Detection of hypertension in accident and emergency departments
Insights
Elevated blood pressure readings in the Accident and Emergency Department can indicate hypertension. Informing general practitioners of these findings is crucial for patient care and timely hypertension management.
Area of Science:
- Cardiology
- Public Health
- Emergency Medicine
Background:
- Blood pressure is routinely measured for non-ambulatory patients in Accident and Emergency (A&E) departments.
- Elevated readings in A&E are often disregarded due to concerns about their significance.
- General practitioners (GPs) are not consistently informed of these elevated readings.
Purpose of the Study:
- To investigate the significance of single, elevated blood pressure readings in A&E patients.
- To determine if these readings are indicative of underlying hypertension.
- To emphasize the importance of communicating A&E blood pressure findings to GPs.
Main Methods:
- Sixty non-ambulatory patients with a single elevated blood pressure reading in the A&E department were identified.
- These patients underwent a follow-up assessment in a controlled, relaxed environment.
- Outcomes were compared with subsequent GP assessments and treatment initiation.
Main Results:
- Fifteen out of sixty patients (25%) maintained elevated blood pressure readings upon review.
- Fourteen of these 15 patients were subsequently diagnosed and treated for hypertension by their GPs.
- This suggests a significant correlation between A&E elevated readings and actual hypertension.
Conclusions:
- Single elevated blood pressure readings in A&E are valuable indicators of potential hypertension.
- Effective communication between A&E departments and GPs regarding incidental high blood pressure readings is essential.
- Prompt GP notification can facilitate early diagnosis and management of hypertension.
Abstract:
Routine blood pressure measurements are performed on all non-ambulatory patients attending the Accident and Emergency Department, Leicester Royal Infirmary, England. However, the patient's general practitioner is not always informed of the reading, even if it is found to be raised. One of the chief reasons for this omission is the fact that single, elevated blood pressure readings taken in an accident and emergency department are considered to be of doubtful significance. Sixty patients with a single, elevated blood pressure measurement were studied. Fifteen of these patients were found to continue to have an elevated blood pressure measurement when reviewed in a quiet, relaxed environment. Fourteen of these 15 patients are currently being treated for hypertension after independent assessment by their family practitioners. It was concluded that single, elevated blood pressure readings are useful indicators of hypertension in non-ambulatory patients attending accident and emergency departments. It is, therefore, important to inform general practitioners of incidentally raised blood pressure readings.
