High Blood Pressure By Itself May Not Be An Emergency: Study


High Blood Pressure By Itself May Not Be An Emergency: Study

Washington : Visits to emergency departments for patients with hypertension increased by 64 percent between 2002 and 2012 while hospitalizations for those visits declined by 28 percent. A study published online yesterday in Annals of Emergency Medicine suggests that aggressive home monitoring of blood pressure may be driving patients to emergency departments despite the lack of other emergency conditions, such as stroke (“A Population-Based Analysis Of Outcomes In Patients With A Primary Diagnosis Of Hypertension In The Emergency Department“).

“We encourage patients to monitor their blood pressure at home if they have been diagnosed with hypertension, but not every high blood pressure reading is an emergency,” said lead study author Clare Atzema, MD, an emergency physician at Sunny brook Health Sciences Centre and a scientist at the Institute for Clinical Evaluative Sciences in Toronto, Ontario, Canada. “Some of the increase in emergency visits is due to the aging of our population, but we suspect that recent public education campaigns recommending home blood pressure monitoring may have inadvertently contributed to the rise in visits for hypertension.”

During the study period in which visits to Ontario emergency departments for hypertension increased from 15,793 to 25,950 per year, the proportion of patients admitted to the hospital as a result decreased from 9.9 percent to 7.1 percent. Among the patients whose emergency department visit ended in admission to the hospital, the most frequent hospital diagnoses were stroke, renal failure and heart failure. The proportion of patients arriving via ambulance increased over time, from 10.7 percent to 14.3 percent.

Mortality was very low: less than 1 percent of patients died within 90 days and only 4.1 percent died within 2 years. Together, hospitalizations for stroke, heart failure, acute myocardial infarction, atrial fibrillation, renal failure, hypertensive encephalopathy and aortic dissection were less than 1 percent at 30 days.

“Stroke remains a huge killer and we do appreciate patients with hypertension being so conscientious about monitoring their readings,” said Dr. Atzema. “Patients should be aware that unless their high blood pressure coincides with symptoms of a medical emergency, such as chest pain, severe headache, nausea or shortness of breath, they probably do not need to visit the ER.  We of course encourage them to follow up as soon as possible with their regular physician. If there is any doubt, come to the emergency department: we would rather have you come without an emergency than stay home with one.”
