Ohio holds the tightest RN supervision cap on file: two per physician
One number governs how many registered nurses a single physician can stand behind in Ohio. This week we look at the only jurisdiction on file that puts a hard cap on RN supervision.
The tightest supervision ratios for registered nurses
1 jurisdictions cap how many registered nurses one physician may supervise or collaborate with; these are the lowest caps on file.
Ohio: 2 per physician
Ohio is the one jurisdiction in our data that caps the number of registered nurses a single physician may supervise or collaborate with, at two. For a practice running RN-delivered injectables or infusions under a standing order, that number sets how many nurses one medical director can cover before a second physician has to be named.
