临床试验中的避孕药使用通常是通过自我报告来衡量的，这可能是不准确的，或者是尿液药物筛查，这可能是侵入性的和繁重的。可以自动检测可卡因使用并且可以在日常生活中方便地佩戴的设备可以提供若干益处。AutoSense是一种可穿戴的生理监测套件，可以检测可卡因的使用，但作为监测可卡因使用的方法，它可能受到限制，因为它需要佩戴带有电极的胸带。本文介绍了一个项目的设计，原理和方法，该项目旨在建立和扩展以前的工作，通过可穿戴的，不显眼的移动的传感器技术来检测可卡因的使用方法的发展。为此，腕戴式传感器套件（即，将开发和评价MotionSense HRV）。使用可卡因的参与者（N = 25）将被要求在清醒时间佩戴MotionSense HRV和AutoSense两周。药物使用将通过每周三次的尿液药物筛查和自我报告进行评估，并将用于隔离可卡因使用期，将其与其他药物使用区分开来。本研究将提供关于使用腕戴式装置检测可卡因使用的可行性和可接受性的信息。
Cocaine use in clinical trials is often measured via self-report, which can be inaccurate, or urine drug screens, which can be intrusive and burdensome. Devices that can automatically detect cocaine use and can be worn conveniently in daily life may provide several benefits. AutoSense is a wearable, physiological-monitoring suite that can detect cocaine use, but it may be limited as a method for monitoring cocaine use because it requires wearing a chestband with electrodes. This paper describes the design, rationale, and methodology of a project that seeks to build upon and extend previous work in the development of methods to detect cocaine use via wearable, unobtrusive mobile sensor technologies. To this end, a wrist-worn sensor suite (i.e., MotionSense HRV) will be developed and evaluated. Participants who use cocaine (N = 25) will be asked to wear MotionSense HRV and AutoSense for two weeks during waking hours. Drug use will be assessed via thrice-weekly urine drug screens and self-reports, and will be used to isolate periods of cocaine use that will be differentiated from other drug use. The present study will provide information on the feasibility and acceptability of using a wrist-worn device to detect cocaine use.
