SPACE PLANNING: How to determine number of ORs needed

Tips for the planning process for a new surgical suite are given in this brief newsletter article by an experienced health care architect.  There are some interesting facts that are otherwise difficult to find in the literature:

  • What is the difference between an operating room and a procedure room?
  • What is a hybrid operating room?
  • How are some of the metrics used defined – room time, room turnaround time, throughput?
  • What is a target room turnaround time? (“…usually 15 to 20 minutes”)
  • How many hours are procedure rooms open? (“Most procedure rooms are available eight hours per day for a total of 480 minutes per day”)

Scheduling efficiency: A scheduling efficiency factor is multiplied by the annual minutes available per procedure room to account for periods of time that a case cannot be scheduled.  This factor may range from 70 percent for ORs or procedure rooms used for complex (and sometimes unscheduled) procedures — such as cardiothoracic, neurosurgery, and trauma/orthopedics — to 90 percent for an outpatient suite where all procedures are scheduled.”  (page 3)

Reduce air changes overnight in OR and save energy costs

This article describes changes in operating room design guidelines based on the new edition of the Facilities Guidelines Institute (FGI) 2014 Guidelines for Design and Construction of Hospitals and Outpatient Facilities.  In this blog post, I’m highlighting just one factoid — mentioned by the Chair of the Revision Committee that prepared these new guidelines.  He mentions that SETBACKs are now allowed in the operation of the surgical suite.  This means that the number of AIR CHANGES can be reduced at times when the operating room is not in use — such as overnight.

I like it that the expert quantifies the potential savings — “You can set back the number of air changes per hour, maintain temperature and humidity, and save $10,000 to $15,000 per year per operating room in energy costs.”  He notes that there may be upfront costs in order to install the appropriate dampers or controls, but that the facility would recoup these installation costs quickly.

Minimum space required for inpatient ORs is 400 square feet

This article is based on the new 2014 edition of the FGI Guidelines for Design and Construction of Hospitals and Outpatient Facilities.  There is a lot of great information included in this article, such as:

  • DEFINITIONS of invasive procedure, procedure room, operating room, hybrid operating room, restricted area, semi-restricted area, patient care station, bay, and cubicle.
  • MINIMUM EQUIPMENT needed for a surgical procedure (such as “an anesthesia machine,” or “two trash containers”)
  • REQUIRED PERSONNEL needed for a surgical procedure
  • RATIO of PACUs needed, which is 1.5 post anesthesia care unit (PACU Phase I) stations per operating room
  • MINIMUM space requirements for outpatient OR (250 sf)
  • MINIMUM space requirements for inpatient OR (400 sf)
  • MINIMUM clear floor area for procedure room (150 sf)
  • Formula for calculated needed number of hand-washing stations in preop and recovery = one for every four patient care stations
