Sefydlwyd y Comisiwn Bevan yn 2008 i sicrhau bod y GIG yng Nghymru yn cadw at yr egwyddorion sylfaenol a osodwyd gan Aneurin Bevan ym 1948.  Dros y chwe mlynedd ddiwethaf, mae gwaith y Comisiwn wedi ychwanegu gwerth sylweddol at waith Llywodraeth Cymru a GIG Cymru, gan gynnwys datblygu egwyddorion Comisiwn Bevan ac yn fwy diweddar, y syniad o ofal iechyd darbodus.
The Bevan Commission was set up in 2008 to ensure the NHS in Wales remains true to its founding principles as set out by Aneurin Bevan in 1948. Over the last six years, the Commission’s work has added significant value to the work of the Welsh Government and the NHS in Wales, including the development of the Bevan Commission principles and, more recently, the idea of prudent healthcare.
