FNH 398 Assignment 1 Tips


  • Question: Do I need to use all of the PICO elements in my search?

Answer: No. Often, you will simply search for the P & I, or P & O. Depending on the amount of literature, you may find that your results are too small if you search for P, I and O.

  • Question: Can I create a very different PICO question than the one listed in the scenario?

 Answer: There is some flexibility in your PICO - e.g. your friend may be a senior citizen, or pregnant, however you PICO should be based on the general scenario that has been provided.

From the Assignment, "Using the scenario below as a guide, develop a clear question following the PICO framework. You do not need to include all of the components of the scenario in your PICO question; rather use this scenario to inspire a specific, searchable, and focused question. You can choose which age group, gender, life course stage (i.e. pregnant, breastfeeding, adult, senior) that is of interest for your hypothetical patient/population. There are more than one “correct” PICO questions that can emerge from this scenario, so keep your question clear and focused.

Scenario: : Your friend is concerned about becoming too stressed during the school year and has heard that certain micronutrient supplements, including vitamin D, B vitamins, or iron may help improve their mental wellbeing. Your friend wants to know whether they should consider taking one of these.

  • Question: What is the best truncation symbol for searching 0 to 1 character? eg. vitamin B, vitamin B1, vitamin B2....

To find 0 to 1 character e.g. vitamin B, vitamin B1, vitamin B2, etc., use the ? symbol. To find the literature on vitamin B12, you need to use two symbols e.g. vitamin b?? Do not use the truncation symbol: * e.g. vitamin b* as it will retrieve any words starting with b!
