The attacks of 9-11 have been not only the cause of the deaths of thousands of people but have also had an enormous impact on the health of the survivors, the rescue workers, the fire fighters and many more people worldwide. This study aims to depict a representative global picture of the research output of 15 years after the attacks of 9-11 by analyzing the bibliometric data of the overall publications with particular focus on medical topics. This study subsequently deepens the scientometric approach of the overall terrorism research of Magnone in 2014, also published in Scientometrics. The USA has published the most by far, taking the absolute numbers into account. When evaluating citation or socio-economic ratios, Israel takes first place. The main collaborating partner of the USA is the UK, followed by Canada. The share of European countries is rising over time, linked with the terror attacks in European cities. There are only a few other countries involved. Prospective study approaches should be concentrated on international performances as a contribution in dealing with terrorism, its causes and its consequences. The improved access and involvement of other countries’ scientists in the research and publication processes by a greater network would be an important component in facing international terrorism.
