BACKGROUND  The state of research in the field of abdominal ultrasonography has been deficient for years at German university hospitals. Neither research activity nor funding are appropriate given the actual clinical importance of this method. OBJECTIVE  In analogy to studies conducted in 1999 and 2009, this study aims to provide a survey into the state of research in the field of abdominal ultrasonography at German university hospitals. It focuses on the topics of research activity, research funding, publication rate and the development of structural conditions. METHODS  Chief gastroenterologists from Germany's 34 university hospitals were invited to respond to a postal survey asking about the aforementioned topics. We asked them to forward the survey in case somebody else was responsible for the respective tasks. The response rate was 79 %. RESULTS  The amount of hospitals doing research has roughly remained the same with 77 % compared to 74 % in 2009 and 80 % in 1999. On average, however, there are less research projects per department with 3.2 at the moment compared to 3.5 in 1999 and 3.6 in 2009, and research funding has continued to worsen. 75 % of the heads of departments state that they have not received any funding in addition to the usual budget. Funding by producers of ultrasound machines has also reached a low with 11 % compared to 45 % in 2009 and 31 % in 1999. Only public and university funding show a positive trend. The Deutsche Forschungsgemeinschaft (German Research Foundation) is currently not funding any research projects in the field of abdominal ultrasonography. 13 university hospitals provided information about their publication rate in 1999, 2009 and 2019. Whereas the rate had generally remained constant in the previous studies, the annual number of publications has continually increased in the current survey period. 75 % of the publications came from university hospitals that have established or are currently planning to establish interdisciplinary ultrasound centers. The previous studies also showed that more and more hospitals publish in English instead of German. This trend continues. During the survey period, 60 % of publications were both in English and German, 37 % in English and only 3 % exclusively in German. Most publications dealt with clinical and only a few technical or basic research questions. This was also the case in the previous studies. There have been less publications on the use of ultrasound contrast agents in the present survey period. There is also a decline in the number of systematic reviews. Similar to 2009, the impact factor of journals devoted to sonography is increasing and it is growing stronger than that of journals dedicated to radiology. However, only 29 % of the heads of departments agreed that ultrasonography was a field of research that improves your career prospects. CONCLUSIONS  The present study did not show a significant improvement of research activity in the field of abdominal ultrasonography. However, an increased publication rate indicates a trend towards high-performing research centers. Research funding remains deficient and has worsened in the past 20 years. The demands made by the previous studies for research funding appropriate to the importance of this clinical method remain.
