Retail and technology giant Amazon (Nasdaq: AMZN) last month announced plans to acquire primary care innovator One Medical for an astounding $3.9 billion.

The transaction doesn’t immediately affect senior-focused in-home care providers, but it’s another major stepping stone on the path toward disrupting the current U.S. health care system. What’s more, the deal reflects the ongoing consumerization of health care and steady emergence of nontraditional players, many of which have already revealed their home-based care designs.

“I think the future health care is all about thinking about how you can keep people healthier and deliver better outcomes, with reduced costs,” Erin Ney, an expert associate partner at Bain & Company’s health care practice, told Home Health Care News. “And being able to engage with people in their homes.”

Once finalized, One Medical will give Amazon substantial primary care capabilities to pair with its existing health care assets, which include Amazon Care and an online pharmacy. Additionally, on top of its 188 medical offices and about 790,000 members, One Medical owns Iora Health, which delivers value-based care for older adults enrolled in Medicare Advantage (MA) and alternative payment models.
