ACE STAR Model and John Hopkins Model are evidence-based practice (EBP) models implemented to assist nurses in converting evidence into practice because according to Gawlinski and Rutledge (2008), their use results in a systematic methodology to EBP thus preventing incomplete implementation and optimum utilization of nursing resources and time. The two models have unique strengths and limitations. For instance, ACE STAR model has a strength of focusing on the search of nursing evident that inform qualitative evidence and bedside nursing practice. Secondly, ACE STAR model concentrates on factors which impact on the espousal of innovation, a critical aspect of developing contemporary and effective preventive and nursing practices CITATION Ste04 \l 1033 (Stevens, 2004 ). The primary objective of ACE STAR Model is the transformation of knowledge. However, the limitation with the use of ACE STAR is that it is time-consuming as it involves a rigorous 5-step process from discovery research to the evaluation of process and outcomes of practice integration. On the other hand, the strengths of John Hopkins Model include the provision of tools for rating and appraising non-research and research evidence CITATION Sch12 \l 1033 (Schaffer, Sandau, & Diedrick, 2012). It is also useful in a numerous healthcare settings. The weakness of the model is its applicability on individual use only and overshadowing organizational application, unlike other EBP models.
ACE STAR Model and John Hopkins Model are similar in that they both provide practical guidelines for bedside nurses to apply in utilizing best evidence to inform their care decisions. The difference between the two models arises from the EBP stages. While John Hopkins Model comprises 2-step EBP process such as practice question development, evidence and translation, ACE STAR model utilize five stages namely discovery, evidence summary, translation, integration and evaluation CITATION Sch12 \l 1033 (Schaffer, Sandau, & Diedrick, 2012). Lastly, ACE STAR Model, emphasizes knowledge transformation for both individual and organization use, but John Hopkins Model accentuate administrative processes thus highlighting organizational use CITATION Pat17 \l 1033 (Ryan & Rodriguez, 2017).
