ICU Administration and Management: Structure, Staffing, Governance, and Quality

Quick Answer

ICU Administration and Management encompasses the organizational structures, staffing models, governance frameworks, accreditation requirements, and quality systems that ensure safe, effective, and efficient delivery of critical care. In Australia and New Zealand, the College of Intensive Care Medicine (CICM) standards (IC-1 through IC-21) define minimum requirements, while ANZICS-CORE provides benchmarking data.

Key Administrative Principles:

• ICU Levels: Level 1 (basic stabilization), Level 2 (general ICU), Level 3 (tertiary referral)
• Staffing Models: High-intensity (closed) vs low-intensity (open); closed model reduces mortality by 15-40%
• Intensivist Ratio: Optimal 1:8 to 1:12; mortality increases significantly >1:15
• Nursing Ratio: 1:1 for ventilated/critically ill; 1:2 for HDU level
• Accreditation: CICM training accreditation + NSQHS Standards via ACHS
• Quality Metrics: SMR, SLOS, ICU readmission, after-hours discharge rates

CICM Guidelines: IC-1 defines minimum standards for ICU levels; IC-13 covers HDU; IC-14 addresses Level I/II specific requirements. Participation in ANZICS-CORE data collection is mandatory for accreditation.

Critical Safety Issues: After-hours discharge (18:00-06:00) increases mortality by 31%; intensivist workload exceeding 1:15 ratio triples mortality risk; suboptimal nurse staffing increases adverse events.

Key Points

Must-Know Facts

1. ICU Levels (IC-1): Level 1 = stabilization and short-term ventilation before transfer; Level 2 = indefinite multi-system support without highly specialized services; Level 3 = tertiary referral with comprehensive capabilities including ECMO, complex neurotrauma (CICM IC-1 2016)

2. High-Intensity Staffing: Closed ICU model with mandatory intensivist involvement reduces ICU mortality by 39% and hospital mortality by 29% (PMID: 12417539)

3. Intensivist-to-Patient Ratio: Optimal ratio 1:8 to 1:12; mortality increases significantly when ratio exceeds 1:14-15; workload >1:15 associated with 3.5-fold mortality increase (PMID: 28249116, 27153308)

4. Nursing Ratios: 1:1 for ventilated/critically ill patients; 1:2 for HDU level; lower ratios associated with increased mortality, VAP, and pressure injuries (PMID: 12028354, 21388309)

5. ICU Director Role: Clinical leadership, governance authority, protocol development, quality oversight, budget management, staff development; requires FCICM qualification (PMID: 10405108)

6. After-Hours Discharge: Discharge between 18:00-06:00 increases hospital mortality by 31% and ICU readmission risk; should be avoided unless clinically necessary (PMID: 26035272, 18451124)

7. ANZICS-CORE Benchmarking: SMR (Standardized Mortality Ratio), SLOS (Standardized Length of Stay), readmission rates, after-hours discharge rates; participation mandatory for CICM accreditation

8. NSQHS Standards: 8 National Safety and Quality Health Service Standards; Standard 8 (Acute Deterioration) particularly relevant to ICU; ACHS provides accreditation

9. Dyad/Triad Governance: Medical Director + Nurse Unit Manager (dyad) or +Administrative Director (triad); shared governance improves quality implementation (PMID: 26164214)

10. Indigenous Health Disparities: Aboriginal/Torres Strait Islander and Maori patients admitted younger, higher severity, more sepsis; adjusted ICU mortality often equivalent but higher disease burden and access barriers (PMID: 37203411)

ICU Organizational Structure

ICU Level Classification (CICM IC-1)

The College of Intensive Care Medicine (CICM) defines three levels of ICU based on capability:

Level 1 ICU (Basic/Local)

Definition: Capable of providing immediate resuscitation, short-term cardiorespiratory support, and stabilization prior to transfer.

