Mae Llywodraeth Cymru wedi datblygu nifer o ddangosyddion canlyniad a sicrwydd i fesur sut mae gwasanaethau gofal critigol yn gwella yng Nghymru. Mae cynnydd yn dangos bod gwasanaethau gofal critigol yn datblygu:Mae cyfraddau goroesi'n gwella – mae nifer y cleifion sy'n cael eu trosglwyddo'n ôl i'r ward ar ôl cael eu derbyn i uned gofal critigol yn cynyddu. Yn 2012, cafodd ychydig dros 80% o gleifion eu rhyddhau i ward arall, sef cynnydd o'i gymharu â 79% yn 2011;Mae’r GIG yn bodloni'r galw am ofal critigol, sydd wedi bod yn cynyddu'n araf dros gyfnod. Yn 2011 roedd 8,991 o dderbyniadau ac yn 2012 roedd 9,887 o dderbyniadau – cynnydd o 896 o dderbyniadau, bron 10%.Prin iawn yw'r aildderbyniadau i ofal critigol o fewn 48 awr – llai na 2% o'r holl gleifion sy'n cael eu rhyddhau, sy'n arwydd bod y gofal mewn wardiau a'r broses ryddhau yn effeithiol.Ers cyflwyno'r rhwydweithiau gofal critigol, mae gwelliannau wedi digwydd o ran trosglwyddo diogel ar gyfer pobl sy'n ddifrifol wael drwy hyfforddiant ac archwilio parhaus – mae 80% o'r holl drosglwyddiadau'n cael eu barnu'n dda neu'n rhagorol.Mae holiadur adborth gofalwyr y Gymdeithas Gofal Dwys wedi cael ei gyflwyno i gael barn gofalwyr. Mae ysbytai sydd wedi cymryd rhan wedi nodi cyfraddau boddhad rhagorol o ran cyfathrebu, cyfleusterau a staff meddygol a nyrsio.
The Welsh Government has developed a number of outcome and assurance indicators to measure how critical care services are improving in Wales. Progress against these, showing that critical care services are developing:Survival rates are improving - the number of patients being transferred back to the ward after being admitted to a critical care unit is increasing. In 2012, just over 80% of patients were discharged to another ward, up from 79% in 2011;The NHS is meeting the demand for critical care, which has been slowly increasing over time. In 2011 there were 8,991 admissions and in 2012 there were 9,887 admissions – an increase of 896 admissions, almost 10%;Readmissions to critical care within 48 hours are very low – less than 2% of all discharges, indicating ward-based care and the discharge process are effective;Since the introduction of the critical care networks, improvements have been made in the safe transfer of people who are critically ill between hospitals through training and continuous audit - 80% of all transfers are graded as good or excellent;The Intensive Care Society’s carers’ feedback questionnaire has been introduced to obtain the views of carers.  Hospitals which have taken part have reported excellent satisfaction rates on communication, facilities and medical and nursing staff.
