The chief of Augusta's new MaineGeneral Medical Center hospital says demand for services at the facility has been huge. A month after the 192-bed hospital opened, officials say the medical/surgical and critical care units are full at least one day a week and some patients have to remain in the emergency department until beds become available. Chuck Hays, chief executive officer of the hospital's parent organization, tells the Kennebec Journal he is surprised by demand and officials are busy refining the processes to handle it.