Capabilities:

• Basic invasive monitoring (arterial line, CVP)
• Short-term mechanical ventilation (24-48 hours)
• Vasoactive infusions for stabilization
• Limited imaging and laboratory support

Staffing Requirements:

• Medical: Physician with ICU experience available 24/7; specialist consultation via telemedicine
• Nursing: 1:1 or 1:2 ratio depending on acuity

Location: Typically rural/regional hospitals, smaller metropolitan hospitals

Transfer Requirement: Patients requiring prolonged mechanical ventilation, RRT, or specialized interventions must be transferred to Level 2 or 3

Level 2 ICU (General)

Definition: Capable of providing comprehensive multi-system life support for an indefinite period.

Capabilities:

• Advanced invasive monitoring
• Prolonged mechanical ventilation
• Renal replacement therapy (CRRT)
• Basic neurocritical care
• Post-cardiac surgery care (in some units)

Staffing Requirements:

• Medical Director: FCICM
• 24/7 specialist availability (may be rostered on-call)
• At least 1 registrar with 12+ months ICU experience rostered at all times
• Nursing: 1:1 for ventilated patients; 1:2 for lower acuity

Limitations: May lack highly specialized services (ECMO, complex neurosurgery, cardiac transplant)

Level 3 ICU (Tertiary Referral)

Definition: Comprehensive critical care unit providing the highest level of care, serving as a regional referral center.

Capabilities:

• All Level 2 capabilities plus:
• ECMO (VV and VA)
• Complex neurotrauma and neurocritical care
• Cardiac surgery and transplantation
• Burns care
• Obstetric critical care
• Paediatric ICU (co-located or separate)
• Research and teaching programs

Staffing Requirements:

• Full-time Medical Director (FCICM)
• 24/7 on-site specialist coverage (dedicated to ICU)
• Multiple registrars with graded experience
• Subspecialty consultation available on-site
• Nursing: 1:1 minimum; supernumerary in charge

Role: Regional referral, teaching, research, complex case management

ICU Level Comparison Table

High Dependency Units (HDU) - IC-13

Definition: Units providing care intermediate between general ward and ICU for patients requiring:

• Close monitoring without invasive support
• Single-organ support (non-invasive ventilation, specific infusions)
• Step-down from ICU

Staffing:

• Nursing: Minimum 1:2 ratio
• Medical: Under supervision of FCICM; may have shared staffing with ICU
• Allied health access

Co-Location: CICM recommends HDU be adjacent to or integrated within Level 2/3 ICU for rapid escalation

Staffing Models

Medical Staffing Models

High-Intensity (Closed) Model

Definition: Intensivist is the primary attending physician OR mandatory consultant for ALL ICU patients.

Structure:

• All admissions managed or co-managed by ICU team
• Intensivist leads daily rounds
• Primary team (surgery, medicine) provides consultative input
• ICU team controls admission/discharge decisions

Evidence:

• Pronovost Systematic Review (2002): High-intensity staffing reduces ICU mortality by 39% (RR 0.61) and hospital mortality by 29% (RR 0.71) (PMID: 12417539)
• Young et al (2000): Transition to closed ICU improved outcomes and reduced costs (PMID: 11074744)
• Kahn et al (2020): Strong ICU leadership is a top-tier predictor of low mortality (PMID: 32097166)

Advantages:

• Consistent care protocols
• Better communication and coordination
• Higher compliance with bundles (VAP, CLABSI prevention)
• Reduced length of stay
• Lower mortality

Challenges:

• Requires adequate intensivist numbers
• May create tension with referring teams
• Potential for de-skilling of primary teams

Low-Intensity (Open) Model

Definition: Primary admitting physician (surgeon, internist) manages the patient; intensivist consulted at discretion.

Structure:

• Admitting team retains primary responsibility
• ICU provides consultative support
• Variable involvement of ICU specialists

Evidence: Associated with higher mortality, longer LOS, more complications (PMID: 12417539)

Persistence: Still exists in some surgical units where specialty wishes to retain control

Hybrid Model

Definition: Intensivist is mandatory co-manager but shares responsibility with primary team.

