Saint Thomas Health Services has sold off its ownership portion of five occupational health centers to Massachusetts-based Occupational Health + Rehabilitation Inc. (OHRI).

The clinics, located in Nashville and Murfreesboro, were acquired by the health system in its acquisition of Baptist. System CEO Tom Beeman had been working to renegotiate a better deal with the company, which managed the clinics under a 20-year contract.

“We’ve told OH+R that we need to either improve the relationship or sell [them] the other piece, but we can’t keep on the way we are now,” he told Nashville Post in a January magazine article.

OH+R operates 35 occupational health centers and provides work place health services.
