How primary care doctors choose the specialists to refer their patients

Dr. Kirsch, a blogging gastroenterologist lists some of the reasons why certain medical specialists are chosen:

- Reciprocity - patients are referred in both directions
- Personal relationships
- Corporate enforcement keeping consultations within the network
- Economic pressure exerted by consultants to maintain referrals. I have seen this happen.
- Specialist willingness to do tests and procedures on request
- Habit
- Patient or family request
