There is scarce information about the allocation of health resources in Syria. Pre-existing inequalities were further intensified after the 2011 conflict which displaced over 50% of the population. This study provides an analysis of health inequalities in Syria focusing on spatial access to public hospitals and employs data from 2010, just prior to the outbreak of conflict. Establishing a preconflict snapshot of the health system could serve as a helpful baseline assessment for future studies to measure the impact of the conflict on the health system. Such information could also offer systematic data to guide postconflict reconstruction efforts.
We compared two methods to quantify the inpatient bed access: provider to population ratio (PPR) and two-step floating catchment area (2SFCA) method. We compared PPR calculated at the governorate level with population weighted 2SFCA score calculated at a resolution of 2 km by 2 km. We then aggregated at the governorate level, tested multiple catchment sizes and calculated Gini coefficient for each governorate.
We found high inequality in access to public hospitals across and within governorates, especially in the north and eastern regions, where all governorates ranked in the lowest two quintiles using both PPR and 2SFCA. Relatively small governorates in the west and the south had higher spatial access and less inequality. Testing variability in catchment size showed that even at 125 km catchment, 65% of the country had accessibility below national average.
Methodologically, the use of 2SFCA provided more nuanced insights about hospital bed allocation than PPR. 2SFCA was able to account for the cross-boundary effect and road network quality. Realistic representation of health accessibility is possible in data-scarce settings such as Syria and could be adapted to assess health access inequalities in conflict and postconflict settings.
关于叙利亚卫生资源配置的信息很少。2011 年冲突爆发后,超过 50%的人口流离失所,使原有的不平等现象进一步加剧。本研究聚焦于叙利亚的卫生不平等问题,特别是公共医院的空间可达性,并利用 2010 年冲突爆发前的数据进行分析。在冲突前建立卫生系统的现状快照,可以作为未来研究衡量冲突对卫生系统影响的有用基线评估。此类信息还可以为冲突后重建工作提供系统数据。
我们比较了两种方法来量化住院床位的可及性:服务提供者与人口的比例(PPR)和两步浮动集水区(2SFCA)方法。我们比较了在省一级计算的 PPR 与以 2 公里×2 公里分辨率计算的人口加权 2SFCA 得分。然后,我们在省一级进行汇总,测试了多个集水区的大小,并为每个省计算了基尼系数。
我们发现,各省内和省内之间的公共医院可达性存在很大差异,特别是在北部和东部地区,无论使用 PPR 还是 2SFCA,所有省份都排在最低的两个五分位数。西部和南部的相对较小的省份拥有更高的空间可达性和更少的不平等。测试集水区大小的变异性表明,即使在 125 公里的集水区内,仍有 65%的地区的可达性低于全国平均水平。
从方法论上讲,使用 2SFCA 比 PPR 提供了更细致的医院床位分配见解。2SFCA 能够考虑到跨界效应和道路网络质量。在数据匮乏的环境中,如叙利亚,可以实现对卫生可达性的真实表示,并可以适应评估冲突中和冲突后的卫生可达性不平等。
