Mae casgliadau'r Adolygiad yn cynnig tystiolaeth bod y GIG yn gweithio'n galed i gynnal perfformiad a lefelau cyflawni. Fodd bynnag, ceir tystiolaeth hefyd eleni fod lefel y galw am rai gwasanaethau wedi cynyddu'n gyflymach na'r disgwyl. Mae hyn wedi bod yn arbennig o wir o fewn y system gofal heb ei drefnu. Rydym wedi gweld cynnydd sylweddol yn nifer y bobl hŷn a dderbynnir i'n Hadrannau Damweiniau ac Achosion Brys. Mae cyfnodau arosiadau yn yr ysbyty yn tueddu i fod yn hirach ar gyfer pobl hŷn, ac yn aml mae angen triniaethau mwy costus arnynt.  Roedd gan Fyrddau Iechyd gynlluniau i ymdopi â galw cynyddol, ond mae'r cynnydd wedi bod yn ddigynsail eleni, gan roi mwy o bwysau ar adnoddau.
The conclusions from the Review provide evidence the NHS is working hard to maintain performance and delivery levels. However, there is also evidence this year, the level of demand for some services has grown more rapidly than we anticipated. This has been particularly prevalent within the unscheduled care system. We have seen a significant increase in the number of older people admitted to our A&E Departments.  Lengths of stay in hospital tend to be longer for older people, and they often require more expensive treatments.  Health Boards did have plans to cope with increasing demand but the increases have been unprecedented this year, placing further pressure on their resources.
