Cafodd y model gofal newydd ei gyflwyno ym mis Awst 2014. Gwnaeth Bwrdd Iechyd Prifysgol Hywel Dda newidiadau dilynol i wasanaethau pediatrig ym mis Hydref 2014 - cafodd gwasanaethau mewnol i blant eu canoli yn Ysbyty Glangwili ac agorwyd uned asesu pediatrig 12 awr newydd yn Ysbyty Llwynhelyg. Ni chafodd y newidiadau pediatrig eu cyfeirio at Weinidogion i wneud penderfyniad yn eu cylch.
The new model of care was introduced in August 2014. Hywel Dda University Health Board subsequently made changes to paediatric services in October 2014 – inpatient children’s services were concentrated at Glangwili Hospital and a new 12-hour paediatric assessment unit was opened at Withybush Hospital. The paediatric changes were not referred for Ministerial determination.
