Abstract

Abstract Background: A fundamental requirement to ensure the safety of health care workers is to reduce environmental contamination with cytotoxic medicines. Objectives: The primary objective of this collaborative project between the European Society of Oncology Pharmacy (ESOP) and the European Society for Medical Oncology (ESMO) was to evaluate cytotoxic medicine contamination on surfaces in European hospital wards. The secondary objectives were (a) to detect possible internal bodily exposure in staff members and (b) to evaluate the impact of teaching safe handling practices. Materials and methods: Surface contamination in the chemotherapy administration areas was measured in 28 hospitals from 16 European countries before (part I) and after (part II) staff training through a standardized tutorial. Contamination with four antineoplastic medicines and total platinum was assessed using wipe samples taken from four comparable surfaces in each part of the project. In addition, hospitals that showed a high level of surface contamination, collected 24-hour urine of five staff members (part III). The samples were analyzed by liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS) and inductively coupled plasma-mass spectrometry (ICP-MS). Results: In total, 112 and 104 wipe samples (part I and part II) and 32 urine samples (part III) were collected. Surface contamination occurred in all participating hospitals. The most contaminated spot was the floor in the nurses' station. The most frequently found compound was platinum, and the medicine that showed the highest amount of contamination was cyclophosphamide (8.18 ng/cm2 in part I and 0.53 ng/cm2 in part II). Urine samples were positive for gemcitabine and cyclophosphamide in 1 and 2 nurses, respectively. The intervention by tutorial lowered the levels of contamination, both in number (from 48% to 41%) and in amount of contamination. Conclusion: The MASHA-2 study shows that contamination of surfaces with cytotoxic medicines in European hospitals is a widespread phenomenon. Bodily exposure of nurses was clearly detected. Surface contamination decreased after training on safe handling practices. Nevertheless, further optimization of occupational safety is warranted.
