Exercise 1 - Finding the best evidence

In conversation with someone who is expecting, you are asked for your thoughts on whether they should consider having umbilical cord blood banked after they give birth. They are wondering if it is worth the cost, and if it poses any risks to the baby. You are unfamiliar with this practice, and want to provide the best evidence possible, but you know you won't have a lot of time to look it up.

  • Using the evidence pyramid as your benchmark, what is the strongest, most relevant piece of evidence on this topic you can find?
  • What tools/search words were most helpful?

What is the 6S pyramid?

The 6S evidence pyramid above is designed to help health practitioners prioritize evidence. The higher up the pyramid your evidence falls, the more weight you should give it in your clinical decision making process. Not every topic will have evidence at all levels – use the highest level that is available. 

Currently, we do not have access to Systems level evidence at Mount Royal. The resources listed below will help you look for evidence at each of the remaining levels.

The image above is based on levels discussed in the following article:
