Evidence-based nursing: 4 years down the road.

Evidence-based practice in the nursing profession is gaining wider popularity as shown by the increasing number of nursing conferences with an evidence-based theme, journals that feature “evidence-based, best practices in healthcare”, professional nursing organisations that are developing or promoting clinical practice guidelines, and subscription to this journal by over 8000 nurses from around the world. As we begin our fifth year of production of Evidence-Based Nursing (EBN), it is useful to look back at developments that have occurred over the past 4 years. In this editorial, we will describe the involvement of our many colleagues in the production of this journal, identify the journals from which we abstract the most studies, highlight the purposes of our editorials, and update our readers about our website.
