A large money manager says health plans that incorporate personal health accounts seem to be popular with its corporate customers’ employees.[@@]

Researchers at Fidelity Employer Services Company, the benefits administration arm of Fidelity Investments, Boston, say 3.9% of the members in corporate customers’ health plans now have health savings accounts, health reimbursement arrangements or other personal health accounts, up from 1.1% a year ago.

When employees with account-based plans have an option to shift to another type of plan, about 95% stick with the account-based plan, and that retention rate is comparable to the retention rate for other types of health plans, according to the Fidelity Employer Services researchers.

In general, all employee efforts to shift to cheaper plans helped hold the overall average increase in premium costs to about 6%. If employees had stayed in the same plans, the overall average would have increased 9%, according to the Fidelity Employer Services researchers.
