Screening (medicine) - Principles of Screening

Principles of Screening

World Health Organization guidelines were published in 1968, but are still applicable today.

  1. The condition should be an important health problem.
  2. There should be a treatment for the condition.
  3. Facilities for diagnosis and treatment should be available.
  4. There should be a latent stage of the disease.
  5. There should be a test or examination for the condition.
  6. The test should be acceptable to the population.
  7. The natural history of the disease should be adequately understood.
  8. There should be an agreed policy on whom to treat.
  9. The total cost of finding a case should be economically balanced in relation to medical expenditure as a whole.
  10. Case-finding should be a continuous process, not just a "once and for all" project.
