Background and objective
The prevalence of COPD stage IV has been reported to 0.1-0.2%. Little is known about the survival in COPD stage IV. The study aim was to estimate the survival of patients with COPD stage IV .
A cross-sectional point-prevalence study was conducted 2005 to identify and describe all patients with physician-diagnosed COPD stage IV in the city of Östersund, Sweden (Stenfors Chest 2006). These 70 patients are monitored in a prospective closed cohort study. Their emergency and elective hospital visits are registered. The subjects are invited to an yearly out-patient check-up. The time point subjects were diagnosed with stage IV-disease is identified through retrospective analysis of medical records. Medical records and death certificates are used to identify date and place of death.
The cohort consist of 41 females and 29 males. Mean age at diagnosis of stage IV-disease was 67.6 (SD 10.7) years. The cohort had a median survival time of 8.2 years and a 5-year survival of 69% after diagnosis of COPD stage IV.
Patients diagnosed with COPD stage IV have an long median survival time. The cohort has a complete follow-up, but is biased towards patients with hospital-based diagnosis of COPD stage IV and subjects were identified through hospital-based medical records. The attention patients receive taking part in a prospective study may lead to better survival.
