His mother says, “All of his drawings are of numbers in different colors and sizes. For the past few months, the patient has spent most of the time alone in his room, listening to music and drawing.

Of all adult patients in the ICU with bacterial bloodstream infections, 96% will have a biomarker value <2.6 ng/mL.Ī 40-year-old woman comes to the office due to new-onset genital lesions. Of all adult patients in the ICU with bacterial bloodstream infections, 4% will have a biomarker value <2.6 ng/mL. Based on a cut point of ≥2.6 ng/mL, 96% of adult patients in the ICU without bacterial bloodstream infections will be incorrectly identified. Based on a cut point of ≥2.6 ng/mL, 96% of adult patients in the ICU with bacterial bloodstream infections will be correctly identified. Based on a cut point of ≥2.6 ng/mL, 4% of adult patients in the ICU without bacterial bloodstream infections will be incorrectly identified. Based on a cut point of ≥2.6 ng/mL, 4% of adult patients in the ICU with bacterial bloodstream infections will be correctly identified.
Which of the following conclusions about the study results is correct? Analysis shows that a biomarker value ≥2.6 ng/mL has a sensitivity of 32% and a specificity of 96% for predicting bloodstream infections. A clinical study compares several cut points for a new biomarker for bacterial bloodstream infection among adult patients in the intensive care unit (ICU) against blood culture results.
