This review has highlighted important aspects of physician-nurse collaboration that could be addressed by future research studies. These include: developing a comprehensive instrument to assess collaboration in greater depth; conducting rigorous intervention studies to evaluate the effectiveness of improvement strategies for physician-nurse collaboration; and examining the role of senior physicians and nurses in facilitating collaboration among junior physicians and nurses. Other implications include inter-professional education to empower nurses in making clinical decisions and putting in place policies to resolve workplace issues.

Aims To explore registered nurses' perceptions towards the role of advanced practice nurses and to examine registered nurses' interests in becoming advanced practice nurses. Background Globally, the development and implementation of advanced practice nurses have been deemed propitious. Advanced practice nurses are recruited and developed from the current pool of registered nurses. Empirical research is needed to inform practice on ensuring the sustainability of the advanced practice nurse workforce through the recruitment and development of the current population of registered nurses. Methods A nationwide cross‐sectional online survey was conducted in Singapore. Registered nurses from all public health care institutions were surveyed. Results Respondents (n = 1,025) displayed optimism and acceptance towards advanced practice nurses. However, only 30.7% hoped to become advanced practice nurses. Nursing leaders were reported to have a low success rate in identifying registered nurses who were both suitable and interested in the advanced practice nurse role. Conclusions Registered nurses' positive perspectives towards the role of advanced practice nurses do not translate into interests in the role. The study offers pragmatic applicability in ensuring the sustainability of the advanced practice nurse workforce. Implications for Nursing Management Advanced practice nurse‐specific residency programmes for pre‐master registered nurses may be facilitative to retaining and recruiting registered nurses for the advanced practice nurse workforce.
