Seclusion decision, least-restrictive ladder and reduction frameworks (MEQ)

(i) Definitions. Seclusion is involuntary confinement of a person alone in a room/area from which free exit is prevented. It is not voluntary use of a quiet or sensory room with free exit, and not merely unit-level environmental locking of ward doors (environmental restriction). Physical restraint is manual force restricting movement; mechanical restraint uses devices; chemical restraint is a contested term for medication used primarily to control behaviour/restrict freedom rather than treat illness — definitions vary and must be stated.^[5]

(ii) Least-restrictive sequence. Ensure scene safety and remove audience/weapons; ABCDE including glucose and SpO2; one lead communicator continues de-escalation with space and clear limits; re-offer oral medication if safe; call trained response team. Physical intervention only if imminent serious harm persists; trained holds; protect airway; avoid prolonged prone; shortest duration. Seclusion only if still required for safety after less restrictive options fail or are unsafe; state exit criteria at initiation; continuous/frequent observation; hydrate and preserve dignity; medical review. Start/continue definitive treatment of psychosis once safe. Document alternatives tried, legal basis under local policy/statute (no invented sections), times, staff, injuries.^[5][6]

(iii) Harms and positional safety. Chieze et al. systematic review documents significant adverse physical and psychological effects of seclusion and restraint; last-resort framing with safeguards. Cochrane (Sailas and Fenton) found insufficient RCT evidence of therapeutic benefit. Positional rules: continuous observation; protect chest expansion and airway; avoid prolonged prone and torso-loading; monitor for distress, cyanosis, reduced responsiveness; post-event injury and physiology check (consider CK after severe struggle).^[1][2][5]

(iv) Reduction frameworks and aftercare. Six Core Strategies (Huckshorn): leadership; data; workforce development; prevention tools; consumer roles; debriefing. Safewards (Bowers): model and cluster RCT showing reduced conflict and containment with ward interventions. After episode: patient debrief (process, fairness, repair alliance); staff debrief and learning; revise care plan/triggers; governance data entry; senior review if prolonged.^[3][4][7]

(v) Overnight seclusion and 'chemical restraint' language. Refuse seclusion 'for the night so the ward can settle' — duration is driven by ongoing imminence of harm and exit criteria, not roster convenience; prolonged seclusion without continuous review is a failure signal. For medication: chart with a therapeutic indication (e.g. protocolised rapid tranquillisation for severe agitation/psychosis), agent, dose, route, monitoring — not as indefinite chemical silencing. If force is used, explain purpose, minimise, and review. Coercion process quality matters to later engagement.^[1][5][7]
