Have you ever sat down to brainstorm a nursing dissertation topic, only to feel completely stuck? You flip through journal articles, review textbooks, and scroll through endless publications, but nothing feels “new.” That’s where the magic of finding a research gap in nursing comes in.
A research gap isn’t just an academic buzzword, it’s an opportunity. It’s that missing piece in current knowledge that, once discovered, can shape the future of nursing practice, improve patient care, or even shift healthcare policy. For nursing students, researchers, and practitioners, learning how to identify a research gap in nursing studies is both a skill and an art.
But here’s the good news: spotting research gaps doesn’t have to feel hard. With the right strategies, curiosity, and a bit of creativity, you can turn frustration into clarity and maybe even into your next big breakthrough.
Let’s start with a clear definition: what is a research gap in nursing? Simply put, a research gap (or “knowledge gap”) is an area where there’s insufficient, conflicting, or absent evidence about a particular topic that is relevant to nursing science, practice, education, or policy. It’s the “missing piece” of the puzzle.
You might be asking, why are research gaps important in nursing studies? Because they are the engine of evidence-based practice. Nursing is a profession built on the highest standards of care, and those standards must be supported by current, robust evidence.
When a research gap in nursing is successfully closed by a new study, it:
Improve patient outcomes by generating evidence where it’s currently lacking. Every time a nurse researcher addresses a knowledge gap, patients benefit from more informed care decisions.
Advance nursing practice through evidence-based innovations. The gap between research and practice, often called the evidence-based practice gap, represents one of the most critical challenges in modern healthcare.
Shape healthcare policy by providing data decision-makers need. Research that fills important gaps often influences guidelines, protocols, and regulations.
Contribute to nursing theory by testing, refining, or challenging existing frameworks. Theoretical gaps can be just as important as practical ones.
Understanding this importance transforms gap identification from a tedious academic exercise into a purposeful contribution to your profession.

Once you have a general area say, “post-operative pain management in older adults” you need to drill down to a specific, manageable gap. This process transforms a broad interest into a specific, testable hypothesis. This is how to develop a research question from a gap in nursing.
The PICO (Population, Intervention, Comparison, Outcome) or PEO (Population, Exposure, Outcome) frameworks are excellent tools for focusing your broad gap into a sharp research question.
Example of Research Gap Identification for a Nursing Dissertation:
This transition from a vague topic to a clear question is the most crucial step in the research process. It ensures your study addresses a true research problem in nursing.
To avoid studying yesterday’s problems, researchers must be aware of emerging trends in nursing research. New technologies, global health crises, and shifting demographics constantly create new, urgent research gaps.
Identifying a research gap is a foundational step in conducting meaningful and impactful nursing research. It involves a systematic process of inquiry that moves beyond simple curiosity to a scholarly investigation of what is known, what is unknown, and what needs to be further explored within a specific domain of nursing practice. A well-defined research gap provides the rationale for a new study, ensuring that the work contributes original and necessary knowledge to the field.
The initial step is to delineate a broad area of professional interest grounded in your clinical experience, academic background, or passion. This broad area serves as a starting point that requires systematic narrowing to become a feasible research topic.
A thorough review of existing literature is the cornerstone of identifying a research gap. This process involves more than just reading articles; it requires a critical and organized appraisal of the current state of knowledge.
Move beyond individual studies to synthesize the literature as a whole, identifying overarching trends and notable omissions.
Research gaps frequently exist because studies have been confined to specific demographics or environments, limiting the generalizability of their findings.
A gap can be defined not only by what is studied but also by how it is studied. Methodological limitations in prior research can provide a strong rationale for a new study.
An identifiable gap is most compelling when it has clear implications for nursing practice, patient outcomes, or healthcare policy.
Insights from experienced professionals can often illuminate practical challenges and unanswered questions that are not yet apparent in published literature.
Valuable information often exists outside of traditional peer-reviewed journals. This “grey literature” can highlight research priorities and practical challenges.
Nursing is a dynamic field that is constantly influenced by broader societal, technological, and environmental shifts. These changes continuously generate new questions and research needs.
By systematically applying these steps, a researcher can move from a broad area of interest to a well-articulated, significant, and justifiable research gap that forms the foundation of a successful and impactful study.
