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. The company plans to team its Sam's Club division with Dell for computers and eClinicalWorks 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.
