Dyma'r ffactorau sydd wedi cyfrannu at gasgliadau adroddiad diweddar y Sefydliad ar gyfer Cydweithrediad a Datblygiad Economaidd, sef bod system gofal iechyd Cymru yn canolbwyntio ar ansawdd, a bod gwella ansawdd iechyd yn barhaus yn ymrwymiad sy'n rhan annatod a chyffredin o system gofal iechyd Cymru.
