Background:
Emergency department (ED)-based screening and referral of patients with elevated blood pressure (BP) is recommended by 2006 and 2013 American College of Emergency Physicians (ACEP) guidelines, however, it is unknown if these recommendations or disparities in care impact clinical practice.
Objectives:
(1) Assess temporal trends in antihypertensive prescriptions, outpatient follow-up referrals, and diagnosis of hypertension (HTN)/elevated BP and (2) identify potential disparities by patient characteristics.
Methods:
Using the 2005–2015 National Hospital Ambulatory Medical Care Survey, we examined the frequency and trends overtime of antihypertensive prescriptions, outpatient follow-up referrals, and BP diagnoses for US ED visits by adult patients with an elevated triage BP and identified potential disparities in management by patient demography and socioeconomic status.
Results:
Of the 594 million eligible ED visits by patients from 2005–2015, 1.2% (1.0 −1.4%) received antihypertensive prescriptions at discharge, 82.3% (80.0 – 83.6%) outpatient follow-up referrals, and 2.1% (1.9–2.4%) a HTN/elevated BP diagnosis. There were small annual increases over time in the odds of antihypertensive prescriptions at discharge (aOR 1.05 (1.00, 1.10)), follow-up referrals (aOR 1.04 (1.01, 1.07)), and HTN/elevated BP diagnosis (aOR 1.05 (1.02, 1.08)). For BPs ≥160/100 mm Hg, prescriptions were more common for Blacks (aOR 2.36 (1.93, 2.88)) and uninsured patients (aOR 1.81 (1.38, 2.38)), and diagnoses were more common for Blacks (aOR 1.95 (1.70, 2.24)) and uninsured patients (aOR 1.30 (1.09, 1.55)).
Discussion:
These data suggest little change in and the need for improvement in the management of ED patients with elevated BP, despite ACEP guidelines, and raise concern about patient care disparities.
