Are people with amigration background more likely to be classified in the MU group?; Methodology: Included were consecutive patients who visited three EDs in Berlin from July 2017 to July 2018. Using aquestionnaire, diseases, reasons for visiting the ED and socioeconomic factors were recorded. Comparisons between migrants (1st generation), their descendants (2nd generation) and nonmigrants were assessed using logistic regression.; Results: A total of 2339 patients were included in the evaluation (repeat rate 56%), of which 901 had amigration background. Young women (<30years), chronically ill, pregnant women, patients with severe complaints and people with (self-assessed) moderate and poor health quality as well as those without medical referral had agreater chance of multiple use of ED.; Conclusion: MU burden the already increasing patient volume of ED. However, they represent aheterogeneous group of patients, among whom people with amigration background are not common. Further research is warranted to better understand the factors that lead to frequent use and to develop effective strategies to address the complex health needs of MUs. © The Author(s) 2021. 25 4 252–259 252–259 Springer 2021 application/pdf 1
