The role of family doctors has become more and more important as people's demand for healthcare increases. However, there are still some problems in the implementation of family doctor contracting service, such as the difficulty of finding suitable family doctors and the difficulty of data sharing.

Develop a GIS-based Family Doctor Contract Service WeChat Mini Program (hereinafter referred to as the WeChat Mini Program), and complete the usability evaluation to provide residents with a faster and more efficient family doctor contracting service, and for the promotion of the application of mHealth technology in family doctor contracting service.

From January to June in 2022 through literature review to understand the residents' demand for family doctor contracting service and the development of WeChat applet; on-site survey of 200 community residents using random sampling method to analyze the residents' demand for WeChat applet; focusing on the design ideas and function orientation of WeChat applet, four focus group interviews were conducted with the residents, family doctors, administrators, and technicians; based on the demand analysis and the development elements, the development elements of WeChat applet were constructed. Four focus group interviews were conducted; based on the demand analysis and design ideas, the development elements of the WeChat applet were constructed. From June to August in 2022, a field survey was conducted on 96 users of the WeChat Mini Program using the System Usability Scale (SUS). Additionally, usability evaluation of the WeChat Mini Program was performed through key informant interviews and expert consultations.

The main needs of residents for WeChat applets included health consultation (78.00%), quick location of nearby family doctors (75.00%), and health science popularization (71.50%). The design scheme of the WeChat applet covered the core functions of path planning and navigation, information query and display, residents' health management, online contracting and renewal, and online consultation; after the trial operation of the WeChat applet, the usability analysis was conducted, and the average score of SUS was (78.62±9.23), suggesting that the WeChat applet was practically operable and easy to learn.

The connotation of family doctor contracting service based on the GIS platform and the use of multifaceted thinking can ensure the scientificity and usability of WeChat applet development.

随着人们对医疗保健的需求增加，家庭医生的角色变得越来越重要。然而，目前家庭医生签约服务在实施过程中还存在一些问题，如寻找合适的家庭医生难、数据共享难等。

开发一个基于地理信息系统（GIS）的家庭医生签约服务微信小程序（以下简称微信小程序），并完成可用性评价，为居民提供更为快捷、高效的家庭医生签约服务，以促进移动医疗技术在家庭医生签约服务的应用。

2022年1—6月通过文献回顾了解居民对家庭医生签约服务的需求及微信小程序开发情况；采用随机抽样法对200名社区居民进行现场调查，分析居民对微信小程序的需求；围绕微信小程序的设计思路与功能定位，对居民、家庭医生、管理者和技术人员进行了4次焦点小组访谈；基于需求分析和设计思路，构建微信小程序的开发要素。2022年6—8月通过对96名微信小程序用户采用系统可用性量表（SUS）进行现场调查，并通过关键知情人访谈及专家咨询对微信小程序进行可用性评价。

居民对微信小程序的主要需求包括健康咨询（78.00%）、快速定位附近家庭医生（75.00%）和健康科普（71.50%）；微信小程序的设计方案涵盖了路径规划和导航、信息查询与展示、居民健康管理、在线签约与续约、在线咨询等核心功能；对微信小程序试运营后，进行可用性分析，SUS平均得分为（78.62±9.23）分，提示该款微信小程序具有实际可操作性和易学性。

基于GIS平台的家庭医生签约服务内涵以及运用多元思维，能够确保微信小程序开发的科学性和可用性。
