Nursing is “the diagnosis of human responsesto actual or potential health problems.” (American Nurses’ Association) What is Nursing?
Human Response Viewed From Four Perspectives Physiological regulatory responses Pathophysiological responses Experiential responses Behavioral responses
Human Response Model These perspectives are used in other disciplines; however, nursing science synthesizes them explicitly considering their linkages in clarifying human response phenomena.

Biologically-based Nursing Research Training Objectives • Apply theories and methods of the • biological sciences in the identification of problems arising from human responses to acute and chronic diseases (stressors)
OBJECTIVES continued 2. Integrate theories and methods of the basic sciences, nursing, and related theories regarding human response to acute and chronic illnesses (stressors)
OBJECTIVES continued 3. Demonstrate skill in the biologic approaches to measurement. 4. Demonstrate proficiency in design, data generation and analysis of biologically-based nursing research
Examples Of Biologic Research Neurologic impact of diabetes Nutrition and gut mobility Gender differences in cardiac function Mechanisms of wound healing
Translational Research(Bench To Bedside) Effective translation of new knowledge, mechanisms and techniques generated by advances in basic science research into new approaches for the prevention, diagnosis and treatment of disease
Translational Neuroscience Accomplishments Retinitis pigmentosa: gene therapy Parkinson’s disease: deep brain stimulation Stroke: cooling brain, TPA for clots Depression, bipolar disorder and schizophrenia: pharmacology
Magnetic Resonance Imaging (MRI) Tesla discovered the rotating magnetic field in 1882. (Invented the radio) In 1956, the “Tesla Unit” was proclaimed as unit of measurement of the strength of a magnetic field. All MRI’s are calibrated in Tesla Units. The strongest MRI is 9.4 Tesla units.
Molecular Imaging Measuring neurotransmitters GABA GLUTAMATE Quantifying blood-brain permeability Observing brain activation and perfusion
Practice-based Evidence for Clinical Practice Improvement Examines three sets of factors and the interaction among them: PATIENT (CASE MIX CLASSIFICATION ; SEVERITY OF ILLNESS) PROCESS (TREATMENTS, INTERVENTIONS, MEDICATIONS) OUTCOMES (CLINICAL, COST, LENGTH OF STAY)
PBE: Effectiveness Research(Attention To Details Of The Process Of Care) ANSWERS THE QUESTION: does a treatment work under usual conditions of care? 2. SEEKS TO IDENTIFY NATURAL VARIATION IN THE POPULATION AND DETERMINE HOW INTERVENTIONS AFFECT DIFFERENT POPULATIONS
PBE Creates a comprehensive, complex databases, that include detailed patient-specific descriptions, severity-of-illness measures, and characterizations of treatments for large samples of patients. (examples; stroke rehabilitation, sepsis evaluations for infants with bronchiolitis, pressure ulcers)