Structure:

• All patients have both primary team and ICU team involvement
• Shared decision-making
• ICU manages organ support; primary team manages underlying condition

Applications: Common in specialized surgical units (cardiac surgery, transplant)

Intensivist-to-Patient Ratio

Evidence for Optimal Ratios

Tipping Point:

• Neuraz et al (2017): Workload exceeding threshold associated with 3.5-fold increase in mortality (PMID: 28249116)
• Ali et al (2016): Ratios >1:14 associated with worse outcomes (PMID: 27153308)
• Optimal range: 1:8 to 1:12 (PMID: 27153308)

Workload Components:

• Direct patient care
• Family communication
• Administrative duties
• Teaching and supervision
• Quality improvement activities

Recommendations:

• Daytime ratio: ≤1:12
• If ratio frequently exceeds 1:15: Add second intensivist or APP (NP/PA)
• Night coverage: May use telemedicine support if on-site intensivist unavailable

24/7 In-Hospital Intensivist Coverage

Evidence:

• Wallace et al (2012): 24/7 coverage improves outcomes in open/hybrid ICUs but minimal additional benefit in already-closed daytime model (PMID: 22670902)
• Gajic et al (2013): Reduces "nighttime effect" in certain settings (PMID: 23697920)

Current Recommendations:

• Level 3 ICUs: 24/7 on-site intensivist preferred
• Level 2 ICUs: 24/7 availability (on-site or rapid response from home)
• Telemedicine (tele-ICU): May supplement but not replace on-site coverage

Nursing Staffing Models

Evidence for Nurse-to-Patient Ratios

Landmark Studies:

• Aiken et al (2002): Each additional patient per nurse associated with 7% increase in mortality and 7% increase in failure-to-rescue (PMID: 12028354)
• Needleman et al (2011): RN staffing below target associated with increased mortality during that shift (PMID: 21388309)
• Griffiths et al (2019): Higher nurse ratios reduce complications (VAP, pressure ulcers, falls), making staffing cost-effective despite salary costs (PMID: 30855365)

CICM/ACCCN Recommendations

Skill Mix:

• Minimum proportion of specialist ICU-trained nurses
• Graduate nurse programs with supervision
• Clinical Nurse Consultant/Educator roles

Allied Health Staffing

Recommended Disciplines:

• Physiotherapy: Essential for early mobilization, respiratory physiotherapy
• Pharmacy: Clinical pharmacist reduces medication errors by 66% (PMID: 11030362)
• Dietetics: Nutrition optimization
• Social work: Family support, discharge planning
• Speech pathology: Swallowing assessment, communication
• Occupational therapy: Cognitive rehabilitation, ADLs
• Pastoral care: Spiritual support

Evidence for Multidisciplinary Teams:

• Pronovost (2003): Daily multidisciplinary rounds with structured communication reduce LOS (PMID: 14755198)
• Kim (2010): Dedicated ICU pharmacist reduces medication errors by 66% (PMID: 11030362)

Resource Allocation and Budgeting

ICU Cost Structure

Cost Distribution:

• Labor (staffing): 50-60% of daily costs
• Consumables/pharmaceuticals: 20-30%
• Equipment/capital: 10-15%
• Overhead: 5-10%

ICU Cost Context:

• ICU accounts for 13-20% of total hospital costs
• Approximately 0.5-1% of healthcare GDP in developed countries
• Daily ICU cost: AUD $3,000-5,000 (Australia); higher for complex patients

Cost Drivers:

• Length of stay (primary variable cost)
• Mechanical ventilation duration
• Renal replacement therapy
• ECMO/advanced therapies
• Staffing levels

Budgeting Principles

Activity-Based Funding

Diagnosis Related Groups (DRGs):

• ICU care funded through DRG weighting
• ICU component adds "complexity weighting" to episode
• Outlier payments for prolonged stays

Challenges:

