Employees were paying an average of $3,354 to cover their share of the costs, according to researchers at the Henry J. Kaiser Family Foundation, Menlo Park, Calif., and the Health Research & Educational Trust, Washington.

The percentage of workers in high-deductible plans has increased to 35% at employers with 3 to 199 workers, from 21% in 2007.
For workers facing deductibles in preferred provider organization plans, the average deductible rose to $560, up about $100 from the 2007 average.
The percentage of employees in plans that incorporate health savings accounts or health reimbursement arrangements has increased to 8%, from 5% in 2007.
