title: [Analysis of the publication spectrum of 4 German-language medical specialty periodicals "Der Chirurg", "Der Unfallchirurg", "Langenbecks Archiv für Chirurgie" and "Medizinische Klinik"].
abstract: All 1994 publications of four leading journals in surgery, orthopedics and internal medicine in Germany (Der Chirurg, Der Unfallchirurg, Langenbecks Archiv für Chirurgie, Medizinische Klinik) were reviewed by means of a structured analysis. The type of article, authorship, number of references, geographical location, quality, and main conclusion (positive; neutral; negative) of each article were documented. The journals focused on clinical studies (32.2-59.6%), case reports (11.0-26.1%) and reviews (6.4-40.9%). Articles about surgical techniques were mainly found in Der Chirurg (16.9%), experimental studies in Der Unfallchirurg (14.7%) and Langenbecks Archiv für Chirurgie (25.7%). Most articles were written by university clinic personnel (62.6-81.4%). In 11.0-22.6% of all articles, the head of a clinic was the first author and the co-author in 36.5-58.7%. Women were found to be first author in 4% in surgery, and in 10.4% in internal medicine. Of a total of 495 publications, 53.9% were written in Northrhine-Westphalia, Bavaria or Baden-Württemberg and only 1.6% in the five new federal states. Of all articles 16.4% were by foreign authors, with 10.5% originating from German-speaking countries. The portion of controlled randomized trials ranged between 4.9% (Der Unfallchirurg) and 11.3% (Der Chirurg) of all published studies. Studies and case reports with negative results were found to be more evident in Der Chirurg and Langenbecks Archiv für Chirurgie (ca. 20%) as compared to Der Unfallchirurg and Medizinische Klinik (ca. 6%). All journals provided good general information about the actual developments in a variety of topics to the reader. However, some improvement concerning international contributions, participation of the new federal states, and the quality of studies is recommended.
