BACKGROUND There is a growing recognition of the significance of the diasporic dimension of medical travel. Explanations of medical tourism are increasingly presented in a wider context of transnationalism, diaspora and migration. Yet diaspora and cross-border travellers rarely get through the broader narrative of medical travel. OBJECTIVE Our aim in this scoping review was to extend the current knowledge on the emerging subject of diasporic travels for medical purposes. Specifically, we reviewed the existing literature on what is known about the determinants and motivational factors of diasporic medical tourism; its geographic scope and its quantitative estimation. METHODS Using a scoping review methodology, we conducted the search in seven electronic databases. It resulted in 210 records retrieved. Ultimately, 28 research papers and 6 non-research papers (published between 2002 and 2019) met the following criteria: 1) focus on healthcare and health-related practices, 2) transnational perspective, 3) healthcare consumption in the country of origin (homeland) while being a resident of another country, 4) published in English. RESULTS The findings from our review highlighted the importance of diasporic medical patients who had been researched and analysed on four continents. Even though quantitative evidence has been scarce, the data analysed in the scoping review pointed to the existence of non-negligible level of diasporic medical tourism in Northern America, and in Europe. Various motivational factors were enumerated with their frequency of occurrence: medical culture (12), time availability ("by the way of being home") (9), communication (6), dissatisfaction with the current system (6), healthcare insurance status (5), quality of healthcare (5), second opinion (3), and value for money (3). CONCLUSION Diasporic medical tourists constitute an attractive segment of consumers that is still not well understood and targeted. They are part of transnational communities that cultivate the links between the two nations. They simultaneously participate in bi-lateral healthcare systems via return visits which impact the health systems of sending and receiving countries in a substantial way. In the current globalised, connected and migratory context, transnationalism seems to represent an answer to many local healthcare-related barriers. Sending and receiving countries have put in place an array of programmes and policies addressed to the diasporic medical travellers.

流离失所的医疗旅游：定量和定性证据的范围回顾。

背景技术人们越来越认识到医疗旅行的渗流维度的重要性。在跨国主义，散居和移民的更广泛背景下，越来越多地提出对医疗旅游的解释。然而，散居和跨境旅行的旅行者很少能从更广泛的医疗旅行叙述中解脱出来。目的我们在此范围界定审查中的目的是扩展有关新兴的医疗用途流散旅行的知识。具体来说，我们回顾了有关流散医疗旅游的决定因素和动机因素的现有文献。其地理范围及其定量估算。方法我们使用范围审查方法，在七个电子数据库中进行了搜索。结果检索到210条记录。最终，28篇研究论文和6篇非研究论文（于2002年至2019年之间发表）符合以下标准：1）专注于医疗保健和与健康相关的做法，2）跨国视角，3）原籍国（家园）的医疗保健消费而是另一个国家的居民，4）以英文出版。结果我们审查的结果强调了在四大洲进行过研究和分析的流散性医学患者的重要性。尽管缺乏定量证据，但范围界定审查中分析的数据指出，北美和欧洲存在着不可忽视的散逸医疗旅游水平。列举了各种动机因素及其发生频率：医学文化（12），时间可利用性（“在家的方式”）（9），沟通（6），对当前系统的不满意（6），医疗保险状况（5），医疗质量（5），第二意见（3）和物有所值（3）。结论流散性医疗游客构成了一个吸引人的细分受众群，但仍然没有得到很好的理解和针对性。它们是建立两国之间联系的跨国社区的一部分。他们通过回访同时参与双边医疗保健系统，这在很大程度上影响了发送国和接收国的医疗系统。在当前的全球化，联系和移民背景下，跨国主义似乎是对许多与当地医疗保健相关的障碍的解答。发送国和接收国已经制定了针对流散医疗旅行者的一系列计划和政策。对当前系统的不满意（6），医疗保险状况（5），医疗质量（5），第二意见（3）和物有所值（3）。结论流散性医疗游客构成了一个吸引人的细分受众群，但仍然没有得到很好的理解和针对性。它们是建立两国之间联系的跨国社区的一部分。他们通过回访同时参与双边医疗保健系统，这在很大程度上影响了发送国和接收国的医疗系统。在当前的全球化，联系和移民背景下，跨国主义似乎是对许多与当地医疗保健相关的障碍的解答。发送国和接收国已经制定了针对流散医疗旅行者的一系列计划和政策。对当前系统的不满意（6），医疗保险状况（5），医疗质量（5），第二意见（3）和物有所值（3）。结论流散性医疗游客构成了一个吸引人的细分受众群，但仍然没有得到很好的理解和针对性。它们是建立两国之间联系的跨国社区的一部分。他们通过回访同时参与双边医疗保健系统，这在很大程度上影响了发送国和接收国的医疗系统。在当前的全球化，联系和移民背景下，跨国主义似乎是对许多与当地医疗保健相关的障碍的解答。发送国和接收国已经制定了针对流散医疗旅行者的一系列计划和政策。
