  • These fields are subspecialties of internal medicine and thus require an additional fellowship of 2-3 years’ duration in order to practice.
  • Introduce the biomedical model as an extension of the biomedical definition of health given earlier. Modern medicine has looked to two explanations for disease: exposure to infectious agents, i.e. tuberculosis, and changes in physical systems, such as the changes to blood vessels that increase risk for heart disease. Move into thought experiment…..(next slide)
  • Imagine that I release a large quantity of cold virus into the ventilation system of the room, enough to guarantee that everyone in this room is exposed to the virus. Not everyone will develop symptoms – why not? Discuss each of these briefly, in terms of the their effects on the immune system in handling infections.
  • Use multiple languages in a room metaphor to compare biomedical and biopsychosocial models.
  • Use multiple languages in a room metaphor to compare biomedical and biopsychosocial models.
  • Case reports and below are considered clinically relevant but of lower quality that the above layers. So they make good background resources

    12. 12. Shift from Experience-Based Medicine to EBM <ul><ul><li>“ E vidence- B ased M edicine is the conscientious, explicit and judicious use of current best evidence in making decisions about the care of individual patients. [In] practice, [this] means integrating individual clinical experience with the best available external evidence from systematic research.” </li></ul></ul><ul><ul><li>(Sackett et al., 1996. Evidence based medicine: what it is and what it isn't. BMJ , 312 : 71-2) </li></ul></ul>
    13. 13. Principles of EBM <ul><li>Highest quality  </li></ul><ul><li>Lowest quality  </li></ul>Clinical research aims to apply the best available evidence gained from the scientific method to medical decision making <ul><li>So what is “best evidence”? </li></ul>
    14. 14. Evidence B ased M edicine <ul><li>Best practice based on current knowledge </li></ul><ul><ul><li>Formul ate of the probl e m </li></ul></ul><ul><ul><li>Find the evidence </li></ul></ul><ul><ul><li>Critical evaluation of the evidence </li></ul></ul><ul><ul><li>Practical application </li></ul></ul><ul><ul><li>Evaluation of the results </li></ul></ul><ul><li>Evidence based and creative medicine </li></ul>
