# Mappings

This folder contains a range of mappings used within the processing stages of model E:
- `inhaler_mapping.json`: Inhaler mappings for any Chapter 3 BNF code inhaler prescriptions present in the SafeHaven prescribing dataset. Information on NHS inhaler types, found [here](https://www.coch.nhs.uk/media/172781/3-respiratory-system.pdf), was used to create the mapping.
- `test_mapping.json`: A mapping created for any of the top 20 most frequently occurring lab tests, plus any lab tests found relevant for indicating COPD severity in Model A. This mapping creates a common name for a specific test and lists any related names the test may appear under within the SCI Store dataset.
- `Comorbidity feature review for models & clin summary update v2 May 2021.xlsx`: A mapping between diagnosis names found in SMR01 and their associated comorbidities (taken from Model A).
- `diag_copd_resp_desc.json`: DIAGDesc for COPD and respiratory admissions
