Problem Statement

The Clinical Opiate Withdrawal Scale (COWS) is a pen-and-paper assessment administered by physicians in a clinical setting to score the severity of withdrawal symptoms in an opioid user. The development of an electronic Clinical Opiate Withdrawal Scale (eCOWS) will allow for immediate, remote assessment of withdrawal symptoms within a clinical setting—as opposed to a delay in the matter of interface with a physician. Real-time data obtained by wearable sensors is capable of achieving faster, more accurate assessments of withdrawal patients and more suitable treatment to combat withdrawal.

What is eCOWS?

The electronic Clinical Opiate Withdrawal Scale (eCOWS) is a variation of an assessment used in outpatient and inpatient settings to monitor and rate common signs and symptoms of opiate withdrawal. The eCOWS will reproducibly rate and continuously monitor the 11-item scale of withdrawal symptoms. The 11 items on this scale consist of pupil dilation, irritability, bone/joint aches, restlessness, skin piloerection, yawning, resting pulse rate (BPM), sweating, runny nose or tearing, GI Upset, and tremors. There is some concern with the level of subjectivity within the items on COWS. The eCOWS aims to improve on the objectivity of this evaluation tool.
