when using surge protectors for resident rooms in a long term building, do they have to be hospital grade
I am not aware that any SPD's (Type 1-3) are rated as Hospital Grade. Also the Type 4 models that manufacturers typically install are also to the best of my knowledge not hospital grade. There are various statements within the NEC in terms of receptacles being "hospital grade" in locations like Patient Bed Locations and Operating Rooms for example but that does not apply to the perceived use of an SPD, only receptacles. Now it is clear in Article 285, most notably in Section 285.5 that they have to be listed but it does not specify anything regarding being "hospital grade" in both Article 285 or 517.

When you use the term "surge protectors" are you referring to devices commonly called "power strips" which plug into a wall outlet?
If so then UL 1363 calls them "Relocatable Power Taps" (RPT) and if they have surge protection (formerly called Transient Voltage Surge Suppressors, TVSS) the they're classified as a type 3 SPD as identified by UL 1449.
According to both standards they should not be used in "General Patient Care Areas or Critical Patient Care Areas" because they haven't been evaluated for use where Article 517 from the NEC require hospital grade components. However they can be used in other areas such as business offices, waiting rooms, etc where patients are not treated or examined.
However an addendum to UL 1363 called Subject UL 1363A for "Special Purpose Relocatable Power Taps" (SPRPT) addresses the use of SPRPT in medical and health care facilities. I was able to find a few power strips on line which according to the manufacturers meet the criteria for SPRPT and UL 1363A for use in patient care areas. I have no personal experience with them so I can't speak one way or another about the validity of the claims.
However here's a pdf from UL about RPTs and SPRPTs in medical facilities.
