Randomization, allocation concealment, and blinding Dr. Haq Nawaz will use software developed by the Johns Hopkins Division of Oncology Biostatistics to randomize patients to the usual care and educational intervention groups. Dr. Nawaz will keep group assignments in consecutively numbered opaque envelops and will reveal the assignment only to the nurse patient educator when the intervention is assigned. All other study personnel who collect and manage data will remain blind to study assignment. Patients will also be blind to group assignment throughout the trial.
