The number of articles or amount of evidence needed to make a practice change is based on a combination of factors:
1. The Level and Quality of Evidence Found.
- It is a good practice to have team members evaluate the same articles/evidence separately and then compare evaluations. When there is a discrepancy you should discuss and come to a consensus as to the grade and level of the article/evidence.
- Remember that some questions will not have Level I evidence. Keep in mind the type of question you are asking will help to dictate the type of primary studies or level of evidence that may be available to answer the question.
2. The decision is also influenced by the depth of clinical knowledge/expertise of the team.
- The composition of your team is critical because the knowledge of the team may help to fill in the blanks of the evidence you have found. The team members will also be key when it comes to properly evaluate the evidence and gaining buy-in from the stakeholders on the unit or patient.
3. The willingness of Patient or Unit to Adopt of Go Along with the Practice Change.
- Important to have an interdisciplinary team and be sure you are communicating with the person or persons that the intervention will affect. Communication is key as to whether the practice change or intervention will be adopted.
