Study population: Eligible subjects are all COPD patients, found in medical records at the participating swedish primary care clinics. Primarily patients with diagnosis code J44 (ICD-10) stated in the medical record will be investigated. Patient data from the period 1 January 1999 - 31 December 2009 will be included in the observation.

Brief summary: The aim of this study is to describe COPD health care and to assess demographics, concurrent diseases and mortality and the use of pharmaceuticals for a chronic obstructive pulmonary disease (COPD) population in real life in primary care during the last ten years.


Eligibility criteria: Inclusion Criteria:

* COPD diagnosis according to medical records.
* Use of drugs prescribed for obstructive lung diseases
