Through partnerships with local health care providers, Walmart says its new clinics are the first of their kind, offering a wide variety of services in one facility at an affordable price. Each location is unique and serves as a prototype to test and learn the right mix of health and wellness services for individual communities, the company said. Patients needing a specialist are referred to other providers, but the company says it might offer a wider array of services in the future.

Onsite Walmart Care Hosts and Community Health Workers at each site will help customers navigate their visit, understand resources and be a familiar presence for regular visits.

Elsewhere, retailing and medical services are finding themselves under the same roof in a growing number of locations, and even shopping malls are welcoming doctors' offices.  In Los Angeles, Cedars-Sinai Health System has opened a 32,000-square foot doctor's office at The Runway at Playa Vista, where upscale shops, a movie theater and a Whole Foods are its neighbors.

Malls are increasingly including medical services along with the rest of their offerings, as the health-care industry moves away from centralized campuses to bring services closer to patients, and mall operators are searching for tenants that provide entertainment and services to replace the brick-and-mortar retailers slowly being strangled by Amazon.com and other online retailers.
