"What we're really trying to do is find out who's using our emergency rooms ... and find solutions," said Ann Kitchen, executive director of the group, which presented the report last week to the Travis County Healthcare District board.
The average emergency room visit costs $1,000. Hospitals and taxpayers paid the bill through government programs such as Medicare and Medicaid, Kitchen said.
"It's a pretty significant issue," said Dr. Christopher Ziebell, chief of the emergency department at University Medical Center at Brackenridge, which has the busiest ERs in the area.
Solutions include referring some frequent users to mental health programs or primary care doctors for future care, Ziebell said.
"They have a variety of complaints," he said. With mental illness, "a lot of anxiety manifests as chest pain."
