Summary

AI-generated

Approximately half of adults in the US are affected by hypertension, and there is wide variation in practice patterns among emergency physicians for managing asymptomatic elevated blood pressure. This clinical policy updates the 2013 ACEP policy by incorporating new evidence to guide emergency physicians on whether initiating antihypertensive medications at ED discharge is safe and effective.

Key Takeaways

  • 1
    Consider initiating outpatient antihypertensive medications for adults discharged from the ED with asymptomatic elevated blood pressure.
  • 2
    Ensure patients with asymptomatic elevated blood pressure are referred for outpatient follow-up.

What's New in This Version

Updates the 2013 clinical policy by incorporating new evidence that demonstrates the efficacy and safety of initiating antihypertensive medications from the ED. The previous policy discouraged routine intervention. This update does not revisit screening for target organ injury or the need for acute blood pressure lowering within the ED.

Evidence Levels

Class IRandomized, controlled trial or meta-analysis of randomized trials; Prospective cohort using a criterion standard or meta-analysis of prospective studies; Population prospective cohort or meta-analysis.
Class XStudies with significant methodologic limitations and/or ultimately determined to not be applicable to the critical question.
Class IINonrandomized trial; Retrospective observational; Retrospective cohort; Case control.
Class IIICase series.

Recommendation Strength

Level AGenerally accepted principles for patient care that reflect a high degree of scientific certainty (e.g., based on evidence from one or more Class I, or multiple Class II studies demonstrating consistent effects).
Level BRecommendations for patient care that may identify a particular strategy or range of strategies that reflect moderate scientific certainty (e.g., based on evidence from one or more Class II studies, or multiple Class III studies demonstrating consistent effects).
Level CRecommendations for patient care that are based on evidence from Class III studies or, in the absence of adequate published literature, based on expert consensus.

Safety & Contraindications

Monitoring Guidance

Patients with asymptomatic elevated blood pressure should be referred for outpatient follow-up.
