Implementation of evidence–based practice in clinical practice is crucial. Nurses and midwives play a vital role in using updated evidence. Evidence-based health care practices are available for a number of conditions such as asthma, heart failure, and diabetes. However, these practices are not always implemented in care delivery, and variation in practices abound. Traditionally, patient safety research has focused on data analyses to identify patient safety issues and to demonstrate that a new practice will lead to improved quality and patient safety. Much less research attention has been paid to how to implement practices. Yet, only by putting into practice what is learned from research will care be made safer. Implementing evidence-based safety practices are difficult and need strategies that address the complexity of systems of care, individual practitioners, senior leadership, and—ultimately—changing health care cultures to be evidence-based safety practice environments.
