Clinic/registration location

The first thing to do is register at the Cardiology Clinic on Unit 4A, located on the 4th floor of the hospital’s Atrium wing.

When visiting SickKids an identification (ID) band will be placed on your child and must be worn on their arm or ankle at all times. To ensure your child is receiving the right care during their stay, the care team will use the ID band to check their name, date of birth and medical record number. If your child is sleeping, we’ll make sure to scan the ID band quickly and quietly so that we don’t disturb your child.  

The ID band is made of soft, latex-free material. There are two colours of ID bands: a black ID band indicates that your child has an allergy and a white ID band indicates there is no allergy. The allergy is not printed on the ID band, the care team will review the allergy in our electronic health record.

If your child’s ID band has fallen off or the information is incorrect, be sure to tell your care team. If they are not wearing an ID band or if they have the wrong one, it can lead to errors or delays that can result in the wrong care for your child.

Staff will always look at or scan the ID band before providing care to your child. This may involve

  • Asking parents or patients for two patient identifiers, such as the patient's full name and date of birth;
  • Scanning a barcode on the ID band to confirm the patient’s identity; or
  • Looking at the information on the ID band.

If you or your child are sick before your appointment

Call the clinic if you or your child have had a cold, cough, diarrhea, fever or rash within two days of your appointment, or have been sick with or exposed to chicken pox in the last three weeks. Your appointment may need to be rescheduled. 

Tell the clerk, nurse or doctor if your child has been in a hospital outside of Canada within the last 12 months. 

If you cannot come to your child’s appointment, it is important that you call the clinic as soon as possible to cancel and reschedule.

Be on time

Please ensure you arrive 30 minutes prior to your scheduled appointment to allow for time to register, unless you are told otherwise.  

If you are late, you may have to wait for other patients to be seen first. Allow lots of time to get to the hospital. It can take some time to get used to finding your way around and it is important to be on time for your child’s appointment. Staff will try to see your child as close to your appointment time as possible. Please understand that some patients being seen ahead of you may need more time than expected, and this can cause delay for others.
