Abstract 13197: Characteristics and Outcomes of Patients Presenting With Hypertensive Urgency in the Outpatient Setting

Abstract

Background: Hypertensive urgency is a commonly encountered outpatient problem. Prevalence and short term outcomes of this condition are unknown. JNC VII recommends aggressive BP control over several days. However, a small percentage of patients are sent to the emergency department. It is unknown whether hospital management of these patients is better than outpatient BP management. Methods: Retrospective cohort study of all patients presenting to an office in a large health care system from 2008-2013 with SBP ≥180mmHg or DBP ≥ 110mmHg. We excluded pregnant women and patients referred to the hospital for symptoms or treatment of other conditions. Patients were divided into 2 groups: those sent home and those referred to hospital. We recorded baseline demographic and clinical data. Propensity matched outcomes recorded included MACE (acute coronary syndrome, stroke/TIA) uncontrolled hypertension (≥140/90 mmHg) and hospital admissions. Results: Of 2,199,019 office visits, 58,583 (5%) had hypertensive urgency. Mean age was 63±15 yrs, 58% were females, 76% Caucasian, mean BMI was 31±8 kg/m2 and mean SBP and DBP were 182±16 and 96±16 mmHg. Only 426 (0.7%) patients were referred to the ED/hospital. On propensity matched analysis between the patients referred to the hospital and sent home, there was no significant difference in MACE events at 7 days (0% vs. 0.13%, p=1), 30 days (0.25% vs. 0%, p=1) or 6 months (0.5% vs. 0.13%, p=0.26). Compared to patients sent home, patients referred to the hospital had less uncontrolled hypertension at 1 month (81% vs. 88%, p=0.001) but not at 6 months (65% vs 69%, p=0.16). They also had higher 7- and 30-day hospital admission rates (8.5% vs. 4.9%, p=0.01; 11.8% vs 7.6%, p=0.02). Conclusion: Hypertensive urgency occurs commonly, but the rate of MACE in asymptomatic patients is very low. ED visits increased hospitalizations, but did not improve outcomes. Most patients with hypertensive urgencies still had uncontrolled hypertension at 6 months.
