"One of the things I enjoyed most about this book was
being able to examine actual sensitivities, specificities, and
likelihood ratios of various decision instruments and diagnostic
tests that I use daily. It was also enlightening to learn
several diagnostic strategies and decision instruments that I
previously had not used." (Annals of Emergency
Medicine, 1 August 2013)

"This is an excellent resource for clinicians seeking to
provide evidence-based care in emergency medicine. It is a
comprehensive and reliable resource that helps reach a balance
between overuse and underuse of diagnostic testing. The information
is presented in a concise format that can be used during clinical
encounters or for more exhaustive reviews of the literature
surrounding a clinical question. As evidence-based emergency
medicine is a rapidly changing and advancing field, this updated
edition is certainly justified." (Doody's,
