Top U.S. hospitals with the most operating rooms

Which U.S. hospitals have the most operating rooms?

The U.S. hospital with the most operating rooms is Cleveland Clinic Main Campus. This Ohio-based hospital is also a top U.S. hospital by net patient revenue (third place) and is a top teaching hospital by number of staffed beds (second place). With a higher capacity for patient care, as well as a high net patient revenue (NPR), Cleveland Clinic Main Campus sees more patients for surgical procedures, and is a top hospital by total annual surgeries.

The second top hospital by number of operating rooms is Houston Methodist Hospital. Like Cleveland Clinic Main Campus, Houston Methodist Hospital also makes the list of top teaching hospitals by number of staffed beds (seventh place). With a higher bed capacity, as well as the responsibility to provide teaching opportunities for a variety of procedures, this hospital requires a greater number of ORs.

Massachusetts General Hospital comes in third place in the list of top hospitals by ORs. Not only does this hospital have a large number of ORs, but it also comes in third place on the list of top hospitals with the highest operating room costs.

How does operating room capacity differ based on a hospital’s location?

In the U.S., hospitals’ operating room capacities may differ based on location relative to the area population. In particular, hospitals in large metropolitan areas with larger patient populations tend to have more ORs compared to hospitals in rural areas. Since most patients tend to seek surgical care in regions in which they reside, it is expected that areas with larger populations require greater facility capacity to accommodate more procedures.

For example, multiple hospitals in the list above, such as Houston Methodist Hospital and Memorial Hermann - Texas Medical Center in Houston, Thomas Jefferson University Hospital and Hospital of the University of Pennsylvania in Philadelphia, and The Mount Sinai Hospital and NewYork-Presbyterian Komansky Children’s Hospital in New York City, are in some of the largest cities in the country by population.

What are the different types of operating rooms?

The three main types of operating rooms are digital, hybrid, and integrated, and each OR type is designed to meet the differing needs of hospitals and the patient populations they serve.

Digital operating rooms are built around a central data system that integrates imaging, software, and video data systems. These ORs enable simpler sharing, transfer, and collection of medical data, which may be referenced during the operation or used afterward to assess outcomes and inform care plans.

Hybrid operating rooms bring together surgical equipment and medical imaging devices, which allows imaging to be done right in the OR. Hybrid ORs are equipped for most surgical disciplines but are generally best suited to those requiring high-resolution imaging of smaller body parts, such as cardiovascular or neurological surgery.

Integrated operating rooms contain integrated surgical systems that combine lighting, audio, video, and operating equipment in a single, centrally controlled unit. This integration improves surgical efficiency by eliminating the need to move equipment to and from the operating table during a procedure.
