ORs of Tomorrow Can Yield Pay-offs Today

The operating room (OR) of the future is closer than many facilities think. While the level of sophistication in equipment and technology depends upon a facility’s budget and ability to retrofit to accommodate exciting new developments in OR modalities, facilities should be aware of the changing dynamics of OR design and planning.

The challenges of efficient and effective surgical planning are numerous, according to Charles Martin, AIA, and Lynne Shira, RN, BSN, both principals with the Seattle architecture firm NBBJ, who were part of the Designing High-Performance ORs, a day-long symposium presented by STERIS Corporation last October. Martin and Shira explain that owners/operators of medical facilities must find a way to juggle their increasing equipment needs, technology demands and compatibility issues. They see an upward trend among healthcare facilities in the overall demand for additional space to grow their surgical service lines, including new ORs, procedure rooms and the requisite spaces needed to support these new rooms. Today’s facilities require much greater flexibility in the infrastructure and its operational capacity to accommodate more integrated systems both in and out of the OR. Not only can this flexibility create an environment to better foster staff recruitment and retention, Martin and Shira say, but it can improve the patient experience.

The size of ORs has been increasing over time, with the OR of yesterday being about 400 to 500 square feet, with a total department space of about 2,000 square feet. The OR of today and tomorrow is now an average of 600 to 800 square feet, with a total departmental space between 3,200 and 4,500 square feet. The reason for this expansion can differ greatly from facility to facility, but many institutions are creating hybrid ORs that encompass and integrate surgical and interventional services, imaging and clinical services. This kind of OR can accommodate multiple care-delivery models and new technologies, as well as support clinical and administrative uses.

Fred Bentley, practice manager for syndicated research at the Advisory Board Co., says that ORs have been invaded by numerous “space-eating” technologies, such as PACS, C-arms, endoscopic towers, robotics and inter-operative MRIs. The space around the operating table has become increasingly cramped; an OR of 300 cubic feet frequently must accommodate about 115 cubic feet of surgical and anesthesia personnel and about 150 cubic feet of equipment, leaving just about 35 cubic feet of free space. It can be a struggle for facilities to balance comfort and efficiency, Bentley adds, that an OR of less than 400 square feet is now considered to be an anachronism because of its cramped, inflexible space; the 500-square-foot OR is now a tight fit; and an OR with more than 800 square feet is probably an over-indulgence and has the potential for too much dead space. The sweet spot, Bentley says, is an OR of about 600 to 650 square feet, which has enough space to accommodate equipment, but facilitates enough unimpeded circulation throughout the room. To cope with smaller ORs that cannot be immediately retrofitted, some facilities are opting to move some bulkier pieces of equipment out of the OR, such as a mobile C-arm that can stored in a corridor alcove or an adjacent equipment closet, or using utility booms to get equipment lifted off of the floor. Other facilities are opting for more streamlined integrated interventional suites that come turn-key from manufacturers such as STERIS.

A hybrid OR is quickly becoming a favorite option for some facilities wishing to make better use of their OR space. Neurological surgeon Jeffrey Yablon, MD, of the Lake Norman Regional Medical Center in Mooresville, N.C., defines a hybrid OR as “an actual operating room located within the surgical suite that accommodates uncompromised interventional, open and minimally invasive surgery within a given specialty.” Yablon says that a number of trends are driving the hybrid OR craze, especially recent technological advancements and specialists’ desire to expand their sphere of expertise amidst competing services. Another driver is the limited space with which many facilities must contend; Yablon says a hybrid OR can be used for several services or procedures and will provide maximum utilization of space. Yablon also cites increased competition for procedural services, with cardiothoracic moving into interventional cardiology, interventional radiology moving into vascular surgery and interventional cardiology moving into interventional radiology. Another factor is tighter reimbursement; Yablon says a hybrid OR’s flexibility will allow for this space to be fully used with a continual stream of reimbursement dollars. He adds that increased readiness and flexibility results in fewer complications and better outcomes, which ultimately achieves lower costs and higher profit margins.

Hybrid ORs are a win-win situation for surgeons, Yablon says, because they allow for improved patient care because of integrated technologies, and because they provide room flexibility and improved workflow. Nursing staff members like these ORs because they improve staff productivity, workflow and ergonomics, as well as improve room utilization and reduce scheduling challenges. And administrators like them because they help to retain surgeons and nurses as well as optimize capital monies. Yablon adds that hybrid ORs are not without their challenges – including costs, simultaneous competition for the room’s unique resources among surgeons and the need for continual future upgrades – but says the advantages frequently outweigh the challenges.

