NRS-445 Literature Review
The NRS-445 literature review takes the four articles you laid out in your Literature Evaluation Table and turns them into something more: a synthesized review organized around themes that answer your PICOT. The single thing that separates a strong review from a weak one is synthesis versus summary; and it’s where most students lose points. This guide shows you how to find your themes, structure the review, and weave your studies together, so you can write your own with confidence.
How to use this guide: This teaches you how to synthesize the evidence you gathered, using your own articles and PICOT. That synthesis skill is the heart of evidence-based practice — and the capstone will ask for it again.
What the assignment asks for
Building on your Literature Evaluation Table, you write a literature review that pulls your studies together into a coherent narrative organized by theme, evaluates the overall body of evidence, and points toward the practice change your PICOT proposes. It’s the bridge between gathering evidence and proposing a solution — and it feeds directly into your final EBP proposal.
The one idea that matters most: synthesis vs. summary
This is the whole assignment in a nutshell.
A summary walks through your articles one at a time: “Article 1 found… Article 2 found… Article 3 found…” Each study sits in its own paragraph, isolated. It reads like a list. This is the most common mistake, and it caps your grade no matter how well-written each paragraph is.
A synthesis organizes by theme instead of by article. You identify the ideas that run across your studies, then write about each theme by weaving together what multiple studies say about it. The articles serve the themes, not the other way around.
Here’s the shift in one line. Instead of “Smith (2021) found hourly rounding reduced falls. Jones (2022) also found rounding reduced falls,” you write: “Multiple studies associate structured hourly rounding with reduced fall rates (Smith, 2021; Jones, 2022), with one noting an added benefit to patient satisfaction (Lee, 2023).” Same sources — but now they’re integrated around an idea.
How to find your themes
- Lay your four articles side by side — your Literature Evaluation Table is built for exactly this.
- Look for patterns across the findings. What do two or more studies agree on? Where do they disagree? What keeps coming up?
- Name two to four themes. Each theme is a recurring idea relevant to your PICOT (e.g., “effectiveness of the intervention,” “barriers to implementation,” “impact on a secondary outcome”).
- Map each article to the themes it speaks to. Most articles will touch more than one — that’s good, because it means you can weave them.
If a study doesn’t connect to any theme tied to your PICOT, it probably doesn’t belong in your review.
How to structure the review
- Introduction — restate your PICOT and why the problem matters; preview your themes.
- Body, organized by theme — one section per theme, each integrating what multiple studies say. Use transitions that compare and contrast (“consistent with,” “in contrast,” “however”).
- Synthesis of the evidence and gaps — weigh the overall strength of the body of evidence and note what’s still unknown.
- Conclusion — connect the synthesized evidence to the practice change your PICOT proposes, setting up your EBP proposal.
The test of a good structure: if someone reads your section headings and they’re themes rather than article titles, you’re synthesizing.
Common mistakes that cost points
- Article-by-article organization — the summary trap; reorganize by theme.
- No clear themes — paragraphs that don’t build toward recurring ideas.
- No transitions — studies dropped next to each other without showing how they relate.
- Quote-dumping — paraphrase and integrate instead of stacking quotations.
- Losing the PICOT — every theme should connect back to your clinical question.
- No evaluation — a review weighs the evidence; it doesn’t just report it.
- APA slips — in-text citations on every borrowed idea, matched to your reference list.
How this connects to the rest of NRS-445 — and your capstone
Your review is built from your Literature Evaluation Table, which in turn came from your PICOT question — so if either of those is shaky, fix it first. Once your review is done, it becomes the evidence backbone of your final EBP proposal.
It also carries forward. The NRS-465 capstone asks for a literature review built the same way, so strong synthesis here on a capstone-worthy problem pays off twice. See how it’s applied in the capstone in the NRS-465 literature review guide.

Frequently asked questions
What is the difference between a literature review and a summary? A summary describes each article one at a time. A literature review synthesizes — it organizes by theme and weaves multiple studies together around each idea, connecting them to your PICOT.
How do I organize an NRS-445 literature review? By theme, not by article: an introduction with your PICOT, a body section for each recurring theme that integrates several studies, a synthesis of the evidence and gaps, and a conclusion pointing toward your practice change.
How many themes should I have? Usually two to four recurring ideas drawn from across your four articles and tied to your PICOT.
Which articles do I use? The same primary research articles from your Literature Evaluation Table, provided they connect to your themes and PICOT.
How does this connect to the capstone? The NRS-465 capstone uses a literature review built the same way, so strong synthesis here on a capstone-worthy problem gives you a head start.
