澳大利亚监察员办公室对政府老年护理评估系统的自动化工具进行了调查，发现其存在严重缺陷。这个名为综合评估工具（IAT）的系统自2025年11月1日推出以来，已导致超过110万老年澳大利亚人的护理需求被错误评估1。监察员伊恩·安德森周一指出，根据现行法律，由IAT算法做出的自动化决定目前无法被推翻和改变，即使这些决定在临床上并不合适1。
调查发现，有关部门对IAT的工作机制完全缺乏公开说明1。卫生部门曾向评估提供商和公众不正确地声称IAT结果可以改变，直到2025年10月立法推出后才纠正这一说法1。为解决这些问题，监察员提出了10项建议，其中包括修改法律允许人工干预和推翻自动化决定1。
Australia's Commonwealth Ombudsman has launched a critical investigation into the Integrated Assessment Tool (IAT), revealing that the automated system used to evaluate aged care needs contains significant defects and produces unfair outcomes.1 Since its rollout on November 1, 2025, the tool has resulted in incorrect care assessments for over 1.1 million older Australians accessing aged care services through the home support system.1
A major concern identified by the Ombudsman is the legal constraint preventing human intervention in IAT decisions. Commonwealth Ombudsman Iain Anderson stated on Monday that "under current legislation, automated decisions made by the IAT algorithm cannot be overturned or changed, even when they are clinically inappropriate."1 The investigation also discovered that no public information exists explaining how the IAT determines its outcomes.1 Adding to the controversy, the Department of Health previously made incorrect claims to assessment providers and the public that IAT results could be modified, a position only corrected when legislation was introduced in October 2025.1
The Ombudsman has put forward 10 recommendations to address the system's failures, including legislative amendments that would allow human override of automated IAT decisions.1 In September 2024, The Guardian reported that departmental staff had warned the health minister of concerns just three days before the IAT's launch.1