Not all gaps are created equal. Understanding the different types helps you frame a powerful and focused research problem in nursing.
Let’s ground this discussion in concrete nursing research gap examples that illustrate different gap types:
The Gap: While numerous studies examine electronic health record (EHR) implementation, few investigate how nurses adapt their clinical reasoning processes when transitioning from paper documentation to EHR systems.
Why It Matters: Understanding this cognitive shift could inform training programs and system design.
Gap Type: Qualitative, process-oriented gap in nursing education and professional development.
The Gap: Most pediatric pain assessment research focuses on verbal children, leaving non-verbal children with autism spectrum disorder underrepresented in evidence about effective pain identification methods.
Why It Matters: Inadequate pain assessment leads to under-treatment and suffering.
Gap Type: Population-specific gap with direct clinical implications.
The Gap: Research demonstrates that nurse burnout contributes to turnover, but longitudinal studies tracking the effectiveness of organizational interventions over time are scarce.
Why It Matters: Without long-term data, healthcare systems can’t evaluate whether their retention strategies actually work.
Gap Type: Methodological gap requiring different research designs.
Nursing education presents unique opportunities for gap identification. Here are examples of research gaps in nursing education worth considering:
Simulation fidelity versus learning outcomes: Does higher-fidelity simulation always produce better learning, or is there a point of diminishing returns?
Clinical placement alternatives: With traditional clinical sites becoming saturated, how effective are alternative placement models like dedicated education units or virtual reality simulations?
Transition to practice programs: Which specific elements of nurse residency programs most effectively reduce new graduate turnover and improve competency?
Interprofessional education effectiveness: Most studies measure attitudes toward collaboration, but few examine whether interprofessional education translates to actual collaborative practice.
Assessment methods for clinical judgment: As nursing education shifts toward concepts like clinical judgment, how do we reliably assess this complex competency?

Finding the gap is only half the battle. Research gap identification for nursing dissertations requires transforming that gap into a focused, researchable question.
Use this framework to refine your gap into a research question:
1. Be Specific Instead of: “There’s limited research on nurse burnout” Try: “How do organizational support structures influence burnout rates among nurses working in rural critical access hospitals?”
2. Ensure Feasibility Consider your available resources, timeline, and access to participants. An ambitious gap might need to be narrowed for a master’s thesis but could work for a doctoral dissertation.
3. Confirm Significance Ask yourself: If I answer this question, will it matter? Will it change practice, inform policy, or advance theory?
4. Identify Your Variables or Phenomena Clearly articulate what you’re studying and the relationships you’re exploring.
5. Define Your Population Specify exactly who your research involves and why that population is meaningful.Turning a Research Gap into a Research Question
Once you’ve spotted a gap, the next step is shaping it into a solid question. A good nursing research question is:
Example: Instead of asking, “How do nurses support cancer patients?” narrow it down to “What are the most effective nursing interventions to reduce anxiety in breast cancer patients undergoing chemotherapy?”
This task requires writing a long-form blog article of at least 1,200 words, optimizing it for SEO with a comprehensive set of keywords, and structuring it for high readability. I’ll refine the title, create an engaging introduction, use clear headings, and incorporate the keywords naturally throughout the detailed sections.
By focusing on these areas, your research is not just filling a hole; it’s pushing the profession forward into the future. You are actively answering the question, “what are examples of research gaps in nursing practice?” with contemporary relevance.
Many students say, “But everything seems to have been studied already!” That’s not true. What usually happens is:
They only read the most popular articles instead of digging deeper.
They don’t compare methods or populations.
They’re afraid their topic won’t feel “big enough.”
So, how do you identify a research gap in nursing studies? You read widely, ask tough questions, look for underrepresented voices, and stay curious about emerging trends.
Research gaps aren’t roadblocks; they’re doorways. They’re your chance to contribute something original, meaningful, and practical to the world of nursing.
If you’re writing your dissertation, preparing a literature review, or seeking ways to improve patient care, take this as motivation: the gap you find today could be the solution that transforms tomorrow’s healthcare.
Stay curious. Stay compassionate. And never underestimate your role in shaping the future of nursing research.
