The purpose of maintaining such records is to enable the RCP to be aware of relevant interests and to provide a source of reference should that be needed.
The RCP Declaration of Interests policy defines the formal procedure for this and applies to anyone who could be thought of as participating in RCP activities and decisions - described in the policy as RCP Contributors. Linked to this, it is also appropriate for medically qualified RCP Contributors to confirm that they are of good standing in terms of registration with regulatory bodies.
