M8 Epidemiology (SCFHS)

Von Raywat Deonandan, PhD

This course is an introduction to epidemiology and to the epidemiological approach to population-based health care. The basic principles and methods of epidemiology are presented together with many of the applications of epidemiology to clinical practice and public health.
Topics include: dynamics of disease transmission, measuring occurrence of disease, validity and reliability of screening tests, randomized trials, cohort studies, case control, cross-sectional studies, inferences, bias, confounding and interaction.

Course Objectives
By the end of this course the student should be able to:
  • Demonstrate understanding of the mechanisms and dynamics of disease transmission in populations and the risk factors which determine their distribution.
  • Calculate the measures of morbidity and mortality, incidence and prevalence.
  • Assess the validity and reliability of diagnostic and screening tests.
  • Explain the different mechanisms used to describe disease prognosis in quantitative terms for groups of patients.
  • Assess the efficacy of preventive and therapeutic measures via randomized trials.
  • Become knowledgeable about the design and conduct of epidemiological study designs (cohort, cross-sectional, retrospective, and prospective).
