Equitable access to healthcare services constitutes one of the leading priorities of healthcare provision and access to dialysis services (ADS) has an essential impact on patients depending on renal dialysis. The many existing GIS-based ADS evaluations include various spatial and non-spatial factors affecting ADS. We systematically mapped and reviewed the available literature with reference to this area identifying gaps in current GIS-based ADS measurements and developing recommendations for future studies. A threestep, systematic mapping review of the available GIS-related evidence in PubMed, Embase, Web of science, Scopus, Science Direct and IEEE Xplore was performed in May 2016 and the information collected updated October 2017 by two independent selection processes. The quality of the studies was assessed using an informal, mixed-approach scoring system. Out of 1119 literature references identified, 36 were identified and used for final review after removal of duplicates, study screenings and applying inclusion/exclusion criteria. Given the contents of the selected studies, three study groups were identified and 41 factors with potential effects on ADS determined. These studies mainly addressed the potential and/or spatial aspects of ADS. Our systematic mapping review of the evidence revealed that current GIS-based measures of ADS tend to calculate potential ADS instead of a realized one. It was also noted that listed factors affecting ADS were mainly nonspatial bringing forth the hypothesis that designing an integrated ADS index could possibly produce better ADS score than those currently advocated. Some primary and secondary research suggestions are made and a list of recommendations offered.
公平获得医疗服务是医疗保健提供的首要优先事项之一，而获得透析服务对依赖肾脏透析的患者具有至关重要的影响。现有的许多基于地理信息系统（GIS）的透析服务评估包括影响透析服务的各种空间和非空间因素。我们系统地绘制并回顾了该领域的现有文献，找出了当前基于GIS的透析服务测量方法中的差距，并为未来的研究提出了建议。2016年5月，我们对PubMed、Embase、科学网、Scopus、Science Direct和IEEE Xplore中与GIS相关的现有证据进行了三步系统映射回顾，并在2017年10月通过两个独立的筛选过程对收集到的信息进行了更新。我们使用一种非正式的混合方法评分系统对研究质量进行了评估。在识别出的1119篇文献参考中，经过去除重复文献、研究筛选和应用纳入/排除标准后，确定了36篇用于最终回顾。根据所选研究的内容，确定了三个研究组，并确定了41个可能对透析服务产生影响的因素。这些研究主要涉及透析服务的潜在和/或空间方面。我们对证据的系统映射回顾表明，当前基于GIS的透析服务测量方法倾向于计算潜在的透析服务，而不是实际的透析服务。还注意到，列出的影响透析服务的因素主要是非空间因素，由此提出一个假设，即设计一个综合的透析服务指数可能会产生比目前所倡导的更好的透析服务得分。我们提出了一些主要和次要的研究建议，并提供了一份建议清单。
