Ynghyd â galluogi un ffordd o fesur amseroedd aros yn y system iechyd sy'n fwy cywir, mae'r angen i safoni'r hyn sy'n cael ei fesur wedi bod yn gyfle unigryw i adolygu ansawdd y llwybrau a mynd i'r afael â'r amrywiaeth o ran ymarfer clinigol ledled Cymru. Mae hwn yn ddarn sylweddol o waith i'r GIG. Hoffwn dalu teyrnged i'r holl waith arweiniol a wnaed gan Rwydwaith Canser Cymru a'r gwaith ymgysylltu a pharatoi a wnaed gan y byrddau iechyd ac Ymddiriedolaeth GIG Felindre dros y flwyddyn ddiwethaf.
As well as enabling a more accurate, single measure of waits in the health system, the need to standardise what is being measured has proved to be a unique opportunity to review the quality of pathways and tackle variation in clinical practice across Wales. This is a significant piece of work for the NHS. I pay tribute to the considerable leadership from the Wales Cancer Network and engagement from the health boards and Velindre NHS Trust over the past year to prepare.
