Abstract

Objectives: Fiji could be the first country to eliminate tuberculosis. To inform this strategy, we aimed to identify how many GeneXpert® machines are required to enable over 90% of Fijians to be within one-hour easy access.

Methods: We used Geographic Information System (Quantum GIS; QGIS), OpenStreetMap and population data (Kontur) to map possible facilities in relation to QGIS generated 60-min drive-time isochrones, with correction for missing road data. For outer islands, we calculated a distance to nearest hub operation.

Results: The solution comprised 24 GeneXpert® machines, allocating 7 GeneXpert® to Viti Levu, 6 GeneXpert® to Vanua Levu and 11 to other islands. This resulted in 827,810 people, 93.6% of Fiji's population, being within 1 h of a machine. Twenty-one thousand four hundred seventy-nine people on outer islands were an average of 43 km by water from the nearest facility.

Conclusions: We conclude that over 90% of Fijians could be within an hour of a GeneXpert® machine with placement of 24 machines.

在斐济采用以消除结核病为重点的地理空间方法，优化基因Xpert诊断仪的使用。

目标：斐济有可能成为第一个消灭结核病的国家。为了为这一战略提供信息，我们旨在确定需要多少台 GeneXpert® 设备才能让 90% 以上的斐济人在一小时内方便地获得服务：我们使用地理信息系统（Quantum GIS；QGIS）、OpenStreetMap 和人口数据（Kontur）绘制了与 QGIS 生成的 60 分钟车程等时线相关的可能设施地图，并对缺失的道路数据进行了校正。对于外岛，我们计算了到最近的枢纽运行的距离：解决方案包括 24 台 GeneXpert®，其中 7 台分配给维提岛，6 台分配给瓦努阿图，11 台分配给其他岛屿。这使得 827 810 人（占斐济总人口的 93.6%）在 1 小时内就能用上基因检测仪。外岛的 2.1479 万人距离最近的设施平均有 43 公里的水路距离：我们的结论是，如果安装 24 台 GeneXpert® 设备，90% 以上的斐济人可在 1 小时内到达设备所在地。
