What is evidence-based public health?

• Evidence-based public health is the
  conscientious, explicit, judicious use of the
  current best evidence in making  decisions in
  routine PH practice, and in developing PH
  policies and programs.
• EBPH practice requires integrating practitioner
  expertise, accumulated PH and basic science
  knowledge, and regulatory requirements,  with
  best evidence from systematic research.
•   

• Definiton based on Sackett DL et al. Evidence
  based medicine what it is and what it isn't.
• BMJ 1996 Jan 13 312 (7023) 71-2.

  importance would require perusing about 6,000

• If you only read 2 articles a day, at the end of
  year you would be 60 centuries behind.

  The Journal of the American Medical Association.
