Mae’n cefnogi’r gwaith ychwanegol y mae cyfarwyddwr meddygol Bwrdd Iechyd Prifysgol Hywel Dda yn ei wneud ar hyn o bryd.
However, Professor Palmer believes further work is needed to understand the ways in which changes to the classification of palliative care cases and other matters may have had an impact on the RAMI score. He supports the additional work the medical director at Hywel Dda University Health Board is currently carrying out.
