Aim To consider evidence surrounding the emerging role of nurse practitioners in Australia with a particular focus on the provision of healthcare to older people. Methods Methods used included keyword, electronic database and bibliographic searches of international literature, as well as review of prominent policy reports in relation to aged care and advanced nursing roles. Results This paper reports on evidence from systematic reviews and international studies that show that nurse practitioners improve healthcare outcomes, particularly for hard to service populations. It also maps out the limited Australian evidence on the impact of nurse practitioners’ care in aged care settings. Conclusions If Australia is to meet the health needs of its ageing population, more evidence on the effectiveness, economic viability and sustainability of models of care, including those utilising nurse practitioners, is required. What is known about the topic? Australia, like many industrialised countries, faces unprecedented challenges in the provision of health services to an ageing population. Attempts to respond to these challenges have resulted in changing models of healthcare and shifting professional boundaries, including the development of advance practice roles for nurses. One such role is that of the nurse practitioner. There is international evidence that nurse practitioners provide high-quality healthcare. Despite being established in the United States for nearly 50 years, nurse practitioners are a relatively recent addition to the Australian health workforce. What does this paper add? This paper positions a current Australian evaluation of nurse practitioners in aged care against the background of the development of the role of nurse practitioners internationally, evidence for the effectiveness of the role, and evidence for nurse practitioners in aged care. Recent legislative changes in Australia now mean that private nurse practitioner roles can be fully implemented and hence evaluated. In the face of the increasing demands of an ageing population, the paper highlights limitations in current Australian evidence for nurse practitioners in aged care and identifies the importance of a national evaluation to begin to address these limitations. What are the implications for practitioners? The success of future healthcare planning and policy depends on implementing effective initiatives to address the needs of older Australians. Mapping the terrain of contemporary evidence for nurse practitioners highlights the need for more research into nurse practitioner roles and their effectiveness across Australia. Understanding the boundaries and limitations to current evidence is relevant for all involved with health service planning and delivery.
