Cultural Competence and Indigenous Health — DCE Clinical Case

Station scenario

Setting. General medical ward of a metropolitan teaching hospital, 800 km from the patient's remote community. [1]

Patient. Mrs K is a 48-year-old Aboriginal woman from a remote community in the Northern Territory, admitted overnight with a 5-day history of progressive breathlessness, orthopnoea and bilateral leg swelling. [1]

Admission data.

• Blood pressure 104/68, heart rate 112 and irregularly irregular (atrial fibrillation), respiratory rate 24, oxygen saturation 90 per cent on room air
• Bilateral basal crackles, raised JVP, bipedal oedema
• Echocardiogram: severe rheumatic mitral stenosis (valve area 0.9 cm2), moderate mitral regurgitation, mild aortic regurgitation, left atrial dilatation, no left atrial thrombus
• HbA1c 84 mmol/mol, eGFR 38, ACR 65 mg/mmol, total cholesterol 5.8
• INR 1.1 (not anticoagulated)
• Chronic right ear discharge on otoscopy with central tympanic membrane perforation
• History of ARF at age 12, on secondary prophylaxis (benzathine penicillin G every 28 days) but has missed 4 of last 6 injections
• 800 km from home, 14-year-old son is her primary carer, no Aboriginal Health Worker has been involved
• Nursing notes describe her as 'non-compliant'
• Known depression, not currently engaged with mental health services [1]

Task. The candidate has 25 minutes to assess the patient, take the history, consider the investigations, formulate a prioritised problem list and an integrated management plan, and be prepared to present to the examiner and answer probing questions. [1]

Candidate assessment

History

The candidate should take a history that includes: [1]

• Presenting complaint and cardiac history: onset and progression of breathlessness, orthopnoea, paroxysmal nocturnal dyspnoea, ankle swelling, palpitations, chest pain, syncope, exercise tolerance
• RHD history: when was ARF diagnosed, what were the symptoms, when was RHD confirmed, what is the current prophylaxis regimen, how many injections has she missed and why, has she had any recurrence of ARF symptoms
• Diabetes and CKD: when was diabetes diagnosed, current medications, last HbA1c, any retinopathy or neuropathy, any foot problems, any symptoms of uraemia
• Ear history: chronic discharge, hearing loss, impact on communication and daily life, previous ENT treatment
• Mental health: depression history, current treatment, any suicidal ideation, substance use
• Social and cultural history: where is she from, who is at home, who cares for her son when she is unwell, what is the housing situation, what is her connection to community, what are her cultural obligations, has she had previous negative experiences in the health system, what does she understand about her illness and what does she want
• Other: medications, allergies, smoking, alcohol, family history (including cardiovascular disease, diabetes, RHD, mental illness) [1]

Examination

The candidate should examine:

• Cardiovascular: the signs of severe mitral stenosis (loud S1, opening snap, mid-diastolic rumble at the apex), the signs of mixed mitral disease and aortic regurgitation, the signs of heart failure (raised JVP, crackles, oedema), the irregularly irregular pulse of atrial fibrillation
• Ear: the chronic perforation and discharge of CSOM, tuning fork tests for conductive hearing loss
• General: the stigmata of chronic disease, signs of anaemia, fluid status, foot examination (diabetic foot risk) [1]

Problem list

1. Decompensated heart failure from severe rheumatic mitral stenosis with atrial fibrillation
2. Suboptimal secondary prophylaxis for RHD (missed 4 of 6 injections, high risk of recurrence)
3. Type 2 diabetes mellitus with poor glycaemic control (HbA1c 84)
4. Diabetic kidney disease stage 3B with albuminuria (eGFR 38, ACR 65)
5. Chronic suppurative otitis media with bilateral conductive hearing loss
6. Depression, under-treated
7. Social and cultural context: isolation from community, adolescent carer, no Aboriginal Health Worker, system disengagement, 800 km from home [1]

Integrated management plan

1. Decompensated heart failure and atrial fibrillation

Immediate: oxygen, intravenous frusemide (titrated to urine output and weight, monitoring electrolytes and renal function given the CKD), rate control for the atrial fibrillation (beta-blocker or digoxin, avoiding calcium channel blockers in heart failure), therapeutic anticoagulation (the patient with mitral stenosis and AF has a very high stroke risk — start warfarin or a DOAC after assessing for contraindications, and check for left atrial thrombus on the transoesophageal echo if valvuloplasty is planned). [1]

Definitive: discuss with the interventional cardiology team for percutaneous balloon mitral valvuloplasty (the valve area is 0.9 cm2 — critical; if the valve morphology is suitable — pliable, no heavy calcification, no left atrial thrombus, no more than moderate MR — valvuloplasty is the treatment of choice) or surgical mitral valve replacement if not suitable. The patient will need lifelong anticoagulation if AF persists or if she has a mechanical valve. [1]

2. Secondary prophylaxis for RHD

Reframe the problem: the missed injections are a system failure, not a patient failure. The candidate must not attribute blame. [1]

Actions: involve the Aboriginal Health Worker and the Liaison Officer; explain the rationale for the injection using teach-back and an interpreter if needed; address the practical barriers (transport, pain management with lignocaine diluent and ice, a consistent nurse, childcare for her son); re-establish the patient on the register and recall system; arrange community-based delivery through the outreach or Aboriginal Medical Service nurse; document the plan and the barriers addressed. [1]

3. Type 2 diabetes

Actions: metformin dose-adjusted for eGFR (500 mg twice daily at eGFR 38); add an SGLT2 inhibitor for renal and cardiovascular protection (dapagliflozin 10 mg daily); consider insulin for the HbA1c of 84 given the long-standing disease and the contraindication to metformin dose escalation at this eGFR; involve the diabetes educator and dietitian; arrange retinal screening (via telehealth fundal photography) and foot examination. [1]

