Mae Bwrdd Iechyd Prifysgol Bae Abertawe hefyd wedi datblygu ei system electronig ei hun ar gyfer rheoli llif cleifion, o'r enw Signal. Mae’r system hon yn helpu i fynd ymhellach eto i wella diogelwch cleifion a dileu unrhyw oedi o ran gofal cleifion. Mae diddordeb gan fyrddau iechyd eraill yng Nghymru mewn mabwysiadu'r system.
Swansea Bay University Health Board has also developed its own electronic system for patient flow, called Signal. This is further helping to improve patient safety and remove delays in patient care. Other Health Boards in Wales are interested in adopting the system.
