Enter Sam's Club. Like the bundled packs of condiments that include ketchup, mustard and relish, the wholesale outlet now allows physicians to add bundled EMR systems to their electronic cart. Last month, the Wal-Mart subsidiary that includes software, hardware and technical support in three states -- Illinois, Georgia and Virginia -- as a test bed for offering the software as a service (SaaS) product throughout the U.S.

So far, interest is "extremely strong," said Susan Koehler, a spokeswoman for Sam's Club, although the company could not offer any sales figures.

While it may seem odd for a wholesale retailer to dip its toes into the health care technology market, physician practices that lack any technical support could use a SaaS model to cover the technical aspects of EMRs.

Helping spur the adoption of SaaS models in health care is the U.S. government, which has been ambiguous about which EMR systems will qualify for up to $44,000 in reimbursement funds beginning in 2011, according to Judy Hanover, an analyst on health care information technology at IDC in Framingham. Hanover said that fewer than 10% of private practices have deployed any kind of comprehensive EMR system thus far.

President Barack Obama has said the government's plan under the , or HITECH, is to have a nation-wide EMR network in place within five years. EMRs will not only enable the sharing of patient medical information between facilities, pharmacies and laboratories -- ensuring the most up-to-date patient information is available -- but it should help speed care and ensure the use of best practices.
