Define the positive predictive value of a test and explain how to evaluate this measure.
What will be an ideal response?
One way to assess screening results is to evaluate the positive predictive value of a test, defined as the proportion of people who test positive for a disease who actually have the disease. While this measure is important clinically, its value is dependent upon the prevalence of the disease, which may vary. This value may be artificially high if the prevalence of the disease is high. In this case, using the sensitivity or specificity of the test may be a better measure. The formula for calculating positive predictive values is: Positive Predictive Value = a/(a + c)

Your 56-year-old patient is in bed and unable to speak. Family members state that he has had a previous stroke and has been bedridden since, but has always been able to talk, until a few hours ago when his speech became garbled. They also state that the last stroke left him paralyzed on his left side. Your assessment reveals him unable to speak, but with an open airway, adequate respirations, and
a strong radial pulse. Additionally you note that he is unable to move his right arm. Vital signs are within normal limits.
