Brazilian Woman Dies After AI System Delays ICU Transfer

What happened

Rebeca Cardoso Tenente Molina, a 32-year-old woman, was hospitalized on June 2, 2026 in São João Nepomuceno, Minas Gerais with what was believed to be gallstones. Her condition rapidly deteriorated and she requested transfer to an intensive care unit.

The State Health Department of Minas Gerais had implemented Core-MG, a new AI-powered hospital management system, in May 2026 to manage hospital bed allocation. According to her family, the system assigned Molina an inaccurately low severity score of 6.8 when her condition warranted a score of 10, causing a five-day delay in her transfer to an ICU located approximately 186 miles away in Oliveira.

Molina died shortly after arriving at the ICU. Her cause of death is listed as septic shock, though doctors were investigating whether other conditions such as botulism may have contributed.

Reported impact

Molina's family and her twin sister, lawyer Sâmela Cardoso Tenente Furtado, alleged that the five-day delay in ICU transfer was fatal and directly caused by the AI system's failure to accurately assess her deteriorating condition.

The family argued that Core-MG deprived doctors of medical autonomy by automatically determining patient priority levels, with Furtado stating: "What we saw was that doctors lost the autonomy to decide if a patient is very seriously ill."

Index analysis

The family contended that Core-MG failed to update Molina's severity level despite worsening test results continuously feeding into the system, preventing her from advancing in the priority queue even as her condition worsened.

The State Health Department defended Core-MG by stating that the system had not changed the criteria for managing care and that bed allocation considers both geographic proximity and the availability of beds according to clinical needs, not only the AI-assigned score.

Governance controls

The family pursued emergency legal action against the hospital system to compel a faster transfer, though the litigation did not prevent the delay.

Molina's family engaged legal representation, with her sister serving as a lawyer advocating for the case.
