In order to reduce inpatient suicide, ligature resistance has been a focus of CMS and accrediting organizations for the past several years, but questions remain as to how far we go and where the real risks lie. In this study based in the Veterans Administration, researchers conducted a retrospective review and analysis of system-wide data of suicide deaths and attempts. As with other studies, the majority of suicides or attempts involved hanging, most of which used doors as the anchor point. Of events where the patient was using a door, more than a third involved an over-the-door alarm (OTD), and none of those events included a death. While correlation does not prove causation, the results suggest that OTD alarms prevented death. Knowing the alarm might alert staff became part of the deterrent. Quite simply, in mental health units where the risk of patients committing suicide is high, OTD alarms may help save lives, as part of a comprehensive strategy that includes sight lines, rounding, ongoing maintenance, and even ligature resistant bedding.
