Study Notes

Evidence-Based Practice

Defined as the conscientious, explicit, and judicious use of evidence in patient care decisions.
Challenges traditional practices like clinical freedom and reliance on personal experience, advocating for data-driven approaches.
Influential figures include Sackett and colleagues from McMaster University.

Hierarchy of Evidence

Randomized Controlled Trials (RCTs) minimize bias, involving random allocation of subjects to different treatment groups for comparative analysis.
Development stages include perception of need, anecdotal reports, early experiments, and high-quality evidence leading to guideline endorsement and implementation.

Electronic Patient Record (EPR)

EPR connects various medical data like prescriptions and diagnostic categories, enhancing clinical decision support.
Facilitates learning health systems utilizing AI and machine learning for improved patient outcomes and strategy formulation.

Big Data in Health

Defined by the four Vs: volume, variety, velocity, and veracity.
Enables analysis of extensive and complex datasets, facilitating answers to previously unanswerable health questions.

Impact of Antibiotics on Health

Emerging evidence suggests antibiotics may elevate risks for non-infectious diseases, including bowel carcinoma and rheumatoid arthritis, potentially via microbiome disruptions.

National Institute for Health and Care Excellence (NICE)

Established to provide guidance on health promotion, disease prevention, and treatment.
Evolved from the National Institute for Clinical Excellence, expanding to cover public health and social care.

Precision Medicine

Shifting focus from population-based treatment approaches to personalized medicine, tailored to individual characteristics and needs.
Incorporates pharmacogenomics to understand genetic influences on drug responses, aiming to enhance treatment efficacy through biomarker identification.

Implementation Science

Focuses on strategies to promote the uptake of research findings into routine healthcare practices to improve outcomes.

Key Lectures and Dates
