Despite effort, there’s a racial disparity in sepsis care

Hospitals with more black patients saw smaller increases in compliance with new sepsis protocols than those that treat mainly white patients, a new study shows.

The findings highlight a need to evaluate the effects of quality improvement projects for minority groups, researchers say.

The New York Sepsis Initiative launched in 2014 with the goal of improving prompt identification and treatment of sepsis. The new study in Health Affairs, finds that while the program has improved care over all, racial and ethnic disparities in the implementation of best-practice protocols remain.

Sepsis is a life-threatening condition that occurs when the body’s extreme response to an infection triggers a chain reaction, says Mitchell Levy, a professor of medicine and chief of the division of Pulmonary, Critical Care and Sleep Medicine at Brown University’s Warren Alpert Medical School. “Even with the best care, the mortality rate is between 15 and 25 percent.”

Sepsis protocols

Early identification and treatment of sepsis is essential for saving lives. The New York Sepsis Initiative’s protocols codified the multi-stage best practices for sepsis identification and treatment.

The research shows that during the first 27 months of the initiative, the percent of patients who received the complete 3-hour-long, best-practice protocol increased from 60.7 percent to 72.1 percent. At the same time, in-hospital mortality rates for sepsis patients decreased from 25.4 percent to 21.3 percent.

However, the new paper highlights a disparity in sepsis care between black and white patients.

“Racial and ethnic minority groups can get left behind.”

Specifically, during the first 27 months of the initiative, black patients only experienced an increase of 5.3 percentage points in the completion of the best-practice protocol, while white patients experienced an increase of 14 percentage points. Hispanic and Asian patients experienced an increase of 6.7 and 8.4 percentage points respectively.

Being aware of these disparities is critical because the Centers for Medicare and Medicaid Services is considering tying sepsis protocol completion rates to hospital reimbursement, says Amal Trivedi, senior author of the paper and a professor at Brown University’s School of Public Health and medical school.

“If our study findings extend beyond New York, it raises concerns about the possibility of these quality improvement initiatives for sepsis exacerbating racial disparities in care.”

Death rates

The study shows that hospitals that serve higher proportions of black patients had smaller improvements in protocol completion. Within the same hospital, white and black patients received similar care, in terms of protocol completion rates, Trivedi says.

Prior research found that minority-serving hospitals tend to have more financial stress, fewer resources, and less infrastructure to devote toward quality improvement measures, which is likely the reason why minority-serving hospitals had smaller improvements in sepsis protocol completion, Trivedi says. These hospitals also tend to treat more uninsured patients and those on Medicaid.

After adjusting for risks, such as type of infection, age, and other chronic health conditions, the team did not find a statistically significant change in hospital mortality rates between racial and ethnic groups, despite the disparities in care delivery.

During the first three months of the initiative, 25.8 percent of white sepsis patients and 25.4 percent of black sepsis patients died while in the hospital. Two years into the initiative, 21.3 percent of white sepsis patients and 23.1 percent of black sepsis patients died while in the hospital.

“Our work highlights the need for state and federal policy makers to anticipate and monitor the effects that quality improvement projects, such as the New York State Sepsis Initiative, have on racial and ethnic minority groups,” says first author Keith Corl, an assistant professor of medicine in the pulmonary, critical care, and sleep medicine division at Warren Alpert Medical School. “Racial and ethnic minority groups can get left behind. Knowing this, it is our job to better design and monitor these programs to ensure racial and ethnic minority patients realize the same benefits as white patients.”

In order to improve health equity, policymakers may need to devote additional funding to under-resourced hospitals that experience challenges in improving sepsis care so that their performances can match that of other hospitals, Trivedi says.

The New York State Department of Health’s Institutional Review Board approved the work. The Department of Veterans Affairs and the Warren Alpert Medical School funded the work.
