Developing an EBP question with the PICO method

The single most useful thing to understand here is that a topic and a question are not the same object, and this assignment wants the second. Falls in older adults is a topic; whether hourly rounding reduces fall rates among hospitalised adults over sixty-five compared with usual observation over a three-month admission period is a question. The difference is that a question specifies what would count as an answer, which is exactly what makes it searchable, and what makes every later stage of your project possible rather than guesswork. Work each PICO element deliberately rather than filling in a template. The population needs enough specificity to be findable but not so much that no study has ever examined it; the intervention must be a nursing practice intervention, which the brief states explicitly and which rules out medical and pharmacological interventions however clinically interesting they are.

The comparison element is where most questions quietly fail. Comparing an intervention with nothing is rarely honest, because the alternative is almost never nothing — it is current practice, whatever that happens to be on your unit, and naming it forces you to describe what actually happens now. The outcome has to be measurable and attributable, which is a harder test than it sounds: patient satisfaction is measurable but attributing a change in it to one nursing intervention is difficult, while a fall rate per thousand patient days is both. The timeframe should be long enough for the outcome to occur and short enough to complete. Finally, take the instruction about noting difficulties seriously — a post that says the comparison was the hardest element and explains why gives your colleagues something to respond to, which is what the forum is for. A post that presents a finished question with no visible working gives your colleagues nothing to help with.
