Restrictive Interventions Carry Significant Mortality Risk and Psychological Harm
Restraints and seclusion can be lethal: more than 24 patients died from restraint- or seclusion-related deaths in 1998 alone, with 111 deaths reported over a 10-year period in New York facilities, and 45 deaths among child and adolescent psychiatric facilities between 1993 and 2003 1, 2.
Documented Physical Harms
The evidence demonstrates serious physical complications from restrictive interventions:
Fatal complications include:
- Cardiac arrest from chest compression (most common mechanism)
- Strangulation from vest restraints or improper positioning
- Pulmonary embolism
- Rhabdomyolysis leading to cardiac arrest (particularly dangerous with stimulant-induced agitation) 2, 3
Non-fatal but serious complications occur with concerning frequency:
- Skin breakdown at restraint sites (most common)
- Venous thromboembolism (occurs even with prophylaxis during mechanical restraint)
- Neurovascular damage and brachial plexus injuries
- Injuries during physical restraint application (0.8-4% of cases)
- Hyperthermia, electrolyte abnormalities, deep vein thrombosis
- Asphyxia from prone positioning or airway obstruction 2, 3
Psychological and Emotional Trauma
The development or reactivation of posttraumatic stress disorder with flashbacks, nightmares, and intrusive thoughts is a documented consequence of seclusion and restraint, particularly when carried out coercively 1. Patients consistently describe these interventions as:
The psychological harm extends beyond the restrained individual—even patients who merely observe others being restrained report very negative feelings about these practices 6.
Critical Context and Regulatory Response
The severity of these harms prompted federal regulatory action. The Health Care Financing Administration (now CMS) established that patients have the right to be free from restraint or seclusion used as coercion, discipline, or staff convenience, limiting use strictly to emergency situations when less restrictive interventions have failed 1.
A crucial caveat: The guidelines emphasize that seclusion is medically safer than restraint and preserves greater patient autonomy, making it the preferred option when containment becomes necessary 1. However, both should be viewed as emergency security measures—not therapeutic interventions—and used only as last resort 2.
The Evidence Gap Problem
Despite documented harms, there is a significant lack of systematic data on the incidence of adverse events related to coercive interventions 3. Physical adverse events during seclusion appear highly underresearched, and there is no empirical evidence supporting the effectiveness of these interventions for treating violent or unruly behavior 6.
The research base consists primarily of case reports, case series, and quality improvement projects rather than controlled studies 3, 7. This creates a troubling situation where practices with documented mortality continue despite limited evidence of benefit.
Prevention Imperatives
Given the documented mortality and morbidity, the evidence strongly supports:
- Proper staff training on alternatives and correct application techniques
- Continuous monitoring of restrained patients (every 15 minutes minimum for vital signs, injury assessment, circulation, and psychological status)
- Supine positioning with head elevated when restraint is unavoidable
- Avoiding prone positioning whenever possible; if used, monitoring for airway obstruction and minimizing neck/back pressure
- Physician evaluation within 1 hour of restraint initiation 2
The fundamental principle: These interventions should be used less arbitrarily, less frequently, and with less trauma, with the ultimate goal of elimination through prevention-focused approaches that address aggression management before crisis escalation 1, 6, 8.
