Chapter 24: Nursing Research & Evidence-Based Practice

Beginning with the historical legacy of Florence Nightingale, who pioneered the use of objective data to drive reform, it traces the journey from experiential trial-and-error methods to the modern scientific process, which validates nursing interventions through empirical evidence. Central to this discussion is the shift toward Evidence-Based Practice (EBP), a gold standard that integrates the best available research with clinical expertise and patient preferences. The text delves into the distinct methodologies of quantitative research, which utilizes objective data and controlled variables to establish causal relationships, and qualitative research, which focuses on the subjective meanings of human experiences like quality of life or spirituality. Students will learn to navigate the research process using the PICO framework (Population, Intervention, Comparison, Outcome) and understand the importance of Evidence Reports, which rank the strength of findings from high-level meta-analyses to individual case reports. Furthermore, the chapter addresses the significant impact of the Affordable Care Act and the Patient-Centered Outcomes Research Institute (PCORI) on funding and comparative effectiveness research (CER), highlighting priorities like chronic disease management and infection prevention. A major focus is placed on narrowing the research-practice gap, identifying systemic barriers such as entrenched traditions and a lack of administrative support, while proposing strategies like the Rosswurm and Larrabee Model for successful clinical implementation. Ethical considerations remain paramount, with deep dives into the Nuremberg Code, the role of Institutional Review Boards (IRBs), and the necessity of informed and process consent to protect vulnerable populations. Finally, the chapter outlines the specific research competencies expected at every educational level, from associate degree graduates assisting in data collection to doctoral-prepared nurses leading theoretical development and systemic change within the healthcare system.
