Lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH) are a common condition in men, and their incidence increases with age. The objective of this study was to evaluate the potential cost-utility of microwave thermotherapy, specifically the ProstaLund Feedback Treatment (PLFT), versus alpha-blockade in Swedish patients with LUTS due to BPH.
A health-economic simulation model, based on long-term disease progression and costs, was developed to analyse the cost-utility of PLFT in comparison with alpha-blockade over a 3-year period based on data from published literature, treatment programmes and official price lists. Outcome measures used in the analysis were quality of life, survival and reduction in International Prostate Symptom Score. Sensitivity analyses were performed for a number of essential variables. The perspective of the study is the healthcare sector. All costs are expressed as 2003 prices.
Three years after an intervention with PLFT or initiation of drug treatment the cost-utility of PLFT was estimated at approximately euro 6600-9500 per quality-adjusted life-year gained. The cost-utility was further improved over a longer time period, and PLFT appears to be cost-saving after 5 years. One important finding from the model simulation was that PLFT also seems to be favourable in patients with less pronounced symptoms. This result may be further validated when additional results from controlled clinical trials become available.
The present model simulation indicates that treatment with PLFT seems to be cost-effective compared with drug therapy with alpha-blockade. The result shows that the time-frame of the analysis has a great impact on the cost-effectiveness ratio.
良性前列腺增生(BPH)所致下尿路症状(LUTS)在男性中较为常见,且发病率随年龄增长而升高。本研究的目的是评估微波热疗,特别是前列腺隆德反馈治疗(PLFT),与α受体阻滞剂相比,对瑞典BPH所致LUTS患者的潜在成本效益。
基于长期疾病进展和成本建立了一个健康经济模拟模型,根据已发表文献、治疗方案和官方价格表中的数据,分析PLFT与α受体阻滞剂在3年期间的成本效益。分析中使用的结果指标为生活质量、生存率和国际前列腺症状评分的降低。对一些关键变量进行了敏感性分析。本研究的视角是医疗保健部门。所有成本均以2003年价格表示。
在接受PLFT干预或开始药物治疗三年后,PLFT的成本效益估计约为每获得一个质量调整生命年6600 - 9500欧元。在更长的时间段内,成本效益进一步提高,PLFT在5年后似乎具有成本节约效益。模型模拟的一个重要发现是,PLFT在症状较轻的患者中似乎也具有优势。当有更多对照临床试验结果时,这一结果可能会得到进一步验证。
目前的模型模拟表明,与α受体阻滞剂药物治疗相比,PLFT治疗似乎具有成本效益。结果表明,分析的时间框架对成本效益比有很大影响。
