Spatial Accessibility to ICU Beds and Ventilators in Illinois

Authors: Jeon-Young Kang, Alexander Michels, Fangzheng Lyu, Shaohua Wang, Nelson Agbodo, Vincent L. Freeman & Shaowen Wang

Paper: https://doi.org/10.1186/s12942-020-00229-x

Abstract: This aims to measure spatial access for people to hospitals in Illinois. The spatial accessibiilty is measured by the use of an enhanced two-step floating catchment area (E2FCA) method (Luo & Qi, 2009), which is an outcome of interactions between demands (i.e, # of potential patients; people) and supply (i.e., # of beds or physicians). The result is a map of spatial accessibility to hospital beds. It identifies which regions need more healthcare resources, such as the number of ICU beds and ventilators. This notebook serves as a guideline of which areas need more beds in the fight against COVID-19.

What's Inside

A quick explanation of the components:

  • COVID-19Acc.ipynb is a notebook for calculating spatial accessibility and COVID-19Acc.html is an export of the notebook as HTML.
  • Data contains all of the data necessary for calculations:
    • Chicago_Network.graphml/Illinois_Network.graphml are GraphML files of the OSMNX street networks for Chicago and Illinois respectively.
    • GridFile/ has hexagonal gridfiles for Chicago and Illinois
    • HospitalData/ has shapefiles for the hospitals in Chicago and Illinois
    • IL_zip_covid19/COVIDZip.json has JSON file which contains COVID cases by zip code from IDPH
    • PopData/ contains population data for Chicago and Illinois by census tract and zip code.
    • Result/ is where we write out the results of the spatial accessibility measures
    • SVI/contains data about the Social Vulnerability Index (SVI)
  • img/ contains some images and HTML maps of the hospitals (the notebook generates the maps)
  • README.md is the document you're currently reading!
  • requirements.txt is a list of Python packages necessary to use the notebook (besides Jupyter/IPython). You can install the packages with python3 -m pip install -r requirements.txt
