Development and validation of a model to predict the 10-year risk of general practitioner-recorded COPD.

ABSTRACT:

Background

There is increasing interest in the earlier detection of, and intervention in, patients at highest risk of developing chronic obstructive pulmonary disease (COPD).

Aims

The objective of this research was to develop and validate a risk prediction model for general practitioner (GP)-recorded diagnosis of COPD.

Methods

We used data from 239 Scottish GP practices; two-thirds were randomly allocated to a derivation cohort and the other third to a validation cohort. We included patients aged 35-74 years at the cohort entry date, and excluded patients with a recorded diagnosis of COPD prior to the entry date and with missing data on smoking status.

Results

There were 480,903 patients in the derivation cohort and 247,755 in the validation cohort. The inciden
