Hypertension is a highly prevalent, chronic cardiovascular disease with considerable impacts to population health. Although hypertensive urgencies are common encounters in emergency departments (ED), there is a lack of clear guidance for their clinical management. A poorly managed hypertensive urgency can leave the patient with continuing severe hypertension and at increased risk of end-organ damage. The objective of this study is to determine the current management strategies for hypertensive urgencies in Queensland EDs, and to better understand the reasons for their use. We will survey Queensland ED physicians about their use of and opinions about current management strategies for hypertensive urgencies. We will also conduct a pilot single-site observational study of management strategies for hypertensive urgencies. The findings of this study will inform the design of future research to improve management of hypertensive urgencies in EDs.
