This package contains a many-to-many mapping between local authority districts and NHS Acute Trusts in England; details of this mapping (including a summary of the methods and a quick-start guide) can be found in vignettes/mapping-summary.

This package also has functionality to download trust-level hospital admissions data, published weekly on the NHS COVID-19 Hospital Activity webpage. Data published on date YYYY-MM-DD can be downloaded using the function get_admissions(release_date = "YYYY-MM-DD"). This function can also be used to return estimated admissions by upper-tier and lower-tier local authorities. See the quick start below, the vignettes, and the package documentation for more.

Quick start

Load the package.

Download the latest admissions mapped to lower-tier local authority (LTLA) using the default mapping. Note: This data is updated weekly each Thursday and the mapping is a probabilistic estimate.

adm <- get_admissions("ltla")

Map the latest available estimates by LTLA using one of the built in package shapefiles.

map_admissions(adm, england_ltla_shape)

Plot the time series of estimated admissions in an example LTLA (here Derby).
