NPJ Prim Care Respir Med. 2014 Jul 3;24:14015. doi: 10.1038/npjpcrm.2014.15.

Abstract

Background: Since the introduction of the Quality and Outcomes framework, there has been some evidence of improvement in the management of chronic obstructive pulmonary disease (COPD) patients in the United Kingdom through increasing rates of smoking cessation advice and immunisations against influenza. However, it is unknown whether disease-specific management criteria, disease outcomes and diagnosis have improved.

Aims: To describe changes in the management and outcomes of patients with COPD in UK general practice between 2000 and 2009.

Methods: The study was done on a retrospective cohort using data from The Health Improvement Network UK primary care database. We calculated age at diagnosis of COPD and death, total number of short-term oral corticosteroid courses and consultations, and proportion of patients with very severe COPD and on triple inhaled therapy for each year between 2000 and 2009.

Results: We identified 92,576 patients with COPD. The mean age at COPD diagnosis decreased from 68.1 years in 2000 to 66.7 years in 2009. The mean age at death increased from 78.2 years in 2000 to 78.8 years in 2009. The number of prescribed courses of oral corticosteroids increased from 0.6 in 2000 to 0.8 in 2009. The number of consultations increased from 9.4 in 2004 to 11.3 in 2009. The risk of having very severe COPD decreased from 9.4% in 2004 to 6.8% in 2009. The likelihood of patients with very severe COPD receiving triple therapy increased from 25% in 2004 to 59% in 2009.

Conclusions: The trends suggest that management and outcomes observed in patients with COPD may have improved since the year 2000.
