中华健康快车白内障患者人工晶状体度数的地域性分布及资源配置

Regional distribution and resource allocation of intraocular lens diopter in cataracts on Lifeline Express

目的分析中华健康快车白内障人群中人工晶状体度数分布的总体情况及地域性特点,探讨更好的医疗资源配置方案。方法搜集整理2014年至2016年中华健康快车项目在全国七大行政区域实施免费白内障手术的27 663例患者资料,统计所有患者的人工晶状体度数,掌握白内障人群中人工晶状体度数总体分布情况,并分析不同行政区域间人工晶状体度数分布的地域性差异。结果在27 663例白内障患者中,人工晶状体度数分布呈现偏态分布,峰值出现在21~<22D,出现频率较大的度数主要集中在19~<24D,占总量的72.48%。东北地区、华北地区、华中地区、华东地区人工晶状体度数峰值均出现在22~<23D,且整体波形向大度数方向偏移;西北地区、西南地区、华南地区人工晶状体度数峰值出现在21~<22D,且整体波形呈现向小度数方向偏移趋势。IOL<10D的出现频率在西北地区、东北地区、华北地区和华东地区明显较多,IOL≥25D的出现频率在华中地区、东北地区、华东地区、华北地区明显较多。结论各大行政区域内白内障患者人工晶状体度数呈现偏态分布,不同地区之间有细微差异。本研究结果可以为各地大规模白内障手术资源配备提供依据。

Objective To investigate the better medical resource allocation scheme by analyzing the overall situation and regional characteristics of intraocular lens diopter in cataract patients on Lifeline Express.Methods The total of 27 663 patients data from seven administrative regions of China on cataract surgery in China Lifeline Express from 2014 to 2016 were collected.All diopter values of IOL were recorded to grasp the overall distribution of IOL diopter in cataract patients,and the distributive difference among administrative regions was analyzed.Results The distribution of IOL diopter in 27 663 cataract patients presented a skewed trend,with peak value in 21-〈22 D.The greater frequency of IOL diopter was mainly concentrated in 19-〈24 D,accounting for 72.48% of the total.The IOL diopter peak was present in 22-〈23 D in Northeast China,North China,Central China,East China,and the overall waveform offset to a large degree direction.The IOL diopter peak was present in 21-〈22 D in Northwest,Southwest,South China,and the overall waveform showed the trend of small degree direction.The occurrence frequency of IOL with diopter〈10 D was significantly more obvious in Northwest,Northeast China,North China and East China.At the same time,the occurrence frequency of IOL with diopter ≥25 D was significantly more obvious in Central China,Northeast China,East China,North China.Conclusion The IOL diopter values of cataract patients in different administrative regions present a skewed distribution and there are subtle differences between different regions.The results can provide the basis for resource allocation for large scale cataract surgery in each area.
