L’objectif principal était de décrire la contamination environnementale par des médicaments dangereux du groupe 1 de l’Institut national de la sécurité et de la santé au travail dans les pharmacies d’oncologie et les cliniques externes au Canada en 2019, dans le cadre d’un projet de surveillance annuel.

INTRODUCTION : The primary objective was to describe environmental contamination with National Institute for Occupational Safety and Health Group 1 hazardous drugs in oncology pharmacies and outpatient clinics in Canada in 2019, as part of an annual surveillance project. METHODS : In each participating center, 12 standardized sites (6 in the oncology pharmacy and 6 in outpatient clinic) were sampled. Each sample was prepared to allow quantification of six antineoplastic drugs (cyclophosphamide, ifosfamide, methotrexate, gemcitabine, 5-fluorouracil, and irinotecan) by ultra-performance liquid chromatography-tandem mass spectrometry. Samples were also tested for three additional antineoplastic drugs (docetaxel, paclitaxel, and vinorelbine) without quantification. The impact of certain characteristics of the sampling sites was evaluated with a Kolmogorov–Smirnov test for independent samples. RESULTS : Ninety-three Canadian centers participated in 2019, with a total of 1045 surfaces sampled. Cyclophosphamide was the drug most often found in the surface samples (32.4% of samples with positive result), followed by gemcitabine (20.3%). The front grille inside the biological safety cabinet (81.5% of samples positive for at least one antineoplastic drug) and the armrest of a treatment chair (75.8%) were the most frequently contaminated surfaces. Centers with more oncology inpatient and outpatient beds, those that prepared more antineoplastic drugs each year, and those that used more cyclophosphamide each year had higher concentrations of cyclophosphamide contamination on the surfaces tested (p < 0.0001). CONCLUSION : Traces of dangerous drugs were found in oncology pharmacies and oncology outpatient clinics in 93 Canadian hospitals in 2019. However, the quantities measured were very small. Every healthcare worker should consider these work areas to be contaminated and should wear appropriate protective equipment. Consultez la page de l’article
