Exploring general practice research in Germany: a systematic review of dissertation topics from 1965–2023

Background: Since its academic inception in the 1960s, Germany’s general practice has seen numerous dissertations, many of which are housed in the ‘Archive of German language General Practice’ (ADAM). Aim: This study aims to provide the first comprehensive overview of dissertation topics from the discipline of general- and family medicine in Germany, establishing a foundation for advancing research. Method: We employed a systematic review approach, examining 801 dissertations from both ADAM and online sources. Each topic was identified, categorized, and finalized through consensus by two independent reviewers. Results: Our analysis encompassed 486 dissertations from ADAM, 176 from the German national library, and 139 from university libraries. A total of 167 unique research topics were identified. The predominant themes included medical education (n = 49), medication orders (n = 39), frequent consultation issues (n = 33), complementary medicine (n = 32), and screening measures (n = 29). The use of qualitative methods was constantly rising, from no qualitative methods used from 1965–1974, up to 22% of dissertations in recent years. Conclusion: The diversity of 167 research topics underscores the vastness and complexity of general practice in Germany. This structured overview is pivotal for facilitating focused and interconnected research endeavors in the field.
