Delegates called for pressure to be put on hospitals and the government to cut the number of needlestick injuries suffered annually by NHS staff.
The motion urged the Healthcare Commission to provide accurate data on compliance with parts of its hygiene code that dealt with sharps, so trusts failing to take the issue seriously could be named and shamed.
It also called for this part of the code to be extended to apply to the whole of the UK, not just England.
A motion also said European legislation should be improved and safer, retractable needles should be used across the NHS.
Hugh McDyer, Bro Morgannwg health branch, said: ‘We must reduce the risk.’
