Surgery Suite Benchmarks

Determination of the space required for a surgery suite is typically established in the programming phase of design. A number of complex factors contribute to the space needs, including:

  1. The number and size of operating rooms,
  2. What pre- and post-surgery care will be provided in the Surgery Suite, such as patient screening, prep, Post Anesthesia Recovery (PACU), "Phase II" recovery and extended observation,
  3. The location of instrument reprocessing services and storage of clean, sterile instrument sets,
  4. Equipment and supply storage,
  5. Staff support, including locker, break and administrative areas.
Among factors that have increase the area per operating room over the past two decades are the shift to outpatient care; increase equipment associated with endovascular, cardiovascular, orthopedic, neurosurgery and other procedures; increased utilization of single patient rooms for prep and phase II recovery, and the integration of imaging and other services into an integrated platform.

The following table highlights two key measures of surgery suite space - the total departmental gross square feet per operating room, and the net square footage size of the Operating Room.

This table summaries key statistics on a group of new surgery suite projects. The table includes the number of operating rooms, the total departmental gross square feet of the service, the ratio of DGSF per O.R. and the average nsf per operating rooms, the smallest and the largest rooms.

Notes: The Homestead area included holding and recovery beds that are shared with the endoscopy suite. The net of the endoscopy suite was not included in the surgery area, but the additional holding capacity distorts the DGSF per O.R.
