Concerns Rise Over Aged Care Funding Assessment Tool's Algorithm

The Integrated Assessment Tool (IAT) was introduced in November 2025 as part of the Australian government's Support at Home reforms, designed to assess eligibility and allocate funding for aged care services. However, reports indicate that the algorithm frequently under-assesses the needs of older individuals, raising significant concerns about its effectiveness and fairness.

During a recent hearing, Department of Health, Disability and Ageing officials confirmed that the government is seeking advice on reinstating the ability for assessors to override incorrect outcomes generated by the IAT. This decision follows criticism from various stakeholders, including Greens senator Penny Allman-Payne, who questioned the legislative basis for removing the override function. Robert Day, the department’s first assistant secretary, stated that the current system relies on objective outcomes without discretionary elements, which has led to concerns about the lack of human oversight in the assessment process.

Liberal senator Paul Scarr has also expressed alarm regarding the legality of preventing assessors from overriding algorithmic decisions. He noted that the user manual for the IAT refers to rule 81-10 of the Aged Care Rules, which does not explicitly mention any prohibition on overrides. Scarr described the situation as "very disturbing," emphasizing that automated decision-making should not occur in inappropriate circumstances.

The removal of the override function has led to a significant increase in requests for internal reviews of IAT outcomes, with 834 requests logged since the tool's introduction. Allman-Payne highlighted that the average review process takes over two months, leaving vulnerable individuals without timely recourse if the algorithm misclassifies their care needs. She pointed out that the lack of human oversight is particularly detrimental for those with degenerative conditions, such as motor neurone disease, whose assessed needs have been downgraded.

Independent senator David Pocock raised concerns about the effectiveness of the assessment process, questioning the rationale behind not allowing experienced assessors to correct errors. He emphasized the importance of human judgment in ensuring that care needs are accurately assessed.

Department officials acknowledged the challenges posed by the IAT, stating that there is currently no mechanism to track how often assessors have raised concerns about the tool's outcomes. The inquiry revealed that the legal and regulatory framework supporting the automation of classifications and the removal of human oversight is questionable.

Critics, including Allman-Payne and Scarr, argue that the IAT's reliance on algorithmic assessments without human intervention is fundamentally flawed and poses risks to the well-being of older Australians. They contend that the system's design undermines the expertise of assessors and could lead to inadequate care for those in need.

• “It’s clear that removing human override and letting the algorithm rip is having detrimental effects on older people.” — Penny Allman-Payne, Greens Senator

• “What’s the point of having someone who’s experienced … and not giving them the ability to actually make a change if they do see an error?” — David Pocock, Independent Senator

The Guardian

• “There was no suggestion that there would be these guidelines preventing overruling of assessments.” — Paul Scarr, Liberal Senator

The ongoing discussions surrounding the IAT highlight the critical need for a balanced approach that incorporates both technological advancements and human oversight in the assessment of aged care needs.
