Summary

Aim

We aimed to estimate the societal treatment-related costs of COPD in hospital- and population-based subjects with spirometry defined COPD, relative to a control group.

Methods

81 COPD cases and 132 controls without COPD were randomly recruited from a general population, as were 205 COPD patients from a hospital register. All participants were ever-smokers of at least 40 years of age, followed for 12 months. Data on comorbid conditions and spirometry were collected at baseline. Standardized telephone interviews every third month gave information on use of healthcare services and exacerbations of respiratory symptoms.

Results

The increased (excessive) median annual costs per case having stage II, stage III and stage IV COPD were € (95% CI) 400 (105–695), 1918 (1268–2569) and 1870 (1031–2709), respectively, compared to the population-based controls. Costs increased with €81 (95% CI 50–112) per exacerbation of respiratory symptoms and €461 (95% CI 354–567) per comorbid condition. Excessive costs for hospital COPD patients were threefold that of the population-based COPD cases.

Conclusion

The excessive treatment-related cost of COPD stage II+ in ever-smokers of at least 40 years was estimated to €105 million for Norway. Comorbidity was a dominant predictor of excessive cost in COPD.
