Background Thoracic surgery in Germany is primarily provided in non-university centres with a clinical focus and less at university hospitals. The extent to which scientific activity can be achieved within these different structures is investigated on the basis of publication output. Material and Methods A PubMed analysis was carried out for selected authors (leader in thoracic surgery in Germany) between Jan 2012 to Dec 2021. University hospitals, DKG-certified lung cancer centres (DKG: German Cancer Society) and DGT-certified thoracic centres (DGT: German Society for Thoracic Surgery) were included. Results An analysis of n = 54 non-university centres (DKG certificate n = 50 and/or DGT certificate n = 22) and n = 36 university hospitals (n = 9 autonomous clinic/department) was performed. A total of n = 2414 publications were identified, with original papers (n = 1776; 74%) and publications focussing on thoracic surgery (n = 1501; 62%) being found most frequently. The publication performance of the non-university centres was n = 599 publications (11/centre) and thus significantly lower than that of the university hospitals (n = 902; 25/clinic; p <= 0.001). Significantly higher publication output was confirmed for autonomous (n = 560; 62/clinic) compared to non-autonomous university thoracic surgery (n = 342; 13/clinic; p = 0.003). A 10-year trend was recorded, with almost doubling of publication output from n = 105 (university: n = 63) to n = 203 (university: n = 124) publications/year. The cumulative impact factors (IF) resulted in 2845 IF (52.7 IF/clinic) for non-university centres, 6361 IF (235.6 IF/clinic) for non-autonomous and 2931 IF (325.7 IF/clinic) for autonomous university thoracic surgery. Conclusion Scientific activities have increased in non-university centres, but above all in university thoracic surgery. These positive developments are in acute danger due to the upcoming political changes (Hospital Structure Act, minimum volumes). Structural changes such as independent university thoracic surgery or cooperation models with non-university centres could offer solutions.
