In many chronic diseases, including COPD, the patients' basic knowledge of the disorder has been shown to be relevant for the course of the disease. We studied which clinical and functional characteristics were related to this knowledge as well as the patients' satisfaction with their knowledge about COPD. Methods: The study population comprised 645 patients of GOLD grades 1-4 who participated in Visit 6 of the COSYCONET cohort (COPD and Systemic Consequences -Comorbidities Network). The assessments covered a broad panel of clinical and functional characteristics, including generic and disease-specific quality of life and the COPD Assessment Test (CAT). The study aim was addressed by two questions, referring to patients' knowledge of the meaning of FEV 1 and the overall satisfaction with their knowledge of COPD. Results: Knowledge of FEV 1 was higher in patients of higher spirometric GOLD grades or exacerbation risk, in males, with higher educational level, and after participation in a prior educational training on COPD. Patients with more detailed knowledge showed a higher satisfaction with their knowledge. Satisfaction was associated with higher generic quality of life and a lower CAT score. Furthermore, satisfaction was higher in patients with a treatment plan but lower in patients with cardiac comorbidities. It appeared that females with basic education, high burden from COPD and low quality of life had the greatest knowledge deficits. Discussion: The results suggest room for education programs adapted to the educational level of the participants. They also emphasize the major role of a disease management plan for the patients.
ZusammenfassungCOSYCONET 1 ist die derzeit einzige international konkurrenzfähige deutsche COPD-Kohorte. Die Rekrutierung begann Ende 2010 und endete im Dezember 2013. Sie resultierte in 2741 Patienten mit der Diagnose einer COPD, die in der Folge in regelmäßigen Visiten nachuntersucht wurden. Diese Visiten umfassten eine umfangreiche funktionelle und klinische Charakterisierung. Auf der Basis dieses hochwertigen Datensatzes war es möglich, eine Vielzahl klinischer Fragen zu beantworten. Diese reichten vom Verschreibungsverhalten über die genaue Analyse verschiedener Komorbiditäten, v.a. kardiovaskulärer Art, bis zu Biomarkern, radiologischen und gesundheitsökonomischen Analysen. Inzwischen wurden mehr als 60 Publikationen zu COSYCONET international veröffentlicht. Die nachstehende Arbeit liefert eine Übersicht über alle bislang erhaltenen Ergebnisse, mit einem besonderen Fokus darauf, deren wechselseitigen Zusammenhang sowie die möglichen praktischen Konsequenzen herauszuarbeiten. Ferner werden einige Informationen über die Folgestudie COSYCONET 2 gegeben.
