N320 - Research and Evidence-Based Practice

research

• discuss the evolution of nursing research

• compare and contrast quantitative and qualitative research method

Evidence Based Practice (EBP)

• describe evidence-based practice in nursing including the rationale for its use

• outline the steps in implementing evidence-based practice

• read and understand on a beginning level a published reserach article

• use framework toe valuate the salience of a research study

• problem-solving

• specific nursing intervnetions

• mandates analysis/reviews of research findings

EBP - best research evidence

• high quality findings from quantitiative and qualitative studies, clinical trials, and meta-analyses

EBP - Clinical Nursing Expertise

• the nurse’s clinical judgement accumualted skills, critical thinking, and past experiences caring for patients

EBP - Patient values and preferences

• the patient’s unique cultural, background, personal beliefs, financial situation, goals, and comfort levels

PICOT

• patient

• intervention

• comparison

• outcome

• time

• in adult patients with total hip replacements, how effective is pain medication compared to aerboic stretching in controlling post operative pain during the perioperative and recovery time

steps in implementing EBP

• cultivate a spirit of inquiry

• asking the burning clinical question in PICOT format

• search/collect most relevant best practice

• critically appraise the evidence

• integrate

• evaluate

• disseminate

goals of nursing research

• develop scientific knowledge to

  • improve patient care

  • shape clinical practice

  • optimize health outcomes

• guides

  • nursing actions

  • EBP/refines clinical intervneitons

  • optimizing patient/population health outcomes

  • guides health policy and priorities

national institute of nursing research goals

• build the scientific foundation of clinical practice

• prevent disease and disability

• manage and eliminate symptoms cuased by illness

• enhance end of life and pallitative care

• 
  

quantittive research

• formal, objective, and systematic process used to gather and analyze numerical data

• large samples, uses statistical analysis

• randomized control trials, descriptive studies, correlational studies, quai-experimental studies

independent variable

• variable the researcher changes, manipulates, or selects to see if it has an effect

• presumed cause

dependent variable

• variable that the researcher measure sor observes to see how it changes

• presumed effect or outcome that depends on the independent variable

hypothesis

• specific and testable statement that preducts the expected outcome or relationship between two or more cariables in a study

data

• numerical information collected to measure, count, or statistically analyze patterns, behaviors, and relationships

instruments

• biophsiological, psychometric, scales, psychosocial scales, structured surveys, and questionaries

descriptive research

• describe situation/phenomenon

correlational research

• statsitical relationship between two or more variables

quasi-experimental

• cause and effect

• intervention or treatment

experimental

• randomized control trial

steos if quantitative research

• state the research problem

• define purpose of the study

• review related literature

• formulate hypotheses and variables

• select population and sample

• collect data

• analyze data

• communicate finds and conclusions

qualitative nursing research

• systematic, subjective appraoch used to descirbe and promote an understanding of human experiences, emotions, and meanings related to health and illness

• collects words, stories, and observations to explore the lived experiences of patients, families, populations, and nurses

• themes/patterns are identified

  • smaller numbers

  • phenomenology: lived experiences

  • grounded theory: new theroy emerges

  • ethnography: behaviors, values, traiditions, culture/populations

  • qualitative descirptive

  • case study

  • action research

  • narrative inquiry

ethics of clinical research studies

• value

• scientific validity

• fair subject selection

• favorable risk-benefit ratio

• independent review

• informed consent

• respect for enrolled subject

• do no harm

impediments to nursing research

• limited time to participate in research

• restricted access to resource s

• lack of educational preparation
