Updated Nov 13, 2026 ## Key points - Safety first: assess suicide and self-harm risk and build a crisis plan with triggers, coping strategies and people to contact. - Clear limits and boundaries, set early and enforced the same way by every team member. - Splitting: alternating idealisation and devaluation of staff; answer with one consistent team message. - Treat self-inflicted wounds per policy in a neutral, matter-of-fact way. - De-escalate early: calm voice, active listening, options, space, no arguing or judging. - For intense emotions, teach fast calming skills: cold water on the face and paced breathing with a long exhale. ## What it is In hospital, people with personality disorders, most often borderline personality disorder, are usually admitted for suicidal ideation, self-harm, severe depression or anxiety. Care focuses on safety, a crisis or safety plan, clear limits and boundaries set by the whole team, early de-escalation and coping skills. Relationships may swing between idealising and devaluing people (splitting), so the same message from every staff member protects both the person and the team. Psychotherapy, such as dialectical behaviour therapy, is the first-line treatment. ## What it requires - A written care plan with the agreed limits and consequences, known to all shifts. - Shared communication across shifts so the whole team applies a single approach. - A safety plan in the person's own words. - A response to self-harm agreed in advance, according to agency policy. ## Components - Safety: suicide, self-harm and aggression. - Structure: limits, boundaries and team consistency. - Relationship: empathy without over-involvement, neutral responses. - Skills: coping, emotion regulation, link to psychotherapy. ## How it is applied (and why) - Assess suicide and self-harm risk and agree a crisis plan: risky thoughts, triggers, coping steps and people to call — the plan makes help concrete. - State limits and expectations clearly, early and in writing, and review them calmly when problems appear — clear structure reduces testing of limits. - Give the same answer as the rest of the team and discuss any attempt to set staff against each other — consistency counters splitting. - If self-harm occurs, give wound care per policy in a neutral, matter-of-fact way — a calm response meets the need for care without reinforcing it. - Ask the person to write the sequence of events and consequences before discussing them — this helps them see triggers and choices. - At early signs of agitation, speak calmly, listen, offer options, keep space and do not touch without permission — early de-escalation prevents restriction. - Teach quick calming skills, such as ice-cold water on the face and breathing with a long exhale — they act fast on intense emotions. - Support the psychotherapy plan and link to follow-up, and give crisis contacts at discharge (in Colombia, line 106) — psychotherapy is first-line treatment. ## In nursing practice - No medicine is specifically approved for personality disorders; medicines may treat specific symptoms. - Personality disorder diagnoses are generally not made before late adolescence. - Behaviours labelled «manipulative» are addressed therapeutically, not with punishment or rejection. - Mood can shift within hours; reassess risk often. ## Common mistakes - Making special exceptions for one person or shift. - Reacting to self-harm with anger or excessive attention. - Arguing with the person or making judgemental comments. - Discharging without a crisis plan. ## Test yourself Think of the answer, then tap the question to see it. ## What is splitting and how should the team respond? Alternating between idealising and devaluing people; the team responds with one consistent message and the same limits from every member. ## How should a nurse respond to superficial self-injury? Follow agency policy and dress the wound in a neutral, matter-of-fact manner, then review the events and triggers with the person. ## Which quick techniques can calm intense emotion? Applying ice-cold water to the face and paced breathing in which the exhale is longer than the inhale.
