Albany Medical Center will pay $4.5 million to settle its share of a federal class-action lawsuit alleging officials conspired with counterparts at other hospitals in the area to keep pay down for about 4,000 registered nurses.

Court documents say similar settlements for about 2 percent of nurses' pay from June 2002 to June 2006 were reached with companies operating St. Peter's Hospital in Albany, St. Mary's Hospital and Samaritan Hospital in Troy and Albany Memorial Hospital.

The hospital companies admit no wrongdoing. The suit is still pending against Ellis Hospital in Schenectady.

A call to Albany Med was not immediately returned Wednesday.

Attorney Daniel Small, representing the nurses, says about $9 million altogether is in an escrow account pending the end of the case. Lawyers are requesting one-third.
