Evidence-based medicine (EBP), also known as evidence-based healthcare, is a method of providing care that relies on the most recent research to make clinical decisions. Over the years, several EBP models have been created to assist healthcare professionals in integrating research evidence into practice. EBP is commonly implemented in two models:
- Marita Titler, a professor at the University of Iowa and her colleagues developed this model in 1994. It is an easy-to-follow process that includes six steps: 1) problem identification, 2) evidence synthesis and analysis, 3) feasibility and impact assessment, 4) implementation planning, 5 ) implementation and 6 ) evaluation. Iowa Model emphasizes that all stakeholders should be involved in EBP, including patients, healthcare providers and administrators.
- Early 2000s, Gill Harvey, Brendan McCormack and Alison Kitson developed the PARIHS Model. The Promoting Action on Research Integration in Health Services model (PARIHS). This model highlights the importance three important elements to successful EBP Implementation: (1) Evidence, (2) Context, and (3) Facilitation. According to the PARIHS model, successful EBP implementation is dependent on three factors: the quality of evidence, context, and support for healthcare professionals. PARIHS is often used as a guide to develop interventions that promote the implementation of EBP in healthcare settings.
