There's emerging evidence that long waits to get a doctor’s appointment have become the norm in many parts of American medicine, particularly for general doctors but also for specialists, says The New York Times.
People with private insurance can face long waits, as well as those with Medicaid or Medicare, the paper says.
On the other hand, waiting sometimes can be a good thing, the NYT says:
"There is widespread agreement that Americans receive unnecessary treatment when it is profitable to do so. For example, they are far more likely to get steroid injections or surgery for back pain than people in other countries, even though medical guidelines suggest six weeks of conservative treatment before other interventions are tried; backs often heal on their own, and there are risks to the procedures."
