Er gwaetha heriau’r pandemig, llwyddodd naw o’r un ar ddeg o sefydliadau’r GIG weithredu o fewn eu cyllidebau yn 2020-21. Dim ond Bwrdd Iechyd Hywel Dda a Bwrdd Iechyd Prifysgol Bae Abertawe a fethodd â mantoli eu cyllidebau yn ystod y flwyddyn, gan adrodd diffygion yn unol â’u cynlluniau gwreiddiol a ddatblygwyd cyn y pandemig. Yr alldro cyffredinol ar gyfer GIG Cymru oedd diffyg o £48m, i lawr o £89m yn 2019-20.
Despite the challenges posed by the pandemic, nine out of the eleven NHS organisations operated within their budgets in 2020-21. Only Hywel Dda and Swansea Bay University Health Boards were unable to balance their books in-year, reporting deficits in line with their initial plans developed prior to the pandemic. The overall outturn for NHS Wales was a deficit of £48m, down from £89m in 2019-20.
