Family Medicine
Family medicine in the HKCFP Conjoint MCQ tests applied primary-care reasoning rather than isolated disease facts. You are expected to manage common, undifferentiated and multimorbid problems over time, using the patient’s family, community and preferences as clinical data. The section rewards safe, proportionate decisions: what to do now, what to investigate, what to safety-net, and when to refer.
Core rules and concepts
- Think probabilistically. In primary care, serious disease is uncommon but not excluded; use prevalence, red flags and time to refine the working diagnosis.
- Use a biopsychosocial and patient-centred frame. Symptoms are often explained by combined physical, psychological and social factors; ask about beliefs, mood, family and work.
- Manage multimorbidity, not single diseases. Check whether guidelines conflict, prioritise patient goals, and review polypharmacy and adherence.
- Apply prevention selectively: screening, vaccination and lifestyle advice should fit the patient’s risk and preferences; avoid overdiagnosis.
- Prescribe and refer with thresholds. Consider adverse drug effects, renal/hepatic function, interactions, cost and follow-up.
Worked example
A 62-year-old man with type 2 diabetes, hypertension and obesity presents with two weeks of fatigue. His HbA1c is 8.1%, blood pressure 146/88, and he takes metformin, ramipril and atorvastatin. The exam-style reasoning is not to label this “poor diabetes control”. First screen for red flags: weight loss, fever, night sweats, chest pain, dyspnoea, bowel change and suicidal ideation. Then review possible causes: metformin-associated B12 deficiency, ramipril-related renal impairment, statin myalgia, sleep apnoea, depression and psychosocial stress. Initial tests might include CBC, renal function, electrolytes, HbA1c, TSH, liver enzymes and urine albumin-creatinine ratio, guided by findings. Management includes medication review, adherence support, mental-health screening, sleep assessment and explicit safety-netting. Referral is triggered by red flags, unexplained abnormal results or failed primary-care management.
Traps
- Anchoring on a known chronic disease and missing a new serious diagnosis.
- Over-investigating low-risk symptoms while under-investigating red flags.
- Giving guideline-driven treatment that ignores frailty, cost or patient preference.
- Forgetting drug causes and interactions in polypharmacy.
- Failing to document safety-netting and follow-up.
