Fodd bynnag, mae yna sawl her fawr. Mae’r galw’n cynyddu wrth i’n cymdeithas heneiddio, mae gan gleifion wrth gwrs ddisgwyliadau uchel o’r GIG, ac mae gwelliant parhaus yn y triniaethau sydd ar gael. Yr her yw ateb y disgwyliadau hyn pan fo llai o arian ar gael. Rhaid inni sicrhau ein bod yn defnyddio’n hadnoddau gwerthfawr yn effeithiol trwy sicrhau gofal sy’n rhoi gwerth mawr am arian, a hynny bob amser. Mae’n hollbwysig cael dull sy’n seiliedig ar dystiolaeth i benderfynu pa driniaethau a ddylai fod ar gael fel mater o drefn yn system y GIG. Mae hynny’n rhoi sicrwydd i bawb fod arian yn cael ei wario ar gael manteision clir i iechyd, y gymdeithas a’r economi, ni waeth beth fo’r afiechyd y maen nhw neu eu hanwyliaid yn ddigon anffodus i ddioddef ohono.
However, there are significant challenges.  Demand is increasing as our society ages, patients rightly have high expectations of the NHS and there is continuous improvement in the treatments available.  The challenge is to meet these expectations when there is less money available.  We must ensure we are using our precious resources effectively by delivering high value care at all times.  An evidence based approach to determine what treatments should be routinely available in the NHS system is crucial.  It provides everyone with the assurance money is being spent to bring about clear health, social and economic benefits, regardless of whatever disease they or their loved ones have the misfortune to suffer.
