Service evaluation of electronic monitoring (GPS tracking) in a medium secure forensic psychiatry setting

In 2010, following a series of high-profile absconding incidents, electronic monitoring (EM) using Global Positioning System technology for patients on leave was trialled as part of a comprehensive protocol for risk management and recovery. We conducted a preliminary evaluation of effect on leave and leave violation. The total number of leave episodes and leave violations over a four-month period prior to the introduction of EM was compared with the totals in two corresponding follow-up periods in the two years after the introduction. Total episodes of leave increased by almost 60%. There was a significant association between year and type of leave episode, with leave episodes after the introduction of EM more likely to be unescorted. Episodes of leave violation reduced in each of the two follow-up periods after introduction of EM. These findings suggest potential benefits for speed of patient recovery, reduced length of stay, reduced costs and public safety.
