Doctor A was a rehabilitation physician working in a public hospital day rehabilitation unit. Prior to patients commencing the day rehab program (where they are admitted inpatients on each day they attend), they have an initial outpatient visit to determine their eligibility for the program. The referrals from the GPs always name one of the rehabilitation specialists. Doctor A wanted to know whether Doctor B could see the patient for the initial outpatient assessment even though the referral was to Doctor A.
