Around 323 delegates voted in favour of the resolution, roughly 80% of respondents.
Claire Picton, a member of the RCN Emergency Care Association, raised the resolution and outlined how regulation of advanced nursing practice could enhance patient safety.
She said it would allow for enhanced role protection and ensure that advanced nurse practitioners carry out set core competencies.
Ms Picton also highlighted it has the potential to enhance clinical governance, reduce the risk of adverse incidents and make nurse career pathways more transparent.
Jenny Aston, chair of the RCN Advanced Nurse Practioner forum, said: ‘Patients have a right to know that someone calling themselves an advanced nurse practitioner has the appropriate level of education.'
But Wendy Hughes, a member of the RCN Wales Gwynedd Branch, raised concerns that advanced nursing practice regulation would create a ‘two-tier profession'.
‘And who would bear the cost of all this. Would any separate regulation come out of the pot of gold from NMC fees?,' she asked.
