Johns Hopkins Nursing Evidence-Based Practice Thrid Edition: Model and Guidelines

3 The Johns Hopkins Nursing Evidence-Based Practice Model and Process Overview 39

Evaluation: Progress toward attainment of outcomes. Includes conducting a systematic,

ongoing, and criterion-based evaluation of the goals and outcomes in relation to the

structures, processes, and timeline prescribed by the plan.

Traditionally, nurses have based their practice on policies, protocols, and procedures
that may be unsubstantiated by evidence (Melnyk et al., 2009). However, the use
of an evidence-based approach is now an expectation, a standard for the nursing
profession, and often a regulatory requirement. For example, healthcare organizations
are responding to national healthcare reform by standardizing practices based on
evidence in order to reduce inconsistencies in care, and to improve patient safety and
quality while reducing healthcare costs (Warren et al., 2016). Evidence-based practice
is a prominent aspect of the New Knowledge, Innovations & Improvement component
in the Magnet Model (see Figure 3.2). Organizations aspiring to Magnet recognition
must show continued growth and expansion of EBP activities, including critical
analysis of outcomes and the demonstration of excellence in care delivery (Ingersoll,
Witzel, Berry, & Qualls, 2010).
