1Chapter 01: Introduction to Nursing Research and Evidence-Based Practice What is Nursing Research?Research has a purpose: to enhance the body of knowledge within a discipline. Nursing research focuses on generating new information that has a direct or indirect effect upon practice, or replicating previous research so as to confirm those earlier findings.What Is Evidence-Based Practice?Evidence-based practice (EBP) represents nursing actions that are based upon best research evidence, clinical expertise, and patient needs and preferences, all of which are valuable sources of evidence. Within health care, EBP’s goals are improved quality, enhanced safety, and cost containment. Best research evidence is a synthesis of available research in one area. It may be published as a practice or clinical guideline. It is but one of three sources for EBP.Purposes of Research in Implementing an Evidence-Based PracticeA phenomenon (pl. phenomena) is a thing, and within nursing research terminology it is an area of interest or enquiry (e.g., hypertension, hardiness, chest pain, panic episode). Nursing research examines a phenomenonin order to describe it, explain it, predict its occurrence or conditions, and control its manifestation, trajec-tory, or sequelae. Description in research is a way of sorting, classifying, and counting. When a quantitative sample is described,it is sorted into groups in terms of one or more of its variables. Then the items in each group are statistically analyzed. When a qualitative sample is described, similar items are identified and grouped, and a narrative description of the sample is written based on the data the subjects provide. Explanation is the process of assigning meaning or interpreting. If a relationship or pattern is observed in re-search data, explanation should be provided for the reasons that such a pattern or relationship exists.Prediction is, literally, stating future occurrence. Some types of research enhance the reader’s ability to predictwhat, where, or when something will occur. An example of this is correlational research examining the risk of cancer, in comparison with a variable such as tobacco use, vegetable intake, vitamin use, or heredity. Control as an outcome of nursing research refers to the clinician’s ability to do something that produces a de-sirable outcome. An example of this would be research that tests the effect of an intervention intended to im-prove client health.Historical Development of Research in NursingFlorence Nightingale is important because she was a talented, articulate, educated, well-read, widely pub-lished nurse who conducted well-designed research to improve practice. Because of her scientific inquiry and her assertive leadership, patient care and outcomes improved, establishing that research conducted by a nurse can impact client health.
