"Mae'r galw ar adrannau argyfwng hefyd yn effeithio ar ddarpariaeth triniaethau a gynlluniwyd mewn ysbytai. Mae'r sefyllfa'n waeth oherwydd bod meddygon yn lleihau eu horiau o ganlyniad i newidiadau i reolau treth pensiwn gan Lywodraeth y DU. Erbyn diwedd mis Rhagfyr roedd hyn wedi arwain at golli tua 3,200 o sesiynau, gan effeithio ar bron i 27,000 o gleifion. Rwyf wedi galw ar Lywodraeth y DU i ddatrys y mater hwn ar fyrder.
Demand on emergency departments is also affecting the delivery of planned treatments at hospitals. This is being made worse by doctors reducing their hours because of changes to HMRC pension tax rules by the UK Government. By the end of December, this had led to about 3,200 sessions lost, affecting nearly 27,000 patients. I have called on the UK Government to resolve this matter urgently.
