Health Literacy and Patient Education in ICU

1. Quick Answer

Health literacy is the capacity to obtain, process, and understand basic health information and services needed to make appropriate health decisions. In ICU, it critically affects informed consent, adherence, communication quality, and outcomes.

Key Statistics:

• 59% of Australian adults have inadequate health literacy (ABS 2006)
• Low health literacy associated with 50% higher mortality (PMID: 17984378)
• 82% of ICU families do not understand key medical terminology (PMID: 10966293)
• Standard ICU consent forms written at Grade 12+ level (require Grade 6-8)

Three Levels of Health Literacy (Nutbeam Model):

• Functional: Basic reading/writing to understand health instructions
• Interactive/Communicative: Extracting and applying information from communication
• Critical: Analyzing and using information to exert greater control over health

Essential ICU Strategies:

1. Assume universal low health literacy - Use plain language with everyone
2. Teach-back method - "Tell me in your own words what we discussed"
3. Chunk and check - Small amounts of information with frequent checks
4. Visual aids - Pictures, diagrams, videos
5. Written materials - Flesch-Kincaid Grade 6-8 level

Indigenous Health Literacy:

• Aboriginal and Torres Strait Islander Australians: 70-75% inadequate health literacy
• Māori: 65% inadequate health literacy
• Require culturally appropriate resources, interpreter services, AHLO involvement

Must-Know Facts:

• REALM: 66-word recognition test (Grade 3-9 assessment, 2-3 minutes)
• S-TOFHLA: Reading and numeracy assessment (7-12 minutes)
• Single-item screening: "How confident are you filling out medical forms by yourself?"
• ICU diaries reduce PTSD by 50% (PMID: 20494556)

2. CICM Exam Focus

What Examiners Expect

Second Part Written (SAQ):

Common SAQ stems:

• "A 72-year-old man with limited English and Grade 6 education requires informed consent for tracheostomy. His wife who is his substitute decision-maker appears overwhelmed. Outline your approach to ensuring valid informed consent."
• "Describe strategies for communicating complex medical information to families with low health literacy in ICU."
• "A family member repeatedly asks the same questions despite multiple explanations. Discuss potential causes and your approach."
• "Outline the development and evaluation of a patient/family information leaflet for ICU."

Expected depth:

• Definition and levels of health literacy (Nutbeam model)
• Australian prevalence data (59% inadequate)
• Assessment tools with practical application
• Communication strategies (teach-back, plain language, visual aids)
• Written materials development (readability formulas)
• Indigenous health literacy considerations
• ICU-specific resources (diaries, information leaflets)

Second Part Hot Case:

Typical presentations:

• Family repeatedly asking same questions (possible low health literacy)
• Elderly patient with complex medication regimen at discharge
• Indigenous family requiring goals of care discussion
• CALD family with interpreter, discussing consent
• Family disagreement potentially related to misunderstanding

Examiners assess:

• Recognition of health literacy as barrier
• Appropriate communication adjustments
• Use of teach-back to confirm understanding
• Involvement of interpreters, AHLO, or Māori Health Services
• Documentation of communication strategies used

Second Part Viva:

Expected discussion areas:

• Nutbeam's three-level model of health literacy
• Australian prevalence and impact on outcomes
• Assessment tools (REALM, S-TOFHLA, single-item screening)
• Communication strategies with evidence base
• Written materials development and readability assessment
• ICU diaries - evidence and implementation
• Indigenous health literacy (Aboriginal, Torres Strait Islander, Māori)

Examiner expectations:

• Demonstrate consultant-level awareness of health literacy
• Cite evidence for communication interventions
• Apply universal precautions approach
• Show cultural safety competency
• Describe quality improvement for institutional materials

Common Mistakes

• Assuming education level equals health literacy
• Using medical jargon without explanation
• Providing too much information at once
• Not using teach-back to confirm understanding
• Forgetting that stress impairs information processing
• Using written materials with inappropriate reading level
• Not involving Aboriginal Hospital Liaison Officers for Indigenous families
• Assuming interpreter alone addresses health literacy barriers
• Failing to document communication strategies and family understanding

3. Key Points

Must-Know Facts

1. 59% of Australian Adults Have Inadequate Health Literacy: Based on the 2006 Australian Bureau of Statistics Adult Literacy and Life Skills Survey; similar rates in NZ (56%). This means the majority of patients and families in ICU have limited ability to process health information (ABS 2006).

