Walden NURS 6500 Capstone Literature Review Guide

How to Research, Organize, and Write a High-Quality Evidence-Based Literature Review

The NURS 6500 Evidence-Based Practice (EBP) course at Walden University requires students to complete a literature review that supports their PICOT question, informs their capstone proposal, and establishes the evidence behind their nursing intervention.

This guide covers everything you need to create a scholarly, systematic, APA-formatted literature review that meets Walden’s graduate nursing expectations.

✅ 1. Understand the Purpose of the NURS 6500 Literature Review

Your literature review should:

• Provide background and context for your clinical problem

• Analyze current, credible, peer-reviewed evidence

• Summarize what is known, identify gaps, and show why your PICOT matters

• Support an evidence-based intervention for your capstone

Goal: Demonstrate that your problem is real, researched, and solvable with EBP.

🧩 2. Start With a Strong PICOT Question

Walden requires students to form a PICOT question before conducting the review:

• P – Patient/Population

• I – Intervention

• C – Comparison

• O – Outcome

• T – Time

Well-designed PICOT = focused search + stronger evidence base.

Example:
In adults with hypertension (P), does daily home blood pressure monitoring (I), compared to usual clinic monitoring (C), improve BP control (O) over 12 weeks (T)?

🔍 3. Use Graduate-Level Search Strategies

Search in multiple databases using Boolean operators, keywords, and subject headings.

Walden-recommended databases:

• CINAHL Plus

• PubMed / MEDLINE

• Nursing & Allied Health (ProQuest)

• Cochrane Library

• Joanna Briggs Institute (JBI)

Search tips:

• Combine keywords and MeSH terms

• Use filters: 5 years, peer-reviewed, clinical trials, systematic reviews

• Track articles in a spreadsheet (Walden encourages evidence tables)

• Download full PDFs for citation management

🧠 4. Choose High-Quality Sources

Walden stresses strong levels of evidence, such as:

• Systematic reviews

• Meta-analyses

• Randomized controlled trials (RCTs)

• Cohort studies

• Evidence-based guidelines (AHRQ, CDC, AACN, USPSTF)

Avoid: opinion pieces, blogs, editorials, non-scholarly websites, outdated sources.

🧩 5. Organize Your Literature Effectively

Use themes—not article-by-article summaries.

❗ Walden expects synthesis, not description.

Common organization methods:

• Thematic (most recommended)

• Chronological

• Methodological

Example themes for hypertension PICOT:

• Self-monitoring interventions

• Patient education strategies

• Technology-based adherence methods

• Barriers to BP control

✍️ 6. Write a Scholarly, Integrated Review

Your review should flow like a story of the evidence, synthesizing key patterns.

Include:

• Introduction (problem + purpose + PICOT)

• Themes/findings from the literature

• Methodological strengths/limitations

• Gaps in the evidence

• Implications for practice

Avoid:

• Listing each article separately

• Overly long summaries

• Unsupported opinions

Synthesis example:

❌ Study A found X. Study B found Y.
✔️ Across multiple studies (A, B, and D), home monitoring consistently improved systolic BP by 5–10 mmHg, particularly when combined with nurse-led coaching.

📊 7. Build Your Evidence Table (Required by Walden)

The evidence table helps you:

• Compare article designs

• Evaluate strength/quality

• Track outcomes

• Support claims in your narrative

Typical columns:

• Author/year

• Purpose

• Setting/sample

• Method/design

• Key findings

• Level of evidence

• Limitations

Walden faculty frequently emphasize that students must include this table for a well-evidenced project.

🧮 8. Evaluate the Strength of Evidence

Use Walden-friendly hierarchies (Melnyk & Fineout-Overholt or JBI).

Be sure to discuss:

• Sample sizes

• Study design

• Validity and reliability

• Bias

• Generalizability

🧾 9. Master APA 7 for NURS 6500

Walden is strict about APA 7. Key areas:

• Proper Level 1–3 headings

• In-text citations with DOIs

• Reference page formatting

• Use of past tense for research summaries

• Paraphrasing, not quoting, whenever possible

• Correct table and figure formatting

🎯 10. Connect the Review to Your Capstone Proposal

Your literature review must clearly support:

• Your problem statement

• Your intervention

• Your expected outcomes

• Your practice recommendations

End the review by summarizing:

• What is known

• What remains unclear

• Why your proposed project is needed
