Wal-Mart Stores is striding into the market for electronic health records, seeking to bring the technology into the mainstream for physicians in small offices, where most of America’s doctors practice medicine.

Wal-Mart’s move comes as the Obama administration is trying to jump-start the adoption of digital medical records with $19 billion of incentives in the economic stimulus package.

The company plans to team its Sam’s Club division with Dell for computers and eClinicalWorks, a fast-growing private company, for software. Wal-Mart says its package deal of hardware, software, installation, maintenance and training will make the technology more accessible and affordable, undercutting rival health information technology suppliers by as much as half.

“We’re a high-volume, low-cost company,” said Marcus Osborne, senior director for health care business development at Wal-Mart. “And I would argue that mentality is sorely lacking in the health care industry.”
