    Study Notes

    Evidence-Based Practice

    • Evidence-based medicine emphasizes the use of evidence for individualized patient care, challenging traditional notions of clinical freedom and established practices.
    • Developed by Sackett and colleagues at McMaster University, it promotes rigorous decision-making supported by evidence rather than solely physician experience.

    Hierarchy of Evidence

    • The hierarchy categorizes evidence, progressing from anecdotal experiences to high-quality randomized controlled trials (RCTs).
    • RCTs minimize bias by randomly assigning subjects to experimental and control groups, crucial for testing treatment effectiveness.

    Electronic Patient Record (EPR)

    • EPRs link prescriptions, diagnostic categories, and clinical decision support systems, enhancing patient care.
    • Allows for the analysis of vast patient data sets, driving insights into health trends and disease associations.

    Big Data in Health Informatics

    • Big data encompasses large, complex datasets characterized by greater variety, volume, velocity, and veracity—often unmanageable by traditional software.
    • Utilizes patient records for in-depth analysis, aiding in understanding relationships between treatments (e.g., antibiotics and non-infectious diseases).

    Implementation Science

    • Focuses on how to effectively integrate evidence-based practices into healthcare settings, addressing barriers to adoption.

    National Institute for Health and Care Excellence (NICE)

    • NICE provides national guidance for health promotion, illness prevention, and treatment, evolving from its origins as the National Institute for Clinical Excellence.
    • Has expanded to include public health and social care guidance since becoming an independent body in 2013.

    Precision Medicine

    • Aims to tailor treatments to individual patients rather than populations, based on genetic and biomolecular insights.
    • Involves pharmacogenomics to understand how genetics influence drug responses, aiming to identify effective treatments for unique patient profiles.

    Context of Evidence

    • Highlights the importance of synthesizing diverse evidence sources, including perspectives from patients, researchers, and clinicians.
    • Signifies the fast-paced evolution of knowledge, particularly noted during crises like COVID-19.

    Clinical Decision Support Systems (CDSS)

    • These systems provide healthcare professionals with knowledge and patient-specific information to enhance decision-making in clinical practice.
