History Taking Flashcards

1
Q

What are the typical history taking tasks?

A

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

Q

What are the elements of health advocacy that are assessed?

A
  • 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

Q

What are some tips for history taking?

A
  • 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

A

History
1- Explore reason/circumstances of presentation

Q

Delirium history approach and workup priorities?

A

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
- Paracetamol, salicylates, digoxin
- Psychotropics, anticonvulsants
- Diuretics
*Infectious cause
- Meningoencephalitis
- Other infections
Electrolyte derangment
- Hyponatraemia most common
- Hypernatraemia, hypercalcaemia
Metabolic/Endocrine derangment
- DKA, HHS, Uraemia, Azotaemia
- Hyper/hypothyroid
*Organ damage
- MI, PE, CCF, AKI, liver failure

Scoring Systems
MMSE
- for both delerium and dementia
- Score out of 30, needs pen and paper
- 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

Q

Depression History approach?

A

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
A- Appetite disturbance or weight loss
P- Psychomotor alteration

Q

How should a chest pain history be approached?

A

Life threats
- AMI with cardiogenic shock
- Thoracic aortic dissection
- Rupturing AAA
- Pulmonary embolism
- Pneumonia
- Perforated duodenal ulcer
- Upper GI abdominal catastrophe

Red flags
- Tearing/ripping pain
- Sudden onset
-

History
- PERC/Wells/ADDRS

ECG’s
- Repeat ECG’s!!!
- Look at OLD ECG’s!!!

Investigations
- Blood gas
- Bedside CXR
- Bedside echo
- Trop and screening bloods
- Bilateral blood pressures
- radial-radial/femoral delay

Modified HEART score
- Prospectively validated in ED settings, modified has removed the troponin (ie for use before tests)
- Better validation than EDACS and not retrospective like TIMI score
H- History, high suspicion (typical symptoms) = 2 points
- Moderate suspicion (mixed atypical and typical) = 1 points
- Minimal/no suspicion (very atypical) = 0 points
E- ECG, STD = 2 points, non-specific changes = 1 point, normal = 0 points
A- Age <45 = 0 points, 45-64 = 1 point and >65 = 2 points
R- Risk factors, no RF’s = 0 points, 1-2 = 1 point, 3 or more = 2 points
- High risk if 4 or more points
T- Troponin, taken out of the modified score
- 0 points if no rise, slight to 3x rise = 1 point and >3x rise = 2 points
- Often patients with elevated troponins will be admitted anyway regardless of risk stratification

Low risk
- Discharge
- No objective testing required

Intermediate risk
- Serial ECG and troponins (3hrly)
- 2nd tropnin at at least 6hrs post pain starting
- Screen for other causes
- If normal then discharge with objective testing ie stress test

High risk
- Admit under cardiology
- DAPT +/- further therapy
