After announcing this month it would sell its Dallas hospital, Houston-based University General Health System said Monday it is closing the facility. In an email, company president Don Sapaugh said patients no longer were being treated at University General Health - Dallas. He didn't say why or when officials began closing the 111-bed, acute care hospital the company bought two years ago. The closure is not expected to affect the company's flagship Houston facility, Houston University General Hospital, Sapaugh said. "We had begun discharging patients about a month ago and had very limited inpatient admissions over the last two weeks," he said. "At the time of closing, there were no patients in the hospital."
