Why Ligature-Resistant?

According to reports gathered in Joint Commission’s Journal from November of 20181, ~70 percent of suicides in hospitals were by a means of hanging. As a response, the Joint Commission and other behavioral health organizations have created reports on this trend and created policies to reduce and prevent the potential for suicides these facilities face with an expressed focus on ligature-resistant areas.

Ligature-resistant hardware in mental and behavioral health spaces is not just recommended but an integral part in scoring well in a Joint Commission certification audit. For instance, the recommendations the Joint Commissions set on Inpatient Psychiatric Units state it is required, “Inpatient psychiatric units, in both psychiatric hospitals and general/acute care settings, must be ligature-resistant…2

Requirements can be found (but are not limited to) the following areas:

  • Patient rooms
  • Transitional areas
  • Common patient care areas

Covering these areas with ligature-resistant products can include a variety of product types focused on everything from servicing doors, door hardware, and door accessories to a number of surrounding functions.

Examining the Suicide Trend

The Center of Disease Prevention and Control (CDC) found in a 2016 report that suicide is the 10th-leading cause of death in the United States3—an alarming statistic. The CDC’s report gets noted in The Joint Commission’s complimentary publication R3 Report | Requirement, Rationale, Reference4 as a provocation to re-evaluate the National Patient Safety Goal (NPSG) to address suicide prevention.

Furthermore, The Joint Commission’s Journal released a report in November of 20181 producing estimates from the collected data of hospitals reporting to the National Violent Death Reporting System (NVDRS) 2014–2015, and The Joint Commission’s Sentinel Event (SE) Database from 2010 to 2017. Data from this report implicates the larger statistical role a door’s ligature points perform in suicides committed by psychiatric patients in behavioral health facilities.

For instance, they identified a ligature fixture point in 106 cases of the 137 inpatient hanging events. The most commonly used fixture point was a door, door handle, or door hinge (53.8%).1 Hanging was the most common method of inpatient suicide in the NVDRS and SE databases, accounting for 70.5% of all inpatient suicide events.

In conclusion, the implications of each of these reports indicate the need for an escalated approach to suicide prevention and the role doors (and ligature-resistance) play in reducing suicide prevention.

Handling Door Hardware and Accessories in Mental and Behavioral Health

Diana Oller, the Executive Director of The Door Switch, spends a great deal of time on the road educating behavior healthcare facilities of what goes into preventing suicides onsite. In an article for Door Security + Safety, Oller writes about the benefits of ligature-resistant hardware in combating patient suicides.

In that article, Oller describes The Door Switch as designed to mitigate ligature points associated with the top-of-the-door and door hinges. The Doors Switch’s standard retrofit application is a full-surface continuous hinge application, meaning can be applied without cutting hinges into the door. Also, the full surface hinge approach allows flexibility for doors currently equipped with 3-butt hinge or full mortise continuous hinge applications.  This factors in a major way when facilities usually maintain the original design by utilizing the existing doors and use retrofit applications to address ligature issues.

The Door Switch’s Over the Door Alarm is available in a double-swing hinge and electrified pivot applications to provide a barrier-resistant application.  Full mortise continuous hinge applications are available. For more details: See The Door Switch.

Ultimately, The Door Switch’s Over the Door Alarm plays a central role in door and door hardware ligature-resistance—address ligature concerns at the top of the door and at a door’s hinges.

Doors in Mental and Behavioral Health: Fact and Fiction

James M. Hunt, AIA, NCARB is a behavior healthcare facility design consultant with experience as a practicing architect and facility management professional. In Hunt’s 2015 article for the Academy of Architecture for Health (AAH) he assesses suicides committed by use of a ligature point on a patient’s room doors and frames “remain a frequent occurrence” 5 in behavioral healthcare facilities. In response, Hunt hints at the availability of alternative door hardware that address door and door hardware ligature points as viable options to combat these unfortunate occurrences.

“There are safety alternatives available including pressure sensitive or electric eye type devices that mount on door edges, connect to a central alarm system, and sound alarms when they are activated by the presence of an object, such as a ligature.”5

Hunt asks, “Is it acceptable to ignore a known serious hazard just because it’s required by code and ‘everyone else is doing it?’”

Next Steps for Your Mental and Behavioral Health Facility

In conclusion, any department where psychiatric inpatients are being cared for requires a keen eye for the clearing of all possible ligature points and/or are nullified by the best choice of safety-alternative, ligature-resistant hardware and accessories. Contact your local IDN branch to speak with an informed sales team or to schedule a consultation visit from one of our expert sales representatives to determine the best hardware for your facility and situation.

The methods used in the inpatient setting to commit suicide were similar in the two databases (Table 5). Hanging was by far the most common method of inpatient suicide in the NVDRS and SE databases (33 of 46 [71.7%] and 137 of 195 [70.3%], respectively). The location and ligature fixation point for hangings were consistently coded in the SE Database but not in the NVDRS. A total of 99 of 195 (50.8%) sentinel event suicides occurred in the bathroom, 66 (33.8%) in the bedroom, 8 (4.1%) in the closet, 7 (3.6%) in the shower, and 15 (7.7%) in another location.

Within the SE Database, of the 137 inpatient hanging events, a ligature fixture point was identified in 106 cases—a door, door handle, or door hinge was the most commonly used fixture point (53.8%). Hanging was the most common method of inpatient suicide in the NVDRS and SE databases, accounting for 70.5% of all inpatient suicide events. Of the inpatient hanging events, a door, door handle, or door hinge was the most commonly used fixture point (53.8%). Not surprisingly, more than 90% of suicides took place in private spaces such as the bathroom, bedroom, closet, and shower.

    Ligature Risks – Assessing and Mitigating Risk for Suicide and Self-Harm

    What are the Joint Commission expectations for identifying and managing ligature risks in the hospital setting?
    Element of Performance # 1 states “Interior spaces meet the needs of the patient population and are safe and suitable to the care, treatment, and services provided”. Therefore, ligature and self-harm risks must be identified and eliminated.
