In this stats release, locums are only counted if they have actively worked in the quarter and the sessions were recorded through Locum Hub Wales.
Yn y datganiad ystadegol hwn, dim ond os ydynt wedi gweithio yn ystod y chwarter, a’u sesiynau wedi’u cofnodi ar Locum Hub Wales, y caiff staff locwm eu cyfrif.
