Assessing the Impact of Employee Cost-Sharing on Health Care Costs and Outcomes, Phase 1


In an effort to alleviate their rising health care costs, employers have sought to share more of these expenses with their workers. To assess the impact of changes in employee cost-sharing on the use, cost, and quality of preventive and therapeutic care, the project investigators will examine medical claims and personnel data at two or three St. Louis firms for up to 70,000 employees and dependents. The analysis will include a special focus on workers earning low to moderate wages. If this work proceeds satisfactorily, a second phase will be proposed to assess the effect of cost-sharing on emergency room visits, inpatient hospitalization, and mortality. Study findings will inform policymakers and employers about the personal health and financial implications of imposing higher levels of cost-sharing. Cofunders are being sought for this project.
