Cost-effectiveness analysis of a community-based colorectal cancer screening program in Shanghai, China.

Objective: This study investigated the cost-effectiveness of a community-based colorectal cancer-screening program (C-CRCSP) in Shanghai, China, among the residents in the urban, suburban and rural areas.

Methods: A Markov model was constructed to evaluate the cost-effectiveness of a 25-year annual C-CRCSP including 100 000 populations. Cost-effectiveness was determined by the incremental cost-effectiveness ratio (ICER); referring to either life-years gained, or quality-adjusted life-years (QALYs) gained.
