Poor adherence to treatment regimens is hypothesized to be, in part, responsible for the extensive morbidity and mortality associated with asthma. Electronic monitors are the most accurate means available for measuring adherence, but their use has been limited by reports questioning the reliability and validity of their data.
To test the reliability and accuracy of the MDILog (Medtrac Technologies, Lakewood, CO), a new electronic monitor of metered dose inhalers (MDIs), and to test its unique features.
Brief experiments were performed comparing a written diary to the electronic record using three MDILogs. The following features were studied: reporting of time and date of an actuation, recording of the occurrence of an actuation of the MDI, sensing and timing of inhalations, sensing of shaking of the MDI canister, and recording of multiple actuations.
Clocking was accurate 100% of the time. Actuation agreed with the paper record 97% to 100%, inhalation 82% to 100%, shaking 86% to 95%. Agreement of late inhalations and multiple actuations with paper records was at least 98%.
The MDILog yields accurate information and is more reliable than previously described monitors. Its new features allow more detailed study of how patients use inhalers by allowing evaluation of how patients inhale and whether they shake the inhaler canister before use.
据推测，治疗方案依从性差在一定程度上导致了与哮喘相关的广泛发病和死亡。电子监测器是测量依从性最准确的可用手段，但其使用受到对其数据可靠性和有效性的质疑报告的限制。
测试一种新型定量吸入器（MDI）电子监测器MDILog（Medtrac Technologies公司，科罗拉多州莱克伍德）的可靠性和准确性，并测试其独特功能。
使用三台MDILog进行简短实验，将书面日记与电子记录进行比较。研究了以下功能：记录启动时间和日期、记录MDI启动情况、感知和记录吸入时间、感知MDI药罐摇晃情况以及记录多次启动。
计时100%准确。启动情况与纸质记录的一致性为97%至100%，吸入情况为82%至100%，摇晃情况为86%至95%。延迟吸入和多次启动与纸质记录的一致性至少为98%。
MDILog能提供准确信息，且比之前描述的监测器更可靠。其新功能通过评估患者的吸入方式以及使用前是否摇晃药罐，使对患者使用吸入器方式的更详细研究成为可能。