2. Nutbeam's Three Levels: Functional (basic reading/writing), Interactive/Communicative (extracting meaning from communication), Critical (analyzing to take action). Most health education targets only functional level (PMID: 10778668).

3. Low Health Literacy Increases Mortality: Systematic reviews demonstrate 50% higher mortality (HR 1.5, 95% CI 1.2-1.8) in patients with inadequate health literacy, independent of education and socioeconomic status (PMID: 17984378, 21714595).

4. Teach-Back Method: "Tell me in your own words..."

• Improves adherence, reduces errors, and is the single most effective communication strategy. Reduces hospital readmissions by 30% (PMID: 12132975).

5. ICU Consent Forms Require Graduate-Level Reading: Average ICU informed consent forms are written at Grade 12-16 level; should be Grade 6-8 maximum. 75% of patients cannot adequately comprehend standard consent forms (PMID: 12795802).

6. Stress Impairs Information Processing: ICU families under acute stress retain only 20-50% of information; repeat key information, use multiple modalities, provide written summaries (PMID: 10966293).

7. Single-Item Screening Works: "How confident are you filling out medical forms by yourself?"

• Single question identifies 83% of patients with inadequate health literacy (sensitivity 54%, specificity 83%) (PMID: 23929108).

8. ICU Diaries Reduce PTSD: Patient diaries written by staff and family during ICU stay reduce PTSD symptoms by 50% and improve psychological recovery (PMID: 20494556).

9. Indigenous Health Literacy Compounded: Aboriginal and Torres Strait Islander (70-75%) and Māori (65%) populations have higher rates of inadequate health literacy, compounded by cultural, linguistic, and historical barriers (PMID: 28041574).

10. Universal Precautions Approach: Assume ALL patients and families have potential health literacy challenges; use plain language and teach-back with everyone - this reduces stigma and ensures no one is missed (AHRQ 2010).

4. Definition & Epidemiology

Definitions

Health Literacy: The cognitive and social skills which determine the motivation and ability of individuals to gain access to, understand, and use information in ways which promote and maintain good health (WHO 2013).

Institute of Medicine Definition: The degree to which individuals have the capacity to obtain, process, and understand basic health information and services needed to make appropriate health decisions.

Australian Commission Definition: The skills, knowledge, motivation and capacity of a person to access, understand, appraise and apply information to make effective decisions about health and health care and take appropriate action.

Nutbeam's Three Levels of Health Literacy:

Organizational Health Literacy: The degree to which organizations enable individuals to find, understand, and use information and services to make health decisions (AHRQ 2020).

Health Numeracy: The degree to which individuals can access, process, interpret, communicate, and act on numerical, quantitative, graphical, biostatistical, and probabilistic health information needed to make effective health decisions.

Epidemiology

International Data:

• 36% of US adults have basic or below-basic health literacy (NAAL 2003)
• 47% of European adults have inadequate health literacy (HLS-EU 2012)
• Health literacy decreases with age (65+: 71% inadequate)
• Strong correlation with socioeconomic status, but not fully explained by education

Australian Data:

New Zealand Data:

• 56% of adults have inadequate health literacy (Adult Literacy Survey 2006)
• Māori: 65% inadequate health literacy
• Pasifika: 75% inadequate health literacy
• Older adults (65+): 71% inadequate

ICU-Specific Data:

Impact on Outcomes:

High-Risk Populations in ICU:

1. Elderly (≥65 years): Cognitive decline, sensory impairments, polypharmacy
2. Aboriginal and Torres Strait Islander: Cultural, linguistic, historical barriers
3. Māori and Pasifika: Cultural barriers, collective decision-making
4. CALD backgrounds: Language barriers, health system unfamiliarity
5. Low socioeconomic status: Education, access barriers
6. Acute illness: Delirium, sedation, stress impairing cognition
7. Family members under stress: Acute anxiety, grief, sleep deprivation

5. Applied Basic Sciences

Cognitive Psychology of Health Communication

Information Processing Model:

1. Attention: Information must first be attended to
2. Encoding: Converting to mental representation
3. Storage: Short-term → long-term memory
4. Retrieval: Accessing stored information when needed

Factors Impairing Processing in ICU:

