Description
Codes indicating a diagnosis of a lower respiratory tract infection excluding pneumonia
Methodology
The LRTI codelist was developed in line with Rothnie et al (see reference list) in order to identify COPD patients who were experiencing exacerbations of COPD. It is linked with the corresponding COPD exacerbation list.
This codelist was derived by the following method:
- Read 2 Codelist provided by LSHTM.
- Codes from Quality Outcome Framework (QOF) were examined and there were no relevant codes for LRTI
- Codes from SNOMED were taken by searching for relevant codes
These 3 lists were mapped into CTV3 by TPP to create one list. This list was examined by 2 people and the following logic applied (see github issue for more detail): - Pneumonia codes were removed as per Rothnie protocol
After discussion, bronchiolitis and virus detected codes were kept in to keep in line with Rothnie protocol.

Codelists are developed by a broad community of users for individual study purposes, which may or may not meet the needs of other studies. They should not be thought of as universal definitions of a particular condition.
We don't offer any guarantees about what they do or don't identify. Users should carefully check that any codelist meets their needs, and seek clinical input where appropriate.
