Top 10 hospitals by operating room square footage 

Why is operating room square footage important? 

Operating room (OR) square footage is the total number of square feet in a healthcare facility’s operating rooms. Like total facility area or the number of staffed beds, operating room square footage indicates a healthcare facility's size. A larger hospital operating room square footage suggests the facility has more space and resources to complete surgeries and other essential procedures.  

Here is a list of the top 10 hospitals in the U.S. with the most operating room square footage.

Operating room standard design 

Specialists design operating rooms to have devices and equipment, so that healthcare providers can optimally provide surgical care to patients.  

Operating room standards 

A study published by the Nature Public Health Emergency Collection determined that operating rooms must have a multitude of elements, including: 

  • Proper ventilation 
  • Washable and soothing walls  
  • Emergency drugs and supplies 
  • Adequate lighting 
  • Non-slippery flooring 
  • Appropriate doors and windows  
  • Specialized rooms for certain procedures 
  • Hard, impervious ceilings  
  • OR rooms of 6.5 m × 6.5 m × 3.5 m 

What are the three types of operating rooms? 

The three types of operating rooms are digital, hybrid and integrated.  

Digital ORs configure various imaging, software and video platforms, providing a depth of medical data within the space. Digital ORs also record, collect and transmit data to relevant IT systems for storing.  

Hybrid ORs accommodate a range of surgical areas, with a general focus on vascular and minimally invasive procedures. Hybrid ORs typically contain elements related to imaging, such as MRI and CT. These aspects let providers review medical imaging without having to move the patient.  

Integrated ORs connect a range of patient information, including video, audio, specialized equipment, building automation and surgical and room lights.