• Acute stress: Reduces working memory capacity by 30-50%
• Anxiety/Depression: Impairs attention and encoding
• Sleep deprivation: Reduces cognitive function (common in ICU families)
• Information overload: More than 3-5 points overwhelms processing
• Medical jargon: Requires additional cognitive load to decode
• Emotional content: Hijacks attention, may block further processing

Cognitive Load Theory:

• Intrinsic load: Complexity of the information itself
• Extraneous load: How information is presented (jargon adds load)
• Germane load: Effort to integrate into existing knowledge
• Goal: Minimize extraneous load to maximize learning

Dual Process Theory (Kahneman):

• System 1: Fast, automatic, emotional
• System 2: Slow, deliberate, logical
• Health decisions require System 2, but stress activates System 1
• Plain language reduces cognitive load, allowing System 2 engagement

Health Literacy as Social Determinant

Conceptual Framework:

Social/Environmental Factors → Health Literacy → Health Behaviors → Health Outcomes
       ↓                              ↓                  ↓
- Education                    - Reading ability      - Adherence
- Income                       - Numeracy            - Self-management
- Culture                      - Navigation skills   - Healthcare use
- Language                     - Communication       - Prevention
                               - Critical thinking

Pathways to Poor Outcomes:

1. Direct pathway: Cannot understand instructions → medication errors
2. Indirect pathway: Low self-efficacy → poor self-management
3. Healthcare navigation: Cannot access appropriate services
4. Patient-provider communication: Suboptimal interaction quality

Readability Science

Flesch-Kincaid Grade Level Formula:

Grade Level = 0.39 × (total words / total sentences) + 11.8 × (total syllables / total words) - 15.59

Flesch Reading Ease Score:

Score = 206.835 - 1.015 × (words/sentences) - 84.6 × (syllables/words)

SMOG (Simple Measure of Gobbledygook):

Grade Level = 1.0430 × √(polysyllabic words × 30/sentences) + 3.1291

Recommended Standards:

• Patient education materials: Grade 6-8 (Flesch Reading Ease 60-70)
• Consent forms: Grade 8 maximum
• Discharge instructions: Grade 5-6 for essential information
• Medication labels: Grade 4-5

Communication Science

Schema Theory:

• New information integrated into existing mental frameworks
• Medical concepts lack schemas in most lay people
• Analogies and metaphors build new schemas
• Example: "The breathing tube is like a snorkel" builds schema

Elaboration Likelihood Model:

• Central route: Deep processing, lasting change (requires attention/motivation)
• Peripheral route: Surface processing, temporary change
• Health education should aim for central processing
• Teach-back promotes central route processing

Dual Coding Theory:

• Information processed through verbal AND visual channels
• Combined presentation (words + pictures) more effective
• Visual aids reduce cognitive load for complex concepts
• Particularly effective for low health literacy populations

6. Assessment Tools

Formal Assessment Tools

REALM (Rapid Estimate of Adult Literacy in Medicine):

Sample REALM Words: Fat, Flu, Pill, Dose, Eye, Stress, Menstrual, Antibiotics, Anemia, Diabetes, Osteoporosis, Potassium, Colitis, Impetigo

S-TOFHLA (Short Test of Functional Health Literacy in Adults):

Newest Vital Sign (NVS):

Health Literacy Questionnaire (HLQ):

Practical Screening in ICU

Single-Item Screening Questions:

BRIEF Health Literacy Screening Tool (4 items):

1. How often do you have someone help you read hospital materials?
2. How confident are you filling out forms by yourself?
3. How often do you have problems learning about your medical condition because of difficulty reading?
4. How often do you have difficulty understanding written health information?

Universal Precautions Approach:

Rather than screening individuals, assume ALL patients/families have potential health literacy challenges:

• Use plain language with everyone
• Teach-back with all communication
• Provide written summaries routinely
• Offer visual aids as standard
• This approach reduces stigma and ensures no one is missed

ICU-Specific Assessment

Signs of Potential Low Health Literacy:

• Incomplete or incorrectly filled forms
• Non-compliance with appointments/instructions
• Asking same questions repeatedly
• Bringing family member to "explain" medical information
• Avoiding reading tasks ("I forgot my glasses")
• Unable to describe medications or conditions
• Late presentation with preventable complications

Family Health Literacy Assessment in ICU:

• Observe form completion during admission
• Note repeated questions
• Assess comprehension during family meetings
• Use teach-back routinely to identify gaps
• Ask about comfort with medical terminology
• Assess emotional state (stress impairs processing)

---

7. Communication Strategies

Teach-Back Method

Definition: A technique where providers ask patients/families to repeat information in their own words to confirm understanding.

