PFAS Sources in Hospital Environments
Hospital environments contain numerous PFAS sources beyond drinking water. Medical devices including catheters, guidewires, and endoscopes use PFAS coatings for lubricity and biocompatibility. Surgical drapes and gowns treated with PFAS repel fluids and maintain sterility. Healthcare workers in frequent contact with these materials — particularly surgical team members and interventional procedure staff — accumulate PFAS from dermal and inhalation routes.
Hospital cleaning products, floor finishes, and stain-resistant upholstery on patient furniture contribute to ambient PFAS in indoor air. PFAS outgassing from treated textiles and surfaces is higher in warm, enclosed hospital spaces, and healthcare workers spending long shifts in these environments receive ongoing low-level inhalation exposure.
Occupational Health Monitoring
Occupational health programs specifically addressing PFAS in healthcare settings are limited but growing. A study of operating room nurses found PFAS blood levels correlated with years of employment and frequency of surgical case involvement, consistent with occupational exposure from surgical materials. Phlebotomists and laboratory staff handling patient blood samples are exposed to PFAS that may transfer from specimen collection tubes containing fluoropolymer gaskets.
The epidemiological evidence for health effects specific to healthcare workers’ PFAS exposure is limited by the small number of studies. However, nurses and hospital workers are a workforce with well-established occupational health infrastructure, making them accessible for exposure monitoring and health surveillance.
Risk Reduction in Clinical Settings
Healthcare institutions can reduce PFAS exposure by specifying PFAS-free alternatives when replacing medical equipment and facility furnishings. Several medical device manufacturers now offer PFAS-free catheter and guidewire options that match performance characteristics of fluoropolymer-coated devices for many applications.
Institutional water quality — particularly in hospitals where water is used in patient care, CSSD sterilization, and laboratory procedures — should be monitored for PFAS and filtered where contamination is present. Staff canteens and water stations in PFAS-affected hospitals should provide certified filtered water.
