Amazon's joint health-care venture finally has a name: Haven

These include: Improving the process of navigating the complex health-care system, and accessing affordable treatments and prescription drugs.Haven also said on its website that it's interested in working with clinicians and insurance companies to improve the overall health-care system, suggesting the venture wants to work with existing players such as insurers, providers and pharmacy benefit managers rather than uprooting them.The website also includes a letter where Gawande describes Haven's role as being "an advocate for the patient and an ally to anyone — clinicians, industry leaders, innovators, policymakers, and others — who makes patient care and costs better."That follows a statement from Haven Chief Operating Officer Jack Stoddard, who recently said the group wants to make health care easier to understand, less expensive and ideally produce better outcomes for employees, according to court testimony in a hiring dispute between the new venture and a unit of insurer UnitedHealth Group.And at a dinner during J.P. Morgan's annual health-care conference in January, Dimon told a room of industry leaders that he and his partners "are not happy with health-care costs and want to help," according to two people with knowledge of the event who asked not to be named because it was private.Here's the full copy of the memo from Gawande:As a surgeon, I've devoted my career to caring for my patients and working to make the health care system better.
