Spatial distribution analysis of blood donors′ intended donation addresses based on ArcGIS
Journal Title: Chinese Journal of Blood Transfusion - Year 2022, Vol 35, Issue 12
Abstract
Objective To apply the spatial distribution analysis based on ArcGIS software, which has been applied widely in other fields, so as to analyze the intended locations for whole blood donation. Methods After a random stratified sampling was conducted among blood donors in the 17 donation sites during August 1st, 2021- July 30th, 2022, their intended blood donation locations were collected by an e-questionnaire. Addresses of donors′ intended donation locations were derived for GCJ-02 coordinates form and transformed by pandas module of Python to WGS84 coordinates, which further loaded to ArcGIS Arcmap module using Grouping Analysis for 17 median centers. The addresses of 17 blood donation sites in Guangzhou Blood Center were transformed to WGS84 coordinates and loaded to ArcGIS Arcmap module using the same methods for 3 ring buffer analysis. The criterion for judging whether the two were " matched" was whether the intended blood donation sites were covered by or adjacent to the 3 ring buffer zone of the existing blood donation sites. Results Of the 17 potential sites obtained from the spatial distribution analysis of 40 523 valid addresses of donors, 8 sites were covered or adjacent to the buffer of the existing donation sites, while the other 9 sites were far away from the existing donation sites. Conclusion By analyzing the spatial distribution of donors′ intended donation addresses, we can find out the service needs of donors for donating blood conveniently, which can provide basis for further blood donation service optimization.
