Cerner Corp. and a small Kansas hospital have become embroiled in a dispute over failed attempts to install an electronic medical records system. Girard Medical Center, a critical-access hospital northwest of Pittsburg, Kan., had sued the North Kansas City-based supplier of information technology to hospitals, doctors and others in healthcare. Their quarrel is now in arbitration under an order issued in U.S. District Court in Kansas City, Kan. The hospital said Cerner also failed to deliver the system in time to qualify Girard for federal incentive payments it needed to make the $2.9 million project affordable.
