To develop an alarm device for the mechanical compression device displacement (MCD), and further evaluate its effectiveness in clinical use. The alarm device is mainly composed of buzzer, indicator light, magnetic sheet. This is a prospective randomized and controlled study. Four hundred patients who met the inclusion/exclusion criteria were included and randomly assigned to two groups (MCD group vs alarm + MCD group). The primary outcome measures were the sensitivity and specificity of the alarm device to detect MCD displacement, time to hemostasis (TTH), time to ambulation (TTA), time to hospital discharge (TTHD), hospital costs (HC), complication rates, and patient satisfaction. The sensitivity and specificity of the alarm device in detecting MCD displacement were 94.44% and 88.46%, respectively. The study group achieved shorter TTH (p =.034), shorter TTA (p =.021), lower complication rates (p =.025), and better patients' satisfaction (p <.001) compared to the control group. However, no significant difference was observed in TTHD (p =.361) and HC (p =.583). The alarm device is highly sensitive in detecting MCD displacement, while achieving better clinical outcomes compared with artificial monitoring. [ABSTRACT FROM AUTHOR]
