Prevalence of users of medication targeting obstructive lung disease, the reasons for prescriptions and the use of spirometry in Upernavik Health Center in the period from 2011-2016, a retrospective observational study as basis for future quality development

Chronic obstructive pulmonary disease (COPD) is a health problem globally. Smoking is a risk factor. In Greenland over 50% are smokers. Upernavik Healthcare Center serves the town of Upernavik and its 9 remote settlements. Many patients were treated with medications targeting obstructive pulmonary disease (ATC code R03). This retrospective observational study estimated the prevalence of users of R03 medication aged 50 years or above, investigated if spirometry was performed, the reason for prescription and smoking status. The study is based on review of data from the electronic medical journal. Permanent residents with prescriptions of R03 medication within a period of 5 years were included. Reasons for prescription and smoking status was registrated. The prevalence of users of R03 medications was 7,6%. 37,8% had a spirometry performed. The reason for prescribing varied from no reason to COPD-like. R03 medications were prescribed years before spirometry. 37,8% of the patients were smokers. Prevalence of users was comparable to other studies in Greenland. There was lack of spirometry and a discrepancy to guidelines. Patients had prescriptions of R03 medication years without a specific diagnosis. This warrant a new strategy for identification, increase of spirometry and treatment of patients with COPD to be developed.
