So you may want to enroll your child in a clinical study.

You have asked all the questions and understand what will be involved. You've met the team and feel comfortable about what you are asked to do and the amount of time it will take.

But you may still have questions about cost. Some information may be in the informed consent form, but it is always good to ask:

• Will I have to pay for travel (gas, bus, subway or cab fare) and parking?
• What if I need a sitter for my other children?
• Are there funds to help me if I have to miss work without pay?
• What if there is an overnight stay?
• Will meals be provided?
• What will the study pay for and what is my insurance expected
  to pay for, if I have it?

These are practical questions. But they are as important as the study facts that you need to know. Be sure to ask! Find out whether there are costs when you get a study medication and what happens when a study ends - do you need to pay for medicines, for instance? There is no single answer because it depends a lot on the study. But getting the details is the best way to make sure that your participation in a study is successful. The study team will want to make it as easy as possible by working with you to do things like scheduling study visits at times when you will already be seeing the doctor. There may be other things that can make it convenient, so it is important to ask.
