LOS ANGELES — The husband of a Black woman who died hours after childbirth in 2016 sued Cedars-Sinai Medical Center on Wednesday, saying she bled to death because of a culture of racism at the renowned Los Angeles hospital.

Charles Johnson IV said he discovered the disparity in care women of color receive at Cedars compared to white women during depositions in his wrongful death lawsuit that is scheduled to go to trial next week in Los Angeles Superior Court.

“There’s no doubt in my mind that my wife would be here today and be here Sunday celebrating Mother’s Day with her boys if she was a Caucasian woman,” Johnson said at a news conference outside the hospital. “The reality is that on April 12, 2016, when we walked into Cedars-Sinai hospital for what we expected to be the happiest day of our lives, the greatest risk factor that Kira Dixon Johnson faced was racism.”

Johnson died about 12 hours after having a scheduled cesarean section that was performed in 17 minutes to deliver the couple’s second son, Langston.

“This is sloppy. It was butchery,” attorney Nicholas Rowley said. “It shocked everybody that we deposed, all the health care providers, even the head of (obstetrics) here, the head of labor and delivery, looked at it and said ‘No, I’ve never seen one done that fast.”’

Despite signs she was bleeding internally and over the desperate pleas of her husband, Kira Johnson languished for hours without being readmitted to the operating room until it was too late, the civil rights lawsuit said. At one point, a nurse told Charles Johnson that his wife wasn’t a priority, according to the lawsuit. She died from internal bleeding — nearly 90% of her blood was later found in her stomach, Rowley said. Her bladder had been lacerated and she hadn’t been sutured properly.

The hospital, which has fought the malpractice lawsuit, said in a statement that it was founded on principles of diversity and health care for all and it rejected “any mischaracterization of our culture and values.”

“We are actively working to eradicate unconscious bias in health care and advance equity in health care more broadly,” the statement said. “We commend Mr. Johnson for the attention he has brought to the important issue of racial disparities in maternal outcomes.”
