EMAR is an electronic system that helps doctors and nurses keep track of the medicines you take when you are in the hospital. When you go to the hospital, the doctor might give you different medicines to help you feel better. Each medicine has a special name and a certain amount that you need to take at a certain time.
EMAR helps make sure that you get the right medicine at the right time. Doctors and nurses use a computer to see which medicine you need to take and when you need to take it. They can also see if you have any allergies to any medicines, so they don't give you something that will make you sick.
It's like a special list that only the hospital workers can see, and they use it to make sure you get the medicine you need to feel better. With EMAR, patients are safer because they are less likely to get the wrong medicine or the wrong amount of medicine.