One healthcare system that has moved boldly into the OR of the future by embracing cutting-edge technology is the Carondelet Health Network in Tucson, Ariz., whose hybrid ORs boast the BrainSUITE iCT, a dual-room intraoperative large-bore, multi-slice CT with sliding-gantry from BrainLAB. Neurosurgeon Eric Sipos, MD, FACS, medical director of the Carondelet Neurological Institute, says the advantages of a two-room CT scanner system include the minimized disruption of the familiar surgical workflow with a maximized CT scanning range providing the widest range of patient positioning. The surgical table position for scanning can be stored prior to draping to avoid collisions with scanner, and once positioned for surgery, the patient is not moved, especially outside of the sterile air field; the anesthesia is fixed and constant throughout the surgical and imaging procedures. With a sliding gantry moving between two ORs, there might be the opportunity for cross-contamination, but Sipos emphasizes that the preservation of the sterile environment is achieved and the patient in the adjacent OR is not compromised in any way. Carl Colombi, technical consultant with the Integrated OR Solutions (iORS) Division of BrainLAB, says the BrainSUITE fully integrated intraoperative CT surgical operating room can facilitate surgical planning and navigation, as well as achieve data management and coordinated equipment integration.

While this level of technology might be reserved for the larger health systems, ASCs shouldn’t count themselves out of the technology game nor assume they cannot replicate a hybrid OR set-up. “Over the years, we have seen more and more surgical cases migrate to the outpatient environment, primarily due to the advances in anesthetic agents and minimally invasive technologies,” Shira says. “Our previous thinking that an outpatient surgery is for ‘minor’ surgical procedures simply doesn’t hold true any longer. The equipment and technology required for minimally invasive work demands a surgical footprint and boom configurations that are not unlike the inpatient environment. ASCs that want to plan for this technology in the future need to remember this as they are planning.” Shira continues, “Recognizing that ASCs are held to a different building standard than hospitals, there should still be planning for proper air exchanges, good surgical traffic patterns with non-restricted, semi-restricted and restricted zones understood with the design. And of course, there can be no compromise on safety protocols and cleaning protocols regardless of the location of the surgical environment.”

Martin and Shira emphasize that the numerous rapid advances in imaging technology are dictating some OR planning and design elements, and note that many imaging interventions are transitioning from diagnostic to therapeutic, thus blurring the boundaries between imaging and surgery. The goal of many facilities is to integrate these departments into a single service with common support in terms of supplies, equipment and staff. If designed correctly, this concept also can eliminate the all-too-common duplication of pre- and post-operative functions, as well as eliminate the duplication of space, equipment and supply storage. Martin and Shira add that integration of staff with similar skill sets can greatly improve operational efficiencies. The integration concept also can apply to universal procedure rooms that specialists can share, as well as universal prep and recovery areas that can accommodate varying patient volumes throughout the day, as well as minimize patient transfers and reduce the number of supply-distribution points.

While we have seen how the physicality of the OR is evolving for the future, it’s important to note that healthcare professionals are following suit. Bentley points to the trend of surgeons and interventionalists becoming one and the same in the future; in the past, these two groups have performed distinct classes of procedures, while in the present, some surgeons are learning select interventional techniques. In the OR of the future, it may be no surprise to see surgeons familiar with nearly all major interventional procedures and perform them frequently; there may also be the rise of the multi-purpose proceduralist. Bentley says these proceduralists can be co-located on the same floor of a facility, or they can even be housed in the same suite, functioning in what Bentley calls a “multi-purpose sandbox” to accommodate all kinds of disciplines.

No next-generation OR can be planned and executed without buy-in from all stakeholders during the project planning and management process, including surgeons and clinical personnel, administration, the architect, the engineer, the IT department and key vendors, according to collaborators Chris Kantorak, technical consulting manager with BrainLAB, Inc., Brian Hartman, project design manager with STERIS Corporation, and Paul Niehaus, project manager with Philips Healthcare. They say that advanced OR suites require space for technology, personnel and ancillary equipment, and that design input from all user groups must be obtained to ensure an optimal environment for all. More specifically in terms of roles among stakeholders, the architect is responsible for evaluating trends such as fixed-based imaging versus mobile imaging, and OR integration; providing for the expansion to a larger OR footprint ; and understanding the changes in sterility needs when going from an imaging suite to a flexible hybrid OR suite, for example. They must also design into the OR future flexibility, such as empty conduits for information/video routing, blank structural plates and positions to accommodate new equipment in the future. To this end, the equipment manufacturer can help plan for the support of new technologies as they are added. In turn, the vendor plays a key role by helping to maximize functionality and the placement of multiple technologies, offering design expertise with proper sequencing of design needs, and planning for both existing and future technologies or evolving clinical procedures.
