Two Alabama nursing facilities are being investigated by the Occupational Safety and Health Administration following the deaths of four nurses due to COVID-19. 

The federal agency is investigating both the Crowne Health Care of Mobile, a 148-bed and four-star rated facility in Mobile, AL, and the Marion Regional Nursing Home, a 79-bed and four-star rated facility located in Hamilton, AL, according to a report by AL.com.

A spokeswoman for Crowne Health Care told McKnight’s the company is “aware of the matter and they’re cooperating.” A message left by McKnight’s with Marion Regional was not returned by production deadline. 

One staff member at Marion Regional has died from COVID-19, while there have been a total of 23 staff members to contract the disease, according to the latest data from the Centers for Medicare & Medicaid Services. 

Family members of a nurse who died accused Marion Region supervisors of disregarding the worker’s symptoms and making her work a week before her death, AL.com reported. Relatives also alleged the facility didn’t require workers to wear masks after the first resident tested positive for the disease. 

An April outbreak at Crowne Health Care happened resulted in the deaths of 22 residents and three workers, according to a previous statement from the company.

Alabama currently does not require nursing homes to test all of its residents and staff members for COVID-19, according to the report. OSHA has also called for nursing homes to conduct regular screening, supply personal protective equipment and quarantine exposed workers.
