Handling of antineoplastic drugs: a health concern among health care workers.

Introduction: Health care professionals are part of a group that is more exposed to a wide range of sources of risk that are very harmful to their own health. Antineoplastic drugs are widely used to treat many different types of cancer and are very aggressive to both patients and health care professionals.

Objectives: To identify occupational risks and assess knowledge in health care professionals from Porto Alegre whose work involves handling antineoplastic drugs.

Methods: This was a prospective, descriptive, and cross-sectional study with qualitative and quantitative analyses. It was conducted in two stages. A questionnaire containing objective questions was administered in stage one. In stage two, observations were made during regular visits to the sites studied at different times, following a checklist based on the requirements of health regulation standards relating to handling of antineoplastic drugs.

Results: A total of 40 health care professionals took part in the study, 11 nurses, 14 pharmacists, and 15 nursing and/or pharmacy technicians. Twenty-seven of them had been involved in some type of accident during their professional practice. It was also observed that the institutions were making efforts to comply with legal requirements, since 32 reported that they took part in the Program for Medical Control of Occupational Health and 29 of the employees stated they had had some type of training in the antineoplastic area.

Conclusions: Exposure to antineoplastic drugs through contact, aerosols, ingestion, and inhalation was detected. Additionally, ergonomic, physical, and biological risks were also present, since working with different pathological organisms and working processes impacts on these workers' health. Assessment of the health care professionals' knowledge identified a lack of knowledge and weaknesses with relation to handling this class of drugs.
