Diagnosis, treatment, and referral of hypertension in an emergency department.

The authors prospectively audited 500 randomly selected charts of patients seen during a 6-month period ending in October 2008, in the emergency department of a university medical center for the prevalence of hypertension and how it was managed. Of the 187 patients with hypertension, 14 (8%) were treated for hypertension in the emergency department and 99 (53%) were hospitalized or referred to a physician or clinic for follow-up of their hypertension. Much improvement is needed, especially since many of the patients seen in the emergency department do not have a primary care physician.
