Q

What conditions does a screening programme need to fulfil to be treatable?

A

Disease, Test, Treatment, Programme, Implementation

Disease

  • Must be serious
  • Must be treatable
  • Must have known disease progression
  • All primary prevention strategies should have been implemented

Test

  • Simple and safe
  • Should be acceptable to target population
  • Clear diagnostic investigation
  • Sensitivity and specificity must be known

Treatment

  • Should be beneficial to have early treatment
  • Must have treatment available

Q

What is positive and negative predictive value?

Q

What is the difference between lead and length time bias?

A

Lead: early detection confused with increased survival

Length: screening picks up cancers with long latency period so these naturally have better survival
