Algorithmic Staffing Failures Linked to Resident Deaths at Leading Assisted-Living Chain Brookdale

Open on the AI Incident Database 1 news report Synced from the AIID API · record last edited 5 Sep 2026

What happened

Brookdale Senior Living's algorithm-based staffing system, "Service Alignment," reportedly left facilities understaffed, leading to critical incidents. For example, on April 21, 2021, Louise Walker, a resident at Brookdale's Jacksonville facility, died after falling and being left unattended for over two hours. State investigators cited Brookdale for medical neglect. The algorithm has been linked to multiple incidents of neglect, injuries, and deaths, prompting lawsuits.

Entries from the MIT AI Risk Repository coded to subdomain 7.3.

  • Reliability issues

    "Relying on general-purpose AI products that fail to fulfil their intended function can lead to harm. For example, general- purpose AI systems can make up facts (‘hallucination’), generate erroneous computer code, or pro...

  • Type 2: Bigger than expected

    Harm can result from AI that was not expected to have a large impact at all, such as a lab leak, a surprisingly addictive open-source product, or an unexpected repurposing of a research prototype.

  • Type 3: Worse than expected

    AI intended to have a large societal impact can turn out harmful by mistake, such as a popular product that creates problems and partially solves them only for its users.

  • Ethics and Morality Issues

    LMs need to pay more attention to universally accepted societal values at the level of ethics and morality, including the judgement of right and wrong, and its relationship with social norms and laws.
