Supply-demand adjusted two-steps floating catchment area (SDA-2SFCA) model for measuring spatial access to health care

Social Science & Medicine, 2022
Spatial accessibility to health care plays a vital role in the evaluation of medical resource equality. A widely used method of spatial accessibility is the Two-Step Floating Catchment Area (2SFCA) method. However, the 2SFCA model (and its later variants) implicitly assumes that each doctor has the same attraction (unlimited resources) to care seekers ...

Variable catchment sizes for the two-step floating catchment area (2SFCA) method

Health & Place, 2012
Government efforts designed to help improve healthcare access rely on accurate measures of accessibility so that resources can be allocated to truly needy areas. In order to capture the interaction between physicians and populations, various access measures have been utilized, including the popular two-step floating catchment area (2SFCA) method ...

On the Modifiable Areal Unit Problem (MAUP) in healthcare accessibility measurement via the two-step floating catchment area (2SFCA) method

Health & Place
The widely used two-step floating catchment area (2SFCA) method for healthcare accessibility measurement might be biased due to the Modifiable Areal Unit Problem (MAUP), which remains unknown. This study calculates and compares healthcare accessibility via the Gaussian-based 2SFCA method at various spatial scales to identify the scale effects.
