Study Notes

Section VI: Critical Thinking, Research, and Quality Improvement

  • Critical Thinking: Intellectual discipline actively analyzing, assessing, evaluating, and synthesizing elements of a situation. A crucial component of "well-cultivated" critical thinking is developing awareness of thought, reasoning, problem-solving.
  • 'Aspects of critical thinking': includes awareness of thought processes, effort to address complex elements of a situation, development of purposeful thinking using reasoning about problems or situations, and effective communication with others.
  • Thinking elements: these include points of view (individual orientations), purpose (individual goals), questions (problems), information (facts), interpretations, concepts, assumptions, and their implications. Attributes of critical thinkers include open-mindedness, patience, confidence in seeking truth, courage to acknowledge errors, neutral perspectives, keen observation, ability to accept criticism, and good communication skills.
  • Critical thinking in healthcare: is a skill and attitude, useful for improving patient care processes. It prevents medical errors by projecting and identifying consequences.

Research

  • Research terms:
    • Incidence: The rate of new cases of disease or injury within a specified timeframe
    • Incidence proportion/rate: Proportion of a disease-free group that develops disease, is injured, or dies in a specific timeframe.
    • Prevalence: The total number of existing cases (old and new) of disease at a specific point or period within a population.
    • Morbidity: the rate at which an illness occurs in a population
    • Mortality: the death rate reflecting the number of deaths in a population

Research Design

  • Qualitative Research: Explores phenomena within contexts. Utilizes small sample sizes, collecting data until saturation (no new data emerges). Evaluates themes. Examples include phenomenology, content analysis, grounded theory.
  • Quantitative Research: Identifies relationships and determines cause-effect. May involve large or small sample sizes, depending on the objectives. Data collection is focused on outcomes and relationships. Example methodologies include study designs, comparing outcomes, statistical analyses.

Evidence-Based Practice (EBP)

  • EBP components: integrates best available evidence, clinical expertise, and patient preferences.
  • Uses of EBP: Defines healthcare processes, develops policies and procedures, creates management tools (protocols/pathways). Provides guidance for individual patient care.

Data Collection and Analysis

  • Power Analysis: A statistical method to determine the optimal sample size for research questions.
  • Descriptive Statistics: Summarize data using measures of central tendency (mean, median, mode) and variability (range, standard deviation).
  • Inferential Statistics: Tests hypotheses and the relationships between findings in a sample and the population.
  • Randomized Controlled Trials (RCTs): Studies with random allocation of participants into intervention groups.
  • Cohort Studies: Comparisons of large groups of individuals to research causes of a disease, certain clinical outcomes, or links. These can be either retrospective or prospective.
  • Meta-Analysis: Combines findings from various studies. Aims to provide comprehensive estimates of the "effect size" rather than relying on single studies.
  • Systematic Reviews: Evaluates existing research on a topic and summarizes findings; may be used to create or refine practice guidelines.
