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.

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.

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; performance of the monitor below this level was better among women because of their higher transdermal alcohol concentration levels.

Use of Continuous Transdermal Alcohol Monitoring During a Contingency Management Procedure to Reduce Excessive Alcohol Use

This study examined the effectiveness of using transdermal alcohol monitoring as a continuous measure of alcohol use to implement financial contingencies to reduce heavy drinking. Researchers concluded that transdermal alcohol monitoring can be used to implement contingency management programs to reduce excessive alcohol consumption.

Quantitative Determination of Caffeine and Alcohol in Energy Drinks and the Potential to Produce Positive Transdermal Alcohol Concentrations in Human Subjects

The purpose of this study was to determine whether non-alcoholic energy drinks could result in positive “alcohol alerts” based on transdermal alcohol concentration (TAC) using a commercially available electrochemical monitoring device.

Feasibility of Transdermal Ethanol Sensing for the Detection of Intoxicated Drivers

Using a validated model this study looked at the effects that body weight, metabolic rate, and ethanol dose has on the time lag between the blood alcohol concentration and transdermal alcohol concentration.