Evidence Base:

• Reduces glycemic control errors by 50% in diabetes (PMID: 12132975)
• Reduces 30-day readmissions by 30% (PMID: 21714595)
• Improves medication adherence (OR 1.5) (PMID: 26847578)
• Most effective single intervention for health literacy (AHRQ 2010)

Implementation Steps:

1. Introduce the technique: "I want to make sure I explained clearly, because this is important and I say it differently each time..."

2. Ask open-ended question: "Can you tell me in your own words what we discussed about your father's condition?"

3. Listen without interrupting: Allow complete response

4. Assess understanding: Identify gaps or misconceptions

5. Re-explain if needed: Use different words, simpler terms, or add examples

6. Repeat until confirmed: "Now that I've explained it again, can you tell me...?"

Key Phrases for Teach-Back:

• "I want to make sure I did a good job explaining..."
• "If you were explaining this to your family at home, what would you say?"
• "Just so I know we're on the same page..."
• "Can you show me how you would...?"
• "Walk me through what will happen when..."

Common Mistakes:

• Asking "Do you understand?" (yields yes/no, not demonstration)
• Asking "Do you have any questions?" (low literacy patients often don't)
• Interrupting or completing sentences for patient
• Appearing rushed or impatient
• Not re-explaining when gaps identified

Plain Language Principles

Definition: Communication that uses simple, clear language and avoids jargon, designed so the intended audience can find, understand, and use the information.

Core Principles:

Medical Jargon Translation:

Numeracy Considerations:

• Use consistent formats (1 in 5 vs 20% vs 0.2)
• Absolute numbers more understandable than percentages
• "1 in 5 people" better than "20%"
• Use visual representations (icon arrays)
• Avoid negative framing ("80% survive" vs "20% die")

Chunk and Check

Definition: Breaking information into small "chunks" of 2-3 points, checking understanding before proceeding.

Rationale: Working memory limited to ~7 items; stress reduces to 3-4 items

Implementation:

CHUNK 1: Current situation
"Your father is very sick. He has an infection in his lungs."
CHECK: "What do you understand about his current situation?"

CHUNK 2: What we're doing
"We're using antibiotics to fight the infection. We're also using a machine to help him breathe."
CHECK: "Can you tell me what treatments we're giving?"

CHUNK 3: What to expect
"We expect to know more in the next 48 hours. We'll update you every day."
CHECK: "What should you expect to hear from us?"

Visual Aids and Multimedia

Types of Visual Aids:

Evidence for Visual Aids:

• Improve recall by 60% compared to verbal alone (PMID: 9596589)
• Reduce anxiety in families viewing ICU equipment (PMID: 30057275)
• Particularly effective for low literacy populations (PMID: 21714595)
• Pictographs improve risk understanding (PMID: 11867980)

Design Principles:

• Simple, uncluttered layouts
• High contrast colors
• Consistent iconography
• Minimal text on images
• Culturally appropriate images
• Available in multiple languages

Ask-Tell-Ask Framework

Structure:

1. ASK: Explore what patient/family already knows

   • "What have the doctors told you about your mother's condition?"
   • "What is your understanding of what is happening?"

2. TELL: Provide information based on their level

   • Correct misconceptions first
   • Build on existing knowledge
   • Use plain language and chunk information

3. ASK: Check understanding

   • "What questions do you have?"
   • Teach-back: "Can you tell me in your own words...?"

