Which Texas health system has the most hospitals?

Tenet Healthcare, located in Dallas, ranks number one on our list with 82 member hospitals in its network. Next is Baylor Scott & White Health, with 50 hospitals. And Steward Health Care System takes third, with 40 member hospitals.

Notably, six of the top IDNs in Texas are in Dallas. This makes sense, because Dallas is the third most populous city in the state, behind Houston and San Antonio, which are also home to many of the top-performing health systems in Texas.

The top 25 health systems have 507 hospitals throughout Texas, with an average of 20 hospitals per health system.

What is a health system?

A health system is a healthcare organization that owns and manages a network of healthcare facilities. Most health systems consist of both inpatient and outpatient facilities, helping them provide a wide variety of comprehensive medical care.

What is an IDN?

An integrated delivery network (IDN) is another term for a health system.

What makes up the “number of hospitals” metric?

In the Definitive Healthcare platform, the “number of hospitals” metric calculates the total hospitals an IDN has under its organization. This metric can help indicate the size of an IDN. Though, it’s worth noting that the number of member hospitals alone does not determine the size of an IDN since health systems are also comprised of ASCs, imaging centers, physician groups, and more.
