The federal agency that controls more than $1 trillion in Medicare and Medicaid funding has moved to prevent nursing homes from forcing claims of elder abuse, sexual harassment and even wrongful death into the private system of justice known as arbitration, the New York Times reported today. An agency within the Health and Human Services Department yesterday issued a rule that bars any nursing home that receives federal funding from requiring that its residents resolve any disputes in arbitration, instead of court. The rule, which would affect nursing homes with 1.5 million residents, promises to deliver major new protections. The new rule on arbitration came after officials in 16 states and the District of Columbia urged the government to cut off funding to nursing homes that use the clauses, arguing that arbitration kept patterns of wrongdoing hidden from prospective residents and their families.
