Black people most likely to be restrained in EDs

SAN FRANCISCO – Although less likely than Whites to get a psychiatric diagnosis, Blacks were more likely to be physically restrained at three North Carolina emergency departments – especially when they were brought in by police, a new study finds.

In contrast, Hispanic/Latino patients were less likely to be restrained than both Blacks and Whites, researchers reported in a poster presented at the annual meeting of the American Psychiatric Association. The study authors also found that clinicians rarely turned to restraints, using them in just 2,712 of 882,390 ED visits (0.3%) over a 7-year period.

The study doesn’t examine why the disparities exist. But lead author Erika Chang-Sing, a medical student at Yale University, New Haven, Conn., said in an interview that it’s clear that racial bias is the cause of the differences in restraint rates among Whites, Blacks, and Hispanics/Latinos. “We think that there are multiple contributing factors to the higher rates of restraint for Black patients brought to the hospital by police, and all of them are rooted in systemic racism,” she said, adding that “the lower odds of restraint in the Hispanic or Latino group are also rooted in systemic racism and inequity.”

According to Ms. Chang-Sing, researchers launched the study to gain insight into the use of the restraints in the Southeast and to see what’s happening in light of the recent publicizing of killings of Black people by police. Being taken to the hospital by police “might contribute both to the individual patient’s behavior and the health care provider’s assessment of risk in determining whether or not to apply restraints,” she said.

Other research has linked ethnicity to higher rates of restraint use. For example, a 2021 study cases of patients under mandatory psychiatric hold in 11 Massachusetts emergency rooms found that Blacks (adjusted odds ratio, 1.22) and Hispanics (aOR, 1.45) were more likely to be restrained than Whites.

For the new study, researchers retrospectively tracked 885,102 emergency room visits at three North Carolina emergency departments from 2015 to 2022, including 9,130 who were brought in by police and 2,712 who were physically restrained because of the perceived risk of violence. “Providers use restraints, or straps, to secure the patient’s wrists and ankles to the bed,” Ms. Chang-Sing said.

Blacks made up 52.5% of all patients, but 66% of those who were restrained. The numbers for Whites were 35.7% and 23.9%, respectively, and 5.7% and 3.2% for Hispanics/Latinos. Black patients were less likely than Whites to get a psychiatric primary emergency department diagnosis (aOR, 0.67), but those in that category were more likely than their White counterparts to be restrained (aOR, 1.36).

The higher risk of restraint use in Blacks overall disappeared when researchers adjusted their statistics to account for the effects of sex, age, and type of insurance (aOR, 0.86). Ms. Chang-Sing said the study team is reanalyzing the data since they think insurance may not be a confounder.

Why might Hispanic/Latino ethnicity be protective against restraint use? “This may be due to language barriers, fear of law enforcement, and avoidance of the hospital in the first place,” Ms. Chang-Sing said.

Emergency physician Wendy Macias-Konstantopoulos, MD, MPH, MBA, of Harvard Medical School and Massachusetts General Hospital, both in Boston, coauthored the 2021 study on police restraints. In an interview, she said the new findings add to previous research by providing data about the role played by the police who bring patients to the ED. She added that there is no evidence that certain populations simply need more restraints.

What can be done to reduce disparities in restraint use? Mental health teams can make a difference by responding to mental health emergencies, Ms. Chang-Sing said. “These providers can be instrumental in communicating to patients that the intention is to care for them, not to punish them.”

Another strategy is to increase the number of clinics and crisis response centers, she said. Hospital-based crisis response teams can also be helpful, she said. “Because these teams are focused only on behavioral emergencies, they can be more thoughtful in avoiding the use of restraints.”

No study funding was reported. The study authors and Dr. Macias-Konstantopoulos have no disclosures.
