In Minas Gerais, a state run AI triage platform called Core MG went live 18 days before Rebeca Molina, 32, died after a five day wait for an ICU bed. Her family is now asking who, if anyone, can override the number.
When Rebeca Cardoso Tenente Molina's doctors tried to move her into intensive care, the system that coordinates ICU beds across the Brazilian state of Minas Gerais said not yet. For five days, the algorithm kept assigning her a severity score that placed her behind other patients, even as her condition deteriorated. She died on June 6, 2026, in a hospital roughly 300 kilometers from where she had first been admitted, after the bed her family had spent days fighting for finally opened.
Molina was 32, a psychologist from Mar de Espanha. On June 2, she had gone to a hospital in São João Nepomuceno, in the Zona da Mata region, with what was initially diagnosed as gallstones. Within hours she was intubated and hemorrhaging. Her family filed an emergency legal action to force a transfer to a hospital with an available ICU bed. That bed only opened on June 6 at a facility in Oliveira, about 300 kilometers away, according to G1, the regional arm of Brazil's Globo network. The family chartered a private plane to move her. She did not survive.
Her death certificate lists septic shock as the cause. Her treating physicians had also raised a possible botulism diagnosis, and the official cause remains under investigation, according to the same G1 report from June 11, 2026.
The platform that failed to move Molina faster is called Core-MG, short for Central de Operações para Regulação Estadual, or State Regulation Operations Center. It is a state-run, AI-assisted system that ranks ICU transfer requests across Minas Gerais's public hospital network. It went live on May 19, 2026, less than three weeks before Molina's hospitalization, replacing an older platform called SUS Fácil, according to the official launch release from Agência Minas, the state government's news service.
Molina's twin sister, Sâmela Cardoso Tenente Furtado, who is also the family's lawyer, says the platform is what killed her. In an interview with G1, Furtado said the system assigned her sister a clinical severity score of roughly 6.8 out of 10, even as bedside physicians were trying to flag her as a 10. The score, in the family's account, did not rise as new test results came in. Lower-scored patients kept moving ahead of her on the transfer queue. "The doctors lost the autonomy to decide if a patient is very seriously ill," Furtado told G1.
That specific score, 6.8 versus 10, is the family's allegation, not a figure the state has confirmed came from the system. The Secretaria de Estado de Saúde de Minas Gerais (SES-MG), the state health agency that operates Core-MG, has not disclosed the formula the platform uses to compute its priority indicator, and no independent audit of its triage decisions has been published.
In a written response to G1, SES-MG defended the platform's handling of the case. The agency said Molina was registered in the system immediately upon request, that the bed search expanded beyond the Juiz de Fora region to other areas including the supplementary private network, and that hospital choice is driven by clinical bed availability rather than proximity. The agency added that Core-MG "did not alter the assistance criteria or the search methodology." That response is a position from the operator of the system under scrutiny, not an independent finding.
The structural question Molina's death exposes is whether any human actor in the system can override it. Core-MG was built to be assistive, not autonomous. Regulator physicians are still supposed to evaluate each case, and the platform surfaces required clinical fields and care protocols to inform their decisions, according to the state's launch documentation. But the system produces a numeric severity score, and the family's allegation is that the score, not the doctor's judgment, governed the queue. If that is how the platform operates in practice, the override is theoretical.
The launch numbers published by the state underscore the system's scale. Average daily Core requests have risen to 3,013 from 2,562 under SUS Fácil, a 17.6 percent increase, and regulated admissions to 2,047 per day from 1,929, a 6.1 percent increase, according to the Agência Minas release. A bed map is updated three times a day, and the platform integrates with CadSUS, Brazil's national health card registry, and CNES, the National Registry of Health Establishments. More than 200 regulator physicians are now using the tool.
A larger question sits underneath those figures. Core-MG was live for less than three weeks before a family publicly alleged that its scoring mechanism had outranked a bedside clinician and a patient died. The state agency that built the system is also the agency investigating the case. The platform's algorithmic detail is not public. No external review of its triage decisions has been released. The family has signaled legal action.
For now, the test of any such system is the same one Molina's family is putting to the state of Minas Gerais: when a qualified doctor says a patient is critical, and the number says otherwise, who gets to decide?
