Health Epidemiology

Health is an essential factor for all human beings. For all humans, health is a critical factor. An individual's ability to meet life's challenges and retain his or her capacity for optimal functioning is reflected in his or her condition of health. This needs the physical, mental, and biological parts of one's constitution to maintain a degree of functioning that has a favorable influence and support for one another.

Screening: Sensitivity and Specificity
True positive and true negative are determined using a gold standard, such as an established reference assay or a definitive clinical diagnosis. TrueFalse When FDA-approved or FDA-cleared methods are incorporated, the test performance is verified by using the purchased reagent sets to test validation specimens. This verification establishes that the results of the commercial test performed in the individual laboratory are as predicted by the developer. TrueFalse The negative predictive value is the degree that a particular test result corresponds with the presence of a clinical state, such as disease symptoms or response to therapeutic agent. TrueFalse The positive predictive value is the clinical specificity of the test, that is, the absence of that test result in the absence of the disease state or response. TrueFalse Answ

True or False? An active-control trial is the best option for researchers hoping to test a newly devised therapy for a life-threatening illness among individuals with the illness, when a previously devised treatment is available for the illness.
A patient scores 67 points on an assessment form. The clinician finds a study in the literature that reports a standard error of measurement (SEM) of 4.5 for this outcome measure. What is an appropriate interpretation of the patient’s score? Recall that the Zalpha value for a 90%CI is 1.64 and Zalpha value for a 80%CI is 1.28. The clinician can be 90% confident that the patient's score lies between 60 and 74. Upon repeated evaluations, 90% of stable patients will change by less than 15 points. Upon repeated evaluations, 80% of stable patients will change by less than 10 points. The clinician can be 80% confident that the patient's score lies between 65 and 70.

Manufacturers of self-contained test kits apply for and receive Food and Drug Administration (FDA) approval for their particular test to be on the Clinical Laboratory Improvement Amendment (CLIA) waived list. To find out if your particular brand of self-contained test kit is on the CLIA waived list, access an up-to-date listing at the FDA website(https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfclia/analyteswaived.cfm (Links to an external site.)) and use the key search term “Currently Waived Analytes” (be forewarned, though, that the list is very long) (Cited from Chap. 37). Research the link to the FDA to find your kit name on the list. Discuss the following questions: Why would it be important to have this kit listed here? Can a POL use kits that are not listed?
