The most important thing you can do to ensure good care and prevent medical errors is to be an active partner in your own healthcare. You have a right to ask questions of anyone involved in your care — and we encourage you to do so. Make a list of your symptoms and any questions you have to ask the doctor or nurse. Take notes (or have a family or friend do so) when medical personnel talk to you to help you remember. And you should feel very free to speak up if you have any questions or concerns.
