2005～2022年中国肿瘤医疗资源保障水平的空间差异及动态变化OA

Objective:To reveal the regional differences,spatial distribution and agglomeration of the level of cancer medical resource security in China from 2005 to 2022 from the perspective of permanent population,so as to provide scientif-ic basis for optimizing the spatial allocation of cancer medical resources.Methods:A cancer medical resource guarantee index based on permanent population was constructed,and the coefficient of variation,spatial autocorrelation and hotspot a-nalysis were used to explore the evolution characteristics of the spatial-temporal pattern of cancer medical resource guarantee level in China.Results:From 2005 to 2022,the number of oncology beds per 10,000 permanent residents in China in-creased from 0.55 to 1.93.Overall,the level of cancer medical resource provision showed an upward trend,while at the re-gional scale,the gap between the western region and other regions gradually widened.At the provincial scale,the coefficient of variation for the security level decreased from 0.62 to 0.37,with the decline occurring in two stable phases.Spatial auto-correlation results indicated a significant positive spatial correlation(P<0.01 for all years),with the Moran's I index showing a fluctuating upward trend.Hot spot analysis further revealed a gradual transitional spatial clustering pattern of Chi-na's cancer medical resource provision level,shifting progressively from hot spots in the eastern region to cold spots in the western region.Conclusion:Although the spatial disparity in the level of cancer medical resource provision in China has narrowed,the imbalance remains pronounced,particularly in the gap between regions at the regional level.It is suggested to strengthen regional linkage and establish a precise assistance system.The Internet,big data,and other technologies should be fully leveraged to ensure that remote high-quality medical resources meet actual healthcare needs.Additionally,a tumor monitoring network and referral system aligned with the permanent population distribution should be established.
