Abstract
Accurate blood pressure (BP) measurement is critical for assessing cardiovascular health and for the early diagnosis and management of hypertension. Inaccurate BP measurements, whether overestimating or underestimating true BP, can lead to misdiagnosis of cardiovascular risk or inappropriate treatment, including overmedication. In this context, home BP monitoring is ideal as it provides more accurate BP readings while avoiding white-coat hypertension and identifying masked hypertension. PURPOSE: To evaluate the accuracy of a new automated BP device intended for simplified home use according to the requirements of the Association for the Advancement of Medical Instrumentation/European Society of Hypertension/International Organization for Standardization (AAMI/ESH/ISO) Universal Standard. METHODS: A total of 72 adults (Age: 22 ± 4 years, Female: 38) who met the age, sex, blood pressure, and arm circumference distribution criteria of the AAMI/ESH/ISO Universal Standard requirements were recruited and tested. Brachial BP was measured in the same-arm using two simultaneous methods: 1) by two trained observers using a dual-headed stethoscope and a calibrated aneroid monitor (reference), and 2) a new automated BP device (Telli Health, Miami, FL, USA). Two cuff sizes of the test device, appropriate for arm circumferences of 22–42 cm and 22–29 cm, were used according to participants’ arm sizes. RESULTS: For validation criterion 1, the mean difference (test device minus reference BP) for all BP readings was 4.2 ± 7.2 mmHg for systolic BP and −0.6 ± 5.2 mmHg for diastolic BP (threshold ≤ 5 ± 8 mmHg). For validation criterion 2, the standard deviation of the mean BP differences between the test device and reference BP per individual (n = 72) was 6.4 mmHg for systolic BP and 4.6 mmHg for diastolic BP (threshold ≤ 6.95 and 6.55 mmHg, respectively). In addition, systolic and diastolic BP measurements obtained from the test device were strongly correlated with reference measurements (systolic BP: r = 0.846; diastolic BP: r = 0.838; p < 0.05). CONCLUSION: The automated home BP monitor fulfilled all the requirements of the AAMI/ESH/ISO Universal Standard and therefore can be recommended for self-monitoring of BP at home.
