This week’s objective has us “Investigating the interrelationship between policy decisions and evidence-based practice (PO 3).” More and more, we see nursing moving toward a standard of evidence-based research and practice. In my experience, the push toward evidence-based research and practice has become multidisciplinary. Even the President has mentioned ‘science-based’ programs in many of his speeches related to health care policy. I think we all can conceptually appreciate the value of practice, policy, and programs that are proven to be effective; however, there are a number of potential barriers to consider when presenting research data to policy makers. This week we will be looking to meet the course objectives by comparing and contrasting the four models of public policymaking. Additionally, we will also examine the purpose and rationales for using both the incremental and pilot approaches to policy implementation. Please answer the discussion question above, and share the variety of sources of evidence-based research that you will utilize in your policy priority. Share your rationale for your choices of evidence and why it supports your policy priority. **Policy priority is mandatory nurse-patient staffing ratio. Please scholarly references. Consider mandatory nurse-to-patient staffing ratio policy priority. How can you use evidence-based research to demonstrate the relationship of nursing practice to outcomes in mandatory nurse-to-patient staffing ratio?
