Description

Identifies COPD exacerbation hospital admissions.

Methodology

This codelist is part of a validated algorithm to identify chronic obstructive pulmonary disease (COPD) exacerbation (see reference). COPD exacerbation in secondary care is identified if any of the following criteria are met: 1) COPD exacerbation specific code (this codelist) in any position. 2) COPD diagnosis code (COPD secondary care codelist) in first position. 3) Lower respiratory tract infection code (lower respiratory tract infection - secondary care codelist) in first position and a COPD diagnosis code in any position.

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.
