Participant Recruitment:
Telephone communication was attempted with all patients who met the
inclusion criteria. Telephone contact information was available within
the CHLA hematology section database and the hospital’s Electronic
Medical Record system. Messages were left on voice-mail when available
and multiple calls were attempted to all existing phone numbers until
the patient was reached or it was determined that no current contact
information was available. Emails and/or letters were sent to patients
for whom telephone communication was not successful.
