About

Description

Prevalent cases of neurodegenerative disease with an established diagnosis.

Methodology

Context

The codelist is for use in a neurodegenerative disease burden study (Bristol/ Edinburgh/ Cambridge); and captures prevalent cases with an established diagnosis. The codelists were developed for neurodegenerative diseases of interest: Dementia, Parkinson’s Disease, Parkinson’s-plus syndromes, Motor Neurone Disease. For the diseases of interest, we reviewed established codelists (e.g. QoF for SNOMED terms), and created any required codelists using diagnostic terms as search criteria. Shrimp browser and OpenCodeCounts were consulted for hierarchies and additional terms.

Inclusion/exclusion criteria

Clinical codes indicative of an established diagnosis were included.

Borderline cases

Infantile cases of striatonigral degeneration were included, as they belong to the broad term of genetic neurodegenerative disease. These have 0 usage.

Sensitivity vs specificity

The primary aim was specificity. We included codes representing a clinical diagnosis of the condition of interest, rather than codes based solely on symptoms or clinical features.

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.
