Understanding Space Classifications in Ambulatory Surgery Centers (ASC): Unrestricted, Semi-Restricted, and Restricted Areas
Introduction:
Ambulatory Surgery Centers (ASCs) feature three primary space classifications: Unrestricted, Semi-Restricted, and Restricted. These classifications, essential for maintaining cleanliness and procedural integrity, are guided by the FGI (Facilities Guidelines Institute) Guidelines for Design and Construction of Health Care Facilities.
The Importance of Space Design in ASCs:
Designing an ASC requires careful consideration of space flow and relationships. Establishing clear demarcations between Unrestricted, Semi-Restricted, and Restricted areas is crucial for ensuring hygienic conditions, patient safety, and effective infection control practices in ASCs.
Unrestricted Space in ASCs:
Unrestricted space in an ASC is accessible to patients and visitors. These areas don’t require special ventilation or air filtration as they are not used for surgical procedures. Common examples include:
Waiting rooms
Consultation and examination rooms
Administrative offices
Staff breakrooms and locker rooms
Semi-Restricted Spaces in ASCs:
Semi-Restricted spaces in ASCs, where medical staff and patients interact, demand enhanced environmental controls like air filtration and temperature management. PPE usage is mandatory here to prevent infection spread. Access is monitored by staff, often through nurse stations or, less commonly, cameras. These areas are typically demarcated by a “red line,” and include:
Corridors leading to operating rooms
Decontamination and sterilization areas
Clean and sterile storage areas
Restricted Space in ASCs:
Restricted spaces in ASCs are where surgical procedures occur, necessitating the highest level of environmental control. Advanced air filtration and pressure differentials are crucial to inhibit infection spread. Staff and patients must wear PPE, and entry is allowed only through Semi-Restricted areas. Examples include:
Operating rooms
Certain procedure rooms
Certain imaging rooms
