Sefydlwyd y broses Gweithio i Wella o dan Reoliadau'r Gwasanaeth Iechyd Gwladol (Trefniadau Pryderon, Cwynion ac Iawn) (Cymru) 2011. Mae’n rhoi un broses i bobl godi pryder neu gwyn am wasanaethau GIG Cymru. Mae hefyd yn gosod y broses am ystyried a chynnig iawn pan achosir niwed mewn cysylltiad â’r gofal hwnnw.
The “Putting Things Right” process was set up under the National Health Service (Concerns, Complaints and Redress Arrangements) (Wales) Regulations 2011. It gives people a single process for raising a concern or complaint about NHS services. It also sets out the process for considering and offering redress where harm, associated with that care, has been caused.
