Objective: This study aimed to evaluate the accuracy of the automated Health & Life oscillometric wrist blood pressure monitor HL168JD for home blood pressure monitoring according to the European Society of Hypertension International Protocol.
Methods: Systolic and diastolic blood pressures were sequentially measured in 33 adult Chinese using the mercury sphygmomanometer (two observers) and the HL168JD device (one supervisor). Ninety-nine pairs of comparisons were obtained from 15 participants in phase 1 and further 18 participants in phase 2 of the validation study. Data analysis was performed using the ESHIP Analyzer program.
Results: The HL168JD device successfully passed phase 1 of the validation study with a number of absolute differences between device and observers within 5, 10, and 15 mmHg for at least 33/45, 41/45, and 45/45 measurements, respectively. The device also achieved the targets for phase 2.1, with 71/99, 90/99, and 98/99 differences within 5, 10, and 15 mmHg, respectively, for systolic blood pressure, and with 73/99, 89/99, and 99/99 within 5, 10, and 15 mmHg, respectively, for diastolic blood pressure. In phase 2.2, 27 and 26 participants had at least 2 of the 3 device-observers differences within 5 mmHg for systolic and diastolic blood pressure, respectively.
Conclusion: The Health & Life wrist blood pressure monitor HL168JD can be recommended for home use in adults.
