Bewijs uit registratiestudies voor atopisch eczeem

There is a lack of evidence regarding many aspects of therapies that are available for atopic eczema. Treatment variation exists between dermatologists and between countries. Good comparative research and research on different subgroups of patients and the long-term (cost)effectiveness and safety of systemic therapy and phototherapy is lacking. It will not be feasible to perform (long-term) RCTs to investigate all comparisons between treatments and subgroups of patients. In registries data are collected from patients in daily practice. Harmonization of data collection, both on a national and international level, is important to investigate large numbers of patients. More new expensive treatments will become available for atopic eczema in the future. It is important to collect evidence in order to improve quality of care.
