Physician-owned hospitals in Texas will infuse $2.3 billion into the state's economy this year, the largest projected economic impact by such hospitals in the nation, according to a study. Texas physician hospitals also will pay close to $86 million in property, payroll and income taxes this year, according to Health Economics Consulting Group, the Morristown, NJ-based health policy research firm behind the study. Many of the state's largest nonprofit hospital systems have partnered with physicians to create joint venture models in which the nonprofit and physicians share ownership.
