The Instituto Mexicano del Seguro Social ordered an independent collegial clinical audit to review each fatality. External specialists will conduct the examination to determine whether hospital-associated infections caused or contributed to the deaths of the neonates and if avoidable failures occurred. To ensure the process remains reliable and independent, the hospital director and the head of the neonatal intensive care unit were removed from their positions while the audit proceeds. According to Zoé Robledo, the results of this review will be communicated first to the affected families.
The fatalities took place between June and August and have been linked by authorities to the bacteria Klebsiella pneumoniae and the fungus Candida albicans. Parents such as Marcela and Gerardo spoke publicly regarding the clinical deterioration of their infants after discovering bacterial presence during treatment. The Secretaría de Salud and the Instituto Mexicano del Seguro Social (IMSS) informed about the cases registered in the Unidad de Cuidados Intensivos Neonatales of the Hospital de Gineco-Obstetricia del Centro Médico Nacional de Occidente, in Guadalajara, Jalisco, related to infections by Klebsiella pneumoniae and Candida albicans. Relatives of three newborns who lost their lives after staying in the Unidad de Cuidados Intensivos Neonatales of the Centro Médico de Occidente, in Guadalajara, initiated a legal process toward the Instituto Mexicano del Seguro Social (IMSS) and the Fiscalía General de la República (FGR).

Federal health sector command launches epidemiological investigation
To establish the exact origin of the pathogens, the Instituto Mexicano del Seguro Social escalated the epidemiological investigation. All identified microorganisms will undergo analysis at the Instituto Nacional de Diagnóstico y Referencia Epidemiológica (INDRE). Concurrently, Zoé Robledo reached an agreement with Secretary of Health David Kershenobich and Cofepris federal commissioner Víctor Hugo Borja to establish a joint Comando Operativo del Sector Salud. This task force will enforce standardized epidemiological surveillance, early outbreak alerts, periodic hygiene reviews, and strict protocols for evaluating antimicrobial resistance and severe cases. The authorities indicated that this work is developed in accordance with the IMSS Guideline for the Comprehensive Care of Hospital Outbreaks of Healthcare-Associated Infections (IAAS). Concurrently, reinforced measures inside the unit include taking cultures, exhaustive cleaning and disinfection, delimitation of areas within the unit, permanent supervision of hygiene measures, and coordination with the health authorities of Jalisco, with the Secretaría de Salud and the IMSS stating that their priority is to fully clarify what happened and protect the health and safety of newborns.
“Vamos a llegar al fondo”, aseguró Robledo, adding that where system failures are confirmed, the institution will provide reparations.
