8 A typical search How does aspirin compare with paracetamol for delivering pain relief from headaches?

9 As we’re looking for the answer to a clinical query the PICO acronym may help: P the patient or population you’re considering I the intervention. The thing that is being done to treat or care for your patient C the comparison. This may be a comparison with other interventions, or the sort of research design that will best answer your question. Sometimes, there won’t be a comparison. O the outcome. What (you hope) the intervention will do to your patient

10 In this case Patients: suffering from headaches Intervention: aspirin Comparison: paracetamol Outcome: pain relief

11 Alternative terms Some terms may be described in different words. Drug names in particular commonly have both brand and generic names. In this case paracetamol’s generic name is acetaminophen.

12 Word endings Many words can end with a variety of suffixes. Alternative endings for the word nurse include nursing, nurses, nursed. Headache may appear in some references as headaches. Typing the word headache* allows you to search for all possible word endings simultaneously.
