What is ICRA and Why Does It Matter for Hospital Renovations?

When a hospital needs new flooring in a patient wing, or a clinic decides to expand its emergency department, the construction process introduces a problem that doesn't exist in most other building environments: the people most vulnerable to construction-related hazards are already on site.

Dust, airborne pathogens, and disrupted airflow don't just create a mess during a hospital renovation — they can cause serious infections in patients who are already immunocompromised. That's where ICRA comes in.

What is ICRA?

ICRA stands for Infection Control Risk Assessment. It is a mandated, multi-disciplinary process used in healthcare facilities to identify, evaluate, and mitigate the infection risks associated with construction, renovation, or maintenance activities taking place in or near active patient care areas.

The process was developed to ensure that construction activity doesn't compromise the health and safety of patients, staff, and visitors. ICRA is not a product or a piece of equipment — it is a systematic planning methodology that guides every decision made before and during a healthcare construction project.

ICRA compliance is required by several regulatory and accreditation bodies, including The Joint Commission (TJC), the Centers for Medicare & Medicaid Services (CMS), and the Facility Guidelines Institute (FGI). Hospitals that fail to implement proper ICRA protocols risk patient harm, regulatory penalties, and loss of accreditation.

The ICRA 2.0 Matrix

The most widely used tool for implementing ICRA is the ICRA 2.0 matrix, developed by the American Society for Health Care Engineering (ASHE). The matrix helps infection control teams and construction managers classify projects by:

• Patient Risk Group — ranging from low-risk areas like administrative offices to high-risk areas like operating rooms, ICUs, and oncology units
• Construction Activity Type — from minor inspections (Type A) to major demolition and new construction (Type D)

By cross-referencing these two variables, the ICRA 2.0 matrix assigns a required level of precaution — known as an ICRA Class — that dictates exactly what containment measures must be in place before work begins.

Why Does ICRA Matter for Hospital Renovations?

Healthcare facilities are never truly "empty." Patients, some with severely compromised immune systems, are present around the clock. Construction activity — even minor work like cutting drywall or replacing ceiling tiles — can release fungi, bacteria, and fine particulate matter into the air. In a standard building, this is an inconvenience. In a hospital, it can be life-threatening.

Aspergillus is one of the most significant risks. This common environmental fungus thrives in dust and soil, and its spores can be easily disturbed by construction activity. For healthy individuals, exposure is rarely a problem. For patients undergoing chemotherapy, organ transplants, or other immunosuppressive treatments, Aspergillus infection can be fatal.

ICRA protocols exist to prevent exactly this kind of outcome. By defining clear containment requirements before work begins, ICRA ensures that construction zones are physically separated from patient care areas, airflow is controlled to prevent cross-contamination, and staff are trained and accountable for maintaining safe conditions throughout the project.

Key ICRA Requirements for Construction Projects

Depending on the ICRA class assigned to a project, containment requirements may include:

• Physical barriers between the construction zone and patient areas, typically temporary wall systems designed to control dust and limit air movement
• Negative air pressure within the construction zone, so that air flows inward rather than outward, preventing contaminants from migrating into patient areas
• HEPA filtration to capture fine particulate matter before air is recirculated
• Tacky mats and sealed penetrations to prevent dust from being tracked out of the work zone
• Designated pathways for workers and materials to enter and exit the construction zone without passing through patient care areas
• Regular monitoring of air pressure differentials to confirm containment is functioning correctly

These measures must be in place before demolition or construction begins, and they must be maintained and inspected throughout the project.

The Role of Temporary Wall Systems in ICRA Compliance

The physical barrier is the foundation of any ICRA containment plan. It is the primary means of separating construction activity from patient care, and it must meet specific performance requirements to be effective.

Traditional plastic sheeting and basic framing were once the standard approach, but they present significant limitations: they are difficult to seal effectively, prone to tearing, and time-consuming to install and relocate as project phases change.

Modern temporary wall systems have been designed specifically to address these challenges in healthcare environments. Imperial Privacy Systems' Rapid Room™ temporary wall system, for example, is a reusable modular panel system engineered for ICRA compliance in active healthcare facilities. The panels are available in multiple widths (12", 18", 24", and 36") and are vertically adjustable to accommodate varying ceiling heights, making them adaptable to a wide range of floor plans and project types.

Rapid Room also offers negative air panels — 24" panels with a built-in differential air pressure monitor that provides a continuous visual indicator of containment status. This allows infection control teams and construction managers to verify at a glance that the barrier is maintaining proper negative pressure, without requiring separate monitoring equipment.

Who is Responsible for ICRA?

ICRA is a shared responsibility. A successful ICRA program requires collaboration between:

• Infection Control Professionals (ICPs) — who assess patient risk and define required precaution levels
• Facility Managers — who understand the physical environment and can identify risks specific to the building
• Construction Managers and Contractors — who are responsible for implementing and maintaining containment measures on site
• Healthcare Architects and Engineers — who incorporate ICRA requirements into project design and specifications

In many facilities, an ICRA permit must be completed and approved by the infection control team before any construction work begins. The permit documents the project type, patient risk level, assigned ICRA class, and the specific containment measures that will be used.

ICRA and Interim Life Safety Measures (ILSM)

ICRA is often implemented alongside Interim Life Safety Measures (ILSM), a related set of protocols required when construction activity temporarily compromises a facility's fire and life safety systems. While ICRA focuses on infection control, ILSM addresses fire suppression, egress, and alarm systems that may be disrupted during renovation.

Both ICRA and ILSM are required components of a compliant healthcare construction project and are typically managed together by the facility's safety and compliance teams.

Planning Your Next Healthcare Renovation

Whether you are managing a minor ceiling tile replacement in a patient corridor or a full-scale department renovation, ICRA compliance is not optional — it is a fundamental requirement of operating a safe healthcare facility.

The right containment system makes compliance more achievable, more consistent, and more cost-effective over time. Reusable temporary wall systems like Rapid Room reduce material waste, speed up installation, and provide the structural integrity and air-sealing performance that plastic sheeting cannot match.
