Nurses' ability to apply evidence effectively in practice is a critical factor in delivering high-quality patient care. Evidence-based practice (EBP) is recognised as the gold standard for the delivery of safe and effective person-centred care. However, decades following its inception, nurses continue to encounter difficulties in implementing EBP and, although models for its implementation offer stepwise approaches, factors, such as the context of care and its mechanistic nature, act as barriers to effective and consistent implementation. It is, therefore, imperative to find a solution to the way evidence is applied in practice. Evidence-informed practice (EIP) has been mooted as an alternative to EBP, prompting debate as to which approach better enables the transfer of evidence into practice. Although there are several EBP models and educational interventions, research on the concept of EIP is limited. This article seeks to clarify the concept of EIP and provide an integrated systems-based model of EIP for the application of evidence in clinical nursing practice, by presenting the systems and processes of the EIP model. Two scenarios are used to demonstrate the factors and elements of the EIP model and define how it facilitates the application of evidence to practice. The EIP model provides a framework to deliver clinically effective care, and the ability to justify the processes used and the service provided by referring to reliable evidence.
