Medical Knowledge Systems

Based on integrating knowledge gained from:

    • the best available research,
    • clinical expertise and
    • patients' values

�Evidence Based

Medicine

Characteristics of�Evidence Based Medicine �(Pros & Cons)

  • gathering information to better diagnose a patient through documented medical research
  • time consuming
  • can contradict original assessments
  • improves assessment of patient
  • improves ability to research information
  • improves on skills of physician
  • Others…

History of Evidence Based Medicine

  • Term “Evidence Based Medicine” was made in 1990s
  • The first Evidence Based Medicine consisted of anecdotal records and historic accounts (story telling, very subjective/personal)
  • 17th century evidence based medicine was based on information from personal journals and (hard to attain) textbooks
  • 1900-1970s evidence based medicine was gathered through textbooks and peer reviewed journals

History of Evidence Based Medicine

  • during the 1970s technology improved ability to gather information through computers and database software
  • Access to the internet has provided loads of information (all of which is not always reliable) but is free and easily accessible.

Role of Patient and Physician in �Evidence Based Medicine

  • Patient
    • needs to be open minded, can be time consuming, potentially more stressful and frustrating, requires trust
  • Physician
    • needs to create clinical questions, research for the best available evidence, critically observe the evidence and then perhaps learn new skills in order to apply the evidence to the individual patient

How Evidence Based Medicine Supports Patient

  • There has to be evidence to treat the patient based on research

  • Patient has more information to make a decision on their treatment

  • Increased chance of successfully treating illness or injury with an alternative approach

      • Treatment

Definition (Continued)

  • A further examination of the role of Traditional knowledge finds that the primary focuses have been:
      • Curing disease and illness
      • Treatment of wounds and injuries
      • Enhancement of the productivity and standardization of primary health care systems & providers (lean program)

What most of us know & have experienced…

Primary care – clinics, nursing homes and schools.

90% of visits and treatments are delivered here.

Secondary care: emergency rooms, referrals for extra expertise or

procedures.

Labs, medical imaging, intensive care etc.

Tertiary care – specialty hospitals or regional centers with expert specialty care.

Ex. Trauma centers, radiation oncology, burn treatment centers etc

��Complementary & Alternative Medicine (CAM)

    • a number of therapeutic and diagnostic practices that exist largely outside the institutions where conventional and traditional health care is taught and provided
    • The history or origins of CAM are vast and spread world wide.

16 of 21

Complementary & Alternative Medicine (CAM)

    • There are conflicting accounts as to the exact creation of CAM, however most academics believe Eastern Medicine initially began treatment of the person first and illness second. (mind – body – soul)

17 of 21

Complementary & Alternative Medicine (CAM)

  • Consists of knowledge developed over generations within various groups.
  • Incorporates… plants, animals, minerals, spiritual therapies, and various exercise techniques
  • * Up to 80% of Asia and African still rely on traditional medicine.
  • Note: Traditional medicine may also be termed contemporary or alternative medicine when used outside of its culture.

18 of 21

Complementary and Alternative Medicine (CAM)

  • Western Medicine (and Western civilization) have historically viewed Eastern medicine and other cultural practices as an alternative to conventional health care.
  • Therefore these practices have become known collectively as “alternative medicine” (it’s a matter of perspective)
  • The boundary between complementary and conventional medicine is blurred and constantly shifting