Benefits:

• Identifies baseline knowledge and misconceptions
• Allows tailoring of information level
• Demonstrates respect for family's understanding
• Creates dialogue rather than lecture

13. SAQ Practice Questions

SAQ 1: Informed Consent and Health Literacy

Question:

A 68-year-old Aboriginal man from a remote community in the Northern Territory has been in ICU for 10 days with severe community-acquired pneumonia requiring mechanical ventilation. He is now weaning successfully but will require a tracheostomy to facilitate further weaning. His wife is his substitute decision-maker. She has completed Year 8 education, speaks English as a second language, and appears overwhelmed by the ICU environment. The surgical team has asked you to obtain consent for the tracheostomy.

a) Outline factors that may contribute to health literacy challenges in this scenario. (6 marks)

b) Describe your approach to ensuring valid informed consent, including specific strategies to address health literacy barriers. (8 marks)

c) How would you document this consent discussion? (6 marks)

Model Answer:

a) Factors Contributing to Health Literacy Challenges (6 marks)

Patient and Family Factors (3 marks):

• English as second language - requires interpreter
• Year 8 education - limited formal education
• Remote community - unfamiliarity with tertiary hospital systems

14. Viva Scenarios

Viva 1: Health Literacy Concepts and Assessment

Scenario: You are asked to discuss health literacy as a concept and its relevance to ICU practice.

---

Examiner: Can you define health literacy and explain why it's important in the ICU setting?

Candidate: Health literacy is defined as the cognitive and social skills that determine an individual's motivation and ability to gain access to, understand, and use information in ways that promote and maintain good health. The WHO and Institute of Medicine definitions emphasize the capacity to obtain, process, and understand basic health information needed for appropriate health decisions.

In ICU, health literacy is critically important for several reasons:

First, informed consent - 70-95% of ICU patients lack decision-making capacity, so we rely on substitute decision-makers who need to understand complex medical information to make valid decisions.

Second, family communication - 82% of ICU families don't understand key medical terminology, according to Azoulay's research. Miscommunication leads to unrealistic expectations and potential conflict.

Third, outcomes - systematic reviews show low health literacy is associated with a 50% higher mortality rate, with hazard ratios around 1.5. It also predicts higher readmission rates and poorer self-management.

Fourth, transitions of care - ICU discharge instructions require families and patients to manage complex medications, recognize warning signs, and navigate the health system.

---

Examiner: What is Nutbeam's model of health literacy levels?

Candidate: Nutbeam's model, published in 2000, describes three levels of health literacy that build upon each other:

Functional health literacy is the basic level - the ability to read and write sufficiently to understand simple health information, like medication labels or appointment times. Most traditional patient education targets only this level.

Interactive or communicative health literacy is the second level - more advanced cognitive and social skills that allow someone to extract meaning from communication, apply new information to changing circumstances, and interact effectively with healthcare providers. This includes asking questions and participating in consultations.

Critical health literacy is the highest level - the ability to critically analyze health information, understand social determinants of health, and take action at personal and community levels to address health issues. This empowers patients to navigate the health system and advocate for themselves.

In ICU, we often focus on functional literacy when providing information, but we really need families to achieve interactive literacy to participate in shared decision-making effectively.

---

Examiner: What is the prevalence of low health literacy in Australia, and which populations are most affected?

Candidate: According to the Australian Bureau of Statistics Adult Literacy and Life Skills Survey from 2006, which remains our most comprehensive data, 59% of Australian adults have inadequate or marginal health literacy. This means the majority of Australians struggle to understand and use health information effectively.

Prevalence increases significantly with age - 66% of those aged 65-74 and 82% of those 75 and older have inadequate health literacy. This is particularly relevant in ICU where our patient population skews older.

Socioeconomic gradients are also marked - 75% of those in the lowest socioeconomic quintile compared to 41% in the highest quintile have inadequate health literacy.

Geographic disparities exist - 66% rural/remote versus 57% urban.

Aboriginal and Torres Strait Islander Australians are estimated at 70-75% inadequate health literacy, though this is an estimate applying the same methodology as the national survey.

In New Zealand, similar patterns are seen, with 56% of the general population, 65% of Māori, and 75% of Pasifika peoples having inadequate health literacy.

This means in any ICU, we should assume the majority of our patients and families have some degree of health literacy limitation.

---

Examiner: How would you assess health literacy in the ICU setting?

Candidate: There are formal assessment tools and practical approaches.

Formal tools include the REALM - Rapid Estimate of Adult Literacy in Medicine - which is a 66-word recognition test taking 2-3 minutes. Patients pronounce medical words and the score correlates with reading grade level. It's quick but only tests word recognition, not comprehension.

The S-TOFHLA - Short Test of Functional Health Literacy in Adults - includes 36 reading comprehension items and 4 numeracy items, taking 7-12 minutes. It tests actual comprehension but is longer to administer and may embarrass patients.

