The headroom method was introduced for the very early evaluation of the potential value of new technologies. It allows for establishing a ceiling price for technologies to still be cost-effective by combining the maximum effect a technology might yield, the maximum willingness-to-pay (WTP) for this effect, and potential downstream expenses and savings. Although the headroom method is QALY-based, not all innovations are expected to result in QALY gain.
This study explores the feasibility and usefulness of the headroom method in the evaluation of technologies that are unlikely to result in QALY gain. This will be illustrated with the diagnostic trajectory of complex pediatric neurology (CPN).
Our headroom analysis showed a large room for improvement in the current diagnostic trajectory of CPN in terms of diagnostic yield. Combining this with a maximum WTP value for an additional diagnosis and the potential downstream expenses and savings, resulted in a total headroom of €15,028. This indicates that a new technology in this particular diagnostic trajectory, might be cost-effective as long as its costs do not exceed €15,028.
The headroom method seems a useful tool in the very early evaluation of medical technologies, also in cases when immediate QALY gain is unlikely. It allows for allocating healthcare resources to those technologies that are most promising. It should be kept in mind, however, that the headroom assumes an optimistic scenario, and for that reason cannot guarantee future cost-effectiveness. It might be most useful for ruling out those technologies that are unlikely to be cost-effective.
引入“空间法”是为了对新技术的潜在价值进行早期评估。它通过结合技术可能产生的最大效果、对这种效果的最大意愿支付(WTP)以及潜在的下游费用和节省,为技术设定一个仍然具有成本效益的上限价格。尽管空间法是基于 QALY 的,但并非所有创新都有望带来 QALY 的增加。
本研究探讨了空间法在评估不太可能带来 QALY 增益的技术时的可行性和有用性。这将通过复杂儿科神经病学(CPN)的诊断轨迹来说明。
我们的空间分析显示,CPN 当前诊断轨迹在诊断收益方面有很大的改进空间。将这一点与对额外诊断的最大 WTP 值以及潜在的下游费用和节省结合起来,得出总空间为 15028 欧元。这表明,在特定的诊断轨迹中,只要新技术的成本不超过 15028 欧元,它可能具有成本效益。
空间法似乎是一种非常有用的工具,可以在早期评估医疗技术,即使即时 QALY 增益不太可能。它可以将医疗资源分配给最有前途的技术。然而,应该记住,空间法假设了一个乐观的情景,因此不能保证未来的成本效益。它可能最有助于排除那些不太可能具有成本效益的技术。
