Big companies may be more likely to offer workers health savings accounts these days than to offer a choice of health carriers.

Researchers in the New York office of PricewaterhouseCoopers L.L.P. have published data hinting at that conclusion in a summary of results from an informal survey of 135 executives at large, U.S.-based multinational employers.

Only 54% of the participants said their companies provided a choice of health carriers, but 64% said their companies now have HSA programs, the researchers report.

The researchers also found evidence to support the belief that large employers will be improving wellness and health information programs.

Although 64% of the participants said their companies offer wellness incentives, only 19% of those participants said the wellness incentives were above-average.

When the researchers asked the participants to compare the state of quality data provided by various industries, more than 50% gave automobile manufacturers and colleges high marks. Only 33% of the participants said health care organizations provide good quality data.
