Ar hyn o bryd, nid oes unrhyw adnodd sefydledig tebyg yn cael eu defnyddio i gynllunio'r gweithlu mewn lleoliadau gofal eraill, a dyna pam – drwy Grŵp Lefelau Staff Nyrsio Cymru Gyfan – rydym yn datblygu adnoddau newydd ac yn bwriadu cynnal profion ym mhob rhan o'r GIG yng Nghymru i ddatblygu'r sail dystiolaeth angenrheidiol. Yn anochel, ni ellir cyflawni'r broses hon na gwneud y gwaith ymgysylltu angenrheidiol â thimau ledled y wlad dros nos, ond mae'n hanfodol bod y gweithgorau'n cael yr amser sydd ei angen arnynt i bennu cwmpas y gwaith datblygu a'i wneud, ei dreialu, ei adolygu a'i gwblhau'n drylwyr. Os byddwn yn rhuthro i greu'r adnoddau hyn ac yn creu adnoddau nad ydynt yn addas at y diben, gallai hyn arwain at lefelau staff amhriodol o uchel a fyddai'n rhy gostus heb unrhyw fudd ychwanegol i'r claf neu, yn bwysicach, gallai arwain at niwed i'r claf gan fod lefelau staff yn rhy isel.
Currently, there are no similarly established workforce planning tools in use for other care settings which is why – through the All Wales Nurse Staffing Levels Group (AWNSLG) - we are building new tools and plan to undertake the testing across NHS Wales to develop the necessary evidence base. Inevitably, this process and the necessary engagement with teams throughout the country is not something that can be achieved overnight, but it is vital to allow the working groups the time they need to scope, undertake, pilot, review and complete the development work thoroughly. If we rush to produce these tools and get them wrong, they could either result in inappropriately high staffing levels which would be too costly with no added patient benefit, or more importantly, they could lead to patient harm due to staffing levels being too low.
