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.
