Eliciting Population Preferences for Mass Colorectal Cancer Screening Organization
Introduction . The implementation of mass colorectal cancer ( CRC ) screening is a public health priority . Population participation is fundamental for the success of CRC screening as for any cancer screening program . The preferences of the population may influence their likelihood of participation . Objectives . The authors sought to elicit population preferences for CRC screening test characteristics to improve the design of CRC screening campaigns . Methods . A discrete choice experiment was used . Question naires were compiled with a set of pairs of hypothetical CRC screening scenarios . The survey was conducted by mail from June 2006 to October 2006 on a representative sample of 2000 inhabitants , aged 50 to 74 years from the northwest of France , who were r and omly selected from electoral lists . Question naires were sent to 2000 individuals , each of whom made 3 or 4 discrete choices between hypothetical tests that differed in 7 attributes : how screening is offered , process , sensitivity , rate of unnecessary colonoscopy , expected mortality reduction , method of screening test result transmission , and cost . Results . Complete responses were received from 656 individuals ( 32.8 % ) . The attributes that influenced population preferences included expected mortality reduction , sensitivity , cost , and process . Participants from high social classes were particularly influenced by sensitivity . Conclusions . The results demonstrate that the discrete choice experiment provides information on patient preferences for CRC screening : improving screening program effectiveness , for instance , by improving test sensitivity ( the most valued attribute ) would increase satisfaction among the general population with regard to CRC screening programs . Additional studies are required to study how patient preferences actually affect adherence to regular screening programs
