The Dietary Approach to Stop Hypertension (DASH) and potassium supplementation have been shown to reduce the risk of death with a functioning graft (DWFG) and renal graft failure in renal transplant recipients (RTR). Unfortunately, a key problem for patients is the adherence to these diets. The aim of this study is to evaluate the cost-effectiveness and budget impact of higher adherence to either the DASH or potassium supplementation.
A Markov model was used to simulate the life course of 1000 RTR in the Netherlands. A societal perspective with a lifetime time horizon was used. The potential effect of improvement of dietary adherence was modelled in different scenarios. The primary outcomes are the incremental cost-effectiveness ratio (ICER) and the budget impact.
In the base case, improved adherence to the DASH diet saved 27,934,786 and gained 1880 quality-adjusted life years (QALYs). Improved adherence to potassium supplementation saved €1,217,803 and gained 2901 QALYs. Both resulted in dominant ICERs. The budget impact over a five-year period for the entire Dutch RTR population was €8,144,693.
Improving dietary adherence in RTR is likely to be cost-saving and highly likely to be cost-effective compared to the current standard of care in the Netherlands.
通过饮食控制高血压法（DASH）和钾补充已被证明可以降低肾移植受者（RTR）的移植物功能障碍（DWFG）和肾功能衰竭的死亡风险。不幸的是，患者面临的一个关键问题是对这些饮食的坚持。本研究旨在评估提高 DASH 或钾补充剂的依从性的成本效益和预算影响。
使用马尔可夫模型模拟了荷兰 1000 名 RTR 的生命过程。采用了终生时间范围的社会视角。在不同情况下，对改善饮食依从性的潜在影响进行了建模。主要结果是增量成本效益比（ICER）和预算影响。
在基线情况下，改善 DASH 饮食的依从性可节省 27934786 欧元，并获得 1880 个质量调整生命年（QALY）。改善钾补充剂的依从性可节省 1217803 欧元，并获得 2901 个 QALY。两者均产生了主导的 ICER。在五年内，整个荷兰 RTR 人群的预算影响为 8144693 欧元。
与荷兰目前的标准治疗相比，提高 RTR 的饮食依从性可能具有成本效益，而且很可能是具有成本效益的。
