By April, Wal-Mart will include in its stores medical services as it opens in-store health clinics under its trademark. The Clinic at Wal-Mart, a joint venture with local hospitals in Atlanta, Dallas and Little Rock, will soon offer routine medical service for health concerns like colds, bladder infections and sunburn. It will be run by nurses or doctor's assistants.

Clinics had long existed in Wal-Mart stores operated by independent medical practitioners in leased spaces. Clinics in shopping malls have gained popularity over the years with 7 percent of Americans having tried the services of such outlets, the Convenient Care Association said.

With Wal-Mart's lead to package medical services while people are shopping, other chains like CVS Corporation, Target Corporation and Walgreen Company are expected to tie-up with small medical service providers such as RediClinic and MinuteClinic. The CCA estimates that by December the number of in-store clinic would almost double to 1,500 from only 800 in November.

There are 77 existing clinics in different Wal-Mart locations run by tenants. The number excludes 23 in Florida and 3 in other Southern states, outlets of CheckUps which recently closed. Wal-Mart plans to initially open in-store clinics in 200 Supercenters in a cobranding arrangement with local medical institutions.

The world's largest retail chain said it intends to bring up the number of in-store clinics to 400 by 2010. The cobranding arrangement is expected to benefit both Wal-Mart and the local hospital systems.

Patricia Edwards, retail analyst of Wentworth Hauser and Violich, explained, "Especially among middle- and upper-income shoppers, it becomes more like stopping in at any location of their group health care provider. It doesn't have that connotation of going cheap." The Wal-Mart stamp on the clinics will reinforce the chain's efforts to up its public role in health care amid criticism from unions that it has a tight budget on employee health care.

Aside from health services, Wal-Mart introduced $4 generic medicine and promoting the use of electronic health records in lieu of paper files to cut on medical bills.