4. Diabetic kidney disease

Actions: ACE inhibitor (or ARB) for albuminuria, titrated to maximum tolerated dose, monitoring potassium and creatinine; statin therapy (high-intensity: atorvastatin 40 to 80 mg); blood pressure target below 130/80; nephrology referral for shared care given the trajectory; begin education about renal replacement therapy options (home peritoneal dialysis, home haemodialysis, facility haemodialysis, transplant) so that the patient can make an informed choice in advance. [1]

5. Chronic suppurative otitis media

Actions: dry mopping (ear toilet); topical antibiotic-steroid drops after ENT assessment (avoiding aminoglycosides where possible because of ototoxicity risk); audiometry to document the hearing loss; ENT referral for consideration of tympanoplasty once the ear is dry; consider amplification (hearing aid) to improve communication during the admission and at home. [1]

6. Depression

Actions: assess severity and suicide risk (using culturally appropriate screening); involve the Indigenous mental health service; consider pharmacotherapy (SSRI, started low and titrated slowly, monitoring for emergent suicidality); arrange follow-up through the community mental health service and the Aboriginal Medical Service. [1]

7. Social and cultural context

Actions: involve the Aboriginal Liaison Officer from the outset; address the hearing loss in all communication (face the patient, speak clearly, use written information, consider amplification); explore the social situation (who is caring for her son, what is the housing situation, what are her community obligations); be aware of Sorry Business and kinship obligations; reframe the team's language from 'non-compliant'; reflect on the team's own assumptions; build a discharge plan that is community-based, coordinated, and realistic. [1]

Communication and shared decision-making

The valvuloplasty or surgery discussion

The candidate should demonstrate the ability to discuss the definitive valve intervention with the patient in a culturally safe way: [1]

• Involve the Aboriginal Liaison Officer and, if the patient wishes, her family
• Explain the procedure, the benefit (relief of symptoms, improved survival), the risks, and the alternative (ongoing medical management with a poor prognosis), in plain language
• Use the teach-back method to confirm understanding
• Respect the patient's right to make the decision collectively with her family if that is her cultural practice
• Give her time and not pressure her
• Document the discussion and the decision [1]

The goals-of-care conversation

The candidate should hold a goals-of-care conversation that respects the patient's priorities: [1]

• Explore what the patient understands about her illness and prognosis
• Ask what is most important to her (going home, being with her son, her community obligations, her cultural practices)
• Share honest information about the outcomes of the options
• Align the medical recommendations with her values
• Propose a plan that is proportionate to the goals and achievable in her context [1]

Discharge plan

The discharge plan must be: [1]

• Community-based: the ongoing care is delivered through the Aboriginal Medical Service, the specialist outreach team, and the community nurse, so that the patient does not have to travel 800 km for routine follow-up
• Culturally safe: the Aboriginal Health Worker is part of the team, the patient's cultural needs are respected, and the plan is explained and confirmed with teach-back
• Realistic: the plan accounts for the distance, the transport barriers, the patient's role as a mother, and the community context
• Coordinated: the plan is documented in the shared care record, communicated to the community-controlled health service, and reviewed with the patient
• Followed up: the patient is contacted within a week of discharge by the Aboriginal Liaison Officer or the community nurse to confirm she is managing and to address any barriers [1]

Examiner discussion questions

Examiner: How does this patient's presentation reflect the broader pattern of Indigenous health disparities? [1]

This patient exemplifies the cumulative burden of disadvantage. At 48, she has severe RHD (a disease virtually eliminated in non-Indigenous Australians), type 2 diabetes with complications, CKD, chronic otitis media from childhood, and depression — all driven by the social determinants (overcrowded housing in childhood that enabled the Strep A transmission that caused her ARF, food insecurity and a Western diet that contributed to her diabetes, limited access to preventive care that allowed the CKD to progress, and the intergenerational trauma and ongoing racism that contribute to her mental illness). The physician who treats each disease in isolation misses the story; the physician who sees the whole patient and the social determinants can intervene at multiple levels. [1]

Examiner: What is the physician's role in Closing the Gap? [1]

The physician contributes to Closing the Gap through every culturally safe, evidence-based, equitable clinical encounter. The diagnosis and management of this patient's RHD (ensuring she receives her prophylaxis, her valvuloplasty, her anticoagulation), her diabetes and CKD (early aggressive management to prevent progression to ESKD), her otitis media (preventing further hearing loss), and her depression — these are the individual clinical acts that, accumulated across the health system and the population, move the Closing the Gap targets. Beyond the individual encounter, the physician advocates for systemic change — for equitable access to specialist outreach, for culturally safe services, for the community-controlled health sector, and for the addressing of the social determinants. [1]

Examiner: How would you respond if the patient said she wanted to leave the hospital and go home? [1]

I would not try to prevent her from leaving, but I would explore why she wants to leave. I would ask about her concerns — is she frightened, in pain, worried about her son, feeling isolated, has someone said something that upset her, does she have community obligations? I would address whatever I could address. I would involve the Aboriginal Liaison Officer. I would explain, honestly and in plain language, what would happen if she left (the heart failure would worsen, the AF would place her at risk of stroke, the diabetes and CKD would progress) and what the treatment could offer. I would respect her decision if she had capacity, but I would ensure she left with a plan — medications, follow-up through the community-controlled health service, and a contact number — and I would arrange for the Aboriginal Liaison Officer or the community nurse to follow up by phone within a few days.
