BACKGROUND: Many hazardous drugs (HDs) are excreted in urine and feces, and evidence has shown that bathrooms of patients receiving chemotherapy at home are contaminated with HDs . However, little information exists on bathroom contamination in ambulatory clinics where HDs are administered .
OBJECTIVES: This project aimed to determine the presence of HD residue in the patient and staff bathrooms of an ambulatory cancer center .
METHODS: A quality improvement project was initiated to examine potential contamination by the HDs 5-fluorouracil and oxaliplatin in a patient bathroom and a secured badge-access staff bathroom in the infusion department of an ambulatory comprehensive cancer center . Twice-daily wipe testing was conducted on the floor in front of the toilet and the flush handle for five consecutive days . FINDINGS: Sixty-five percent of the samples from the floor of the patient bathroom were positive for at least one of the HDs . In the staff bathroom , 35% of the floor samples were positive for at least one HD . None of the flush handle samples were above the level of detection.
