An economic evaluation of reducing colorectal cancer surveillance intensity

Abstract

Aim: 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.
