Evidence-Based Models

Discuss two evidence-based models and describe how they are similar or different. Create and share with your classmates in the discussion forum a patient/clinical situation using the PICOT method that provides a roadmap for the clinical question. How does EBP support interprofessional collaboration?


Evidence-Based Models

Evidence-based practice (EBP) is crucial in healthcare decision-making as it guarantees clinical interventions are based on the most reliable data. The Iowa Model and the ACE Star Model of Knowledge Transformation are two well-known models based on EBP. Although they have distinct approaches, both models have the shared objective of incorporating research findings into clinical decision-making.

The Iowa Model prioritizes the translation of research findings into practical application via structured procedures. The process consists of seven phases, which encompass problem identification, critical assessment, and execution. This methodology is especially valuable for tackling intricate healthcare problems, as it encourages a systematic approach to utilizing evidence (Duff et al., 2020). The ACE Star Model emphasizes the process of knowledge transformation, which encompasses five distinct stages – awareness, familiarity, adoption, adaptation, and integration (Brunt & Morris, 2023). This concept emphasizes the significance of incorporating novel knowledge into current procedures, guaranteeing enduring enhancements in patient outcomes. Although both approaches prioritize evidence-based decision-making, they diverge in terms of their emphasis. The Iowa Model offers a systematic method for dealing with clinical problems, whereas the ACE Star Model emphasizes the ongoing process of transforming knowledge.

EBP and Interprofessional Collaboration

EBP offers healthcare professionals a shared language and framework, which promotes interprofessional collaboration. It promotes communication between various fields and guarantees that the best available data is used to guide choices. Abu-Baker et al. (2021) assert that by utilizing the skills and knowledge of multiple healthcare experts, this collaborative approach improves patient care and eventually yields better results.
