Provide an example of a high-risk scenario in ICRA and its mitigation.

Provide an example of a high-risk scenario in ICRA and its mitigation.

• A. Construction near a non-patient care area with standard PPE.
• B. Renovation of a general ward with no air filtration upgrade.
• C. Construction far from any patient areas but with minor dust.
• D. Construction near an immunocompromised patient ward; mitigation includes full barrier system, negative pressure, HEPA exhaust, strict PPE use, and patient relocation if needed.

Answer: (D)

High-risk scenarios in Infection Control Risk Assessment occur when construction or renovation happens near spaces housing immunocompromised patients, where the potential for airborne dissemination of dust, spores, or other contaminants is greatest. In these situations, mitigation must be comprehensive: establish a well-sealed construction zone with barriers to prevent dust migration; maintain negative pressure in the construction area so air flows toward the zone and not into patient areas; use HEPA filtration or exhaust to capture contaminants that do escape; enforce strict PPE and procedural controls for workers; and relocate vulnerable patients if needed to reduce exposure risk. This scenario is the best answer because it describes the combination of proximity to highly susceptible patients and the strongest, multi-layered controls to protect them. Other scenarios present lower risk: construction near a non-patient care area with standard PPE involves less potential for patient exposure; renovation of a general ward without air filtration upgrades still carries risk but lacks the strongest containment; construction distant from patient areas with only minor dust presents the least risk and requires far less intensive measures.
