BackgroundAlthough well-established internationally, nurse practitioners (NPs) in Australian adult intensive care units (ICUs) are rare. Australian literature clearly highlights the importance of creating ICU NP roles to meet emerging demands. An ICU NP model of care at a metropolitan hospital in Sydney provides care in four core practice areas: complex case management, vascular access, tracheostomy management, and intrahospital transport of critically ill patients. The ICU NPs also provide training and assessment for ICU nurses and medical officers in these same core practice areas and can efficiently meet service gaps in crisis such as the most recent COVID-19 pandemic. ResultsThe ICU NP program described is an innovative model of care that has demonstrated potential benefits to patients and their families. Potential benefits to the healthcare system including supporting advanced practice nursing development in regional and rural Australia and in addressing future ICU workforce issues are also identified. This model of care provides a clear role and structure for the integration of NPs in the adult ICU. Research to evaluate the impact of the role is required and is underway. ConclusionsThis model is being used to develop a national adult ICU NP fellowship training program for ICU transitional NPs preparing for endorsement or endorsed NPs who require additional ICU-specific training. This immersive clinical training program combined with didactic learning modules offers a framework to support the implementation of the adult ICU NP role as well as a framework for NP fellowship programs in other specialties.
