Educator Checklist: Principles of a Screening Test
Mark the appropriate column to indicate whether the learner included each element in his or her response. When completed, tally the “Included” column to calculate the learner’s score.
|Included =1||Not Included =0|
|The condition should be an important health problem|
|There should be a recognizable latent or early symptomatic stage|
|The natural history of the condition, including development from latent to declared disease, should be adequately understood|
|There should be an accepted treatment for patients with recognized disease|
|There should be a suitable test or examination that has a high level of accuracy|
|The test should be acceptable to the population|
|Facilities for diagnosis and treatment should be available|
|The cost of screening (including diagnosis and treatment of patients diagnosed) should be economically balanced in relation to possible expenditure on medical care as a whole, and screening should be a continuing process and not a ‘once and for all’ project|
|There should be an agreed policy on whom to treat as patients|
