Abstract

INTRODUCTION

One of the major challenges in developing countries is the inappropriate spatial distribution of medical laboratory centers (MLCs) which can lead to injustice in access to health services. This study aimed to investigate the accessibility to and site suitability of MLCs in Kermanshah Metropolis by GIS.

MATERIALS AND METHODS

In this cross-sectional study, data were collected from the Iran Statistical Center and Deputy of Treatment of Kermanshah University of Medical Sciences. We used Arc/GIS 10.6 software, AHP technique, and network analysis tools to determine the access status of Kermanshah citizens to MLCs in 2019 and site selection for MLCs. The layers used in this study included population density, city development trends, compatible and incompatible land uses, pathways, land slope, river area, and access radius.

RESULTS

About 70% of households had inappropriate access to all MLCs in walking scenario. This ratio was 31.26% for 5 min, 9.58% for 10 min, and 6.09% for 15 min driving. Comparisons between public and private MLCs showed that in walking scenario, 88% of households had improper access to public and 80% to private MLCs. Based on 5 and 10 min of driving, 57 and 19% of households had inappropriate access to public MLCs, and 45 and 17% to private MLCs, respectively. Also, with 15 min of driving, 8% of households had improper access to public and 18% to private MLCs. Findings showed that scores provided for population density criteria were (0.298), distance from existing laboratories (0.213), proximity to pathways (0.175), consistent land use (0.129), city development trend (0.087), distance from riverfront (0.053), distance from incompatible land uses (0.015), and land slope (0.03). The final model was obtained by overlaying the layers. The model showed a 9-degree range from very bad to very good in Kermanshah city for the construction of laboratory centers (CR<0.01).

CONCLUSION

The site selection model showed that the location of the proposed centers can be in the north and outskirts of the city to facilitate citizens' access to the MLCs. These results emphasize the justice in the spatial distribution of MLCs for the benefit of deprived populations as a global value.

摘要

简介

发展中国家面临的主要挑战之一是医学检验中心（MLC）的空间分布不当，这可能导致医疗服务获取方面的不公平。本研究旨在通过 GIS 调查克尔曼沙赫大都市 MLC 的可达性和选址适宜性。

材料与方法

在这项横断面研究中，数据来自伊朗统计中心和克尔曼沙阿医科大学治疗部门。我们使用 Arc/GIS 10.6 软件、层次分析法（AHP）技术和网络分析工具，确定 2019 年克尔曼沙赫市民前往 MLC 的可达性状况和 MLC 的选址。本研究使用的图层包括人口密度、城市发展趋势、兼容和不兼容土地利用、路径、土地坡度、河流区域和可达半径。

结果

在步行情景下，约 70%的家庭前往所有 MLC 的可达性不适当。5 分钟、10 分钟和 15 分钟驾驶时，这一比例分别为 31.26%、9.58%和 6.09%。公共和私人 MLC 之间的比较表明，在步行情景下，88%的家庭前往公共 MLC 的可达性不适当，80%的家庭前往私人 MLC 的可达性不适当。基于 5 分钟和 10 分钟的驾驶，57%和 19%的家庭前往公共 MLC 的可达性不适当，45%和 17%的家庭前往私人 MLC 的可达性不适当。此外，在 15 分钟的驾驶时间内，8%的家庭前往公共 MLC 的可达性不适当，18%的家庭前往私人 MLC 的可达性不适当。研究结果表明，人口密度标准提供的分数为（0.298），与现有实验室的距离（0.213），与路径的接近程度（0.175），土地利用一致性（0.129），城市发展趋势（0.087），与河滨的距离（0.053），与不兼容土地利用的距离（0.015），以及土地坡度（0.03）。最终模型是通过叠加各图层得到的。模型显示，克尔曼沙赫市在建设实验室中心方面的等级范围为 9 级，从极差到极好（CR<0.01）。
