SCRAM CAM Research

Comparative Study and Evaluation of SCRAM Use, Recidivism Rates, and Characteristics

The impact of SCRAM CAM on the rate of repeat drinking and driving offenses (i.e., recidivism) was assessed for the first two years following arrest for 837 offenders in Wisconsin and 672 offenders in Nebraska. There was virtually no recidivism while on SCRAM CAM. For the offenders who recidivated, those assigned to SCRAM CAM recidivated later, meaning the device delayed recidivism. [Download]


Field and Laboratory Alcohol Detection With 2 Types of Transdermal Devices

Two types of transdermal electrochemical sensors that detect alcohol at the skin surface were evaluated. One, the AMS SCRAM device, is locked onto the ankle and is based on a fuel cell sensor; the other, a Giner WrisTAS device, worn on the wrist, is based on a proton exchange membrane. SCRAM is used by several court systems in the United States to monitor alcohol offenders, WrisTAS, a research prototype, is not commercially available. [Download]


Evaluating Transdermal Alcohol Measuring Devices

This report is an evaluation study of two types of transdermal devices that detect alcohol at the skin surface representing two types of electrochemical sensing technology: The AMS SCRAM ankle device and the Giner WrisTAS wrist device were worn concurrently for the evaluation by 22 paid research subjects (15 males, 7 females), for a combined total of 96 weeks.
