A randomized controlled trial is conducted to test the hypothesis described above. Based on the independent clinical interpretation of the PatientProfileChart (see Peters et al., 2009) by three professionals, patients are assigned to one of the following groups: 1. Patients with no clinically relevant problems in health status (group I), and 2. Patients with clinically relevant problems in health status (group II/III). Patients with clinically relevant problems in health status are randomized to a control group (group II: usual care as delivered by the outpatient clinic) and the experimental group (group III: intervention conducted by a pulmonary nurse, directed at increasing awareness of problems in health status, increasing motivation to engage in additional treatment, and improving health status).
