Antimicrobial resistance describes the ability of a micro-organism to resist the action of antimicrobial drugs. This is important as it can make the treatment of infections more difficult and increase hospital costs. Undertaking laboratory testing of organisms causing infections can play a role in deciding the most effective treatment options.
HAIs are infections that are acquired as a result of healthcare interventions. There are a number of factors that can increase the risk of acquiring an infection, but high standards of infection control practice minimize the risk of occurrence.
