The difference between a QI project and research for a DNP capstone lies in purpose: quality improvement improves care in one setting, while research aims to produce knowledge that applies beyond it. That purpose shapes your design, approval route and write-up.
Most DNP projects are quality improvement or evidence-based practice projects, but students often describe them in research language by mistake. This guide sets out the differences clearly and helps you classify your own project.
The Core Difference in One Line
QI asks: "How can we make care better here, using what is already known?"
Research asks: "What is true, in a way that others can generalize from?"
A DNP project usually translates existing evidence into practice and measures the local result, which is quality improvement. A PhD dissertation usually generates new, generalizable knowledge, which is research.
QI and Research Side by Side
| Dimension | QI project | Research study |
|---|---|---|
| Purpose | Improve a process or outcome in a specific setting | Create generalizable knowledge |
| Starting point | Existing evidence and a local problem | A gap in knowledge |
| Design | Iterative cycles such as Plan-Do-Study-Act | A fixed protocol set in advance |
| Changes during the project | Expected and documented | Avoided once data collection begins |
| Data | Often routine data, run charts, pre and post comparison | Often new data collected under controlled conditions |
| Typical approval | QI determination or exemption, per institution | Full IRB review of the protocol |
| Reporting guideline | SQUIRE 2.0 | Design-specific, such as CONSORT for trials or STROBE for observational studies |
No single row decides the matter. Institutions look at the whole picture, and especially at intent: what you are trying to achieve and who the findings are for.
Why the Distinction Matters
Classifying your project correctly affects nearly every later step. It decides the approval you need, how long that approval takes, what your methods section looks like and which reporting standard your final paper follows.
Getting it wrong is costly. A QI project described in research terms may be sent for full IRB review, adding weeks. A project that is really research but labeled QI can face problems later, especially if you hope to publish, because data collected without the right approval may not be usable.
The AACN frames the DNP project as practice-focused scholarship that translates evidence into practice rather than generating new knowledge. That is why most programs expect a QI or evidence-based practice design.
Questions to Classify Your Project
Work through these questions with your adviser. Several "research" answers suggest you should seek a formal determination from your IRB rather than assuming the project is QI.
| Question | Points to QI | Points to research |
|---|---|---|
| What is the main aim? | Improve local care | Answer a question for the wider field |
| Is the intervention evidence-based already? | Yes, it is being implemented | No, it is being tested |
| Will patients be randomized? | No | Yes |
| Does the project add risk beyond usual care? | No, or minimal | Yes |
| Will you change the plan as you learn? | Yes, through rapid cycles | No, the protocol is fixed |
| Who benefits from the findings? | The unit or organization | The broader scientific community |
Publishing does not by itself turn QI into research. Many QI projects are published using SQUIRE 2.0. What matters is the design and intent from the start.
Where Evidence-Based Practice Fits
Students often meet a third term alongside QI and research: evidence-based practice, or EBP. The three overlap, which is part of the confusion.
- Research generates new evidence.
- EBP finds, appraises and applies the best existing evidence to a clinical question, alongside clinical expertise and patient preferences.
- QI uses systematic methods to improve processes and outcomes in a specific setting, often by implementing an EBP change.
Many DNP projects combine EBP and QI. The student appraises evidence for an intervention (the EBP part) and then implements and measures it locally using QI methods. Models such as the Iowa Model or the Johns Hopkins EBP model guide the evidence work, while PDSA cycles guide the implementation.
QI Methods and Measures in Practice
QI methods are designed for learning in real time. A PDSA cycle plans a small change, tries it, studies the results and acts on what was learned, before the next cycle begins.
Measures are usually grouped into three types. Outcome measures show whether patients are better off, process measures show whether the change is happening as planned, and balancing measures check for unintended harm elsewhere.
Results are often displayed on run charts or statistical process control charts, which show change over time rather than a single before-and-after figure. This suits QI, because the aim is to see whether improvement is real and sustained in your setting.
Examples of Each
QI project: A DNP student implements an evidence-based bedside handover tool on a surgical unit, trains staff, and tracks handover omissions and staff satisfaction over three PDSA cycles, refining the tool after each cycle.
Research study: A PhD student randomly assigns four surgical units to either a new handover tool or standard handover and compares adverse events over six months, using a fixed protocol, to test whether the tool causes better outcomes.
Both projects focus on handover, but the first improves care on one unit using existing evidence, while the second tests a causal question to inform practice everywhere. The difference lies in purpose and design, not the topic.
How the Literature Review Differs
Both project types need a rigorous review of evidence, but the review does a slightly different job in each.
- In QI: the review shows that strong evidence already supports the intervention, so implementing it locally is justified. You appraise and synthesize the evidence, often with a model such as Johns Hopkins.
- In research: the review shows a gap in knowledge that your study will fill. It ends by identifying what is not yet known.
A QI literature review that ends by saying "more research is needed" undermines its own argument. If the evidence is not strong enough to implement, the project may need rethinking.
Writing in the Right Language
Many classification problems start with wording. Research words in a QI proposal can lead reviewers to treat it as research.
| Avoid in a QI proposal | Use instead |
|---|---|
| Research study, subjects | Quality improvement project, participants or staff |
| Hypothesis | Aim or expected improvement |
| Generalizable findings | Local improvement |
| Experimental and control groups | Pre-implementation and post-implementation data |
Language should match reality, not disguise it. If your project genuinely is research, describe it as research and seek full IRB review.
Common Mistakes to Avoid
- Assuming the project is QI without asking your institution for a determination.
- Using research terms throughout a QI proposal.
- Planning randomization or added risk while calling the project QI.
- Starting data collection before written approval.
- Reporting a QI project with a research template instead of SQUIRE 2.0.
- Ending a QI literature review with a call for more research.
When in doubt, talk to your adviser and your IRB early. A short conversation now can save a long delay later, and it gives you a written decision to cite in your proposal.

Frequently Asked Questions
Most DNP projects are quality improvement or evidence-based practice projects that translate existing evidence into practice. Your institution decides the classification.
Many institutions require a QI determination, which may confirm that full IRB review is not needed. Always follow your institution's process.
Yes. Many QI projects are published using the SQUIRE 2.0 reporting guidelines. Publication alone does not make a project research.
Purpose. QI improves care in a specific setting; research aims to produce generalizable knowledge.
Often iterative Plan-Do-Study-Act cycles, with run charts or pre and post comparisons to track change.
Randomization usually signals research. If your design involves it, seek a formal determination from your IRB.
A QI review shows the evidence is strong enough to implement. A research review identifies a gap the study will fill.
We never invent data. A writer can present and discuss results you collected in a custom section for your study and reference.
The Standards for Quality Improvement Reporting Excellence, a set of guidelines for writing up QI work. Many programs ask DNP students to structure the final paper around it.
EBP appraises and applies existing evidence to a clinical question. Many DNP projects use EBP to choose an intervention and QI methods to implement and measure it.
