Bloodstream Infection Multidrug-resistant Gram-negative Bacteria

Antimicrobial resistance (AMR) is a major threat to public health and the well-being of humans, with high mortality rates of infections caused by MDR GNB. Sub-Saharan Africa (SSA) suffers from a high burden of AMR, but access to adequate microbiological diagnostics for pathogen identification and resistance testing as well as to novel antibiotics that are effective against MDR GNB are scarce. Studies from high-income countries show improved survival of patients with such infections, if novel antibiotics against these pathogens are employed in a targeted manner. However, data from low- and middle-income countries (LMICs) is limited. The purpose of this study is to obtain an accurate picture of the epidemiology of MDR GNB in hospitals in Côte d'Ivoire, Guinea-Bissau and Nigeria, followed by the development and implementation of an evidence-based AMS algorithm, which is coupled to access to antibiotics (i.e. meropenem, ceftazidime-avibactam, cefiderocol and ceftazidime-avibactam + aztreonam) with proven activity against MDR GNB. Taken together, the overall goal is to improve the management of severe infections due to MDR GNB in SSA.
