History Taking Flashcards
What are the typical history taking tasks?
Take a focused history from the patient (role player)
Assess the severity of the condition based on discussion with patient/parent
Counsel the patient as to the possible causes for his/her presentation
Formulate an appropriate diagnostic workup or management/disposition/follow-up plan and communicate this to the patient
Answer the examiner’s questions regarding the differential diagnosis and further patient assessment.
Outline to the examiner the focused history you would obtain in order to diagnose a condition e.g. clinically clear the cervical spine
Give your differential diagnosis and clinical examination approach to the examiner
What are the elements of health advocacy that are assessed?
- Facilitates an adequate follow up plan
- Incorporates the patient’s chronic clinical state and their wishes when making decisions
- Implements strategies to prevent a patient ceasing their emergency care prematurely
- Provides understandable instructions for the patient on discharge, including likely progression of their clinical course, and reasons to return
- Explains to patients and/or their guardians the rationale for management decisions
- Integrates communication skills relevant to the patient’s culture to enhance delivery of health advice to patients
- Refugee Health - Identifies findings on assessment that increase the likelihood of a patient being vulnerable
- Tailors treatment and disposition decisions for a patient to account for the presence of vulnerability factors
What are some tips for history taking?
- The social history should always be explored as it often impacts the discharge advice and possible underlying cause of complaint
- Address all the tasks of the station (ie Hx, DDx, Ix and discharge)
- Pay careful attention to the role player, they will only give relevant information
- Apart from the initial open-ended question, used focused questions as the actors won’t volunteer information
Basic Psychiatric history taking? Further investigations
History
1- Explore reason/circumstances of presentation
2- Screen systemic symptoms (fevers, trauma, weight loss, infectious symptoms)
3- Past medical/Psych history
4- Illicit drug (ie meth) and medicine (ie anticholinergics) history
5- Orientation TPP
6- Basic MSE (hallucinations, delusions, homicidal/suicidal etc)
7- Social/forensic/sexual
Ix
- FBE/UEC, CK, LFT’s, ECG
- +/- CTB and CXR
- +/- LP
- +/- septic screen
- +/- drug/toxin panel (ie paracetamol level)
- +/- endocrine panel (ie TSH)
- +/- Bladder scan (ie anticholinergic delerium)
Delirium history approach and workup priorities?
Definition
- Disturbance in attention and awareness
- Develops over short period of time
- Fluctuant
- Not better explained by pre-existing pathology ie dementia, psychiatric disorder, neurocognitive disorder or coma
Causes
Substrate deficiency
- BSL, 02, CO2
- Thiamine, B12
Focal CNS pathology
- Stroke, SAH, tumour, bleed
- Hypertensive crisis
Toxidrome
- anticholinergic

Scoring Systems
MMSE
- for both delerium and dementia

- More for inpatient teams
bCAM
- Designed for ED delirium and concussion screening
- Altered mental status or fluctuating course? (yes = proceeed, no = stop)
- Innatention (name the months backwards from December to July) 2 or more errors then proceeed
- Altered level of consciousness? yes = delerium, no = proceed
- Disorganised thinking? (will a stone float on water? Are there fish in the sea? 1kg weigh more than 2kg? Does a hammer pound a nail? Hold up X fingers with each hand) If any errors then bCAM positive
General Management
Initial- Any specific antidotes and correct life threats ie low 02, hypoglycaemia, ABx etc
1- Admit to medics for further workup and psychiatric input if/when medical issue excluded
2- If patient lacks capacity then should be detained under a duty of care vs mental health act depending on scenario
3- May need 1:1 nursing +/- a nursing special dedicated to them, admit to appropriate area of hospital or ED
4- Specific workup goals ie septic and endocrine screen, CTB/LP etc
Depression History approach?
Suicide risk screening
- Determine if active Plans and the Means
- Previous Attempts
- what is the Lethality of their previous attempts and current plan
- Intoxicated, do they have capacity
- Features of psychosis, command hallucinations etc
- Detain under MHA if concerns about suicide on leaving
SAD PERSONS mnemonic for suicide
- See picture
- 0-4 is low risk
- 5-6 is medium risk
- 7-10 is high risk
SIDGECAPS for Depression
- at least 5 of the following features for > 2weeks needed to diagnose major depressive disorder (MDD
S- Sleep disturbance (insominia, excessive sleep)
I- Interest decreased (ie usual fun activities or interests)
D- Depressed mood/anhedonia
G- Guilt or worthlessness
E- Energy decreased
C- Concentration difficulties

- High risk if 4 or more points
T- Troponin, taken out of the modified score
