Heightened federal immigration enforcement in Los Angeles coincided with a sharp drop in ER visits among foreign-born patients — but a rise in hospital admissions, suggesting people are waiting until they're critically ill to seek care. A separate survey found nearly half of Latino patients who feared seeking emergency care had already delayed treatment. The findings signal a growing public health concern tied to immigration policy.
Two new studies published in JAMA Network Open paint a troubling picture of how immigration enforcement is reshaping healthcare-seeking behavior. Following a June federal ICE operation in Los Angeles, emergency department visits among foreign-born patients at three LA County safety-net hospitals dropped significantly — by more than 20% in the first four weeks — while inpatient admissions climbed, suggesting patients are arriving sicker and in greater need of acute care.
The declines were most pronounced among Mexican-born and Central or South American-born patients, but also extended to Asian-born patients. A concurrent survey of 345 ED patients across San Francisco and Houston found that Spanish-speaking Latino respondents were far more likely than non-Latinos to fear seeking care — and nearly half of those who expressed fear had already delayed emergency treatment.
By the Numbers:
Why it matters: When fear keeps patients out of ERs, they show up later — and sicker. That means worse outcomes, higher costs, and strained hospital systems. For health systems in immigrant-dense markets, this isn't just a policy issue; it's already affecting patient volumes and care delivery.
