PURPOSES The purposes of this discrete choice experiment are as follows: (1) to investigate the preferences of gastric cancer survivors for follow-up care, and (2) to quantify the importance of follow-up care-related characteristics that may affect the gastric cancer survivors' choices of their follow-up, so as to provide references for the development of the follow-up strategy of gastric cancer survivors. METHODS Discrete choice experimental design principle was applied to develop the survey instrument. All questionnaires were filled out by the respondents and collected on site. A mixed logit model was used to estimate gastric cancer survivors' preferences. Willingness to pay estimates and simulations of follow-up uptake rates were calculated. RESULTS All six attributes are significantly important for the follow-up care of gastric cancer survivors (p < 0.05). Achieving very thorough follow-up contents was the most valued attribute level (coefficient = 1.995). Specialist doctors are the most preferred providers followed by specialist nurses, and gastric cancer survivors were willing to pay more for these attribute levels. Changes in attribute levels affected uptake rate of follow-up. When the multiple attribute levels were changed at the same time, a very thorough follow-up content was provided by the same specialist doctor (specialist nurse), and the probability of receiving follow-up increases by 95.82% (94.90%). CONCLUSIONS The characteristics of follow-up care in our study reflect the health management services' expectations of gastric cancer survivors. A dedicated specialist nurse involved in follow-up care should be developed to contribute to solve the complex and multifaceted personal needs of gastric cancer survivors.

胃癌幸存者对随访护理的偏好——一项多中心离散选择实验研究。

目的 该离散选择实验的目的如下：(1) 调查胃癌幸存者对后续护理的偏好，以及 (2) 量化可能影响胃癌的后续护理相关特征的重要性。癌症幸存者的随访选择，为制定胃癌幸存者的随访策略提供参考。方法应用离散选择实验设计原则研制调查仪器。所有问卷均由受访者填写并现场收集。使用混合 logit 模型来估计胃癌幸存者的偏好。计算愿意支付的估计和后续吸收率的模拟。结果 所有六个属性对于胃癌幸存者的后续护理都非常重要（p < 0.05）。实现非常彻底的后续内容是最有价值的属性级别（系数= 1.995）。专科医生是最受青睐的提供者，其次是专科医生，胃癌幸存者愿意为这些属性水平支付更多费用。属性水平的变化影响了后续的吸收率。当多个属性等级同时变化时，由同一位专科医生（专科护士）提供了非常彻底的随访内容，接受随访的概率提高了95.82%（94.90%）。结论 本研究中随访护理的特点反映了胃癌幸存者对健康管理服务的期望。
