TriStar Health, a division of HCA Healthcare, has unveiled plans to invest more than $500m to expand capacity and add new services across its healthcare network.

The capital investment, which will be carried out over the next three years, will be made on new construction, expansion of campus projects and addition of new technology and services to existing healthcare facilities.

The investment is in addition to the $300m spent over the past three years.

TriStar Health president and CEO Heather Rohan said: “TriStar Health is committed to investing in high-quality, comprehensive healthcare services. These capital investments will help to further enhance patient care and position us to be able to meet and exceed the growing demand for healthcare services.”

TriStar Health will invest $123.7m on its four-floor expansion of Centennial’s Medical Center, and addition of a joint-replacement centre. The final phase of the project is expected to conclude in early 2019.

The health care organisation has allocated an additional $50m to renovate existing patient care floors throughout the 47-acre hospital campus. Nearly $69m will be spent to build an eight-level parking garage, which is slated to complete next year.

Additionally, the hospital operator will spend $69.3m at TriStar Skyline Medical Center to construct two additional floors to the existing hospital tower. The work, which is scheduled to commence in June this year, will expand emergency department and increase parking space.

Nearly $18.6m has been set aside for the patient tower expansion at TriStar Summit Medical Center. Scheduled to be completed in late 2019, the tower will include addition of an eighth floor medical/surgical bed unit.

Under the investment plan, the hospital operator will spend $12m to expand behavioural health and clinical decision units at TriStar StoneCrest Medical Center; $28.1m on behavioural health hospital in partnership with Maury Regional Medical Center in Columbia. Furthermore, the company will invest $10m on eight bed, free-standing emergency room in Mt. Juliet.
