Mae’r Athro Palmer yn cefnogi’r broses o adolygu achosion marwolaethau, sydd wedi’i sefydlu ar gyfer pob marwolaeth yn ysbytai Cymru. Maes lle mae Cymru’n arwain y DU yw hwn. Mae’n cynghori ar sut y gellir cryfhau’r broses adolygu hon ymhellach trwy gysondeb gwell ac ymgysylltu clinigol. Mae’r Athro Palmer hefyd yn gwneud  argymhellion i wella codio clinigol, cyfranogiad mewn archwiliadau clinigol cenedlaethol a dehongli data ar gyfer Byrddau.
Professor Palmer supports the mortality case review process, which is in place for all deaths in Welsh hospitals – this is an area in which Wales leads the UK. He advises ways in which this review process can be further strengthened by improved consistency and clinical engagement. Professor Palmer also makes recommendations to improve clinical coding, participation in national clinical audits and data interpretation for Boards.
