- To determine the most stressful clients handling tasks
- To conduct an ergonomic evaluation of these task
- To find less stressful methods for carrying out these tasks, and
- To apply the less stressful methods in the clinical setting.
The ergonomic process involved identifying the jobs and specific task within those jobs that impose great stress on the back; studying and pilot testing ways to change the task demand; and implementing these changes in the work setting.
The study took place in two setting: a nursing/long-term care facility in which 38 nursing assistants ( two were males) ranging in age from 19 to 61 tears participated, and a laboratory in a university school of nursing in which six senior nursing students participated. participants listed the client handling tasks they perceived as most stressful in their duties. An ergonomic evaluation was then completed on the ten tasks perceived as most stressful.
The tasks ranked as most stressful were transferring the client on and off the toilet and in and out bed, and the transfers involved in bathing and weighing clients. The participants reported that they felt the greatest amount of exertion in the lower back. Problems encountered in the transfers were the presence of railings around toilets, unequal height of toilet and wheelchair seats, and stress levels related to the use of hoists. Problem with the use hoists resulted from body postures the nurses needed to assume in order to position the slings and the effort needed to push the hoist with the client in it.
Of the manual lifting techniques used, the method of lifting client under the axilla was perceived to be the most stressful; the walking belt was rated the least stressful. the most commonly used assistive device was the walking belt.
Implication : To minimize back pain, nurse need to explore ways to change environmental impediments, such as altering railings around the toilet and raising toilet seat levels. furthermore, nurses need to learn to use transfer device effectively.
