How to uncover the hidden agenda: "General malaise" is vague — patients often attend because of a deeper worry (cancer fear, work stress, relationship issue, recent bereavement). After exploring biological symptoms, always ask 「其實你今日嚟睇,最令你擔心嘅係咩嚟㗎?」 — this single question frequently reveals the RFC.

Case Report Form Answer Builder

  • Chief complaint: "General malaise for ___ weeks/months"
  • HPI must capture: onset, duration, progression, associated constitutional symptoms (fever, night sweats, weight loss, appetite), associated system symptoms (SOB, palpitations, bleeding, polyuria, joint pain, mood), aggravating/relieving factors, functional impact, medications (including TCM), relevant PMHx

  • Examples: "Concerned about persistent tiredness affecting work"; "Worried the malaise could indicate a serious illness (e.g., cancer)"; "Requested blood tests to find a cause"
  • How to phrase: State the patient's perspective — why today? Use the patient's own words if possible.

Likely ExamplesExact Wording
Ideas"I think I might be anaemic" / "Maybe I'm too stressed" / "I read online it could be cancer""Patient thinks the malaise may be due to ___ (anaemia / stress / serious illness)"
ConcernsFear of cancer, fear of losing job, worry about burdening family"Patient is worried that the malaise may indicate cancer / a serious underlying condition"
ExpectationsBlood test, referral, sick leave, reassurance"Patient hopes to have blood tests done and to be reassured about the cause"

  • Choose based on the stem — in primary care, the most likely diagnosis for an undifferentiated "general malaise" is often:
    • Depression (if mood/sleep/anhedonia clues present) [4]
    • Iron deficiency anaemia (if pallor/menorrhagia/dietary clue) [10]
    • Viral illness / post-viral fatigue (if recent URTI)
  • Minimum supporting evidence: ≥ 2 positive history features + 1 physical sign (e.g., conjunctival pallor for IDA, flat affect for depression)

DDxOne Key Discriminator
HypothyroidismCold intolerance + weight gain + constipation + bradycardia
Diabetes mellitusPolyuria + polydipsia + weight loss despite normal/↑ appetite
Malignancy (e.g., lymphoma)Unexplained weight loss + night sweats + painless lymphadenopathy

DomainExample
BiologicalAnaemia causing fatigue and reduced exercise tolerance
PsychologicalAnxiety/worry about underlying serious illness; or comorbid depressive symptoms
Social/FunctionalInability to work / reduced work performance / burden on family / social withdrawal

Diagnosis/DDxBest Supporting Physical SignHow to ElicitWhy It Supports
Iron deficiency anaemiaConjunctival pallorPull down lower eyelid, inspect palpebral conjunctivaPallor correlates with Hb < 9-10; classic sign of anaemia [10]
DepressionPsychomotor retardation / flat affectObserve during consultation: speech rate, facial expression, engagementSupports diagnosis of major depressive disorder [4]
HypothyroidismDelayed relaxation of ankle jerks / bradycardiaElicit ankle reflex; measure pulseClassic clinical sign of hypothyroidism
Malignancy / LymphomaPainless, firm lymphadenopathyPalpate cervical, axillary, inguinal LN chains systematically [5]Non-tender, rubbery, matted LN persisting > 2 wks suggests malignancy
CKD / UraemiaPeripheral oedema + café-au-lait skin colourInspect skin colour; press pretibial area for pitting oedema [3]Café-au-lait skin + oedema suggests advanced CKD
Hepatitis / Liver failureJaundice (scleral icterus)Inspect sclerae in natural light [6]Icteric sclerae indicate hyperbilirubinaemia
ThyrotoxicosisFine tremor + tachycardia + lid lagOutstretched hands with paper on top; check resting HR; look for lid lagClassic triad of Graves' / thyrotoxicosis

Top Traps That Lose Marks

  1. Jumping to a diagnosis without exploring ICE — the Case Report Form explicitly marks ICE; many students skip it.
  2. Forgetting to ask about depression — depression is the #1 masquerade for general malaise [4]. If you don't screen mood, you miss the most common diagnosis.
  3. Not asking about TCM / herbal medicine — patients may not volunteer this; you must ask specifically about 中成藥 (tablet form) and 中草藥 (herbal form) [6].
  4. Not asking about drugs — beta-blockers, statins, antihypertensives, and chemotherapy all cause fatigue.
  5. Ignoring red flags — unexplained weight loss, night sweats, persistent fever, new lymphadenopathy → must refer urgently.
  6. Writing "malaise" as the diagnosis — malaise is a symptom, not a diagnosis. Always commit to a specific most likely diagnosis.
  7. Forgetting to safety-net — always tell the patient when to return or go to A&E.

Must-not-miss red flags requiring urgent referral:

  • Unexplained weight loss > 5% in 6 months
  • Persistent fever / night sweats > 2 weeks
  • New painless lymphadenopathy
  • Petechiae / unexplained bruising (pancytopenia)
  • Jaundice + coagulopathy (liver failure)
  • Severe hyponatraemia symptoms (confusion, seizures)

Shortest safe management / safety-net line:

「如果你之後出現發高燒、嘔血、突然好攰企唔穩、或者皮膚變黃,就即刻去急症室。我會安排你驗血,一個星期後覆診睇結果。」


High Yield Summary

What to ASK: Onset/duration, constitutional symptoms (fever/night sweats/weight loss), mood screen (PHQ-2), bleeding, thyroid symptoms, polyuria/polydipsia, drug history (especially TCM), ICE, functional impact, and "Why today?"

What to WRITE: Chief complaint with timeline → HPI with system review findings → ONE RFC in patient's words → ICE explicitly → Most likely Dx with 2+ supporting features → 3 DDx with discriminators → 3 biopsychosocial problems → 1 physical sign with reasoning.

What NOT to MISS: Depression, drugs/TCM, anaemia, hypothyroidism, occult malignancy, and the hidden agenda. Malaise is never the diagnosis — always commit to a specific cause.
