What the count covers

1,342 NPPES records list certified registered nurse anesthetist (367500000X) as their primary taxonomy with a practice address in Massachusetts: 19 per 100,000 residents against 23 nationally (50 states and D.C.). Boston has 364 of them (27%).

A record is a registration a provider made and keeps up to date: it shows neither that the provider is licensed nor that they still practice there. The state's own license search is the check.
