Comisiynodd Llywodraeth Cymru yr adolygiad ym mis Mehefin 2014, gan wireddu ymrwymiad i gynnal ymarfer o’r fath wedi i’r tri ymgynghoriad gael eu cwblhau. Gofynnwyd i Mrs Lloyd, gyda chymorth grŵp cyfeirio bach â phrofiad o newid mawr yng ngwasanaethau’r GIG, asesu effeithiolrwydd y prosesau a’r canllawiau presennol ac ystyried pa welliannau a allai fod yn angenrheidiol.
The Welsh Government commissioned the review in June 2014, fulfilling a commitment to undertake such an exercise when all three consultations were complete. Mrs Lloyd, supported by a small reference group with experience of major service change in the NHS, was asked to provide an assessment of the effectiveness of the current processes and guidance and consider what improvements may be necessary.
