A federal jury in Colorado has returned a combined $383.5 million jury verdict in favor of the families of three patients who died of heart attacks after receiving dialysis treatments from Denver-based dialysis provider DaVita Inc.

Jurors in the U.S. District Court for the District of Colorado on Wednesday ordered DaVita to pay $125 million in punitive damages each to the estates of Irma Menchaca, Gary Gene Saldana and Deborah Hardin, which accused the company of negligence and fraudulent concealment in administering the name-brand GranuFlo dialysis solution at its clinics, despite warnings that it could cause serious injury or death.
