This is the topic for my PICO question:
Advantages/Disadvantages of negative pressure wound therapy (or other types of therapy) or various treatments on wound healing
This is what I have so far:
In patients with pressure ulcers (p) what is the effect of pressure wound therapy (I) as compared with_______ (c) on wound healing (o)
What would I put for the C? Do I just choose a random type of wound healing therapy to compare it to? I think I have to be more specific than just "various treatments"
