Reproduction and Reanalysis of Kang et al 2020 Spatial Accessibility of COVID-19 Health Care Resources

This study is a replication of:

Kang, J. Y., A. Michels, F. Lyu, Shaohua Wang, N. Agbodo, V. L. Freeman, and Shaowen Wang. 2020. Rapidly measuring spatial accessibility of COVID-19 healthcare resources: a case study of Illinois, USA. International Journal of Health Geographics 19 (1):1–17. DOI:10.1186/s12942-020-00229-x.

Abstract

The original paper is an implementation of the enhanced two-step floating catchment area (E2FCA) method of spatial accessibility measurement in health geography, applied to accessibility of intensive care unit beds and ventilators in the state of Illinois for vulnerable people aged 50 or over or diagnosed with COVID-19. The study is significant in its use of parallel processing and cyberinfrastructure, implemented on the CyberGISX system, and the study provides reproducibility and transparency for the COVID-19 spatial health services accessibility dashboard, Where COVID-19.

Spatial Accessibility to ICU Beds and Ventilators in Illinois

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:

• 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)
