Hypertension, a major global health risk, is often undiagnosed, particularly in emergency departments. Early screening and intervention in these settings can improve blood pressure control for at-risk patients.
Area of Science:
- Cardiology
- Public Health
- Emergency Medicine
Background:
- Hypertension is a leading global disease risk factor, with over 20% of adults unaware of their condition.
- Over 25% of emergency department (ED) attendees have underlying hypertension, a condition more prevalent in EDs than primary care.
- Subclinical hypertensive disease is highly prevalent in African American populations presenting to EDs with asymptomatic elevated blood pressure.
Purpose of the Study:
- To highlight the critical role of emergency departments in hypertension screening.
- To assess the current referral rates for follow-up care among hypertensive patients in the ED.
- To explore the potential benefits of initiating or adjusting antihypertensive medications in the ED for select patient groups.
Main Methods:
- Analysis of hypertension prevalence in emergency department attendees.
- Review of current follow-up referral practices for hypertensive patients identified in EDs.
- Evaluation of the potential impact of early medical intervention in the ED setting.
Main Results:
- Less than 30% of patients with mild to severe hypertension identified in EDs are referred for follow-up.
- Emergency departments are underutilized for hypertension screening despite strategic placement.
- Early initiation or adjustment of antihypertensive medications in the ED may benefit select patients.
Conclusions:
- Emergency departments represent a missed opportunity for widespread hypertension screening and early intervention.
- Improved referral systems and targeted medical management within EDs are needed to optimize blood pressure control.
- Addressing hypertension in the ED setting, especially in high-prevalence populations, is crucial for public health.

Special considerations while measuring blood pressure
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
Alterations in Blood Pressure
Hypertension (High blood pressure)
Hypertension occurs when blood pressure readings consistently exceed the normal range. It is diagnosed when systolic blood pressure (the top number, indicating pressure while the heart...
