Comparison

nurse and patient

The third part of formulating the question looks at the comparison of the intervention you just described to another intervention.

In our first example, the diploma preparation of nurses is being compared to the baccalaureate preparation of nurses.

In our second example, it must be noted that some interventions do not have comparisons. So, for the administration of oral sucrose for pediatric pain management the comparison is made to the standard of care, which is no treatment.

And in the third example, the combined nurse and cardiovascular DVD approach for discharge teaching is being compared to the nurse led discharge teaching approach.

Questions to ask

  • Compared to what? Better or worse than no intervention at all or than another intervention?
  • Ask, "What is the main alternative to compare with the intervention?"
