Trosolwyg
Rwy'n ymchwilydd cymdeithasol profiadol ac yn ddarlithydd yng Nghanolfan Ymchwil Marie Cure (Is-adran Meddygaeth Poblogaeth) gyda chefndir mewn gwyddorau cymdeithasol a pholisi. Rwyf wedi sefydlu arbenigedd a phortffolio o fewn ymchwil iechyd a gofal gyda ffocws ar ddulliau ymchwil ansoddol.
Mae fy ymchwil bresennol yn canolbwyntio ar brofiadau cleifion ar hyd llwybrau canser a diwedd oes gyda diddordeb penodol mewn gofal diwedd oes a lliniarol, cyfathrebu cleifion - clinigwyr, cydgynhyrchu gan gynnwys gwneud penderfyniadau ar y cyd, llythrennedd iechyd a marwolaeth, anghydraddoldebau ac ansawdd bywyd.

Ymchwil
Ymchwil cyfredol
Ar hyn o bryd mae fy ymchwil yn canolbwyntio ar optimeiddio profiad cleifion ar hyd llwybrau canser a diwedd oes, yn ogystal ag archwilio polisïau a chysyniadau sy'n ymwneud â llythrennedd marwolaeth. Mae'r rhain yn cynnwys:
Mapio systemau: Blwyddyn olaf bywyd a gofal heb ei drefnu.
Adolygiad Cyflym: Canfyddiadau cleifion, rhoddwyr gofal a gweithwyr gofal iechyd proffesiynol cyffredinol ar rôl a gwerth gwasanaethau gofal lliniarol arbenigol: adolygiad cyflym (PaCERS).
Adolygiad Cyflym: Anghenion gwybodaeth a chyfathrebu cleifion â chanser datblygedig a'u rhoddwyr gofal (PaCERS). https://www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=434023
Adolygiad Realist: Sut mae dulliau gwneud penderfyniadau ar y cyd a chymhorthion cleifion yn dylanwadu ar benderfyniadau triniaeth ar gyfer cleifion â chanser anwelladwy datblygedig. PROSPERO: https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42021251690
Y gwaith hwn yw Marie Curie, Canolfan Ymchwil Canser Cymru (WCRC), a ariennir gan CRUK. Rwyf hefyd yn cynnal ymchwil ansoddol ar gyfer treialon canser:
(VALTIVE1) Astudiaeth ar ddilysu Tie2 fel y biomarciwr ymateb fasgwlaidd tiwmor cyntaf ar gyfer atalyddion VEGF. Astudiaeth ansoddol o ganfyddiadau cleifion o gael y prawf biomarciwr Tie2 a sut y gallent deimlo pe bai eu triniaeth yn cael ei newid yn seiliedig ar ganlyniadau'r prawf.
(CWMPAS 2) Astudiaeth o Chemoradiotherapi mewn canser Oesoffagaidd gan gynnwys ymateb PET a dos Prosiectau uwchgyfeirio. Dadansoddiad ansoddol o brofiadau cleifion a chanfyddiadau o gymryd rhan mewn treial o chemoradiotherapi diffiniol uwch (dCRT) o'i gymharu â dos safonol ac o'r ddwy gyfundrefn cyffuriau a yrrir gan PET.
(CHRONOS) Astudiaeth o Ganlyniadau Ymchwil Iechyd Cymharol Llawfeddygaeth Newydd mewn canser y prostad. Ymchwil ansoddol gyda chleifion a staff yn cymryd rhan mewn treial, gwneud penderfyniadau ar gyfer llwybrau trin canser y prostad ac ansawdd bywyd cleifion.
Ymchwil blaenorol:
(PLUS): Cyfeiriadau Fferyllfa ar gyfer Astudiaeth Symptomau Canser yr Ysgyfaint. Archwilio derbynioldeb a dichonoldeb gwasanaeth atgyfeirio fferyllfeydd ar gyfer canser yr ysgyfaint a oedd yn canolbwyntio ar bobl o gymunedau economaidd-gymdeithasol is.
(PREDICT-CAT) Rhagweld Budd-dal Hunan-gofnodedig i gleifion cataract, Penderfyniad Cefnogol. Gwneud a graddnodi cyfleustodau Iechyd ar gyfer Llawfeddygaeth Cataract. Astudiaeth dulliau cymysg sy'n datblygu a phrofi defnyddwyr ymyrraeth cymorth penderfyniadau ar gyfer cleifion cataract.
(Gofal Iechyd Darbodus)- archwilio canfyddiadau a phrofiadau clinigwyr, cleifion a'r cyhoedd ynghylch cysyniad y polisi gofal iechyd darbodus, gan ganolbwyntio ar gydgynhyrchu a gwneud penderfyniadau ar y cyd.
Anghenion hyfforddi a datblygu gweithwyr gofal cymdeithasol sy'n cefnogi pobl hŷn ag anableddau dysgu mewn perthynas â'u hiechyd.
