Differences and similarities in scope of practice between registered nurses and nurse specialists in emergency care: an interview study.

No differences were seen between registered nurses' and nurse specialists' role, and professional accountability and responsibilities in the context studied here, although the level of nursing competence differed. Before and even after consensus on uniform competence standards for the different professional nurse groups is reached, management teams should invest in reviewing nurses' competence in relation to different expertise levels, and strategically recruit so that current health needs in the emergency departments can be met.
