摘要

开展早期经济学评估（EEE），评估GS在降低RoF和FoF方面的成本效益。成本效益分析采用了最相关的参数，如步速的增加和FoF的降低，来估算RoF的降低、对所使用的医疗资源的影响以及对英国国家卫生系统的财务影响。根据RoF和FoF的降低情况，以每质量调整生命年（QALYs）的增量成本效益比来衡量结果。成本效益分析结果表明，与标准护理相比，GS 是改善跌倒或害怕跌倒的老年人行动的主要策略（基于 FoF 的增量 QALYs = 0.77，基于 RoF 的增量 QALYs = 1.07，FoF 的成本 = -4479.57 英镑，RoF 的成本 = -2901.79 英镑）。通过实施 GS，投资回报率结果表明，基于 RoF 的降低，投资于 GS 的每英镑可为每位患者节省 1.85 英镑的成本，基于 FoF 的降低，可为每位患者节省 11.16 英镑的成本。根据迭代次数计算的成本节约概率分别为 79.4%（基于 FoF）和 100%（基于 RoF）。

Early economic evaluation of the digital gait analysis system for fall prevention–Preliminary analysis of the GaitSmart system

Objective

To develop an early economics evaluation (EEE) to assess the cost-effectiveness of the GS in reducing the RoF and FoF.

Methods

A cost-effectiveness analysis (CEA) with a return on investment (RoI) estimation was performed. CEA used the most relevant parameters, such as increased gait speed and decreased FoF, to estimate the reduction in the RoF, the impact on health care resources used and financial implications for the National Health System in the United Kingdom. Outcomes were measured as incremental cost-effectiveness ratio per quality-adjusted life years (QALYs) gained based on the reduction of the RoF and FoF. Uncertainties around the main parameters used were evaluated by probabilistic sensitivity analysis.

Results

The CEA results showed that the GS is a dominant strategy over the standard of care to improve the movements of older persons who have suffered a fall or are afraid of falling (incremental QALYs based on FoF = 0.77 and QALYs based on RoF = 1.07, cost of FoF = -£4479.57 and cost of RoF = -£2901.79). By implementing the GS, the ROI results suggest that every pound invested in the GS could result in cost savings of £1.85/patient based on the RoF reduction and £11.16/patient based on the FoF reduction. The probability of being cost saving based on the number of iterations were 79.4 percent (based on FoF) and 100 percent (based on RoF).
