Fel rwyf eisoes wedi dweud yn ystod cyfnodau o alw mawr, mae pobl yn troi’n naturiol at y system iechyd am dawelwch meddwl, er ei bod eisoes dan bwysau ac er nad yr ysbyty yw’r lle gorau iddynt, o reidrwydd. Gall y pwysau ar ofal heb ei drefnu effeithio ar y system gyfan wrth i gleifion sy’n cyrraedd yr ysbyty orfod aros yn hwy i gael eu derbyn neu eu gweld, ac wrth i lawdriniaethau gael eu gohirio ac ambiwlansys gael eu rhwystro rhag ymateb i alwadau eraill.
As I have stated previously during periods of high demand, an already pressured health system becomes the default “place of safety” even when the best place for such people may not be in hospital.  The pressures in unscheduled care have an impact across the whole system with patients arriving at hospital facing longer waits to be admitted or seen; scheduled operations being postponed and ambulances being delayed from attending other calls.
