Nationwide quality improvement in lung cancer care: the role of the Danish Lung Cancer Group and Registry.

Introduction: To improve prognosis and quality of lung cancer care the Danish Lung Cancer Group has developed a strategy consisting of national clinical guidelines and a clinical quality and research database. The first edition of our guidelines was published in 1998 and our national lung cancer registry was opened for registrations in 2000. This article describes methods and results obtained by multidisciplinary collaboration and illustrates how quality of lung cancer care can be improved by establishing and monitoring result and process indicators.
