Use of the CPT in an Acute Medical Setting

[LA503]

I am working with a team of therapists in an Acute Medical setting to develop a cognitive assessment protocol- to be used for those patients that the therapist screens a need for, or the MD orders further cognitive evaluation. (Target question- appropriate level of supervision post discharge).
Assessment must be completed and written up (use of templates encouraged) within one hour. To be completed in/or around patients room (if ambulatory, walking short distance in hallway reasonable).
I am from a dementia background and very comfortable with the Allen Cognitive Disability Theory. By chance someone in the department purchased the CPT- but they have never used it.
I note in the introduction that the test can still be valid with fewer than the complete 7 subtests.
What do you think of the validity of substituting the leather lacing screen as one of the subtests? That, handwashing, medication and one more (perhaps phone?) could be completed in 45 if all the stars were aligned.
Or other ideas?
Thanks.
