AORN’s Guideline for Design and Maintenance of the Surgical Suite provides useful advice for projects large and small.

When upgrading or renovating your surgery center, design of your perioperative space is obviously a top priority. AORN’s new Guideline for Design and Maintenance of the Surgical Suite is intended to help you get started on that vital task.
AORN says the new evidence-based guidelines help teams who are updating ASCs explore and address key components of these projects. The idea is to better enable ASC leaders to engage in advanced planning, cost-conscious design and sustainable maintenance strategies using evidence-based guidance and tools.
Here are five helpful highlights from the guidelines:
Work together. The guidelines emphasize that a perioperative nurse should be included in renovation projects to bridge the gap between non-clinical and perioperative staff. One important scenario for clinical input is to “facilitate a safe, efficient and low infection risk working environment when construction occurs adjacent to functioning patient care areas,” says AORN Senior Perioperative Practice Specialist Mary Alice Miner, PhD, RN, CNOR.
Know your space requirements. ASCs must recognize the differences between function and requirements. For example, the minimum space requirements for an outpatient OR can be smaller than for an inpatient OR. However, Dr. Miner notes, space requirements for hybrid OR equipment and sterile processing areas in outpatient environments should be the same as for inpatient spaces.
Dial in efficiency and costs. The guidelines can assist ASC design teams in devising a layout that maximizes efficiency while also keeping costs in check. For example, one study cited in the guidelines examined two different layouts for a facility’s surgical suite: a “center-stage” layout with all patient rooms centered around one staff workroom and patient entrances, and an “onstage-offstage” layout where patient and staff entrances lead into separate corridors. “Both had positive and negatives, but the authors concluded that creating functional zones was necessary to stimulate workflow and teamwork as well as patient-centeredness,” says Dr. Miner.
Understand and address air quality. Perioperative nurses should be familiar with, and help planners address, issues relevant to air quality and movement in the OR, including HVAC system design and function; the number of air changes a system is set to execute; humidity range parameters; temperature and humidity levels in the OR when procedures are being performed in the room; and airflow direction in the OR.
Build sustainably. Managing energy usage not only can protect the environment but also lead to significant cost savings. The guidelines say a ventilation setback strategy during the planning phase that is incorporated into the HVAC system could slash energy costs by reducing the number of air exchanges during periods when an OR is unoccupied, says Dr. Miner.
