I worked in a hospital where no one could prescribe more than two doses of meropenem without getting approval from a microbiologist or infectious diseases physician. It was meant to reduce indiscriminate prescribing of broad spectrum antibiotics. However, it felt like everyone with any signs of infection now got their two doses of meropenem, and more was being used than before that rule. Has anyone else had experiences like this? Or evidence for or against such policies?
