This is the slowest part of the work and the only one a richer competitor cannot buy their way past. It is also the reason a referral holds instead of quietly leaking.
We call this step Credibility. You can call it trust.
A GP writes a referral. The patient goes home and searches your consultant's name. Sometimes the GP's front desk searches it first. What comes back decides whether the appointment actually happens. A registration number that resolves, published work that surfaces, and a hospital page confirming the job holds the referral. A stock photograph and three lines of marketing prose loses it to whoever looked more substantial.
When a patient asks an AI which doctor to see, it will name a hospital easily and a person reluctantly. Naming an individual doctor is a specific endorsement, and the system has almost no basis for it — unless your consultant's qualifications exist somewhere a machine can find and confirm against a source you do not control.
Your doctors stay invisible to the systems patients now ask. Not ranked badly — unnameable. And every referral you receive is one search away from leaking.
