title: [Cost analysis of the colorectal neoplasm screen program in Beijing].
abstract: OBJECTIVE
  To conduct with a cost analysis of the colorectal neoplasm screening program in Beijing, and provide data evidence for decision making.
  
  
  METHODS
  Based on stratified cluster sampling method, we carried out a 2-stage colorectal neoplasm screening program within 6 districts, Dongcheng, Xicheng, Chaoyang, Haidian, Fengtai and Shijingshan, of Beijing city between October, 2012 to May. 2013. The first stage of the program was to conducting a cancer risk level evaluation for community residents who were forty years older and the second stage's task was to providing clinical exam for those high risk people who were selected from the first stage. There were about 12 953 residents were involved in this program. We calculated the main cost of the colorectal neoplasm screen program in Beijing. Then estimate the cost of detecting one Colorectal Neoplasm patient of this program and compare it with the total treatment cost for a patient.
  
  
  RESULTS
  2 487 high risk residents were selected by the first stage and 1 055 of them made appointment for the colonoscopy exam but only 375 accepted the exam, participate rate was 35.5%. 9 neoplasm cancer patients and 71 pre-cancer patient were found at the second stage, the detection rate were 69.2/100 000 and 546/100 000, respectively. The direct input for this neoplasm screening program was 227 100 CNY and the transport expense was 4 200 CNY in the calculations. The cost for detecting one cancer patient was about 19 900 CNY. Comparing with the total medical care cost of a cancer patient (1 282 800 CNY), especially for those have been diagnosed as middle to end stage cancer, the screening program (cost 842 800 CNY) might help to reduce the total health expenditure about 128 700 CNY, based on 12 953 local residents age above 40 years old.
  
  
  CONCLUSIONS
  An colonoscopy based colorectal neoplasm screening program showed its function on medical expenditure saving and might have advantage on health social labor creating.
