Broken system? Pain relief for fractures differs by race/ethnicity

Femoral fracture

Data collected by a multi-institutional research team show that kids’ pain from long bone fractures may be managed differently in the emergency department depending on the child’s race and ethnicity.

Children who experience broken bones universally feel pain. However, a new multi-institutional study presented at the American Academy of Pediatrics (AAP) 2018 National Conference & Exhibition suggests that emergency treatment for this pain among U.S. children is far from equal. Data collected by the research team show that kids’ pain may be managed differently in the emergency department depending on the child’s race and ethnicity. In particular, while non-Latino black children and Latino children are more likely to receive any analgesia, non-white children with fractured bones are less likely to receive opioid pain medications, even when they arrive at the emergency department with similar pain levels.

“We know from previously published research that pain may be treated differentially based on a patient’s race or ethnicity in the emergency department setting. Our prior work has demonstrated that racial and ethnic minorities are less likely to receive opioid analgesia to treat abdominal pain, even when these patients are diagnosed with appendicitis,” says study leader Monika K. Goyal, M.D., MSCE, assistant division chief and director of Academic Affairs and Research in the Division of Emergency Medicine at Children’s National Health System. “Emergency departments delivering evidence-based care should treat all pediatric patients consistently. These findings extend our work by demonstrating that children presenting with long bone fractures also experience differential treatment of pain based on their race or ethnicity.”

The AAP calls appropriately controlling children’s pain and stress “a vital component of emergency medical care” that can affect the child’s overall emergency medical experience. Because fractures of long bones – clavicle, humerus, ulna, radius, femur, tibia, fibula – are commonly managed in the emergency department, the research team tested a hypothesis about disparities in bone fracture pain management.

They conducted a retrospective cohort study of children and adolescents 21 and younger who were diagnosed with a long bone fracture from July 1, 2014, through June 30, 2017. They analyzed deidentified electronic health records stored within the Pediatric Emergency Care Applied Research Network Registry, which collects data from all patient encounters at seven pediatric emergency departments.

During that time, 21,642 patients with long bone fractures met the study inclusion criteria and experienced moderate to severe pain, rating four or higher on a 10-point pain scale. Some 85.1 percent received analgesia of any type; 41.5 percent received opioid analgesia. Of note:

  • When compared with non-Hispanic white children, minority children were more likely to receive pain medication of any kind (i.e. non-Latino black patients were 58 percent more likely to receive any pain medication, and Latino patients were 23 percent more likely to receive any pain medication).
  • When compared with non-Latino white children, minority children were less likely to receive opioid analgesia (i.e., non-Latino black patients were 30 percent less likely to receive opioid analgesia, and Latino patients were 28 percent less likely to receive opioid analgesia).

“Even though minority children with bone fractures were more likely to receive any type of pain medication, it is striking that minority children were less likely to receive opioid analgesia, compared with white non-Latino children,” Dr. Goyal says. “While it’s reassuring that we found no racial or ethnic differences in reduction of patients’ pain scores, it is troubling to see marked differences in how that pain was managed.”

Dr. Goyal and colleagues are planning future research that will examine the factors that inform how and why emergency room physicians prescribe opioid analgesics.

Potential to replace race as a risk factor for kidney-transplant failure

Right now, more than 100,000 adult and pediatric patients in the U.S. are waiting for a life-saving kidney donation. Thirteen of them die each day while awaiting a transplant. However, a significant portion of kidneys from deceased donors are discarded because they literally don’t make the grade – a scoring system known as the kidney donor profile index (KDPI) that aims to predict how long a donor kidney will last in an intended recipient based on a variety of factors, including the donor’s age, size and health history.

Ethnicity and race are also part of that scoring system, explains Marva Moxey-Mims, M.D., FASN, chief of the Division of Nephrology at Children’s National Health System. That’s partly because research over the years has suggested that kidneys from certain racial groups, including African-Americans, may not have the same longevity as those from other groups.

But race might not be the right marker to consider, Dr. Moxey-Mims counters. More recent studies have shown that a particular gene known as APOL1 might better predict risk of kidney-transplant failure. APOL1 high-risk variants are associated with a wide range of kidney diseases, with retrospective studies suggesting that they could be a key cause of failure in some donated kidneys. Although this gene is found almost exclusively in people of recent African descent, only about 13 percent of that population has high-risk APOL1 variants that might cause kidney problems.

“Instead of putting all African-American donor kidneys in one proverbial ‘bucket,’ we might be able to use this gene to determine if they truly carry a higher risk of early failure,” Dr. Moxey-Mims says.

To more definitively confirm whether this gene could be used as a proxy for heightened kidney-failure risk, Dr. Moxey-Mims and colleagues across the country are participating in the APOL1 Long-Term Kidney Transplantation Outcomes Network (APOLLO) study, she and Dr. Barry Freedman explain in a perspective published online April 27, 2018, in Clinical Journal of the American Society of Nephrology. The APOLLO study will tap people accessing the hundreds of transplant centers scattered across the nation, prospectively genotyping deceased and living African-American kidney donors as well as kidney-transplant recipients to assess whether they carry high-risk APOL1 gene variants. Living donors and transplant recipients will be followed for years to gauge how their kidneys fare over time.

The researchers, Dr. Moxey-Mims explains, hope to answer whether the APOL1 high-risk gene variants in donor kidneys could replace race as a risk factor when calculating the KDPI score and whether recipients’ own APOL1 gene variants impact transplant failure risk. They also hope to better understand the risk to living donors. “If a living donor has an increased risk of kidney failure,” she adds, “he or she can make a more educated decision about whether to donate a kidney.”

Dr. Moxey-Mims plays a pivotal role as the chair of the study’s steering committee, a group made up of the study’s principal investigators at all 13 clinical sites and the Data Coordinating Center, as well as the program officials from the National Institutes of Health funding institutes (National Institute of Diabetes and Digestive and Kidney Diseases, National Institute of Allergy and Infectious Diseases, and National Institute on Minority Health and Health Disparities). She will play a key part in helping to ensure that the study stays on track with recruitment goals, as well as publicizing the study at national meetings.

The study also includes a Community Advisory Council, a group made up of stakeholders in this study: 26 African-Americans who either have donated a kidney, received a kidney donation, are on dialysis awaiting a kidney transplant, or have a close relative in one of those categories. This group has helped to steer the study design in multiple ways, Dr. Moxey-Mims explains. For example, they have worked with study leaders to simplify the language on consent forms, helped to delineate which data study participants might want to receive when the study is completed, and helped to publicize the study in their communities by giving talks at churches and other venues.

Eventually, Dr. Moxey-Mims says APOLLO study researchers hope that clarifying the role of the APOL1 gene in kidney-transplant failure could lead to fewer discarded kidneys, which could boost the number of available kidneys for patients awaiting transplants.

“Down the road, the pool of patients awaiting transplant might have access to more kidneys because available organs aren’t getting a bad score simply because the donor is African-American,” she says. “We hope this might shorten the wait for some patients and their families who are desperate to get that call that a kidney is finally available.”
