The challenge is how to quickly determine which patients really need powerful drugs and which do not. Good antibiotic stewardship is a race against the clock. If patients need those drugs and don’t receive them in a timely manner, it may become too late to help them.
Bacteria are constantly evolving, so even if we are able to develop an arsenal of new drugs, we will always need to stay one step ahead of the bugs. For that reason, we need to use diagnostics tests to help doctors prescribe antibiotics more accurately.
