Abstract:
Allocating scarce resources for dysglycemia intervention requires identification of persons who will benefit. Identification has two steps: screening followed by diagnosis. Lowering a screening test's cut-off score identifies more persons with dysglycemia, but causes more normoglycemic persons to receive diagnostic testing. Raising a test's cut-off score reduces needless diagnostic testing, but increases the number falsely identified as not having dysglycemia. With limited budgets for intervention, raising a screening test's cut-off score may be appropriate. With ample budgets, lowering the test's cut-off score may be appropriate. Screening tests are most efficient in populations with high prevalence of dysglycemia.
