PICO question help

[jessicarose]

Hello! I am in an RN to BSN program and on my last capstone course!

We need to come up with a PICO question for a evidence based research paper. I have been trying to think of questions for hours and trying to look up articles so that I won't make up a question and then have no evidence to go off of. Please give me your feedback, I would greatly appreciate any constructive criticism, re-wording, or ANY suggestions!!

Here are a couple of options:

-In adult patients diagnosed with congestive heart failure, what is the effectiveness of salt restriction compared to fluid restriction on decreasing fluid overload/CHF exacerbations?

-What is the effectiveness of wearing compression stockings, compared to not wearing compression stockings, on decreasing post-op DVT's in adult patients after orthopedic surgery?

Either of those are good, but I think you need to further define 'effectiveness'. You need a specific measure of effectiveness- rate of DVT for the compression one or weight gain or readmission for the CHF one. KWIM?
