Evidence-based medicine is like when you are trying to figure out the best way to do something, like tying your shoes. You ask your parents or teachers how they do it, and they may tell you different ways. But how do you know which way is the best and easiest way?
This is where evidence-based medicine comes in. Doctors and researchers ask questions like "What is the best way to treat a cough?" or "What is the best way to prevent a disease?"
They then look at all the different ways people have tried to treat or prevent the disease and see which way works the best. They do this by looking at scientific studies that test different treatments or methods.
Once they figure out the best way, they tell other doctors and nurses about it so that they can use it too. This helps everyone make sure they are doing the right thing and that they are doing what is best for their patients.
