Objective: The objective of this study was to determine the prevalence and estimate total costs for chronic health conditions in the U.S. workforce for the Dow Chemica Company (Dow). Methods: Using ...the Stanford Presenteeism Scale, information was collected from workers at five locations on work impairment and absenteeism based on self-reported "primary" chronic health conditions. Survey data were merged with employee demographics, medical and pharmaceutical claims, smoking status, biometric health risk factors, payroll records, and job type. Results: Almost 65% of respondents reported having one or more of the surveyed chronic conditions. The most common were allergies, arthritis/joint pain or stiffness, and back or neck disorders. The associated absenteeism by chronic condition ranged from 0.9 to 5.9 hours in a 4-week period, and on-the-job work impairment ranged from a 17.8% to 36.4% decrement in ability to function at work. The presence of a chronic condition was the most important determinant of the reported levels of work impairment and absence after adjusting for other factors (P < 0.000). The total cost of chronic conditions was estimated to be 10.7% of the total labor costs for Dow in the United States; 6.8% was attributable to work impairment alone. Conclusion: For all chronic conditions studied, the cost associated with performance based work loss or "presenteeism" greatly exceeded the combined costs of absenteeism and medical treatment combined.
Workforce productivity has become a critical factor in the strength and sustainability of a company's overall business performance. Absenteeism affects productivity; however, even when employees are ...physically present at their jobs, they may experience decreased productivity and below-normal work quality—a concept known as decreased presenteeism. This article describes the creation and testing of a presenteeism scale evaluating the impact of health problems on individual performance and productivity. A total of 175 county health employees completed the 34-item Stanford Presenteeism Scale (SPS-34). Using these results, we identified six key items to describe presenteeism, resulting in the SPS-6. The SPS-6 has excellent psychometric characteristics, supporting the feasibility of its use in measuring health and productivity. Further validation of the SPS-6 on actual presenteeism (work loss data) or health status (health risk assessment or utilization data) is needed.
Objective: This study reports the reliability and validity of the 13-item Stanford Presenteeism Scale (SPS). The SPS differs from similar scales by focusing on knowledge-based and production-based ...workers. Methods: Data were obtained from administrative and medical claims databases and from a survey that incorporated the SPS, SF-36, and the Work Limitations Questionnaire. Results: Sixty-three percent (7797) of employees responded. Cronbach's alpha (0.83) indicates adequate reliability. Factor analysis identified two underlying factors, "completing work" and "avoiding distraction." Knowledge-based workers load on "completing work" (α = 0.97), whereas production-based workers load on "avoiding distraction" (α = 0.98). There were significant and positive relationships between the SPS, SF-36, and Work Limitations Questionnaire. Conclusions: The SPS demonstrates a high degree of reliability and validity and may be ideal for employers who seek a single scale to measure health-related productivity in a diverse employee population.
Many employers in the US are investing in new programmes to improve the quality of medical care and simultaneously shifting more of the healthcare costs to their employees without understanding the ...implications on the amount and type of care their employees will receive. These seemingly contradictory actions reflect an inability by employers to accurately assess how their health benefit decisions affect their profits. This paper proposes a practical method that employers can use to determine how much they should invest in the health of their workers and to identify the best benefit designs to encourage appropriate healthcare delivery and use. This method could also be of value to employers in other countries who are considering implementing programmes to improve employee health. The method allows a programme that improves workers' health to generate four financial benefits for an employer - reduced medical costs, reduced absences, improved on-the-job productivity, and reduced turnover - and uses accurate estimates of the benefits of reducing absences and improving productivity.
