2018 FGI Guidelines – What you need to know

Following the recent publication of the new 2018 edition of the Facility Guidelines Institute’s Guidelines for Design and Construction of Hospitals, we asked Tobias Gilk, Consultant to Metrasens, to provide an overview of the key changes you need to be aware of.

One of the things that makes healthcare so complex is that it isn’t just one thing. You can have a brilliant surgeon or the most talented nurse, but without an operating room, the outcomes of those talents are, at best, compromised. Because hospitals and imaging centers depend on a balance of human capital (skilled people), organization (decision-making structures), and physical resources (building and equipment), there are quality standards that govern the minimum acceptable criteria for each.

When it comes to healthcare or hospital design standards, the most frequently-used minimum standard in the US is the Facilities Guidelines Institute (FGI) Guidelines for Design & Construction of Hospitals. While not a building code, per se, the FGI guidelines describe the objective planning criteria for healthcare facilities… from patient rooms, to ORs, to imaging and MRI suites. Updated on a four-year cycle, versions of the FGI criteria have been adopted by most US states as their minimum state standards for new hospitals and healthcare construction. The 2018 edition of the FGI guidelines offer some particular new benefits to radiology safety, in general, and MRI safety, in particular.

What’s changed in the 2018 FGI Guidelines for Design & Construction of Hospitals?

Within radiology, in general, the most substantive change in the 2018 FGI guidelines is the development of an imaging acuity/intervention classification system. In short, depending on the imaging patient’s acuity (and need for clinical support), the amount of intervention (e.g. image-guided biopsies or procedures), and the use of sedation, the planning and design criteria for the room change. This puts the first focus on the patient, before the piece of imaging equipment. This new criteria requires that we identify what the patient needs prior to identifying what the imaging equipment needs.

While it’s an imperfect description, we can think of ‘Class 1’ imaging facilities as being classic ‘outpatient imaging’ where the most invasive thing a provider might do would be to inject a contrast agent. ‘Class 2’ imaging facilities can be thought of as platforms for intervention. If we’re doing image-guided biopsies or minimally-invasive procedures with imaging assistance, the spaces should have the additional infrastructure for medical gases, emergency power, and infection control. ‘Class 3’ imaging facilities are surgical environments, and may have been thought of as “hybrid ORs” or “intraoperative imaging.”

Changes to MRI design guidelines

In addition to the application of the patient-centric three-class system, MRI design criteria have some upgrades in the 2018 FGI guidelines over the 2014 (and earlier) editions. In the 2018 edition, MRI physical safety is improved with:

  • Explicit references to both the ACR Guidance Document for MR Safe Practices and the IEC standard for the safety of MRI equipment.
  • Requirements for patient screening spaces (clinical and physical screening).
  • Requirement for ferromagnetic (only) detection and warning systems.
  • Access restrictions for the 5 gauss line.
  • And cryogen-specific safety protections.

In addition, mobile MRI units – which previously were omitted from the physical safety requirements – are no longer exempted. This means that, barring a specific waiver, the use of trailer-based MRI units needs to provide (either in the trailer or in the adjacent building) four-zone access and screening, access controls, 5 gauss restrictions, and ferromagnetic detection.

Create safer environments by moving to the new criteria now

While individual states update their minimum criteria for hospital buildings in their own time (there are, astonishingly, states that are still using radiology/hospital minimum criteria from over 15 years ago), I would like to ask that all architects, engineers, equipment planners, and hospital facility managers move to the 2018 FGI guideline criteria now – even if your state will take months or years to get there – at least for your imaging services.

The operational and safety benefits of the changes in the 2018 edition will help us all make radiology and MRI facilities that are both safer and better suited to the specific demands of buildings serving modern imaging today, and into the future.

With multiple professional and accrediting bodies involved, it can be difficult to keep track of what the various published safety recommendations and guidelines in the US say. Metrasens is pleased to assist by providing this summary of the present status as it relates to the growing adoption of ferromagnetic detection systems (FMDS) for the prevention of MRI projectile incidents.
