Impact of Systemic Manifestations/Comorbidities on Clinical State, Prognosis, Utilisation of Health Care Resources in Patients With COPD (COSYCONET)

Impact of Systemic Manifestations/Comorbidities on Clinical State, Prognosis and Utilisation of Health Care Resources in Patients With COPD

The purpose of this study is to determine the prevalence and severity of extrapulmonary disorders and to quantify the impact of extrapulmonary organ manifestations on morbidity and mortality of COPD patients.

Furthermore the investigators evaluate the relationship between systemic inflammation and organ involvement.

Study Overview

• Status: Completed
• Conditions: Chronic Obstructive Pulmonary Disease (COPD)

Detailed Description

Chronic diseases and comorbidities have an increasing impact on individual life and health care use, as exemplified in chronic obstructive pulmonary disease (COPD). Currently, independent, comprehensive databases allowing for an integrated view are lacking. The study will for the first time establish a large, comprehensive longitudinal database covering a broad panel of comorbidities an markers of systemic alterations. These data will be of unique value in revealing specific phenotypes of COPD via patterns and risk profiles of comorbidities, enabling a more precise diagnosis and targeting of therapy, and an efficient allocation of resources.

Participation Criteria

Eligibility Criteria

• Ages Eligible for Study: 40 years and older (Adult, Older Adult)

Study Population

Since the original recruitment strategy was not as successful as expected,the mode of recruitment was extended to other physicians, patients' groups and organisations and advertising to local media. The recruitment is supported by professional measures of communication organized by the coordinating centre Marburg.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change from baseline in BODE-Score at 18 months	The BODE-Score comprises BMI, airway obstruction, dyspnea and exercise capacity and is a good predictor for death in COPD patients. Progression is defined as a change in BODE-score by >=1 point over the observation period.	at initial visite, after 18, 36, 54, 72, 90 and 108 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
COPD related mortality	The rate of mortality was elevated after 6, 18, 36, 54, 72, 90 and 108 months	after 18 months
COPD related hospitalization	The rate of hospitalizations was elevated in every visit.	after 18, 36, 54, 72, 90 and 108 months
