Top 10 hospitals and IDNs by total facility area

There are roughly 6,000 hospitals and 1,000 IDNs in the U.S., both integral components of the U.S. healthcare industry. We’ve compiled a list of the top hospitals and integrated delivery networks (IDNs) by total facility area with our data. 

What is the total facility area? 

Total facility area is a measurement of the size of a healthcare facility. The number of beds often measures healthcare facility size. In contrast, total facility area indicates the number of square feet in an organization’s fixtures and facilities. 

Knowing the total facility area is beneficial because it gives insight into healthcare organizations’ costs, operations and governance. Healthcare organizations can learn how to use space better by understanding these factors. In turn, optimal space utilization inspires organizational advancement. Additionally, companies can discover new targets for products and services by having insight into which facilities may have the space and need.

What is the difference between hospitals and IDNs? 

A hospital is a single institution that offers medical care. Comparatively, an IDN, or health system, is an entity that owns and operates a network of healthcare facilities, like hospitals, ambulatory surgery centers and physician groups. Because IDNs typically encompass a large number of facilities, there are many healthcare providers within an IDN. IDNs also have greater market influence.  

Definitive Healthcare has data on more than 9,100 distinct hospitals and IDNs. 

Which hospital and IDN are the largest? 

The average facility square footage for hospitals was 7,890,101 square feet, while the average facility square footage for IDNs was 37,154,092 square feet. Of hospitals, Creedmoor Psychiatric Center in New York is the largest at 9,399,914 square feet. Of IDNs, HCA Healthcare in Tennessee is the largest at 72,580,337 square feet.  

As shown in the data above, healthcare organizations in New York appear three times across both lists and take the top two spaces on the hospital list, which makes sense since it is the fourth largest state in the U.S. Additionally, Tennessee appears four times across both lists. Nashville being a healthcare hub may help explain this since Vanderbilt University Medical Center, HCA Healthcare, Community Health Systems and LifePoint Health are all located in the greater Nashville area. 

Healthcare providers can apply this intelligence in adjusting space utilization strategies to achieve key performance indicators (KPIs) and learn more about potential clients and client needs.
