OBJECTIVES Studies examining healthcare workers' exposure to antineoplastic drugs have focused on the drug preparation or drug administration areas. However, such an approach has probably underestimated the overall exposure risk as the drugs need to be delivered to the facility, transported internally and then disposed. The objective of this study is to(More)
We previously reported that there is a potential for antineoplastic drug contamination throughout the hospital medication system (process flow of drug within a facility from delivery to waste disposal) due to the various surfaces contacted by health care workers. This article describes the contamination of these frequently contacted surfaces as well as(More)
OBJECTIVE To identify priorities for further research in protecting healthcare workers (HCWs) from severe acute respiratory syndrome (SARS) and other respiratory pathogens by summarizing the basic science of infectious bioaerosols and the efficacy of facial protective equipment; the organizational, environmental, and individual factors that influence the(More)
OBJECTIVE We undertook a pilot study involving six British Columbian hospital pharmacies to determine if antineoplastic drug contamination of surfaces exists and whether residual drugs remain on these surfaces despite being cleaned. METHODS At each site, the pharmacy technician responsible for preparing the antineoplastic drugs was observed to determine(More)
Although nurses are knowledgeable regarding the risk of exposure to antineoplastic drugs, they often do not adhere with safe work practices. However, the knowledge, perceptions, and behavior of other health care job categories at risk of exposure has yet to be determined. This study aimed to survey a range of health care workers from British Columbia,(More)
BACKGROUND It is believed that health care workers are exposed to antineoplastic drugs primarily via dermal contact. However, levels of occupational dermal contamination in Canada have not been formally investigated. OBJECTIVE To determine the potential dermal exposure to antineoplastic drugs among hospital pharmacy personnel in a metropolitan area in(More)
Occupational exposure to antineoplastic drugs has been documented to result in various adverse health effects. Despite the implementation of control measures to minimize exposure, detectable levels of drug residual are still found on hospital work surfaces. Cleaning these surfaces is considered as one means to minimize the exposure potential. However, there(More)
We used observational evaluation to assess the ability of an online learning course to effectively transfer knowledge on personal protective equipment (PPE) selection and removal. During orientations for new hospital staff, 117 participants applied either airborne, droplet, or contact precautions in mock scenarios. Postcourse, all 3 scenarios demonstrated(More)
PURPOSE The purpose of this study was to quantify the urine concentration of non-metabolized cyclophosphamide (CP), a commonly administered antineoplastic drug, among potentially exposed Canadian healthcare workers and to identify factors associated with the drug concentration levels. METHODS Participants were asked to provide two sets of 24-h urine(More)
We previously reported that antineoplastic drug contamination is found on various work surfaces situated throughout the hospital medication system (process flow of drug within a facility from initial delivery to waste disposal). The presence of drug residual on surfaces suggests that healthcare workers involved in some capacity with the system may be(More)
