This study examined the variability of blood pressure measurements and prevalence estimates of elevated blood pressure in emergency department (ED) patients using 4 different methods of categorization.
A prospective, observational study was conducted on adult ED patients with elevated triage blood pressures (systolic > or = 140 or diastolic > or = 90 mm Hg). Three blood pressure measurements were obtained on all subjects and categorized as follows: (1) triage measurement only, (2) the mean of the triage and second measurement, (3) the mean of the 3 measurements, and (4) the mean of the second and third measurements.
Of 2192 screened patients, 326 were included in the final analysis with mean triage systolic and diastolic blood pressures of 160 and 90 mm Hg, respectively. Prevalence estimates of elevated blood pressure in this sample ranged from 100% (reference standard: mean triage blood pressure) to the most conservative estimate of 67% (fourth method).
Determination of elevated blood pressure in ED patients is largely dependent on the method of blood pressure categorization.
本研究使用4种不同的分类方法,检验了急诊科(ED)患者血压测量的变异性以及高血压患病率的估计值。
对分诊时血压升高(收缩压≥140或舒张压≥90 mmHg)的成年ED患者进行了一项前瞻性观察研究。对所有受试者进行了三次血压测量,并分类如下:(1)仅分诊测量值,(2)分诊测量值与第二次测量值的平均值,(3)三次测量值的平均值,以及(4)第二次和第三次测量值的平均值。
在2192名筛查患者中,326名被纳入最终分析,分诊时收缩压和舒张压的平均值分别为160和90 mmHg。该样本中高血压患病率的估计值范围从100%(参考标准:分诊血压平均值)到最保守的估计值67%(第四种方法)。
急诊科患者高血压的判定很大程度上取决于血压分类方法。