The Newest Vital Sign uses a nutrition label and 6 questions, taking about 3 minutes. It tests reading and numeracy in a less stigmatizing way.

For practical screening in ICU, single-item questions are useful. The question "How confident are you filling out medical forms by yourself?" has reasonable sensitivity and specificity for identifying limited health literacy.

However, the recommended approach is Universal Precautions - assuming everyone may have health literacy challenges and using plain language, teach-back, and visual aids with all patients and families. This avoids stigmatization and ensures no one is missed.

Practical signs of potential low health literacy in ICU include: incomplete forms, repeatedly asking the same questions, bringing family members to "help explain," avoiding reading tasks, unable to describe their medications, and late presentation with preventable complications.

---

Examiner: What is the evidence that health literacy interventions improve outcomes?

Candidate: The strongest evidence comes from systematic reviews and landmark studies.

Berkman's 2011 systematic review in the Annals of Internal Medicine, PMID 21714595, found consistent evidence that low health literacy is associated with more hospitalizations, greater emergency department use, lower use of preventive services, poorer medication adherence, and higher mortality - independent of education and socioeconomic status.

For interventions, Schillinger's 2003 study on teach-back in diabetes, PMID 12132975, showed that physicians who used teach-back had patients with significantly better glycemic control. Those whose physicians assessed understanding had HbA1c 0.5% lower.

A systematic review of teach-back by Ha Dinh in 2016 confirmed its effectiveness in improving knowledge, adherence, and self-care across multiple chronic conditions.

In ICU specifically, Jones' RACHEL trial in 2010, PMID 20494556, showed ICU diaries reduce PTSD symptoms - 5% versus 13%, with a number needed to treat of 12.

Azoulay's research showed that family information leaflets combined with verbal explanation improve comprehension by approximately 30%.

The evidence supports multicomponent interventions - combining plain language, teach-back, written materials, and visual aids - rather than any single strategy alone.

---

Examiner: Thank you. That's a comprehensive understanding of health literacy.

Viva 2: Communication Strategies and Indigenous Health

Scenario: A 55-year-old Torres Strait Islander woman is in ICU with severe sepsis. Her extended family has traveled from Thursday Island. You need to discuss the possibility of withdrawing life support.

---

Examiner: How would health literacy considerations affect your approach to this family meeting?

Candidate: This scenario has multiple layers of health literacy challenges that would significantly shape my approach.

First, the cultural context - Torres Strait Islander communities have distinct cultural protocols that differ from both mainland Aboriginal cultures and Western approaches. Decision-making is typically collective, involving extended family and Elders. There may be specific gender considerations in who discusses what topics.

Second, language considerations - while English may be spoken, it may not be the first language. English proficiency doesn't guarantee health literacy, and medical concepts may not translate directly.

Third, the geographic and socioeconomic context - Thursday Island is remote, the family may be unfamiliar with tertiary hospital settings and systems, and there may be limited prior experience with intensive care.

Fourth, historical trauma - Indigenous Australians have experienced significant historical trauma in healthcare settings, potentially affecting trust and engagement.

Fifth, stress compounding baseline literacy - the acute stress of a critically ill family member further impairs information processing.

My approach would involve significant preparation and adaptation of standard communication practices.

---

Examiner: What specific steps would you take before the family meeting?

Candidate: Preparation is critical in this scenario.

First, I would involve the Aboriginal Hospital Liaison Officer or Torres Strait Islander Health Worker immediately - this is essential, not optional. I would brief them on the clinical situation and seek their guidance on cultural protocols for this family specifically.

Second, I would identify key family members and decision-making structure. This might mean asking the AHLO to help identify who the Elders are, whether there are specific spokespersons, and who needs to be present for a significant decision.

Third, I would arrange appropriate interpreter services if needed - not family members - even if the family speaks English, professional interpretation may improve understanding.

Fourth, I would allow adequate time - Torres Strait Islander families may need extended time for discussion among themselves. I would block out at least 90 minutes rather than a standard 30-minute meeting.

Fifth, I would prepare visual aids and consider drawing diagrams to explain organ failure and what life support means.

Sixth, I would choose an appropriate space - somewhere private with enough room for an extended family group, potentially outside the clinical environment.

