Psychosis

Anorexia
* ask about eating habits, appeptite, have the lost weight, are they satisfied with their current weight, do they think they are eating enough

23
Q

Abbreviated mental test score (AMTS) is a 10-point assessment …what questions

A
  1. “What is your age?”
  2. “What is the time to the nearest hour?”
  3. Give the patient an address, and ask them to repeat it at the end of the test (e.g. “42 West Street”)
  4. “What is the year?”
  5. “What is the name of this place?” or “What is your house number?”
  6. Can the patient recognise two persons (e.g. doctor, nurse)?
  7. “What is your date of birth?” (day and month sufficient)
  8. “In what year did World War 1 begin?”
  9. “Name the present monarch/prime minister/president”
  10. “Count backwards from 20 down to 1”

A score of 6 or less suggests delirium or dementia, although further tests are necessary to confirm the diagnosis.

24
Q

Risks of emergency tranquilisation

A
  • sedatives may mask important signs of underlying illness, eg an intracranial haematoma requiring urgent treatment.
  • Normal protective reflexes (including airway reflexes such as gag and cough response) will be suppressed.
  • Respiratory depression and the need for tracheal intubation and IPPV may develop.
  • Adverse cardiovascular events (eg hypotension and arrhythmias) may be provoked, particularly in a struggling, hypoxic individual
25
Q

oral tranquilisation - oral, name, dose

A
  • Give lorazepam (1–2 mg PO) if there is no psychotic context.
  • Give lorazepam (1–2 mg PO) + antipsychotic (eg haloperidol 1.5–3mg PO) if there is a psychotic context.
26
Q

why use IM rapid tranquilisation? what are options (name of drugs only)

A
  • If PO therapy is inappropriate (refused, failed, or not indicated)
  • choose between IM lorazepam OR IM haloperidol + promethazine.

In most instances, IM lorazepam is the most appropriate first choice

27
Q

IM rapid tranquilisation: drug names and dose

A
  • Give lorazepam (2–4 mg IM) and allow sufficient time for it to work.

Consider giving a further dose of IM lorazepam if there is a partial response, but if there is no response:

  • consider IM haloperidol (5–10mg) + IM promethazine hydrochloride (25–50mg) .
28
Q

In who should you not use IM haloperidol + promethazine for rapid tranquilisation?

A

If there is any history of cardiovascular disease (including long QTc) or if there is no normal ECG recorded.

Pts with parkinsons

29
Q

What monitoring after IM tranquilisation?

A

Record vital signs e.g. HR, BP, RR every 15min if the patient:

  • Is asleep/sedated.
  • Has taken illicit drugs or alcohol.
  • Has any pre-existing physical health problem.
  • Has experienced any injury from restrictive intervention.
  • If the BNF’s maximum dose has been exceeded.
30
Q

Stepped approach for rapid tranquilisation for acutely disturbed or violent pts..

A
  1. Verbal and situational descalation
  2. Offer oral treatment
  3. ir oral refused / ineffective and pt is putting themselves or others at risk - IM treatment
31
Q

What to have on hand if using benzodiazepines for sedation?

A

Flumazenil - in case of respiratory depression.

32
Q

A patient wants to leave before they are assessed by a mental health professional…what to do…..

OX handbook

A
  • try to persuade them to stay.
  • If they refuse, consider their capacity to decide to leave under the MCA framework and whether you can use this to keep them from leaving, or consider
    detaining them under common law, pending an urgent psychiatric assessment.
  • If you are satisfied that the ongoing risk is not of a magnitude that requires them to be detained, then
    allow them to be discharged, but ensure that the GP is informed.
33
Q

The mental health act allows for what treatment…

A

the Mental Health Act only allows treatment for mental health disorders against the wishes of
patients, and not physical health problems.

34
Q

What to remember if you want to treat a patient without their consent?

A
  • You are assessing capacity for a specific decision (e.g. does the patient have capacity to refuse NAC
    treatment for paracetamol OD?). there is no overall/global capacity which a patient has or lacks.
  • Patients may have the capacity to make some decisions and not others.
  • Capacity in the same patient may 􀂀uctuate over time.
  • Disagreeing with medical advice does not automatically constitute incapacity.
  • If a patient does not have capacity and requires emergency treatment, then this may be given against their will under the Mental Capacity Act 2005 or under common law, depending on which is more appropriate.
35
Q

5 principals of mental capacity act?

A
  1. A person must be assumed to have capacity, unless it is established that he lacks capacity.
  2. A person is not to be treated as unable to make a decision, unless all practicable steps to help him to do so have been taken without success.
  3. A person is not to be treated as unable to make a decision merely because he makes an unwise decision.
  4. An act done, or decision made, under this Act for, or on behalf of, a person who lacks capacity must be
    done, or made, in his best interests.
  5. Before the act is done, or the decision is made, regard must be had to whether the purpose for which it is needed can be done in the least restrictive way.
36
Q

Following an episode of self-harm/ overdose, a rapid initial assessment (triage) to establish the degree of urgency of the situation is done.

NICE recommends the Australian Mental Health Triage Scale… a combined physical and mental health triage scale….can think of points on it?

A
37
Q

What domains should you focus on when assessing a pt with self harm?

A

Involve family/carers with the patient’s consent.
Focus upon:
* Events and circumstances leading up to the episode of self-harm.

  • Preparation, concealment, and true intention of a self-harm act.
  • Outcome of the act (eg unintended danger or accidental discovery).
  • Current stresses and financial, legal, or interpersonal problems.
  • Alcohol or substance misuse.
  • Previous self-harm or psychiatric illness.
38
Q

How to decide when to refer for self harm?

Ox handbook of emergency medicine

A
  • Use assessment (earlier card)
  • if in doubt - refer
  • immediately refer child / adolescent
  • Some EDs- patients who are not at immediate risk can come back the next day for an appt with a psychiatric liaison nurse/specialist for psychosocial assessment
  • Ensure that the patient’s GP receives written communication about the patient’s ED attendance and discharge.
39
Q

Factors suggesting suicidal intent

A

Careful preparation (eg saving tablets) and/or significant premeditation.

Final acts (eg organizing finances, insurance, or a will).

Performing self-harm alone, secretly, or when unlikely to be discovered.
