Mae dros 4 blynedd a hanner wedi pasio ers i bryderon gael eu codi am y tro cyntaf am y gofal a'r driniaeth ar ward Tawel Fan, ac mae'r adolygiad hwn wedi pwyso'n helaeth ar ganfyddiadau adroddiadau blaenorol. Daw â'r rhain ynghyd mewn un man defnyddiol, gan roi cyfle i ystyried y gwersi a ddysgwyd o'r gyfres hon o ymchwiliadau ac adolygiadau, ar gyfer Bwrdd Iechyd Prifysgol Betsi Cadwaladr a'r GIG yn ehangach.
It has been over 4 and half years since concerns were first raised regarding the care and treatment on Tawel Fan ward and this review has drawn heavily on the findings from previous reports. It helpfully brings these together into one place, providing the opportunity to reflect on the learning from this series of investigations and reviews, for BCU and the NHS more broadly.
