Texas Health & Science University is closing the doors on its My Atria Health facility, ending its nearly 50-year career as the largest provider of primary care in the state.

The news was announced Monday by state health officials, who said they were removing My Atrial Health’s facilities in Dallas, Austin and Fort Worth.

“Our health system is not able to meet the growing demand for primary care at home and in nursing homes, so we are closing facilities and instituting a systemwide review to determine the best way to move forward,” said Dr. William Roper, Texas Health Commissioner.

“In the meantime, we will continue to offer primary care to patients who need it and to those who need our services.”

The move comes as state officials grapple with a new trend of Medicaid expansion that has made primary care more accessible to low-income patients.

About a third of Texans rely on Medicaid, which has helped many of them stay in their homes.

That trend is expected to grow as the U.S. economy strengthens.
