One patient's death changed the course of Dr. Lilia Cervantes' career. The patient, Cervantes says, was a woman from Mexico with kidney failure who repeatedly visited the emergency room for more than three years. In that time, her heart had stopped more than once, and her ribs were fractured from CPR. The woman finally decided to stop treatment because the stress was too much for her and her two young children. Cervantes says she died soon after.
Kidney failure, or end-stage renal disease, is treatable with routine dialysis every two to three days. Without regular dialysis, which removes toxins from the blood, the condition is life threatening: Patients' lungs can fill up with fluid, and they're at risk of cardiac arrest if their potassium level gets too high.
But Cervantes' patient was undocumented. She didn't have access to government insurance, so she had to show up at the hospital in a state of emergency to receive dialysis.
Cervantes, an internal medicine specialist and a professor medicine at University of Colorado in Denver, says the woman's death inspired her to focus more on research. "I decided to transition so I could begin to put the evidence together to change access to care throughout the country," she says.
Cervantes says emergency-only dialysis is harmful to patients: The risk of death for someone receiving dialysis on an emergency basis is 14 times higher than someone getting standard care, she found in research published in February. Cervantes' newest study, published Monday in the Annals of Internal Medicine, shows these cyclical emergencies harm health care providers, too. "It's very, very distressing," she says. "We not only see the suffering in patients, but also in their families."
There are an estimated 6,500 undocumented immigrants in the U.S. with end-stage kidney disease. Many of them can't afford treatment or private insurance, and are barred from Medicare or Medicaid. This means the only way they can get dialysis is in the emergency room.
Cervantes and her colleagues interviewed 50 healthcare providers in Denver and Houston and identified common concerns among them. The researchers found that providing undocumented patients with suboptimal care because of their immigration status contributes to professional burnout and moral distress.
"Clinicians are physically and emotionally exhausted from this type of care," she says.
Cervantes says the relationships clinicians build with their regular patients conflicts with the treatment they have to provide, which might include denying care to a visibly ill patient, because their condition was not critical enough to warrant emergency treatment.
"You may get to know a patient and their family really well," she says. Providers may go to a patient's restaurant, or to family gatherings such as barbacoas or quinceañeras.
"Then the following week, you might be doing CPR on this same patient because they maybe didn't come in soon enough, or maybe ate something that was too high in potassium," she says.
Other providers, Cervantes says, report detaching from their patients because of the suffering they witness. "I've known people that have transitioned to different parts of the hospital because this is difficult," she says.
Melissa Anderson, a nephrologist and assistant professor at the Indiana University School of Medicine in Indianapolis who was not involved in Cervantes' study, says Cervantes research matches her own experience. She says that when she worked at a safety net hospital in Indianapolis, patients would come to the ER when they felt sick. But some hospitals would not provide dialysis until their potassium was dangerously high.
To avoid being turned away when their potassium level was too low, she says, patients in the waiting room would drink orange juice, which contains potassium, putting themselves at risk of cardiac arrest.
"That's Russian roulette," Anderson says. "That was hard for all of us to watch."
Anderson eventually stopped working at that hospital, and like Cervantes, has also worked on research and advocacy efforts to change how undocumented immigrants with kidney failure are treated. "I practically had to take a class in immigration to understand what's going on," she says. "Physicians just don't understand it, and we shouldn't have to."
Providers in Cervantes' study also worried that these avoidable emergencies strain hospital resources — clogging emergency departments when undocumented patients could simply receive dialysis outside the hospital — and about the cost: Emergency-only hemodialysis costs nearly four times as much as standard dialysis, according to a 2007 study from researchers at Baylor College of Medicine.
Those costs are often covered by taxpayers through emergency Medicaid, which pays for emergency treatment for low-income individuals without insurance. In a study published in Clinical Nephrology last year, Anderson and her colleagues found that at one hospital in Indianapolis, the state paid significantly more for emergency-only dialysis than it did for more routine care.
Areeba Jawed, a nephrologist in Detroit who has performed her own survey research into this issue, said many providers don't understand how much undocumented immigrants actually contribute to society, while receiving few of the societal benefits. "A lot of people don't know that undocumented immigrants do pay taxes," she says. "There's a lot of misinformation."
"I think there are better options," says Jawed, who has treated undocumented patients there and in Indianapolis.
To work around this problem, some hospitals simply provide charity care to cover regular dialysis for undocumented patients. But Cervantes argues that a better solution is a policy fix. States are allowed by the federal government to define what qualifies as an emergency.
"Several states, like Arizona, New York and Washington, have modified their emergency Medicaid programs to include standard dialysis for undocumented immigrants," she says.
Illinois covers routine dialysis and even passed a law allowing undocumented immigrants to receive kidney transplants, she points out.
"Ideally, we could come up with federal language and make this the national treatment strategy for undocumented immigrants," Cervantes says.
Ultimately, Cervantes says providers don't want to treat undocumented patients differently. "At the end of the day, clinicians become providers because they want to provide care for all patients," she says.
