Infection Prevention and Outbreak Management in Aged Care

Infection prevention and control (IPC) saves lives in aged care. Older Australians living in residential care are among the most vulnerable populations to healthcare-associated infections — their immune systems are compromised by age, chronic disease, and frailty, and the communal living environment creates transmission pathways that do not exist in the general community. COVID-19 made this reality undeniable. The pandemic exposed systemic gaps in IPC preparedness across the sector, and the regulatory response has been permanent: the Aged Care Act 2024 and the Strengthened Quality Standards now impose IPC obligations that go far beyond what was expected before 2020. Quality Standard 4 (The Environment) requires providers to maintain safe, hygienic environments, while Quality Standard 5 (Clinical Care) mandates clinical governance over infection prevention, outbreak management, and antimicrobial stewardship. Every facility must have a designated IPC lead with appropriate qualifications — this is not optional, and the ACQSC will ask for evidence of the appointment during assessment contacts.

Effective IPC begins with surveillance — the systematic collection, analysis, and interpretation of infection data across your facility. Without surveillance, you are reacting to outbreaks after they have taken hold rather than detecting them at the earliest possible point.

At minimum, providers should be tracking respiratory infections (including influenza, COVID-19, and RSV), gastroenteritis, urinary tract infections, skin and wound infections, and multi-resistant organisms (MROs). Each infection event should be recorded with the resident's location (unit or wing), onset date, organism (if known), and outcome. This data feeds both your internal quality improvement program and mandatory reporting.

The critical threshold that every IPC lead must know: two or more cases of the same infection type in the same unit within 72 hours constitutes an outbreak. This is the point at which your response escalates from routine surveillance to active outbreak management. Manual surveillance — spreadsheets, paper logs, or retrospective chart reviews — frequently misses this threshold because the data is not aggregated in real time. By the time someone notices a pattern, the 72-hour window has passed and the outbreak has spread.

Automatic outbreak detection changes this equation. When infection events are recorded digitally with structured data (infection type, unit, date), the system can continuously monitor for clusters that meet the outbreak threshold and alert the IPC lead immediately. This is the difference between detecting an outbreak at 2 cases and detecting it at 8.

Once an outbreak is declared, the response must be rapid, structured, and documented. The first obligation is notification: outbreaks must be reported to your local Public Health Unit (PHU) and to the Aged Care Quality and Safety Commission (ACQSC). The PHU notification triggers public health support, including access to epidemiological advice, laboratory testing coordination, and — in serious outbreaks — on-site public health response. The ACQSC notification ensures the regulator is aware and can assess whether the provider's response is adequate.

Notification should occur within 24 hours of the outbreak being identified. Delays in notification are a compliance failure and, more importantly, delay the public health support that can help contain the outbreak.

Once notified, the outbreak management workflow should follow a structured sequence: implement immediate control measures (isolation, enhanced cleaning, PPE escalation, visitor restrictions), establish a line list tracking all confirmed and suspected cases, conduct daily surveillance to monitor for new cases, communicate with families and representatives of affected residents, and document every decision and action taken.

Family communication during outbreaks is both a regulatory obligation and a trust issue. Families expect to be informed promptly when their loved one is affected by or at risk from an outbreak. Your communication plan should include initial notification, regular updates, and clear information about what measures are in place.

Outbreak closure requires meeting defined criteria — typically no new cases for a period equal to twice the incubation period of the organism involved. The closure must be formally documented, and a post-outbreak review conducted to identify lessons learned and systemic improvements. Where an outbreak has resulted in serious harm to a resident — including death, hospitalisation, or significant clinical deterioration — the incident may be reportable under the Serious Incident Response Scheme (SIRS).

Hand hygiene is the single most effective measure for preventing healthcare-associated infections. The national benchmark for hand hygiene audit compliance in aged care is 80% — meaning at least 80% of observed hand hygiene opportunities must be performed correctly.

Achieving and sustaining this target requires a structured audit program. Audits should be conducted using the WHO Five Moments methodology: before touching a resident, before a clean or aseptic procedure, after body fluid exposure risk, after touching a resident, and after touching a resident's surroundings. Audits should be conducted regularly (monthly at minimum), across all shifts (not just day shift), and by trained auditors who understand the methodology.

When audit results fall below 80%, corrective actions must be implemented and documented. Common interventions include targeted education for units or individuals with low compliance, placement review for hand hygiene stations and alcohol-based hand rub dispensers, and visual prompts at point of care. The corrective action loop — audit, identify gap, intervene, re-audit — must be documented as evidence for Quality Standard 5.

Environmental audits complement hand hygiene by assessing cleaning standards, equipment decontamination, waste management, and laundry processes. High-touch surfaces in communal areas, bathrooms, and clinical spaces should be included in every audit round. Environmental audit findings should feed back to your facilities management team with specific, time-bound corrective actions.

Antimicrobial resistance is one of the most serious threats to healthcare globally, and aged care is a significant contributor. Residents in aged care facilities receive antibiotics at high rates — often empirically, without culture and sensitivity testing, and sometimes for prolonged courses that are not clinically justified. Every unnecessary or inappropriate antibiotic course increases the risk of resistant organisms emerging within your facility.

Under the Strengthened Quality Standards, providers are required to have an antimicrobial stewardship (AMS) program. At a practical level, this means tracking every antimicrobial course prescribed within the facility — the indication, the agent, the duration, and whether it was reviewed. AMS programs should monitor whether prescribing aligns with current Therapeutic Guidelines, whether courses are reviewed within 48-72 hours of initiation, and whether cultures are collected before empiric therapy where clinically indicated.

The IPC lead and the facility's medical practitioners share responsibility for antimicrobial stewardship. Regular reporting on antibiotic usage rates, appropriateness of prescribing, and resistance patterns should be presented to the clinical governance committee and, through that committee, to the governing body. This is not a clinical nice-to-have — it is a regulatory expectation, and the ACQSC will look for evidence of an active AMS program during assessment contacts.

Statura Care's Infection Prevention & Control module is purpose-built for the IPC obligations under the Aged Care Act 2024. The module includes a surveillance register that captures every infection event with structured data — infection type, organism, unit, onset date, and outcome — enabling real-time monitoring across the facility. Automatic outbreak detection continuously analyses surveillance data against the 72-hour threshold and alerts the IPC lead the moment a cluster is identified, eliminating the risk of missed outbreaks.

The outbreak management workflow guides your team from notification through to closure: PHU and ACQSC notification templates with deadline tracking, line list management, daily case monitoring, family communication logs, and post-outbreak review documentation. Hand hygiene audits are built into the module with WHO Five Moments methodology, compliance tracking against the 80% target, and corrective action workflows when results fall short. Antimicrobial stewardship tracking captures every antibiotic course, flags courses that exceed recommended duration, and generates usage reports for your clinical governance committee.

All IPC data feeds into Quality Standards evidence for Standard 4 (The Environment) and Standard 5 (Clinical Care), and outbreak-related incidents that result in serious harm automatically link to the SIRS module for reportable incident management.
