Cadman et al listed 7 criteria for determining the effectiveness of a community screening program. The authors are from McMaster University and the University of Ottawa in Canada.
(1) The program has been shown to be effective in a randomized trial.
(2) An effective therapy is available for patients with the target disorder.
(3) The burden of the disease justifies screening.
(4) There is a good screening test available (with reasonable sensitivity and specificity for the disorder).
(5) The program reaches the people likely to benefit from screening.
(6) The health system can cope with the program.
(7) Patients who have been identified comply with recommendations and therapy.
An effective community screening program should meet all 7 criteria.
For the implementation I have developed a Likert-scale response format.
