Effect of ethnicity and migration on risk of bacteremia, multi-drug resistance and mortality after bacteremia: a register-based cohort study

The aim of the project is to study the association between bacteremia (bloodstream infection) and ethnicity/migrant status.

 The project sets out to investigate the following three questions:

  1. What is the effect of ethnic background and migrant status on incidence of bacteremia, including variations in causal infectious agents?
  2. What is the effect of ethnic background and migrant status on the incidence of multi-drug resistant organisms among patients with bacteremia?
  3. What is the effect of ethnic origin and migrant status on all-cause mortality after bacteremia?

We wish to obtain a better understanding of disparities in bacteremia related to ethnicity and migrant status. We expect to identify high risk groups and thereby help direct future prevention and treatment of migrants and finally help reduce inequalities in the incidence of and mortality from bacteremia among migrants compared to Danish-born. The study will be carried out by MD Rikke Thoft Nielsen under supervision of Marie Nørredam, Danish Research Center for Migration, Ethnicity and Health, University of Copenhagen; Christian Østergaard Andersen, Department of Clinical Microbiology, Hvidovre Hospital; Henrik Schønheyder, Department of Clinical Microbiology, Aalborg University Hospital. The project started March 1st 2017.
