The Winthrop Harbor Fire Department said staffing shortages, combined with the longer trip to Advocate Condell Medical Center in Libertyville, can leave ambulances unavailable for local calls. Patients whose conditions allow are being asked to consider closer hospitals.

The Waukegan Fire Department said its emergency medical protocols "have been immediately adjusted" in response to the bypass notice. In a Facebook post, the department said it remains committed to providing "seamless pre-hospital care without disrupting emergency response times."

"Effective today, all emergency transport ambulances will route patients to the nearest available alternative hospital," the post read, in part. "The leadership of the Waukegan Fire Department is working closely with regional health authorities and city leadership to monitor this situation and keep the community informed."

Vista East continues to accept walk-in patients at its emergency room.

The EMS bypass is the latest setback for the hospital. In October, IDPH revoked Vista Medical Center East's designation as a Level II trauma center, limiting its ability to treat certain serious injuries. In July, the hospital faced foreclosure proceedings over $2 million in back taxes owed to Lake County. Late last year, the hospital ended its labor and delivery and obstetrics and gynecology services.

The bypass means residents in Waukegan and surrounding communities will face longer transport times for emergency care, a particular concern for patients with time-sensitive conditions. Local fire officials said they are monitoring the situation and will keep the community informed as it develops.
