Espejo and colleagues, using data from a prospective cross-sectional study, discovered that patients visiting the emergency department with non-specific complaints who had poor results on the Clock Drawing Test (CDT) had longer hospital stays and higher 30-day mortality rates [1]. Interestingly, in their cohort, the worse the CDT results, the higher the 30-day mortality rate. The CDT is a relatively easy test to administer and can be conveniently used as a screening tool in the emergency department.
