Roedd yr adolygiad annibynnol yn 2014 ar y gofal ar gyfer pobl hŷn ac eiddil yn Ysbytai Tywysoges Cymru a Chastell-nedd Port Talbot ym Mwrdd Iechyd Prifysgol Bro Morgannwg yn codi sawl pryder ynghylch ansawdd y gofal ar rai o wardiau'r ysbytai hyn ynghyd â rhai gweithdrefnau clinigol a rheoli. Cadarnhaodd yr adolygiad dilynol yn 2015 fod y Bwrdd Iechyd wedi gwneud cynnydd sylweddol o ran yr 14 o argymhellion ac, yn bwysicach oll, y gellid sicrhau'r cyhoedd bellach bod y gofal ar gyfer pobl hŷn ac eiddil wedi gwella. Nododd yr adolygwyr rai meysydd lle'r oedd angen cynnydd pellach. Mae'r Bwrdd Iechyd wedi gweithio gyda'r gymuned leol a'i staff ac wedi gwrando arnynt er mwyn mynd i'r afael â’r meysydd hyn a sicrhau gwelliannau ar draws y Bwrdd.
The 2014 independent review into the care of frail older people at the Princess of Wales and Neath Port Talbot Hospitals within Abertawe, Bro Morgannwg University Health Board identified a number of concerns about the quality of care on some of the wards in these hospitals and about some clinical and managerial processes.  A follow up review during 2015 confirmed the health board had made considerable progress against the original 14 recommendations and importantly the public could be reassured that the care of frail older people had much improved. The reviewers identified some areas where further progress was required. The health board has worked with and listened to its local communities and staff to address these and embed improvements across the entire health board.
