This is an interim solution as it was identified that the data collected through the PP01W form did not capture referrals from all sources and health boards were not using consistent definitions.
Ateb interim yw hwn oherwydd nodwyd nad oedd y data a gasglwyd drwy’r ffurflen PP01W yn cynnwys cyfeiriadau o bob ffynhonnell ac nad oedd byrddau iechyd yn defnyddio diffiniadau cyson.
