What will we cover
Evidence for and against “medically clear”
An interesting case
Where to from here?
![Page 3: Medical clearance of the psychiatric patient](https://reader036.vdocuments.mx/reader036/viewer/2022062303/55864881d8b42af76a8b456c/html5/thumbnails/3.jpg)
What is medically clear?
An ambiguous termNo medical issues (18yo with depression)
Concomitant medical issues with psychiatric issues dominating (34yo poorly controlled diabetic with depression)
Recently medically unwell but now suitable for management in a psychiatric facility (18yo post paracetamol OD now completed NAC)
![Page 4: Medical clearance of the psychiatric patient](https://reader036.vdocuments.mx/reader036/viewer/2022062303/55864881d8b42af76a8b456c/html5/thumbnails/4.jpg)
What is medically clear?
The patient as currently assessed is medically suitable for management in a psychiatric facility
Less ability to manage complicated illness
Some but less access to comprehensive medical care
Not a guarantee that there is no medical illness
Not a guarantee that there is no risk of a subsequent medical illness
![Page 5: Medical clearance of the psychiatric patient](https://reader036.vdocuments.mx/reader036/viewer/2022062303/55864881d8b42af76a8b456c/html5/thumbnails/5.jpg)
How do we declare a patient medically clear
Don’t forget the basic stuff
History including a basic psychiatric history
Examination including a basic mental state exam
Observations
Investigation if indicated
![Page 6: Medical clearance of the psychiatric patient](https://reader036.vdocuments.mx/reader036/viewer/2022062303/55864881d8b42af76a8b456c/html5/thumbnails/6.jpg)
Investigation
Every test in the PathWest armamentarium?
Consider low/higher risk patient groups:Low: Young (18-55), no medical complaints, no new psychiatric or physical complaints, no evidence of drug/alcohol abuse
Higher: Not low.Specifically: atypical features on history, examination abnormalities, substance misuse
![Page 7: Medical clearance of the psychiatric patient](https://reader036.vdocuments.mx/reader036/viewer/2022062303/55864881d8b42af76a8b456c/html5/thumbnails/7.jpg)
Low risk patients
Often need no further investigation other than thorough history, examination, observations
Is there good evidence for “routine bloods”?
There are multiple studies suggesting this is unnecessary

Higher risk patients
FBC, UE, urine seem to be the very minimum
Consider others:LFT
Drug levels
CK/CRP/CXR
CT Head/LP/EEG
Inpatient consultation

An interesting case

25yo female BIBA with altered mental state at 9am Monday morning

Today had bizarre behaviour – defecated on floor of bathroom, repeating “mum, mum, mum, mum”
Mum called SJA who bring patient here

HR 100, BP 130/80, SpO2 99, T 36.5
Pupils 8mm, no other neurology
Watching people move around but mute/refusing to talk
What now?
![Page 12: Medical clearance of the psychiatric patient](https://reader036.vdocuments.mx/reader036/viewer/2022062303/55864881d8b42af76a8b456c/html5/thumbnails/12.jpg)
Midazolam 2.5mg
HR lowered, pupils stayed same
“Help me get off of stilnox”
10mg diazepam orally
Mum presents, and gives additional collateral historyTwo previous episodes of this both managed at Joondalup
One of these settled spontaneously after 48 hours when mum touched her on the lips
![Page 13: Medical clearance of the psychiatric patient](https://reader036.vdocuments.mx/reader036/viewer/2022062303/55864881d8b42af76a8b456c/html5/thumbnails/13.jpg)
Decision to manage as zolpidem withdrawal
On review about 3 hours later patient watching people move around but mute again, shutting mouth to people trying to give her diazepam as per WC
What now?

DDx:Functional
BZD withdrawal
Functional
Plan:Admit obs as zolpidem/BZD withdrawal
I expect she will improve overnight with observation

Morning after:Similar midazolam responsive odd behaviour
CT brain
Referred to neurology
Neurology reviewed
EEG – diffuse epileptiform activity

Z drugs
GABAergic sedative/hypnotics with minimal anxiolytic effect
Similar profile to short acting BZDs
Specific adverse effects:Complex parasomnias
Reports of hallucinations and psychosis, potentially not related to dose rate
Interactions with other psychotropics have precipitated hallucinations
![Page 20: Medical clearance of the psychiatric patient](https://reader036.vdocuments.mx/reader036/viewer/2022062303/55864881d8b42af76a8b456c/html5/thumbnails/20.jpg)
Non-convulsive status epilepticus
Case reports exist of non-convulsive seizures in the context of BZD withdrawal
Case reports exist of seizures in the context of sudden zolpidem withdrawal

Where to from here?
Documenting medical clearance and what we specifically mean is important
Each institution can potentially have different requirements
For example:

Bankstown Hospital EDPHYSICAL HEALTH REVIEW FOR MENTAL HEALTH PATIENTS
Brief description of presenting problem:
Physiological Observations:Heart rate BP Temp Resp. rate O2Sats
Any acute physical health problems (including ingestion or drug side-effects) ?
Is the patient excessively drowsy or confused?(distinguish confusion from psychosis)
Can you find any evidence of physical cause for the acute presentation?
Are there any issues that the psychiatry team should follow-up?

Any questions?
