Scientific title	PRedicting Outcome using systemic Markers In Severe Exacerbations of Chronic Obstructive Pulmonary Disease (COPD): the PROMISE-COPD cohort study
Study acronym	PROMISE-COPD
Study hypothesis	Circulating biomarkers might be able to predict exacerbations during the stable state of the disease and the clinical outcome of the exacerbations in patients with chronic obstructive pulmonary disease (COPD). Thus, we aim to: 1. Describe the four-week course of clinical, laboratorial, and lung function parameters during exacerbations of COPD as compared to the stable state of the disease 2. Explore predictors that might identify recurrence and poor outcome in the stable state and during exacerbations 3. Analyse the potential of circulating biomarkers for the diagnosis and prognosis of COPD in the stable state and during exacerbations, including a correlation with the number of hospitalisations and death of any cause 4. Assess whether easily to determine circulating biomarkers are capable to replace the widely accepted BODE (body mass index, airflow obstruction, dyspnea, and exercise capacity) index as predictor of long term prognosis in COPD 5. Analyse the impact of viral and bacterial infections as well as pulmonary embolism on in-hospital and long-term clinical outcomes
Ethics approval(s)	Ethics Committee of Basel (Ethikkommission Beider Basel) (Switzerland), 24/09/2007, ref: EKBB 295/07
Condition	Chronic obstructive pulmonary disease (COPD)
Intervention	COPD will be diagnosed according to the GOLD guidelines (forced expiratory volume in one second [FEV1]/forced vital capacity [FVC] ratio below 70% and an absolute reduction of FEV1 below 80% of the predicted value). Acute exacerbation of COPD will be defined as "an event in the natural course of the disease characterised by a change in the patient's baseline dyspnea, cough, and/or sputum that is beyond normal day-to-day variations, is acute in onset, and may warrant a change in regular medication in a patient with underlying COPD".
Intervention type	Other
Primary outcome measure	Clinical end-points include the following (duration of follow-up: two years): 1. Number of exacerbations, including exacerbations requiring hospitalisation and exacerbations managed by the primary care physicians 2. Number of deaths of any cause 3. Number of respiratory-related deaths 4. Time to next exacerbation, time to next exacerbation requiring hospitalisation and time to death 5. Duration of hospitalisation 6. Admission and length of stay in intensive care unit 7. Need for intubation or non-invasive ventilation 8. Need for oral steroids and antibiotics 9. Lung function and 6-minute walk test changes
Secondary outcome measures	1. Quality of life assessed by Saint Georges Respiratory Questionnaire and the 36-item Short Form Health Survey (SF-36) at every scheduled visits during the follow-up phase (every 6 months) and 4 weeks after an exacerbation 2. Dyspnea and respiratory symptoms as assessed by the Modified Medical Research Council (MMRC) scale and Lower Respiratory Tract Illness - Visual Analogue Scale (LRTI-VAS) at every scheduled visits during the follow-up phase (every 6 months) and 4 weeks after an exacerbation Added 27/10/2010: 3. Measurement of daily physicial activity as assessed by a triaxial accelerometer at stable phase of the disease and exacerbation
