Nursing Research: Introduction & Need
Comprehensive Study Notes for Nursing Students
Nursing research1. Introduction to Nursing Research
Nursing research refers to the scientific process that aims to generate new knowledge or validate existing knowledge that directly and indirectly influences nursing practice. It is a systematic inquiry designed to develop trustworthy evidence to guide clinical practice, enhance patient outcomes, and improve health care systems.
Did you know?
Nursing research was pioneered by Florence Nightingale during the Crimean War, where systematic collection and analysis of patient data led to significant reduction in mortality rates.

2. Definitions of Nursing Research
- Polit & Beck (2021): “Nursing research is a systematic inquiry specifically designed to develop knowledge about issues of importance to nurses, nursing practice, and the profession.”
- ICN (International Council of Nurses): “Nursing research is the systematic investigation to validate and refine existing knowledge and develop new knowledge that directly and indirectly affects nursing practice.”
- Florence Nightingale: “The ultimate goal of nursing research is to improve the care of patients.”
3. Characteristics of Nursing Research
- Systematic: Follows organized steps using scientific methods.
- Evidence-based: Generates and uses reliable evidence to support nursing interventions.
- Patient-Centered: Focuses on improving patient care, outcomes, and health system processes.
- Ethical: Adheres to ethical principles, ensuring respect, integrity, and confidentiality.
- Goal-Oriented: Aims to solve clinical problems and advance nursing science.
- Innovative: Encourages creativity and exploration of new approaches for better practice.
4. Need for Nursing Research
- Evidence-Based Practice (EBP): Modern nursing relies on scientific evidence to make clinical decisions. Research equips nurses with data and outcomes to support best practices.
- Advancing Nursing Science: Research generates new knowledge, refines concepts, and develops theories specific to nursing and health care.
- Quality Improvement: Continuous improvements in patient safety, satisfaction, and clinical outcomes stem from research-driven practice changes.
- Professional Autonomy: Enables nurses to contribute to healthcare policy, advocate for patient care, and assert the nursing profession on the global stage.
- Respond to Changing Health Trends: Research helps nurses adapt to new diseases, health technologies, and evolving health needs.
- Education & Curriculum Development: Research updates and improves nursing education and skills training.
- Resource Optimization: Research helps maximize resource use, reduce costs, and eliminate ineffective care.
- Policy Formulation: Evidence from research is used in developing health policies at institutional, national, and global levels.
5. Importance & Impact of Nursing Research
| Area | How Nursing Research Makes an Impact |
|---|---|
| Clinical Practice | Guides evidence-based interventions, leads to safer and more effective care for patients. |

Introduction to the Scientific Method
Conducting high-quality research is fundamental to evidence-based nursing practice. The scientific method is an organized, logical process used to investigate questions, solve problems, and generate new knowledge. By following this method, nurses ensure their practice is grounded in reliable evidence.
Key Point: The scientific method provides a systematic and objective approach for research in nursing science.
Steps of the Scientific Method
- Identifying the Problem or Question:
Start by recognizing an area of uncertainty, a clinical dilemma, or a question based on patient care or nursing practice.
Example: “Does repositioning patients every 2 hours decrease the incidence of pressure ulcers?” - Review of Literature:
Examine existing studies and reports to gather background information, identify research gaps, and avoid duplication. - Formulating Hypothesis:
State a clear and testable prediction based on current evidence or theoretical framework.
E.g., “Frequent repositioning reduces pressure ulcer risk among immobile patients.” - Research Design/Planning:
Decide how to answer the research question – select the study type (qualitative/quantitative/mixed), sample, tools, and procedure. - Data Collection:
Systematically gather information via surveys, interviews, clinical observations, or experiments according to your plan. - Data Analysis:
Apply statistical or thematic techniques to process and summarize the collected data effectively. - Interpretation & Conclusion:
Discuss what the results mean, relate to hypothesis, and address implications for practice. - Communication of Results:
Share findings through presentations, journal publications, bedside reports, or policy changes to inform practice.

Characteristics of Good Research
Not all research is created equal. Good research is guided by certain essential characteristics that ensure its trustworthiness and value to nursing science.
| Characteristic | Description |
|---|---|
| Systematic | Follows an organized, stepwise process; avoids arbitrary decisions. |
| Logical | Based on sound reasoning; derives conclusions rationally. |
| Empirical | Grounded in observable, measurable evidence and data. |
| Replicable | Can be repeated by others with the same results, ensuring reliability. |
| Controlled | Minimizes external influences (bias, confounding variables) for accuracy. |
| Objective | Avoids personal bias; results are based on facts, not opinions. |
| Generalizable | Findings can be applied beyond the specific group studied. |
| Ethical | Protects participants’ rights, privacy, and welfare; meets ethical standards. |
