Evaluating the severity of dermatologic disorders.

Assessment of a patient's disease severity is an essential component of formulating therapeutic strategies. However, disorders of the skin are often not amenable to strict classification criteria, and the dermatologist relies upon personal thresholds of severity when assessing the patient's overall condition. A number of grading systems have arisen, primarily from the need for standardized end points in clinical trials; in some circumstances, these severity assessments may assist the clinician in the evaluation and treatment of dermatologic disease. In this review, we will summarize the results of available severity scores of frequently encountered dermatologic disorders and discuss their utility in the management of disease in a clinician's office.
