The misuse and overuse of antimicrobials is a major driver of resistance. Among other factors associated with misuse/overuse is that clinicians often have insufficient information to prescribe the most appropriate course of treatment. For example, using clinical symptoms alone, it is difficult to distinguish bacterial infections - which can be treated with antibiotics - from viral infections - for which antibiotics should not be prescribed. Diagnostics are critical to such decision-making and the avoidance of misuse by providing information on the pathogen and its level of resistance, information on the host immune system, or the dosing required for individual patients.
At Imperial, interdisciplinary teams made up of clinicians, biologists and engineers work to develop new diagnostic technologies, which will be invaluable tools for combatting AMR.
Example technologies and programmes include:
- Novel, point-of care diagnostics solutions, called Dragonfly and Lacewing, for the detection of infectious diseases. These technologies are suitable for use in low resource and remote settings and are been developed and validated for a range of human, environmental and veterinary applications.
