Abstract
AIM

To measure the willingness to pay for colorectal cancer screening in Guangzhou, and to identify those factors associated with it.

METHODS

A face-to-face questionnaire survey for pre-screening population from free and non-free colonoscopy districts was used to collect information on demographic characteristics, health behaviours, the intention of the cancer screenings and willingness to pay for colorectal cancer screening. A total of 1243 participants who took part in the pre-screening for colorectal cancer in Guangzhou were collected in the study. Categorical data were compared using the χ2 test to analyse significant differences. Non-conditional logistic regression and multi-class logistic regression were also performed for multivariate analysis and to estimate the odds ratios.

RESULTS

The percentage of participants willing to pay for colorectal cancer screening was 91.7%. “Unnecessary” was the dominant reason that participants gave for their unwillingness, accounting for 63.1%. Of those who were willing to pay, 29.2%, 20.7%, 14.8%, 13.0% and 22.4% of participants were willing to pay less than \100, \100-\199, \200-299, \300-\399 and more than \400, respectively. Non-logistic regression analysis showed that respondents who were male, had a high level of education, were from the family with more children/older to raise, and accepted colorectal cancer screening were willing to pay for this screening. Multi-class logistic regression analysis showed that respondents with higher annual household income per capita, from government and private enterprises, government agency/institution and peasants, and less family medical expenditure were willing to pay more.

CONCLUSION

Willingness to pay for colorectal cancer screening in Guangzhou is high, but the amount of willing to pay is not much.

Core tip: The uptake of colorectal cancer screening is very important for the screening effect. For a mass screening program, however, it is not possible to offer the screenings free of charge. This study was conducted to measure the willingness to pay for colorectal cancer screening in Guangzhou and to identify those factors associated with it. There were 1243 participants collected in the study. The percentage of participants willing to pay for colorectal cancer screening was high, but the amount of willing to pay was not much, and less than the cost of colonoscopy.
