Research is a major force in nursing, and the evidence that generate from research is changing practice, education and health policy. Our aim in developing this research book. Understanding and practice nursing research is to create an excitement about research in under and post graduate students. The book emphasizes the importance of baccalaureate-educated nurses being able to read, critique, and synthesis research. So the evidence can be used to make changes in practice. A major goal of professional nursing and health care is the delivery of evidence based care. By making nursing research an integrated part of baccalaureate education, we hope to facilitate the movement of research into the mainstream of nursing. We also hope this book increase student awareness and understanding of the knowledge that has been generated through nursing research and that this knowledge is relevant to their practice. Only through research can nursing truly be recognized as a profession with documented effective outcomes for the patient, family, nurse provider and health care system.