• DRGs may not capture true ICU resource consumption
• Incentive to discharge early (risk of readmission)
• May undervalue complex, long-stay patients

Zero-Based Budgeting

• Start from zero each budget cycle
• Justify all expenditure
• Identify cost-saving opportunities
• Used for major reviews

Cost-Effectiveness in ICU

Evidence-Based Resource Use

Pronovost (2002): High-intensity staffing is cost-effective despite higher salary costs due to reduced LOS and complications (PMID: 21747040)

Griffiths (2019): Higher nurse ratios cost-effective due to reduced complications (PMID: 30855365)

Kahn (2012): Protocolized care (weaning, sedation holidays) is primary driver of cost-effectiveness (PMID: 22441631)

Low-Value Care Reduction

Bice (2019): "Choosing Wisely" initiatives can reduce ICU budgets without compromising safety (PMID: 30730419)

Examples of Low-Value Practices:

• Routine daily chest X-rays
• Excessive blood testing
• Over-transfusion (Hb >70 in stable patients)
• Prolonged antimicrobial courses
• Maintenance IV fluids in stable patients

ICU Triage and Resource Allocation

SCCM Triage Guidelines (PMID: 27124445)

Priority Categories:

• Priority 1: Unstable, needs immediate ICU monitoring/treatment, expected to benefit
• Priority 2: Intensive monitoring required, immediate intervention possible
• Priority 3: Unstable, low probability of recovery (discuss with family)
• Priority 4a: Too well - does not need ICU level care
• Priority 4b: Too sick - futile, comfort care appropriate

Triage Principles:

• Medical criteria primary
• Avoid "first-come-first-served" in scarcity
• Explicit, transparent criteria
• Regular review and discharge when appropriate

Ethical Framework for Allocation

Principles (PMID: 32219616):

• Maximize benefit (save most lives/life-years)
• Treat people equally
• Promote and reward instrumental value
• Give priority to the worst off

Australian Context:

• No explicit "rationing" language
• Resource allocation decisions should be collegial
• Ethics consultation for complex cases
• Avoid individual clinician "gatekeeping"

• Requires funnel plot interpretation for statistical validity (PMID: 15568106)

ICU Mortality: Deaths occurring in ICU

Hospital Mortality: Deaths occurring after ICU discharge but before hospital discharge; captures "premature" discharges

Post-Hospital Mortality: Increasingly recognized as important; 90-day and 1-year outcomes

Length of Stay

Standardized Length of Stay (SLOS):

• Actual LOS / Expected LOS
• Expected derived from case-mix adjustment

• SLOS >1.0 = less efficient

ICU LOS: Days in ICU

Hospital LOS: Total hospital stay

ICU Readmission

Definition: Return to ICU within defined period (usually 48-72 hours) of discharge

Significance:

• Readmission associated with 4-fold increased mortality risk
• High rates may indicate premature discharge or poor ward care
• Quality indicator for discharge decision-making

Targets: Generally aim for <5% readmission rate within 48 hours

Indigenous Health Considerations

Disparities in ICU Access and Outcomes

Aboriginal and Torres Strait Islander Peoples (Australia)

Epidemiology (PMID: 37203411, 35140889):

• 2-3× higher age-standardized ICU admission rates
• Mean age of admission 10-20 years younger (40s-50s vs 60s-70s)
• Higher burden of chronic disease (diabetes, renal, cardiovascular)
• Higher rates of sepsis and respiratory infections
• Higher severity scores (APACHE) at admission reflecting delayed presentation

Outcomes:

• Adjusted ICU mortality often equivalent to non-Indigenous patients when inside ICU
• Higher raw mortality rates due to higher severity at admission
• Potential higher post-ICU mortality due to access barriers for follow-up care
• Higher rates of discharge against medical advice (DAMA)

Barriers to Optimal Care:

• Geographic access: Remote/rural populations require transfer to tertiary centers
• Cultural safety concerns leading to delayed presentation
• Health literacy and communication barriers
• Lack of Indigenous health workforce in ICU
• Family and cultural obligations affecting hospital stay

