A Milwaukee woman's death is drawing attention to the controversy surrounding the practice of ambulance diversions. Tiffany Tate worked at the Medical College of Wisconsin when she suffered a. She worked just 350 yards from the area's best hospital for strokes, but the ambulance did not take her there for treatment.
Tate, 37, was taken to a different hospital with limited stroke care where she eventually died. An investigation by the Milwaukee Journal Sentinel looked into ambulance diversions and why it's happening in many of the country's largest cities.
Ambulance diversion is meant as a solution to address overcrowding in. Ambulances are directed to other facilities to relieve congestion.
But critics say the practice can cause overcrowding at other hospitals, lead to delayed medical care for patients, and can increase travel time to the hospital. As Tate's tragic case highlights, the practice can also have deadly consequences.
Investigative reporter John Diedrich from the Milwaukee Journal Sentinel notes that the practice began decades ago and was first only supposed to be a drastic measure to prevent overcrowding at hospitals. However, since then, it's become routine in many communities.
"This is not just a problem that happens in the ED but it's the result of inefficiencies and crowding throughout a system," Diedrich told CBSN. "It's really the result of hospitals being inefficient operations that haven't modernized."
Medical experts told Diedrich that Tate should have been taken to nearby Froedtert Hospital because it was the top stroke center in the area.
"They're able to do the level of stroke care that's only available at the highest level, not only in this area but across the country and that's really what she needed," Diedrich said. "To be clear, we don't know for sure whether she would have survived. Experts were clear on that but everybody agreed she would have had a much better chance."
What's more, he said that if Tate had arrived by a different means, she would have been treated there.
"People who drive up or walk up to an ED are required by federal law to be treated there so if she had been put in a wheelchair and been rolled over there or brought by a friend, they would have had to care for her," Diedrich said.
The Sentinel's review found that of the 25 largest cities in the U.S., 16 of them including nine of the largest, allow ambulance diversion of some kind, though rules governing when patients can be diverted vary widely.
"It's become routine in a lot of communities where one hospital will go on diversion and in response, other hospitals will also go on diversion and pretty soon you have a good chunk of your city on diversion," Diedrich said. "Then you have to force everybody open which happens sometimes or ambulance drivers are frustrated and having to drive around looking for a place to bring patients."
Some communities have voluntarily ended the practice of ambulance diversion, but there is currently no federal oversight on the issue. "There's no place in the federal government where this is watched or tracked," Diedrich said, "so that oversight is yet to come."
