Uncontrolled hypertension and hypertensive urgency: One-year single-center emergency department experience.

Abstract

The prevalence of uncontrolled hypertension remains a significant concern in public healthcare systems, including daily practices of emergency departments (ED). We aimed to characterize patients admitted to an ED for elevated blood pressure (BP) and to identify factors leading to hospitalization. This retrospective analysis included all patients admitted to an ED in a tertiary hospital in 2022 due to an acute BP rise without hypertensive emergencies. The studied group (n = 570) constituted 1.5% of all ED admissions in 2022. The median age was 67 years (Q1-Q3) (52-75), 68.9% were females. Systolic BP (200 mm Hg [180-212]) and diastolic BP (105 mm Hg [100-115]) at home were higher than during triage (173 mm Hg [160-190] and 95 mm Hg [84-103], respectively [P <0.0001]). Thirty-nine percent of the studied population had taken BP-lowering agents before ED admission (captopril in 91.8% of cases). In the ED, nitrendipine (54.2%), captopril (38.1%), furosemide (16.3%), urapidil (10.0%), and nitroglycerine (1.9%) were administered. Eventually, a median of 140/82 mm Hg BP was reached in the median time of 288 minutes (202-400). Hospitalization was necessary in 5.4% of patients. The need for furosemide or urapidil administration in the ED doubled the risk of hospitalization (OR, 2.0; P <0.01). Before ED admission, only 17.0% of patients received guidelines-recommended single-pill combination therapy, and 17.6% had already visited ED for uncontrolled hypertension (median of 388 days earlier). Elevated BP is a common reason for admission to the ED. Crucially, improvements in long-term hypertension treatment and education are needed to reduce the number of patients seeking ED care for elevated BP.
