A shelf full of outdated facility master plans is a common sight in the facility manager’s office of a large medical center. These are often very thick documents with beautiful graphics that explain in great detail the phased stages of a multi-year building project. There are many reasons why these plans may not have been implemented but the planning process itself is a major factor.
Imaging and procedure rooms fall into several size categories — small procedure room, typical imaging room, or larger specialty imaging room. Diagnostic equipment has generally become more compact over the last decade. For example, equipment used for chest X-rays, mammography, ultrasound, and pulmonary and neurodiagnostic testing is compact and commonly mobile, requiring only a small procedure room. Most general radiographic and fluoroscopic equipment can be accommodated in a typical imaging room. Computed tomography (CT) units are also becoming more compact but require a contiguous control room. Magnetic resonance imaging (MRI) and interventional procedure suites require a larger footprint that includes the procedure room, control room, and adjacent space for equipment components. Imaging equipment may also require lead shielding, enhanced floor loading capacity, and other unique design features.
Planning a surgery suite used to be fairly simple. General operating rooms were used for a wide range of procedures with dedicated operating rooms limited to cardiac surgery and orthopedics. Today, the question “How many operating rooms are needed?” is complicated by more stringent distinctions between operating rooms and procedure rooms, changing technology and increasing specialization, and the convergence of diagnostic imaging and surgical procedures. From a facility planning perspective, the number, size, and specialization of the operating rooms (ORs) is the single biggest factor contributing to the overall footprint of the surgery suite (and project cost). Moreover, the numbers and sizes of related patient care and support spaces are planned based on the number and types of ORs. And, from an operational standpoint, the number of ORs drives ongoing staffing and related operational costs.
Sometimes a preliminary space estimate is needed to evaluate location alternatives, conduct a feasibility study, or develop a preliminary cost estimate for construction or renovation. Once the number of procedure rooms is determined, an estimate of the total footprint required for the diagnostic imaging suite can be made using the range of DGSF (DGSM) per procedure room shown in this post.
When it comes to parking, hospitals seem to never have enough. At the same time, customers ― whether patients, staff, or visitors ― always want to park as close as possible to the their designated entrance. Because easy and convenient access is a prime indicator of hospital customer satisfaction, U.S. hospitals are rethinking the expansive asphalt parking lot and dreary concrete parking structure. Innovations in design, technology, and financing, along with careful planning, can mitigate shortages and improve customer convenience. Now with a global pandemic, parking lots and structures are also being called into action as part of an organization’s emergency response strategy.
The hospital surgery suite has undergone revolutionary change over the past several decades. For a long time, the focus has been on shifting surgery to a lower-cost outpatient setting. This has been replaced with a focus on lowering both the costs and risks of surgery with the ongoing migration from invasive to less-invasive surgery or noninvasive procedures. Minimally-invasive, image-guided, robotic, and telesurgery ― along with intraoperative imaging techniques ― continue to replace traditional surgical procedures. Aside from the economies of scale achieved with larger surgical suites, the biggest single factor contributing to the overall footprint of the surgery suite is the size and specialization of the individual operating rooms (ORs). Other factors include the proportion of outpatient surgery performed in the suite, and the type of patient care spaces provided, as well as the efficiency of the surgical suite layout.
