The GMC guidance says: -
35 Decisions about who should take responsibility for continuing care or treatment after initial diagnosis or assessment should be based on the patient’s best interests, rather than on your convenience or the cost of the medicine and associated monitoring or follow-up.
36 Shared care requires the agreement of all parties, including the patient. Effective communication and continuing liaison between all parties to a shared care agreement are essential.
LMC Comment: This guidance needs to be implemented as in our experience most shared care is based on asking practices to take the responsibility based on cost (usually general practice is viewed as a free commodity!) And most shared care is imposed on GPs and rarely is the result of agreements on all sides.