Seventh, I would coordinate with the team to ensure consistency of message and identify who should be present from the medical team.

---

Examiner: Describe how you would conduct the meeting itself.

Candidate: The meeting conduct would involve several key modifications.

Opening: I would begin by acknowledging that we're meeting on Aboriginal land, introducing myself and my role, and thanking the family for traveling from Thursday Island. I would allow the AHLO to make cultural introductions if appropriate.

Exploring understanding: Using Ask-Tell-Ask, I would start by exploring what the family already understands about their mother's condition. "What have the doctors told you so far about what's happening?" This helps me gauge baseline understanding and identify misconceptions.

Communication style: I would use plain language, avoiding medical jargon entirely. "Her body is very sick. The infection has spread through her blood and her organs - her kidneys, her liver, her lungs - are not working properly anymore." I would speak slowly, use short sentences, and pause frequently.

Chunk and check: I would provide information in small chunks - 2-3 points maximum - then check understanding before proceeding. "I've explained that the infection has affected many organs. Can you tell me what you understand about that?"

Allowing silence: Torres Strait Islander communication styles may include more silence than Western approaches. I would be comfortable with pauses and not rush to fill silence.

Prognostication: I would be honest about the grave prognosis while acknowledging uncertainty. "I'm worried that despite everything we're doing, she may not survive this illness. I wish I could give you better news."

Exploring values: Rather than immediately discussing withdrawal, I would explore what's important to the family. "What would your mother want us to know about what matters to her?"

Decision-making: I would acknowledge that this is a decision for the family to make together, not on the spot. "This is a big decision. You need time to talk among yourselves. We can meet again when you're ready."

---

Examiner: The family seems to be struggling to understand the prognosis. What would you do?

Candidate: If the family is struggling to understand, several strategies could help.

First, I would use teach-back to identify specifically what's unclear. "I want to make sure I'm explaining clearly. Can you tell me in your own words what you understand about how sick she is?"

Second, I would involve the AHLO more actively - they may be able to explain concepts in a culturally appropriate way or identify cultural barriers I'm not seeing.

Third, I would use more visual aids - drawing a simple body outline and indicating affected organs, using gestures, or using props if available.

Fourth, I would try different explanations and analogies. Instead of "multi-organ failure," I might say "All the main parts of her body that keep her alive - her breathing, her blood cleaning kidneys, her thinking brain - they've all stopped working properly because of this infection."

Fifth, I would acknowledge that this is hard to take in. "This is very difficult news. It's normal to have trouble taking it all in. Would it help if we took a break and talked again later?"

Sixth, I would offer to repeat information. "Sometimes when we hear hard news, it's difficult to remember everything. Would you like me to go over the important parts again?"

Seventh, I would provide a written summary in plain language for the family to take away and discuss.

Finally, I would recognize that understanding may come over time with repeated conversations. This may not be a single meeting but a series of discussions as the family processes the information.

---

Examiner: If the family asks you to "do everything," how would you respond?

Candidate: A request to "do everything" in this context requires careful exploration rather than immediate acceptance or refusal.

First, I would acknowledge the request with empathy. "I can hear how much you love your mother and want her to survive. It's natural to want us to do everything possible."

Second, I would explore what "everything" means to them. "When you say 'do everything,' can you tell me what that means to you? What are you hoping for?"

Third, I would explore values and goals. "If your mother could speak to us right now, what do you think she would say about what's important to her?"

Fourth, I would provide honest prognostic information using plain language. "I have to be honest with you. Even though we're doing everything our machines and medicines can do, her body is not getting better. I'm worried that she's dying despite our treatments."

Fifth, I would reframe "everything" if appropriate. "We want to do everything that will help her. Right now, that might mean making sure she's comfortable and not suffering, rather than treatments that cause more pain without helping her get better."

Sixth, I would acknowledge uncertainty. "Medicine isn't perfect. We can't always predict exactly what will happen. But based on what we're seeing, I'm worried she won't survive."

Seventh, I would not push for a decision. "I'm not asking you to make any decisions right now. I wanted to share my concerns honestly. Take time to talk as a family, and we'll meet again."

Finally, I would document the conversation carefully, including the family's request, the information provided, and the plan for ongoing discussions.

---

Examiner: Thank you. That demonstrates excellent understanding of health literacy in a culturally complex situation.
