Outline
Toinvestigate population preferences and willingness to pay for colorectal cancer diagnostic strategies, andto provide evidence to optimize the initial screening and diagnosis service pathway and develop intervention strategies.
A discrete choice experiment was designed incorporating six attributes: appointment waiting time, number of healthcare visits, pre-diagnostic preparation, invasiveness, diagnostic accuracy, and out-of-pocket cost. In a central urban district of Shanghai, respondents were presented with a hypothetical scenario in which they had tested positive in an initial screening for colorectal cancer. Based on this scenario, their preferences for diagnostic strategies were elicited. A mixed logit model was subsequently employed to analyze population preferences and willingness to pay (WTP).
Appointment waiting time, pre-diagnostic preparation, invasiveness, diagnostic accuracy and out-of-pocket cost had significant effects on respondents’ choices of diagnostic strategies. Diagnostic accuracy was the most important attribute, accounting for 53.61% of relative importance. This was followed by pre-diagnostic preparation and invasiveness, which together accounted for 26.33%. Respondents were willing to pay an additional 623.50 RMB to switch from an invasive to a non-invasive diagnostic option.
Preferences for colorectal cancer diagnostic strategies are primarily driven by diagnostic accuracy, with trade-offs involving the absence of pre-diagnostic preparation, non-invasiveness, shorter appointment waiting times, and lower out-of-pocket costs. It is recommended that communities further strengthen health education on the accuracy of colonoscopy diagnosis, provide non-invasive diagnostic alternatives, and improve referral efficiency. These measures may enhance population adherence to diagnostic procedures, thereby improving the effectiveness of colorectal cancer screening programs and maximizing population health benefits.
