Work-related stressors have been linked to a number of diseases, both physical and psychological. Previous studies have revealed that the stressful occupational components are particularly apparent in health care occupations. Occupational sources of stress in three allied health disciplines--nuclear medicine technology, radiologic technology, and medical technology--were studied over the last three years via responses from approximately 500 practitioners. The top five stressors in each discipline were as follows: nuclear medicine technology--equipment malfunctions, add-on examinations, uncooperative physicians, lack of staff, and uncooperative patients; radiography--disrespectful physicians, inadequate pay, unnecessary examinations, lack of staff, and lack of respect; and medical technology--equipment breakdown, poor management practices, difficult coworkers, lack of time, and exposure to human immunodeficiency virus. It is crucial for administrators and fellow health care professionals to be aware of and address those areas of job-related stress that may impact the quality of patient care and the well-being of the allied health professional.
