Mae RCEM wedi sôn am yr angen brys i newid o fodel gwasanaeth gyda niferoedd diderfyn o bobl yn mynd i adrannau argyfwng mewn ffordd heb ei chydgysylltu, a all ei gwneud yn anodd cadw staff a chleifion yn ddiogel.
RCEM has spoken of an urgent need to change from a service model with unlimited numbers of people attending emergency departments in an uncoordinated way, which can make it difficult to keep staff and patients safe.
