[Implementation of the German Guideline for the Prevention, Diagnosis, Treatment, and Follow-up of Lung Cancer in the Federal State of Berlin].

BACKGROUND
In February 2010, the German guideline for the Prevention, Diagnosis and Treatment of Lung Cancer has been published. For the first time in Germany, the implementation of relevant guideline recommendations has been assessed in the federal state of Berlin.


METHODS
Based on the quality indicators of the guideline, a questionnaire was designed which aimed at the application of selected diagnostic and therapeutic concepts. This questionnaire was sent out to all outpatient and inpatient units in the federal state of Berlin being presumably involved in lung cancer care.


RESULTS
Overall response rate was good (39.8 %), especially from the addressed inpatient units. Inpatient pneumology units showed the highest application rates of guideline recommendations, followed by oncology units.


CONCLUSIONS
Taking the methodologically reduced significance of a survey design into account, this study determined a negative trend of decreasing guideline implementation in units with a lesser grade of specialisation in terms of lung cancer care.
