ABSTRACT
The purpose of this study was to examine the relationship of health risk level to charged medical costs and determine the excess cost of higher risk individuals compared to low risk. Two years of medical claims from six corporations were used to determine costs of health risk assessment (HRA) participants and nonparticipants. A total of 165,770 employees, 21,124 of which took an HRA, were used for the study. Costs increased as risk level increased. There were no significant differences within a risk level between companies for the cost ratio. Percent of medical costs due to excess risk ranged from 15.0-30.8% for HRA participants and 23.8-38.3% for the study population. Cost patterns were consistent across companies. Excess cost as the result of increased risk level accounted for a substantial portion of the cost at each company. These results can be used to justify the need for a health-promotion program and to estimate potential savings as the result of excess risk. Even without the use of an HRA, health practitioners should feel confident stating that excess risk accounts for at least 25% to 30% of medical costs per year across a wide variety of companies, regardless of industry or demographics. The numbers can be used as a realistic estimate for any health promotion program financial proposal.

The purpose of this study was to combine absences, short-term disability, and workers' compensation into a sum of the cost of time away from work (TAW) and compare it with health risk status and individual health risks of 6220 hourly workers at Steelcase Inc. The study used 3 years (1998 to 2000) of TAW and health risk appraisal data. Higher TAW costs were associated with illness days, drug/medication use, the individual's lower perception of physical health, job dissatisfaction, high stress, life dissatisfaction, and physical inactivity. More high-risk individuals (80.6%) had a TAW occurrence than medium- (72.8%) and low-risk (61.1%) individuals. High-risk individuals had higher TAW costs than medium- and low-risk individuals. Of the total TAW costs, 36.2% was attributed to the excess risks of the medium- and high-risk individuals or nonparticipants compared with low-risk participants. If TAW costs follow risk reduction, a potential annual savings of $1.7 million could be achieved.
