- Ar gael fel goruchwyliwr ôl-raddedig
Trosolwyg
Rwy'n uwch-ddarlithydd mewn nyrsio oedolion yn Ysgol Gwyddorau Gofal Iechyd Prifysgol Caerdydd ac yn nyrs gofrestredig. Mae gen i ystod o brofiad o addysgu a dysgu israddedig ac ôl-raddedig ac rwy'n athro ac ymchwilydd cymwysedig. Ar hyn o bryd rwy'n arwain modiwl MSc dulliau ymchwil a modiwl traethawd hir adolygiad systematig MSc.
Mae fy meysydd o ddiddordeb mewn dulliau ymchwil ansoddol, synthesis tystiolaeth a phrofiadau defnyddwyr gwasanaethau gofal iechyd. Mae gennyf ddiddordeb arbennig mewn cefnogi ac astudio rôl defnyddwyr gwasanaeth wrth ddatblygu, trefnu a darparu gwasanaethau gofal iechyd, gan ganolbwyntio ar ryngwynebau a llwybrau mynediad at ofal iechyd.

Ymchwil
Ymchwil ansoddol
Ariannwyd fy PhD gan Ymchwil Iechyd a Gofal Cymru ac archwiliodd gynnwys cleifion mewn gwell adferiad ar ôl gofal (ERAS). Mae papurau a gyhoeddwyd yn seiliedig ar ganfyddiadau fy astudiaeth wedi nodi bod cleifion yn croesawu cyfleoedd i gymryd rhan weithredol yn eu gofal ond bod rhwystrau i'r cyfranogiad hwn. Mae fy nghyd-awdur a minnau'n nodi bod angen i nyrsys deimlo eu bod wedi'u grymuso i fabwysiadu strategaethau a all ganiatáu ar gyfer gwahanol anghenion gwybodaeth a heriau cyfathrebu, yn hytrach na dull tadol un maint sy'n addas i bawb. Rydym yn cynnig model i gefnogi dull sy'n canolbwyntio ar y claf ac yn unigol o ran cyfranogiad cleifion. Mae papur arall yn helpu i lywio meddwl am y defnydd o lwybrau gofal fel ERAS mewn perthynas â darparu gwasanaethau trwy ganolbwyntio ar berthynas â chleifion nyrsio a rhyngweithio cleifion â chleifion. Mae'r dull hwn yn cynnwys syniadau o'r hyn y mae cyfranogiad cleifion gweithredol yn ei olygu mewn gwirionedd, yn hytrach na mathau mwy goddefol o gyfranogiad sy'n canolbwyntio'n bennaf ar weithwyr gofal iechyd proffesiynol sy'n hwyluso ymwneud â chwmpas cul, a bennwyd ymlaen llaw.
Ymchwil pellach
Bydd ymchwil bellach yn cynnwys cymryd y dull a gynigir yn seiliedig ar fy nghanfyddiadau PhD i glinigau a meysydd gofal eraill i brofi'r model hwn ar waith i weld a yw'n a) yn annog nyrsys a chleifion i fyfyrio a b) a yw oedi'r ddarpariaeth wybodaeth weddol ddi-baid i gymryd amser i adlewyrchu yn gwneud pethau'n heriol o ran rheoli amser, neu os cyflwynir unrhyw ganlyniadau anfwriadol niweidiol sy'n anodd eu rhagweld y tu allan i amgylchedd 'byd go iawn'.
Gall ymchwil bellach hefyd archwilio beth yw hi am nyrsys unigol sy'n eu hatal rhag darparu gofal unigol, ac i'r gwrthwyneb, beth yw hi am y nyrsys hynny sy'n teimlo eu bod wedi'u grymuso i deilwra eu hymgynghoriadau â chleifion. A oes ffactorau unigol neu sefydliadol penodol a all ddylanwadu ar hyn a sut y gellir goresgyn y rhain (neu harneisio)?
Mae fy nghanfyddiadau PhD hefyd wedi nodi bod angen ymchwil bellach o ran perthnasoedd cleifion a rhyngweithio yng nghyd-destun damcaniaethau presennol a sut y gellid defnyddio hyn i gefnogi gwell canlyniadau a phrofiadau cleifion.
Synthesis Tystiolaeth
Roeddwn yn rhan o dîm bach a gynhaliodd adolygiad systematig o brofiadau cleifion o imiwnotherapi canser sydd ar hyn o bryd yn cael ei adolygu mewn cyfnodolyn rhyngwladol blaenllaw. Mae canfyddiadau cynnar eisoes wedi'u rhannu mewn cynadleddau rhyngwladol a chenedlaethol. Ar hyn o bryd rwy'n rhan o dîm sy'n cynnal adolygiad systematig sy'n canolbwyntio ar fynediad, derbyn a chadw at adsefydlu canser (fel rhan o'r prosiect IPREHAB a ariennir gan NIHR).
