You decide to test this screening test on a larger population, so you find 235501 people who agree to be tested and 5849 people test positive.

Given this information, you can determine the prevalence of disease in the population you studied. Report this in whole cases per 1000 persons per year.

Answer #1

Ans:

prevalence of disease=100*number of people with disease/total number of people

=100*5849/235501

=2.5 %

So, prevalence of disease( per 1000 persons per year)=(2.5/100)*1000=25 per 1000 person

    Suppose that your company has just developed a new screening test for a disease and you are in charge of testing its validity and feasibility. You decide to evaluate the test on 1000 individuals and compare the results of the new test to the gold standard. You know the prevalence of disease in your population is 30%. The screening test gave a positive result for 292 individuals. Two hundred eighty-five (285) of these individuals actually had the disease on the...

    Consider a small town that has a population of 1,000 people. It is known that in this town, 10 people are infected with a rare disease. The remaining 990 people are NOT infected with the disease. This data is known with certainty. Recently, The FDA (Food and Drug administration) developed a test that determines if a person is infected with this disease. However, as with most test of this nature, it is not foolproof proof as there are a certain...

    A new screening test for Lyme disease is developed for use in the general population. The sensitivity and specificity of the new test are 60% and 70%, respectively. Three hundred people are screened at a clinic during the first year the new test is implemented. Assume the true prevalence of Lyme disease among clinic attendees is 10%. Calculate the following values: The predictive value of a positive test The predictive value of a negative test

    Although the concepts of sensitivity and specificity are usually applied to diagnostic laboratory or screening tests, they are equally valid for other tests that indicate the presence or absence of disease. These may be tests designed to elicit certain physical signs of disease by examination (e.g. hypertension, cervical cancer, neurological defects, and tendency to hemorrhage) or questions aimed at uncovering symptoms. Suppose that a short psychometric questionnaire that was devised to detect undiagnosed cases of personality disorder was found, after...

    Use the following information to answer questions. A new screening test for Lyme Disease is being evaluated. It was administered to 1,235 people in southern Maine. While 115 people with the disease tested positive for it another 47 people who do not have disease tested positive for Lyme. 721 people who did not have Lyme tested negative. [Data are fictitious but realistic.] Using the data above, complete a 2x2 table:

    2. Two simple and inexpensive screening methods have been developed to identify individuals with HIV infection at routine medical check-ups. To study the sensitivity and specificity, both methods were tested on 12860 persons who underwent a simultaneous and thorough clinical examination that was considered to give an accurate diagnosis. There were 1900 cases of disease as diagnosed by clinical methods. The Screening test #1 was positive for a total of 1000 people, including 800 with active HIV infection. The screening...

    Suppose next that we have even less knowledge of our patient, and we are only given the accuracy of the blood test and prevalence of the disease in our population. We are told that the blood test is 98 percent reliable, this means that the test will yield an accurate positive result in 98% of the cases where the disease is actually present. Gestational diabetes affects 9 percent of the population in our patient’s age group, and that our test...

    A screening test for a rare form of TB has a 7% false positive rate (i.e. indicates the presence of the disease in people who do not have it). The test has an 8% false negative rate (i.e. indicates the absence of the disease in people who do have it). In a population of which 0.6% have the disease, what is the probability that someone who tests positive has the disease?
