Let's say a patient learns that his surgeon is brown, and requests the planned procedure be performed by a white surgeon instead. It may be ethically dubious to accommodate racism, but, in practice, such requests will often be accommodated, because the healthcare system has an obligation to provide care, and the relationship between a patient and their physician may be irreparably damaged by overt racism.

If racists must be accommodated, why not price in the negative externalities by charging a fee that can cover the cost of administration and rescheduling? If a patient asks to see a white doctor, their visit will be terminated, and they'll be rescheduled, but they'll also receive an invoice with a clear explanation for why they, unlike everyone else being served by the NHS, are on the hook for a few hundred quid. Repeat ad infinitum. If racists must plague society, society may as well make money off of them.

PS. The vast overwhelming majority of patients are decent or at least sufficiently well-socialized that they do not express overt racism. You're probably more likely to encounter sexism than racism, in healthcare. That said, my friends working in England have definitely noticed an increase in casual racism, primarily from patients, directed towards all categories of staff at their hospitals. Obviously my suggestion isn't serious, but this problem is very serious.
