Continuous Alcohol Monitoring Research
Experiences with SCRAM alcohol monitoring technology in 100 alcohol treatment outpatients
Researchers from the University of Connecticut and Brown University concluded that SCRAM CAM can benefit individuals in outpatient alcohol treatment programs. Four out of five study participants reported that SCRAM CAM helped them reduce their drinking, and 75% said they would wear it for longer than the 12-week study period.

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.

Predictors of Detection of Alcohol Use Episodes Using a Transdermal Alcohol Sensor
The objective of this investigation was to establish the ability of SCRAM CAM to detect different levels of self-reported alcohol consumption and to determine whether gender and body mass index, alcohol dependence, bracelet version, and age of bracelet influenced detection of alcohol use. Researchers concluded SCRAM CAM is very good at detecting 5 or more drinks; the performance of the monitor below this level was better among women because of their higher transdermal alcohol concentration levels.

Transdermal Alcohol Measurement: A Review of the Literature
The body of scientific literature on transdermal alcohol testing dates back almost 70 years. Based on published research in this field, one can conclude that measuring alcohol transdermally on a constant basis provides an effective screen for alcohol consumption and a reasonable approximation of the magnitude of that consumption.

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.

The Effect of Montana’s 24/7 Sobriety Program on DUI Re-arrest: Insights from a Natural Experiment with Limited Administrative Data
This analysis provides additional support for the claim that the 24/7 Sobriety Program is effective at deterring drinking among individuals with histories of alcohol-related crime. The data suggests that Montana’s 24/7 program reduced the probability of re-arrest for DUI 45-70%.

Assessment of the 24/7 Sobriety Program in North Dakota: Participant Behavior During Enrollment
The 24/7 Sobriety Program mandates that repeat impaired driving offenders remain sober as a condition of bond or pre-trial release. The goal is to monitor the most dangerous offenders in North Dakota and require that these individuals remain sober in order to keep roadways safe from hazardous drivers. Results show that drivers significantly improve traffic metrics after enrolling in the program.