Maori (New Zealand)

Epidemiology (PMID: 31112415):

• Higher ICU admission rates
• Younger age at admission
• Higher comorbidity burden
• Higher rates of sepsis

Outcomes:

• Higher raw mortality
• Adjusted mortality often comparable after case-mix adjustment

Cultural Safety in ICU

Key Principles:

• Self-determination: Involve patient and family in all decisions
• Recognize collective decision-making: Extended family involvement expected
• Elder (kaumātua) involvement: Decisions may require elder consultation
• Interpreter services: Language access is a right
• Cultural liaison: Aboriginal Health Worker/Liaison Officer (AHW/AHLO) involvement

Practical Recommendations:

• Early involvement of Aboriginal Health Worker/Liaison Officer
• Flexible visiting policies for extended family
• Accommodate cultural and spiritual practices
• Consider connection to Country/land for remote patients
• Allow time for family consultation before major decisions
• Be aware of "Sorry Business" and cultural obligations

Communication Considerations

Aboriginal and Torres Strait Islander Peoples:

• Indirect communication style preferred by some communities
• Silence may indicate respect, not disengagement
• Eye contact norms vary by community
• Storytelling approach may be preferred over direct Q&A
• Time for family discussion before decisions

Maori:

• Whanau (family)-centered approach
• Kaumatua (elder) involvement for major decisions
• Te Whare Tapa Wha model: Physical, mental, spiritual, family health
• Karakia (prayer/blessing) may be requested
• Tangihanga (mourning practices) considerations at end of life

Administrative Implications

Data Collection:

• Indigenous status collection in ANZICS-CORE
• ANZROD model includes Indigenous status as predictor
• Important for health service planning

Staffing:

• Recruit and retain Indigenous health workforce
• Cultural awareness training for all staff
• Aboriginal Health Worker access

Access:

• Telemedicine to support rural/remote ICUs
• Retrieval service equity
• Post-ICU follow-up services

Quality Improvement:

• Track Indigenous patient outcomes separately
• Equity-focused quality indicators
• Community engagement in QI initiatives

SAQ 2: After-Hours Discharge and Quality Improvement (20 marks)

Stem: You are the ICU Director reviewing your unit's quarterly ANZICS-CORE report. The after-hours discharge rate (18:00-06:00) has increased from 12% to 28% over the past year, and the ICU readmission rate has risen from 4% to 8%.

Question: a) Explain the significance of elevated after-hours discharge rates (5 marks) b) Outline the likely causes of this increase (5 marks) c) Describe the quality improvement methodology you would apply to address this (5 marks) d) What specific interventions might you implement? (5 marks)

---

Model Answer:

(a) Significance of Elevated After-Hours Discharge Rates (5 marks)

Mortality Impact:

• After-hours discharge (18:00-06:00) associated with 31% increased hospital mortality (OR 1.39) (PMID: 26035272 - Gershengorn meta-analysis)
• Original Goldfrad & Rowan study: 1.6× higher mortality (PMID: 18451124)

Readmission Impact:

• Strong correlation between after-hours discharge and ICU readmission
• Readmission within 48 hours associated with 4-fold increased mortality

Mechanisms of Harm:

• Reduced ward nursing staff at night (higher patient:nurse ratios)
• Reduced monitoring capability
• Poorer handover quality at night
• Delayed recognition of deterioration
• Limited medical cover on wards overnight
• Reduced access to investigations and interventions

Quality Indicator:

• After-hours discharge rate is a recognized ANZICS-CORE quality indicator
• Reflects both patient safety risk and potential bed pressure issues

(b) Likely Causes of Increase (5 marks)

Demand Pressures:

• Increased ICU demand without bed capacity increase
• Pressure to accept new admissions (from ED, operating theatre, wards)
• High occupancy rates forcing "bed clearing" at night

System Factors:

• Inadequate discharge planning during day shift
• Delays in ward bed availability during daytime
• Reduced focus on discharge timing as quality metric

