Falls occur in 28% of hemodialysis patients and increase the risk of physical impairment, morbidity, and mortality. Therefore, it is likely that kidney transplantation (KT) candidates with recurrent falls are less likely to access KT and more likely to experience adverse post-KT outcomes.
We used a 2-center cohort study of KT candidates (n = 3666) and recipients (n = 770) (January 2009 to January 2018). Among candidates, we estimated time to listing, waitlist mortality, and transplant rate by recurrent falls (≥2 falls) before evaluation using adjusted regression. Among KT recipients, we estimated risk of mortality, graft loss, and length of stay by recurrent falls before KT using adjusted regression.
Candidates with recurrent falls (6.5%) had a lower chance of listing (adjusted hazard ratio [aHR] = 0.68, 95% confidence interval [CI], 0.56-0.83) but not transplant rate; waitlist mortality was 31-fold (95% CI, 11.33-85.93) higher in the first year and gradually decreased over time. Recipients with recurrent falls (5.1%) were at increased risk of mortality (aHR = 51.43, 95% CI, 16.00-165.43) and graft loss (aHR = 33.57, 95% CI, 11.25-100.21) in the first year, which declined over time, and a longer length of stay (adjusted relative ratio [aRR] = 1.13, 95% CI, 1.03-1.25). In summary, 6.5% of KT candidates and 5.1% of recipients experienced recurrent falls which were associated with adverse pre- and post-KT outcomes.
While recurrent falls were relatively rare in KT candidates and recipients, they were associated with adverse outcomes. Transplant centers should consider employing fall prevention strategies for high-risk candidates as part of comprehensive prehabilitation.
在血液透析患者中,有 28%的患者会发生跌倒,这增加了身体损伤、发病率和死亡率的风险。因此,有反复跌倒史的肾移植(KT)候选者可能不太可能接受 KT,并且更有可能在接受 KT 后出现不良结局。
我们使用了一项针对 KT 候选者(n=3666)和接受者(n=770)的 2 中心队列研究(2009 年 1 月至 2018 年 1 月)。在候选者中,我们使用调整后的回归估计了在评估前有反复跌倒(≥2 次跌倒)的患者的列入名单时间、候补名单死亡率和移植率。在 KT 接受者中,我们使用调整后的回归估计了 KT 前反复跌倒与死亡率、移植物丢失和住院时间之间的关系。
有反复跌倒(6.5%)的候选者列入名单的机会较低(调整后的危险比[aHR] = 0.68,95%置信区间[CI],0.56-0.83),但移植率没有差异;在第一年内,候补名单死亡率是 31 倍(95% CI,11.33-85.93),随着时间的推移逐渐降低。有反复跌倒(5.1%)的接受者在第一年内的死亡率(aHR = 51.43,95% CI,16.00-165.43)和移植物丢失(aHR = 33.57,95% CI,11.25-100.21)的风险增加,随着时间的推移而降低,并且住院时间更长(调整后的相对比值[aRR] = 1.13,95% CI,1.03-1.25)。总之,6.5%的 KT 候选者和 5.1%的接受者经历了反复跌倒,这与 KT 前后的不良结局有关。
尽管 KT 候选者和接受者中反复跌倒的情况相对较少,但它们与不良结局有关。移植中心应考虑为高危候选者实施跌倒预防策略,作为综合康复前的一部分。
