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 |
