Construction in a healthcare facility isn't like construction anywhere else. Dust and debris that would be minor annoyances in an office building can be life-threatening in a hospital. Airborne fungal spores can increase by up to 1,000 times during renovation work, putting immunocompromised patients at serious risk.

An Infection Control Risk Assessment (ICRA) helps you identify these dangers before they happen.

Learn the essentials of protecting patients during construction, and how Vertix delivers on them.

Understanding Infection Control Risk Assessment in Healthcare Construction

An Infection Control Risk Assessment (ICRA) is a structured process that identifies and stops these infection-related hazards before they harm patients or staff. The numbers tell the story: construction and renovation are linked to nearly half of all hospital-acquired Aspergillus outbreaks.

ICRA isn't a one-time checklist. It's an ongoing strategy that starts before the first wall comes down and doesn't stop until the last worker leaves. Teams assess what's being built, who's nearby, and what could go wrong. Then they build defenses: barriers that seal off work zones, air filters that catch contaminants, schedules that avoid peak patient hours, and backup plans for moving vulnerable patients if needed.

The key is collaboration between the right people. Infection preventionists spot the risks. Facility managers know where every pipe and airflow runs. Construction teams with healthcare experience know how to build without disrupting care. Get these three in a room together, and you've got a project that protects patients while staying on schedule.

Key Steps in Conducting an Infection Control Risk Assessment

A thorough ICRA follows a clear sequence that protects patients while keeping construction on track. It starts with understanding your project's scope and risk level, then moves through selecting the right protections, and finishes with monitoring that ensures everything works as planned.

Project Scoping and Risk Identification

The first step is gathering the right information with your team. The ASHE ICRA 2.0 framework provides a proven approach for evaluating all potential risks during this phase. Here's what you need to map out:

  • Document project boundaries and adjacent areas - Define the exact work zones and locate all patient care areas within 25 feet. Don't forget units above, below, and on the same floor that dust or airflow changes could reach.
  • Classify construction activity type - Is this a simple paint job or a major demolition? The answer determines how much protection you need according to CDC guidelines.
  • Assess vulnerable patient populations - Locate immunocompromised patients, ICU units, surgical areas, and other high-risk populations nearby. Working around patients in 24/7 facilities requires creative separation strategies.
  • Evaluate Critical Utility Systems - Figure out how construction might disrupt HVAC systems, airflow other rooms and corridors affected, relationship of air pressure issues, or affect medical gas lines and other critical building systems including electrical and plumbing systems.
  • Engage infection preventionists early - Bring your infection control team into planning before blueprints are finalized. They spot pathogen risks that construction teams might miss. They also will identify Interim Life Safety Measures (ILSM) needed to be put into place.
  • Establish project timeline and phases - Document realistic timelines and look for opportunities to schedule dusty work during lower-risk periods. On projects like the Sky Ridge Medical Center Cath Lab upgrade, phasing work around vulnerable patients kept care running smoothly throughout construction.

Classifying Project Type and Risk Level

Getting the safety classification right protects lives and prevents costly disruptions. Healthcare facilities use proven systems that match construction activities with patient populations to determine exactly what protections you need.

Here's how it works:

  • Project activities fall into four main types - From simple inspections (Type A) to major demolitions (Type D). Each category is defined by dust generation potential and work complexity, as outlined in the ASHE guidelines.
  • Patient care areas are grouped by vulnerability levels - Low-risk administrative spaces need minimal protection. Highest-risk areas like operating rooms and immunocompromised patient units require maximum safeguards, where even minor dust exposure can threaten patient recovery.
  • Risk matrices combine project type and patient risk - This determines your safety requirements. Class I means basic precautions. Class V requires the most stringent controls, like HEPA filtration, negative air pressure, and sealed barriers.
  • Classification directly drives permit requirements - Minor work may proceed with basic approvals. Class III and above projects need formal infection control permits and specialized oversight throughout construction.

Accurate classification prevents patient safety incidents and costly mid-project changes. Misclassifying a renovation near intensive care units can lead to work stoppages, regulatory violations, and emergency containment measures that disrupt patient care. Get it right from the start, and construction moves forward safely.

Selecting and Implementing Mitigation Measures

Once you've classified the project type and risk level, it's time to put protections in place. The controls you need depend on your project's classification, but they all require tight coordination between construction teams, infection prevention staff, and clinical departments.

Here's what effective mitigation looks like:

  • Install physical barriers that meet fire code requirements - Dust barriers must run floor to ceiling and seal every opening. No gaps means no dust spreading into patient care areas.
  • Establish negative air pressure within work zones - Use HEPA-equipped exhaust systems to keep negative pressure between -0.01 to -0.05 inches of water column. Monitor it continuously with visual indicators.
  • Use HEPA filtration systems that achieve 99.97% efficiency - Portable units should provide at least 6 air changes per hour. Position them with engineering input to ensure proper air circulation.
  • Implement continuous monitoring with daily logs - Particle monitoring should show at least a 90% reduction from outdoor baseline levels. This proves your containment is working.
  • Coordinate workflow adjustments with clinical staff - Schedule work during off-peak hours. Create alternate traffic patterns. Temporarily relocate vulnerable patients when necessary.

Ongoing Monitoring, Documentation, and Communication

Construction projects evolve daily, and infection control measures must adapt alongside these changes. Effective monitoring catches potential issues before they become patient risks. Proper documentation provides the accountability trail that regulators and your quality teams need to see.

Here's how to stay on top of it:

  • Establish daily monitoring protocols - Track pressure differentials, HEPA filtration performance, and barrier integrity. Post documented results at job sites and keep them in project files for compliance reviews.
  • Schedule regular compliance rounds - For higher-risk projects, bring infection prevention teams and construction partners together bi-weekly to assess adherence and provide feedback to all stakeholders.
  • Build clear communication pathways - Connect contractors, infection preventionists, and clinical staff. Create shared protocols for escalating concerns and give everyone authority to address immediate safety concerns when they arise.
  • Maintain comprehensive documentation - Include monitoring logs, particle count measurements, and corrective actions taken. This proves compliance during Joint Commission surveys and internal audits.
  • Coordinate terminal inspections as a unified team - Bring together infection prevention, environmental services, facility management, and construction partners to verify terminal cleaning and approve patient area re-occupancy.
  • Share regular progress updates with all stakeholders - Use reporting to highlight compliance status, address emerging concerns, and celebrate successful infection control efforts across the project team.

Regulatory Requirements for Infection Control in Healthcare Construction

Planning a renovation means navigating rules from different organizations, each with their own expectations for keeping patients safe during construction. It can feel overwhelming. But these rules exist for one important reason: protecting the people in your care.

Three major organizations set the standards:

  • The CDC provides foundational guidelines for environmental infection control
  • The Joint Commission evaluates your compliance during surveys
  • ASHE offers practical guidance specifically for healthcare construction teams

Your accreditation depends on getting this right. When projects don't follow proper protocols, facilities face construction delays, patient relocations, and potential citations. Documentation is critical. You'll need detailed records of risk assessments, safety measures, and monitoring activities throughout the project.

Your contractor's experience matters. Look for construction teams who can demonstrate hands-on experience with these protocols and understand how to work safely around patients and staff. Local health departments often add their own requirements beyond federal guidelines, and organizations like the Facility Guidelines Institute publish specific construction requirements that help ensure your project meets safety expectations from the start.

Working with contractors who treat these requirements as part of good patient care (rather than just paperwork) makes all the difference.

Infection Control Risk Assessment FAQs
