Description

Identifies COPD 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 (COPD exacerbation codelist) in any position. 2) COPD diagnosis code (this 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.
