Do I need to use the Cerner Health PHR as part of the MyKids Patient Portal?

No, the MyKids Patient Portal is completely separate from the Cerner Health PHR. The PHR is available only if you choose to use it. There is no need to use the PHR in order to receive the benefits of the MyKids Patient Portal. Any information that you enter in the PHR will not be shared with your providers unless you print it out and share it with them.
