Nosocomial fungal infection during hospital renovation
Abstract:
Nosocomial fungal pulmonary infections (Zygomycetes, Aspergillus sp.) developed in two premature infants in a special care unit (SCU) adjacent to an area of renovation. Inspection showed that inadequate barriers permitted the passage of airborne particles between the two areas, and cultures confirmed a significantly higher (p less than or equal to 0.05) density of mold spores in the SCU (0.88 cfu per hour per settling plate) compared to a construction-free comparison area (0.22 cfu per hour per settling plate). The major source of mold was the dust above the hospital's false ceiling. In another construction area, imperious barriers were shown to effectively restrict the dispersal of mold. Our experience adds Rhizopus to Aspergillus as a possible cause of construction-related nosocomial infection. Sporadic episodes will continue to occur until the hazards of renovation are appreciated and effective preventive measures are routinely instituted.
Insights
Hospital renovations can cause nosocomial fungal infections in premature infants due to airborne mold spores. Effective barriers are crucial to prevent mold dispersal and protect vulnerable patients in special care units.
Area of Science:
- Medical Mycology
- Hospital Epidemiology
- Infection Control
Background:
- Nosocomial fungal pulmonary infections pose a significant risk to premature infants in special care units.
- Hospital renovations present potential environmental hazards that can compromise patient safety.
Observation:
- Two premature infants developed fungal infections (Zygomycetes, Aspergillus sp.) in a special care unit (SCU) adjacent to a renovation area.
- Inadequate barriers allowed airborne particle and mold spore transmission between the renovation site and the SCU.
- Significantly higher mold spore density (p ≤ 0.05) was detected in the SCU compared to a control area.
Findings:
- The primary source of mold contamination was identified as dust above the hospital's false ceiling.
- Rhizopus species, in addition to Aspergillus, were implicated as causative agents of construction-related nosocomial infections.
- Properly implemented barriers effectively prevented mold dispersal in a separate construction zone.
Implications:
- Hospital renovations require stringent infection control measures to prevent nosocomial fungal infections.
- Appreciation of renovation hazards and routine implementation of preventive strategies are essential to safeguard patients.
- Healthcare facilities must prioritize environmental controls to mitigate risks associated with construction activities.
