Daw’r penderfyniad i newid y system bresennol yn sgil yr Ymchwiliad i Harold Shipman ac adolygiadau eraill megis Adroddiad Francis i Ymddiriedolaeth GIG Canolbarth Swydd Stafford. Ar ôl ei diwygio, bydd y system yn fodd i atal camweddau, a hyrwyddo dysgu a gwella.
The decision to change the current system follows the Shipman Inquiry and other reviews such as the Francis Report into Mid Staffordshire NHS Trust. The reforms will ensure there are safeguards in the system to prevent wrongdoing and to promote learning and improvement.
