It was at least her third visit to Los Angeles County's public Martin Luther King Jr.-Harbor Hospital in as many days. "You have already been seen, and there is nothing we can do," a nurse told her.
Minutes later, the 43-year-old mother of three collapsed on the floor screaming in pain and began vomiting blood. Employees ignored her, and soon she was dead.
Now state and federal regulators are threatening to close the hospital or pull its funding unless it can be improved, and Rodriguez has become a symbol of everything wrong with the facility derisively known as "Killer King."
After she collapsed, surveillance cameras show that Rodriguez was left on the floor.
Nurses walked past her. A janitor cleaned up around her. No one did anything until police were called to take her away. They did not get far before she went into cardiac arrest and died.
"This needs to stop," state Health Services Director Sandra Shewry said Thursday as the agency moved to revoke the hospital's license. "We're doing this in response to the egregious incidents that have come to light in the last six weeks."
The hospital, formerly known as Martin Luther King Jr.-Drew Medical Center, was built after the 1965 Watts riot to bring health care to poor, minority communities in south Los Angeles.
But it had been plagued by patient deaths blamed on sloppy nursing care, among other things. The county tried over the last few years to correct the problems with a multimillion-dollar rescue effort, disciplining workers, reorganizing management, closing the trauma unit and reducing the number of beds from 200 to 48.
After Rodriguez's death, federal reports showed those efforts were failing and patients were in "immediate jeopardy." Of the 60 cases reviewed between February and June, more than a quarter received substandard care, according to the U.S. Centers for Medicare and Medicaid Services.
In February, a brain tumor patient languished in the emergency room for four days before his family drove him to another hospital for emergency surgery. A pregnant woman who complained of bleeding was given a pregnancy test and left, only to return three days later and have a miscarriage after waiting more than four hours to see a doctor.
The findings have sent county officials scrambling to improve care before a federal inspection due by Aug. 15 that could determine whether the hospital keeps its federal funding. The county might close the facility without that money.
"I'm losing hope," Zev Yaroslavsky, member of the county Board of Supervisors that oversees King-Harbor, told hospital managers earlier this week. "We need to be prepared for the worst-case scenario."
On Friday, the county's Department of Health Services released a contingency plan to deal with closing hospital departments and relocating patients if they must. The plan, which also lays out how the hospital could eventually be reopened if a private partner is found, will be presented to the Board of Supervisors on Tuesday, said Bruce Chernof, director of the department.
