Montgomery County business leaders have sent a joint letter to Maryland hospital regulators in support of Adventist HealthCare's hospital plan for Clarksburg, one of two proposals vying to build the county's next hospital. The decision to grant the hospital certificate of need is in the hands of the Maryland Health Care Commission. The commission has already received competing requests for approval from Adventist and Holy Cross Hospital, which aims to build a new hospital in Germantown, the Washington Business Journal reports.
