SCRAM Continuous Alcohol Monitoring® (SCRAM CAM®) is an innovative way of monitoring alcohol consumption to provide reliable results around the clock. Its success at enforcing sobriety and helping to change behaviours in vulnerable and alcohol-dependent adults has seen its use rise steeply.

The bracelet is worn on the ankle and tests for the presence of alcohol in perspiration in real-time: every 30 minutes, 24 hours a day, 7 days a week. The results are automatically gathered and uploaded without the need for an individual’s participation to highlight the frequency and pattern of their alcohol consumption.

The data speak for themselves: on any given day, 99.4% of all participants are completely sober and compliant while being monitored with SCRAM CAM®. This helps enforce participant sobriety, compliance and accountability.

How does the SCRAM bracelet work?

The principle behind this transdermal form of testing is based on how the human body metabolises alcohol. Once alcohol is absorbed and distributed through the bloodstream, it is eliminated in various forms. About 1–2% of the alcohol is eliminated through the skin in the form of perspiration. The SCRAM bracelet is powered by a small battery, which enables these transdermal emissions to be sampled every 30 minutes, regardless of where the sample donor is.

The technology is so advanced it can differentiate between very low alcohol consumption (such as 1–2 units) and environmental sources. For example, a visit to premises serving alcohol or spillages of alcohol on the skin can be distinguished from actual ingestion. Spilling any product containing alcohol (such as perfume or hairspray) would create a rapid spike in the results, which would be much faster than the body would ever consume alcohol.

The testing results are reported according to how often the Instructing Party requires a report. If the wireless base station is installed at the individual’s home, the data can be automatically transferred twice a day providing the wearer is within the range of the base unit at the appointed times allocated. The base stations are set to communicate at times when the donor would be at home (usually late night and early morning). Alternatively, the data stored in the bracelet could be downloaded during a Walk in Centre visit at least every 30 days.
