Boston averages the longest time for a first appointment among the 15 cities surveyed: 45 days. That includes 72 days to see a dermatologist for the first time and 66 days to see a family physician. Boston has earned this dubious distinction in all three surveys the firm has conducted.
Dallas had the shortest wait times, none of them more than 45 days (to see an orthopedic surgeon).
Cities tend to have a higher ratio of doctors to population than rural areas do, so the reason appears to be that demand is simply outstripping supply, as the data I wrote about Thursday seemed to indicate.
These two charts pretty much tell the whole story.
