Safe De-escalation Skills for the Agitated Patient: Lessons from HM17

Hospital corridors in Sydney, Melbourne and Perth are growing busier each year, and the people who arrive in distress are no longer only those with a primary psychiatric diagnosis. Drug and alcohol intoxication, dementia, delirium after surgery, and the acute stress of a new cancer diagnosis can all tip a patient into agitation. Australian clinicians attending Hospital Medicine 2017 in Las Vegas were reminded that the first line of care is rarely a syringe or a restraint — it is the quality of the human encounter.

The session drew on practical experience from the United States and applied it to the realities of the local healthcare system, where public hospital funding flows through Medicare, the Pharmaceutical Benefits Scheme shapes what can be dispensed cheaply at discharge, and state Mental Health Acts set the legal limits on restrictive practices. What follows are the core skills and systems thinking shared at this year's conference hub in a way that frontline teams in Brisbane, Adelaide and beyond can adopt on Monday morning.

Why Agitation Demands a Calm, Trained Response

An agitated patient is not, in the first instance, a behaviour problem. It is a clinical signal that something has overwhelmed the person's capacity to cope — pain, hypoxia, fear, withdrawal, or an unfamiliar environment after a transfer from a small rural hospital to a tertiary centre in Canberra. The HM17 faculty stressed that the physiological fight-or-flight cascade narrows cognition, raises heart rate, and reduces the ability to process language. That is why shouting back rarely works and why a predictable, low-arousal presence does.

Australian data from the Australian Institute of Health and Welfare show that seclusion and mechanical restraint events remain a measurable quality-and-safety indicator, and hospitals are expected to report and review them. Treating every code black as a system learning opportunity, rather than a personal failure, protects both the patient and the staff member who, at 3 am in a Townsville ED, has had no training in trauma-informed care since medical school.

Recognising the Warning Signs Early

De-escalation that begins at the door is far more effective than de-escalation that begins after security has been called. Presenters at HM17 described a simple bedside check: tone of voice rising above conversational level, pacing or invading personal space, clenched fists, and a fixed stare. Australian hospitalists who work in busy mixed EDs in Western Sydney or the Royal Melbourne noted that these cues often appear 20 to 30 minutes before the first verbal threat.

Equally important is the team huddle. A quick word with the nurse, the wardsperson, and the security officer before entering the room — sharing what triggered the behaviour, what language to use, and what the exit looks like — is now considered standard practice in many NSW Local Health Districts. The principle is borrowed from aviation crew resource management and translated for the ward round.

Verbal De-escalation: The Core Toolbox

The words chosen in the first 60 seconds tend to set the trajectory of the next six hours. The HM17 workshop used the mnemonic CLEAR — Calm, Listen, Empathise, Agree, Redirect. The Calm step is as much about breathing rate as vocabulary; an Australian nurse educator in Hobart demonstrated how a slowed exhale signals safety to the limbic system. Listen means allowing seven to ten seconds of silence after the patient speaks, rather than rushing to reassure.

Empathise is not the same as agree, and presenters were firm on that point. Validating the feeling — "I can see this is frightening" — does not require endorsing a demand to leave against medical advice. Redirect is the gentle pivot toward a workable next step, such as offering water, a quieter space away from the fluorescent glare, or a phone call to a relative. The wider evidence base from the conference, including recent HM17 clinical updates, repeatedly stressed that staff who feel psychologically safe themselves deliver calmer care.

Environmental and Team-Based Strategies

The physical environment matters more than many clinicians realise. Australian inpatient units designed in the 1990s often have noxious acoustics, with hard surfaces, central nursing stations, and fluorescent lighting that flickers in a way some patients with migraine or early dementia find intolerable. HM17 speakers recommended low-cost changes — soft lighting in the high-risk bay, removing loose objects that could be thrown, and ensuring the patient can see the door rather than feel cornered.

