Worker Productivity | Work-Related Musculoskeletal Disorders (WMSDs) Evaluation Measures

Worker productivity measures for WMSD prevention1-7

Healthier employees are less likely to call in sick. Companies can sometimes assess sick day use to determine whether health programs are increasing worker productivity.

Baseline

  • Determine the average number of sick days per employee over the previous 12 months related to musculoskeletal disorders
    • This measure may be less useful if there has been a large increase or decrease in numbers of employees over the past 12 months
  • Determine the costs of worker absenteeism related to WMSDs including costs of replacement workers, costs in training replacement workers, and loss and delay in productivity
  • Determine time employees spend during working hours participating in WMSD related worksite prevention programs
  • Additional validated surveys have been developed to provide employers with information about the indirect costs of untreated or undertreated employee health issues such as arthritis or back pain. Employers who use these health and productivity surveys on an ongoing basis can begin to evaluate the return on investment (ROI) of offering WMSD prevention programs on employee absence or productivity. These surveys may be proprietary and may require a modest fee to use. Two examples are provided below:
    • Health and Work Performance Questionnaire (HPQ)external icon is a short, easy to administer self-report survey designed to estimate workplace indirect costs (absenteeism, reduced productivity, and injury due to accidents) of employee health problems developed by the World Health Organization (WHO) and the Harvard Medical School
    • The Work Limitations Questionnaire (WLQ)external icon developed by the Health Institute at Tufts Medical Center is an easy to use questionnaire that addresses general work limitations which can be built into other health assessment tools such as a health risk appraisal or employee health survey

Process

  • Re-assess the average number of sick days per employee at the first follow-up evaluation
    • If employee education programs are successful such as ergonomics awareness, these measures may increase in the short term as screening and detection rates for WMSDs increase
  • Periodic repeats of baseline measures

Outcome

  • Assess changes in the average number of sick days per employee in repeated follow-up evaluations
  • Assess changes in costs from baseline (e.g., absenteeism)
  • Assess changes in time employees spend during working hours participating in WMSD related worksite prevention programs
