Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Time to event is the primary study outcome, for which an event is defined as a readmission to hospital due to an exacerbation or death. An exacerbation is defined using a modified version of the definition of Rodriguez-Roisin, as an event in the natural course of the disease defined as characterized by a change in the patient*s baseline dyspnoea, cough, and/or sputum that is beyond day-to-day variations, is acute in onset, and which is treated with an antibiotics course and/or prednisolon in patients with underlying COPD. | — |