Team composition is the second lever. A consistent bedside nurse who has completed the local aggression-management training is more valuable than a rotating roster of unfamiliar faces. Where feasible, embedding a lived-experience peer worker alongside the medical team, an approach now funded in parts of Queensland and Victoria, has been shown to shorten agitation episodes. The team also needs a clear post-event debrief, which Australian hospitals are increasingly structuring around the Second Victim phenomenon described by Albert Wu.

When to Use Medication — and When Not To

Pharmacological restraint has its place, but it is rarely the first option and almost never the best option. The conference framing was blunt: if a verbal and environmental strategy could have worked, medication represents a system failure to deploy those strategies in time. When medication is genuinely required — for severe distress with imminent risk — low-dose oral or buccal agents such as olanzapine or lorazepam are preferred over deep intramuscular sedation whenever the patient will accept them.

PBS prescribing rules in Australia shape what is realistically available on the ward. Olanzapine wafers, for instance, are listed but require careful documentation under the authority system, and droperidol has specific TGA scheduling that limits where it can be stored. Clinicians were reminded to check the patient's medication chart for anticholinergic load, since older patients in particular — the 78-year-old in a Perth geriatric ward who became distressed after a UTI — can worsen into delirium with overly sedating combinations.

Documentation, Restraint, and Australian Legal Duties

Every episode of agitation, every de-escalation attempt, and every use of restrictive practice must be documented in language that would survive an AHPRA notification or a coronial inquiry. The HM17 presenters recommended a structured note that records the trigger, the patient's own words in quotation marks, the techniques attempted, the response, and the rationale for any pharmacological intervention. This is not bureaucratic overhead; it is the chart that the next on-call doctor will read at 2 am when the cycle begins again.

State legislation frames the boundaries. The NSW Mental Health Act 2007 and the Victorian Mental Health Act 2014 both define "restrictive intervention" narrowly and require treatment in the least restrictive setting consistent with safety. In Queensland, the Mental Health Act 2016 explicitly favours oral medication over injected forms where the person will accept it. Hospitals that fall short of these standards face scrutiny from the Chief Psychiatrist and, increasingly, from the Aged Care Quality and Safety Commission when the patient is an older person under shared care.

Building a Hospital-Wide Culture of Safety

Skill decay is real, and a one-off workshop fades within six months unless it is reinforced. HM17 speakers highlighted three sustainability pillars — annual simulation, visible executive sponsorship, and a non-punitive review of every code black. Several Australian networks, including the Sydney Children's Hospitals Network and parts of the Western Australia Department of Health, have adopted the Safewards model originally developed in the UK, which has measurably reduced conflict and containment events.

Culture also means how staff are treated. An agitated patient can leave a nurse shaken, and a registrar in a Darwin ED may not have slept for 30 hours. Peer support programs, easily accessed debriefs, and clear escalation pathways for staff who feel unsafe after an incident are now considered as essential as the clinical protocol itself. The benchmark of a mature unit is whether the team can talk openly about the patient encounter without blame.

Practical Recommendations for the Australian Ward

• Run a 10-minute pre-shift huddle on the high-risk bay, with nursing, medical and security staff agreeing on the de-escalation plan.
• Display the CLEAR mnemonic at the bedside of any patient flagged as at risk, alongside the patient's preferred name and the contact details of a relative or carer.
• Audit the last 10 code black events on your ward for the time from trigger to first verbal response, and share the median with the team.
• Stock buccal or wafer antipsychotics on the resuscitation trolley so the least restrictive route is the easiest route.
• Schedule quarterly simulation sessions co-led by a psychiatrist, an ED nurse and a peer worker with lived experience.
• Review the ward environment for glare, noise, and sight-lines from the bed to the door, and act on the cheapest fixes within a fortnight.

A useful next step for any hospitalist reading this is to spend the next ward round at the bedside of one patient flagged as at risk of agitation and ask the nursing team, out loud, what their de-escalation plan is — then write it in the notes so the night team inherits a shared language rather than a fresh start.
