Mobile stroke units debuted in two U.S. cities during the past year, and already they are saving critical minutes when it comes to treating stroke patients, according to a pair of studies released Wednesday.
The mobile units, each of which resemble an ordinary ambulance and cost about $1 million, are essentially specialized emergency rooms on wheels. They include unique equipment, such as a portable CT scanner to help determine what type of stroke a patient is experiencing and how best to treat it. They also include lab testing equipment and clot-busting drugs that can greatly improve the prognosis for patients who receive them soon after the onset of symptoms. In addition, the units are staffed with a critical care nurse and a paramedic, as well as a CT technology expert. In Cleveland, where one of the units began last summer, two-way video conferencing also allows a doctor to remotely evaluate a patient.
“This is a situation where every minute counts,” said M. Shazam Hussain, head of the stroke program at the Cleveland Clinic, which recently named the mobile unit as a top medical innovation for 2015. “Time is critically important. You lose something like 2 million brain cells a minute during a stroke.”
Researchers in Cleveland, where the stroke unit operates from 8 a.m. to 8 p.m. each day, examined the cases of dozens of patients treated by the mobile unit vs. those who went to the emergency room. They found that, on average, patients received a CT scan more than 20 minutes faster when using the mobile stroke unit. They also noted a “significant reduction” in treatment time — 64 minutes when the mobile unit responded versus 104 minutes in the emergency room.
