This systematic review provides an assessment of the diagnostic accuracy of various historical, physical, and clinical examination features for aortic dissection. Nine articles were included, with moderate to high heterogeneity. Limitations to general practice include risk of selection bias and partial verification bias. Risk scores were included, but their use is not recommended at this time.

Multicenter Study Observational Study
Multicenter Evaluation of the YEARS Criteria in Emergency Department Patients Evaluated for Pulmonary Embolism.
It may be possible to safely rule out pulmonary embolism (PE) in patients with low pretest probability (PTP) using a higher than standard D-dimer threshold. The YEARS criteria, which include three questions from the Wells PE score to identify low-PTP patients and a variable D-dimer threshold, was recently shown to decrease the need for imaging to rule out PE by 14% in a multicenter study in the Netherlands. However, the YEARS approach has not been studied in the United States. ⋯ D-dimer adjustment based on PTP may result in a reduced need for imaging to evaluate possible PE, with some additional missed PE but no decrease in NPV.
