CSSD also stands for:
Central Sterile Supply Department ( See: Boshill Hospital part of Eastern Health, Australia. ) (As newcomer I cannot give URL. )
QUOTE: "CSSD is a specialised area responsible for the collecting, decontamination, assembling, packing, sterilisation, storing and distribution of a multiplicity of goods and equipment to areas in the hospital that provide patient care. "
Outside the context of hospitals, readers should note that CSSD also stands for:
Central School of Speech and Drama (London, UK).
Czech Social Democratic Party
Child Support Services Division (US)
Canadian Society for Social Development
Services or Supply
If the CSSD actually provide sterilisation services they will use Services. If they supply equipment and packs sterilised elsewhere they will use Supply.
Alternatively, it may depend on the whim of the department's head.
