5 –2 have little effect. It is also possible to use likelihood ratios when considering a sequence of independent tests (for example, an electrocardiogram followed by troponin I testing for potential ACS). Likelihood ratios can also be multiplied in series. Using odds, probabilities and likelihood ratios: an example The best way to describe odds, probabilities and likelihood ratios are by using a clinical example. Using D-dimer as an example, let’s assume that the sensitivity is 94% and the specificity is 45%.

3). The stepwise nature of the CCR makes it somewhat more complicated than the NEXUS criteria and a bit more difficult to remember. However, if a patient satisfies all of the criteria, the decision rule indicates a low risk of cervical spine injury and radiography can be deferred. The following lists the criteria that must be fulfilled in order to safely defer imaging according to the CCR. Criterion 1: Is there any high-risk factor that mandates radiography? Specifically, does the patient satisfy any of the following: age 65 years or older, paresthesias in any extremity, or a dangerous mechanism of injury (defined as a fall from 1 m or greater, axial load to the head as in a diving injury, motor vehicle crash at a speed in excess of 100 km/h, rollover or ejection, motorized recreational vehicle, bicycle collision)?

They are designed to be simple and to provide a practical decision-making guide to differentiate patients who require testing or treatment from those who do not. 1 Decision rules are derived using a series of research studies on a specific clinical question. They must then be validated and tested in a different population. Each step in the derivation, validation, and external testing of a decision rule involves specific study designs and statistical analyses. e. patient population tested, specific outcomes) have an impact on how the rule should be interpreted and used in clinical practice.