Staffing Factors:

• Night registrar more likely to discharge to meet bed pressure
• Consultant oversight reduced at night
• Nursing shift change may delay daytime discharges

Case-Mix Changes:

• Higher acuity admissions requiring longer stays
• Increased surgical caseload with post-operative admissions occurring at night
• COVID-19 or other pandemic pressures (if applicable)

Culture:

• Normalization of after-hours discharge
• Focus on admission capability rather than discharge quality

(c) Quality Improvement Methodology (5 marks)

Select Methodology: Plan-Do-Study-Act (PDSA) cycles

PLAN Phase:

• Form QI team: ICU Director, NUM, registrar representative, MET coordinator, ward NUM
• Define problem: After-hours discharge rate 28% (target <15%)
• Root cause analysis of recent after-hours discharges
• Identify modifiable factors

DO Phase:

• Implement small-scale test of change (e.g., discharge planning checklist by 1400 daily)
• Trial on one week initially
• Collect data on discharge timing

STUDY Phase:

• Analyze results: Did afternoon discharges increase? Did after-hours discharges decrease?
• Assess unintended consequences (premature discharge, readmissions)

ACT Phase:

• If successful: Scale up across unit
• If unsuccessful: Modify intervention and repeat cycle
• Sustain with ongoing monitoring

Alternative Methodologies:

• Lean: Focus on waste elimination in discharge process
• Six Sigma: Define-Measure-Analyze-Improve-Control (DMAIC)

(d) Specific Interventions (5 marks)

Discharge Planning Interventions:

1. Daily Goals Round at 0900: Identify patients potentially suitable for discharge
2. Discharge Planning Checklist by 1400: Medical clearance, physiotherapy, dietetics, medications, ward bed
3. Protected Discharge Time: Target discharges between 1000-1600
4. Board Round: Visual management of discharge status

Capacity Interventions:

1. Ward Bed Coordinator: Facilitate timely ward bed availability
2. HDU Utilization: Step-down patients earlier in day
3. Avoid Elective Surgery Late in Day: Reduces evening admissions

After-Hours Protocols:

1. Consultant Approval for After-Hours Discharge: Requirement for senior review
2. Enhanced Handover Protocol: Structured ISBAR with documented MET review plan

Viva Scenarios

Viva 1: ICU Structure and Staffing Evidence

Opening Stem: "You are being considered for the position of ICU Director at a 16-bed metropolitan ICU. The hospital CEO asks you to explain what staffing model you would implement."

---

Examiner: What staffing model would you recommend for this ICU?

Candidate: I would recommend a high-intensity or "closed" ICU model, where the intensivist is the primary attending physician or mandatory consultant for all patients.

Examiner: What is your evidence for that recommendation?

Candidate: The strongest evidence comes from the Pronovost systematic review published in JAMA in 2002 (PMID: 12417539). This meta-analysis of 26 studies found that high-intensity staffing was associated with a 39% reduction in ICU mortality (relative risk 0.61) and a 29% reduction in hospital mortality (relative risk 0.71) compared to low-intensity models.

Examiner: What about 24/7 in-hospital intensivist coverage?

Candidate: The evidence for 24/7 in-hospital coverage is more nuanced. The Wallace study in 2012 (PMID: 22670902) found that 24/7 coverage improved outcomes in ICUs that did not already have a high-intensity daytime model. However, for units that are already "closed" during the day, the addition of 24/7 in-hospital coverage showed minimal additional mortality benefit.

For a 16-bed metropolitan Level 2 or 3 ICU, I would recommend:

• Dedicated on-site intensivist during daytime hours
• On-call coverage overnight with rapid response capability
• Consider tele-ICU support to supplement night coverage
• If activity and case-mix warrant it, move toward 24/7 on-site

Examiner: What intensivist-to-patient ratio would you aim for?

