An economic evaluation of reducing colorectal cancer surveillance intensity: supplementary data

These are peer-reviewed supplementary materials for the article 'An economic evaluation of reducing colorectal cancer surveillance intensity' published in the Journal of Comparative Effectiveness Research.Table 1: Parameters Used in the ModelTable 2: Distributions Used for Probabilistic Sensitivity AnalysisAim: Analyze the impact of national implementation of ‘low intensity’ post-treatment colorectal cancer surveillance compared with current practices. Materials & methods: Create a population-level Markov model to estimate impacts of expansion of low versus high intensity surveillance post-treatment on healthcare utilization, costs and caregiver time loss. Results: Shifting to low intensity colorectal cancer surveillance would reduce patient burden by 301,830 h per patient annually over 5 years. Cost reductions over 5 years were US$43.5 million for Medicare and US$4.2 million for Medicaid. Total societal cost savings equaled US$104.2 million. Conclusion: National implementation of low intensity post-treatment colorectal cancer surveillance has the potential to significantly reduce burden and costs on patients and their caregivers with no added risks to health.

本数据集为发表于《比较疗效研究杂志》的论文《降低结直肠癌监测强度的经济评估》的同行评审补充材料。表1：模型中使用的参数；表2：用于概率敏感性分析的分布。研究目的：分析在全国范围内实施‘低强度’治疗后结直肠癌监测与现行做法相比的影响。研究材料与方法：构建一个基于人群水平的马尔可夫模型，以估计扩大低强度与高强度治疗后监测对医疗保健利用、成本及护理者时间损失的影响。研究结果：转向低强度结直肠癌监测将在五年内每年降低每位患者301,830小时的时间负担。五年内，对医疗保险而言，成本降低约为4350万美元，对医疗补助而言，成本降低约为420万美元。总的社会成本节约达1.042亿美元。研究结论：在全国范围内实施低强度治疗后结直肠癌监测具有显著减轻患者及其护理者负担和成本，同时不增加健康风险的潜力。
