Research or Evidence-Based Practice? Deciding What Chlorhexidine Bathing on an Oncology Unit Actually Needs

Composite unit and cases written for a model post. No real patient or hospital is described.
Initial Post
Last quarter our composite 30-bed oncology unit had two central line-associated bloodstream infections, both in patients receiving chemotherapy through implanted ports. At a staff meeting, a colleague proposed that we "do a study" of daily chlorhexidine bathing. I want to use that proposal to work through the difference between research and evidence-based practice, because the word study may be leading us in the wrong direction.
Research is systematic inquiry designed to produce new, generalizable knowledge, usually with a formal protocol and review board oversight. Evidence-based practice brings three things together when a care decision is made: the strongest evidence that already exists, the clinician's own expertise, and what the patient values and prefers (Sackett et al., 1996; Melnyk & Fineout-Overholt, 2023). The first creates evidence; the second uses it.
Applied to our unit, the distinction is fairly clear. Chlorhexidine bathing has already been tested in large trials, including a cluster crossover trial across intensive care units and a large trial on general medical and surgical wards, so our task is to appraise and apply that evidence, not to repeat it on thirty beds. A local project would be evidence-based practice: find the evidence, judge how well it fits our patients, adapt it and measure what happens. Patient preference matters here too. Some of our patients refuse a cloth bath on days when nausea is severe, and any practice change has to account for that rather than treat it as noncompliance.
Research would start where the evidence seems to run out. Most trials studied inpatients bathed daily by staff. Many of our patients have ports and go home between infusion cycles, bathing themselves in the shower. I have not searched yet, but the literature on bathing between outpatient infusions seems thin, and that gap, not the inpatient question, is where new inquiry might belong. How would you phrase the problem so that a search could test whether that gap is real?

You described your fall-prevention audit as research because it collects numbers. I wonder whether it is closer to quality improvement, since it measures your own unit's performance against a known standard rather than testing something new. Would your hospital's review board see it that way?

Your point about staff expertise is well taken. One source you might add is the Johns Hopkins model, which builds a step for judging whether evidence fits your setting before it is applied. That step might answer the question you raised about whether ICU findings transfer to your step-down unit.

How this MN504 Unit 1 example is structured
The argument moves from case to rule and back. Naming the worry first keeps the definitions from floating free; each definition is then tested on the bathing plan rather than left as a glossary entry. The post treats the existence of prior trials as the deciding fact: when a question has been studied well, the work is appraisal and application, and repeating the trial on thirty beds would add little. Patient preference earns its own sentence, since some patients on the unit refuse a cloth bath during nausea, and a practice decision has to account for that. The gap paragraph is careful in its wording, saying the literature seems thin rather than empty, because no search has been run yet. A closing question about how to phrase the problem hands the thread forward to the question-building work that often comes next.

MN504 Unit 1 questions, answered
Is an evidence-based practice project the same as research?
No, though the two share tools. Research sets out to create knowledge that holds beyond one place, which is why it normally goes through a review board. An evidence-based practice project asks whether existing findings should change care in a particular setting, weighed alongside clinical judgment and what patients want. Many organizations still ask for a formal determination before an EBP project starts.
What if my topic seems to have no research at all?
Treat that as a finding to check rather than a conclusion. Topics often look unstudied because the search used everyday words instead of subject headings, or searched one database. If a careful search still returns nothing, the post can say so and note that the question sits closer to research than to practice, which is exactly the boundary this opening unit tends to explore.
Can the sample use a topic from my own unit?
Yes, and it reads better that way. Give the setting, the problem that caught your attention and anything you already know about the literature, and the post is built around that case. Details stay general enough that no patient or colleague can be identified, and the length and number of sources follow whatever your prompt sets.