Candidate: Evidence suggests an optimal ratio of 1:8 to 1:12. The Neuraz study in 2017 (PMID: 28249116) found that when workload exceeded thresholds, there was a 3.5-fold increase in mortality. The Ali study (PMID: 27153308) identified that ratios exceeding 1:14 were associated with worse outcomes.

For a 16-bed unit at 80-85% occupancy, I would staff for 12-14 patients during peak hours, meaning at least one intensivist on the unit during the day, and potentially overlap coverage during busy periods.

Examiner: What about nursing ratios?

Candidate: Based on CICM IC-1 standards and ACCCN guidelines:

• 1:1 ratio for all ventilated and critically ill patients
• 1:2 ratio for stable or HDU-level patients
• A supernumerary in-charge for the unit

The evidence base includes the Aiken study (2002, PMID: 12028354) showing that each additional patient per nurse increased mortality by 7% and failure-to-rescue by 7%. The Needleman study (2011, PMID: 21388309) showed that staffing below target on a given shift was associated with increased mortality during that shift.

Examiner: How would you address governance for this unit?

Candidate: I would establish a dyad leadership model with myself as Medical Director and the Nurse Unit Manager as my counterpart. Evidence from Steinberg (2015, PMID: 26164214) supports that interdisciplinary collaboration improves quality implementation.

We would have shared accountability for:

• Clinical outcomes (SMR, readmission rates)
• Safety metrics (CLABSI, VAP)
• Operational efficiency (LOS, bed utilization)

Essential committees would include:

• Monthly M&M meetings
• Quality and Safety Committee
• Clinical Practice Committee
• Education Committee

All of this would be underpinned by mandatory participation in ANZICS-CORE for benchmarking.

Examiner: The CEO asks why ANZICS-CORE participation is important. What do you say?

Candidate: ANZICS-CORE participation is:

1. Mandatory for CICM training accreditation - we cannot train registrars without it
2. Provides validated benchmarking - our SMR is calculated using ANZROD, which is recalibrated for Australian/NZ case-mix and updated annually
3. Enables quality comparison - we can compare our outcomes to peer units (metropolitan Level 2/3) using funnel plots that account for case volume
4. Identifies areas for improvement - after-hours discharge rates, readmission rates, and other quality indicators help us target QI efforts
5. Supports health service planning - capacity data contributes to state and national planning

Examiner: Good. How would you address Indigenous health considerations in your ICU administration?

Candidate: This is critical for equitable care delivery. Key considerations include:

Staffing and Support:

• Ensure access to Aboriginal Health Worker/Liaison Officer (AHW/AHLO) for all Indigenous patients
• Cultural awareness training for all staff
• Consider recruitment of Indigenous staff members

Care Delivery:

• Flexible visiting policies for extended family
• Accommodate collective decision-making with elders
• Allow time and space for cultural and spiritual practices

Quality Monitoring:

• Track Indigenous patient outcomes separately in our data
• ANZROD includes Indigenous status - this improves calibration but should not be used for individual prognostication
• Monitor for disparities and implement equity-focused QI

Access:

• Coordinate with retrieval services for timely transfer from regional/remote areas
• Post-ICU follow-up support given access barriers

Evidence shows that adjusted ICU mortality is often equivalent for Indigenous patients once in the ICU (PMID: 37203411), but they present sicker and younger, reflecting upstream disparities. Our responsibility includes both excellent ICU care and advocacy for system improvements.

---

Viva 2: Quality Metrics and Accreditation

Opening Stem: "Your ICU is undergoing CICM accreditation review. The accreditation team asks about your quality and safety governance."

---

Examiner: What quality metrics do you monitor in your ICU?

