How is a risk assessment conducted for a renovation with regard to infection control and patient safety?

• A. Review unpublished design plans, identify hazard points, model infection transmission, define controls (negative pressure rooms, spacing), and verify through simulations
• B. Consult only during construction; defer infection control assessment until completion
• C. Ignore design plans and rely on post-occupancy data
• D. Rely on generic guidelines without site-specific modeling

Answer: (C)

Proactive planning during the renovation is essential for infection control and patient safety. A solid risk assessment starts with reviewing unpublished design plans to understand the proposed layout and how spaces connect, so you can identify hazard points where infection could spread or patients could be exposed. Then you model how infection could transmit through factors like airflow, crowding, and spacing under different renovation scenarios to see where risks are highest. Based on that analysis, you define specific controls—such as appropriate ventilation and pressure relationships, layout changes, isolation cues, and cleaning protocols—and you verify these controls through simulations or pilot tests before spaces are used. Relying only on post-occupancy data misses critical lead time to prevent transmission and neglects design-stage opportunities to mitigate risk. Skipping design-plan analysis or relying on generic guidelines without site-specific modeling can leave gaps because the actual layout and airflow patterns drive how infections might spread. By combining design information, hazard identification, quantitative modeling, and validation, the risk assessment effectively protects patient safety during the renovation.
