This systematic review demonstrates the beneficial effects of transitional support strategies for newly qualified nurses from the perspective of the new nurse and their employer. The overall impact of support strategies appears positive, irrespective of the type of support provided. This may suggest that it is the organisations' focus on new graduate nurses that is important, rather than simply leaving them to acclimatise to their new role themselves. Future research should involve well designed randomised controlled trials with larger sample sizes, using more objective and reliable outcome measures.
