Evidence Based Practice: Nursing Research

Course Description

NUR4169C – Evidence Based Practice: Nursing Research is a 3-credit upper-division nursing course on how nursing knowledge is produced, evaluated, and put into practice. It is a standard requirement in RN-to-BSN completion programs, which Florida state colleges offer widely, and it is frequently the course that most distinguishes BSN preparation from associate degree preparation.

The premise is that nursing practice should rest on evidence rather than on tradition, authority, or convenience — and that a great deal of routine practice does not. The course does not train students to conduct research; it trains them to read it competently, judge whether a finding is strong enough to change what they do, and participate in implementing change on a unit.

Content covers the research process and how nursing science is generated; evidence-based practice models — the Iowa Model, the Johns Hopkins model, and the steps common to them; asking answerable questions using the PICO framework; literature searching in CINAHL, PubMed, and the Cochrane Library; levels of evidence and the evidence hierarchy, including why systematic reviews sit at the top and expert opinion at the bottom; quantitative designs — experimental, quasi-experimental, and non-experimental, with attention to what each can and cannot establish; qualitative designs — phenomenology, grounded theory, and ethnography, and the questions they answer that trials cannot; sampling, measurement, reliability and validity; basic statistics for reading results — descriptive measures, significance, confidence intervals, and effect size; critical appraisal of published studies; research ethics — informed consent, IRB review, vulnerable populations, and the historical abuses that produced current protections; translating evidence into practice and the barriers that stop it; and dissemination.

Offered at approximately 12 Florida institutions with RN-to-BSN or prelicensure BSN programs.

• Dissemination — posters, presentations, and writing for practice audiences.
• EBP project — the applied deliverable.

Optional Topics

• Clinical practice guideline development.

Resources & Tools

• Nursing Research: Generating and Assessing Evidence for Nursing Practice (Polit & Beck), Wolters Kluwer — the standard text.
• Evidence-Based Practice in Nursing and Healthcare (Melnyk & Fineout-Overholt) — the most practice-oriented option and widely used in RN-to-BSN programs.
• Understanding Nursing Research (Grove & Gray), Elsevier.
• CINAHL — the nursing and allied health database; access is through the college library and is the single most important tool in the course.
• PubMed and the Cochrane Library — free; Cochrane systematic reviews are the top of the evidence hierarchy.
• Johns Hopkins EBP appraisal tools and CASP checklists — free structured appraisal instruments.
• The librarian — the most underused resource in this course; college librarians teach database searching directly and will meet with students.
• APA Publication Manual — nursing writes in APA style and it is graded.
• Florida Board of Nursing and ANA — scope, standards, and the code of ethics.

Career Pathways

• Registered Nurse (SOC 29-1141) with a BSN — the immediate outcome for RN-to-BSN students.
• Charge Nurse and Nurse Manager — where BSN is frequently required.
• Clinical Nurse Educator and Staff Development.
• Quality and Patient Safety roles — connects directly to HSA4383 content.
• Clinical Research Coordinator — a distinct pathway that this course opens.
• Infection Preventionist and specialty coordinator roles.
• Graduate study — MSN, DNP, or PhD; this course is the prerequisite competency for all of them.
• Nurse Practitioner and advanced practice — requiring graduate education.

Special Information

Why the BSN matters, and why this course is the reason

Associate degree preparation is heavily clinical; BSN preparation adds leadership, community health, and this — the ability to evaluate evidence. That is the substantive difference, not merely an additional credential. It matters practically because Magnet-designated hospitals and many Florida health systems prefer or require BSN preparation for hiring and advancement, and because charge nurse, management, education, and any graduate pathway assume it. Florida state colleges offer RN-to-BSN completion at comparatively low cost, and this course is usually where students find out whether they enjoy the analytical side of nursing.

⚠ Upper-division standing and program admission

The 4000-level number means upper-division coursework within a BSN program. It requires admission to that program — typically an active, unencumbered Florida RN license for RN-to-BSN students — and is not open to general enrollment. A.S. nursing graduates should note that their ADN credits transfer into the BSN under Florida's articulation arrangements, but the upper-division nursing courses must be completed in the BSN program. Verify the specific pathway with the program, since RN-to-BSN structures vary in length and delivery.

Statistics is not optional here, and most students underestimate it

Nurses frequently arrive expecting a reading course and find that appraising a study requires understanding what a p-value does and does not mean, why a confidence interval is more informative, and why a statistically significant result can be clinically trivial. That last distinction — statistical significance versus clinical significance — is the single most useful idea in the course. A 2 mmHg blood pressure reduction can be highly significant in a large trial and irrelevant at the bedside. Students who take the statistics content seriously read the literature very differently afterward.

Learn to distinguish research, EBP, and quality improvement

These are routinely confused and have different purposes, methods, and oversight requirements. Research generates new generalizable knowledge and requires IRB review. EBP applies existing evidence to a practice setting. Quality improvement tests changes in a local system to improve care there. A project's classification determines whether IRB approval is needed, which nurses encounter directly when proposing unit-level projects. Getting this wrong causes real administrative problems.

Use the librarian — database searching is a taught skill

Most students search databases the way they search the open web, and get poor results. Controlled vocabulary, Boolean logic, filters, and citation chaining are learnable in a single session with a librarian, and the difference in search quality is substantial. This is the highest-return hour available in the course.

Course numbering and configuration

The course appears as NUR4169 and NUR4169C; where the C suffix appears it generally reflects an applied evidence-based practice project component rather than a clinical laboratory schedule, so the contact hours track a standard 3-credit course. Related content appears under other NUR numbers for research and for leadership. SCNS equivalency applies to the same number at the same level, never across numbers — verify what a receiving program requires.
