Because you’re getting two CCTs at the end of your training and both need appropriate supervision, feedback and governance. Frequently a ‘combined’ report is 90%+ about the specialty with scarcely a mention of GIM. As GIM has a separate curriculum and separate requirements for experience, SLEs, procedures, CPD and audit, to name a few, some focus should be given to it set apart from the specialty. Thus also GIM reports that simply say “See specialty report” are not adequate (although there may be a few areas that this is acceptable eg research and management). However, f you’re doing Acute Medicine + GIM then you only need one report, because a 2nd report really would be exactly the same.
