Follow-up Evaluation

This follow-up evaluation should use the same risk factor checklist or other method of job analysis that first documented the presence of ergonomic risk factors. If the hazards are not substantially reduced or eliminated, the problem-solving process is not finished.

The follow-up may also include a symptom survey, which can be completed in conjunction with the risk-factor checklist or other job analysis method. The results of the follow-up symptom survey can then be compared with the results of the initial symptom survey (if one was performed) to determine the effectiveness of the implemented solutions in reducing symptoms.

Because some changes in work methods (and the use of different muscle groups) may actually make employees feel sore or tired for a few days, follow-up should occur no sooner than 1 to 2 weeks after implementation. A month is best. Recognizing this fact may help avoid discarding an otherwise good solution. If the follow-up evaluation uncovers new and unexpected risk factors in the task, it may be the result of introducing too many variables into the new procedure.

Long-term indicators of the effectiveness of an ergonomics program can include:

• reduction in the incidence rate of musculoskeletal disorders
• reduction in the severity rate of musculoskeletal disorders
• increase in productivity or the quality of products and services
• reduction in job turnover or absenteeism

The above-mentioned indicators offer bottom-line results in evaluating interventions that have been put into place. Other indicators may also be used that represent in-process or interim accomplishments achieved on the path to building an ergonomic program. For example, the extent of the ergonomic training given the workforce, the number of jobs analyzed for potential problems, and the number of workplace solutions being implemented.
