 31, 2004) in England and Wales were included. Multivariable Cox proportional hazards models were used to assess time to activation on the transplant waiting list for socially deprived patients among white patients. The effect of ethnic origin (South Asians and blacks compared with whites) was examined among all patients.
Among white patients, in the fully adjusted model, the hazard ratio (HR) for the most deprived quintile was 0.60 (95% confidence interval [CI] 0.54-0.68, P trend <0.0001) compared with the least deprived. Deprivation effects were more pronounced among those 50 years and older (P value for interaction <0.0001). Non-whites had a lower risk of being waitlisted than whites (for blacks: HR 0.89, 95% CI 0.79-1.01; for South Asians: HR 0.91, 95% CI 0.83-0.99, P value for heterogeneity=0.03). These differences were attenuated in a fully adjusted model. However non-whites who were 50 years and older were more likely to be transplant waitlisted than whites (interaction P=0.002).
Individuals living in socially deprived areas have reduced access to the transplant waiting list. Understanding the reasons for this apparent inequity is important if we wish to ensure equitable access to renal transplants. There were no major differences by ethnicity, and if anything, older white patients were less likely to be waitlisted.
在美国,人们已经描述了在获得肾脏移植等候名单方面存在的社会经济和种族不平等现象,但在全民医疗保健体系中尚未对此进行研究。
本研究纳入了 1997 年 1 月 1 日至 2004 年 12 月 31 日期间在英格兰和威尔士开始接受肾脏替代治疗的 1299 名年龄在 18 至 69 岁的患者。使用多变量 Cox 比例风险模型来评估社会贫困患者在白人患者中在移植等候名单上获得激活的时间。还在所有患者中检查了种族起源(南亚人和黑人与白人相比)的影响。
在白人患者中,在完全调整的模型中,最贫困五分位数的危险比(HR)为 0.60(95%置信区间[CI] 0.54-0.68,P 趋势<0.0001),与最不贫困的五分位数相比。在 50 岁及以上的人群中,贫困的影响更为明显(交互作用 P 值<0.0001)。与白人相比,非白人患者被列入等候名单的风险较低(对于黑人:HR 0.89,95%CI 0.79-1.01;对于南亚人:HR 0.91,95%CI 0.83-0.99,P 值异质性=0.03)。在完全调整的模型中,这些差异有所减弱。然而,50 岁及以上的非白人患者比白人患者更有可能被列入移植等候名单(交互作用 P=0.002)。
生活在社会贫困地区的个人获得移植等候名单的机会减少。如果我们希望确保公平获得肾脏移植,那么了解这种明显的不平等现象的原因非常重要。种族之间没有明显差异,实际上,年龄较大的白人患者被列入等候名单的可能性较小。