Rwy'n cyfrannu at bolisi ac ymarfer gofal iechyd rhyngwladol trwy fy ngwaith fel Cydweithredwr Maes ac Awdur Gwyddonol ar gyfer Sefydliad Joanna Briggs (JBI), sefydliad byd-eang sy'n hyrwyddo ac yn cefnogi penderfyniadau sy'n seiliedig ar dystiolaeth sy'n gwella darpariaeth gwasanaethau iechyd ac iechyd. Rwyf hefyd yn aelod gweithredol o grŵp llywio Canolfan Gofal sy'n Seiliedig ar Dystiolaeth Cymru, Canolfan Ragoriaeth JBI sy'n ymwneud â synthesis tystiolaeth a datblygu canllawiau clinigol.
Addysgu
Mae gen i arbenigedd eang a phrofiad o gyflwyno, arloesi, trefnu a chefnogi addysgu, dysgu ac asesu ar draws rhaglenni cymhleth, israddedig ac ôl-raddedig, gweithwyr iechyd proffesiynol, gweithio gyda myfyrwyr proffesiynol iechyd cartref a rhyngwladol. Fy meysydd arbenigedd craidd yw cynnwys cleifion, diogelwch cleifion a gwella gwasanaethau. Er mwyn sicrhau bod fy addysgu yn cael ei arwain gan ymchwil a'i hysbysu, rwy'n cymryd rhan weithredol mewn ymchwil a synthesis tystiolaeth cysylltiedig. Mae fy ngwaith fel athro, arweinydd modiwl a goruchwyliwr yn dangos fy nghyfraniad sylweddol ar draws pob lefel academaidd a'm gallu i weithio'n ddi-dor ar draws ffiniau disgyblaeth.
Mae gen i brofiad sylweddol o arwain modiwlau ar lefelau israddedig ac ôl-raddedig ac ar hyn o bryd rwy'n arweinydd modiwl modiwl traethawd hir MSc Adolygiad Systematig a modiwl craidd dulliau ymchwil MSc.
Rwy'n goruchwylio myfyrwyr PhD cartref a rhyngwladol, myfyrwyr BN a myfyrwyr traethawd hir MSc o wahanol broffesiynau gofal iechyd ac rwyf hefyd yn diwtor personol profiadol. Mae prosiectau traethawd hir MSc a gwblhawyd yn ddiweddar yn cynnwys:
- Mae therapyddion galwedigaethol yn profi a barn gan ddefnyddio fideogynadledda mewn therapi llaw cleifion allanol yn ystod pandemig COVID-19.
- Gwerthusiad proses o'r ymyrraeth therapi yn yr uned trawma.
- Gweithredu rhaglen hyfforddi i alluogi dietegwyr sy'n gweithio mewn gofal acíwt i adnabod a diagnosio diffyg maeth yn gyson.
- Effeithiolrwydd cod ffug yn y fan a'r lle wrth wella sgiliau seicomotor mewn darparwyr gofal iechyd. Adolygiad systematig.
- Adolygiad systematig i bennu effeithiolrwydd tamsulosin fel therapi meddygol wrth drin cadw dwys o wrin eilaidd i ehangu prostatig annigonol.
Bywgraffiad
Yn dilyn gyrfa mewn llywodraeth leol, fe wnes i ailhyfforddi fel nyrs sy'n oedolion gan ennill fy ngradd o Brifysgol Abertawe yn 2008. Roeddwn i'n ffodus o gael ysgoloriaeth gan Brifysgol Abertawe i gefnogi fy MSc mewn Iechyd Cyhoeddus a Gweithio mewn Partneriaeth, gan astudio tra'n gweithio fel nyrs staff. Ar ôl cwblhau fy MSc, treuliais amser yn gweithio gydag Iechyd Cyhoeddus Cymru fel rhan o raglen gwella ansawdd genedlaethol. Arweiniodd y profiad hwn fi at ddatblygu fy astudiaeth ymchwil PhD sy'n archwilio cyfranogiad cleifion mewn menter diogelwch cleifion, a ariannwyd gan Ymchwil Iechyd a Gofal Cymru. Cefais fy mhenodi'n ddarlithydd mewn nyrsio oedolion ym Mhrifysgol Caerdydd yn 2014 ac ar hyn o bryd rwy'n uwch-ddarlithydd mewn nyrsio oedolion yn yr ysgol gwyddorau gofal iechyd.
