The purposes of this discrete choice experiment are as follows: (1) quantify the relevant characteristics that may affect the follow-up selection of gastric cancer patients after surgery and (2) explore the differences in follow-up preferences of gastric cancer patients at different stages and reveal the change trend of preferences over time, thereby providing references for the formulation and optimization of follow-up strategies.
A survey instrument that was developed using the design principle of a discrete choice experiment investigated gastric cancer patients on the day of discharge, and at 3 months, 6 months, and 12 months after discharge. In Stata 15.0, a mixed logit model was used to explore the preferences of gastric cancer patients after surgery at different stages, the willingness to pay was calculated, and the NLCOM command was used to simulate the follow-up uptake rates of different attribute levels at different stages.
On the day of discharge, and 3 months, 6 months, and 12 months after discharge, the most important attribute levels of gastric cancer patients after surgery were "thoroughness-very thorough," "method-face-to-face," "thoroughness-very thorough," and "provider-specialist nurse," respectively, and patients were willing to pay more for these services. Patients' preference for the attribute level "very thorough" decreased over time, while their preferences for "specialist doctors" as follow-up providers remained relatively stable. Furthermore, the attribute levels with the greatest effect on receiving the baseline follow-up program varied across stages.
The gastric cancer patients' preferences for follow-up change over time, and the time factor should be considered when developing follow-up strategies.
本离散选择实验的目的如下：（1）量化可能影响胃癌患者术后随访选择的相关特征；（2）探究不同阶段胃癌患者随访偏好的差异，揭示偏好随时间的变化趋势，从而为随访策略的制定和优化提供参考。
采用离散选择实验的设计原则开发的调查问卷，在出院当天以及出院后3个月、6个月和12个月对胃癌患者进行调查。在Stata 15.0中，使用混合逻辑模型探究不同阶段胃癌患者术后的偏好，计算支付意愿，并使用NLCOM命令模拟不同阶段不同属性水平的随访接受率。
在出院当天以及出院后3个月、6个月和12个月，胃癌患者术后最重要的属性水平分别为“彻底程度-非常彻底”“方式-面对面”“彻底程度-非常彻底”和“提供者-专科护士”，患者愿意为这些服务支付更多费用。患者对“非常彻底”属性水平的偏好随时间下降，而对“专科医生”作为随访提供者的偏好相对稳定。此外，对接受基线随访方案影响最大的属性水平在不同阶段有所不同。
胃癌患者对随访的偏好随时间变化，在制定随访策略时应考虑时间因素。