Candidate: We monitor metrics across the Donabedian framework of Structure, Process, and Outcome:

Outcome Metrics:

• SMR (Standardized Mortality Ratio): Using ANZROD via ANZICS-CORE. Our current SMR is 0.92
• Hospital mortality: Captures deaths after ICU discharge
• ICU readmission rate: Within 48 hours; currently 4.5%
• Standardized Length of Stay (SLOS)

Process Metrics:

• CLABSI rate (per 1,000 catheter-days)
• VAP rate (per 1,000 ventilator-days)
• After-hours discharge rate
• Sepsis bundle compliance
• VTE prophylaxis compliance
• Early mobilization rates

Structure Metrics:

• Nursing ratio compliance (1:1 ventilated)
• Intensivist coverage hours
• Occupancy rates

Examiner: Your SMR is 0.92. What does that mean and how do you interpret it?

Candidate: An SMR of 0.92 means we have 8% fewer deaths than expected based on our case-mix, as predicted by ANZROD.

However, interpretation requires caution:

1. Funnel plots: We need to consider our case volume. On a funnel plot (PMID: 15568106), our SMR would be plotted against our admission numbers. If we're a small unit, even an SMR of 0.92 may not be statistically significantly different from 1.0.

2. Confidence intervals: An SMR of 0.92 with wide confidence intervals (e.g., 0.75-1.10) spanning 1.0 is not definitively "better than expected."

3. Peer comparison: ANZICS-CORE benchmarks us against similar units (metropolitan Level 2/3). We're performing in line with peers.

4. Trend monitoring: I would look at our SMR over time. A consistent SMR of 0.9-0.95 is reassuring; a rising trend would warrant investigation.

Examiner: What if your SMR was 1.25?

Candidate: An SMR of 1.25 would suggest 25% more deaths than expected and would require investigation:

Immediate Steps:

1. Verify data quality - are diagnoses and severity scores correctly coded?
2. Check case-mix changes - new patient populations or services?
3. Review timing of deaths - early vs late ICU deaths

Root Cause Analysis Approach:

1. Review all deaths in M&M meetings
2. Look for patterns - specific diagnoses, times, procedures
3. Assess structure factors - staffing, equipment, after-hours coverage
4. Assess process factors - bundle compliance, protocols

Potential Causes:

• Coding issues (most common explanation)
• Case-mix changes not captured
• Staffing inadequacies
• Protocol compliance failures
• After-hours discharge rates
• Delayed recognition of deterioration

Response:

• Report to hospital executive
• External review if concerns persist
• Targeted QI interventions
• Close monitoring of subsequent quarters

Examiner: What about NSQHS Standards? How do they relate to ICU?

Candidate: The 8 National Safety and Quality Health Service Standards are mandatory for hospital accreditation and apply to ICU:

Most Relevant Standards:

• Standard 8 (Recognising Acute Deterioration): We run the MET/RRT and are the destination for deteriorating patients. This standard assesses whether systems for recognition and response are effective.
• Standard 6 (Communicating for Safety): Clinical handover is critical in ICU. We use ISBAR for all handovers, including ICU to ward.
• Standard 3 (Infection Prevention): Our CLABSI, VAP, and CAUTI rates are monitored as part of this standard.
• Standard 4 (Medication Safety): High-risk medications like sedatives, vasoactives, and anticoagulants require robust systems.

ACHS Assessment:

• ACHS is the accrediting body for NSQHS
• They conduct hospital-wide assessments, now with short notice (48 hours)
• ICU is assessed within the hospital context
• They review clinical indicator data and interview staff and families

Examiner: How do you ensure your unit is always "survey-ready"?

Candidate: Survey-readiness is about embedding quality into daily practice:

Systems:

• Daily huddles addressing safety issues
• Real-time dashboards for key metrics
• Incident reporting with timely investigation
• Up-to-date policies accessible to all staff

Documentation:

• Contemporaneous, complete documentation
• M&M meeting minutes and action tracking
• Committee meeting records
• Training records and competencies

Culture:

• Staff understand their role in quality and safety
• Non-punitive reporting culture
• Regular education on standards
• Leadership walkrounds

Mock Surveys:

• Periodic internal audits against NSQHS standards
• Self-assessment tools
• Staff interviews and tracer methodology practice

This approach means we are continuously meeting standards, not preparing for a single survey event.
