Will the resulting post-test probabil- ity move the probability across the testing or treatment threshold? If not generic 5 mg haldol with amex, either do not do the test generic haldol 5mg on line, or be prepared to do a second or even a third test to confirm the diagnosis discount haldol 1.5 mg mastercard. Next, is the patient interested in having the test done and are they going to be “part of the team? Give the information to the patient in a manner they can understand and then ask them if they want to go through with the testing. They ought to understand the risks of disease, and of correct and incorrect results of testing, and the ramifications of a positive and negative test results. The decision making for this problem is very complex and should be done through careful consideration of all of the options and the patients’ situation such as age, general health, and the presence of other medical conditions. Finally, how will a positive or negative result help the patient reach his or her goals for treatment? If the patient has “heartburn” and you no longer sus- pect a cardiac problem, but suspect gastritis or peptic ulcers, will doing a test for Helicobacter pylori infection as a cause of ulcers and treatment with specific anti-microbial drugs if positive, or symptomatic treatment if negative, satisfy the patient that he or she does not have a gastric carcinoma? If not, then endoscopy, Sources of bias and critical appraisal of studies of diagnostic tests 309 the gold standard in this case, ought to be considered without stopping for the intermediate test. Studies of diagnostic tests should determine the sensitivity and specificity of the test under varying circumstances. The prevalence of disease in the popula- tion studied may be very different from that in most clinical practices. There- fore, predictive values reported in the literature should be reserved for validation studies and studies of the use of the test under well-defined clinical conditions. Remember that the predictive value of a test is dependent not only on the likeli- hood ratios, but also very directly on the pretest probability of disease. Final thoughts about diagnostic test studies It is critical to realize that studies of diagnostic tests done in the past were often done using different methodology than what is now recommended. Many of the studies done years ago only looked for the correlation between a diagnostic test and the final diagnosis. For example, a study of pneumonia might look at all physical examination findings for patients who were subjected to chest x-rays, and determine which correlated most closely with a positive chest x-ray, the gold standard. First, the patients are selected by inclusion criteria that include getting the test done, here a chest x-ray, which already narrows down the probability that they have the illness. Second, correlation only tells us that you are more or less likely to find a certain clinical finding with an illness. It does not tell you what the probability of the illness is after applica- tion of that finding or test. The correlation does not give the same useful infor- mation that you get from likelihood ratios or sensitivity and specificity. Those will tell the clinician how certain diagnostic findings correlate with the presence of illness and how to use those clinical findings to determine the presence or absence of disease. You have attempted to tinge it with romanticism, which produces much the same effect as if you worked a love-story or an elopement into the fifth proposition of Euclid. Sir Arthur Conan Doyle (1859–1930): The Sign of Four, 1890 Learning objectives In this chapter you will learn: r the attributes of a good screening test r the effects of lead-time and length-time biases and how to recognize them in evaluating a screening test r how to evaluate the usefulness of a screening test r how to evaluate studies of screening tests Introduction Screening tests are defined as diagnostic tests that are useful in detecting disease in asymptomatic or presymptomatic persons. The goal of all screening tests is to diagnose the disease at a stage when it is more easily curable (Fig. This is usually earlier than the symptomatic stage and is one of the reasons for doing a diagnostic test to screen for disease. Screening tests must rise to a higher level of utility since the majority of people being screened derive no benefit from having the test done. Because the vast majority of people who are screened do not have the disease, they get minimal reassurance from a negative test because their pretest probability of disease was low before the test was even done. However, for many people, the psychological relief of having a negative test, especially for something they are really scared of, is a worthwhile positive outcome. Usual diagnosis in patients Treatment resulting in presenting with signs or prolonged period of time symptoms of disease.
