Nurses routinely face the risk of direct exposure to hazardous drugs due to their key role in the administration of medication. Exposure can happen during all stages of administration: when connecting IV bags to administration sets, when connecting administration sets to patients, during drug transfer and administration, when disconnecting, and during disposal of used IV equipment.
Exposure to toxic drugs as droplets or vapor can occur through inhalation, skin contact, unintentional hand-to-mouth ingestion or accidental needle stick and sharps injuries. In wards, and especially oncology wards, unintentional exposure to hazardous drugs
poses a risk not only to nurses, but also to other hospital personnel, patients and their families, and the environment.
Studies show that nurses who handle antineoplastic drugs are exposed to the active ingredients. Furthermore, nurses who work with antineoplastic drugs show more chromosomal aberrations and an increase in birth defects that appear to be related to frequency of use. In addition, there is an increased risk of spontaneous abortion with exposure to antineoplastic drugs. Additional acute effects of exposure to hazardous drugs include skin rashes and nausea, while chronic effects include infertility, leukemia and other cancers.
