The VHA is the integrated health system providing healthcare to US military veterans managed by the Department of Veteran Affairs. It is currently regarded by by some other health systems as a model to learn from (see here for a recent report about how the UK's NHS could learn how to implement integrated electronic health records effectively, something it has spent a lot of money on without producing useful results).
Philip Longman's book Best Care Anywhere argues that the VHA offers its members some of the highest quality care available anywhere in the US while doing so within a very frugal budget. To quote from the Amazon summary (my emphasis):
This important book describes the turnaround of the VA health-care system—now widely recognized as leading the nation in terms of both quality and costs—and offers insights that will be useful to patients and policymakers alike.
Better quality and cheaper care: is this true?
Update
In a recent (2018) article on infighting among Trump officials running the VHA, The Economist reports an explanation of why many Americans find it so hard to believe the VHA does a good job (counter to the widespread belief in the USA that "socialised" medicine is always bad). My emphasis:
For many Americans, the phrase “veterans’ health care” conjures images of scandal and ineptitude. Much of this is because of a crisis in 2014, when it was discovered that hospital officials had falsified records to avoid reporting delays in appointments. Heads rolled when it appeared that 40 ex-servicemen had died while waiting for appointments. Less coverage was given to later investigations, which have been largely unable to blame the deaths on the extended waiting times.
But the reality is different:
Most Americans would be shocked to learn that the VA health system actually seems to provide higher-quality care than its competitors. A review by the RAND Corporation showed that the VA outperformed non-VA care on 45 of 47 outpatient quality measures. More than 80% of new primary care patients are able to get an appointment within two weeks. Annual surveys show satisfaction levels with treatment close to 80%. In-patient care was more mixed, however, and performance tends to vary greatly between hospitals. Clearly the system needs fixing, but fundamentally broken it does not appear to be.
