An Alabama hospital system says it’s going ahead with planned surgeries despite a computer hack that is affecting digital systems.

DCH Health Systems posted a note Tuesday night saying elective procedures and surgical cases scheduled for Wednesday will go ahead as planned.

A statement says backup procedures will allow workers to provide safe and effective care.

The company has temporarily stopped accepting new patients at its hospitals in Tuscaloosa, Northport and Fayette because of a ransomware attack that began affecting computers early Tuesday. New patients are being sent to Birmingham hospitals or elsewhere.

A spokesman says the attack is making it impossible for some computer programs to communicate with each other, but no patient data is believed to be lost.

The three hospitals have about 850 beds total.
