CLABSI chlorhexidine baths literature review guide

The requirement list contains one instruction that separates passing from strong work: include a critical assessment of the sources, and do not simply include a summary of what you have read. That single line rules out the article-by-article structure most students default to, where each paragraph reports one study's methods and findings in turn. Critical assessment means judging each study — its design and evidence level, its sample size and population, whether its outcome measure matches yours, what its limitations do to its conclusions — and then organizing the review by what the literature collectively says rather than by who published it. The instruction to organize in logical sections points the same direction: sections by theme, such as efficacy evidence, safety in neonates, implementation variables, and gaps, each drawing on multiple sources at once.

The PICOT question is the review's spine and every source has to be measured against it, so read its elements deliberately. The population is neonatal patients with a central line, which is the tightest constraint in the question and the one most likely to trip your search: chlorhexidine bathing has a large adult ICU literature that is not directly transferable, because neonatal skin absorption, gestational-age-dependent barrier function, and reported dermal reactions make safety a live question rather than a settled one. The intervention is chlorhexidine bathing against no bathing, the outcome is infection rate, and the timeframe is the first 60 days after line placement. When a study you want to cite is adult-population or uses a different outcome such as colonization rather than bloodstream infection, you can still use it — but state the relevance explicitly, which the requirements ask you to do for every source, and be honest that its transferability is limited.

The remaining requirements shape the frame. An overview of the literature belongs early and should characterize the state of the evidence rather than preview your paragraphs — how much exists, what designs dominate, and where the neonatal evidence is thin compared to the adult base. Unbiased presentation means reporting studies that found no benefit or found harm with the same care as supportive ones, which in this topic is unavoidable because the neonatal safety literature is genuinely mixed. The introduction and conclusion both have to carry the PICOT question explicitly, and the conclusion must end with further questions for research — the honest ones follow from your own critical assessment rather than from convention: gestational-age thresholds, concentration and product formulation, and long-term outcomes are the gaps this literature actually leaves. Hold to six or more scholarly sources, 5-6 pages, and proper APA formatting throughout.
