Real-world clinical data identifies gender-related profiles in chronic obstructive pulmonary disease.

摘要

This study aims to compare diagnostic and clinical outcomes of Chronic Obstructive Pulmonary Disease (COPD) from the gender perspective using retrospective health care data and patient reported outcomes in a real-world setting. An electronic database was constructed from complete medical records of 844 COPD patients who were recruited in Helsinki and Turku University Central Hospitals during the years 2005-07. The patients were identified from the hospital discharge registries by ICD10 code J44.8 in the age group of 18-75 years of age. The medical history was obtained from all healthcare providers who had treated these patients during the previous 5-10 years; the study intends to continue their follow-up annually for the next 10 years. Thirty-six percent (N = 266) of the participants were women. The COPD diagnosis had been made at the same age for both genders. Women, however, reported significantly less pack-years than men. Compared to the men, the women displayed less advanced airway obstruction, but more severe gas transfer impairment. Parenchymal damage when evaluated by diffusion capacity correlated significantly stronger with FEV(1) (% of predicted) in women than men. The BMI index of the women was lower than that of the men. Cardiovascular diseases, diabetes and alcoholism were significantly more common in men, but women suffered more psychiatric conditions, especially depression. This cohort showed several significant gender dependent differences in the clinical presentation that need to taken under consideration in the assessment of COPD progression and the disease management.
