Although evidence-based practice (EBP) improves health care quality, decreases costs, and empowers nurses, there is a paucity of intervention studies designed to test models of how to enhance nurses' use of EBP. Therefore, the specific aim of this study was to determine the preliminary effects of implementing the Advancing Research and Clinical practice through close Collaboration (ARCC) model on nurses' EBP beliefs, EBP implementation behaviors, group cohesion, productivity, job satisfaction, and attrition/turnover rates. A 2-group randomized controlled pilot trial was used with 46 nurses from the Visiting Nurse Service of New York. The ARCC group versus an attention control group had stronger EBP beliefs, higher EBP implementation behaviors, more group cohesion, and less attrition/turnover. Implementation of the ARCC model in health care systems may be a promising strategy for enhancing EBP and improving nurse and cost outcomes.

This article presents a new model, Evidence-Based Practice Improvement, for improving patient care. The model merges 2 extant paradigms currently used for quality improvement initiatives-evidence-based practice and practice or performance improvement. The literature expounds on the virtues of each of these approaches, yet no authors have moved beyond parallel play between them. The merged model, Evidence-Based Practice Improvement, may provide a more effective and practical approach to reach our quality goals.
