Yes. A trainee must continue to have a named clinical and educational supervisor during their acting up period. This may be with the pre-existing supervisor or, for the duration of the acting up period, the responsibility may be transferred to another supervisor on the scheme (a decision in this respect would probably be based on locality). All supervisory arrangements must be specified in advance of post commencement and be agreed with both supervisor(s) and TPD.
Whether in working hours or on-call, a trainee must have access to consultant colleagues for advice and support on clinical & legal matters at all times.
